2014-11-01T03:00:37 < jadew> upgrdman, one that defines new states based on input
2014-11-01T03:01:04 < upgrdman> hmmm ok
2014-11-01T03:01:49 < jadew> kinda hard to imagine one if you don't know of an exmaple from the top of your head, but I'm sure it exists
2014-11-01T03:03:20 < jadew> in other notes, that guy didn't fix the issue and didn't answer since he said "he'll ask ebay" and my OCXO started to misbehave in my freq. counter
2014-11-01T03:05:31 < jadew> and with the internal TCXO it's off by 48 Hz @ 10 MHz :/
2014-11-01T03:07:07 < jadew> oh wait, 480 Hz, I was feeding it 1 MHz

2014-11-01T03:23:56 < upgrdman> my latest innovation: almost melting aluminum with my induction heater.  https://www.youtube.com/watch?v=2YnMfWRlLC8
2014-11-01T03:24:50 < dongs> any eagle pros here
2014-11-01T03:24:53 < dongs> how the fuck do i measure anything
2014-11-01T03:25:05 -!- CrazySlippers [~Peter@dhcp-040164.eduroam.chalmers.se] has quit [Ping timeout: 244 seconds]
2014-11-01T03:27:10 < upgrdman> :) will need to reposition coil vertically and see if i can melt blob off of the strip of aluminum
2014-11-01T03:29:04 < upgrdman> no real plans.
2014-11-01T03:29:38 < upgrdman> i suppose i could parallel some more FETs and build it properly if i ever want to heat treat tool steal or someshit.
2014-11-01T03:30:08 < upgrdman> the SMPS-rated MLCC caps worked great. get warm but not hot (when in a water bath)
2014-11-01T03:30:56 < upgrdman> R2COM: heat treating is when you heat and then cool (rapidly or slowly) a metal to harden it. need to be done with precision, but would be fun to mess around with anyway.
2014-11-01T03:31:11 < upgrdman> like case-hardening a drill bit or something stupid like that
2014-11-01T03:32:02 < upgrdman> doubt it. the thing you heat needs to be electrically conductive.
2014-11-01T03:32:12 < dongs> comeon who the fuck uses eagle, how do I measure distance between 2 points
2014-11-01T03:32:28 < BrainDamage> upgrdman: what frequency and power?
2014-11-01T03:32:30 < upgrdman> the coil is the "primary" of a transform, and the thing you heat is essentially a short-circuited secondary
2014-11-01T03:32:37 < BrainDamage> oh durr, the power is in the video
2014-11-01T03:32:48 < upgrdman> BrainDamage: 60ish kHz, 240ish Watts

2014-11-01T03:33:39 < dongs> yeah it doesnt work
2014-11-01T03:33:41 < dongs> it snaps to some shit
2014-11-01T03:33:49 < dongs> that isnt edges of pad i wanna measure
2014-11-01T03:34:26 < BrainDamage> upgrdman: have you estimated the efficiency?
2014-11-01T03:34:49 < upgrdman> BrainDamage: don't know how.
2014-11-01T03:35:05 -!- emeb_mac [~ericb@ip72-201-77-218.ph.ph.cox.net] has joined ##stm32
2014-11-01T03:35:13 < BrainDamage> upgrdman: heat something a bit insulated from air, for a known time
2014-11-01T03:35:15 < upgrdman> R2COM: good idea. let's just put some iron filings in the engine oil. problem solved ;)
2014-11-01T03:36:34 < upgrdman> BrainDamage: hmm. would it be easier to just measure the temp delta in my water bath and water tank, convert from calories to watt-hours, and see what percentage of power input that is? wouldn't take into account radiated heat, but i think that might be minimal.
2014-11-01T03:36:37 < BrainDamage> upgrdman: energy = power*time ( if power is constant ), measure the original temp of the object before heating, and temp after x seconds of heating, if we neglect losses towards environment, the thermal energy it acquired would be thermal_capacity*deltaT, thermal capacity is a material spec
2014-11-01T03:37:04 < upgrdman> hmm ok

2014-11-01T03:37:50 < BrainDamage> that'd neglect the switch converter losses, it's better to measure directly the to_be_heated object
2014-11-01T03:38:00 < upgrdman> k
2014-11-01T03:38:47 < BrainDamage> also pay attention of the thermal capacity units you'll find, some will be volumetric ( as in per m^3 ) and some would be massic ( per kg )
2014-11-01T03:38:49 < upgrdman> i don't think i have any way to measure something very hot. i have only cheap IR temp gun (not good due to emissivity) and a cheap meat thermometer.
2014-11-01T03:39:09 < BrainDamage> use meat thermometer and don't integrate for long time
2014-11-01T03:39:13 < BrainDamage> say, 60s
2014-11-01T03:39:18 < BrainDamage> or less
2014-11-01T03:39:43 < upgrdman> k
2014-11-01T03:40:34 < BrainDamage> try also to insulate the test rod with some packing material, say polystirene ( hoping it won't melt ), to reduce convection and radiation losses
2014-11-01T03:41:13 < upgrdman> :( wish i had a yard or garage to do this kinda stuff in. don't want to risk a fine in the bedroom.
2014-11-01T03:41:20 < upgrdman> s/fine/fire
2014-11-01T03:41:28 < BrainDamage> rock wool then
2014-11-01T03:41:46 < BrainDamage> good luck setting that on fire
2014-11-01T03:43:05 < BrainDamage> the rod thickness will be a bit of a tradeoff, ideally a physically large rod allows you to have lower temps, and slows everything due to having a large thermal capacity, at the same time, you'll see uneven heating dur to finite conducibility ( external part will warm up before the inner ), so assuming the whole material at same T for total energy would be wrong
2014-11-01T03:43:41 < upgrdman> your brain doesn't seem too damaged. have a background in physics?
2014-11-01T03:45:53 < BrainDamage> I'm an EE, but I had a decent fraction of physics for both personal interest and ic design
2014-11-01T03:47:21 < BrainDamage> oh a personal suggestion: if you see the coupling efficiency being bad, try increasing the switching frequency, you'll lose more power on the mos and the mos drivers, but you'll gain better coupling because the material will become more resistive due to skin depth getting smaller
2014-11-01T03:48:08 < upgrdman> ya. i read that higher freqs -> skin gets hotter quicker, lower freqs -> more even heating throughout
2014-11-01T03:49:37 < upgrdman> right now i can't really adjust freq. using a very simple oscillator circuit, just diodes between gates that are pulled up.
2014-11-01T03:49:51 < upgrdman> i'd have to change coil or caps.
2014-11-01T03:50:03 < BrainDamage> also do try shit iron, having an high mu_r it should couple very well
2014-11-01T03:50:18 < BrainDamage> like some rebar rod chunk
2014-11-01T03:50:23 < upgrdman> k
2014-11-01T03:50:29 < BrainDamage> or magnetic steel
2014-11-01T03:50:34 < upgrdman> i tried a cheap screw driver. it glows orange.
2014-11-01T03:51:30 < upgrdman> and there's a point where it starts to require a lot more power to heat it. i think that's the curie point? where magnetic hysteresis no longer contributes to the heating.
2014-11-01T03:52:08 < upgrdman> cold screwdriver: 25A flows with only 4V. when it starts to glow: 25A flows with 15V.
2014-11-01T03:52:37 < emeb_mac> wow - resistance is a function of temperature. who knew?
2014-11-01T03:53:03 < upgrdman> not talking about that.
2014-11-01T03:53:26 < upgrdman> magnetic hysteresis helps a LOT with induction heating.
2014-11-01T03:54:35 < upgrdman> "Magnetic materials improve the induction heat process because of hysteresis. Materials with high permeability (100–500) are easier to heat with induction heating. Hysteresis heating occurs below the Curie temperature where materials retain their magnetic properties. High permeability below the Curie temperature in the workpiece is useful. Temperature difference, mass, and specific heat influence the workpiece heating."
2014-11-01T03:54:57 < scummos> > ya. i read that higher freqs -> skin gets hotter quicker, lower freqs -> more even heating throughout --- << yes, for frequencies in the gigaherz range and water-based substances that is true
2014-11-01T03:55:11 < BrainDamage> not just GHz
2014-11-01T03:55:25 < scummos> because water has a very broad absorption line around 22 GHz and the closer you get to that the better it absorbs the radiation
2014-11-01T03:55:42 < BrainDamage> try to do the calculation for shit iron of skin depth at mere 10MHz, you'll get few um
2014-11-01T03:56:28 < BrainDamage> also, those are conduction losses, water losses at high freq are dielectric polarization losses
2014-11-01T03:56:52 < scummos> yes, true, the effect I was referring to is something entirely different than the skin effect
2014-11-01T03:56:57  * scummos apologizes for not reading backlog

2014-11-01T07:39:31 < ossifrage> Any ideas how to convince gcc not to complain about 'unsigned int' vs 'uint32_t', when checking printf style format strings (I'd rather have "%u" vs "%lu" in the code)
2014-11-01T07:39:45 < ossifrage> I am never going to try and port this code to a 64 bit machine...
2014-11-01T07:39:59 < madiz> there should be a pragma to turn off that particular warning
2014-11-01T07:40:23 < ossifrage> display.c:90:5: warning: format '%u' expects argument of type 'unsigned int', but argument 2 has type 'uint32_t' [-Wformat=]
2014-11-01T07:40:24 < madiz> turn it off just before your code and turn it back on after.
2014-11-01T07:40:58 < ossifrage> I want format checking, I jut don't need to care about playing nice between 32 bit and 64 bit...
2014-11-01T07:41:40 < madiz> #pragma GCC diagnostic ignored "-Wformat"
2014-11-01T07:42:02 < madiz> that's a bit too specific I think.
2014-11-01T07:42:05 < ossifrage> madiz, yeah, that kills all format checking, format checking is good
2014-11-01T07:42:27 < madiz> ossifrage: that's why I said turn it off just before the offending code and restore it afterward.
2014-11-01T07:42:54 < ossifrage> That would be almost every printf, the entire code is filled with uint32_t
2014-11-01T07:43:14 < madiz> why is %u preferable to %lu ?
2014-11-01T07:43:44 < ossifrage> (fewer bytes)
2014-11-01T07:43:49 < ossifrage> [duck]
2014-11-01T07:44:08 < upgrdman> madiz: http://www.tayloredge.com/museum/mymuseum/electronics/deadbug.jpg
2014-11-01T07:44:08 < madiz> they're the same size
2014-11-01T07:44:12 < madiz> signed vs unsigned
2014-11-01T07:44:20 < ossifrage> fewer bytes in the format string
2014-11-01T07:44:37 < ossifrage> and printf doesn't have to do extra work on it
2014-11-01T07:44:49 < madiz> upgrdman: it says permission denied
2014-11-01T07:45:02 < upgrdman> wat
2014-11-01T07:45:08 < madiz> hmm and now it loads
2014-11-01T07:45:13 < madiz> strange
2014-11-01T07:45:40 < ossifrage> I was hoping there was a way to convince the compiler that 'unsigned int' and 'uint32_t' are the same.
2014-11-01T07:46:56 < ds2> Add -Duint32_t="unsigned int"?
2014-11-01T07:47:06 < madiz> hehehe
2014-11-01T07:47:12 < ossifrage> ds2, ouch
2014-11-01T07:47:26 < ossifrage> Like '-D0=1'
2014-11-01T07:47:42 < upgrdman> #define true false
2014-11-01T07:47:50 < madiz> I've seen code in a large commercial project that had #define private public
2014-11-01T07:48:21 < madiz> this software sold for a 6 figure price
2014-11-01T07:49:17 < ossifrage> I was hoping there was an old legacy option, this code will never target anything but a 32-bit chip and all the '%lu' annoy me even though it is the portable way to do it
2014-11-01T07:49:43 < ossifrage> It wouldn't bother me at all on a 64 bit machine or at least an arch that has the chance of being 64 bit
2014-11-01T07:50:00 < madiz> write your code with %u and then hire a freelancer on odesk to rewrite all the %u's to %lu.
2014-11-01T07:50:19 < ds2> after a full day of battling with Keil...
2014-11-01T07:50:21 < ossifrage> Yeah I guess I'll stick with the %lus
2014-11-01T07:50:37 < ds2> I suppose you can run it thru sed
2014-11-01T07:50:47 < ossifrage> This is gcc thankfully
2014-11-01T07:51:21 < ossifrage> Oh, the other day I found a really awesome doh, with lto..
2014-11-01T07:51:32 < ds2> gcc should understand typedefs
2014-11-01T07:52:25 < ossifrage> I had a symbol bound to a second with the section attribute: something like const blah_t bla __attribute__((section(".blah")));
2014-11-01T07:52:57 < ossifrage> But that .blah section was something from the bootloader.
2014-11-01T07:53:25 < ossifrage> The compiler saw const, decided the section was zero-filled and then optimized all the code using it away (treating it all as zeros)
2014-11-01T07:53:30 < madiz> what is lto ?
2014-11-01T07:53:32 < ossifrage> Was quite the head scratcher
2014-11-01T07:53:40 < ossifrage> link time optimizer (-flto)

2014-11-01T23:29:54 < zyp> one of my friends got a nokia winphone

2014-11-01T23:38:10 < zyp> I currently have a nexus 4 that I'm happy with
2014-11-01T23:38:43 < zyp> I've never owned a winphone or an iphone, so I can't really hold an informed opinion about whether I'd like them or not
2014-11-01T23:39:30 < zyp> given that it's produced by LG, I don't think it's worth sending it to samsung for repair
2014-11-01T23:40:12 < zyp> are you sure it's a nexus 4?
2014-11-01T23:40:22 < zyp> the galaxy nexus was samsung
2014-11-01T23:41:28 < zyp> considering it's three generations old, I don't really think it's worth spending a lot on repairs
2014-11-01T23:41:57 < zyp> you could probably pick up another galaxy nexus for cheaper if you'd prefer to stay with that model
2014-11-01T23:42:26 < zyp> unsure
2014-11-01T23:42:45 < qyx_> i heard that according to some stats win phone users are even happier than iphone users
2014-11-01T23:42:53 < zyp> nexus 4 isn't available anymore anyway
2014-11-01T23:42:53 < qyx_> although i dont really know what "happier" means
2014-11-01T23:43:04 < zyp> nexus 5 should be, and is fairly cheap
2014-11-01T23:43:24 < zyp> nexus 6 was going to be more expensive from what I heard
2014-11-01T23:44:16 < zyp> also, I have a less than favorable impression of the nexus 6 so far
2014-11-01T23:44:24 < zyp> it looks too big and bulky
2014-11-01T23:44:38 < zyp> not $200?
2014-11-01T23:45:03 < zyp> oh, ok
2014-11-01T23:45:18 < zyp> yeah, you're right, I'm mixing currencies
2014-11-01T23:45:25 < zyp> eh
2014-11-01T23:45:57 < zyp> considering the speed of development in phones they don't last very long anyway
2014-11-01T23:46:00 < zyp> oh
2014-11-01T23:46:02 < zyp> shame
2014-11-01T23:46:47 < zyp> I didn't say that
2014-11-01T23:48:33 < zyp> I don't think so
2014-11-01T23:48:51 < zyp> I bought my nexus 4 from a norwegian store, and I still get updates fairly early
2014-11-01T23:49:07 < zyp> of course
2014-11-01T23:50:15 < zyp> don't have any notable experiences
2014-11-01T23:51:09 < zyp> I mainly said it's cheaper
2014-11-01T23:51:20 < zyp> so it might be better value for money
2014-11-01T23:51:38 < zyp> I don't like the idea of the size of the nexus 6
2014-11-01T23:52:05 < zyp> but considering much of the additional volume is spent on a fairly larger battery, it might be worth it if you care about battery life
2014-11-01T23:53:50 < zyp> me too
2014-11-01T23:54:08 < zyp> I don't really know what I'd choose
2014-11-01T23:54:20 < zyp> thankfully I still have a phone that I'm happy with
2014-11-01T23:54:52 < zyp> so I just hope there will be a more interesting model available before I break my nexus 4 :p
2014-11-01T23:56:13 < zyp> no idea
2014-11-01T23:56:32 < zyp> norwegian consumer protection law entitles me to at least two years anyway, so that doesn't matter
2014-11-01T23:57:11 < zyp> or maybe it's five years, I'm not sure which category phones go into
2014-11-01T23:57:49 < zyp> ah, it's five years on phones
2014-11-01T23:58:02 < zyp> so a one-year warranty is completely irrelevant to me
2014-11-01T23:58:24 < zyp> no, of course not
2014-11-01T23:58:39 < zyp> I mean, it just covers manufacturer defects
2014-11-01T23:59:28 < zyp> maybe, depends what the cause is
--- Day changed Sun Nov 02 2014
2014-11-02T00:01:31 < zyp> I don't care about protection plans, in my experience it's not worth it
2014-11-02T00:02:40 < zyp> well, it's like an insurance
2014-11-02T00:03:19 < qyx_> you can buy two!
2014-11-02T00:03:22 < zyp> in the long run, you lose money on it because the company issuing the insurance need to make money on it
2014-11-02T00:04:42 < zyp> monitor would be covered anyway for me, unless I break it myself
2014-11-02T00:04:49 < zyp> of course it is
2014-11-02T00:04:56 < zyp> people break smartphones all the time
2014-11-02T00:05:10 < zyp> insurance is expensive when the risk is high
2014-11-02T00:06:27 < zyp> and the people buying insurance is probably going to be extra careless too, since they're insured
2014-11-02T00:07:17 < zyp> so even if you're careful with your phone, buying insurance means you're wasting money paying for people that's not as careful :p

2014-11-02T00:54:23 < zyp> dunno
2014-11-02T00:55:23 < qyx_> it is normal OTG port
2014-11-02T00:55:35 < qyx_> you can use serial->usd adapter for example
2014-11-02T00:55:37 < qyx_> or usb wifi
2014-11-02T00:55:39 < qyx_> or usb ethernet
2014-11-02T00:55:51 < zyp> nexus 4 misses circuitry for providing vbus, so it's not OTG capable
2014-11-02T00:55:52 < qyx_> just buy OTG microusb to usb adapter cable
2014-11-02T00:55:59 < qyx_> how so?
2014-11-02T00:56:05 < zyp> but I believe nexus 5 is
2014-11-02T00:56:15 < qyx_> i am quite sure it has
2014-11-02T00:56:18 < qyx_> at least mine in work
2014-11-02T00:56:28 < qyx_> it works tẃith usb keyboard
2014-11-02T00:56:48 < zyp> with appropriate permissions
2014-11-02T00:57:02 < zyp> OTG means that it can acts as a USB host
2014-11-02T00:57:37 < zyp> hmm, you also have that special android thing for phones that's not OTG-capable
2014-11-02T00:57:51 < zyp> but that requires a host-capable device in the other end
2014-11-02T00:59:45 < zyp> don't ask me, I don't make apps
2014-11-02T00:59:52 < qyx_> check "adt bundle"
2014-11-02T00:59:55 < qyx_> android development tools
2014-11-02T01:00:01 < qyx_> its eclipse packet with other stuff
2014-11-02T01:00:06 < qyx_> *packed
2014-11-02T01:00:43 < qyx_> i suggest you to search on google's sites instead of ms..
2014-11-02T01:01:03 < qyx_> https://developer.android.com/tools/index.html
2014-11-02T01:01:47 < qyx_> or use xamarin with c#
2014-11-02T01:03:04 < qyx_> or android studio, but never worked with that
2014-11-02T01:03:06 < qyx_> it is still beta
2014-11-02T01:04:19 < qyx_> probably
2014-11-02T01:06:09 < qyx_> i would say java as it is nativa platform for android apps
2014-11-02T01:06:16 < qyx_> either dalvik vm or ART

2014-11-02T10:03:53 < upgrdman> anyone know what the purpose of brake pad shims are? it's not like the pad thickness is critical, it becomes several mm thinner as the pad wears.
2014-11-02T10:06:32 < englishman> usually anti-rattle
2014-11-02T10:06:49 < englishman> they can also have some adhesive for anti-squeal
2014-11-02T10:08:25 < upgrdman> how do they prevent rattle?
2014-11-02T10:08:39 < upgrdman> or squeal for that matter
2014-11-02T10:09:28 < englishman> they keep pressure on the pad
2014-11-02T10:09:59 < englishman> the adhesives reduces vibration or something
2014-11-02T10:10:50 < upgrdman> the shims on my pads aren't springy. they just sit on the pad. are most springy?
2014-11-02T10:11:56 < englishman> just a flat piece of metal?
2014-11-02T10:12:12 < englishman> they deform a bit after a while and cause the springiness
2014-11-02T10:12:14 < englishman> or something
2014-11-02T10:14:13 < upgrdman> ya. a stamped sheet, with three fingers the grip the sides of the pad

2014-11-02T14:12:15 < effractur> if you have a good compiler it will create a SIMD version from the scaler version
2014-11-02T14:12:39 < AndreeeCZ> effractur, mine doesn't (gcc)
2014-11-02T14:13:14 < effractur> default gcc does not do that
2014-11-02T14:13:20 < effractur> you have to give the correct compiler flags
2014-11-02T14:13:49 < effractur> but i think the simd is faster
2014-11-02T14:14:20 < AndreeeCZ> effractur, even if the vector size is 2?
2014-11-02T14:14:37 < effractur> compile the scaler with -mfpu=neom
2014-11-02T14:14:38 < effractur> neon*

2014-11-02T14:15:05 < AndreeeCZ> i use cortex m4
2014-11-02T14:15:29 < effractur> well look the -march flags for your chip and use them in gcc
2014-11-02T14:15:43 < effractur> AndreeeCZ: you can build a small benchmark
2014-11-02T14:15:50 < effractur> to see what is faster
2014-11-02T14:16:38 < AndreeeCZ> well, i use -mcpu=cortex-m4
2014-11-02T14:16:58 < AndreeeCZ> i also see in objdump that arm_***_f32() has over 100 lines
2014-11-02T14:17:27 < AndreeeCZ> my assembly skills are not good enough to see what exactly is going on there
2014-11-02T14:18:28 < effractur>  -march
2014-11-02T14:18:57 < effractur> see

2014-11-02T17:17:49 < Getty> dongs: would just like to discuss that a bit, if its possible :) USB spec is REALLY hardcore, i mean alone understanding what USB you have on a device and stuff so many diffs
2014-11-02T17:18:20 < Tectu_> dongs, What interface is between the PHY and your MCU?
2014-11-02T17:19:11 < zyp> Tectu_, he probably used FX3 with a built in PHY
2014-11-02T17:19:25 < Getty> cool i understand the question AND the answer ;)
2014-11-02T17:20:07 < zyp> Tectu_, discrete USB3 PHYs apparently use the PIPE-interface
2014-11-02T17:20:32 < zyp> with 16-bits for data in each direction and a ton of of control signals
2014-11-02T17:21:18 < Tectu_> zyp, interesting. So when using that FX3 you don't have to implement "the usb stack" or what it is called yourself? You can simply tell it to "send 0x0FF to my bloody USB device" ?
2014-11-02T17:21:29 < Getty> what i want to make is an USB "router", so you can attach several Hosts and several clients and software says which device from the clients talks to with host
2014-11-02T17:21:46 < zyp> for FX3 you probably get a full stack that you just add descriptors and shit to

2014-11-02T17:23:06 < zyp> USB isn't designed to work with more than one host
2014-11-02T17:23:21 < Tectu_> zyp, interesting. thanks for the insights.
2014-11-02T17:23:31 < zyp> Tectu_, I just looked it up myself
2014-11-02T17:23:49 < Tectu_> I've never bothered doing anything with USB beside using the CDC on the USB fullspeed peripheran on an F4
2014-11-02T17:26:26 < Getty> zyp: wait wait, i really tlak router, itsnot like i just "link them all together"
2014-11-02T17:27:09 < Getty> zyp: the idea is to mae it like a proxy, that whatever connects on the "client side" gets then reflected on the "host side" where it is supposed to be connected to

2014-11-02T17:27:53 < zyp> I still maintain that it's a bad idea
2014-11-02T17:28:33 < Getty> well can you be more detailed to make me so wise that i also see why its a bad idea? :) i mean the main reason is here for usability, _I_ need that stuff and many people want that too i think, software based USB routing
2014-11-02T17:29:04 < Getty> but yeah, not finding a solution n the market yet, made me think that it MIGHT be really impossible ;) but "bad idea" sounds not impossible ;-)
2014-11-02T17:29:34 < zyp> well, first consider how realistic it would be to make something like that
2014-11-02T17:30:05 < zyp> you'd have to make a device that could emulate multiple devices to multiple hosts and then acts as a host for downstream devices aswell
2014-11-02T17:30:16 < Getty> exactly :) that describes it
2014-11-02T17:30:20 < dongs> Getty: i just used ezusbfx3
2014-11-02T17:30:52 < dongs> (yea wat zyp said)
2014-11-02T17:31:03 < zyp> Getty, as far as I know there's no chip on the market that can do something like that, so you'd have to implement most of it in an FPGA or something
2014-11-02T17:31:19 < Getty> zyp: ok then lets go back, this why nots not possible interest me
2014-11-02T17:31:40 < Getty> zyp: it sounds like.... the USB "thing" in the device can always be "just one"?
2014-11-02T17:31:57 < zyp> what do you mean?
2014-11-02T17:32:16 < Getty> zyp: so like... when i am a fake-usb-keyboard... i cant be 2 fake-usb-keyboard at once, if i just have "1 usb" on my usb-chip/solution?
2014-11-02T17:33:12 < zyp> that's not the point
2014-11-02T17:33:37 < zyp> you need one port towards each host you're going to talk to, and one port towards the devices
2014-11-02T17:33:46 < Getty> yeah right
2014-11-02T17:33:50 < Getty> lets imagine we do that
2014-11-02T17:33:52 < zyp> so first of all you need three ports for it to be a point at all
2014-11-02T17:34:00 < Getty> yeah sure
2014-11-02T17:34:08 < Getty> exactly
2014-11-02T17:34:25 < Getty> i am aware of this, i already thought about "1 ARM per USB in/out" and just link them all
2014-11-02T17:34:41 < Getty> but there i thought "how to they communicate on that speed level 8-)"
2014-11-02T17:34:44 < zyp> then again, if you want to have multiple downstream devices, you need to be able to emulate a hub, which means that your upstream ports need to be able to accept traffic for multiple addrs at once
2014-11-02T17:34:58 < dongs> Getty: if youre wasting your time, you migth wanna look into some other custom USB3 thing, a USB3 upstream port that accepts real USB2 devices and translates usb2 into usb3 upstream
2014-11-02T17:34:59 < zyp> normally usb device controllers only accept traffic for one device at a time
2014-11-02T17:35:14 < dongs> so you can have liek 10 USB2 devices off a usb3 port sharing bandwidth
2014-11-02T17:35:24 < Getty> zyp: yeah ok but lets go "big" here and think we really have one chip per USB in/out
2014-11-02T17:35:27 < dongs> insetead of the current idiocy where each usb3 port is just wasted for usb2 on different pins
2014-11-02T17:35:38 < Getty> zyp: so for every usb port we got one, and for every usb client port we got one
2014-11-02T17:35:38 < zyp> Getty, that's irrelevant
2014-11-02T17:35:49 < Getty> yeah ok, just saying :)
2014-11-02T17:36:11 < zyp> dongs, does usb3 spec even include traffic translation?
2014-11-02T17:36:44 < dongs> zyp, no but its been done
2014-11-02T17:36:48 < dongs> by some chinks who never a nswered me

2014-11-02T17:37:20 < Getty> ok lets just go down to the most simple case and lets see where the problem is there, ok? that might help me getting the core points of the impossible
2014-11-02T17:37:21 < zyp> dongs, usb2 has special support for proxying FS/LS traffic over a HS connection, you can't really proxy HS traffic over SS if there isn't any protocol for it
2014-11-02T17:37:34 < Getty> lets imagine we just have like 1 USB Host and 1 USB Client and we are the "thing" in between
2014-11-02T17:37:55 < Getty> so we make a "thing" that takes in 1 USB Host (so emulates a client there) and takes in 1 USB client (so emulates a host there)
2014-11-02T17:38:07 < zyp> Getty, that's not a problem
2014-11-02T17:38:41 < Getty> so we could make that "thing" so that it says "i just pass through THIS usb device, all others who you connect i would ignore"
2014-11-02T17:39:11 < Getty> so that it minimal processes them by checking what USB client device is it, before it passes it through
2014-11-02T17:39:23 < Getty> thats doable?
2014-11-02T17:39:26 < zyp> you could probably make a simple crossbar switchboard if that's what you want
2014-11-02T17:40:55 < Getty> you mean like mechanical? ;) hand routing? ;)
2014-11-02T17:41:01 < zyp> no
2014-11-02T17:41:37 < zyp> say you have four hosts, and want to connect four devices
2014-11-02T17:41:46 < Getty> ok
2014-11-02T17:43:00 < zyp> so you make a pcb with a hub controller chip for each host, then connect each port of each host together in a demux-topology so that each of the downstream ports can be connected to one of the hub chips at a time
2014-11-02T17:43:28 < zyp> then you have a microcontroller for controlling the demuxers
2014-11-02T17:43:45 < zyp> that way the microcontroller will be able to control which host each port is connected to
2014-11-02T17:43:53 < Getty> ah ok, and thats then doable without relais?
2014-11-02T17:44:08 < Getty> i check into demux
2014-11-02T17:44:09 < zyp> of course
2014-11-02T17:44:53 < zyp> http://www.nxp.com/documents/data_sheet/NX3DV221.pdf <- for usb2 you could use something like this
2014-11-02T17:51:16 < Getty> but this chip is now specific USB 2.0, but that demux is a general thing, right?
2014-11-02T17:51:39 < zyp> it's not specific, it's just fast enough to deal with USB2 signals
2014-11-02T17:51:53 < Getty> ah ok, get it, so they named it so ;)
2014-11-02T17:52:16 < Getty> ah, so thats the difference to relais, slowly getting stuff

2014-11-02T18:31:09 < Getty> dongs: a lot of little reasons, most big one is remote electronic development workstation
2014-11-02T18:31:28 < Getty> (so switching programmers between devices without being physical there)
2014-11-02T18:31:43 < Getty> or whatever things...
2014-11-02T18:31:53 < dongs> well, okay. valid reason i guess.
2014-11-02T18:32:10 < Getty> i think what animates me most to think about this topic is that its not there
2014-11-02T18:32:39 < Getty> ;)
2014-11-02T18:32:56 < Getty> or i didnt found one so far its HARD to seek for that
2014-11-02T18:36:26 < dongs> well, switch is what you would use. that, and some stuff to connect/disconnect power as well
2014-11-02T18:36:40 < dongs> so you could reboot devices by killing them power

2014-11-02T19:42:54 < englishman> you have never seen the welding masks they wear?
2014-11-02T19:43:20 < TheSeven> hm... how do I get the OTG FS clock right with an f107 with a 25MHz xtal?
2014-11-02T19:44:42 < bvernoux> TheSeven: maybe you should use a 8MHz crystal
2014-11-02T19:45:15 < TheSeven> bvernoux: the thing is that (at least according to the datasheets) the USB DFU bootloader can run with a 25MHz, so it must be possible...
2014-11-02T19:45:26 < bvernoux> ha ok
2014-11-02T19:45:37 < bvernoux> it depends on the PLL inside
2014-11-02T19:45:41 < TheSeven> however I fail to see how it manages to do so
2014-11-02T19:46:09 < TheSeven> the clock tree can divide by /1.../16 and then multiply by x4...x9 or x6.5
2014-11-02T19:46:17 < TheSeven> to use USB the output must be 48MHz or 72MHz
2014-11-02T19:46:51 < TheSeven> the divided frequency must be between 3 and 12 MHz

2014-11-02T19:48:14 < bvernoux> very limited PLL ;)
2014-11-02T19:48:27 < TheSeven> well, f1 series...
2014-11-02T19:48:32 < TheSeven> on f2/f4 it's easy
2014-11-02T19:49:00 < bvernoux> why so many people are stuck to those F1 ?
2014-11-02T19:49:12 < bvernoux> I really do not understand except maybe price lower ...
2014-11-02T19:49:36 < TheSeven> the f107 is more expensive than the f205 equivalent
2014-11-02T19:49:39 < bvernoux> some STM32F3 are very cheap too and with F4 and similar feature as high end F4
2014-11-02T19:50:26 < TheSeven> the thing is that I need ethernet in a 64 pin package, and f107 is the only one which is available in that combination
2014-11-02T19:51:00 < TheSeven> I can just use an F205 which doesn't officially support ethernet (but it seems to work regardless)
2014-11-02T19:51:14 < TheSeven> but I kinda want to have the F107 as a backup plan ;)

2014-11-02T19:55:46 < bvernoux> ethernet on F1 is probably limited to 10Mbits/s
2014-11-02T19:56:00 < TheSeven> huh? why that?
2014-11-02T19:56:12 < bvernoux> because of limited power of F1
2014-11-02T19:56:19 < bvernoux> ;)
2014-11-02T19:56:47 < bvernoux> ha up to 72MHz
2014-11-02T19:57:22 < bvernoux> but I imagine how it is slow executing from flash ... without the feature of modern MCU F3/F4
2014-11-02T19:58:08 < kakeman> gigabit for the win
2014-11-02T19:58:40 < bvernoux> kakeman: I would love to see gigabit Eth on MCU ;)
2014-11-02T19:59:05 < bvernoux> would be a must for realtime stuff ;)
2014-11-02T20:00:18 < kakeman> that's why
2014-11-02T20:00:27 < kakeman> better than usb
2014-11-02T20:00:52 < bvernoux> yes simpler and better than USB
2014-11-02T20:01:06 < kakeman> but still too slow for some applications
2014-11-02T20:01:19 < bvernoux> not for MCU even F7 ;)
2014-11-02T20:02:03 < TheSeven> so... how do I derive a 48MHz clock? ;)
2014-11-02T20:03:19 < bvernoux> TheSeven:  you cannot with your limited PLL
2014-11-02T20:03:26 < bvernoux> TheSeven: move to a 8MHz crystal
2014-11-02T20:03:37  * TheSeven wonders if they just overclock it to 75MHz instead of 72 in the bootloader

2014-11-03T05:21:16 < dongs> and no, i dont have my shit anymore, my 3tb crapdrive shit itself so all temporary junk that was there is gone
2014-11-03T05:22:22 < upgrdman> dongs: latest firmwar, 2.3.0. it's been hacked.
2014-11-03T05:22:42 < dongs> cool
2014-11-03T05:22:54 < dongs> im still on 1.19 or wahtever
2014-11-03T05:22:57 < dongs> not that i care
2014-11-03T05:23:42 < upgrdman> was trivial to hack too. basically you load a FIF to set RNDIS mode. then get the camera's ip with ipconfig, run a python script some guy wrote, hard reset he camera. done.
2014-11-03T05:28:30 < dongs> yeah, it was similar with old firmware
2014-11-03T05:28:42 < dongs> i guess the new 'unhack' stuff is just more encryption that was already reversed by now.
2014-11-03T05:28:58 < upgrdman> was kinda freaky to see my thermal reflection in a mirror in my pitch black bedroom.
2014-11-03T05:29:29 < zyp> how much were that shit?

2014-11-03T05:29:54 < upgrdman> zyp: $1000 retail. less if you look around.
2014-11-03T05:29:56 < dongs> SiZn or wahtever lens

2014-11-03T07:03:48 < amstan> upgrdman: i was just playing with the lepton
2014-11-03T07:19:44 < upgrdman> :) its more of a toy for me. bought it because i wanted to monitor temps of some PCB components more easily than a stack of thermocouples.
2014-11-03T07:20:26 < upgrdman> a lot of my projects are "fabricated" instead of "engineered" so keeping an eye on temps in key. that, and a cv/cc bench supply.
2014-11-03T07:20:31 < upgrdman> R2COM: got my flir r4.
2014-11-03T07:20:35 < upgrdman> http://www.farrellf.com/temp/thermal_image_dinner.jpg
2014-11-03T07:21:28 < upgrdman> use it to keep an eye on component temps for various projects.
2014-11-03T07:21:36 < upgrdman> like the capactiors of my induction heater.
2014-11-03T07:23:13 < upgrdman> i think this e4 is gonna be like my lcr meter. don't need it very often, but when you do it should save lots of time.
2014-11-03T07:27:41 < upgrdman> also replaced my car's front brake pads and rotors.
2014-11-03T07:27:57 < upgrdman> sore back :( but no more squeaky brakes :)
2014-11-03T07:28:20 < upgrdman> you paid someone to do it, or you did it?
2014-11-03T07:28:42 < upgrdman> to save like $300 ?
2014-11-03T07:28:50 < upgrdman> and spend that $300 on toys.
2014-11-03T07:30:00 < upgrdman> *more toys
2014-11-03T07:30:01 < upgrdman> :)
2014-11-03T07:30:09 < upgrdman> sure
2014-11-03T07:33:50 < upgrdman> why?
2014-11-03T07:34:09 < upgrdman> as in, why when you're far away?
2014-11-03T07:34:24 < upgrdman> ya. that's what key fobs with engine start are for.
2014-11-03T07:34:32 < upgrdman> range of ~100ft
2014-11-03T07:35:00 < upgrdman> that's actually something i want when i get a new car. key fob with engine start button.
2014-11-03T07:35:20 < upgrdman> R2COM: you want the engine to idle for an hour while you trek to your car?
2014-11-03T07:43:39 < zyp> isn't phone apps and internet enabled cars the thing nowadays?
2014-11-03T07:44:12 < zyp> not mine either, but it's fucking old
2014-11-03T07:44:17 < upgrdman> R2COM: hmm. i bet some of the kids in ##arduino have done it. an arduino, gsm shield, and a poorly wrriten "sketch" should do the trick :)
2014-11-03T07:44:28 < upgrdman> and a relay wired into your car.

2014-11-03T07:47:40 < zyp> say, are your cars automatic or manual transmission?
2014-11-03T07:48:00 < zyp> «of course»
2014-11-03T07:48:13 < zyp> you say it like it's obvious
2014-11-03T07:49:39 < zyp> does the «of course» mean you live in a part of the world where drivers are considered too dumb to be trusted to shift gears themselves?
2014-11-03T07:51:08 < zyp> right
2014-11-03T07:52:03 < englishman> pushbutton start? keyfob? sooo 90s
2014-11-03T07:52:11 < englishman> this was my car over 10 years ago http://i.imgur.com/sqJmwIZ.jpg
2014-11-03T07:52:13 < upgrdman> i always wanted to learn how to drive a manual transmission. never got a chance :(
2014-11-03T07:52:17 < englishman> with rfid door + secutiry
2014-11-03T07:52:22 < englishman> security
2014-11-03T07:52:23 < zyp> heh
2014-11-03T07:52:45 < upgrdman> englishman: no air bag?
2014-11-03T07:52:50 < englishman> ha
2014-11-03T07:53:13 < zyp> I've driven a lot of cars, but only four of them was automatic
2014-11-03T07:53:17 < upgrdman> "don't worry, the windshield will brake your fall"
2014-11-03T07:53:20 < englishman> whats the point of an airbag when the sheetmetal car would kill me inside of it
2014-11-03T07:53:31 < upgrdman> k
2014-11-03T07:54:15 < zyp> so the concept of manual transmissions being hard to drive is pretty unfamiliar to me
2014-11-03T07:54:49 < zyp> anyway
2014-11-03T07:55:11 < englishman> R2COM: should i buy a lada niva
2014-11-03T07:55:31 < zyp> what led me into this line of thought was the fact that manuals don't have a dedicated park-mode, you normally leave it in 1st
2014-11-03T07:55:40 < zyp> which would be pretty dangerous with remote start
2014-11-03T07:55:58 < englishman> needs to be 15 yers old to import :(
2014-11-03T07:56:11 < zyp> I always use both
2014-11-03T07:56:17 < zyp> redundancy you know
2014-11-03T07:56:40 < englishman> zyp the commercial remote start shits make you lock the door with the motor running, so it knows it will be in neutral
2014-11-03T07:56:56 < upgrdman> zyp: the overall concept of a manual seems easy enough. i just lack any experience and would likely stall a lot, mis shift, and maybe have problems going up hill from a stand still
2014-11-03T07:57:10 < zyp> englishman, ah, right
2014-11-03T07:57:11 < englishman> that stuff takes you 5 minutes to learn
2014-11-03T07:57:29 < zyp> upgrdman, yes, that is all very true
2014-11-03T07:57:40 < upgrdman> probably. but i wouldn't want to learn it at the dealership on a test drive :)
2014-11-03T07:57:48 < englishman> what, thats what theyre for
2014-11-03T07:59:05 < upgrdman> how long do you guys often keep your cars for? mine is 9yrs old and im tempted to upgrade in 3 - 5 years.
2014-11-03T08:00:16 < englishman> yes reminds me of unimog
2014-11-03T08:00:23 < zyp> I think mine is 23 years or so
2014-11-03T08:00:56 < upgrdman> mine is 9yrs old, 140k miles, still dependable. but i want some of the conveniences of a newer car, and don't feel like retrofitting them into an older car. remote engine start, audio in jack, bluetooth audio, etc.
2014-11-03T08:01:17 < upgrdman> plus my paint job is starting to look like shit.
2014-11-03T08:01:28 < upgrdman> and don't want to pour money into a 9yr old car
2014-11-03T08:01:46 < zyp> I got mine off my parents when they replaced it six years ago
2014-11-03T08:02:01 < englishman> what car upgrdman
2014-11-03T08:02:08 < upgrdman> 2005 toyota celica
2014-11-03T08:02:19 < englishman> automatic
2014-11-03T08:02:24 < upgrdman> "of course"
2014-11-03T08:02:28 < englishman> of course
2014-11-03T08:02:35 < englishman> yeah not a whole lot of resale value in that.
2014-11-03T08:02:39 < upgrdman> ya
2014-11-03T08:02:45 < upgrdman> and it runs very well.
2014-11-03T08:02:47 < englishman> drive it til it dies then worry about spending money
2014-11-03T08:02:53 < zyp> I'm thinking that I'll keep driving it until it dies, no point in replacing something that works
2014-11-03T08:02:54 < upgrdman> so i feel bad selling it for pennies

2014-11-03T16:42:04 < karlp> that's how I do it, works just fine and dandy
2014-11-03T16:42:10 < dongs> ok
2014-11-03T16:42:21 < dongs> i guess i  won't get TXNE irq unless i enable it
2014-11-03T16:42:24 < dongs> so i dont need to care for it
2014-11-03T16:42:28 < karlp> rx irq into a ring, tx is dma'd in blocks
2014-11-03T16:43:08 < Laurenceb_> actually
2014-11-03T16:43:14 < Laurenceb_> i have a project that does that too
2014-11-03T16:43:19 < Laurenceb_> heh i forgot
2014-11-03T16:47:41 < Lux> any ideas where i can get a 4 terminal shunt resistor with a very low thermal coefficient ?

2014-11-03T19:23:45 < qyx_> wat
2014-11-03T19:24:01 < qyx_> pd5 is connected to led8 according to F4 discovery manual
2014-11-03T19:24:28 < qyx_> so i suppose PD5 is working perfectly if led8 is lit
2014-11-03T19:25:35 < Jamshoot> google says that ld8 is for USB over-current

Setting 29 bit to RCC_APB1ENR;  5, 4, 3, 2, 0 bits to DAC_CR (TSEL1 is 111 bits, software trigger; TEN1 is 1; then EN1 is 1 to enable shit); Setting data to DAC_DHR12R1 (0x400). Try to set  DAC_SWTRIGR to 1 and nothing happends. DAC_SWTRIGR is 0 and  DAC_DOR1 is 0 too (i belive it must be 0x400 as DHR12R1)
2014-11-03T22:43:03 < bvernoux> Jamshoot: maybe just try using STM32Cube F4 HAL/Driver
2014-11-03T22:43:12 < Tectu_> Jamshoot, what bvernoux said
2014-11-03T22:43:39 < bvernoux> easier at start to understand how that work
2014-11-03T22:44:06 < bvernoux> the worst driver peripheral is I2C in fact ;)
2014-11-03T22:44:15 < bvernoux> a real mess in HW and in driver
2014-11-03T22:44:50 < bvernoux> NXP is really better on that ... anyway I ended by rewriting a bit banging I2C driver
2014-11-03T22:44:52 < Tectu_> bvernoux, didn't they fix it after F1'
2014-11-03T22:45:19 < bvernoux> Tectu_: I don't know but I have lost 1 day on that mess ...
2014-11-03T22:46:12 < bvernoux> I imagine it is the same registers as on F1 a very bad heritage ...
2014-11-03T22:46:41 < Tectu_> too bad that barthess isn't around. He has all the possible I2C insights that one might have of the STM32 family
2014-11-03T22:47:04 < bvernoux> the most ugly is all those timeout to wait or polling to do ;)
2014-11-03T22:47:18 < bvernoux> a bit banging driver is 100% better in any case
2014-11-03T22:47:28 < Tectu_> stop saying stupid things
2014-11-03T22:47:54 < Tectu_> if a bit banging driver would be better in 100% of the cases, nobody would bother implementing i2c peripherals into EVERY fucking MCU
2014-11-03T22:47:55 < bvernoux> please be polite I see you have never read the register ...
2014-11-03T22:48:13 < Tectu_> totally wrong there

2014-11-03T23:04:28 < Tectu_> lol :D
2014-11-03T23:04:37 < Tectu_> how well does that work out? Compiler support etc?
2014-11-03T23:04:48 < Tectu_> no stm32 libraries, I assume?
2014-11-03T23:05:00 < Tectu_> or can you use C libraries in ada? (never read a single line of Ada, sorry)
2014-11-03T23:05:10 < Taxman> me too
2014-11-03T23:05:46 < Jamshoot> Yeah, there is no libs at all
2014-11-03T23:06:39 < Jamshoot> compiler support supports few micros from 2012
2014-11-03T23:07:09 < Jamshoot> but nobody care about make libs for stm32
2014-11-03T23:07:16 < Jamshoot> or i dont find it
2014-11-03T23:07:28 < Jamshoot> So i do it for me ^_^
2014-11-03T23:07:47 < tkoskine> You can use C libraries from Ada.
2014-11-03T23:08:08 < Jamshoot> yup
2014-11-03T23:08:36 < Jamshoot> but i dont want
2014-11-03T23:08:50 < Taxman> do you use the gcc ada compiler?
2014-11-03T23:08:58 < Tectu_> What's the motivation to use Ada (on an STM32)?
2014-11-03T23:09:02 < tkoskine> It is pretty easy to add peripheral support from scratch for stm32.

2014-11-04T21:44:04 < PaulFertser> BTW, talking about stencils, this guy says he's using "silhouette portrait" and it works just fine for the purpose.
2014-11-04T21:44:39 < PaulFertser> You'll also probably like his home-made boards with solder mask and silk layers: http://ncrmnt.org/
2014-11-04T21:52:42 < karlp> he's a neat guy :)
2014-11-04T21:53:50 < karlp> I sometimes think he goes about things the hardway, but he's clever, no doubt about that
2014-11-04T21:54:29 < PaulFertser> Also, http://ncrmnt.org/wp/2014/01/13/usb-pcb-toner-transfer-machine-with-web-interface/
2014-11-04T21:54:47 < PaulFertser> Do you also know him? I didn't think he is that famous :)
2014-11-04T21:56:38 < karlp> he wrote some rather odd patches for doign "console" via stlink
2014-11-04T21:57:01 < PaulFertser> Was that him? I remember discussing that topic before.
2014-11-04T21:57:10 < PaulFertser> Right, now I remember.
2014-11-04T21:57:29 < karlp> theres somethign else I saw him doin gthat I thought was really neat, but not at all how I would have done it, don't remember now
2014-11-04T21:57:58 < karlp> oh yeah, parts of this antares stack he's built
2014-11-04T21:58:07 < PaulFertser> He's playing with esp8266 now.
2014-11-04T21:58:10 < karlp> it's got some neat pieces, but an awful lot of single maintainer machinery

2014-11-05T00:40:57 < TheSeven> I suspect that the chip being in sleep mode most of the time confuses openocd
2014-11-05T00:41:30 < TheSeven> while debugging it I'm setting some debug regs to keep clocks running during sleep
2014-11-05T00:41:58 < TheSeven> but if this boots from flash, openocd can't seem to connect
2014-11-05T00:42:14  * TheSeven tries pulling up boot0 to prevent it from executing that sleep mode code

2014-11-05T11:32:22 < Taxman> STM32F42xx and STM32F43xx
2014-11-05T11:32:22 < Taxman> Errata sheet
2014-11-05T11:32:26 < zyp> yeah, I see
2014-11-05T11:32:37 < zyp> how the fuck do they even fuck up that bad
2014-11-05T11:32:48 < Taxman> 2.1.10 PA12 GPIO limitation
2014-11-05T11:33:09 < qyx_> lolz
2014-11-05T11:33:35 < Taxman> so i'll try my luck at mouser now
2014-11-05T11:34:40 < zyp> can't you just disable flash bank 2 though?
2014-11-05T11:34:47 < zyp> or do you need all the flash space?
2014-11-05T11:35:15 < Taxman> no, i do not need it. but as far as i know i can't deactiveta flash bank 2 at the 2MB device
2014-11-05T11:35:34 < Taxman> the dual banking feature can only be disabled at the 1 MB version

2014-11-05T11:36:11 < Taxman> do you know it?
2014-11-05T11:36:22 < zyp> the 1 MB version doesn't even have the second bank, so that's why it's not affected
2014-11-05T11:36:54 < zyp> hmm, no, that's not true
2014-11-05T11:37:03 < Taxman> This limitation is not present in STM32F42xxG and STM32F43xxG part numbers where the
2014-11-05T11:37:03 < Taxman> dual bank feature is disabled

2014-11-05T11:37:47 < zyp> yes, that's what I'm reading as «where the dual bank feature doesn't exist in the first place»
2014-11-05T11:37:51 < Taxman> G is the 1M version, i have I, the 2M version
2014-11-05T11:37:51 < zyp> but I might be interpreting it wrong
2014-11-05T11:37:59 < dongs> < zyp> how the fuck do they even fuck up that bad
2014-11-05T11:38:01 < dongs> LOL
2014-11-05T11:39:46 < zyp> dongs, seriously, how does a gpio signal affect flash reads
2014-11-05T11:39:54 < Taxman> Option bytes (word, address 0x1FFF C008)
2014-11-05T11:39:58 < dongs> yeah thats pretty awful
2014-11-05T11:40:11 < Taxman> DB1M: Dual bank 1 Mbyte Flash memory devices
2014-11-05T11:40:24 < Taxman> i think this is the bit you mean?
2014-11-05T11:40:33 < zyp> yeah
2014-11-05T11:40:51 < Taxman> so i think i have no chance with my 2M device
2014-11-05T11:41:15 < zyp> probably not
2014-11-05T11:41:25 < Taxman> :(
2014-11-05T11:41:32 < zyp> they would probably have mentioned not using the entire flash in the errata sheet if that was a possible workaround
2014-11-05T11:41:40 < Taxman> digikey sent me two times the fast revision
2014-11-05T11:41:53 < Taxman> zyp: I think so too
2014-11-05T11:42:19 < zyp> how big is your code? how about loading it into sram and executing it from there instead
2014-11-05T11:42:20 < Taxman> well i will visit the digikey booth at the electonica in munich and tell them how bad they are ;)
2014-11-05T11:42:26 < qyx_> sometimes i wonder if the manufacturers even test their things
2014-11-05T11:42:43 < zyp> just have a small loader part in flash that loads code to sram before enabling PA12
2014-11-05T11:43:10 < qyx_> Taxman: couldn't you just request another rev? or have the parts replaced with 1M versions?
2014-11-05T11:43:48 < Taxman> zyp: a few kilobytes. but i am just starting with the stm32 right now so this would take way too much time, mastering bootcode, spi flash read and so on ;)
2014-11-05T11:43:49 < qyx_> or you have just few of them
2014-11-05T11:44:11 < zyp> Taxman, no, I mean main flash
2014-11-05T11:44:13 < Taxman> qyx_: Digikey has only the 2M version in qfp144
2014-11-05T11:44:41 < Taxman> zyp: you mean copying the code from main flash to sram?
2014-11-05T11:45:00 < zyp> yes
2014-11-05T11:45:28 < zyp> corruption only happens when PA12 is high, so if you just keep it low until you're done loading, that should be fine
2014-11-05T11:45:56 < Taxman> 30 pages of silicon errata is not good
2014-11-05T11:46:25 < zyp> eh, better to have bugs well documented than not
2014-11-05T11:46:42 < zyp> anyway, I'm out
2014-11-05T11:46:43 < zyp> good luck
2014-11-05T11:46:50 < Taxman> thanks for your help
2014-11-05T11:48:45 < Taxman> is this arm code all relative?
2014-11-05T11:49:29 < dongs> only if you build it so
2014-11-05T11:49:38 < dongs> as position-independent
2014-11-05T11:49:57 < Taxman> this are hard challenges for a first arm project, isn't it?
2014-11-05T11:50:10 < dongs> indeed, why the hell did you choose a huge chip like that

2014-11-05T14:44:18 < emeryth> math is hard
2014-11-05T14:44:42 < dongs> it is, but hte problem is no pcb cad accepts those dimensions

2014-11-05T14:48:28 < Taxman> you mean because they did no specify the center coords?
2014-11-05T14:48:36 < dongs> right
2014-11-05T14:48:40 < dongs> or pad dimensions
2014-11-05T14:48:54 < dongs> i mean, yes, its a 10 second trip to calc.exe to get them but why the fuck should I
2014-11-05T14:49:05 < dongs> why litter datsheet with crap dimensions that nobody can use?
2014-11-05T14:49:17 < zyp> do you even need calc for that?

2014-11-05T16:35:43 < dongs> and remap is for some huge package
2014-11-05T16:35:44 < dongs> ffff
2014-11-05T16:35:52 < dongs> how else im gonna trigger timer for this manchester trash
2014-11-05T16:38:19 < dongs> hmm gonna try sync uart too

2014-11-05T17:37:14 < Taxman> does one here have a stm32F4 cpu on the table?
2014-11-05T17:38:15 < madiz> Taxman: what do you want to know that isn't in the datasheet or package marking docs ?
2014-11-05T17:38:27 < zyp> 2014 - year of stm32f4 on the desktop
2014-11-05T17:38:49 < Taxman> madiz: What revision it is
2014-11-05T17:39:10 < Taxman> it is on the right of the circle in the first row
2014-11-05T17:39:12 < qyx_> Z
2014-11-05T17:39:15 < madiz> you'd have to specify a particular F4 for that
2014-11-05T17:39:29 < Taxman> STM32F429
2014-11-05T17:39:34 < qyx_> then NULL
2014-11-05T17:39:50 < zyp> I have a stm32f429discovery at home
2014-11-05T17:39:52 < zyp> but I'm not home
2014-11-05T17:40:20 < dongs> 429disco are all Y
2014-11-05T17:40:34 < Taxman> i have a stm32f3 discovery at home. it is rev y
2014-11-05T17:41:12 < madiz> the errata shit lists A Y 1 and 3
2014-11-05T17:41:21 < Taxman> yeah
2014-11-05T17:41:43 < Taxman> and y seems to be a early revision with lots of severe problems
2014-11-05T17:42:01 < Taxman> digikey sent me two times now rev Y
2014-11-05T17:42:05 < Taxman> i need rev 3
2014-11-05T17:42:09 < madiz> 1 is Jan 2014,  3 is May 2014
2014-11-05T17:42:31 < Taxman> the question is, does anyone own a rev 3 device?
2014-11-05T17:42:41 < dongs> unlikely
2014-11-05T17:42:46 < dongs> 429 is fucking expensive
2014-11-05T17:42:54 < Taxman> http://www.opaya.de/skoepf/stm32.jpg
2014-11-05T17:43:03 < Taxman> what does this datecode mean?
2014-11-05T17:43:06 < madiz> When you're buying from digikey/mouser etc can you specify a revision ?
2014-11-05T17:43:15 < dongs> Taxman: check datasheet
2014-11-05T17:43:27 < dongs> 330 im gonna guess 2013/week 30?
2014-11-05T17:43:30 < Taxman> datasheet tells year+week
2014-11-05T17:43:42 < Taxman> ahh okay
2014-11-05T17:43:59 < Taxman> so shortly after F4 public announcement i think
2014-11-05T17:44:35 < Taxman> dongs: Fucking expensive? i have an offer of a F429 for less than 7euro in 500 quantity
2014-11-05T17:44:50 < dongs> 7 eur is a lot
2014-11-05T17:45:15 < zyp> eh, not that expensive
2014-11-05T17:45:16 < Taxman> for a arm cpu with 180 MHz, TFT RGB interface and sdram engine
2014-11-05T17:45:17 < dongs> lemme recap
2014-11-05T17:45:32 < zyp> except when you don't need it
2014-11-05T17:45:42 < dongs> 1/ this is  your 1st arm project 2/ you *need* sdram and tft 3/ you're already placing an order for 500 of them
2014-11-05T17:45:56 < zyp> heh
2014-11-05T17:46:00 < Taxman> nono
2014-11-05T17:46:02 < zyp> well, that's amusing :)
2014-11-05T17:46:14 < Taxman> but sram is too expensive for >2 MByte
2014-11-05T17:46:26 < zyp> why do you need that much memory?
2014-11-05T17:46:31 < Taxman> i did not order 500 units. just calculated prices
2014-11-05T17:46:45 < dongs> atmel SAMAD5 is probaly a better choice for your application
2014-11-05T17:46:47 < dongs> whatever teh fuck that is
2014-11-05T17:47:02 < Taxman> zyp: The Frame buffer needs alone 1/2 MByte
2014-11-05T17:47:15 < dongs> http://www.atmel.com/products/microcontrollers/arm/sama5.aspx
2014-11-05T17:47:15 < zyp> doesn't SAMAD5 require multiple supply voltages and shit?
2014-11-05T17:47:19 < karlp> or, you know, a tablet?

2014-11-05T17:47:26 < dongs> check
2014-11-05T17:47:45 < dongs> supports ddr sdram, check
2014-11-05T17:47:54 < dongs> ~500mhz shit, check
2014-11-05T17:48:05 < karlp> madiz: what's that?
2014-11-05T17:48:13 < madiz> picture of dongs
2014-11-05T17:48:37 < Taxman> thats BGA324!
2014-11-05T17:48:44 < dongs> ya so?
2014-11-05T17:48:48 < dongs> are you gonna handsolder 429?
2014-11-05T17:48:58 < Taxman> my board has 4 layers with 0.3mm vias
2014-11-05T17:48:58 < dongs> to a home-etched pcb?
2014-11-05T17:49:05 < dongs> sure, that will work perfectly fine
2014-11-05T17:49:10 < Taxman> of corse. you are talking shit hehe
2014-11-05T17:49:13 < dongs> its only 0.8mm pitch
2014-11-05T17:49:15 < karlp> there's a sam5a xplained board too if you want to test it out
2014-11-05T17:49:24 < dongs> ^ and schematics and gerbers for it.
2014-11-05T17:49:30 < dongs> its probly 6L tho because of ddr.
2014-11-05T17:49:35 < Taxman> my board is already finished
2014-11-05T17:49:36 < zyp> doing bga at home isn't that hard
2014-11-05T17:49:45 < Taxman> i know
2014-11-05T17:49:45 < zyp> not that I've done 0.8mm pitch yet
2014-11-05T17:49:48 < karlp> board's finished and yhou're still ordering singles of unknown rev from digikey?!
2014-11-05T17:49:53 < zyp> but it can't be that much harder than 1mm :p
2014-11-05T17:49:53 < Taxman> but i need a cheap pcb board
2014-11-05T17:50:00 < dongs> my last few projs were 0.8 pitch
2014-11-05T17:50:24 < Taxman> with dogbones and 0.3mm vias?
2014-11-05T17:50:50 < dongs> 10/18mil vias and 5/5 trace/sapce
2014-11-05T17:50:51 < dongs> space
2014-11-05T17:51:28 < zyp> Taxman, 0.3mm drill or total diameter of the via pad?
2014-11-05T17:51:40 < dongs> drill i presume
2014-11-05T17:51:45 < dongs> thats the chinatrashfab minimum
2014-11-05T17:51:54 < zyp> because if that's drill, ask your fab to get a better drill :p
2014-11-05T17:51:57 < karlp> what are dogbones?
2014-11-05T17:52:04 < dongs> karlp: how fpga is fanouted
2014-11-05T17:52:26 < dongs> like ()--()
2014-11-05T17:52:30 < dongs> pad -- trace -- via
2014-11-05T17:52:38 < dongs> usually diagonal, looks like a dogbone.
2014-11-05T17:52:49 < karlp> why is that a feature of a fab ?
2014-11-05T17:52:54 < zyp> it's not
2014-11-05T17:52:59 < zyp> nobody said it was
2014-11-05T17:53:09 < karlp> thought that's what taxman meant
2014-11-05T17:53:11 < dongs> its not, but it requires appropriate capability
2014-11-05T17:53:25 < Taxman> zyp: 0.3mm drill
2014-11-05T17:53:48 < zyp> karlp, the point is to get the via ring away from the solder mask aperture for the bga pad, which requires that they can make small enough vias to fit
2014-11-05T17:54:18 < Taxman> zyp: My pcb manufacturers can produce much smaller vias. but for additional fees
2014-11-05T17:54:36 < dongs> thatis generally the case
2014-11-05T17:55:02 < zyp> shame their base spec is useless then
2014-11-05T17:55:13 < dongs> zyp did you see my attempted innovation
2014-11-05T17:55:19 < zyp> when?
2014-11-05T17:55:20 < dongs> < dongs> http://i.imgur.com/DbQebZJ.png to receive http://i.imgur.com/ZRX8liy.png y/n/m
2014-11-05T17:55:20 < jpa-> "useless"
2014-11-05T17:55:25 < zyp> I've been out all day
2014-11-05T17:55:26 < Taxman> zyp: The point is, a too big ring leads to no pass-through of supply planes between via-forest under the bga
2014-11-05T17:55:40 < dongs> well bro
2014-11-05T17:55:46 < dongs> have you actaully LOOKED at that A5 pinout?
2014-11-05T17:55:53 < dongs> i'd suspect all the power balls are near center
2014-11-05T17:56:01 < dongs> and only outer 3 rows or so max are for i/o
2014-11-05T17:56:02 < dongs> and shit
2014-11-05T17:56:15 < dongs> so you're creating solutions for nonexistent problems
2014-11-05T17:56:21 < zyp> Taxman, no, it doesn't
2014-11-05T17:56:22 < dongs> its not like its a fucking fpga wiht ev ery pin being I/O
2014-11-05T17:57:06 < zyp> Taxman, via-pad clearance on top layer becomes a problem before via-plane-via clearance on inner planes
2014-11-05T17:57:13 < jpa-> Taxman: if you can at all route out the vias on signal layers, surely the power traces can also reach there?
2014-11-05T17:57:39 < Taxman> well, the ATSAMA5D31A-CU seems to be 7.70499euro
2014-11-05T17:57:47 < zyp> dongs, what's that innovation for?
2014-11-05T17:58:14 < Taxman> and it has 160 kbytes ROM??
2014-11-05T17:58:24 < dongs> zyp, that manchester encoded shit
2014-11-05T17:58:24 < jpa-> buying processor modules instead of plain chips is a good way to avoid spending time rerouting the same CPU-DDR traces that have been routed a bazillion times already
2014-11-05T17:58:30 < dongs> that i blogged a while ago
2014-11-05T17:58:34 < zyp> dongs, so what's that shit?
2014-11-05T17:58:45 < dongs> gonna try to tap aux on displayport, so i can snoop on shit like powermanagement/brightness
2014-11-05T17:58:56 < zyp> ah
2014-11-05T17:59:25 < zyp> because this is still the slow kind of aux signalling?
2014-11-05T17:59:29 < dongs> yeah
2014-11-05T17:59:30 < dongs> 1mbps
2014-11-05T17:59:35 < zyp> IIRC they also have a faster mode that can tunnel HS USB
2014-11-05T17:59:37 < dongs> jpa sayz i can read it with a timer
2014-11-05T17:59:40 < dongs> thats dp1.2
2014-11-05T17:59:47 < dongs> 720mbit or someshit, nobody actually uses that
2014-11-05T18:00:42 < zyp> anyway, sounds interesting
2014-11-05T18:00:47 < dongs> anyway, im doing some dp related shit so im gonna try sticking that circuit on there and try to debug if I can grab something off of it
2014-11-05T18:00:53 < dongs> it certainly looks doable from scope pics
2014-11-05T18:01:29 < dongs> its differential/lvds-ish shit, so im ac-biasing it, then adding halfvcc dc offset and gonna use a standard lvds receiver (overkill but cheap) to turn it into ttl
2014-11-05T18:01:55 < zyp> yeah, that sounds reasonable enough
2014-11-05T18:02:01 < dongs> could dick with opamp on just one side and shit but figured if this works it sprobly more reliable..
2014-11-05T18:02:47 < zyp> if this was F3 you could just have used one of the internal comparators
2014-11-05T18:03:00 < zyp> those can feed into timers internally
2014-11-05T18:03:31 < dongs> heh nah, same old F1
2014-11-05T18:03:33 < englishman> where do i find docs on f050?
2014-11-05T18:03:38 < zyp> st.com
2014-11-05T18:03:41 < dongs> im not buying a $7 chip
2014-11-05T18:03:44 < dongs> F050 = new?
2014-11-05T18:03:45 < englishman> its not there
2014-11-05T18:04:01 < englishman> f030, f0x1, f0x2, f0x8
2014-11-05T18:04:06 < zyp> isn't F050 just the plain old F0?
2014-11-05T18:04:16 < zyp> or was that 030?
2014-11-05T18:04:27 < zyp> is there even a 050?

2014-11-05T18:10:36 < jpa-> i had a dream last night that i got a fpga project at work
2014-11-05T18:10:50 < jpa-> it was to be developed with the microsoft version of vhdl, called mshdl
2014-11-05T18:11:09 < jpa-> which was somehow based on html and rendered (synthetized) with internet explorer
2014-11-05T18:11:22 < jpa-> client insisted to use as old version of IE as possible, "for stability"
2014-11-05T18:12:13 < Taxman> a nightmare?
2014-11-05T18:12:17 < jpa-> yes

2014-11-06T02:23:35 < BrainDamage> I guess they recycle the same box for all sort of various lengths as different versions of the cable, but I guess that explation is too rational and would ruin your joke, ohwait
2014-11-06T02:25:02 < GargantuaSauce> i actually bought a couple like that

2014-11-06T04:08:44 < dongs> hm
2014-11-06T04:08:56 < dongs> my analolg pro says i should use bigger caps than 0.1uF for the thing
2014-11-06T04:09:13 < GargantuaSauce> framerates on the dickstarter are way higher than that supports
2014-11-06T04:09:35 < dongs> GargantuaSauce: faster framerates with smaller ROI
2014-11-06T04:11:44 < BrainDamage> don't worry, before compression it's only 1 Gbyte/s
2014-11-06T04:12:22 < GargantuaSauce> kickstarter says 5500fps @ 256x256, datasheet says Xres x Yres = 256 x 256 2260 fps
2014-11-06T04:12:28 < GargantuaSauce> they're all marked up by a similar factor
2014-11-06T04:12:46 < dongs> maybe some new version of that series sensor then? or he's trolling
2014-11-06T04:13:02 < GargantuaSauce> it's ringing all my kickstarter alarms
2014-11-06T04:13:03 < GargantuaSauce> well. most of them
2014-11-06T04:13:16 < GargantuaSauce> at least it's not free energy
2014-11-06T04:13:19 < dongs> huhu
2014-11-06T04:13:30 < dongs> my pal paid for 2 so we'll find out next year.
2014-11-06T04:13:42 < dongs> worst case, he's out of 2grand and i wont get a free highspeed camera
2014-11-06T04:14:43 < GargantuaSauce> ya will definitely be interested to see how it turns out
2014-11-06T04:15:10 < dongs> ok so analog pros, http://i.imgur.com/DbQebZJ.png to receive http://i.imgur.com/ZRX8liy.png im being told the AC caps should be > 100nF for 1mhz signal
2014-11-06T04:15:50 < dongs> because the shit acts as a hpf and  it'll just filter out anything slow
2014-11-06T04:16:23 < gxti> 1/(2*pi*f*c)
2014-11-06T04:16:33 < dongs> wolframalphaing
2014-11-06T04:16:56 < dongs> 'AC resistance'
2014-11-06T04:16:59 < dongs> what the hell am i looking at
2014-11-06T04:17:12 < gxti> plug in f (1mhz) and c (100nF)
2014-11-06T04:17:16 < gxti> get impedance
2014-11-06T04:18:13 < dongs> right, i did that. getting ike 1.6ohm. what does that mean
2014-11-06T04:18:16 < BrainDamage> ac resistance is Zc=1/(2*pi*f*c), when Zc=Zr ( Zr is just resistance ) you have the filter's corner frequency, in short that becomes the 1/(2*pi*f*c) gxti said
2014-11-06T04:18:45 < BrainDamage> technically there's a - and a i in the zc, but who cares
2014-11-06T04:19:00 < gxti> it means that your 1mhz fundamental will see that capacitor as a 1.6 ohm resistor. of course for a square wave you have higher frequency harmonic content too, so maybe 10mhz would be a better figure to test.
2014-11-06T04:19:04 < gxti> in which case it's 16 ohms.
2014-11-06T04:19:23 < BrainDamage> you want the filter's frequency a bit smaller than the 1MHz tough
2014-11-06T04:19:31 < gxti> so as long as your signal is strong enough to drive that receiver through 16 ohms then you're good.
2014-11-06T04:23:47 < dongs> hm i duno if it can or not. i'm just taping existing bus
2014-11-06T04:24:11 < dongs> preferably without affecting it

2014-11-06T06:08:18 < jadew> not about ebay being dicks, but about the fact that the auction I won was a scam
2014-11-06T06:14:15 < jadew> this timebase could use a DAC with higher resolution (it's used to tune the OCXO), I can't seem to get better precision than ~0.3 ppb

2014-11-06T06:17:21 < madist> how are you measuring its stability ?
2014-11-06T06:17:29 < jadew> I already closed the unit
2014-11-06T06:17:48 < jadew> I have my wave gen locked on a rubidium standard
2014-11-06T06:17:52 < jadew> and I'm feeding that to the counter
2014-11-06T06:18:23 < jadew> (the counter is able to output a much cleaner wave than the standard - less jitter and harmonics)

2014-11-06T06:29:38 < jadew> R2COM, I can see the frequency changing
2014-11-06T06:29:56 < jadew> R2COM, oven controlled oscillator
2014-11-06T06:30:15 < jadew> the wave gen is locked on a rubidium freq. standard
2014-11-06T06:31:13 < jadew> measure what?
2014-11-06T06:31:30 < jadew> I'm measuring the output of the wave gen
2014-11-06T06:31:34 < jadew> the ocxo is inside the counter
2014-11-06T06:31:44 < madist> oh.
2014-11-06T06:31:50 < madist> I thought you built your own oxco
2014-11-06T06:31:54 < jadew> ah, no
2014-11-06T06:32:21 < jadew> madist, I wanted to do that at some point, but then I just went online and bought a new ocxo
2014-11-06T06:32:25 < madist> :D
2014-11-06T06:32:52 < jadew> the gettho part was that I had to use a protoboard to reroute the pins so it matched the pinout of the original ocxo
2014-11-06T06:33:16 < gxti> lol...
2014-11-06T06:33:28 < jadew> R2COM, why not?
2014-11-06T06:33:29 < madist> I've been thinking of making my own ocxo using a peltier instead of a heater.
2014-11-06T06:33:38 < madist> so I can run the crystal cold instead of hot.
2014-11-06T06:33:50 < jadew> madist, you can just use a bjt
2014-11-06T06:33:51 < gxti> jadew: good job
2014-11-06T06:34:07 < madist> jadew: use a bjt to do what ?
2014-11-06T06:34:14 < jadew> that's how the original OCXO was heated (I repaired it once)
2014-11-06T06:34:22 < madist> ok
2014-11-06T06:34:23 < jadew> madist, to heat up your crystal
2014-11-06T06:34:38 < gxti> madist: crystals have some frequency where tempco is least, that's where you should hold it. ones made for OCXO have that temperature high enough for oven. plain ones would be room temp, so you'd need to be able to bring temp up and down
2014-11-06T06:34:52 < madist> gxti: yup
2014-11-06T06:35:35 < jadew> yeah, there's a sweet spot for crystals, but if you just want something quickly put together, simply heating it up at a certian temp and holding it there will still give you better performance
2014-11-06T06:35:35 < gxti> R2COM: the ocxo is the internal time base of the counter. it's not being 'probed' and ocxos have builtin output buffers anyway.
2014-11-06T06:35:38 < jadew> gxti, thanks
2014-11-06T06:36:31 < jadew> R2COM, sorry, I didn't understood what you meant, yeah, I'm not probing the OCXO
2014-11-06T06:36:53 < jadew> I'm probing a much more stable signal
2014-11-06T06:37:20 < gxti> i need to get a counter...
2014-11-06T06:37:38 < gxti> too lazy to troll ebay
2014-11-06T06:37:50 < jadew> gxti, I trolled ebay for about a year till I scored this one
2014-11-06T06:37:56 < jadew> paid 100 pounds for it
2014-11-06T06:38:22 < jadew> it has all the bumpers and all that, I just took them off because it didn't fit right on the bench
2014-11-06T06:39:02 < gxti> the only thing it's driving is the internal circuitry of the counter.
2014-11-06T06:39:29 < jadew> R2COM, the OCXO is only driving a buffer
2014-11-06T06:39:47 < jadew> from that buffer the rest of the counter is fed
2014-11-06T06:39:52 < gxti> it's not an oscilliscope, there's no high impedance probe at all in that setup
2014-11-06T06:40:10 < gxti> nothing that can be pulled by capacitance
2014-11-06T06:41:24 < gxti> is being driven by a low impedance function generator
2014-11-06T06:41:30 < jadew> R2COM, the input is properly driven, regardless of capacitance
2014-11-06T06:41:30 < gxti> not a tiny crystal

2014-11-06T15:38:54 < dongs> Please, please, please do not open your doors tonight to anyone you do not know. This evening I had an African American male, about 6' tall and slim build in a white extended van come to my door. He was being aggressively persistent to come into my home to give me a free offer. I shut off my lights yelled through the window that I was not interested. He persisted, so I called the police.
2014-11-06T15:39:57 < Steffanx> The end.

2014-11-06T15:50:48 < PaulFertser> And from the article text it seems like they'll be testing flying drones that can also swim but nothing is told about 3d printers.
2014-11-06T15:51:28 < emeryth> yes we can finally bomb underwater terrorists with 3d printed bombs

2014-11-06T22:12:18 < alex20032> Hi people
2014-11-06T22:13:12 < zyp> hi
2014-11-06T22:13:24 < alex20032> I want to get into the arm world
2014-11-06T22:13:32 < alex20032> But i was wondering where to start
2014-11-06T22:13:45 < alex20032> How does stm32 compare to other?
2014-11-06T22:13:55 < alex20032> In term of peripheral complexity
2014-11-06T22:14:00 < zyp> «how» in what sense?
2014-11-06T22:14:17 < zyp> I'd say it's pretty even to the other large vendors
2014-11-06T22:14:43 < alex20032> Because i want arm + simple peripheral, not over complicated peripheral
2014-11-06T22:14:49 < zyp> some advantages, some disadvantages, but mostly same
2014-11-06T22:15:00 < zyp> what do you mean by complicated?
2014-11-06T22:15:41 < alex20032> Either datasheet unclear, or hard to use peripheral(because too much configuration//too much "flexible" perihperal)
2014-11-06T22:15:43 < zyp> I suspect your «complicated» is similar to my «flexible»
2014-11-06T22:15:59 < kakeman> at least there is some suberb tools for generating initial peripheral code for stm32
2014-11-06T22:16:15 < zyp> datasheets tend to be pretty clear on most stuff
2014-11-06T22:16:18 < alex20032> kakeman: may you eleborate?
2014-11-06T22:16:25 < zyp> every vendor will have exceptions to that
2014-11-06T22:17:27 < kakeman> my friend keeps talking about something called "cube" that you have peripherals running in notime
2014-11-06T22:17:59 < alex20032> I found out atmel ATSAMD21G18 peripheral easier (less complicated, better datasheet explanation) than pic24fj64gb004 one
2014-11-06T22:18:27 < alex20032> this is an example of what i mean by simple
2014-11-06T22:18:44 < alex20032> also, http://stm32.izua.ro/wiki/Beginner_FAQ say that F1 is outdated
2014-11-06T22:18:46 < kakeman> check out stm32cubemx
2014-11-06T22:18:56 < alex20032> Does it mean the F1 family is outdated, or is the F1 discovery board?
2014-11-06T22:19:18 < zyp> it's an overstatement
2014-11-06T22:19:41 < zyp> F1 is the oldest family, and the newer families have various improvements
2014-11-06T22:19:54 < zyp> GPIO AF mapping being the most notable one, in my opinion
2014-11-06T22:20:15 < zyp> but otherwise the F1 will work nicely in a lot of applications
2014-11-06T22:20:20 < zyp> since it's rather cheap
2014-11-06T22:21:26 < alex20032> F# : does the more # is a highter number, mean more complicated/flexible peripheral and more pre configuration to the overall system, or just more power from the mcu?
2014-11-06T22:21:41 < zyp> it's not that simple
2014-11-06T22:22:24 < zyp> F4 is performance family, F3 is analog family (extra analog peripherals), F0 is economy oriented
2014-11-06T22:22:40 < zyp> and then you have L series that are low power oriented, with L0 being both low power and cheap
2014-11-06T22:23:24 < tkoskine> alex20032: stm32 is probably one of the most commonly used, so it is very easy to find help / example code / etc for peripheral handling.
2014-11-06T22:26:07 < kakeman> alex20032: take the hard path with me and turn to nxp lpc
2014-11-06T22:26:27 < alex20032> kakeman: hard path?
2014-11-06T22:28:13 < kakeman> ie. there is no channel for lpc
2014-11-06T22:28:39 < alex20032> if i want to get started with stm32, how should i set up my development environment? Where to get header & linker script?

2014-11-06T22:36:21 < Posterdati> hi
2014-11-06T22:36:56 < Posterdati> is it possible to use olimex arm-usb-ocd-h to flash a nrf51822?
2014-11-06T22:37:36 < zyp> can it do swd?
2014-11-06T22:37:57 < zyp> nrf512822 is cortex-m0 which is swd only
2014-11-06T22:38:06 < zyp> so if the adapter can only do jtag, the answer is no
2014-11-06T22:38:09 < Posterdati> 6 pins connector with swdio sdclk and so on
2014-11-06T22:38:21 < zyp> okay, then it'll probably work
2014-11-06T22:38:56 < Posterdati> I did the board by myself copying a nordic sheet
2014-11-06T22:47:39 < PaulFertser> zyp: ftdi adapters can do swd now.
2014-11-06T22:48:04 < PaulFertser> zyp: even without an swd converter, just a single resistor is enough.
2014-11-06T22:48:17 < Taxman> re
2014-11-06T22:48:19 < zyp> ok
2014-11-06T22:49:10 < Taxman> PaulFertser: You seem to be really familiar with this adapter stuff :)
2014-11-06T22:49:28 < PaulFertser> zyp: fyi http://openocd.zylin.com/gitweb?p=openocd.git;a=blob;f=tcl/interface/ftdi/swd-resistor-hack.cfg;h=04f3a73975782174f0e218c3ab528809348b0885;hb=HEAD
2014-11-06T22:50:37 < PaulFertser> Taxman: heh, yes, at least with the common ones.
2014-11-06T22:51:19 < zyp> PaulFertser, shame it's on TDI, considering how it's colocated with TMS in the official spec
2014-11-06T22:51:38 < zyp> but I guess TDI is on a bidirectional-capable pin, while TMS is not, or?
2014-11-06T22:51:59 < zyp> ah, no
2014-11-06T22:52:04 < zyp> I didn't see the TDO part
2014-11-06T22:52:06 < PaulFertser> zyp: nope, nothing in bidirectional in common ftdi adapters, that's the gotcha.
2014-11-06T22:52:07 < zyp> makes sense
2014-11-06T22:52:16 < zyp> yeah, got it now
2014-11-06T22:52:26 < PaulFertser> Works fine with everything we tried it on so far.
2014-11-06T22:52:58 < PaulFertser> Plus proper (buffered) JTAG-SWD adapters are supported in OpenOCD too.
2014-11-06T22:53:55 < PaulFertser> Posterdati: so give it a try, it should work albeit somewhat slow because of unoptimised nrf51 flash driver.
2014-11-06T22:54:35 < Taxman> and in general? is swd slower than jtag?
2014-11-06T22:54:59 < PaulFertser> No
2014-11-06T22:55:24 < Taxman> faster?
2014-11-06T22:56:02 < PaulFertser> It's just that OpenOCD already has a nice fast nrf51 flash driver, but it requires handling SWD WAITs and that requires rerunning the queue, and that's not implemented yet, so the fast driver works only with stlink and cmsis-dap (those handle waits internally).
2014-11-06T22:56:34 < PaulFertser> IIRC Andreas wrote SWD and JTAG are about the same speed-wise.
2014-11-06T23:01:34 < Taxman> thanks
2014-11-06T23:04:58 < alex20032> almost every manufacturer provide a free ide, or free to some extend : CCS (TI, with gcc support), atmel studio, lpcxpresso(NXP), Kinetis Design Studio (freescale)...
2014-11-06T23:05:00 < alex20032> but stm32

2014-11-06T23:05:29 < alex20032> when i want to get started to stm32, its the only thing that slow me down
2014-11-06T23:05:29 < qyx_> why would you need manufacturer specific ide?
2014-11-06T23:05:32 < zyp> doesn't matter, they are shit anyway
2014-11-06T23:05:49 < zyp> grab gcc-arm-embedded and use whatever code editor you prefer
2014-11-06T23:05:49 < alex20032> i dont want to write header by hand, linker script by hand....
2014-11-06T23:06:00 < zyp> you don't need an IDE for that
2014-11-06T23:06:20 < alex20032> but when they provide an IDE, they also provide all the other thing with it
2014-11-06T23:06:46 < Taxman> this arm-none-eabi is armel?
2014-11-06T23:07:03 < alex20032> armel?
2014-11-06T23:07:10 < alex20032> what is armel?
2014-11-06T23:07:40 < synic> alex20032: what chip are you trying to program
2014-11-06T23:07:46 < alex20032> any stm32
2014-11-06T23:07:52 < Taxman> a architecture
2014-11-06T23:08:02 < synic> is there one specifically?
2014-11-06T23:08:05 < alex20032> Got many discovery board, but no tool to get them programmed
2014-11-06T23:08:11 < synic> cus there are a few gcc/makefile starter templates out there
2014-11-06T23:08:19 < synic> but they are family specific
2014-11-06T23:08:45 < Taxman> hehe
2014-11-06T23:09:00 < Taxman> i reused a makefile from a atmega project
2014-11-06T23:09:20 < alex20032> I dont want each time i want to program a chip to search over the web 20 min to find a linker script, then another 15min to get some header, then write a makefile.....
2014-11-06T23:09:20 < Taxman> the include files were the biggest challenge for me
2014-11-06T23:09:53 < Taxman> alex20032: it can take much more than 15 min for header files
2014-11-06T23:10:19 < Taxman> the header files for the STM32F429 i found deep in the source tree of a evaluation board
2014-11-06T23:10:21 < Taxman> finally
2014-11-06T23:10:22 < alex20032> at least, with a vendor's IDE, all those are included
2014-11-06T23:10:49 < ds2> include files?
2014-11-06T23:10:52 < Taxman> yeah there are *some* things that are better at other vendors ;)
2014-11-06T23:10:55 < alex20032> yep, also got that one : 32F429IDISCOVERY
2014-11-06T23:11:00 < ds2> do you also need your source code typed out for you too?
2014-11-06T23:11:10 < Taxman> ds2: cmsis
2014-11-06T23:11:28 < alex20032> no
2014-11-06T23:11:53 < Taxman> ds2: In a java project, i will do so. here are immigrated bulgarians that write for 35euro/h java code
2014-11-06T23:12:02 < alex20032> All i want is to write my code for my mcu, tell to gcc to compile, flash the chip. Dont want to mess with other thing
2014-11-06T23:12:31 < ds2> never been an issue w/gcc for me
2014-11-06T23:12:33 < ds2> *shrug*
2014-11-06T23:12:54 < ds2> there are annoyances
2014-11-06T23:13:12 < alex20032> Taxman: was sure st was giving header on the device page
2014-11-06T23:13:15 < synic> alex20032: do you have a board right now?
2014-11-06T23:13:20 < alex20032> synic: yes
2014-11-06T23:13:23 < synic> which one
2014-11-06T23:13:32 < alex20032> 3 discovery board : A low power one, F3 and F4
2014-11-06T23:13:38 < alex20032> dont remember if it was L0 or L1
2014-11-06T23:14:42 < zyp> L0 discovery is the one with eink
2014-11-06T23:14:49 < zyp> L1 discovery only has a couple of leds
2014-11-06T23:15:11 < synic> alex20032: https://github.com/synic/stm32f3_stdperiph_template  .. I don't claim it's any good, but it definitely works for the stm32f3discovery board

2014-11-07T03:59:01 < karlp> the original f0 disco is the lame arse one with just two leds, one button, and a, "yay, we included a slab or protoboard in the kit"
2014-11-07T04:00:24 < karlp> Posterdati: you can use the disco boards as SWD dongles, not jtag, but that might be all you meant anyway?
2014-11-07T04:00:34 < ds2> isn't there 2 L1 disco's?
2014-11-07T04:00:45 < karlp> hrm, was there an l100 disco perhaps?
2014-11-07T04:00:49 < ds2> one normal one and one they ship with the NFC board
2014-11-07T04:00:59 < karlp> it might have been lamearse like the original f0 disco
2014-11-07T04:01:24 < karlp> yeha, you're right: http://www.st.com/web/catalog/tools/PF259096
2014-11-07T04:01:29 < karlp> zyp was probably thinking of that one.
2014-11-07T04:01:57 < karlp> I meant this one: http://www.st.com/web/en/catalog/tools/PF258515
2014-11-07T04:03:53 < karlp> alex20032: https://github.com/libopencm3/libopencm3-examples might be interesting as well? linker scripts and makefiles for lots of cortex-m parts
2014-11-07T04:04:30 < ds2> it isn't that hard to write your own linker scripts
2014-11-07T04:04:42 < ds2> look up where ram and flash is and put in the numbers
2014-11-07T04:05:08 < ds2> unless you want to do inplace upgrades or play with bootloaders....
2014-11-07T04:05:14 < ds2> or you are using a nRF51 part ;)
2014-11-07T04:05:23 < karlp> it's not hard once you've written 3
2014-11-07T04:05:29 < karlp> it's a fuckign disaster the first time
2014-11-07T04:06:02 < ds2> you start with one
2014-11-07T04:06:06 < karlp> unless you already _know_ the relationship between linker scripts and startup code and project setup and the phase of the moon.
2014-11-07T04:06:10 < ds2> so it has all the names of sections

2014-11-07T04:06:50 < ds2> it helps to have to deal with a seriously broken gcc port for the HC11 :/
2014-11-07T04:07:30 < karlp> heh, when were you doing that?

2014-11-07T04:07:45 < ds2> probally around 94 or 95
2014-11-07T04:07:46 < karlp> hc11 was my first uni micro, fond memories
2014-11-07T04:07:54 < ds2> it was a uni project
2014-11-07T04:07:58 < karlp> :)
2014-11-07T04:08:22 < ds2> got to the last 2wks and gave up on gcc. windup doing a few all nighters to do it in assembly

2014-11-07T04:10:37 < karlp> yeah, I did our third year project in all asm, fitted into 512 bytes, saved the budget of buying the part with 2k or something
2014-11-07T04:10:57 < ds2> you were able to buy the HC11's?
2014-11-07T04:11:20 < ds2> all I was able to do is get parts from university support
2014-11-07T04:11:34 < ds2> is the 512byte one the F part?
2014-11-07T04:11:52 < karlp> sort of, there were a few hc11 boards in th elabs, and RS/farnell sold a few variants, and one of the fourth years from a year or two before me had made an "improved" hc11 dev board
2014-11-07T04:12:08 < karlp> A1 I think? a few other teams used E2 iirc,

2014-11-07T12:16:43 < jpa-> 500 is still pretty low amount.. so just normal distributors like farnell or digikey
2014-11-07T12:17:06 < dekar> there's no stock anywhere
2014-11-07T12:17:27 < dongs> dekar: i can check for you
2014-11-07T12:17:29 < dongs> tomrorw.
2014-11-07T12:17:51 < jpa-> you'll receive chinese 8051's with "STM32" stamped on top
2014-11-07T12:18:23 < dongs> yeah, i only ordered something like 20k F1s and they were all 8051 with 'dongs' stamped on it.
2014-11-07T12:20:09 -!- phantoxe [~destroy@2a02:4780:1:1::1:123c] has joined ##stm32
2014-11-07T12:24:35 < dekar> dongs, so you'll check whether they can stamp STM32F439N on them for me? :/
2014-11-07T12:25:26 < dongs> dekar: yes
2014-11-07T12:25:46 < dongs> except being serious.
2014-11-07T12:26:42 < dekar> well if you know some reputable distributors that'd be awesome
2014-11-07T12:27:01 < Taxman> 8051 was a cool device
2014-11-07T12:27:09 < Taxman> i started with a 80c32
2014-11-07T12:27:44 < Taxman> with external eprom and code written in assembly language hehe
2014-11-07T12:28:05 < dekar> Taxman, thanks, but no thanks
2014-11-07T12:29:33 < Taxman> hehe
2014-11-07T12:30:22 < _Sync_> wtf
2014-11-07T12:30:43 < _Sync_> when I try to read shit over i2c in my main it works but not out of the systick handler?! wat
2014-11-07T12:31:06 < jpa-> with what kind of function?
2014-11-07T12:31:15 < jpa-> generally, blocking stuff in an interrupt handler is not a good idea
2014-11-07T12:31:22 < dongs> dekar: which specific model?
2014-11-07T12:31:24 < jpa-> also many RTOS functions cannot be used inside interrupts
2014-11-07T12:31:40 < dongs> N is package type, so you dont care flash/etc size?
2014-11-07T12:32:16 < dongs> wonder if shit is even buyabl
2014-11-07T12:32:54 < jpa-> it would be funny to design a system with one of those phantom chips that do not really exist
2014-11-07T12:32:55 < dekar> dongs, I am not too picky as of right now, though 1024kB flash and up would be great
2014-11-07T12:33:14 < dekar> I think they all have 256kB RAM
2014-11-07T12:33:16 < _Sync_> yeah I know that it is not the best idea but it should work, shouldn't it jpa-
2014-11-07T12:33:35 < jpa-> _Sync_: how are you trying to do it? custom code or some premade function?
2014-11-07T12:34:09 < dekar> well we're just deciding on the chip, the alternative would be using a bunch of GPIO expanders :(
2014-11-07T12:34:58 < dongs> dekar: yea you cant buy that shit
2014-11-07T12:35:05 < _Sync_> well, the i2c stuff is basically dongs interrupt code
2014-11-07T12:35:07 < dongs> samples at best
2014-11-07T12:35:12 < dongs> its not even full production
2014-11-07T12:35:21 < _Sync_> and the rest if libopenlolm3
2014-11-07T12:35:26 < dekar> dongs, okay, thanks for checking
2014-11-07T12:35:59 < dongs> you nee the TFBGA13x13 thing right?
2014-11-07T12:36:06 < jpa-> _Sync_: well if it does raw hardware access, yes, it probably should work
2014-11-07T12:36:07 < dongs> 176bga is no?
2014-11-07T12:36:46 < _Sync_> I see that the i2c clock is clocking but there is no data coming back, which is confusing me

2014-11-07T12:37:42 < dongs> when in doubt, use software i2c
2014-11-07T12:37:47 < dekar> dongs, the 176 sadly doesn't have enough pins

2014-11-07T12:38:08 < dongs> dekar: stack some arduinos with i2c gpio expander
2014-11-07T12:38:15 < _Sync_> oh
2014-11-07T12:38:16 < _Sync_> yeah
2014-11-07T12:38:22 < _Sync_> that could be the issue
2014-11-07T12:38:27 < _Sync_> I thought about that
2014-11-07T12:38:30 < dongs> dekar: may I suggest atmel sam A5Dx stuff? shitload of pins and you can code on it bare metal.
2014-11-07T12:38:32 < _Sync_> let me look into that
2014-11-07T12:39:03 < dongs> http://www.atmel.com/products/microcontrollers/arm/sama5.aspx
2014-11-07T12:39:20 < dongs> (also cheaper than F429
2014-11-07T12:41:31 < dekar> dongs, price isn't an issue at all, though it's supposed to stay as compatible with the existing stm32 code from the older product generation as possible
2014-11-07T12:42:12 < dongs> what do y ou need 160 gpios for?
2014-11-07T12:42:20 < dongs> thats a lot of arduino shields
2014-11-07T12:42:29 < dekar> interfacing a shitload of optical transceivers
2014-11-07T12:43:11 < dongs> SFP shit??
2014-11-07T12:43:36 < dekar> yeah those and their 100G siblings
2014-11-07T12:43:53 < Taxman> 100G is then qsfp?
2014-11-07T12:43:59 < Taxman> qsfp+
2014-11-07T12:43:59 < dekar> CFP
2014-11-07T12:44:04 < Taxman> ok
2014-11-07T12:44:07 < Taxman> sounds expensive ;)
2014-11-07T12:44:09 < dekar> and also QSFP+
2014-11-07T12:44:24 < Taxman> but the stm32 can do only 100M ethernet?
2014-11-07T12:44:34 < dekar> it's only for low speed communications anyway
2014-11-07T12:44:47 < Taxman> hehe ok
2014-11-07T12:47:28 < mringwal> akaWolf: sorry for the flooding :( (Colloquy on OS X 10.10, with laptop in sleep mode). I'll try to remember to quit the IRC client before going to bed.
2014-11-07T12:47:39 < _Sync_> hm, the i2c interrupts should be set to priority 0
2014-11-07T12:50:49 < dongs> sync, correct
2014-11-07T12:50:57 < dongs> which stm32 is it
2014-11-07T12:51:16 < _Sync_> stm32f103rg
2014-11-07T12:52:04 < _Sync_> I mean I can get around the issue easily by just setting a flag in the systick int and then looking in the main if it is set but eh
2014-11-07T12:57:59 < Taxman> boys ups brought me another revision y right now. but now it is a stm32f429ZGT6
2014-11-07T12:58:11 < Taxman> where i can switch the second flash bank of
2014-11-07T12:58:12 < Taxman> off
2014-11-07T12:58:35 < Taxman> why the hell are there only those early rev y devices all around?

2014-11-07T16:15:25 < jadew> dongs, always wanted something like that, unfortunately it only makes sense if your iron can heat up in the time it takes to pick it up, till you reach the thing you want to solder
2014-11-07T16:17:04 < jadew> some form of idle detection would also work, my FX 888 doesn't have that
2014-11-07T16:17:17 < jadew> I forgot it on once for 9 hours
2014-11-07T16:18:43 < dongs> well, it does
2014-11-07T16:18:51 < dongs> (heats up instantly
2014-11-07T16:19:15 < jadew> nice
2014-11-07T16:20:14 < jadew> I don't have that kind of demands from my soldering station yet
2014-11-07T16:20:42 < jadew> before getting this one, I used to have an iron that took ~2-3 minutes to heat up
2014-11-07T16:20:52 < jadew> I was litteraly turning it up and then leaving the room
2014-11-07T16:21:17 < jadew> you can do a lot of stuff in 3 minutes
2014-11-07T16:25:53 < jadew> could be worse

2014-11-07T16:28:54 < jadew> I keep it plugged in in the same power strip with a bunch of other stuff that I usually turn off
2014-11-07T16:29:18 < jadew> so even if I leave it on by mistake, there's a high chance I'll just turn the whole power strip off

2014-11-08T03:33:32 < dirty_d> ahhh, it works https://www.youtube.com/watch?v=MyRSDh7Xpfc
2014-11-08T03:36:11 < jadew> with the OCXO running for a couple of days now, my counter has now less than 0.03 ppb accuracy \o/
2014-11-08T03:36:38 < jadew> now I can measure the PWM from my arduino with outmost accuracy
2014-11-08T03:37:20 < dirty_d> OCXO?
2014-11-08T03:37:34 < jadew> dirty_d, oven controlled oscillator
2014-11-08T03:38:32 < jadew> R2COM, was just saying that I'm now getting 0.03 ppb accuracy
2014-11-08T03:38:47 < jadew> it's been on for a couple of days
2014-11-08T03:38:53 < jadew> the oscillator is a trimble
2014-11-08T03:39:15 < jadew> and the freq standard has a 0.005 ppb accuracy
2014-11-08T03:39:35 < jadew> so an order of magnitude higher than what I'm able to measure
2014-11-08T03:39:51 < dirty_d> thats crazy
2014-11-08T03:40:33 < jadew> and before you start questioning the freq. standard, I have two, I measured them against each other and they're the same, at least what I can measure
2014-11-08T03:41:13 < jadew> R2COM, nothing, I just replaced the broken OCXO
2014-11-08T03:41:29 < jadew> R2COM, in the frequency counter
2014-11-08T03:42:04 < jadew> it was working (somtimes) but it was drifting more than i was expecting
2014-11-08T03:46:02 < jadew> what do you have now?
2014-11-08T03:46:45 < jadew> why do you want to upgrade? seems good enough

2014-11-08T03:46:54 < jadew> I have a phenom too
2014-11-08T03:48:09 < jadew> sounds expensive
2014-11-08T03:48:44 < jadew> personally, I didn't need an upgrade since 1.2 GHz @ 1 Gb RAM
2014-11-08T03:49:06 < jadew> luckly PCs break, so I end up upgrading like the rest the world
2014-11-08T03:50:21 < jadew> do those even have any support for graphics and things like that?
2014-11-08T03:50:59 < jadew> maybe that's not needed anymore tho
2014-11-08T03:51:15 < jadew> but I was under the impression that the Xeon line is targetted at servers
2014-11-08T03:52:46 < jadew> I'll upgrade when I'll get 16 cores
2014-11-08T03:53:01 < jadew> could help with compiling some bigger projects, but other than that... waste of money
2014-11-08T03:54:53 < jadew> well, I only have g++ and visual c++ in mind
2014-11-08T03:54:59 < jadew> I don't care about the rest
2014-11-08T03:55:04 < jadew> it can
2014-11-08T03:55:22 < jadew> don't know, I don't use it that often
2014-11-08T03:55:32 < jadew> oh, that one does
2014-11-08T03:55:37 < dirty_d> any compiler uses multiple cores
2014-11-08T03:55:50 < jadew> and it does it since a very long time ago
2014-11-08T03:55:53 < dirty_d> sure it does
2014-11-08T03:55:59 < upgrdman> anyone know what the weird "two boxes side by side" looking things are on this schematic? they're right by all of the ground symbols.  https://www.youtube.com/watch?v=zWod6zINWi8&t=6m4s
2014-11-08T03:56:05 < jadew> R2COM, don't know about the express versions
2014-11-08T03:56:15 < upgrdman> well, right by two of the three ground symbols
2014-11-08T03:56:17 < jadew> yep
2014-11-08T03:56:20 < jadew> I'm a pro dev
2014-11-08T03:56:24 < dirty_d> ive never seen a compiler that didnt let you use multiple cores
2014-11-08T03:56:31 < dirty_d> its more the system that determines that not the compiler
2014-11-08T03:56:48 < jadew> R2COM, I'm not freelancing, it's not me paying for it
2014-11-08T03:56:49 < dirty_d> are you talking about programming with multiple cores, or compiling?
2014-11-08T03:57:28 < jadew> dirty_d, yeah, the system will cycle you through each core, but the compiler has to know to start X threads at the same time
2014-11-08T03:57:30 < dirty_d> i dont think that really matters, jsut compile as many files at the same time as you have cores
2014-11-08T03:57:36 < jadew> that way it will use all the cores at once
2014-11-08T03:57:40 < jadew> so the full power of the CPU
2014-11-08T03:58:07 < dirty_d> jadew, oh you mean like optimizing regular non-multithreaded code to use multiple cores automatically?
2014-11-08T03:58:10 < dirty_d> ive never seen taht
2014-11-08T03:58:21 < jadew> dirty_d, no, just the compiling part
2014-11-08T03:58:24 < dirty_d> oh
2014-11-08T03:58:38 < jadew> on huge projects it takes a lot of time to compile one file at a time
2014-11-08T03:58:49 < dirty_d> if you use make, youre all set
2014-11-08T03:59:10 < jadew> R2COM, the i7
2014-11-08T03:59:19 < jadew> ah
2014-11-08T03:59:34 < jadew> for everything just data crunching, I'd get a xeon for sure
2014-11-08T03:59:58 < jadew> but for regular use, I'd go with the i7, I don't know what the xeon doesn't have (being so specialized)
2014-11-08T04:00:30 < jadew> I did notice about a ten fold increase in performance between a server at work and my pc with full resources dedicated to the project I was testing
2014-11-08T04:00:45 < jadew> and the server is older than my PC
2014-11-08T04:02:15 < jadew> don't know
2014-11-08T04:02:34 < jadew> not my cup of tea, I'd just get the cheapest one

2014-11-08T05:10:48 < GargantuaSauce> got mine from gc_supermarket on fleabay
2014-11-08T05:10:53 < GargantuaSauce> good seller
2014-11-08T05:11:11 < jadew> R2COM1, I didn't compile anything on xeons that would give me an idea on how good they are
2014-11-08T05:11:40 < upgrdman> GargantuaSauce: would VCC be the gate drive voltage (for low side, and pumped for high side) or would it need to be 3V if using 3V pwm?
2014-11-08T05:11:47 < jadew> but I did work on lots of projects that would have benefited from more compiling power
2014-11-08T05:12:10 < GargantuaSauce> it's the gate voltage, logic transition is <3V
2014-11-08T05:12:14 < jadew> R2COM1, yeah, only judging by how they behave with my projects
2014-11-08T05:12:31 < jadew> the performance is amazing on the production server vs what I get on my PC
2014-11-08T05:13:27 < upgrdman> GargantuaSauce: k. and they recommend 10-20V for it. is that just for ideal fet switching? i mean, if you've only up 5V, will he IC still work as expected?
2014-11-08T05:14:12 < GargantuaSauce> i suspect you need 10V, haven't tried lower
2014-11-08T05:14:50 < upgrdman> :(
2014-11-08T05:14:52 < BrainDamage> the voltage depends on how much current your mosfet needs tocarry
2014-11-08T05:15:03 < GargantuaSauce> if you're doing low power stuff at 5v you may as well just use a monolithic bjt bridge or something
2014-11-08T05:15:08 < BrainDamage> there'll be a Ids vs Vgs curve in the datasheet, that sets the min Vgs
2014-11-08T05:15:14 < GargantuaSauce> ST makes a couple nice ones
2014-11-08T05:15:25 < BrainDamage> ofc higher is fine, as long as you're below the breadown voltage
2014-11-08T05:15:40 < BrainDamage> also, those drivers can only supply 100-200mA
2014-11-08T05:15:48 < BrainDamage> depends how fast youswithc it can be a bit low
2014-11-08T05:16:14 < upgrdman> well i've been feeding my gates directly from 3V gpio's with decent results. just want a driver to make high-side nmos better, and to keep transients minimized at the mcu
2014-11-08T05:16:31 < BrainDamage> ok, then you should have 0 issues
2014-11-08T05:16:42 < BrainDamage> except if you exceeed the breakdown voltage :p
2014-11-08T05:17:06 < GargantuaSauce> what fets are you using
2014-11-08T05:17:06 < upgrdman> +/-20V Vgs-break
2014-11-08T05:17:33 < upgrdman> GargantuaSauce: i have literally a box of maybe 5 different fets. all nmod, all to220, about half are logic-level
2014-11-08T05:17:42 < upgrdman> maybe 300 fets
2014-11-08T05:18:10 < upgrdman> even the non-logic-level ones are Vgs-threshold of ~4V
2014-11-08T05:18:19 < upgrdman> so a 5-6V supply is planned
2014-11-08T05:19:15 < upgrdman> and really, i don't even have any plans for them right now. just trying to plan my next cart full with mouser, since i always think of new shit AFTER placing an orde.
2014-11-08T05:20:08 < jadew> welcome to the club
2014-11-08T05:20:35 < upgrdman> lolwut:  http://i.imgur.com/XDlmnq7.jpg
2014-11-08T05:21:20 < jadew> the logic is flawless
2014-11-08T05:22:56 < jadew> and if the suggestion is that he can study, try and fail 1000 times and eventually come up with a solution, than that's more of a turn off than anything
2014-11-08T05:23:28 < GargantuaSauce> just read the appnotes

2014-11-08T06:02:17 < upgrdman> anyone know what the weird "two boxes side by side" looking things are on this schematic? they're right by all of the ground symbols.  https://www.youtube.com/watch?v=zWod6zINWi8&t=6m4s
2014-11-08T06:11:45 -!- dymk [~dymk@2605:6400:20:cbb9:22:6d8:bb6f:9ff5] has joined ##stm32
2014-11-08T06:12:22 < GargantuaSauce> that's the universal symbol for "drawing nets in this schematic capture software is a pain in the ass"
2014-11-08T06:12:30 < dymk> Hello! I'm shopping around for microcontrollers to use with my team's micromouse project, and it seems like the STM32 family of chips is a good place to start
2014-11-08T06:12:53 < dymk> Has anyone used them in micromouse/robotics projects of that ilk before here?
2014-11-08T06:13:19 < GargantuaSauce> not only a good place to start but a good place to stay
2014-11-08T06:13:33 < dymk> that's good to hear
2014-11-08T06:14:00 < dymk> So... it seems like there are a lot of options for chips, do you have any particular recommendations for breakout boards to prototype with?
2014-11-08T06:14:29 < dymk> Some research shows that there are a few boards out there that are quite large, but we'd need something smallish to fit on the bot
2014-11-08T06:14:52 < GargantuaSauce> well if you want to miniaturize you'll probably need to make your own board. there are a few small breakouts though
2014-11-08T06:15:06 < dymk> we're planning on fabbing our own board for the final revision
2014-11-08T06:15:24 < dongs> you need matchboxarm
2014-11-08T06:15:41 < dongs> or my clone which is actually available
2014-11-08T06:16:05 < dymk> What's your clone called?
2014-11-08T06:16:14 < dongs> "STM32 Development Board"
2014-11-08T06:16:18 < dongs> its pretty unimaginative.
2014-11-08T06:16:50 < dymk> do you have a direct link? google is being unhelpful
2014-11-08T06:17:06 < dongs> http://i.imgur.com/Jc9v4.jpg + http://abusemark.com/store/index.php?main_page=product_info&cPath=5&products_id=40
2014-11-08T06:17:36 < dongs> however if youre starting with stm32, you should get a stm32*whatever*discovery
2014-11-08T06:17:37 < dymk> wow, not expensive at all
2014-11-08T06:17:39 < dongs> to get debugger etc.
2014-11-08T06:17:47 < dongs> which will also set you back 10-15$
2014-11-08T06:18:11 < dymk> ah right, can the STM32 do debugging over UART or anything?
2014-11-08T06:18:11 < dongs> or get stlink/jlink stuff off ebay
2014-11-08T06:18:21 < dongs> only if youre into tarduino debugging
2014-11-08T06:20:24 < dymk> hm, seems like the fastest route to getting something usable is just fabbing the custom board asap
2014-11-08T06:20:29 < dongs> yes
2014-11-08T06:20:38 < dongs> its not  that complicated and you will get waht you want.
2014-11-08T06:20:50 < dymk> I'll leave that to the EEs on the team
2014-11-08T06:21:16 < dongs> and you can get really trash looking boards from dirtypcbs.com
2014-11-08T06:21:18 < dongs> for < $10 shipped
2014-11-08T06:21:21 < dongs> or something like that
2014-11-08T06:21:41 < dymk> oh wow
2014-11-08T06:21:47 < GargantuaSauce> it's like $14 for 10 5x5cm
2014-11-08T06:22:12 < dongs> ah, did it went up?
2014-11-08T06:22:13 < dymk> 5x5 is a little small, probably gonna have to do the 10x10
2014-11-08T06:22:30 < GargantuaSauce> and yeah i'd say just get an f0discovery and start rolling your own boards, if you guys know what you're doing already
2014-11-08T06:22:42 < dongs> why f0
2014-11-08T06:22:46 < dongs> is that stlink v2?
2014-11-08T06:22:48 < GargantuaSauce> yes
2014-11-08T06:23:06 < dymk> stlink is the programmer for the chips?
2014-11-08T06:23:11 < GargantuaSauce> programmer and debugger
2014-11-08T06:23:29 < dymk> seems to be windows only
2014-11-08T06:23:32 < GargantuaSauce> nope
2014-11-08T06:23:39 < dongs> how is THAT a problem
2014-11-08T06:23:46 < dongs> real development tools require a real OS
2014-11-08T06:23:46 < GargantuaSauce> openocd supports it
2014-11-08T06:24:02 < dymk> under system requirements: http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/CD00262073.pdf
2014-11-08T06:24:11 < GargantuaSauce> their software requires windows
2014-11-08T06:24:21 < GargantuaSauce> that is not the the only solution
2014-11-08T06:25:20 < dymk> hm, alright. sorry, i'm very new to the environment
2014-11-08T06:25:55 < dongs> if you want a truly lunix only solution you shoul stick with arduino uno
2014-11-08T06:26:32 < GargantuaSauce> actually the arduino software works really badly under linux!
2014-11-08T06:27:01 < GargantuaSauce> the java serial library they use likes to shit the bed
2014-11-08T06:27:13 < dongs>  < GargantuaSauce> actually the arduino software works really badly
2014-11-08T06:27:14 < dongs> ftfy
2014-11-08T06:27:15 < GargantuaSauce> not that that is really any different from its behaviour under windows i guess
2014-11-08T06:27:25 < dymk> oh I'm never using the arduino IDE again
2014-11-08T06:27:27 < dongs> is what you mean i think
2014-11-08T06:28:10 < dymk> it's easy enough to set up avr-gcc
2014-11-08T06:28:27 < dymk> still, arduino uno isn't nearly powerful enough
2014-11-08T06:28:42 < GargantuaSauce> wait what does your little micromouse even need to do
2014-11-08T06:28:45 < dymk> gotta have those hardware counters for wheel encoders
2014-11-08T06:28:57 < dymk> go fast, pathfind, map some arbitrary maze
2014-11-08T06:29:02 < dongs> japs always use some obscure trash for micromice
2014-11-08T06:29:10 < dongs> ive seen a few pcbs g o through for those
2014-11-08T06:29:13 < dongs> and they always haev weird shit
2014-11-08T06:29:18 < dongs> probably renesas or other trash nobody uses
2014-11-08T06:29:28 < GargantuaSauce> oh yeah i was thinking of the sumo class ones. competitive robots are weird.
2014-11-08T06:29:40 < dymk> GargantuaSauce, video supplement: https://www.youtube.com/watch?v=HPvke3fknrc
2014-11-08T06:31:04 < dongs> fffffuuuuuuuu
2014-11-08T06:31:50 < dymk> UCLA always wins because they have this guy, but not this year... we're gonna give them a run for their money
2014-11-08T06:31:52 < dymk> maybe
2014-11-08T06:33:52 < GargantuaSauce> sensors are just the encoders and IR proximity triggers?
2014-11-08T06:34:07 < dymk> and gyro
2014-11-08T06:34:15 < dymk> but yeah, those three
2014-11-08T06:34:49 < dongs> why you need encoders? to know position?
2014-11-08T06:34:55 < dongs> what if the wheels slip
2014-11-08T06:35:11 < dymk> don't go accel enough to make wheels slip
2014-11-08T06:35:17 < dongs> huhu
2014-11-08T06:35:31 < dymk> yep, only way to get position is via encoders though, and possibly gyro
2014-11-08T06:35:44 < dymk> afaict that's more for fine tuning high speed turns though
2014-11-08T06:36:00 < dongs> https://www.youtube.com/watch?v=CLwICJKV4dw
2014-11-08T06:36:14 < GargantuaSauce> seems like the gyro would be redundant if you're eliminating traction issues, i guess the two can work together though
2014-11-08T06:36:24 < GargantuaSauce> and its not like more sensors are a bad thing
2014-11-08T06:36:28 < upgrdman> dymk: what os do you prefer?
2014-11-08T06:36:41 < dymk> upgrdman, my daily driver is osx, so something *nixey
2014-11-08T06:36:46 < upgrdman> i use linux
2014-11-08T06:36:53 < upgrdman> here's my notes for f0 in linux
2014-11-08T06:36:54 < dymk> i *can* boot into windows, but it's not preferred
2014-11-08T06:36:58 < dongs> how do you like the apple storee
2014-11-08T06:37:03 < dongs> and steve's walled garden
2014-11-08T06:37:07 < upgrdman> http://www.farrellf.com/projects/hardware/2014-06-14_Complete_STM32F0_Development_Environment/
2014-11-08T06:37:15 < dymk> dongs, well, i might be working for apple this summer, so i'll find out much more pretty soon :P
2014-11-08T06:37:18 < dymk> upgrdman, thank!
2014-11-08T06:37:22 < dongs> terrible.
2014-11-08T06:37:24 < GargantuaSauce> and we do have a couple other osx users in here
2014-11-08T06:37:34 < upgrdman> dymk: *tips hat*
2014-11-08T06:38:17 < dymk> a little research shows that it's certainly possible to do development on osx. i mean, makes sense, just need a cross compiler and the programmer/debugger
2014-11-08T06:38:21 < dymk> the latter being the harder part
2014-11-08T06:39:00 < dymk> GargantuaSauce, yeah, encoders & gyro are a little redundant, but more sensors can't hurt, and encoders might be too low resolution
2014-11-08T06:39:46 < GargantuaSauce> i wonder how well accelerometer integration would work for odometry in that application
2014-11-08T06:39:49 < GargantuaSauce> would be interesting to try
2014-11-08T06:40:53 < dymk> yeah, i'm sure we'll have room on the pcb, we'll probably throw one on there
2014-11-08T06:41:12 < dymk> dunno how good e-compases are, also something to look into
2014-11-08T06:41:13 < GargantuaSauce> well or just use mpu-6050 or similar
2014-11-08T06:41:22 < dongs> its pretty hard to get a gyro without accelerometer tacked on these days
2014-11-08T06:41:30 < dymk> huh
2014-11-08T06:41:38 < dongs> MPU6500 is pretty nice
2014-11-08T06:41:50 < dymk> hmmm noted
2014-11-08T06:41:56  * dymk scribbles furiously 
2014-11-08T06:41:58 < dongs> and if you want accel+compass, LSM303D is pretty good
2014-11-08T06:42:02  * dymk is the software guy, dammit!
2014-11-08T06:42:15 < GargantuaSauce> i feel like the a magnetometer might not work too well with the motor drivers right next to it on the board but probably worth a try too
2014-11-08T06:44:22 < dymk> does the f0 signify anything in particular/
2014-11-08T06:44:35 < upgrdman> cortex m0
2014-11-08T06:45:00 < dymk> so f3 would be m3, etc
2014-11-08T06:45:00 < upgrdman> although fN doesn't always correspond to mN :/
2014-11-08T06:45:04 < dymk> ah
2014-11-08T06:45:09 < upgrdman> f3 is m4 iirc?
2014-11-08T06:45:16 < GargantuaSauce> yeah f1 is m3, f2 f3 f4 are all m4 or m4f
2014-11-08T06:45:18 < upgrdman> f4 is m4
2014-11-08T06:45:25 < upgrdman> m4f, ya
2014-11-08T06:45:28 < dymk> any reason to go with the f0 over the f1 in this case?
2014-11-08T06:45:34 < upgrdman> cheap
2014-11-08T06:45:36 < dymk> more cortexes == faster gigaflops
2014-11-08T06:45:48 < dymk> we have a 500$ budget
2014-11-08T06:45:50 < GargantuaSauce> the f0 is actually newer than the f1 and has better peripheral designs
2014-11-08T06:45:50 < upgrdman> and less gay than the f1 periphs
2014-11-08T06:45:58 < dymk> thank you IEEE stipend
2014-11-08T06:46:10 < dymk> GargantuaSauce, wait, how's that work? older core I thought
2014-11-08T06:46:19 < GargantuaSauce> oh if you want to blow money and have jiggaflops may as well plunk an f4 on there and be done with it
2014-11-08T06:46:29 < dymk> sweeeet
2014-11-08T06:46:47 < dongs> BUT
2014-11-08T06:46:55 < dongs> F1 has advantage of not needing timecube
2014-11-08T06:47:04 < dymk> is that like a flux capacitor?

2014-11-08T06:47:28 < GargantuaSauce> no pretty sure its http://xn--d-bga.su/shitcopter.jpg
2014-11-08T06:47:28  * dymk frantically buys an f4 board
2014-11-08T06:47:55 < GargantuaSauce> oh dear i still havent bothered to get that flying
2014-11-08T06:48:06 < dongs> make sure to hookup something to headphone connector
2014-11-08T06:48:12 < dongs> maybe you can blast some rap while flying
2014-11-08T06:48:56 < GargantuaSauce> give me your music tracker and it can blast chiptunes
2014-11-08T06:49:46 < GargantuaSauce> or maybe i'd just stream whatever over the rf link
2014-11-08T06:49:55 < dongs> god damn shitty fucking chinese download sites
2014-11-08T06:50:03 < dymk> alright, I've gotta head out, but thanks so much for the advice guys!
2014-11-08T06:50:13 < dymk> i'm sure I'll be on this channel more in the future
2014-11-08T06:50:17 < dongs> GargantuaSauce: need to port tracker to L0
2014-11-08T06:50:23 < dongs> the dickbutt thing

2014-11-08T06:51:22 < dongs> i got it to blinkled and SPI without timecube
2014-11-08T06:51:37 < dongs> slow progress because hating the 'cube
2014-11-08T06:51:52 < GargantuaSauce> i am surprised you're choosing timecube over direct register dickery
2014-11-08T06:52:13 < dongs> direct register dickery sounds like such a fucking waste of time
2014-11-08T06:52:20 < dongs> when I could have just used a working library
2014-11-08T06:52:22 < dongs> if ST didnt gay it up
2014-11-08T06:55:37 < dongs> ugh
2014-11-08T06:55:40 < dongs> that workspace

2014-11-08T09:10:18 < dongs> z80 emulator in that SMS thing is written in ASM
2014-11-08T09:15:32 < jpa-> what is wtf about that?
2014-11-08T09:16:10 < jpa-> instruction set emulators is one of the few places where humans can still do better than compilers
2014-11-08T09:16:34 < jpa-> because the semantics are so strict and optimizing register assignment across instructions etc. can give large benefits
2014-11-08T09:16:51 < dongs> ya sure
2014-11-08T09:16:52 < dongs> still
2014-11-08T09:16:59 < dongs> ok its more like impress than wtf

2014-11-08T10:11:04 < englishman> hows the dildo
2014-11-08T10:12:04 < englishman> found a good resource for dymk http://www.instructables.com/id/How-to-choose-a-MicroController/?ALLSTEPS
2014-11-08T10:13:02 < dymk> thanks for the article, englishman
2014-11-08T10:14:01 < englishman> remember to only use DIP, smt is a huge hassle
2014-11-08T10:14:22 < dymk> englishman, probably going to have to use smt devices
2014-11-08T10:14:35 < dymk> we're fabbing our own board though, so life isn't too bad
2014-11-08T10:14:56 < dymk> also going to pick up an f4 discovery board in the meantime, to get used to the tooling
2014-11-08T10:15:09 < englishman> but how will you breadboard it
2014-11-08T10:16:31 < dymk> breadboarding is for chumps
2014-11-08T10:16:44 < dymk> but uh, i'm going to ignore that part and let the hardware guys deal with it
2014-11-08T10:17:19 < englishman> what are you making
2014-11-08T10:17:23 < dymk> micromouse
2014-11-08T10:17:52 < dymk> meaning the cpu itself is kinda useless to me as the software guy unless it's attached to wheels and sensors anyways

2014-11-08T10:18:50 < englishman> do you have to justify your parts and stuff
2014-11-08T10:18:58 < englishman> or they let you spend $x
2014-11-08T10:19:10 < dymk> more the latter than the former
2014-11-08T10:19:26 < dymk> i'd imagine the only group that needs justification is the team itself
2014-11-08T10:19:38 < dongs> englishman: https://www.youtube.com/watch?v=6GSQARcy3mw
2014-11-08T10:19:46 < dymk> as far as i'm aware, we've got ~$500 to spend on the whole project
2014-11-08T10:20:41 < englishman> unless you have some crazy shit i dont see you needing more than an f0 or avr
2014-11-08T10:20:49 < dongs> eh

2014-11-08T10:22:33 < dymk> well... my past experience with avr is, it's not going to be able to service the motor encoders fast enough alone
2014-11-08T10:23:35 < dymk> could probably get away with f0 yeah, but f4 has FPU which will probably be useful for PID calculations
2014-11-08T10:23:45 < dymk> what's the price difference going to be like between the F0 and F4?
2014-11-08T10:24:26 < englishman> depends where you get them
2014-11-08T10:24:51 < dymk> if it's only a few bucks difference then meh, nbd
2014-11-08T10:29:06 < GargantuaSauce> yeah for a one-off the price point isnt the main concern in any case
2014-11-08T10:31:29 < dongs> i kinda wanna add sound to that emu
2014-11-08T10:32:10 < GargantuaSauce> surely you have a board with i2s in lying around
2014-11-08T10:34:09 < dongs> hm theres accelerometer on 429disco?
2014-11-08T10:34:10 < dongs> or is that gyro

2014-11-08T19:36:46 < Jamshoot> About week ago i have speek with 2 guys here, who used ada
2014-11-08T19:37:18 < Jamshoot> can't remember nicknames
2014-11-08T19:37:33 < Steffanx> but not for stm32 i think, but i could be wrong.
2014-11-08T19:40:54 < Tectu_> Steffanx, make jpa- being available
2014-11-08T19:44:53 < Steffanx> Abrakadabra, Hokkus_pokkus .. jpa- herätä !
2014-11-08T19:46:02 < Steffanx> my magic window says jpa- is here, but he ignores you Tectu_
2014-11-08T19:46:33 < jpa-> worked
2014-11-08T19:46:36 < Tectu_> he really shouldn't do that. I have some serious question that needs to be answered
2014-11-08T19:46:37 < Tectu_> hi jpa-
2014-11-08T19:46:58 < jpa-> will you ask your question in finnish?
2014-11-08T19:47:05 < Tectu_> jpa-, I bought that UV paint from ebay that you once suggested. How much do you apply and how do you apply it?
2014-11-08T19:48:34 < jpa-> Tectu_: 1) stir the paint with a stick  2) put 1-2 drops in the middle of the pcb  3) put a piece of sellophane on top  4) press with a glass plate so that it spreads evenly and very thinly (a good thickness is when you can just-and-just see the traces through it)
2014-11-08T19:49:16 < Tectu_> jpa-, just-and-just see traces?
2014-11-08T19:50:00 < jpa-> 5) take off glass plate, put the transparency mask on the sellophane  6) align the mask exactly, this is impossible  7) expose for 5-10 minutes wiht uv lamp  8) take off sellophane, wash with alcohol/isopropanol/turpentine/paint thinner  9) expose 10 minutes more to make sure it is fully hardened
2014-11-08T19:50:26 < jpa-> Tectu_: yes.. the mask is somewhat transparent, so when it is thin enough you can see the traces
2014-11-08T19:50:32 < Tectu_> jpa-, also, do you let the ink dry before you put it into the UV exposure box?
2014-11-08T19:50:40 < jpa-> i don't
2014-11-08T19:50:49 < Tectu_> thank you sir.
2014-11-08T19:50:59 < jpa-> mostly because it is difficult to apply it evenly enough without the sellophane.. and with a sellophane on top it won't dry
2014-11-08T19:51:22 < Tectu_> what is your reason to use the sellophane instead of directly the mask film?
2014-11-08T19:51:40 < Steffanx> witchcraft isn't allowed in ##stm32 jpa-
2014-11-08T19:51:41 < jpa-> it sticks less to sellophane, so when you remove it it will not peel off the mask with the film
2014-11-08T19:52:07 < jpa-> it is possible to do with just the transparency also, just a bit more difficult
2014-11-08T19:52:31 < Tectu_> I see
2014-11-08T19:52:37 < Tectu_> I assume this will take several tries to get it right
2014-11-08T19:52:45 < qyx_> hmm, do you use alcohol/ipa to dissolve uncured paint?
2014-11-08T19:52:52 < qyx_> it didn't work good here
2014-11-08T19:53:01 < Tectu_> jpa-, sellophane... the kitchen stuff or do you use some dedicated material?
2014-11-08T19:53:02 < jpa-> i use IPA mostly
2014-11-08T19:53:26 < jpa-> paint thinner and IPA both work well for me.. 50% denatured ethanol works but not very well
2014-11-08T19:54:13 < jpa-> Tectu_: i don't use sellophane much in the kitchen, but yeah the transparent film that says "clksjfl" when you crumble it
2014-11-08T19:54:50 < qyx_> that sounds finnish
2014-11-08T19:55:02 < Tectu_> jpa-, I wonder if this stuff would work:  http://www.composti.de/images/product_images/original_images/1._silvex_frischhaltefolie_14.06.2013.jpg
2014-11-08T19:55:09 < Tectu_> that's the fancy foil that sticks to itself
2014-11-08T19:55:26 < jpa-> Tectu_: yeah, it can take some tries.. good news is that when it fails, it usually fails on the "did not stick to pcb" side, so you can just wash the board and try again
2014-11-08T19:55:33 < jpa-> Tectu_: no, not that
2014-11-08T19:56:10 < jpa-> Tectu_: you know the envelopes with a "window" so that you can see the address? that material
2014-11-08T19:56:39 < Tectu_> oh
2014-11-08T19:56:49 < Tectu_> where does one get that stuff from (at these times of the day)
2014-11-08T19:56:57 < qyx_> tesco?
2014-11-08T19:57:15 < jpa-> most stores around here sell it in the area where they sell gift wrapping paper etc.
2014-11-08T19:57:32 < qyx_> or flower shops
2014-11-08T19:57:51 < jpa-> yeah, pick up some flowers for your gf and make sure they wrap it in cellophane
2014-11-08T19:58:13 < jpa-> then after you give them to her and she's like "awwww let me kiss you" you grab the cellophane and run to the bathroom
2014-11-08T19:58:59 < qyx_> and continue with 3
2014-11-08T19:59:26 < Tectu_> if I'd show up with flowers at her place right now she'd probably kick my ass to the moon
2014-11-08T19:59:52 < jpa-> she's angry at you? because of the ugfx license?
2014-11-08T20:00:16 < Tectu_> probably - not sure
2014-11-08T20:00:36 < Tectu_> don't you know these situations where your gf/woman is really really mad with you because you did something but she won't tell you what it is?
2014-11-08T20:01:04 < jpa-> no, mine is sane
2014-11-08T20:01:16 < jpa-> when something is wrong she lets me know
2014-11-08T20:01:18 < Tectu_> good for you - I should probably go for a sane one as well.
2014-11-08T20:01:28 < Tectu_> this is getting anyoing
2014-11-08T20:01:39 < Tectu_> and firmware update was refused the last time
2014-11-08T20:01:43 < jpa-> bad thing is that i'm the not-sane one, being depressed randomly with no good reason at all
2014-11-08T20:02:45 < Tectu_> at least you're not in a "let's break up mode" as I assume
2014-11-08T20:03:26 < jpa-> no, definitely not (atleast if you don't consider being suicidal as breakup mode)
2014-11-08T20:03:46 < Tectu_> how the hack can one be upset because your partner did something wrong and you won't tell what it is - and it seems to be reoccuring once every x months
2014-11-08T20:03:47 < Tectu_> wtf man
2014-11-08T20:04:10 < jpa-> http://chibios.sourceforge.net/docs/hal_stm32l1xx_rm/dot_inline_dotgraph_14.png   this is simple compared to the state machine in relationships
2014-11-08T20:04:12 < Tectu_> nah, that's definitely far from breakup-mode
2014-11-08T20:04:27 < Tectu_> lol'd
2014-11-08T20:05:00 < Tectu_> looks like I'm currently caught in suspend mode
2014-11-08T20:05:49 < jpa-> she never tells you any reason? or have you maybe reacted badly in the past to reasons?
2014-11-08T20:06:43 < Tectu_> no, I am a completely non-reactive person. What ever you tell me I keep calm (It's not that I don't register it, tho!)
2014-11-08T20:06:50 < Tectu_> I never ever freaked out or anything in my entire life
2014-11-08T20:07:41 < jpa-> well that's not the only way to react badly
2014-11-08T20:08:00 < jpa-> refusing to admit fault in yourself or downplaying the issue is bad also
2014-11-08T20:08:20 < Tectu_> oh, I'm exactly the opposit

2014-11-08T20:11:24 < jpa-> the best i can say to him is "duh, it was" (not that i would, though)
2014-11-08T20:11:43 < Tectu_> definitely nothing you can do that is correct in that situation
2014-11-08T20:13:05 < jpa-> well yeah, though to him it probably appears like i'm angry at him (which i kind of am), and the best reason i could possibly give for it is that "i don't like to interact with people who act in irrational ways"
2014-11-08T20:14:24 < Tectu_> so does he try to interact with you now more often to "pull you on his side"?
2014-11-08T20:14:46 < jpa-> not really, and there is not much "whose side" issue anyway (fortunately)

2014-11-08T20:20:35 < Tectu_> jpa-, anyway - I know these kinds of situations... everybody wants you to state your opinion and you know that you best don't say anything and then everybody is upset with you :D
2014-11-08T20:20:46 < Tectu_> and most of the times you really don't have an opinion because you don't care
2014-11-08T20:21:19 < Steffanx> You could combine those two and just state your opinion because you dont really care
2014-11-08T20:21:35 < Steffanx> about people being upset
2014-11-08T20:22:22 < Tectu_> dat solution :D

2014-11-08T23:11:31 < Tectu_> jpa-, UV curing paint... is it photo positive or negative? As in: will black spots stay or white spots stay? I assume white spots will stay as UV cures it? (hence UV curable)
2014-11-08T23:12:08 < jpa-> transparent spots will stay, so you'll want black rectangles over the pads

2014-11-08T23:36:30 < Tectu_> jpa-, wrappings of all sorts. I get a monthly issue of some swiss company that produces packing material and their magazines are for example wrapped into it. as I never look into it I just keep one originally wrapped in my shelf as I might need it once and throw the old one away
2014-11-08T23:36:36 < Tectu_> or towel wrappings etc
2014-11-08T23:38:03 < jpa-> yeah, it is pretty common material, being one of the few environmentally friendly plastics
2014-11-08T23:41:54 < Tectu_> so I have my PCB, the mask, the paint, the UV exposure box, the cellophane and a 3mm glas plate
2014-11-08T23:42:19 < Tectu_> sounds like fun that will yiel many many disappointing results can begin
2014-11-08T23:42:58 < jpa-> if you want less disappointment, make a test run on some blank pcb piece first
2014-11-08T23:43:51 < Tectu_> yep, thanks
2014-11-08T23:44:08 < Tectu_> I went for the blue paint, if you care
2014-11-08T23:44:10 < jpa-> ah, and now that i remember: the pcb has to be dry for the paint to stick - copper absorbs some water in its surface, so washing it right before and drying off with just a towel makes it not stick.. better let it sit around in air for a while (or use a hair dryer or isopropanol to dry it)
2014-11-08T23:44:30 < Tectu_> isorpopanol <3
2014-11-08T23:44:53 < Tectu_> what did you use to stear the paint? Are there any not recommendable materials due tue chemical reactions?
2014-11-08T23:45:56 < jpa-> not that i know of, the paint doesn't seem to be reactive
2014-11-08T23:46:14 < jpa-> i have used a steel axis (the kind that comes from disassembled floppy/cd drives)

2014-11-09T00:01:08 < Tectu_> that stak is faced with right side to UV exposure
2014-11-09T00:01:35 < GargantuaSauce> i mean soldermask
2014-11-09T00:01:52 < Tectu_> sorry, can you clearify your question? my brain is currently half way down
2014-11-09T00:01:53 < jpa-> GargantuaSauce: is there any way to remove soldermask after it has cured? acetone?
2014-11-09T00:02:13 < jpa-> Tectu_: are you using regular photoresist or ink transfer or something for etching?

2014-11-09T00:02:50 < GargantuaSauce> i suspect a much stronger developer solution would do it
2014-11-09T00:03:35 < Tectu_> jpa-, I am using traditional photoresist
2014-11-09T00:04:03 < GargantuaSauce> my poorly worded question was whether you're using the paint as an etchant resist or just as a soldermask
2014-11-09T00:04:12 < GargantuaSauce> cause i guess it can do both
2014-11-09T00:04:23 < Tectu_> GargantuaSauce, ah, just as solder mask. sorry.
2014-11-09T00:04:35 < jpa-> for me, the resolution has been way worse than the photoresist
2014-11-09T00:05:07 < jpa-> i can do 0.5mm with photoresist but sometimes get trouble with 2mm pads for soldermask

2014-11-09T00:05:54 < Tectu_> all my traces are usually 0.254mmm with the same for clearance
2014-11-09T00:05:55 < jpa-> hmm yeah, 0.5mm pitch, 0.2mm traces
2014-11-09T00:06:01 < jpa-> thought error
2014-11-09T00:06:23 < Tectu_> hmm, that paint is taff to get of your skin
2014-11-09T00:06:30 < jpa-> and the smd pads are probably more like 1mm
2014-11-09T00:06:38 < jpa-> use isopropanol?
2014-11-09T00:06:52 < jpa-> or oil helps also and is more skin friendly

2014-11-09T00:07:23 < GargantuaSauce> paint wont be a problem if theres no hand for it to stick to
2014-11-09T00:07:32 < Tectu_> jpa-, sorry, my brain is doing a lot of non-related work today. can you repeate the step after 10minutes exposure again?
2014-11-09T00:07:34 < upgrdman> you guys talking about diy etching?
2014-11-09T00:07:38 < Tectu_> GargantuaSauce, LOL
2014-11-09T00:07:47 < Tectu_> upgrdman, more about diy soldermask, but yes
2014-11-09T00:07:52 < upgrdman> i use photolith, get good results. 10/10mil is easy. 6/6 is doable if you're careful
2014-11-09T00:07:55 < upgrdman> oh
2014-11-09T00:08:02 < upgrdman> i also do that :) dry film

2014-11-09T00:08:37 < jpa-> Tectu_: isopropanol, use it to wash off the unexposed parts
2014-11-09T00:08:53 < jpa-> use a toothbrush to help if it won't come off easily
2014-11-09T00:09:10 < Tectu_> upgrdman, that looks good, but I cannot afford mask
2014-11-09T00:09:15 < Tectu_> upgrdman, film I mean
2014-11-09T00:09:19 < upgrdman> can't afford $25?
2014-11-09T00:09:29 < Tectu_> for how many?
2014-11-09T00:09:32 < jpa-> dry film is somewhat easier, yeah, but difference isn't huge by my experience

2014-11-09T00:10:37 < jpa-> Tectu_: maybe exposure time was too long after all
2014-11-09T00:10:43 < Tectu_> oh, now I whiped it with a towel an all paint gone :)
2014-11-09T00:10:50 < Tectu_> though when I removed the cellophane I could see all patterns
2014-11-09T00:10:52 < jpa-> umm...
2014-11-09T00:11:14 < jpa-> is your cellophane like really weak? because it shouldn't tear very easily
2014-11-09T00:11:41 < Tectu_> jpa-, it is realy strong. I just cut an edge earlied and that is where it has it teared in
2014-11-09T00:11:44 < Tectu_> thorn in*
2014-11-09T00:11:54 < jpa-> ah, yeah
2014-11-09T00:12:12 < jpa-> did the paint remove in flakes or like a liquid?
2014-11-09T00:12:26 < Tectu_> just like liquid
2014-11-09T00:12:49 < jpa-> though if you saw patterns, then atleast the top layer was already exposed, just not exposed all the way through
2014-11-09T00:12:55 < Tectu_> maybe the thickness was too low
2014-11-09T00:12:57 < jpa-> probably too thick layers
2014-11-09T00:13:01 < Tectu_> at the edges it was a bit thicker and there it still stays
2014-11-09T00:13:12 < jpa-> hmm, that sounds strange
2014-11-09T00:13:53 < Tectu_> I took a bare copper PCB with no light sensitive coating, isoproyled it, then a drop of the paint, then cellophane, then glas plate and I pressed really hard
2014-11-09T00:14:04 < Tectu_> it resulted in some circle/elliptical shape, the edges were a bit thicker than the rest
2014-11-09T00:14:12 < Tectu_> and the edges I now can't get off
2014-11-09T00:14:21 < Tectu_> so I have a circle/ellipse now with nothing inside
2014-11-09T00:14:24 < GargantuaSauce> wait doesnt glass block uv?
2014-11-09T00:14:27 < GargantuaSauce> think you want acrylic or something
2014-11-09T00:14:44 < GargantuaSauce> or increase the exposure accordingly

2014-11-09T00:15:41 < jpa-> glass blocks like 80-90% of uv
2014-11-09T00:15:51 < Tectu_> GargantuaSauce, the glas plate was just used to put an even preasure to evenly spread the paint
2014-11-09T00:15:53 < jpa-> but the time i gave is adjusted for glass being present
2014-11-09T00:15:55 < Tectu_> it was removed before exposure
2014-11-09T00:15:58 < jpa-> hmm..
2014-11-09T00:15:58 < GargantuaSauce> ah okay
2014-11-09T00:16:12 < qyx_> interesting
2014-11-09T00:16:14 < jpa-> i think i have had the glass for exposure also
2014-11-09T00:16:22 < qyx_> i had to use 1 hour exposure even without glass
2014-11-09T00:16:27 < jpa-> though i've done the final exposure without anything
2014-11-09T00:16:46 < jpa-> qyx_: nail exposure lamp with transparencies?
2014-11-09T00:17:09 < jadew> are you talking about exposure for photo sensitive PCBs or the mask?
2014-11-09T00:17:14 < jpa-> mask
2014-11-09T00:17:17 < jadew> ah
2014-11-09T00:17:28 < jadew> I saw that link, it's impressive
2014-11-09T00:17:30 < qyx_> jpa-: no, "UV" lamp made of 7300K CFL's
2014-11-09T00:17:37 < jpa-> qyx_: ok, makes sense
2014-11-09T00:17:48 < qyx_> jpa-: pcb exposure was like 4-5min, mask was about 1-2hours
2014-11-09T00:17:52 < jpa-> Tectu_ and me are using the ebay nail uv lamps
2014-11-09T00:17:52 < qyx_> depending on color
2014-11-09T00:18:12 < qyx_> the green could be done in 1hout
2014-11-09T00:18:16 < jadew> what nail uv lamps?
2014-11-09T00:18:21 < qyx_> white one wasn't cured even after 2h
2014-11-09T00:18:23 < jpa-> hmm, my ratios have been like 2-3x photoresist
2014-11-09T00:18:31 < qyx_> interesting
2014-11-09T00:18:45 < jpa-> jadew: type "nail uv lamp" to ebay
2014-11-09T00:18:54 < jpa-> you can choose between pink and white
2014-11-09T00:18:56 < jadew> I typed it in google, didn't know that existed
2014-11-09T00:18:59 < jpa-> i bet Tectu_ got the pink one
2014-11-09T00:19:07 < Tectu_> jpa-, I actually have some 250€ german made exposure box with a crystal glas cover
2014-11-09T00:19:10 < Tectu_> and 4x 8W or something
2014-11-09T00:19:15 < jpa-> oh
2014-11-09T00:19:22 < jadew> I made my own exposure box, soldered ~ 100 LEDs
2014-11-09T00:19:43 < kakeman> why xrystal?
2014-11-09T00:19:56 < jpa-> Tectu_: it might give different ratio of uva/uvb/uvc.. but considering you got some of it cured, your exposure time is somewhat correct
2014-11-09T00:20:00 < kakeman> why not normal
2014-11-09T00:21:05 < jpa-> kakeman: because normal blocks uv?
2014-11-09T00:22:05 < kakeman> i thought so
2014-11-09T00:22:14 < Tectu_> jpa-, it's just odd that the thicker layer sticks and the less thicker layers go of easily
2014-11-09T00:23:03 < jpa-> Tectu_: yeah
2014-11-09T00:23:43 < qyx_> i had the same problem
2014-11-09T00:23:54 < Tectu_> qyx_, how did you fix it?
2014-11-09T00:24:08 < qyx_> i used more paint to make it thicker
2014-11-09T00:24:18 < qyx_> i even tried to apply it in some different ways
2014-11-09T00:24:25 < qyx_> with a brush
2014-11-09T00:24:35 < qyx_> i started considering spraying it and then drying
2014-11-09T00:24:57 < qyx_> then i realized that seeed makes pcb's for $1/pc
2014-11-09T00:25:24 < qyx_> it just need better time management to fight 3weeks idle times
2014-11-09T00:26:06 < qyx_> needs
2014-11-09T00:28:41 < Tectu_> in switzerland 3 weeks are 6 weeks
2014-11-09T00:28:50 < Tectu_> definitely too much for a simple prototype

2014-11-09T00:50:43 < upgrdman> anyone know of a easy solution to driving a half-bridge with only 3V? like a driver ic with built in boost or something?
2014-11-09T00:51:05 < GargantuaSauce> do you not have a higher voltage for the motors anyway
2014-11-09T00:51:14 < GargantuaSauce> stick a 78l12 on there
2014-11-09T00:51:22 < upgrdman> GargantuaSauce: it might be >20V which would fry the gates
2014-11-09T00:51:29 < upgrdman> ya i guess i could do that.
2014-11-09T00:51:57 < amstan> upgrdman: npn transistor + pullup to drive the gate of a p channel?
2014-11-09T00:52:02 < upgrdman> but that IRF ic you mentioned, i think it has low-voltage protection. so i think <10V and it might stop
2014-11-09T00:52:47 < upgrdman> amstan: pull up sucks for high currents. and i've done npn + small half-bridge to push-pull an nmos... but so much waster board space for one fet

2014-11-09T00:53:36 < amstan> the pull up won't be the one carrying the current
2014-11-09T00:53:38 < amstan> that's just for the gate
2014-11-09T00:53:43 < upgrdman> yes.
2014-11-09T00:53:51 < upgrdman> gates need current if pwm'ing at >DC

2014-11-09T01:07:46 < GargantuaSauce> how much current are you switching
2014-11-09T01:08:24 < upgrdman> no project in mind just yet. but let's say the load could see somewhere in the 1-30V 1-30A range.

2014-11-09T01:11:50 < GargantuaSauce> and for bigger stuff you definitely want a better driver anyway since gate capacitance will be higher

2014-11-09T01:50:52 < GargantuaSauce> that doesn't mean it isn't gross
2014-11-09T01:51:04 < GargantuaSauce> also it got better with dx10 i guess, i worked with 9
2014-11-09T01:51:37 < GargantuaSauce> there's 12.
2014-11-09T01:52:17 < GargantuaSauce> depends on a bunch of platform stuff
2014-11-09T01:52:25 < GargantuaSauce> the answer is potentially
2014-11-09T01:53:16 < upgrdman> kakeman: no. no stickers or weird shit.
2014-11-09T01:53:37 < GargantuaSauce> oh it's strictly one-way communication
2014-11-09T01:53:49 < GargantuaSauce> it's a pretty halfassed implementation
2014-11-09T01:54:03 < GargantuaSauce> yep
2014-11-09T01:54:34 < GargantuaSauce> i do the serial comms on the main thread so it's limited by that
2014-11-09T01:54:41 < GargantuaSauce> without that it runs at hundreds of fps
2014-11-09T01:55:30 < GargantuaSauce> the answer to "can" is yes, if it were "do" it would be a no
2014-11-09T01:56:11 < GargantuaSauce> not for that setup
2014-11-09T01:56:26 < GargantuaSauce> my future developments will be a lot more ...engineered
2014-11-09T01:57:02 < GargantuaSauce> sure
2014-11-09T01:57:28 < GargantuaSauce> yeah the two have more or less equivalent functionality
2014-11-09T01:58:03 < GargantuaSauce> though interaction with the windowing system is done with a separate library to opengl
2014-11-09T01:58:15 < GargantuaSauce> and it's a bit more integrated in dx i guess
2014-11-09T01:58:17 < GargantuaSauce> because windows
2014-11-09T01:59:37 < GargantuaSauce> well the same concerns can exist there of course
2014-11-09T02:00:15 < GargantuaSauce> the graphics api doesn't give you magic control over the os scheduler

2014-11-09T02:01:58 < GargantuaSauce> what are you looking at building exactly
2014-11-09T02:02:29 < zyp> R2COM, you're writing to a buffer, and you can sync drawing to buffer refresh
2014-11-09T02:02:37 < zyp> but you don't control when buffer refresh happens

2014-11-09T02:05:30 < zyp> no.
2014-11-09T02:05:40 < GargantuaSauce> your screen is refreshing at a fixed rate
2014-11-09T02:06:02 < GargantuaSauce> with care taken you can have your framerate in lockstep with that
2014-11-09T02:06:10 < GargantuaSauce> or drop frames selectively etc
2014-11-09T02:06:37 < zyp> or draw more than actually gets sent to the monitor
2014-11-09T02:07:15 < zyp> you can draw at 300fps, but if your monitor is running at 60fps, four out of five frames will simply be dropped and never sent to the monitor
2014-11-09T02:07:34 < zyp> that's why vsync is a thing
2014-11-09T02:07:42 < GargantuaSauce> that's not entirely true either, depending on the details you might get horizontal tearig
2014-11-09T02:07:55 < zyp> yes, that's another reason for vsync
2014-11-09T02:08:10 < zyp> R2COM, then you'll have to configure your monitor to that rate
2014-11-09T02:08:40 < zyp> or a multiple, of course
2014-11-09T02:09:14 < zyp> what stuff?
2014-11-09T02:09:26 < GargantuaSauce> why
2014-11-09T02:09:31 < zyp> why do you need it?
2014-11-09T02:10:11 < GargantuaSauce> doing what
2014-11-09T02:10:23 < zyp> well, I can't give you any suggestions without knowing your applications
2014-11-09T02:10:30 < GargantuaSauce> for WHAT?
2014-11-09T02:10:47 < Fleck> does it matter - for what?
2014-11-09T02:10:53 < zyp> Fleck, yes
2014-11-09T02:11:20 < zyp> R2COM, the general answer would be «forget about it, it's pointless»
2014-11-09T02:11:33 < GargantuaSauce> basically
2014-11-09T02:12:01 < zyp> R2COM, unless you have a specific application that requires it, it would be completely pointless, at least
2014-11-09T02:12:05 < GargantuaSauce> if you're trying to draw a 45fps video or whatever just use vsync at 60hz and don't swap the buffer for every fourth frame
2014-11-09T02:12:18 < zyp> R2COM, and if you do, please let me know what it is, and I'll give you further suggestions

2014-11-09T02:26:49 < GargantuaSauce> using the gpu? that's what opengl and directx allow
2014-11-09T02:26:59 < GargantuaSauce> the application doesnt actually touch the graphic buffer
2014-11-09T02:28:17 < GargantuaSauce> well that would require a full simulation of the robot also right? turning that command into actual motion and state and whatever
2014-11-09T02:28:26 < GargantuaSauce> that's a lot more than just graphics
2014-11-09T02:29:07 < GargantuaSauce> another approach would be to send commands to the robot and receive telemetry

2014-11-09T02:31:41 < GargantuaSauce> it's kind of a requirement if you want to be able to accurately draw the robot's state, unless you can accurately simulate its entire environment

2014-11-09T02:37:33 < GargantuaSauce> the framerate shouldn't matter
2014-11-09T02:37:55 < GargantuaSauce> if it did, everything would fail as soon as it is changed by factors out of your control
2014-11-09T02:39:02 < GargantuaSauce> the telemetry should probably have timestamps and then ideally the application works to maintain a constant latency
2014-11-09T02:39:36 < GargantuaSauce> it could drop telemetry samples if it gets behind, or interpolate or extrapolate it to make the visuals smoother
2014-11-09T02:40:00 < GargantuaSauce> there are a lot of ways to make it suck less
2014-11-09T02:40:42 < GargantuaSauce> in theory it shouldn't matter at all how exactly you're drawing stuff
2014-11-09T02:41:15 < GargantuaSauce> no because of modular design
2014-11-09T02:42:20 < GargantuaSauce> yeah either using an rtc or perhaps just the system timer
2014-11-09T02:43:24 < GargantuaSauce> sure
2014-11-09T02:44:10 < GargantuaSauce> depends almost entirely on the rate of telemetry updates

2014-11-09T02:46:23 < GargantuaSauce> okay
2014-11-09T02:47:49 < GargantuaSauce> for a little hexapod? no
2014-11-09T02:47:58 < GargantuaSauce> though i'd definitely make it keep a constant latency

2014-11-09T03:17:59 < GargantuaSauce> is the link reliable?
2014-11-09T03:18:09 < GargantuaSauce> is its latency fixed?
2014-11-09T03:18:22 < GargantuaSauce> those two are mutually exclusive
2014-11-09T03:19:26 < GargantuaSauce> yeah 802.11ac if video is involved
2014-11-09T03:19:40 < GargantuaSauce> otherwise it'll be uhf packet radio
2014-11-09T03:20:11 < GargantuaSauce> the new 5ghz one that sucks less than n
2014-11-09T03:20:56 < GargantuaSauce> probably not ones with spi or uart interfaces
2014-11-09T03:21:09 < GargantuaSauce> not for a few years i imagine
2014-11-09T03:21:33 < GargantuaSauce> i dont even know about usb. the ones i have are pcie
2014-11-09T03:22:04 < GargantuaSauce> but yes heavy host involvement at this level
2014-11-09T03:22:22 < qyx_> uh ac
2014-11-09T03:22:38 < qyx_> do you really need such gigabytez?
2014-11-09T03:22:47 < GargantuaSauce> i want to do multiple video streams
2014-11-09T03:23:19 < qyx_> you mean like 100 HD streams?
2014-11-09T03:23:51 < qyx_> no i mean GargantuaSauce
2014-11-09T03:24:34 < GargantuaSauce> i am thinking about 20 mbits worth of video probably
2014-11-09T03:24:48 < qyx_> classic 802.11a/a should suffice
2014-11-09T03:24:56 < GargantuaSauce> in theory that could be crammed over 802.11g but 2.4ghz is always super noisy
2014-11-09T03:24:57 < qyx_> it can be stable up to ~50mbit
2014-11-09T03:25:01 < qyx_> with 40MHz channels
2014-11-09T03:25:18 < GargantuaSauce> yeah cause 40mhz contiguous is always available on that band
2014-11-09T03:25:19 < GargantuaSauce> totally
2014-11-09T03:25:46 < qyx_> on 5G? theres plenty of space
2014-11-09T03:25:50 < qyx_> at least in EU
2014-11-09T03:26:03 < qyx_> around 300MHz or so
2014-11-09T03:26:05 < GargantuaSauce> and what hardware does 802.11a on 5ghz
2014-11-09T03:26:22 < GargantuaSauce> none i've seen
2014-11-09T03:26:24 < qyx_> common adapters
2014-11-09T03:26:35 < qyx_> we use it quite often
2014-11-09T03:27:10 < GargantuaSauce> anyway whatever i already have the hardware mostly sorted out
2014-11-09T03:27:35 < GargantuaSauce> because video?

2014-11-09T03:34:08 < qyx_> ETSI has bands spread over 5.4-5.8GHz
2014-11-09T03:34:24 < qyx_> there is even one continuous from 5.5-5.7 with 1W eirp
2014-11-09T03:34:29 < qyx_> no, ism
2014-11-09T03:34:49 < GargantuaSauce> actually 5ghz is not ism
2014-11-09T03:34:49 < qyx_> probably not
2014-11-09T03:34:54 < GargantuaSauce> 5.8 is but wifi operates under that
2014-11-09T03:35:00 < qyx_> it depends
2014-11-09T03:35:08 < GargantuaSauce> yeah the licensing situation is....complicated

2014-11-09T03:36:15 < qyx_> yep those sdr channels are usually available to be set on many chipsets
2014-11-09T03:36:49 < GargantuaSauce> i kind of want to get some junk phones and try messing with the baseband processors sometime
2014-11-09T03:36:52 < GargantuaSauce> that'd be interesting
2014-11-09T03:36:58 < qyx_> our local telco office doesn't like to see them
2014-11-09T03:37:10 < GargantuaSauce> because they are cheap and flexible

2014-11-09T03:39:07 < GargantuaSauce> because that band is dead dead
2014-11-09T03:39:13 < GargantuaSauce> yes
2014-11-09T03:39:43 < GargantuaSauce> correct
2014-11-09T03:39:56 < GargantuaSauce> and even outside commercial operations, stomping on those bands can get you in serious trouble
2014-11-09T03:40:12 < qyx_> classical problem in EU are meteo radars on 5600MHz
2014-11-09T03:40:21 < qyx_> 802.11a isn't legal in EU as is
2014-11-09T03:40:28 < qyx_> it is called 802.11h here

2014-11-09T03:42:14 < GargantuaSauce> then the result could range from a warning to arrest i guess
2014-11-09T03:42:41 < upgrdman> "fire at will"

2014-11-09T03:53:16 < dongs> etsi more like etsy
2014-11-09T03:53:19 < GargantuaSauce> another option is to get a ham license and operate in those bands
2014-11-09T03:53:36 < GargantuaSauce> you still have to comply with the regulations for unlicensed devices

2014-11-09T03:55:27 < GargantuaSauce> like work in a big faraday cage

2014-11-09T05:04:50 < dongs> haha
2014-11-09T05:05:00 < BrainDamage> the chunk of metal is a mmds downconverter, he desoldered the oscillator and replaced with a tarduino module

2014-11-09T05:05:41 < BrainDamage> he probably forgot or isn't aware there's several waveguide bandpass filters on the device's frontent
2014-11-09T05:05:59 < BrainDamage> so the shift of the LO made it pretty much deaf
2014-11-09T05:06:12 < GargantuaSauce> i feel like the alligator clips are indicative of the latter
2014-11-09T05:06:30 < BrainDamage> and to make sure of that, he wired alligator clips to extend the coax input

2014-11-09T05:54:36 < jadew> R2COM, don't know what kind of license it has, but it can do directx and has C# bindings
2014-11-09T05:54:48 < jadew> are you planning on selling that application?
2014-11-09T05:55:25 < jadew> is anyone buying C# programs?
2014-11-09T05:57:57 < jadew> in that case I guess people will go for it
2014-11-09T05:58:35  * jadew is working some software too, too bad freaking tektronix came up with that shitlyzer + free signal vu (which is awesome)
2014-11-09T05:58:40 < jadew> *on

2014-11-09T05:59:30 < jadew> or something that corporations use to get the job done fast

2014-11-09T06:00:29 < dongs> no
2014-11-09T06:01:10 < jadew> R2COM, it depends a lot on what you're trying to do
2014-11-09T06:01:24 < dongs> i use C
2014-11-09T06:01:48 < jadew> R2COM, yeah, but the overall thing
2014-11-09T06:01:53 < jadew> for example, if you're making hardware
2014-11-09T06:02:20 < jadew> people are going to buy the hardware and care very little about the fact that they have to install 500 Mb of framework before running your 20k executable
2014-11-09T06:02:56 < jadew> but if you're selling software, it looks very unprofessional to say "you know.. this is done in C#, can you please make sure you have to proper runtime version?"
2014-11-09T06:03:02 < jadew> R2COM, it's not
2014-11-09T06:03:09 < jadew> especially in the electronics world
2014-11-09T06:03:18 < jadew> where people are 20 years behind in terms of software
2014-11-09T06:03:20 < jadew> yeah
2014-11-09T06:04:02 < jadew> R2COM, don't know if it comes with XP for example
2014-11-09T06:04:12 < dongs> nobody should be using XP in 2014
2014-11-09T06:04:29 < jadew> and I know for a fact I can't run some .net things on my system
2014-11-09T06:04:32 < jadew> which is W7
2014-11-09T06:04:50 < jadew> R2COM, lots of people are still using it
2014-11-09T06:05:03 < jadew> as sad as it may be
2014-11-09T06:06:27 < jadew> most people online are dumb tolls
2014-11-09T06:06:45 < jadew> I said most, not all
2014-11-09T06:07:06 < jadew> I can tell you this tho: if you don't know what you're doing C# is better/faster
2014-11-09T06:07:15 < jadew> R2COM, yes
2014-11-09T06:07:28 < jadew> don't think so
2014-11-09T06:07:37 < jadew> there's no reason to change
2014-11-09T06:07:47 < jadew> GUI is easy to do right and you only have to do it once
2014-11-09T06:08:17 < jadew> what about that?
2014-11-09T06:08:36 < jadew> I have classes for that too
2014-11-09T06:08:39 < jadew> in c++
2014-11-09T06:08:50 < jadew> mine
2014-11-09T06:09:03 < jadew> yes, but you only do it once
2014-11-09T06:09:12 < jadew> and then you have complete control over them
2014-11-09T06:09:27 < jadew> a big project, like a CAD package won't care about this small things
2014-11-09T06:09:57 < jadew> UI & utility classes are cheap compared to the rest of the thing
2014-11-09T06:10:04 < jadew> yeah
2014-11-09T06:11:07 < jadew> R2COM, IIRC there's one in the MFC framework
2014-11-09T06:11:16 < jadew> never used it tho, but I think it's there
2014-11-09T06:12:06 < jadew> yeah, it's MFC
2014-11-09T06:12:24 < jadew> R2COM, I avoid it
2014-11-09T06:12:30 < jadew> I prefer WTL
2014-11-09T06:13:52 < jadew> I don't know
2014-11-09T06:14:27 < jadew> could be straight win32 API for all I know with their home grown wrappers
2014-11-09T06:15:02 < jadew> yes
2014-11-09T06:15:05 < jadew> and it's opensource
2014-11-09T06:15:16 < jadew> and completely free of licensing restrictions
2014-11-09T06:16:19 < jadew> and it's template based, so it generates very tight code
2014-11-09T06:16:33 < jadew> very nice library
2014-11-09T06:17:36 < jadew> no
2014-11-09T06:17:46 < jadew> I mean the generated code is very compact
2014-11-09T06:18:15 < jadew> as opposed to MFC
2014-11-09T06:19:34 < jadew> yeah
2014-11-09T06:19:53 < jadew> that means you can't go to them and whine that something is not working
2014-11-09T06:19:54 < dongs> WTL is pretty nice
2014-11-09T06:20:08 < jadew> they give it to your for free, you deal with problems on your own
2014-11-09T06:20:15 < dongs> jadew: is your LA frontend written wiht that?

2014-11-09T06:20:34 < jadew> dongs, most of it, then I mixed it with MFC to get those docking windows
2014-11-09T06:20:47 < jadew> I'm working on a docking windows framework now
2014-11-09T06:21:04 < jadew> I want my next application to be full WTL
2014-11-09T06:21:21 < jadew> R2COM, it doesn't have some things
2014-11-09T06:21:29 < dongs> pretty sure there's a dockshit framework for wtl
2014-11-09T06:21:40 < dongs> by viskoe.dk guy or whatever
2014-11-09T06:21:40 < jadew> MFC didn't have docking windows either, not until the feature plus pack or something like that, introduced with VS 2010
2014-11-09T06:21:49 < jadew> dongs, it is, but it sucks
2014-11-09T06:21:52 < jadew> mine is better
2014-11-09T06:21:54 < dongs> http://www.viksoe.dk/code/fancyui.htm this shit
2014-11-09T06:22:13 < jadew> R2COM, docking windows are not part of the API
2014-11-09T06:22:16 < jadew> they're not native
2014-11-09T06:22:26 < dongs> http://www.viksoe.dk/code/xpui.htm or this
2014-11-09T06:22:27 < jadew> and they're rather complex to implement properly
2014-11-09T06:22:34 < jadew> R2COM, yep
2014-11-09T06:22:46 < jadew> dongs, give me a sec
2014-11-09T06:23:13 < jadew> R2COM, it pretty much translates to a straight win32 API interface
2014-11-09T06:23:16 < dongs> less aids
2014-11-09T06:23:44 < dongs> also statically linked wtl exe isnt over 900megs
2014-11-09T06:23:49 < dongs> like a similar static linked mfc one
2014-11-09T06:23:54 < jadew> yeah
2014-11-09T06:24:05 < jadew> dongs: http://dumb.ro/screenshot/Cxukl.png
2014-11-09T06:24:21 < dongs> ya
2014-11-09T06:24:31 < jadew> that's my version of docking windows with WTL
2014-11-09T06:24:43 < dongs> hes got a few docking classes there, there might bne some that arent completely aids
2014-11-09T06:24:46 < jadew> that was the first test tho, I'm rewriting it from scratch now
2014-11-09T06:25:18 < jadew> dongs, I tried them when I wrote that thing and they're either super slow or they don't behave as expected
2014-11-09T06:26:17 < jadew> the ones I made work just like the VS ones
2014-11-09T06:27:20 < jadew> R2COM, the VS ones are not from MFC, they're made by the VS developers specifically for VS
2014-11-09T06:27:31 < jadew> but yeah, I copied the behvior
2014-11-09T06:27:40 < jadew> *behavior
2014-11-09T06:28:07 < jadew> Visual Studio
2014-11-09T06:29:28 < jadew> probably the best piece of software ever produced by microsoft
2014-11-09T06:31:18 < jadew> R2COM, VS is not made in MFC
2014-11-09T06:31:48 < jadew> I'm talking about the program itself
2014-11-09T06:32:20 < jadew> clearly not straight API and I don't know about the latest versions
2014-11-09T06:33:17 < jadew> at least the previous versions were written with a custom framework
2014-11-09T06:34:03 < jadew> which also allowed MS to sell the program to other companies (like altium) so they could build on their interface
2014-11-09T06:34:16 < jadew> :(
2014-11-09T06:34:20 < jadew> ok...
2014-11-09T06:34:26 < jadew> Visual Studio, the program
2014-11-09T06:34:33 < jadew> is built by microsoft
2014-11-09T06:34:39 < jadew> probably written in C++
2014-11-09T06:34:52 < jadew> they always had a custom framework for it
2014-11-09T06:34:58 < jadew> (in C++)
2014-11-09T06:35:05 < jadew> which they used to build the program (visual studio)
2014-11-09T06:35:35 < jadew> the program itself is extendible and can become any number of tools (like Altium Designer)
2014-11-09T06:35:54 < jadew> now, MFC is a framework provided WITH Visual Studio
2014-11-09T06:36:03 < jadew> that builds upon the win32 API
2014-11-09T06:36:21 < jadew> MFC provides docking windows functionality so you can use it
2014-11-09T06:36:39 < jadew> but they're not the same docking windows that microsoft used for Visual Studio
2014-11-09T06:36:52 < jadew> they're some docking windows they bought from some company called BGF Soft or something like that
2014-11-09T06:37:10 < jadew> because they couldn't be arsed to write a docking windows library for MFC
2014-11-09T06:37:27 < jadew> so you have the docking windows that visual studio is using (the IDE)
2014-11-09T06:37:41 < jadew> and the docking windows that are available to you, to use in your code, the ones from MFC
2014-11-09T06:37:58 < jadew> the MFC ones are buggy and weird
2014-11-09T06:38:07 < jadew> the VS ones are plain awesome
2014-11-09T06:38:33 < jadew> what I did, was to write my own docking windows framework, on top of WTL and copied the behavior from the VS ones
2014-11-09T06:38:46 < jadew> still confused?
2014-11-09T06:39:41 < jadew> cool :)
2014-11-09T06:40:09 < jadew> yes, they're not done yet tho
2014-11-09T06:40:13 < jadew> yeah
2014-11-09T06:40:20 < jadew> you'll probably have more in C#
2014-11-09T06:40:35 < jadew> but again, it depends on what you're doing
2014-11-09T06:40:44 < jadew> heh
2014-11-09T06:41:39 < jadew> I forgot to mention, VS started to go downhil since VS 2008 (including)
2014-11-09T06:42:04 < jadew> it started to suck
2014-11-09T06:42:09 < jadew> missing features
2014-11-09T06:42:17 < jadew> crappy design
2014-11-09T06:42:40 < jadew> my fav. is 2005
2014-11-09T06:42:54 < jadew> 2005
2014-11-09T06:43:00 < jadew> for this project
2014-11-09T06:43:38 < jadew> I can compile the code anytime on VS 2012
2014-11-09T06:44:01 < jadew> I'm only going to move it to 2012 when I'll feel the need to use some features from C++11
2014-11-09T06:44:21 < jadew> at the moment, even tho annoying, I can still live with out them
2014-11-09T06:45:10 < jadew> when I opened VS 2012 for the first time my reaction was "WTF is this ugly piece of shit?"
2014-11-09T06:45:26 < jadew> then I took a better look around and decided I hate it
2014-11-09T06:46:01 < GargantuaSauce> the ribbon is the worst bit of ui design since ....actually i dont think i have a valid comparison
2014-11-09T06:46:55 < jadew> yeah, I don't like it either

2014-11-09T07:10:01 < jadew> don't know on newer versions, but in the past you weren't getting some features, like the resource editor or things like that

2014-11-09T07:25:46 < upgrdman> msdnaa even
2014-11-09T07:26:34 < dongs> hmm, only 1200 now
2014-11-09T07:28:05 < dongs> ah looks like when I bought it i got vs pro with msdn premium
2014-11-09T07:28:11 < dongs> that was probly hte price difference
2014-11-09T07:28:46 < dongs> looks like they dont have that tier now

2014-11-09T07:29:09 < dongs> team/test/ultimate shit
2014-11-09T07:30:28 < dongs> microsoft site is listing Visual Studio Professional with MSDN for $1200. i have no idea where cdw gets that stuff unless its something else

2014-11-09T07:31:27 < dongs> i dunno, sounds like the same shit microsoft is selling for $1200
2014-11-09T07:31:36 < dongs> express = free
2014-11-09T07:31:40 < dongs> profesional = paid
2014-11-09T07:31:53 < dongs> express = no support, non-optimizing compilers, might not work

2014-11-09T07:32:42 < dongs> actually i think i maybe did once

2014-11-09T07:51:21 < dongs> probly
2014-11-09T07:51:40 < dongs> i bought it for msdn, then later switched to technet, then tehy killed that

2014-11-09T08:06:51 < dongs> ya
2014-11-09T08:06:56 < dongs> its same interface i think
2014-11-09T08:07:04 < dongs> just different login or wahtever.
2014-11-09T08:07:22 < upgrdman> ya. i just download ISOs or ZIPs from their msdnaa site, and get the serials.
2014-11-09T08:07:32 < dongs> but you have to be a filthy student and your school must pay for the privilege

2014-11-09T08:10:03 < upgrdman> iirc ms even donated a stack of surface's

2014-11-09T08:14:34 < dongs> i have actually shorted shit out on top of it and have littel burn marks where it happened
2014-11-09T08:14:52 < upgrdman> what's the big black box on that pcb, in the top-right
2014-11-09T08:15:14 < dongs> its just a side-mounted SMT connector
2014-11-09T08:15:20 < dongs> 2x4 pin
2014-11-09T08:15:31 < upgrdman> for?
2014-11-09T08:15:48 < dongs> fuck knows, look at 429-disco schematic :p
2014-11-09T08:15:49 < dongs> its unlabeled
2014-11-09T08:15:54 < dongs> im guessing stlink, but it s non-standard
2014-11-09T08:15:56 < upgrdman> :)
2014-11-09T08:15:58 < dongs> maybe stlink for the stlink cpu?
2014-11-09T08:16:17 < upgrdman> im tempting to buy some 429's. the f0 is nice but it would be good to toy around with something more featureful

2014-11-09T10:06:58 < madist> to wire a standard character LCD running on 5V to a 3.3V STM32 do you put protection resistors on the D0,D1...D7 lines or wire it up directly ?
2014-11-09T10:08:14 < jpa-> what would you be protecting with the resistors?
2014-11-09T10:08:24 < madist> (i didn't read the datasheet yet but I assume all STM32 I/Os are 5V tolerant ?
2014-11-09T10:08:26 < jpa-> most stm32 pins are 5v tolerant
2014-11-09T10:08:30 < jpa-> not all
2014-11-09T10:08:39 < madist> is there a pattern to which ones are not ?
2014-11-09T10:08:52 < jpa-> the datasheet tells
2014-11-09T10:08:55 < madist> ok :)
2014-11-09T10:09:06 < jpa-> i think dac pins, maybe usb etc. are not 5v-tolerant
2014-11-09T10:09:22 < jpa-> also 5v-tolerancy only applies when Vdd is on
2014-11-09T10:10:42 < madist> so back to the original question. do you put resistors on the 5V tolerant I/Os ?
2014-11-09T10:10:50 < madist> just in case.
2014-11-09T10:14:19 < jpa-> i don't, someone might

2014-11-09T13:51:06 < mervaka> sup
2014-11-09T13:51:49 < mervaka> anyone know of an openocd compatible programmer with ulink pro level performance?
2014-11-09T13:52:09 < mervaka> or a way to get the pro working under openocd
2014-11-09T13:52:38 < mervaka> looking to move away from costly keil compiler :(
2014-11-09T13:54:05 < dongs> i duno if pro can be switched to cmsis-dap mode
2014-11-09T13:54:21 < dongs> http://www.keil.com/support/man/docs/ulink2/ulink2_boot_mode.htm
2014-11-09T13:54:36 < dongs> regular ulink2 can, i duno if you can do same wiht pro
2014-11-09T13:55:03 < dongs> and i hope by now openAIDSocd supports cmsis-dap
2014-11-09T13:55:34 < mervaka> yeah we have a few 2s on dap
2014-11-09T13:56:06 < mervaka> but we have this massive 4mb image that takes forever to flash on anything but a pro
2014-11-09T13:56:10 < dongs> https://bbs.archlinux.org/viewtopic.php?id=188356 lol
2014-11-09T13:56:13 < mervaka> fucking bitmaps
2014-11-09T13:56:29 < dongs> is this for production?
2014-11-09T13:56:36 < dongs> or testing
2014-11-09T13:56:36 < mervaka> development
2014-11-09T13:56:52 < dongs> you cant move bitmaps to a fixed region, then use erase sectors to develop?
2014-11-09T13:57:24 < mervaka> not a bad plan tbh
2014-11-09T13:57:41 < dongs> thats what I would do if I had a lot of unchanging r/o shit
2014-11-09T13:57:41 < mervaka> i might look into that
2014-11-09T13:58:09 < mervaka> currently theyre built as a library
2014-11-09T13:58:36 < mervaka> into a defined section of external flash by the scatter file
2014-11-09T13:59:13 < mervaka> but at the moment, images are changing anyway :(
2014-11-09T13:59:28 < mervaka> cool idea though, that needs to happen
2014-11-09T14:00:16 < mervaka> i still need a 25-50mhz programmer for openocd eventually though anyway lol

2014-11-09T14:30:17 < dongs> so they could afford that monitor

2014-11-09T14:30:52 < dongs> The Image Rotation function offers hardware-based switching between portrait and landscape mode. This eliminates the need for special software and does not compromise graphics performance.
2014-11-09T14:30:57 < dongs> haha
2014-11-09T14:31:02 < dongs> you'd have to try real hard to degrade graphics
2014-11-09T14:31:08 < dongs> while rotating
2014-11-09T14:31:35 < qyx_> actually it can be degraded
2014-11-09T14:31:43 < qyx_> at least subpixel hinting
2014-11-09T14:32:11 < qyx_> if the rotation changes pixel rotation without noticing os to change antialiasing settings

2014-11-09T15:24:33 < kakeman> *though
2014-11-09T15:25:21 < BrainDamage> is the brown thing discoloration or reflection?
2014-11-09T15:25:57 < BrainDamage> did you overcook the solder mask?

2014-11-09T15:46:27 < dongs> dildo parts arent gonna arrive monday
2014-11-09T15:46:48 < dongs> runed
2014-11-09T15:47:03 < dongs> at least pcb + stencil is here.
2014-11-09T15:47:16 < dongs> hm i could make one without BT part for now and dick with other shit.
2014-11-09T15:50:05 < dongs> wait no, thats some later shipped shit

2014-11-09T16:42:19 < dongs> you wish you could be working on dildos instead of that uGFX shit
2014-11-09T16:42:23 < jpa-> Tectu_: nice
2014-11-09T16:42:34 < Steffanx> that brown stuff ist Tectu_ .. Tectu_ is a black man.
2014-11-09T16:42:52 < jpa-> the brown stuff totally looks like tectu :D
2014-11-09T16:44:42 < Steffanx> looks nice though, mr Tectu_
2014-11-09T16:44:45 < Tectu_> jpa-, I'm not able to get an even coating
2014-11-09T16:44:48 < Tectu_> thanks Steffanx
2014-11-09T16:44:55 < Tectu_> quite satisfying for the first try
2014-11-09T16:45:01 < Tectu_> first result*
2014-11-09T16:45:10 < jpa-> Tectu_: yeah, it is pretty difficult to get even coating with the paint
2014-11-09T16:45:19 < jpa-> but most of the time it is not that important
2014-11-09T16:45:35 < Tectu_> impossible to get swiss precision with chinese paint
2014-11-09T16:47:51 < Tectu_> I think I should build a rack with a sliding blade
2014-11-09T16:47:57 < Tectu_> the ones that are used for solder paste too
2014-11-09T16:48:20 < Tectu_> but the machanism to adjust the height for the second coating (as PCB will be thinker after the first one) might be tricky
2014-11-09T16:48:38 < jpa-> you do two coats?
2014-11-09T16:49:46 < Steffanx> swiss only do double sized pcbs
2014-11-09T16:50:03 < jpa-> ah
2014-11-09T16:50:30 < Tectu_> jpa-, bottom and top
2014-11-09T16:50:33 < jpa-> you can do swiss precision height adjustment using copier paper
2014-11-09T16:50:55 < jpa-> just put 3-4 sheets under the pcb on the first side
2014-11-09T16:51:05 < Tectu_> hehe :D
2014-11-09T16:51:35 < Tectu_> jpa-, how quick / how much does the paint dry in room light?
2014-11-09T16:51:44 < Tectu_> I got the felling that it was way harder to spread it after about 5min
2014-11-09T16:51:55 < Tectu_> (Yes, it took me 10 min to get an acceptable even coating)
2014-11-09T16:52:03 < jpa-> it will dry (the solvent evaporates) but it will not harden
2014-11-09T16:52:19 < jpa-> so light is not the important thing but air
2014-11-09T16:52:49 < Tectu_> I see
2014-11-09T16:52:56 < jpa-> some people first coat the pcb and then let it dry off before putting on the mask.. i'm not patient enough to watch paint drying
2014-11-09T16:53:26 < Tectu_> yeah, then I can order from seeed and get it in 6 weeks when customs don't fuck up
2014-11-09T16:53:29 < BrainDamage> you can use cling film wrap as temp air barrier
2014-11-09T16:54:05 < Tectu_> I think cellophane should do the trick too
2014-11-09T16:54:17 < jpa-> i should try paint roller for the application some time
2014-11-09T16:54:29 < jpa-> it worked great on our living room wall, so i figure it should work for pcbs also
2014-11-09T16:54:34 < jpa-> they're almost the same thing anyway

2014-11-09T17:03:37 < Tectu_> jpa-, btw, my mask alignment is/was highly accurate on both sides
2014-11-09T17:04:14 < Tectu_> jpa-, I put the film on the PCB first, tape it on one edge, fold it back, clean the PCB using IPA, apply paint, apply cellophane, fold mask back on

2014-11-10T04:58:40 < jadew> it's retarded

2014-11-10T04:58:48 < jadew> yeah
2014-11-10T04:58:52 < dongs> because opensource + arduino
2014-11-10T04:59:05 < dongs> R2COM: check this out < dongs> http://ctopconsult.com/wp-content/uploads/2014/02/Arduino-MonitorTester.pdf
2014-11-10T05:00:10 < jadew> yeah, it looks like it's from the time when they didn't figure out net labels
2014-11-10T05:01:16 < dongs> right
2014-11-10T05:01:19 < dongs> duno if kikecad supports that
2014-11-10T05:01:23 < dongs> maybe its too advanced for opensores
2014-11-10T05:01:38 < jadew> it does
2014-11-10T05:02:16 < jadew> personally I use global net labels, makes more sense than connecting sheets

2014-11-10T05:03:57 < dongs> is that even IR or just some filter trash
2014-11-10T05:04:14 < amstan> dongs: i upped the gain
2014-11-10T05:04:25 < amstan> it's IR from a lepton

2014-11-10T05:07:17 < amstan> jadew: i pointed it at the rpi driving it earlier
2014-11-10T05:07:32 < amstan> but i won't do it again because once the spi wires get out of wack i have to reboot the rpi

2014-11-10T05:07:43 < amstan> it's a fragile protocol
2014-11-10T05:07:55 < jadew> where did you get the core from?
2014-11-10T05:08:01 < jadew> / how much
2014-11-10T05:08:22 < amstan> took apart a flir
2014-11-10T05:08:30 < jadew> heh
2014-11-10T05:08:48 < dongs> if its more than $1k you can just get E4, hax it to 320x240, and use as webcam
2014-11-10T05:08:53 < jadew> do they have nicer resolution due to post-processing than what you have there?
2014-11-10T05:09:11 < amstan> i don't think so
2014-11-10T05:09:35 < amstan> though... this module could do 27fps, but it's module limited to 9
2014-11-10T05:09:42 < amstan> it just sends you each frame 3 times
2014-11-10T05:10:28 < dongs> tho if you just want a cheap thermal cam, seekthermal seems to be usable

2014-11-10T05:11:00 < amstan> dongs: seek is a lot noisier
2014-11-10T05:11:10 < dongs> amstan: no doubt
2014-11-10T05:11:12 < jadew> R2COM, that thought crossed my mind

2014-11-10T05:12:43 < dongs> R2COM: you can set capabilities
2014-11-10T05:12:52 < dongs> that will force to use hardware
2014-11-10T05:12:55 < jadew> R2COM, don't know, I don't do graphics
2014-11-10T05:13:09 < dongs> if capability is not available, it wont render.
2014-11-10T05:13:15 < dongs> (and give some errro etc)
2014-11-10T05:13:39 < jadew> dongs, I suppose interface libraries can fall back to software rendering, right?
2014-11-10T05:15:25 < dongs> jadew: yeah, of course. thats why you check caps and fail if it will use software for something you want to make sure is on hardware
2014-11-10T05:15:28 < upgrdman> nice chemistry textbook:  http://i.imgur.com/L9dXfvA.jpg
2014-11-10T05:15:40 < dongs> it will *always* fall back if there's no hardware cap for it,
2014-11-10T05:15:53 < dongs> but it might be shit/slow
2014-11-10T05:17:12 < dongs> heh its funny how promo video on seekthermal site is made with a $50k flir
2014-11-10T05:18:08 < jadew> they bought thermal.com

2014-11-10T05:24:42 < jadew> those people are freaking rich
2014-11-10T05:24:50 < brabo> it could be ye

2014-11-10T05:28:28 < jadew> just for the purpose of hating him

2014-11-10T05:29:38 < jadew> I suppose it's a matter of taste
2014-11-10T05:29:47 < dongs> indeed
2014-11-10T05:30:33 < jadew> I think she's super doable

2014-11-10T05:32:27 < jadew> there's something twisted in my mind that can make almost any chick attractive in some way
2014-11-10T05:32:34 < brabo> well
2014-11-10T05:32:40 < dongs> youre not 13 right?
2014-11-10T05:32:45 < jadew> I'm not
2014-11-10T05:32:45 < brabo> almost anyone *is* attractive in some way
2014-11-10T05:33:08 < brabo> just not to everyone
2014-11-10T05:33:23 < jadew> so what's your idea of hot?
2014-11-10T05:33:51 < brabo> french have a nice saying that translated goes a bit like: you can't discuss colors and tastes
2014-11-10T05:33:51 < jadew> until now I thought Jessica Alba would fit anyone's idea of hot, I guess I was wrong
2014-11-10T05:34:23 < jadew> brabo, romanians have an idea that translated sounds like: you can't shit in someone's taste
2014-11-10T05:34:31 < brabo> jadew: haha

2014-11-10T05:39:26 < brabo> :)
2014-11-10T05:39:49 < dongs> if I was offered any hollywood garbage to sleep with, even for free, shit, even if they paid me, i'd refuse.
2014-11-10T05:40:09 < jadew> dongs, any hollywood garbage?
2014-11-10T05:40:09 < brabo> dongs: but.. but.. you do not have to think with it!
2014-11-10T05:40:15 < brabo> in fact.. you better not..
2014-11-10T05:40:17 < dongs> all those chicks are used/damaged goods + 99% are ugly as shit
2014-11-10T05:40:31 < jadew> dongs, ok, now I'm really curious
2014-11-10T05:40:38 < dongs> or maybe 99.999, i can't think of anyone off hand that I've seen and thought "hey that looks cute"
2014-11-10T05:40:42 < jadew> show us a picture of a hot chick
2014-11-10T05:41:08 < dongs> dont have time to look
2014-11-10T05:41:57 < jadew> if I type "hot chick" in google images, I agree with most results there
2014-11-10T05:42:15 < GargantuaSauce> http://i01.i.aliimg.com/wsphoto/v0/487801549/VOCALOID-Hatsune-miku-Dakimakura-Case-217.jpg ^
2014-11-10T05:46:03 < dongs> lulz
2014-11-10T05:46:15 < dongs> jadew: trying, but i am guessing i wil probably puke
2014-11-10T05:46:28 < dongs> uh, no.
2014-11-10T05:46:30 < dongs> closing.
2014-11-10T05:47:09 < jadew> ok, then your idea of a hot chick is deffinitely skewed, because those chicks are seriously bangable
2014-11-10T05:48:23 < jadew> for the record, hot doesn't mean it has to be wife material
2014-11-10T05:48:34 < jadew> *she
2014-11-10T05:48:53 < jadew> see brabo? I corrected myself
2014-11-10T05:49:25 < dongs> nice. dicknplaced 12 boards today, all 12 working, $4k is minee
2014-11-10T05:49:44 < jadew> $4k / 12 boards?
2014-11-10T05:49:48 < dongs> ya
2014-11-10T05:49:50 < jadew> wth did you assemble?
2014-11-10T05:49:56 < brabo> ye jadew
2014-11-10T05:50:20 < brabo> tho i do not find the majority of women with that search term to be hot
2014-11-10T05:50:24 < dongs> expensive dtv testing shit
2014-11-10T05:50:37 < dongs> http://bbs.feng.com/read-htm-tid-8563343.html lols
2014-11-10T05:50:52 < brabo> also, at least half those pics are photoshopped
2014-11-10T05:51:10 < jadew> brabo, like it matters
2014-11-10T05:51:32 < brabo> jadew: sure it matters, they are not showing real women
2014-11-10T05:51:44 < jadew> it's not like you're going on a date with them, so it might as well be perfect
2014-11-10T05:51:48 < dongs> the other half are probably so loose your dick wouldnt stay in
2014-11-10T05:51:59 < brabo> dongs: idd hehe
2014-11-10T05:52:12 < brabo> can't eat alone from a beautiful table :p
2014-11-10T05:52:39 < jadew> brabo, I know another saying for that
2014-11-10T05:53:00 < jadew> "you can either have a cake and eat it with your friends, or a shit and eat it alone"
2014-11-10T05:53:15 < brabo> haha
2014-11-10T05:53:17 < GargantuaSauce> what about having your cake and eating it too
2014-11-10T05:53:18 < brabo> nice one ^^
2014-11-10T05:53:24 < GargantuaSauce> where does that factor in??
2014-11-10T05:54:23 < jadew> GargantuaSauce, I didn't even consider the posibility that the cake wouldn't eat it
2014-11-10T05:56:46 < dongs> R2COM: eh i duno i bought some anus shit because gigabyte didnt have any Z87 stuff except gaymer trash
2014-11-10T05:56:56 < dongs> or was it z97? whgatever
2014-11-10T05:57:17 < dongs> Asus Z97-A
2014-11-10T05:58:08 < dongs> cool
2014-11-10T05:58:17 < dongs> EATX, you might need a new case
2014-11-10T05:59:10 < GargantuaSauce> evga is definitely my favourite mobo manufacturer
2014-11-10T06:00:07 < dongs> PCI-E Slot Arrangement . 1x16, 2x16, 3x8, 4x
2014-11-10T06:00:18 < GargantuaSauce> the sideways sata ports kind of suck but there's limited options for placing 10 of them i guess
2014-11-10T06:00:40 < dongs> yeah i found sideways ports on my Z97 shit prety ghetto too
2014-11-10T06:00:58 < dongs> it leaves like ~2cm between edge of drive tray and the board to plug shit in
2014-11-10T06:01:02 < dongs> had to bend cables and fuck with it
2014-11-10T06:01:10 < dongs> right, its probly ok for more open case
2014-11-10T06:01:41 < GargantuaSauce> the graphical bios interface looks pretty infuriating but they're all like that these days
2014-11-10T06:02:31 < GargantuaSauce> pretty 'spensive but looks good
2014-11-10T06:03:17 < GargantuaSauce> oh yeah didnt notice the socket
2014-11-10T06:03:18 < jadew> the sideways ports make sense for cable management
2014-11-10T06:03:26 < GargantuaSauce> yeah that is sort of the "i insist on blowing all my jewgold on this pc" tier
2014-11-10T06:03:51 < jadew> because you normally take the sata cables through the back of the case
2014-11-10T06:05:25 < GargantuaSauce> it's extreeeem
2014-11-10T06:06:11 < jadew> R2COM, you should approach this like with any electronic design: set goals, make it as cheap as possible
2014-11-10T06:06:18 < GargantuaSauce> looks like it has more pcie lanes
2014-11-10T06:06:39 < GargantuaSauce> and PLX PEX 8747 whatever the shit that is
2014-11-10T06:06:48 < GargantuaSauce> also SAS
2014-11-10T06:07:23 < GargantuaSauce> go for the cheaper one
2014-11-10T06:07:40 < GargantuaSauce> scsi
2014-11-10T06:08:04 < GargantuaSauce> do you want to spend 5x as much on harddrives?
2014-11-10T06:08:42 < GargantuaSauce> yes
2014-11-10T06:08:49 < GargantuaSauce> those will be sata anyway i assume
2014-11-10T06:09:58 < GargantuaSauce> dont think so
2014-11-10T06:14:34 < GargantuaSauce> it's right there in the specs dude
2014-11-10T06:14:54 < GargantuaSauce> i would go for the evga one unless there's something specific you want from the fancier one
2014-11-10T06:15:18 < GargantuaSauce> Software - EVGA E-LEET Tuning Utility
2014-11-10T06:15:20 < GargantuaSauce> you're fuckin set
2014-11-10T06:15:30 < GargantuaSauce> wait can you even get 16gb ddr4 modules
2014-11-10T06:15:39 < upgrdman>  <GargantuaSauce> what about having your cake and eating it too
2014-11-10T06:15:48 < upgrdman> what about having your shit and eating it too?
2014-11-10T06:15:49 < upgrdman> :)
2014-11-10T06:16:01 < GargantuaSauce> man newegg's site sucks
2014-11-10T06:16:15 < upgrdman> ok
2014-11-10T06:16:28 < GargantuaSauce> lol
2014-11-10T06:16:36 < GargantuaSauce> overruled.
2014-11-10T06:17:15 < GargantuaSauce> i can find 8 max
2014-11-10T06:17:35 < GargantuaSauce> which is funny because one of the benefits of ddr4 was supposed to be a doubling of density?
2014-11-10T06:17:40 < GargantuaSauce> and you can get 16gb ddr3 modules
2014-11-10T06:17:45 < GargantuaSauce> i think they just aren't on the market yet
2014-11-10T06:18:15 < GargantuaSauce> because it's stupidly expensive
2014-11-10T06:18:35 < upgrdman> R2COM: just buy a mac book pro and a sweet laptop bag. /s
2014-11-10T06:18:49 < GargantuaSauce> >2x the price of ddr3
2014-11-10T06:18:52 < GargantuaSauce> not commodity yet
2014-11-10T06:19:46 < GargantuaSauce> also when i said 16gb ddr3 modules i meant 8
2014-11-10T06:20:41 < upgrdman> mmmm time for some code refactoring. one of my java .class's is 600 lines
2014-11-10T06:21:26 < GargantuaSauce> well buy like 8 or something for now
2014-11-10T06:21:30 < upgrdman> why so much RAM? for allegro or whatever it's called?
2014-11-10T06:21:31 < GargantuaSauce> and get 16gb modules when they hit the market
2014-11-10T06:21:56 < upgrdman> emag?
2014-11-10T06:22:06 < upgrdman> oh. nice.
2014-11-10T06:22:09 < GargantuaSauce> why are you not doing that shit on the gpu
2014-11-10T06:22:22 < dongs> http://www.officedepot.com/a/products/459419/HP-Stream-7-5701-Windows-Tablet/?cm_mmc=PLA-_-Google-_-Computers_Tablets-_-459419-VQ6-41150333996-VQ16c-VQ17-pla-VQ18-online-VQ19-459419-VQ20-75212253956-VQ21-
2014-11-10T06:22:26 < dongs> nice
2014-11-10T06:23:55 < GargantuaSauce> well you ARE looking at getting ddr4 based hardware long before it's commodity
2014-11-10T06:24:13 < GargantuaSauce> you always waste a shitton of money that way when you buy brand new shit
2014-11-10T06:24:31 < dongs> just get that tablet
2014-11-10T06:24:33 < dongs> probvlme solved

2014-11-10T06:25:28 < dongs> might not :(
2014-11-10T06:25:47 < GargantuaSauce> dont you write c# all the time?
2014-11-10T06:25:55 < GargantuaSauce> java is basically the same
2014-11-10T06:26:23 < dongs> R2COM: depends if they hvae native shit. if they only have windows store apps then probly not
2014-11-10T06:26:26 < dongs> i dunno
2014-11-10T06:26:34 < dongs> for $100 i'd be tempted to try, but i still ahvcent found a usecase for a tablet
2014-11-10T06:27:34 < dongs> all my equipment is sentient. it doesntneed my control
2014-11-10T06:28:29 < dongs> drones is boring american garbage
2014-11-10T06:29:34 < englishman> lol
2014-11-10T06:29:46 < englishman> they are only for taking selfies
2014-11-10T06:29:56 < englishman> this has proved to be the biggest market
2014-11-10T06:30:14 < GargantuaSauce> no no they're called dronies dude
2014-11-10T06:30:16 < GargantuaSauce> get with the times
2014-11-10T06:30:35 < englishman> when the world has enough money to pay for it
2014-11-10T06:30:44 < GargantuaSauce> when the market realizes they have one buyer
2014-11-10T06:34:07 < dongs> impretty happy wiht 32gb

2014-11-10T06:39:05 < GargantuaSauce> i thought we made that clear sorry
2014-11-10T06:39:05 < englishman> timecube is awesome
2014-11-10T06:39:13 < englishman> so many buttons
2014-11-10T06:39:33 < dymk> GargantuaSauce, eh it's coming to me slowly
2014-11-10T06:39:54 < englishman> 5$ Arduino WiFi Module!? ESP8266 mini Tutorial/Review
2014-11-10T06:39:57 < dymk> so i almost burnt my dorm down tonight
2014-11-10T06:40:00 < dymk> in a hot oil fire
2014-11-10T06:40:00 < englishman> heh of course its arduino compatible
2014-11-10T06:40:08 < dymk> but goddamn those wings were tasty
2014-11-10T06:40:23 < dymk> sriracha + honey + buttermilk
2014-11-10T06:41:28 < dymk> why in the world would you do that
2014-11-10T06:42:10 < dymk> so many schmeckles
2014-11-10T06:42:21 < dongs> there are SPI capacitive touchscreens rihgT?
2014-11-10T06:42:53 < dongs> unfortunately i will probably need to have that shit as a strech goal
2014-11-10T06:42:56 < dymk> 1000$ is just so many schmeckles, but if you've got the dough, might as well make one hell of an apple pasty
2014-11-10T06:42:58 < dongs> those dumbperrypi idiots love touch
2014-11-10T06:44:07 < dymk> just buy 6 amazon elastic beanstalk containers
2014-11-10T06:44:48 < GargantuaSauce> how about getting a 2000W space heater and pretending it's doing all that computation
2014-11-10T06:45:15 < GargantuaSauce> use the power of ~imagination~
2014-11-10T06:45:19 < GargantuaSauce> maybe stick an rpi in there
2014-11-10T06:45:28 < dymk> mine bitcoins, symlink wallet.dat to /dev/null
2014-11-10T06:45:57 < GargantuaSauce> i overspecced it for futureproofing
2014-11-10T06:46:09 < dymk> R2COM, just giving you shit; i unno much about recent intel stuff. it's been a while since I've built a desktop
2014-11-10T06:47:00 < GargantuaSauce> i still find it pretty funny that you're actually going for ddr4
2014-11-10T06:47:47 < GargantuaSauce> you could set your sights back 6 months or so and save a lot of hookers and blow money
2014-11-10T06:48:20 < GargantuaSauce> you will always be on obsolete shit after 3 years
2014-11-10T06:48:27 < GargantuaSauce> the only question is whether you'll pay 5x as much or not
2014-11-10T06:48:34 < englishman> <GargantuaSauce> you will always be on obsolete shit after 3 years
2014-11-10T06:48:37 < englishman> more like 6 months
2014-11-10T06:48:56 < GargantuaSauce> i have ddr3 because it's well estabished commodity hardware
2014-11-10T06:49:00 < GargantuaSauce> and was cheap as fuck
2014-11-10T06:49:22 < englishman> why is it double price of 3 years ago then
2014-11-10T06:49:23 -!- djlewis [~djlewis@64-250-34-202.dyn.tcworks.net] has quit [Ping timeout: 258 seconds]

2014-11-10T06:50:40 < dongs> R in DDR stands for RAGE
2014-11-10T06:50:56 < GargantuaSauce> yeah in like 6 months to a year
2014-11-10T06:51:04 < GargantuaSauce> so wait till then
2014-11-10T06:51:51  * GargantuaSauce shrugs
2014-11-10T06:51:54 < GargantuaSauce> do what you want, man
2014-11-10T06:52:10 < GargantuaSauce> it's your money
2014-11-10T06:52:16 < GargantuaSauce> you have my opinion
2014-11-10T06:52:21 < englishman> *his russian gold
2014-11-10T06:52:29 < GargantuaSauce> it will be less ridiculously expensive
2014-11-10T06:52:35 < englishman> i dono man
2014-11-10T06:52:36 < GargantuaSauce> and maybe 16gb modules will be even available
2014-11-10T06:52:44 < englishman> RAM hasnt gone down in price for a long time
2014-11-10T06:53:19 < englishman> it really is double price now than it was 3 years ago
2014-11-10T06:53:45 < GargantuaSauce> you could probably get ddr4 chips and make your own modules
2014-11-10T06:53:47 < GargantuaSauce> have fun with that

2014-11-10T06:55:53 < englishman> do you have a favourite tool for fucking with gerbs
2014-11-10T06:58:48 < upgrdman> anyone here know xilinx fpgas? i have a nexys2 board (spartan 3e) and it has a 50MHz oscillator, and a socket for another oscillator. but then they say the DLL can multiply and divide the clock... so why would you want to install a different oscillator?
2014-11-10T06:59:14 < englishman> maybe for rtc oscillator?
2014-11-10T06:59:38 < englishman> is that oshpark
2014-11-10T06:59:58 < englishman> nice
2014-11-10T07:00:02 < GargantuaSauce> i strongly suspect it's a lot more difficult on a little module
2014-11-10T07:00:04 < englishman> cadence is pro
2014-11-10T07:04:44 < GargantuaSauce> yeah like 2.5x as much
2014-11-10T07:05:06 < GargantuaSauce> i highly doubt it's worth 2.5x as much
2014-11-10T07:05:34 < GargantuaSauce> same deal

2014-11-10T07:23:00 < englishman> well ya
2014-11-10T07:23:09 < englishman> but i meant, in modelsim
2014-11-10T07:23:14 < englishman> or is testbenches really the way
2014-11-10T07:24:32 < GargantuaSauce> probably not R2COM. i built the new machine because i needed a separate workstation. also work paid for it.
2014-11-10T07:26:12 < GargantuaSauce> i did get tempted to build a second one for myself but meh, this i7-2630qm is plenty for now

2014-11-10T07:56:42 < englishman> you could probably route that in a couple minutes

2014-11-10T07:57:01 < dongs> i think jedec or someshit has those
2014-11-10T07:57:21 < englishman> so you can spend extra money on 2nd video card

2014-11-10T08:04:38 < GargantuaSauce> yes, they're usually a bit more expensive though
2014-11-10T08:05:32 < GargantuaSauce> much like the other stuff i think >500 for one component is pushing it
2014-11-10T08:05:49 < GargantuaSauce> but my erection says otherwise
2014-11-10T08:08:43 < GargantuaSauce> i dont get why the more expensive evga one is more expensive
2014-11-10T08:08:54 < GargantuaSauce> it's got a different cooler and a couple less megahurts
2014-11-10T08:09:54 < GargantuaSauce> no 2 and 3
2014-11-10T08:10:21 < GargantuaSauce> the two evga ones are basically identical except one is $50 cheaper and a little faster

2014-11-10T08:15:00 < dymk> the usb to go plug? yeah

2014-11-10T08:46:12 < englishman> is that the year you were born
2014-11-10T08:46:21 < jadew> personally, I'm glad there's such thing as a gaming PC and crazy gamers/games that require all this stuff
2014-11-10T08:46:39 < jadew> it means there's going to be a market for PC parts for a long time
2014-11-10T08:47:18 < jadew> considering everyone is switching to tablets and netbooks, this is great for users like us

2014-11-10T08:49:08 < GargantuaSauce> also do research if you're planning to put those ssds in a raid
2014-11-10T08:49:19 < GargantuaSauce> there are a lot of configurations that make exactly zero sense
2014-11-10T08:49:36 < GargantuaSauce> ok dont even bother
2014-11-10T08:50:18 < jadew> R2COM, there are different kinds of RAID
2014-11-10T08:50:24 < jadew> most of them offer redundancy

2014-11-10T08:50:59 < jadew> no
2014-11-10T08:51:07 < jadew> having SSD + HDD in a raid would be dumb
2014-11-10T08:51:17 < jadew> because the HDD would pull the SSDs performance down
2014-11-10T08:51:30 < jadew> I'm using 2 HDDs in RAID 1 in my PC
2014-11-10T08:51:38 < jadew> RAID 1 is basically doing a mirror
2014-11-10T08:51:54 < jadew> so what gets written on one, gets written on the other one too
2014-11-10T08:52:09 < jadew> in case one of them fails
2014-11-10T08:52:36 < GargantuaSauce> with ssds if one fails it's quite likely that they all fail
2014-11-10T08:52:37 < jadew> I keep important data on that RAID
2014-11-10T08:52:42 < GargantuaSauce> yeah just have a sane backup scheme
2014-11-10T08:52:51 < jadew> but I don't need to have fast access to it
2014-11-10T08:52:59 < jadew> on a SSD you'd put your OS
2014-11-10T08:53:04 < jadew> if that fails, you don't give a crap
2014-11-10T08:53:15 < jadew> so no point of having a RAID array for that
2014-11-10T08:53:41 < jadew> why?
2014-11-10T08:53:56 < jadew> faster what? I bet they load in < 1s
2014-11-10T08:54:01 < GargantuaSauce> if they're big, yes
2014-11-10T08:54:04 < GargantuaSauce> otherwise no
2014-11-10T08:54:20 < dymk> the debugging hardware on the discovery board, would that be straightforward to also put on some custom dev board, like the micromouse PCB?
2014-11-10T08:54:34 < GargantuaSauce> dont bother dymk
2014-11-10T08:54:51 < GargantuaSauce> just put a swd header on it
2014-11-10T08:54:52 < dymk> GargantuaSauce, are better methods of debugging available?
2014-11-10T08:54:54 < dymk> oh
2014-11-10T08:54:59 < jadew> R2COM, don't know, I don't use VMs that much
2014-11-10T08:55:14 < jadew> would probably load faster
2014-11-10T08:55:26 < jadew> after all it behaves just like a PC
2014-11-10T08:55:43 < dymk> GargantuaSauce, thanks, google was actually pretty useful when given those term
2014-11-10T08:56:02 < jadew> the file is just an additional software layer between the data and the hardware
2014-11-10T08:56:09 < GargantuaSauce> and then you can use the stlink on the discovery board to debug your target dymk
2014-11-10T08:56:35 < dymk> GargantuaSauce, is that the SWD header on the discovery board?
2014-11-10T08:57:01 < GargantuaSauce> yes the 6 pin one dymk
2014-11-10T08:57:17 < dymk> great! this is turning out simpler than i thought it'd have to be

2014-11-10T09:22:34 < dongs> not if you wanna actually see the txt
2014-11-10T09:22:46 < zyp> I have no problem doing that on 1440p
2014-11-10T09:23:12 < GargantuaSauce> does adobe reader have 20% screenspace allocated to toolbars or something these days
2014-11-10T09:23:24 < GargantuaSauce> seriously i did that today with no issues
2014-11-10T09:24:26 < zyp> the latter
2014-11-10T09:24:26 < GargantuaSauce> the gpu driver is a lot smarter than you are
2014-11-10T09:24:37 < GargantuaSauce> though there is Mantle
2014-11-10T09:24:42 < GargantuaSauce> which i think is totally asinine
2014-11-10T09:25:13 < GargantuaSauce> yes
2014-11-10T09:25:21 < GargantuaSauce> well, to a greater degree
2014-11-10T09:25:44 < zyp> gpgpu APIs and graphics APIs are different
2014-11-10T09:25:51 < GargantuaSauce> extremely different
2014-11-10T09:26:19 < GargantuaSauce> no
2014-11-10T09:26:24 < zyp> no, cuda is gpgpu
2014-11-10T09:26:27 < zyp> and opencl
2014-11-10T09:26:40 < zyp> while directx and opengl is graphics
2014-11-10T09:27:52 < zyp> graphics apis are like «here's a list of points, please draw triangles between them»
2014-11-10T09:28:44 < zyp> or «run this shader program for every pixel in this triangle to determine it's color»
2014-11-10T09:29:40 < GargantuaSauce> cuda is basically just c with some specific limitations and boilerplate
2014-11-10T09:30:00 < zyp> gpgpu APIs are kinda similar, it's more «here's a function to process a piece of data, and a list of data to run it on»
2014-11-10T09:30:51 < GargantuaSauce> yeah
2014-11-10T09:30:59 < zyp> the thing GPUs are efficient at is when all cores do the same thing, just on a separate dataset each
2014-11-10T09:31:05 < GargantuaSauce> there's like 3 levels of granularity
2014-11-10T09:31:49 < GargantuaSauce> differing in data access and caching and so on
2014-11-10T09:31:58 < zyp> you can't for instance branch in a gpu function in the normal sense
2014-11-10T09:32:31 < zyp> what you have to do is do the computation for both branches, and then pick one of the results
2014-11-10T09:33:33 < zyp> oh well, time to sleep
2014-11-10T09:34:05 < GargantuaSauce> go read about it, it's complicated

2014-11-10T14:42:38 < BrainDamage> this is the internet, troll, idiot, or 13yo, the only difference is how you perceive it
2014-11-10T14:43:00 < BrainDamage> might as well have a laugh
2014-11-10T14:44:01 < madist> I like how he drew the zig zag line. I guess he thinks resistors need to be physically zig zag.
2014-11-10T14:44:11 < madist> When I was a kid I had a similar moment of confusion in math class.
2014-11-10T14:44:22 < madist> I solved a sum and got an answer in fraction and decimal.
2014-11-10T14:44:36 < BrainDamage> he claims it's a 90GHz waveguide inductor
2014-11-10T14:44:40 < madist> like 3 2/3 .6666
2014-11-10T14:45:52 < BrainDamage> also, even after being told it doesn't work, and will never work, he proceeds to ignore and keep on with his stuff
2014-11-10T14:47:26 < Steffanx> who's this guy and where can i find his work BrainDamage?
2014-11-10T14:49:18 < BrainDamage> he's a regular irc troll/kid/idiot, your call on which, so far he managed to get himself banned in 3 sep channels i lurk in, he's currently in ##rtlsdr

2014-11-11T00:07:52 < zyp> yeah, the values
2014-11-11T00:07:56 < zyp> you just said it
2014-11-11T00:09:03 < zyp> it's impossible to know why without more information
2014-11-11T00:09:19 < GargantuaSauce> very good non-answer sir 10/10
2014-11-11T00:09:34 < zyp> but my guess would be missing .data initialization
2014-11-11T00:09:59 < zyp> i.e. bad startup code
2014-11-11T00:10:17 < zyp> GargantuaSauce, thanks, I put a lot of effort into it
2014-11-11T00:10:39 < Taxman>     .data :
2014-11-11T00:10:39 < Taxman>     {
2014-11-11T00:10:39 < Taxman>         *(.data)      /* Data memory */
2014-11-11T00:10:40 < Taxman>     } >ram AT > rom
2014-11-11T00:10:50 < Taxman> you mean such a thing in my linker script?
2014-11-11T00:11:08 < Taxman>     .  = 0x20000000;  /* From 0x20000000 */
2014-11-11T00:11:14 < Taxman> this is the line before .data
2014-11-11T00:11:46 < zyp> I mean the part of the startup code that copies the contents of that sections from flash to ram
2014-11-11T00:11:54 < zyp> section*
2014-11-11T00:12:05 < Taxman> does not gcc add this code?
2014-11-11T00:12:11 < zyp> of course it doesn't
2014-11-11T00:12:53 < zyp> I mean, it's usually part of whatever runtime library you're using
2014-11-11T00:13:15 < zyp> if you're writing your own startup code, this is your own responsibility
2014-11-11T00:14:25 < Taxman> well i do not use a runtime library until now
2014-11-11T00:14:35 < Taxman> i started from a hello world example
2014-11-11T00:14:44 < Taxman> and adjusted makefile and linker script
2014-11-11T00:14:55 < Taxman> now i have my sdram and tft running :)

2014-11-11T00:46:39 < Laurenceb> isnt that the dead time?
2014-11-11T00:47:05 < mattbrejza> i dont want any deadtime
2014-11-11T00:47:28 < mattbrejza> but what actually happens is that on one edge the delay between them is zero, and the other edge 500ns
2014-11-11T00:48:32 < bvernoux> 500ns is big
2014-11-11T00:48:43 < bvernoux> what the frequency of the peripheral ?
2014-11-11T00:49:00 < mattbrejza> 48MHz
2014-11-11T00:49:02 < bvernoux> anyway it shall take 1 or 2 cycles internally
2014-11-11T00:49:17 < bvernoux> ha ok that explain 500ns
2014-11-11T00:49:35 < mattbrejza> its only a f0
2014-11-11T00:50:22 < bvernoux> it also depends on HW
2014-11-11T00:50:36 < bvernoux> how have you made the measurement ?
2014-11-11T00:51:10 < mattbrejza> scope
2014-11-11T00:52:18 < bvernoux> maybe you have resistor too
2014-11-11T00:52:31 < bvernoux> and on bad scope probe it could also add delay
2014-11-11T00:53:06 < mattbrejza> 500ns delay?
2014-11-11T00:53:24 < bvernoux> it depends on your scope ;)
2014-11-11T00:53:40 < bvernoux> if you have a 100MHz scope at 1GSPS it shall be not an issue ;)
2014-11-11T00:54:03 < bvernoux> anyway 500ns is lot of time
2014-11-11T00:54:22 < bvernoux> in theory it shall take 2 or 3 cycles => about 40ns to 60ns
2014-11-11T00:54:22 < qyx_> exchange your probes to find out
2014-11-11T00:54:26 < bvernoux> and you have 10 times more
2014-11-11T00:54:27 < qyx_> but 500ns is much

2014-11-11T00:55:56 < mattbrejza> both probes are identical delay wise
2014-11-11T00:57:34 < qyx_> have you checked values in the BDTR register?
2014-11-11T00:58:12 < mattbrejza> i dont set it, although ill explicity clear it
2014-11-11T00:58:42 < mattbrejza> originally i had used BDTR to remove the 500ns of delay, only to find out hte delay only happened on one of the edges
2014-11-11T00:59:19 < qyx_> its reset value is 0 though :S
2014-11-11T00:59:50 < scummos> did you exchange the scope channels? ;P
2014-11-11T01:00:20 < GargantuaSauce> are both gpios set to the same speed? both have roughly the same capacitance, parasitic or fet gate or whatever?
2014-11-11T01:00:22 < mattbrejza> i put both probes on the same tihng and they were identical
2014-11-11T01:00:42 < mattbrejza> yea all set the same, same hardware on the output
2014-11-11T01:00:48 < mattbrejza> the rise time is the same anyway
2014-11-11T01:02:13 < qyx_> datasheet doesn't mention that complementary outputs should be different in any way
2014-11-11T01:02:26 < qyx_> compared to "normal" timer outputs
2014-11-11T01:02:34 < qyx_> hm
2014-11-11T01:02:43 < mattbrejza> there is also ~20ns jitter on the delay between subsiquent aquistions
2014-11-11T01:02:59 < bvernoux> mattbrejza: 20ns jitter is 1 cycle @48MHz
2014-11-11T01:03:06 < bvernoux> it is normal behaviour I think
2014-11-11T01:03:11 < mattbrejza> yea i thought that might be the case
2014-11-11T01:03:19 < qyx_> try to increase prescaler & lower the freq
2014-11-11T01:03:26 < qyx_> if the delay is the same
2014-11-11T01:03:37 < Laurenceb> im talking off the top of my head here
2014-11-11T01:03:47 < mattbrejza> yea is the same
2014-11-11T01:03:49 < Laurenceb> but arent there gating delay bits?
2014-11-11T01:03:51 < bvernoux> mattbrejza: maybe pin output used have effect too
2014-11-11T01:04:05 < qyx_> wat where Laurenceb
2014-11-11T01:04:05 < bvernoux> mattbrejza: like PIN speed there is integrated filter in STM32
2014-11-11T01:04:34 < Laurenceb> i had to use those for master/slave stuff to be jitter free
2014-11-11T01:06:17 < mattbrejza> both pins should be set the same speed wise
2014-11-11T01:06:32 < bvernoux> mattbrejza: what is the localization of the pins ?
2014-11-11T01:06:53 < bvernoux> mattbrejza: as that can induce latency but not in order of more than 10ns ;)
2014-11-11T01:07:25 < mattbrejza> A8, B13
2014-11-11T01:07:35 < bvernoux> what's the package ?
2014-11-11T01:08:02 < mattbrejza> 48 qfp
2014-11-11T01:11:20 < bvernoux> B13 does not exist on this package
2014-11-11T01:11:30 < bvernoux> A8, B13 is for BGA
2014-11-11T01:11:57 < mattbrejza> as in gpiob13
2014-11-11T01:12:05 < mattbrejza> pb13
2014-11-11T01:12:15 < mattbrejza> pins 29 and 26
2014-11-11T01:12:39 < bvernoux> yes they are close
2014-11-11T01:13:01 < bvernoux> but on different port
2014-11-11T01:13:27 < bvernoux> pin29 = PA8, pin26=PB13
2014-11-11T01:13:58 < bvernoux> are you sure there is not an internal pullup/down enabled ?
2014-11-11T01:14:21 < mattbrejza> well 500ns is much longer than you would expect for an inverter, so it must be some internal coutner thing, like the deadtime gen
2014-11-11T01:14:24 < bvernoux> which could be the issue
2014-11-11T01:14:35 < mattbrejza> they both have internal pullups and are open drain
2014-11-11T01:14:47 < bvernoux> avoid internal pullups
2014-11-11T01:14:57 < bvernoux> the resistor is between 25 & 55Kohm
2014-11-11T01:15:05 < bvernoux> not accurate at all and that slow down the signal
2014-11-11T01:15:21 < bvernoux> for freq > 400KHz use external one
2014-11-11T01:15:29 < mattbrejza> oh its not internal actually
2014-11-11T01:15:44 < mattbrejza> external 10K
2014-11-11T01:15:54 < bvernoux> 10K is big for fast signal
2014-11-11T01:16:52 < mattbrejza> hmm actually you might be on to something

2014-11-11T01:21:41 < qyx_> which reminds me
2014-11-11T01:21:54 < qyx_> i should check if i can offset two timers by 1 clock cycle
2014-11-11T01:22:18 < qyx_> but i assume yes just by initializing them to x and x+1
2014-11-11T01:22:42 < qyx_> ok, answered myself
2014-11-11T01:23:26 < GargantuaSauce> hm, wouldn't you have to start them both at the same time for that to work?
2014-11-11T01:23:42 < qyx_> yes, this is possible with timer gating
2014-11-11T01:23:57 < qyx_> athough i don't know if it is 1-cycle perfect
2014-11-11T01:24:00 < mattbrejza> doesnt help that one output has a different pullup to the other...
2014-11-11T01:24:33 < GargantuaSauce> i am gonna say i called that one since the open drainness hadn't come to light yet :V
2014-11-11T01:24:34 < qyx_> mattbrejza: change them to something like 1K, it is still too much at 48MHz
2014-11-11T01:24:38 < bvernoux> qyx_: it is to output stuff ?
2014-11-11T01:24:57 < qyx_> bvernoux: 90° shifted pwm outputs

2014-11-11T01:35:19 < mattbrejza> to complicate matters an LED is involved
2014-11-11T01:36:01 < bvernoux> ha yes not good
2014-11-11T01:37:33 < bvernoux> a PMOS/NMOS transistor will be better
2014-11-11T01:37:37 < bvernoux> for safety and speed
2014-11-11T01:38:08 < bvernoux> and more current of course
2014-11-11T01:42:41 < mattbrejza> it isnt super critical anyway, ill just reduce the pullup
2014-11-11T01:43:19 < mattbrejza> its an odd waveform though, instead just the RC rise theres a 1V step, 400ns delay then the RC rise
2014-11-11T01:43:29 < mattbrejza> -> ltspice
2014-11-11T01:43:37 < bvernoux> yes ltspice rulez ;)

2014-11-11T01:44:45 < mattbrejza> that capacitance is probabily relatively insignificant compared to the led

2014-11-11T05:24:36 < madist> you got an i7 without the heatsink ?
2014-11-11T05:24:40 < madist> from ebay ?
2014-11-11T05:26:30 < madist> 500$ and they won't throw in a 10$ lump of aluminium ??
2014-11-11T05:30:45 < madist> I guess intel must be saving a shitload of money on shipping and warehousing if they don't have to ship that 800 grams of aluminium.
2014-11-11T05:31:13 < madist> wonder why they have such a big box at all. they could sell the i7 in a paper envelope.
2014-11-11T05:31:28 < madist> there are no pins to bend ...
2014-11-11T05:31:52 < madist> ok. antistatic paper packet.
2014-11-11T05:32:09 < madist> or one of those pink bubblewrap envelopes.
2014-11-11T05:32:14 < madist> they're anti-static I think.
2014-11-11T05:32:48 < BrainDamage> considering the price the cpu retails at, the box's cost even accounting for transportation, is neglectable
2014-11-11T05:33:22 < madist> BrainDamage: but the size is not. That box is so big. They could fit 100 i7's in that much space.
2014-11-11T05:33:36 < madist> they could ship the entire output of their factory in one shipping container.
2014-11-11T05:33:37 < madist> :p
2014-11-11T05:33:58 < BrainDamage> then you risk spending more in returns and failures than in shipping
2014-11-11T05:34:27 < madist> I wonder if you can buy i7s in tape and reel.
2014-11-11T05:34:31 < madist> retail.
2014-11-11T05:34:37 < madist> maybe someone on ebay.

2014-11-11T06:09:57 < upgrdman> retail packaging also has to consider theft.
2014-11-11T06:10:05 < upgrdman> small packages are easily shoved in pockets
2014-11-11T06:10:27 < upgrdman> if a thief has to unbox, it tends to happen less often
2014-11-11T06:10:36 < upgrdman> (i've worked retail...)
2014-11-11T06:11:19 < upgrdman> lol no
2014-11-11T06:13:16 < upgrdman> just finished a verilog test bench for one of my classes.
2014-11-11T06:13:38 < upgrdman> dual ethernet... you can make the box into a firewall or router...
2014-11-11T06:13:58 < upgrdman> well one port = internet
2014-11-11T06:14:04 < upgrdman> other port = LAN

2014-11-11T06:31:28 < upgrdman> iirc it depends a LOT of the design of the board. for example, intel has a good rep for doing things like having enough capacitance to do an emergency write. ocz has a rep for being cheap and cutting corners.
2014-11-11T06:31:54 < upgrdman> even pc i own has an SSD in it, never had one failure
2014-11-11T06:31:57 < upgrdman> but i use UPSs
2014-11-11T06:32:08 < upgrdman> ocz = a brand that makes SSDs.
2014-11-11T06:32:26 < upgrdman> i have an ocz ssd, it works fine, but they have a bad reputatio
2014-11-11T06:33:26 < upgrdman> doubt it
2014-11-11T06:34:10 < upgrdman> i just bought UPSs because it's rage-inducing when you work on something for hours, and the power cuts or flickers before you save.
2014-11-11T06:34:32 < upgrdman> and UPSs last forever. i have one i bought in the late 90's
2014-11-11T06:34:42 < upgrdman> just replace batteries every 3-4 years.
2014-11-11T06:35:06 < madist> I used to have a UPS. Then I discovered that putting in a 680uF capacitor in the PC gives me more holdup time.
2014-11-11T06:35:54 < upgrdman> they did at least. haven't bought an SSD in years.
2014-11-11T06:36:08 < upgrdman> i have 2 or 3 of the old intel 80GB ssds
2014-11-11T06:36:16 < upgrdman> first one i bought was like $400
2014-11-11T06:36:29 < upgrdman> and it's was night and day, so i bought more as the prices dropped.
2014-11-11T06:36:53 < upgrdman> always used UPS
2014-11-11T06:37:03 < upgrdman> i've used UPS since win98se-era
2014-11-11T06:38:00 < madist> R2COM: no mica ?
2014-11-11T06:39:02 < upgrdman> i still have my 98se and 95 CD-ROMs
2014-11-11T06:39:15 < upgrdman> i toss my 3.1 floppies :( regrets
2014-11-11T06:39:36 < upgrdman> i have ibm dos 2.0 or 2.1
2014-11-11T06:39:52 < upgrdman> binder of docs + 5.25" floppies.
2014-11-11T06:40:55 < madist> R2COM: you're on the wrong track. You need to be googling mains capacitors.
2014-11-11T06:41:06 < madist> 680uF cap is on the mains.
2014-11-11T06:41:11 < upgrdman> what kind of capacitance do those "stiffening" car audio caps have? you know, the ones blacks and mexicans put next to their shit amps in the trunk
2014-11-11T06:41:35 < madist> few farads on the label
2014-11-11T06:44:15 < upgrdman> do it
2014-11-11T06:45:00 < upgrdman> an UPS is good regardless of SSD usage. who the fuck wants their box to die if the power goes out or flickers
2014-11-11T06:45:20 < upgrdman> R2COM: you can config the os to shitdown when ups battery is low
2014-11-11T06:45:59 < upgrdman> an UPS with dual 12V 7A gel cells will give an idle box like 30mins of run time
2014-11-11T06:46:30 < upgrdman> i have one of those just powering my modem+router+dingleberryPi... good for like 6 hours :)
2014-11-11T06:46:55 < upgrdman> connect anything to it that you don't want to cut out. if you NEED both monitors, do it. or just one.
2014-11-11T06:47:01 < madist> why waste energy in the UPS when you can wire a 12V gel cell directly to the raspi ?
2014-11-11T06:47:28 < upgrdman> im tempted to do that in a way. battery -> 5V smps -> router/modem/pi
2014-11-11T06:47:39 < upgrdman> but too lazy. and already have the spare UPS
2014-11-11T06:48:19 < madist> the smallest UPS is 1000W I think ?
2014-11-11T06:48:19 < upgrdman> seems ok, but never used that brand

2014-11-11T06:48:56 < upgrdman> well i've never had a problem, too small of a sample size... but i have an APC and a belkin. i don't think belkin still does UPSs

2014-11-11T06:54:28 < upgrdman> no, not with the pi
2014-11-11T06:55:33 < upgrdman> 3.5W... one month is 2.6kWh which is about $0.38

2014-11-11T07:02:32 < upgrdman> so don't skimp. buy a good one.
2014-11-11T07:04:48 < upgrdman> well a 900w psu isn't necessarily a 900w psu. marketing love to over-rate their trash
2014-11-11T07:05:48 < upgrdman> "it's 900W, i promise" ... but the heatsinking is just enough to keep it 5C below absolute maximum IC ratings

2014-11-11T07:06:30 < upgrdman> and the caps are made by some chinese dude in his backyard

2014-11-11T08:03:06 < dongs> there's not a single voltage > 3.3V
2014-11-11T08:03:07 < dongs> does it?
2014-11-11T08:03:14 < dongs> CPU Vcore is at like 0.xxV isnt it?
2014-11-11T08:03:34 < zyp> yes, but it's fed from regs on the motherboard, running off 12V
2014-11-11T08:03:37 < BrainDamage> the vcore is generated from a dcdc from an higher voltage
2014-11-11T08:03:38 < zyp> same for the gpu
2014-11-11T08:03:57 < dongs> shouldnt it be greneated from 5V or 3.3V?
2014-11-11T08:03:58 < jpa-> yeah, pretty much everything high-power is from 12V
2014-11-11T08:04:01 < jpa-> harddrives also
2014-11-11T08:04:10 < jpa-> dongs: need less wires for 12V
2014-11-11T08:04:12 < zyp> dongs, no, it's 12V because it's more efficient
2014-11-11T08:04:21 < zyp> older ATX standards had it on 5V
2014-11-11T08:04:26 < zyp> but nowadays it's all 12V

2014-11-11T08:47:02 < PaulFertser> My coworker told me yesterday an innovation story. When he was a schoolboy he once turned the whole kitchen into a giant coil, connected it to "wired radio" outlet via a random transformer, then made a several thousands coil on a ferrite and connected it to headphones. It "worked" surprisingly well, he could hear the voice just fine :)
2014-11-11T08:49:15 < englishman> i hear voices all the time, am i innovative too
2014-11-11T08:51:10 < PaulFertser> I'm not sure if it was common in any other countries but here we still have all the multi-apartments houses equipped with a wired network for voice broadcast (one unmodulated + 4 additional AM channels).
2014-11-11T08:52:36 < dongs> englishman: charger works
2014-11-11T08:53:09 < jpa-> that giant coil thing (induction loop) was used around here in many classrooms to provide amplified voice for hearing aids
2014-11-11T08:53:24 < jpa-> not sure if anyone ever actually used it, or atleast doesn't use it anymore

2014-11-11T11:06:26 < madist> you hold your phone steady while pointing it directly at a basestation ?
2014-11-11T11:08:26 < jpa-> the problem in that case is just to avoid the tx antenna from saturating the rx antenna in the near field; i guess that is what they have figured out
2014-11-11T11:08:50 < jpa-> circular polarisation is used for the same purpose in laser systems
2014-11-11T11:09:42 < madist> i don't understand.
2014-11-11T11:09:52 < madist> the circulator is on the other side of the tx rx antennas
2014-11-11T11:10:01 < madist> how can it prevent the rx from getting saturated by tx ?
2014-11-11T11:10:15 < jpa-> an antenna is just a impedance matcher between vacuum (air) and circuit
2014-11-11T11:10:25 < jpa-> or a connection point
2014-11-11T11:10:51 < jpa-> if the antenna is really well designed, it will not reflect back much of the tx energy.. and perhaps they filter the small amount away somehow
2014-11-11T11:11:14 < jpa-> so then their circulator splits the wave coming back into the rx circuit, while the tx wave goes straight
2014-11-11T11:12:15 < madist> doesn't make sense to me
2014-11-11T11:12:33 < jpa-> ask r2com to explain ;)

2014-11-11T12:45:30 < dongs> mgiht have native keil supporrt which is a plus
2014-11-11T12:45:41 < dongs> typical opensores shit you usually gotta dig through 100 makefiles
2014-11-11T12:46:02 < tkoskine> mbed provides library and also some helper firmwares/tools to get your binaries to the mbed compatible boards easily.
2014-11-11T12:46:51 < madist> mbed OS ?
2014-11-11T12:46:58 < tkoskine> They also have web-based code editor, but I prefer to get the sdk from github and compile it by myself (from the command line).
2014-11-11T12:47:49 < tkoskine> https://github.com/mbedmicro/mbed - mbed sdk
2014-11-11T12:49:16 < madist> this is nice. I have a LPC xpresso board in a drawer somewhere.
2014-11-11T12:49:40 < dongs> mbed is filthy c++
2014-11-11T12:49:43 < dongs> if you care about that.
2014-11-11T12:50:06 < tkoskine> Looks like they have changed their web site (mbed.org) recently. Some time ago, mbed.org provided "developer friendly" site, but now that is at http://developer.mbed.org/
2014-11-11T12:51:49 < jpa-> comparing stm32cube and stdperiph is a bit like comparing horse poo to bullshit
2014-11-11T12:52:03 < jpa-> pick either, but neither is good

2014-11-11T13:47:25 < tecdroid_> can someone tell me where to find an implementation for the st appnote on eeprom emulation? didn't find it anywhere. I'm using an stm32f103
2014-11-11T13:48:59 < dongs> you dont need it
2014-11-11T13:49:05 < dongs> their "emulation" is fucking bloated shit
2014-11-11T13:49:27 < tecdroid_> okay.. then.. tell me how to persist data

2014-11-11T15:00:24 < tecdroid_> is it really neccessary to make these flash read mechanisms that safe? switching banks, multiple reads, etc..
2014-11-11T15:00:30 < tecdroid_> write mechanism..
2014-11-11T15:00:46 < jpa-> what flash write mechanisms?
2014-11-11T15:01:05 < jpa-> some of them have extra stuff so that you can keep running while flashing
2014-11-11T15:03:38 < madist> always a good idea to keep running while flashing
2014-11-11T15:04:17 < jpa-> well if you are a woman it can be somewhat uncomfortable

2014-11-11T15:18:01 < dongs> welll wtf
2014-11-11T15:18:13 < dongs> CR2032 in my uCurrent ran flat
2014-11-11T15:18:15 < dongs> and it was off!
2014-11-11T15:22:09 < dongs> what the fuck hwo do i use this hsit
2014-11-11T15:22:28 < jpa-> smear it on ur face
2014-11-11T15:23:25 < dongs> thats hilarious it comes wiht liek20 pages .pdf that talks about everything except how to use it
2014-11-11T15:23:29 < dongs> http://alternatezone.com/electronics/ucurrent/uCurrentArticle.pdf
2014-11-11T15:23:55 < dongs> the only picture of it showing device under test doesn't show where the wires go
2014-11-11T15:24:15 < dongs> and by wire thickness it looks like it connects multimeter to current input probes..............................
2014-11-11T15:24:32 < jpa-> well it is quite trivial
2014-11-11T15:24:33 < bvernoux> dongs: I have 2 of that
2014-11-11T15:24:40 < dongs> bvernoux: then tell me how to fucking use it
2014-11-11T15:24:47 < dongs> jpa-: not obvious to me, especially after looking at htat pic.
2014-11-11T15:24:54 < madist> Dave sold you a new one with a bad battery ?
2014-11-11T15:24:55 < bvernoux> dongs: just plug it like an ammeter
2014-11-11T15:25:05 < bvernoux> and the output is mV, uV ... depending on the caliber
2014-11-11T15:25:10 < jpa-> dongs: the pic is strange yeah
2014-11-11T15:25:15 < dongs> the pic is fucked
2014-11-11T15:25:20 < bvernoux> there is Current Input
2014-11-11T15:25:23 < jpa-> dongs: looks shopped
2014-11-11T15:25:23 < madist> its a current to voltage converter. what's there to explain ?
2014-11-11T15:25:26 < bvernoux> and Voltage Output
2014-11-11T15:25:41 < bvernoux> if you choose 1mV/nA 10K
2014-11-11T15:25:42 < jpa-> different photo of multimeter pasted on top
2014-11-11T15:25:55 < bvernoux> when in In you consume 1nA you have 1mV as output
2014-11-11T15:26:01 < dongs> what do i do, interrupt high side and feed it through the current input?
2014-11-11T15:26:16 < jpa-> you can put it on high side or low side, whatever you want
2014-11-11T15:26:22 < madist> current measurement generally requires you to interrupt the circuit.
2014-11-11T15:26:24 < jpa-> and yeah, feed through the current input
2014-11-11T15:26:50 < bvernoux> dongs: just plug Current Input like on a Multimeter in Ampereter mode
2014-11-11T15:27:03 < bvernoux> all is analog behind ...
2014-11-11T15:27:06 < dongs> i think im gonna send dave "annoyingfuck" jones a rageemail
2014-11-11T15:27:29 < bvernoux> if you have very fast current switching the uCurrent is useless
2014-11-11T15:27:39 < bvernoux> as it does not average the data ...
2014-11-11T15:27:53 < madist> Dave must be getting rid of his used CR2032's by putting them in the uCurrent devices he sends out.
2014-11-11T15:27:53 < bvernoux> and BW is limited to 2MHz IIRC
2014-11-11T15:28:11 < jpa-> bvernoux: wouldn't it automatically be averaging over the bw?
2014-11-11T15:28:19 < dongs> isnt that good... ?
2014-11-11T15:28:19 < jpa-> dongs: he'll send you a video reply in whining voice
2014-11-11T15:28:26 < bvernoux> jpa-: in fact it does not
2014-11-11T15:28:27 < dongs> jpa-: yea no thanks
2014-11-11T15:28:31 < jpa-> bvernoux: why not?
2014-11-11T15:28:43 < jpa-> bvernoux: or rather, how can you build it so that it doesn't?
2014-11-11T15:28:45 < bvernoux> jpa-: tested on LPC4370 @ 200MHz with sleep/wake up ;)
2014-11-11T15:28:59 < bvernoux> and the output was not usable and totally wrong
2014-11-11T15:29:09 < jpa-> maybe it was your multimeter that is not averaging?
2014-11-11T15:29:18 < bvernoux> because of huge peak on current when wakeup ...
2014-11-11T15:29:22 < jpa-> or did you look at it with a scope?
2014-11-11T15:29:28 < bvernoux> jpa-: I do not use multimeter but scope
2014-11-11T15:29:43 < jpa-> and the integral was inaccurate?
2014-11-11T15:29:51 < bvernoux> anyway also it requires very good banana plug especially to avoid adding resistor
2014-11-11T15:30:00 < madist> when you bought the uCurrent did you get your free copy of "Internet Dating Book" ?
2014-11-11T15:30:13 < bvernoux> jpa-: output was saturated to 800mA ...
2014-11-11T15:30:19 < dongs> it doesnt do shit
2014-11-11T15:30:21 < dongs> wtf
2014-11-11T15:30:26 < jpa-> bvernoux: ah, so you saturated it and it got saturated?
2014-11-11T15:30:29 < bvernoux> anyway for most common hw it works
2014-11-11T15:30:31 < jpa-> no surprise there
2014-11-11T15:30:41 -!- phantoxe [~destroy@2a02:4780:1:1::1:123c] has joined ##stm32
2014-11-11T15:30:43 < bvernoux> jpa-: no real current was < 400mA
2014-11-11T15:30:51 < jpa-> bvernoux: what about peak current?
2014-11-11T15:31:05 < bvernoux> jpa-: but too fast switch from 80mA to 380mA was not working with it
2014-11-11T15:31:28 < bvernoux> especially I have tested with with dual core M4F + M0 sleep / wakeup
2014-11-11T15:32:03 < bvernoux> with a multimeter it compute average current, which is not what does uCurrent
2014-11-11T15:32:30 < dongs> so in 1mV/uA mode
2014-11-11T15:32:34 < dongs> im reading -1.5V
2014-11-11T15:32:42 < dongs> 15mA?
2014-11-11T15:32:55 < jpa-> 1500uA = 1.5mA
2014-11-11T15:32:56 < bvernoux> 1500uA
2014-11-11T15:32:59 < bvernoux> yes
2014-11-11T15:33:00 < dongs> uh
2014-11-11T15:33:05 < dongs> that cant be right
2014-11-11T15:33:07 < dongs> i have 3 leds blinking
2014-11-11T15:33:11 < dongs> + mcu running
2014-11-11T15:33:11 < bvernoux> you just need to reverse Input + / - to have positive current
2014-11-11T15:33:14 < jpa-> maybe it is saturated
2014-11-11T15:33:20 < jpa-> 1.5V for the output is quite large
2014-11-11T15:33:22 < dongs> its in negative
2014-11-11T15:33:25 < bvernoux> use 1mV/mA
2014-11-11T15:33:26 < jpa-> switch to smaller range
2014-11-11T15:33:29 < dongs> lemme try swsapping +/-
2014-11-11T15:33:29 < bvernoux> else you will burn it
2014-11-11T15:34:29 < dongs> in 1mV/mA it barely reads anything
2014-11-11T15:34:46 < bvernoux> MCU + 3 LEDS shall be something like 100mA
2014-11-11T15:34:53 < bvernoux> depending on resistor & MCU freq
2014-11-11T15:35:01 < jpa-> dongs: then switch your multimeter to mV range
2014-11-11T15:35:09 < dongs> well im using scope
2014-11-11T15:35:12 < dongs> cant find my fucking fluke
2014-11-11T15:35:17 < jpa-> then switch your scope to mV range
2014-11-11T15:35:21 < dongs> it is
2014-11-11T15:35:26 < dongs> its 500mV/div
2014-11-11T15:35:32 < dongs> and its ~exactly 3 div up
2014-11-11T15:35:33 < bvernoux> you have selected +/- 0-1250µA (10µV / uA burden voltage)
2014-11-11T15:35:34 < jpa-> it doesn't have lower than that?
2014-11-11T15:35:41 < dongs> yes, it does, then it clips
2014-11-11T15:35:42 < bvernoux> it was totally saturated
2014-11-11T15:35:51 < bvernoux> you are lucky if precision resistor is not dead
2014-11-11T15:36:05 < jpa-> dongs: switch to 1mV/mA and 5mV/div or similar
2014-11-11T15:36:17 < bvernoux> there is only 3 div
2014-11-11T15:36:27 < bvernoux> for safety already use +/- 0-1250mA (20µV / mA burden voltage typical)
2014-11-11T15:36:35 < bvernoux> 1mV/mA
2014-11-11T15:36:46 < bvernoux> already->always
2014-11-11T15:37:32 < bvernoux> anyway 1mV/mA is very sensitive to resistor of wire
2014-11-11T15:37:57 < dongs> i dont see it doing anything useful
2014-11-11T15:38:12 < dongs> at 1mV/mA theres a spike then it goes to super low
2014-11-11T15:38:19 < bvernoux> personnaly I will advice VICTOR 86D ;)
2014-11-11T15:38:40 < bvernoux> up to 600mA with good accuracy and it is a full multimeter
2014-11-11T15:39:55 < jpa-> dongs: what is super low? it should be about ~10mV, depending on your draw
2014-11-11T15:40:02 < dongs> http://i.imgur.com/W36wsa1.png
2014-11-11T15:40:25 < jpa-> so 158mV = 158mA, looks correct
2014-11-11T15:40:35 < jpa-> err
2014-11-11T15:40:38 < dongs> gotta find my multimeter.
2014-11-11T15:40:48 < dongs> this scope shit isnt gonna wo rk
2014-11-11T15:41:12 < jpa-> where does it tell the current level?
2014-11-11T15:41:33 < qyx_> i didnt read the whole conversation
2014-11-11T15:41:33 < qyx_> but
2014-11-11T15:41:56 < qyx_> i hope you arent measuring a device connected to the same ground
2014-11-11T15:42:06 < dongs> device is on battery actually
2014-11-11T15:42:10 < qyx_> ok
2014-11-11T15:42:12 < dongs> im checking how much the dildo is drawing
2014-11-11T15:42:25 < dongs> it has no common ground with anything
2014-11-11T15:43:12 < bvernoux> anyway uCurrent is interesting mainly for ultra low power stuff
2014-11-11T15:43:29 < dongs> k, 17mV
2014-11-11T15:43:34 < dongs> in 1mV/mA mode
2014-11-11T15:43:39 < dongs> so 17mA?
2014-11-11T15:43:49 < bvernoux> yes
2014-11-11T15:43:59 < dongs> thats pretty amazing if true
2014-11-11T15:44:13 < bvernoux> and with scope ?
2014-11-11T15:44:38 < dongs> well scope has noise like crazy at that level
2014-11-11T15:45:00 < bvernoux> ha yes 17mV is not a lot ...
2014-11-11T15:45:34 < qyx_> mcu + 3 leds?
2014-11-11T15:45:45 < dongs> http://i.imgur.com/RMAzRos.jpg
2014-11-11T15:45:46 < dongs> dunno man
2014-11-11T15:46:19 < bvernoux> try to measure it with ampermeter mode with multimeter to check ;)
2014-11-11T15:46:35 < dongs> it only has dc amps
2014-11-11T15:46:39 < dongs> i doubt it will even touch it
2014-11-11T15:47:09 < bvernoux> I can show you measurement on HydraBus ;)
2014-11-11T15:47:22 < bvernoux> I know it is 0.8A over 5V
2014-11-11T15:47:38 < dongs> hm, ok, 1mV/uA shows it drawing 4.4uA
2014-11-11T15:47:53 < qyx_> even better
2014-11-11T15:48:00 < dongs> when its off
2014-11-11T15:49:47 < dongs> bvernoux: i'd be more intersted in current consumption of airspy.
2014-11-11T15:50:40 < bvernoux> dongs: 380mA max

2014-11-11T15:55:34 < bvernoux> 349mV ;)

2014-11-11T16:21:20 < qyx_> which one?
2014-11-11T16:21:24 < dongs> nrf51
2014-11-11T16:21:28 < qyx_> F401 was about the same
2014-11-11T16:21:38 < dongs> i didnt turn on any power managemetn shit
2014-11-11T16:21:44 < dongs> or suspend etc mode.
2014-11-11T16:21:44 < qyx_> yep, me neigher
2014-11-11T16:22:29 < qyx_> it was like 3-4mA on 21MHz
2014-11-11T16:22:42 < qyx_> better uA/MHz ratio than L1
2014-11-11T16:26:43 < bvernoux> dongs: so you see uCurrent works ;)
2014-11-11T16:33:41 < Steffanx> ofcourse it works.
2014-11-11T16:34:15 < bvernoux> my 1st is already out of battery ;)
2014-11-11T16:34:24 < bvernoux> led is blinking ...
2014-11-11T16:34:28 < dongs> mine was out of battery before i even used it
2014-11-11T16:34:58 < bvernoux> would have been better with AA or AAA batteries
2014-11-11T16:35:10 < bvernoux> it is possible to do it need hacking ...
2014-11-11T16:35:11 < Steffanx> mine is out of battery all the time, .. because i forget to turn it off :D
2014-11-11T16:35:14 < dongs> that document mentions that
2014-11-11T16:35:21 < dongs> it fits some "3AAA holder" inside the case
2014-11-11T16:36:07 < bvernoux> dongs: yes but need a hack to do it would have been better for the price to include it
2014-11-11T16:37:13 < dongs> i dont dare measuring the "off" current of the old dildo that im fixing
2014-11-11T16:37:24 < dongs> since there it just put stm8l into wfi()
2014-11-11T16:37:32 < dongs> and had battery voltage dropped through diodes

2014-11-11T16:48:17 < dongs> powered off
2014-11-11T16:48:28 < dongs> i should probly take that CR2032 out of it
2014-11-11T16:48:36 < dongs> or else it'll discharge by itself just from sitting there
2014-11-11T16:48:41 < bvernoux> yes else in 3 weeks it will be dead ;)
2014-11-11T16:48:42 < dongs> no idea how that happened, its completely flat.
2014-11-11T16:48:45 < dongs> why?
2014-11-11T16:48:50 < dongs> doesnt the switch power it off?
2014-11-11T16:49:03 < bvernoux> my 2 uCurrent CR2032 are dead and switch was OFF
2014-11-11T16:49:33 < dongs> well, thats waht i see.

2014-11-11T20:53:14 < Steffanx> no, but i was surprised to see that.
2014-11-11T20:53:17 < Steffanx> just suprised
2014-11-11T20:53:41 < zyp> not sure who you refer to, considering there's multiple persons with that name on g+

2014-11-11T21:15:32 < PaulFertser> zyp: a magic c++ question: http://paste.debian.net/131336/
2014-11-11T21:17:18 < jpa-> emplace is not same as add?
2014-11-11T21:17:51 < PaulFertser> It's about the same, just avoids unnecessary copy by constructing in place.
2014-11-11T21:18:00 < zyp> PaulFertser, what is the question?
2014-11-11T21:18:05 < jpa-> yes, constructing something else than x
2014-11-11T21:18:14 < PaulFertser> zyp: what magic() returned.
2014-11-11T21:18:37 < zyp> ah
2014-11-11T21:18:47 < jpa-> x_type is just something that constructs to different than what its constructor takes as argument
2014-11-11T21:18:52 < zyp> I'll look at it later, got to go to the airport now
2014-11-11T21:19:18 < PaulFertser> zyp: have a nice trip!
2014-11-11T21:19:26 < jpa-> class magic { magic(const magic &foo) {} bool operator==() const { return false; }};
2014-11-11T21:19:47 < PaulFertser> jpa-: there was assert that would trigger for a class
2014-11-11T21:19:48 < jpa-> though apparently line 9 contradicts that
2014-11-11T21:19:52 < PaulFertser> Yep
2014-11-11T21:20:04 < jpa-> maybe NaN?
2014-11-11T21:20:45 < PaulFertser> jpa-++
2014-11-11T21:21:21 < PaulFertser> jpa-: I couldn't get it when I was asked but I was close remembering that on x86 double is sometimes not equal to itself.

2014-11-12T03:27:59 < kakeman> ok
2014-11-12T03:32:35 < englishman> The selected build of GDB does not support Python scripting.
2014-11-12T03:32:41 < englishman> so close and yet
2014-11-12T03:32:45 < englishman> lunix'd
2014-11-12T03:32:53 < dongs> who the fuck needs python with gdb
2014-11-12T03:33:09 < englishman> he latest version of QtCreator does not support gdb without python, so you need to install Ubuntu package or build gdb with python support

2014-11-12T05:26:18 < upgrdman> R2COM: what does "r2com" signify? an abbrevion?
2014-11-12T05:26:23 < upgrdman> abbreviation even
2014-11-12T05:32:14 < GargantuaSauce> definitely is more opaque than "he who upgrades"
2014-11-12T05:32:47 < GargantuaSauce> not that important then is it
2014-11-12T05:33:10 < GargantuaSauce> no you hold it in there with a nice insulative layer of hot glue
2014-11-12T05:33:55 < GargantuaSauce> usually the case's motherboard tray has standoffs and they are metal
2014-11-12T05:34:01 < upgrdman> the case and mobo usually come with brass ones
2014-11-12T05:34:24 < upgrdman> i have line a billion ones left over from my upgrading adventures
2014-11-12T05:34:38 < upgrdman> i think i started to throw them away even
2014-11-12T05:35:24 < BrainDamage> it's been almost a decade since I assembled pcs, if it's still the case, double check the motherboard standoff holes vs the case
2014-11-12T05:35:29 < ds2> people still assemble their own PCs?
2014-11-12T05:35:53 < BrainDamage> there were more holes on the case to match multiple motherboards, and putting the wrong standoff might mean frying the motherboard
2014-11-12T05:36:18 < BrainDamage> just place on top of the panel and mark the holes
2014-11-12T05:36:39 < BrainDamage> the ones you see trough the motherboard mounting holes are the correct ones ...
2014-11-12T05:36:43 < upgrdman> be a man. secure your motherboard with hot melt glue and zip ties.
2014-11-12T05:37:55 < upgrdman> nice demo model:  http://i.imgur.com/8HtIAp7.jpg
2014-11-12T05:38:21 < GargantuaSauce> that is a weird looking candle
2014-11-12T05:38:31 < upgrdman> ya. funny how the wick burned, huh?
2014-11-12T05:39:55 < GargantuaSauce> if you can think of it, it probably exists
2014-11-12T05:40:10 < upgrdman> R2COM: just for you:  http://i.imgur.com/CAGGdHo.jpg
2014-11-12T05:40:33 < dongs> sounds japanese
2014-11-12T05:40:33 < upgrdman> that one simulates a hole that doesn't even exist in most people
2014-11-12T05:40:59 < GargantuaSauce> that image shows that the converse of my statement is a falsehood
2014-11-12T05:41:00 < gxti> this is what innovation looks like
2014-11-12T05:41:10 < upgrdman> GargantuaSauce: indeed
2014-11-12T05:41:33 < GargantuaSauce> that foot does not have bluetooth

2014-11-12T05:42:11 < upgrdman> i remember taking a psychology class. the professor asked what the point of high heels was. some young girl chimed in "it positions the feet in the position they would be in when you orgasm" ... most awkward glances were had after that gem.
2014-11-12T05:42:40 < BrainDamage> what does bluetooth connectivity provides? battery charge, intensity and probably waveform type, anything else?

2014-11-12T06:00:31 < upgrdman> they're poking a waveguide, right?  https://www.youtube.com/watch?v=82s5Q3GIO9I
2014-11-12T06:03:12 < BrainDamage> that tard is poking an high power am trasmitter
2014-11-12T06:03:16 < BrainDamage> he's poking the mast
2014-11-12T06:04:22 < BrainDamage> the ^2 of conversion from voltage to power downshifts the signal to baseband, and the heat directly couples as pressure waves in air
2014-11-12T06:05:02 < BrainDamage> in short the tard was cooking half oh his body to power that
2014-11-12T06:05:11 < upgrdman> nice
2014-11-12T06:05:20 < upgrdman> mast != waveguide?
2014-11-12T06:05:28 < BrainDamage> mast = antenna
2014-11-12T06:05:45 < upgrdman> oh ok
2014-11-12T06:05:46 < BrainDamage> a waveguide tries to keem a wave confined, an antenna does the opposite, it tries to radiate it
2014-11-12T06:05:58 < upgrdman> gotcha thanks
2014-11-12T06:06:21 < BrainDamage> when the whole structure is the antenna itself, it's a mast
2014-11-12T06:06:29 < BrainDamage> it's insulated from ground with those pylons
2014-11-12T06:06:38 < BrainDamage> otherwise it'd have huge losses
2014-11-12T06:07:02 < BrainDamage> and they are generally powered at stupid voltages / powers in order to broadcast far
2014-11-12T06:07:14 < BrainDamage> like 100kW is not a uncommon
2014-11-12T06:08:19 < upgrdman> what kind of V?
2014-11-12T06:09:24 < BrainDamage> sqrt(100kW*377Ohm) and you'll know the peak v
2014-11-12T06:09:33 < upgrdman> why 377
2014-11-12T06:10:40 < BrainDamage> it's vacuum's characteristic impedance
2014-11-12T06:11:08 < BrainDamage> an antenna is nothing more than a giant resonating transformer that matches the waveguide's characteristic impedance to vacuum's
2014-11-12T06:13:30 < madist> hmm... http://en.wikipedia.org/wiki/Ampere#Proposed_future_definition

2014-11-12T06:15:01 < BrainDamage> the ampère definition is shit, you need infinitely long wires according to the definition, as far as I know the idea is instead slave the ampere to the volt and make the volt as base unit
2014-11-12T06:15:24 < BrainDamage> using stacked josephson junctions
2014-11-12T06:16:04 < BrainDamage> the thing with SI is that not only the ease of calculations is accounted, but also how to reproduce it with best possible accuracy
2014-11-12T06:16:24 < BrainDamage> typically everything's referred to time if possible because it's the most accurate thing we can measure
2014-11-12T06:16:52 < BrainDamage> and then there's the asshole of the mass ...
2014-11-12T06:18:03 < BrainDamage> didn't he already built a small one?
2014-11-12T06:18:39 < upgrdman> i never really made one. i just stuck an rf module on my pcb.
2014-11-12T06:18:43 < upgrdman> cc2500, $2, done.
2014-11-12T06:18:52 < upgrdman> i would like to learn RF properly one day
2014-11-12T06:19:07 < BrainDamage> weren't you the guy that made the induction heater?
2014-11-12T06:19:12 < upgrdman> i did
2014-11-12T06:19:20 < upgrdman> it works well now. melt aluminum
2014-11-12T06:19:47 < upgrdman> tempted to build a proper (not self-oscillating) one if i get the time and motivation
2014-11-12T06:19:53 < BrainDamage> change the coil to a different shape optimized to radiate your frequency and you'll bring all the police to the yard
2014-11-12T06:20:06 < upgrdman> what shape?
2014-11-12T06:20:23 < upgrdman> 1/4 wavelength?
2014-11-12T06:20:25 < BrainDamage> what frequency is it oscillating at atm?
2014-11-12T06:20:31 < upgrdman> 60ish kHz
2014-11-12T06:20:54 < BrainDamage> making an efficient radiator at that frequency without fancy materials will be painful
2014-11-12T06:21:03 < BrainDamage> blame c being stupidly high
2014-11-12T06:21:08 < upgrdman> ok. let's say 1MHz
2014-11-12T06:21:34 < BrainDamage> that's still like 100m for an ideal antenna arm
2014-11-12T06:21:45 < upgrdman> antenna shape being?
2014-11-12T06:21:49 < upgrdman> just a line
2014-11-12T06:21:53 < upgrdman> a coil?
2014-11-12T06:22:01 < upgrdman> a dildo shape?
2014-11-12T06:22:05 < BrainDamage> 2 arms of equal length each long half of the wavelength
2014-11-12T06:22:09 < BrainDamage> err, 1/4
2014-11-12T06:22:17 < BrainDamage> that's one of the simplest you ccan build
2014-11-12T06:22:27 < BrainDamage> you can actually get away with making the antenna shorter
2014-11-12T06:22:40 < upgrdman> i don't want to be a pest
2014-11-12T06:22:48 < BrainDamage> and artifically change the impedance with LC networks

2014-11-12T06:23:24 < BrainDamage> there's actually frequency bands where everyone is free to transmit within certain rules
2014-11-12T06:23:35 < BrainDamage> look up a table for your country
2014-11-12T06:23:36 < upgrdman> is that the 1/2pi*sqrt(lc)
2014-11-12T06:24:44 < BrainDamage> I have no idea, check local legislation
2014-11-12T06:25:25 < BrainDamage> you'll likely need a certification of conformity
2014-11-12T06:25:28 < BrainDamage> which costs
2014-11-12T06:25:54 < BrainDamage> transmitting on a restricted band would require that AND a license to transmit
2014-11-12T06:26:14 < gxti> they are unlicensed bands, it doesn't mean you can sell products that operate there without certification, just that operators (users) don't need a license to use it
2014-11-12T06:27:02 < gxti> hmm, very smart
2014-11-12T06:28:31 < dongs> fucking shit spent like 30 minutes figuring out why i wasnt getting usart_ck out of a pin, apparently ST decided to get smart and STM8S003K3 and F3 have different pinout for peripherals

2014-11-12T06:30:32 < upgrdman> anyone here know verilog?
2014-11-12T06:31:41 < upgrdman> in my top file, i instantiated a module, but used an invalid name for one of the inputs. no error, just Z's and X's in simulation. why no warning or error for invalid identifiers?

2014-11-12T06:33:05 < upgrdman> no, just a typo. like an input was named r2com and i wrote r2con by accident.
2014-11-12T06:33:55  * upgrdman tries to reproduce problem
2014-11-12T06:35:56 < upgrdman> ya. no error. i even make up a name, SHITSHITSHITGUYS, and it fucking passed Behavioral Syntax Check, and sim shits the bed with Z's and X's

2014-11-12T07:42:43 < doelie> hi. anyone know if it's possible to set breakpoint registers from inside the machine as opposed to jtag/sw? i'm writing a special purpose gdb stub and was wondering if this even makes sense.
2014-11-12T07:43:31 < doelie> particular machine is stm32f103c8
2014-11-12T07:45:48 < dongs> lol how do you even expect that to work
2014-11-12T07:49:21 < doelie> i wonder if there's a way to trap into a signal handler
2014-11-12T07:50:02 < doelie> from outside it traps into halt which is.. not so useful :)
2014-11-12T07:50:52 < dongs> cortex has an actual proper debug unit
2014-11-12T07:51:08 < doelie> yeah i know though i need something from inside
2014-11-12T07:51:50 < doelie> like on i386: hw breakpoint -> int3
2014-11-12T07:52:33 < dongs> cortex FPB is unrelated from what is in actual code
2014-11-12T07:52:43 < dongs> when it hits the addres,s it returns BPKT to the core
2014-11-12T07:53:00 < englishman> hey speaking of actual debuggers
2014-11-12T07:53:05 < englishman> this flash flag shit
2014-11-12T07:53:13 < englishman> the flags arent actually set
2014-11-12T07:53:14 < dongs> its hardware (orwahtever), not done by swapping a breakpoint instruction into the code
2014-11-12T07:53:22 < englishman> cuz theyre just interrupt flags and you have to enable them
2014-11-12T07:53:40 < englishman> but whenever im having trouble, the two reserved bits in FLASH_SR go high
2014-11-12T07:53:40 < doelie> dongs: i understand the basic idea.
2014-11-12T07:53:52 < englishman> and writing clear_flags makes them go low and makes the problem go away
2014-11-12T07:54:16 < doelie> i just wonder if it's possible like on i386 to set hw breakpoint that changes execution to an exception handler.
2014-11-12T07:54:39 < dongs> doelie: so point is, even if you did manage to have register access to some FPB comparator to configure hardware breakpoint address, once you DID hit it, you'd be at a stopped core. the end.
2014-11-12T07:55:02 < doelie> so there's no way to not stop the core but to jump to handler instead?

2014-11-12T07:57:41 < doelie> yep pretty much what i got here
2014-11-12T07:57:58 < doelie> just wondered if there's a way to get it to trap without modifying flash or running from ram.
2014-11-12T07:58:04 < dongs> doelie: bonus points, figure out how to do this to a ROP-locked stm32
2014-11-12T07:58:28 < dongs> (stick stub in ram, ???, profit!)? maybe.
2014-11-12T07:58:59 < doelie> 20kb RAM<
2014-11-12T07:59:02 < doelie> :)
2014-11-12T07:59:15 < dongs> thats more than enough for cdcacm
2014-11-12T07:59:32 < doelie> stub isn't the problem.  it's the code that's being debugged which is a bit bigger.
2014-11-12T07:59:39 < dongs> st sample bootloader fits in 12k wiht -O0 , im sure if you did it right itwouldnt take more than 4k
2014-11-12T07:59:52 < doelie> stub is 0x2400 bytes
2014-11-12T08:00:47 < doelie> hey but just putting certain routines in ram might work.  those that need the breakpoints.
2014-11-12T08:01:24 < doelie> so what is ROP?
2014-11-12T08:01:46 < dongs> read out protection
2014-11-12T08:03:26 < doelie> so did you get around the rop?
2014-11-12T08:11:31 < dongs> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0337e/CEGHJDCF.html this might be relevant but its quickly becoming over my head
2014-11-12T08:11:36 < dongs> zyp might know better.
2014-11-12T08:11:48 < dongs> i dont think vector catchign is waht you want tho
2014-11-12T08:12:48 < dongs> i think tis rectangular but no idea
2014-11-12T08:12:56 < dongs>  just look at datasheet for 2011v3 lga or hwatever

2014-11-12T13:41:57 < jadew> since they happen after the stop bits
2014-11-12T13:42:14 < jadew> so any number of guard bits would be seen as an idling line (unless NACK is sent)
2014-11-12T13:43:27 < jadew> if you're getting framing errors, you either: 1) don't have the correct number of bits set. 2) You have the wrong baudrate. 3) You didn't enable parity check so it's expecting less bits
2014-11-12T13:44:17 < jadew> you said the LA is handling it properly, so it has to be a config issue with the scope

2014-11-12T16:50:27 < kakeman> it has 44 on backside
2014-11-12T16:50:39 < kakeman> cost like nuthin
2014-11-12T16:55:27 < jpa-> wouldn't it be less hassle just to make a proper pcb for the chip and all the other parts?
2014-11-12T16:58:49 < dongs> for the 2 or 3 times I needd a raw chip without a pcb i just used a wavesahre qfp48 socket...
2014-11-12T16:58:53 < dongs> and I didnt have to solder shit
2014-11-12T17:01:46 < kakeman> jpa-: for one time application
2014-11-12T17:01:49 < kakeman> I'm not sure
2014-11-12T17:03:21 < kakeman> it so easy just build it
2014-11-12T17:03:22 < jpa-> like it only has to work for 5 minutes?
2014-11-12T17:03:26 < jpa-> then maybe
2014-11-12T17:03:40 < jpa-> i rarely have stuff that is not worth doing well
2014-11-12T17:04:09 < jpa-> and dumping a >$10 chip on a breakout board seems stupid

2014-11-12T17:05:29 < kakeman> via rs232
2014-11-12T17:06:53 < kakeman> it's better to figure out first what kind of stuff you want to do with dds module
2014-11-12T17:07:20 < kakeman> before you put it into solid form
2014-11-12T17:07:50 < jpa-> i wonder how the physical module helps figuring that out..
2014-11-12T17:08:08 < jpa-> but yeah, many ways to proto
2014-11-12T17:09:06 < kakeman> I usually never ever use vero board

2014-11-12T19:59:54 < BrainDamage> looks like microsoft itself is jumping on the lunix bandwagon: http://news.microsoft.com/2014/11/12/microsoft-takes-net-open-source-and-cross-platform-adds-new-development-capabilities-with-visual-studio-2015-net-2015-and-visual-studio-online/
2014-11-12T20:00:34 < madist> does that mean anything ? how do you "open source" a language ?
2014-11-12T20:01:02 < karlp> means other compilers are allowed and will work
2014-11-12T20:01:18 < gxti> it lists exactpy what it includes
2014-11-12T20:01:21 < gxti> RTFA
2014-11-12T20:02:35 < karlp> this is what happens when you realize that windows phone apps aren't making people buy visual studio anymore :)
2014-11-12T20:02:50 < madist> meaningless. tomorrow microsoft can change .net in a way that's incompatible with linux use and you won't be able to do anything about it.
2014-11-12T20:03:18 < BrainDamage> I think you missed the part where the .net core, compiler, and framework will be open source
2014-11-12T20:04:25 < madist> when microsoft says "open source" I don't think they mean GPL.
2014-11-12T20:04:33 < jpa-> also, the part where the .net CLR and C# language are standardized
2014-11-12T20:04:37 < madist> They mean you can look at the source and use it, you can't change it.
2014-11-12T20:04:37 < qyx_> actually they may
2014-11-12T20:04:43 < qyx_> look at .net micro edition
2014-11-12T20:04:51 < jpa-> anyone can invent a new C# variant that is incompatible, but that doesn't mean the old one stops existing
2014-11-12T20:05:11 < madist> jpa-: that's the question I'm asking. does this give you the right to fork C# ?
2014-11-12T20:05:14 < qyx_> .net micro is apache2
2014-11-12T20:05:23 < jpa-> madist: you have had that right for years now, see mono
2014-11-12T20:05:46 < jpa-> microsoft has issued a binding (according to some lawyers) statements that it will not sue over c# forks
2014-11-12T20:06:17 < jpa-> my guess is that they are now open sourcing the asp.net because they have realized that 90% of web servers run linux
2014-11-12T20:06:45 < BrainDamage> that was my impression too, they are open sourcing the parts of .net necessary to run on a server
2014-11-12T20:07:14 < qyx_> thanksfuly in 2014
2014-11-12T20:07:16 < jpa-> note that they are not open sourcing anything that will make actual development work on linux easier, so people will still be buying visual studio
2014-11-12T20:07:18 < qyx_> better later than never
2014-11-12T20:07:36 < karlp> community edition only supports "non-enterprise" development :)
2014-11-12T20:08:40 < madist> the legalese is hard to understand. I see where they say they won't sue you for using C#. I don't see where they've said you can change the language.
2014-11-12T20:09:13 < jpa-> what is funny is that i was searching for something combining visual studio 2013 express for web + for desktop just today
2014-11-12T20:09:17 < jpa-> microsoft answered my calls ;)
2014-11-12T20:10:31 < madist> http://en.wikipedia.org/wiki/Microsoft_Open_Specification_Promise
2014-11-12T20:10:42 < madist> I don't think they've given anyone the freedom to fork C#
2014-11-12T20:10:55 < jpa-> eh, then what is mono doing?
2014-11-12T20:11:24 < madist> jpa-: mono is an implementation of microsoft's C#
2014-11-12T20:11:37 < jpa-> what makes it "not a fork"?

2014-11-12T20:12:07 < madist> extend the language.
2014-11-12T20:12:13 < jpa-> they have extended the language
2014-11-12T20:12:39 < jpa-> mono has SIMD, microsoft does not
2014-11-12T20:12:39 < madist> in what way ?
2014-11-12T20:12:58 < madist> what does SIMD mean in this context
2014-11-12T20:13:15 < jpa-> support for SSE2 and similar SIMD instruction sets, i.e. vectored code
2014-11-12T20:13:40 < madist> how is that a change to C# ?
2014-11-12T20:14:14 < jpa-> it requires new types in the CLR (which is part of microsoft .NET specs)
2014-11-12T20:14:23 < jpa-> i think maybe new instructions also
2014-11-12T20:19:04 < jpa-> apparently mono tries to avoid incompatible extensions, for the benefit of portability (and most reasonable extensions to C# can be implemented as libraries instead of in the compiler, due to the language's good introspection capabilities)
2014-11-12T20:20:01 < karlp> does mono have the asp.net stuff yet? there was a whole lot of the web framework stuff that just wasn't even on the drawing board for mono last I looked.
2014-11-12T20:20:11 < karlp> though I'm not looking at using it anyway....
2014-11-12T20:20:50 < jpa-> the list on the website lists "ASP.Net 4.0" as implemented, but not sure what that covers

2014-11-13T01:39:22 < englishman> yes
2014-11-13T01:39:29 < englishman> thing is
2014-11-13T01:39:36 < englishman> when i run/debug it asks for an executable
2014-11-13T01:39:45 < englishman> see at the end there, "use the default settings"
2014-11-13T01:39:52 < englishman> default run settings do not work.
2014-11-13T01:39:58 < englishman> (lunix'd)
2014-11-13T01:40:25 < englishman> i mean what is there for it to run anyway.
2014-11-13T01:40:47 < englishman> so im guessing it has to run some baremetal plugin, and in the baremetal sores there's run configuration stuff
2014-11-13T01:41:06 < englishman> but i dont see any of that, my only choice is to choose an executable to run

2014-11-13T06:28:00 < akaWolf> Steffanx: baremetal plugin didnt work with the generic project manager
2014-11-13T06:31:01 < akaWolf> but it's still possible to use Qt Creator with bare metal device using a generic project manager without any kind of bare metal plugin
2014-11-13T06:31:29 < akaWolf> it's what I'm doing at work
2014-11-13T06:32:08 < englishman> can you explain plz
2014-11-13T06:32:13 < dongs> whats hte big deal about qtcreator anyway
2014-11-13T06:32:16 < englishman> i think thats what im doing now
2014-11-13T06:32:17 < dongs> i used it once, the UI is so horrible
2014-11-13T06:32:20 < dongs> is it just a shitty freetard IDE?
2014-11-13T06:32:26 < englishman> i connect to openocd gdb
2014-11-13T06:32:37 < englishman> but there's no reset, no dynamic memory map
2014-11-13T06:33:03 < englishman> dongs: what do you recommend for lunix and onchip debugging gui
2014-11-13T06:33:33 < dongs> windows XP in virtualbox
2014-11-13T06:33:37 < akaWolf> englishman: yeah, but there is exist an gdb console, from which you can do anything what you are want
2014-11-13T06:33:55 < englishman> in qtcreator? or by running gdb
2014-11-13T06:34:10 < akaWolf> dongs: it's a preferable IDE at my taste
2014-11-13T06:34:16 < akaWolf> englishman: in Qt Creator
2014-11-13T06:34:20 < englishman> rly
2014-11-13T06:34:22 < akaWolf> yep
2014-11-13T06:34:45 < englishman> where?
2014-11-13T06:35:09 < dongs> even ST Visual Develop is better than QT cretinator
2014-11-13T06:35:33 < akaWolf> hmmm
2014-11-13T06:38:19 < englishman> and is the only way to see memory map to go to window->views->memory... and enter a location
2014-11-13T06:38:29 < englishman> cuz that's all that i see. and it's static
2014-11-13T06:39:02 < akaWolf> cant remember, where exactly. somewhere in the Menu, I havent at my home PC working copy of QtC
2014-11-13T06:39:41 < akaWolf> englishman: what are you want to see in memory?
2014-11-13T06:39:48 < englishman> periphs and stuff
2014-11-13T06:40:28 < englishman> last night when i was debugging i had to step -> open memory map at location -> step -> open memory map at location -> step -> open memory map at location -> step -> open memory map at location ->
2014-11-13T06:40:40 < akaWolf> QtC don't sharpened at any kind of MCU
2014-11-13T06:40:52 < englishman> that's fine
2014-11-13T06:41:02 < englishman> but i can see periphs at their memory map location
2014-11-13T06:41:42 < akaWolf> yeah, memory mapped periph
2014-11-13T06:41:52 < englishman> i should say address
2014-11-13T06:43:22 < akaWolf> you can try to type an expression like *((uint32_t *)address)
2014-11-13T06:44:09 < akaWolf> I think, it will be updated at every step
2014-11-13T06:45:17 < englishman> oooh

2014-11-13T07:02:12 < reportingsjr> this is driving me insane
2014-11-13T07:02:15 < PaulFertser_> englishman: I was told the only major limitation in bare metal plugin is that it works only with qt projects but not regular makefiles. I'll dig the logs and tell you more details later.
2014-11-13T07:02:48 < reportingsjr> so I am using the GCC example project provided in the project to try to make some demo code for the stm32 discovery VL board.
2014-11-13T07:02:54 < PaulFertser_> englishman: also there exists some standalone tool to show periph registers in a decoded way, I have to find it too.
2014-11-13T07:03:03 < reportingsjr> I modified the code to this: https://gist.github.com/reportingsjr/6fddc9955963935377b2
2014-11-13T07:03:12 < PaulFertser_> englishman: many people are using Eclipse for debugging, it seems it works fine.
2014-11-13T07:03:20 < reportingsjr> and I changed the define in the makefile to STM32F1 and the flash and ram size in the linker.
2014-11-13T07:03:23 < PaulFertser_> englishman: let's discuss it later today.
2014-11-13T07:03:33 < englishman> alright
2014-11-13T07:04:04 < englishman> i tried eclipse once, and ive spent way less time the last couple days getting qt working than i did on eclipse just to get it to compile.
2014-11-13T07:04:09 < reportingsjr> compiles fine and using arm gdb it uploads to the board fine, but nothing happens.. The LEDs on the board (labeled PC8 and PC9) should blink. Anyone know what is up?
2014-11-13T07:04:50 < reportingsjr> I was able to upload another blinky LED elf file to the board with arm gdb fine so I know that isn't the problem.
2014-11-13T07:04:55 < PaulFertser_> englishman: oh, how so? Last time I tried eclipse it was kinda easy with an existing Makefile, and probably it's makefile generator is okish too.
2014-11-13T07:06:51 < PaulFertser_> reportingsjr: I'd suggest an example project from libopencm3 instead, it has several for the vl board already.
2014-11-13T07:07:16 < reportingsjr> PaulFertser_: I didn't really want the whole overhead of libopencm3.
2014-11-13T07:07:18 < PaulFertser_> reportingsjr: dealing with the deprecated st library (which was shitty and is no better now) requires more effort.
2014-11-13T07:07:29 < PaulFertser_> reportingsjr: what overhead does it bring and where?
2014-11-13T07:07:42 < PaulFertser_> It'd be interesting to learn.
2014-11-13T07:08:16 < reportingsjr> PaulFertser_: having to dig through 10 levels of headers to figure out what underlying stuff is going on among other things.
2014-11-13T07:08:17 < PaulFertser_> reportingsjr: and one important suggestion regarding the shit-library. Always use the StructInit functions, can save you a lot of pain one day.
2014-11-13T07:09:21 < PaulFertser_> Ah, you mean overhead of checking the implementation. Well, it's your pov, and you're probably right. Albeit code comprehension tools help a lot with that making it a non-issue.
2014-11-13T07:10:10 < PaulFertser_> englishman: and if anything that's required for seamless IDE integration is missing from the OpenOCD side, I'd like to at least identify it.
2014-11-13T07:10:15 < reportingsjr> PaulFertser_: hmph, yeah, I just wanted to learn a decent amount about doing lower level embedded design so I can use platforms which don't have such nice libraries. :)
2014-11-13T07:10:26 < englishman> it seems to be fine, just connecting all the dots
2014-11-13T07:10:34 < reportingsjr> R2COM: for what particular thing?
2014-11-13T07:10:42 < englishman> I'll have a peek at eclipse tomorrow
2014-11-13T07:11:00 < PaulFertser_> reportingsjr: in your example you're initing pin8 but using pin8 and pin9.
2014-11-13T07:11:16 < reportingsjr> R2COM: oh, libopencm3 tends to have its source included 10 header files deep.
2014-11-13T07:11:34 < reportingsjr> PaulFertser_: good catch. However, I had just Pin 8 originailly and it still didn't work.
2014-11-13T07:11:36 < dongs> < reportingsjr> R2COM: oh, libopencm3 tends to have its source included 10 header files deep.
2014-11-13T07:11:40 < dongs> lol
2014-11-13T07:11:40 < reportingsjr> R2COM: what libraries do you recommend?
2014-11-13T07:11:53 < reportingsjr> R2COM: that is what I am trying to use right now..
2014-11-13T07:11:56 < reportingsjr> and it isn't working.
2014-11-13T07:12:02 < PaulFertser_> reportingsjr: is your code running, can you single-step through the main function to make sure it at least gets there?
2014-11-13T07:13:23 < dongs> R2COM: microsoft just released vs community
2014-11-13T07:13:28 < dongs> http://www.visualstudio.com/en-us/products/free-developer-offers-vs

2014-11-13T07:13:44 < dongs> so this is good now
2014-11-13T07:13:45 < dongs> yes
2014-11-13T07:14:06 < dongs> yes
2014-11-13T07:14:28 < reportingsjr> PaulFertser_: hmm, so I'm pretty new with all of this, including GDB. I loaded the code, did `break main` and then run. It doesn't seem to hit main, but the communication LED on the dev board is blinking away.
2014-11-13T07:14:35 < dongs> Q: How does Visual Studio Community 2013 compare to other Visual Studio editions?
2014-11-13T07:14:38 < dongs>  A: Visual Studio Community 2013 includes all the great functionality of Visual Studio Professional 2013, designed and optimized for individual developers, students, open source contributors, and small teams.
2014-11-13T07:14:52 < dongs> so its basically the only useful version of vs ( pro ) now free.
2014-11-13T07:14:55 < dongs> sounds like a win to me
2014-11-13T07:15:26 < dongs> no, theres no catch this time
2014-11-13T07:15:29 < dongs> cuz they want people to use thier shit.
2014-11-13T07:15:31 < PaulFertser_> My coworker had plenty of issues yesterday by using a project for stm32f103 as a basis for a new stm32f107 one. He didn't realise he needs plenty of stuff: change _MD define to _CL, use another startup, use matching .ld file, remove some stupid variable declaration from a header that was added by some other careless coworker etc. Would be so much easier if he just took a ready-made example from
2014-11-13T07:15:32 < dongs> its just free and works.
2014-11-13T07:15:37 < PaulFertser_> libopencm3-examples.
2014-11-13T07:16:21 < PaulFertser_> reportingsjr: ok, so if you're using openocd, do "mon reset halt" and then single step (instruction-wise) all the startup...
2014-11-13T07:16:36 < PaulFertser_> reportingsjr: make sure your stack point is correct etc.
2014-11-13T07:17:15 < reportingsjr> hmm, I'm not using openocd, but I can try it I suppose.
2014-11-13T07:18:03 < PaulFertser_> reportingsjr: if you're new to cortex-m, it's really better to start with something that already works on your specific device.
2014-11-13T07:18:52 < reportingsjr> PaulFertser_: well, I have successfully flashed this device with a blink elf file with gdb. I just didn't compile said elf. It was someone else's :P
2014-11-13T07:19:35 < PaulFertser_> reportingsjr: flashing is trivial, duh. Well, one needs to add a usb_storage quirk to tell the kernel to ignore the shitty debugger but that's about it.
2014-11-13T07:20:57 < reportingsjr> hmm
2014-11-13T07:21:36 < reportingsjr> PaulFertser_: one thing I noticed is that gdb says the start point is 0x8000320 and when I set the breakpoint for main() it set it at 0x80002c8.
2014-11-13T07:21:55 < PaulFertser_> reportingsjr: main is not your reset vector, that's normal.
2014-11-13T07:22:01 < reportingsjr> oh, ok

2014-11-13T07:23:18 < reportingsjr> when I killed the program here is what it was stopped at: x08000364 in WWDG_IRQHandler (). It is stopped at that point every time.
2014-11-13T07:23:34 < PaulFertser_> It's likely hardfault.
2014-11-13T07:24:04 < reportingsjr> what would be causing that?
2014-11-13T07:24:36 < PaulFertser_> Unless you're familiar with assembly-level debugging I wouldn't recommend messing with it... Well, for my coworker it was a wrong stack pointer because he carelessly edited the ld file.
2014-11-13T07:24:46 < PaulFertser_> But it can be anything else in your case, who knows.
2014-11-13T07:25:15 < reportingsjr> the only editing I did in the ld file was chaning the flash and ram size to match this dev board
2014-11-13T07:45:24 < reportingsjr> PaulFertser_: no other hints? :)

CW operation with Morse code is great for narrow-bandwidth low-speed communication over long distances. To take advantage of this, [Konstantinos] developed a program that takes binary or text files, compresses them, and translates them to a series of letters and numbers that can be represented with Mors

2014-11-13T12:24:47 < karlp> how are these 5m strings of 3528 leds wired normally? a friend has a string that's meant to be "12V" but it's not working, nor is the one he was sent as a replacement, and he claims it's 60 leds in series from looking through the silicon.

2014-11-13T17:57:32 < ReggieUK> hi all
2014-11-13T17:58:05 < ReggieUK> does anyone know much about usb host on the stm32F4-disco boards?
2014-11-13T17:59:49 < ReggieUK> got a synth firmware that someone has made, it takes midi input via a usb midi device (keyboard atm) connected to the micro-usb socket
2014-11-13T18:00:38 < ReggieUK> the firmware has issues recognising usb devices (basically, it doesn't really, you have to poke the right numbers into the code and compile, test, hope it works)
2014-11-13T18:01:31 < ReggieUK> so I'm hoping there might be some resources around that would give me pointers on how to deal with it correctly.
2014-11-13T18:02:28 < ReggieUK> It also appears to have power issues with the setup connected to a PC (keyboard acts up, eventually it gets into a reset loop)
2014-11-13T18:03:30 < ReggieUK> moved it to a usb wall power adapter (apple charger) and it's rock solid
2014-11-13T18:05:42 < zyp> wonder if that is related to any of emeb's stuff, he does synth stuff
2014-11-13T18:06:00 < ReggieUK> https://github.com/MrBlueXav/Dekrispator
2014-11-13T18:06:39 < zyp> ok, so it's not
2014-11-13T18:06:59 < zyp> where's the numbers you're talking about?
2014-11-13T18:07:34 < ReggieUK> https://github.com/MrBlueXav/Dekrispator/blob/master/USB/usbh_conf.h#L48
2014-11-13T18:07:37 < ReggieUK> that's one of them
2014-11-13T18:08:00 < ReggieUK> https://github.com/MrBlueXav/Dekrispator/blob/master/USB/MIDIstream_class/usbh_midi_core.c#L91
2014-11-13T18:08:02 < zyp> how so?
2014-11-13T18:08:53 < ReggieUK> and the rest are related to the arrays used in that function
2014-11-13T18:09:02 < ReggieUK> they're hardcoded
2014-11-13T18:09:29 < ReggieUK> and it's using 0x80 as the hardcoded endpoint to look for data on
2014-11-13T18:09:36 < zyp> no, it doesn't
2014-11-13T18:09:41 < ReggieUK> oh?
2014-11-13T18:10:01 < zyp> it's masking on the 0x80-bit which indicates whether it's an in or out endpoint
2014-11-13T18:10:30 < zyp> line 102 checks «is the first endpoint the in-endpoint?»
2014-11-13T18:11:27 < zyp> the only hardcoded assumption here is that your device only have one interface with only two endpoints

2014-11-13T18:13:22 < ReggieUK> aye, midi itself is simple too, I can cope with that
2014-11-13T18:13:37 < zyp> eh, you can't change the mask from 0x80 to 0x81, that would break everythin
2014-11-13T18:13:48 < ReggieUK> but not knowing usb at all.... has me guessing that changing a mask will fix things
2014-11-13T18:13:58 < ReggieUK> that's what makes it interesting
2014-11-13T18:14:04 < ReggieUK> I should've broken the firmware, yet it works
2014-11-13T18:14:04 < zyp> 0x01 will match 0x81, and suddenly your code believes your out endpoint is the in endpoint
2014-11-13T18:14:26 < zyp> do you have the descriptors from your midi device?

2014-11-13T18:40:59 < zyp> it has an audio control interface in front of the midi interface, and your midi code only supports one interface and goes looking for the endpoints in the first
2014-11-13T18:41:51 < ReggieUK> yes, that's where we have to change the hardcoded values (that's not my code but it's the original code I'm working from, it's about 6 changes to set the num interfaces and make it look at the right one)
2014-11-13T18:42:17 < zyp> you'll want to up the number of interfaces, and add a loop around the outer if block with an index into the list of interfaces
2014-11-13T18:43:38 < ReggieUK> I'm looking at another midi device in usbview, it's got an in endpoint address of 0x82, I'm guessing that's significant too?
2014-11-13T18:43:50 < zyp> no
2014-11-13T18:44:01 < zyp> they can be whatever
2014-11-13T18:44:20 < ReggieUK> and the mask covers that I take it?

2014-11-13T18:53:49 < zyp> actually, audio control seems to be mandatory for usb midi devices
2014-11-13T18:53:58 < zyp> I just looked up the spec
2014-11-13T18:55:18 < zyp> «The AudioControl interface describes the device structure (audio function topology) and is used to manipulate the Audio Controls. This device has no audio function incorporated. However, the AudioControl interface is mandatory and therefore both the standard AC interface descriptor and the class- specific AC interface descriptor must be present.»
2014-11-13T18:56:11 < ReggieUK> thank you, sorry if I seem lazy, I've kind of thrown myself into this with very little knowledge, I'm really surprised it works at all now you've said that :)
2014-11-13T18:57:47 < ReggieUK> the original firmware seems to rely on there being a single device on the unit, which if it's mandatory, it shouldn't be getting the midi information from the midi device descriptor's endpoint should it?
2014-11-13T18:58:07 < ReggieUK> or is the code just 'lucky' and it's assuming that midi from anywhere is ok to use?

2014-11-13T18:59:09 < ReggieUK> otherwise I don't get how the original firmware writer's midi works at all if it's only capable of seeing 1 device which technically does nothing

2014-11-13T23:38:15 < reportingsjr> Does anyone know of a decent, basic demo I can build off of for the discovery vl board using a gcc toolchain?
2014-11-13T23:38:48 < reportingsjr> I tried using the TNT example, but after modifying it to work for the discovery board (just changed the pins that get turned on and the flash and ram size) that didn't work.
2014-11-13T23:41:30 < Steffanx> libopencm3 has examples, but not sure if you consider them basic.
2014-11-13T23:41:47 < Steffanx> and it doesnt use the st peripheral lib ofcourse
2014-11-13T23:42:14 < reportingsjr> I kinda wanted to just use the st peripheral library. Part of the reason for this is so I can try to get a little bit of a better understanding of the hardware.
2014-11-13T23:42:48 < englishman> Doesn't st have a ton of example projects, with gcc startups etc
2014-11-13T23:43:00 < reportingsjr> englishman: if so I haven't been able to find them.
2014-11-13T23:43:55 < reportingsjr> I can't even find the st peripheral library on their own site.
2014-11-13T23:44:09 < reportingsjr> Every link to it I have found is dead and searching their site doesn't work.

2014-11-14T01:29:14 < scummos> works on the same hub with a normal, shielded cable? did you try in full-speed mode, if possible?
2014-11-14T01:29:31 < Laurenceb__> yes
2014-11-14T01:29:35 < Laurenceb__> it works fine
2014-11-14T01:29:43 < Laurenceb__> wit a normal cable
2014-11-14T01:30:11 < scummos> maybe you can force the hub to full-speed and check if it works with your cable
2014-11-14T01:31:53 < Laurenceb__> yeah thats what im wondering
2014-11-14T01:31:59 < Laurenceb__> doesnt seem so simple in linux
2014-11-14T01:32:11 < Laurenceb__> its weird that the camera seems to work

2014-11-14T03:20:22 < dongs>  The slots are put in manually, with a pad on top and bottom and a milling detail in between. Unfortunately, there.s nothing in that to tell Eagle not to put a copper pour in the middle layers. So I had plated slots going straight through the two middle planes: Ground and 3.3v.

2014-11-14T03:20:32 < dongs>  Eagle.s built in board check didn.t catch it because as far as the CAD is concerned, they aren.t connected.

2014-11-14T03:46:35 < reportingsjr> Not sure how that happened in eagle, but it did.
2014-11-14T03:49:24 < dongs> i thought you were trying to come up wiht excuse for why it was ok for eagle to fail but seems you just made it worse
2014-11-14T03:49:45 < reportingsjr> its because eagle sucks
2014-11-14T03:49:54 < dongs> combine that with the fact that the software is basicalyl unusable for like common simple tasks and i have no fucking idea why people still bother using it

2014-11-14T03:51:48 < dongs> the  same "job" (presuming your typical make:r trash) could be done like 5x faster in diptrace for example.
2014-11-14T03:52:20 < dongs> the usual excuse of "but but eagle includes thousands of amazing wrongly drawn components by aidsfruit" doesn't work here because its trivial to make new parts/footprints in diptrace
2014-11-14T03:52:36 < dongs> eagle has this shit b eacuse its component editor fuckign sucks
2014-11-14T03:52:45 < dongs> and you couldnt evne extract parts used in a design until some recent version
2014-11-14T03:52:55 < dongs> like, really????

2014-11-14T03:53:55 < qyx_> it depends
2014-11-14T03:54:35 < qyx_> i tried diptrace and uninstalled, its ui vas even worse than eagle's
2014-11-14T03:54:40 < qyx_> *was
2014-11-14T03:54:41 < qyx_> meh
2014-11-14T03:54:59 < dongs> wut
2014-11-14T03:55:04 < dongs> which part did you find "worse"
2014-11-14T03:56:14 < qyx_> i didnt like the component selector, but meybe it just needs to get used to
2014-11-14T03:56:39 < qyx_> and, seriously, delphi
2014-11-14T03:56:43 < dongs> they did change it to something dum in latest version but i already was close to dumping it at that point so i didnt rage much
2014-11-14T03:56:49 < dongs> well, altium is delphi too :p
2014-11-14T03:57:12 < zyp> wat
2014-11-14T03:57:14 < dongs> common assert errors in DX3DScene.pas
2014-11-14T03:57:18 < dongs> zyp, wat wat.
2014-11-14T03:57:35 < zyp> delphi wat
2014-11-14T03:57:38 < qyx_> asserts in release software
2014-11-14T03:57:41 < dongs> yaeh dead srs
2014-11-14T03:57:42 < zyp> didn't know that was still a thing
2014-11-14T03:57:48 < dongs> altidong is delphi.
2014-11-14T03:58:11 < dongs> as you can see only real pro EDA is written in delphi
2014-11-14T03:58:14 < dongs> dicktrace, altium
2014-11-14T03:58:46 < dongs> eagle is crossplatform shit right>?
2014-11-14T03:58:50 < dongs> so its probly C with some hacks
2014-11-14T03:58:55 < dongs> what do tehy use for cross platform
2014-11-14T03:58:56 < dongs> QT?
2014-11-14T03:59:00 < zyp> I believe so
2014-11-14T03:59:19 < qyx_> c++ and qt
2014-11-14T03:59:29 < dongs> wow eagle statically links in qt
2014-11-14T03:59:33 < dongs> amazing
2014-11-14T03:59:39 < qyx_> truly amazing
2014-11-14T03:59:46 < qyx_> and 32bit
2014-11-14T03:59:48 < qyx_> like in 2000
2014-11-14T03:59:49 < dongs> typically opesores trash will have 3000 libs strewn all over the place
2014-11-14T03:59:58 < qyx_> wat
2014-11-14T04:00:10 < qyx_> thats the purpose of shared lubs
2014-11-14T04:00:38 < dongs> shared libs assumes more than one person uses them
2014-11-14T04:00:52 < qyx_> it links its 32bit qt shit and then rest of the things don't work
2014-11-14T04:01:01 < dongs> wehn you have libfuckoff.so.0.0.1 thats used by gaydumbopensoresshit0.001beta, theres no fucking reason to dynamic link
2014-11-14T04:01:11 < qyx_> like system theme renderers
2014-11-14T04:01:14 < qyx_> then it looks like meh
2014-11-14T04:01:21 < reportingsjr> dongs: diptrace isn't a pro EDA tool..
2014-11-14T04:01:24 < dongs> that sounds like a lunix problem
2014-11-14T04:01:29 < dongs> also > complaining about eagle looks
2014-11-14T04:01:40 < dongs> reportingsjr: its certainly more pro than eagle
2014-11-14T04:01:46 < qyx_> complaining about linking qt statically
2014-11-14T04:01:49 < reportingsjr> ehh, I would put them about the same level
2014-11-14T04:02:11 < qyx_> same thing with draftsight, skype, etc
2014-11-14T04:02:33 < qyx_> because they still in 2014 don't know how to use packaging systems
2014-11-14T04:02:36 < qyx_> and do it like in windows
2014-11-14T04:02:47 < qyx_> with tons of custom installer tools
2014-11-14T04:03:16 < dongs> > packaging systems
2014-11-14T04:03:29 < dongs> because you need to make a different package for a million lunix distros
2014-11-14T04:03:36 < dongs> maintaining that shit is fucking insane
2014-11-14T04:03:42 < qyx_> they are there to ressolve required dependencies
2014-11-14T04:03:46 < dongs> so its easier to write ONE custom installer that will hack shit into a million lunix distros
2014-11-14T04:03:55 < reportingsjr> I'm confused where linux came in to this
2014-11-14T04:03:56 < dongs> haha dude, do you even
2014-11-14T04:04:12 < reportingsjr> all of the tools you are talking about are pretty much windows only

2014-11-14T04:04:18 < qyx_> wut

2014-11-14T04:04:29 < reportingsjr> dongs: ahh, I forgot you were a troll
2014-11-14T04:04:35 < reportingsjr> you were over in hackvana as well
2014-11-14T04:04:43 < dongs> yes, exactly
2014-11-14T04:04:49 < reportingsjr> carry on
2014-11-14T04:04:57 < dongs> until i got trolled out of there by dickgirl love
2014-11-14T04:05:06 < reportingsjr> dongs: ever used any of the pro tools btw?
2014-11-14T04:05:13 < reportingsjr> altium, pads, orcad?
2014-11-14T04:05:29 < dongs> ive dicked around with altium, i currently use that for all my projects.
2014-11-14T04:05:36 < dongs> orcad felt like it was 1996 all over again
2014-11-14T04:05:39 < dongs> never tried pads.
2014-11-14T04:06:01 < reportingsjr> pads is probably the most powerful, but most esoteric
2014-11-14T04:06:12 < dongs> i generally agree with this article http://www.eetimes.com/author.asp?section_id=69&doc_id=1321332
2014-11-14T04:06:42 < dongs>  i did the jump to altium from diptrace because it started to get difficult to get stuff done quickly and efficiently with it, but I plan to stick with that for a while now.
2014-11-14T04:06:55 < dongs> that = altium

2014-11-14T04:37:49 < reportingsjr> however, it hits this line: _RCC_REG(clken) |= _RCC_BIT(clken); and after that gives me this: Cannot access memory at address 0xbeffa3dc

2014-11-14T09:13:55 < Claude> what are you doing there dongs ? hacking paytv smartcards?
2014-11-14T09:15:11 < dongs> nah just fixing firmware for a smartcard>i2c bridge because the fucks at work are too cheap to pay for TDA8024...
2014-11-14T09:15:19 < Claude> ah :)
2014-11-14T09:15:27 < dongs> (and SoC doesn't support smartcard uart anyway, so it'd be 2 chips after all, bla bla)
2014-11-14T09:15:47 < Claude> stm8 ? how are these compared to e.g. AVRs and so
2014-11-14T09:15:55 < dongs> absolutely amazing
2014-11-14T09:16:00 < dongs> proper debug unit, proper peripherals
2014-11-14T09:16:03 < Claude> cosmic compiler?
2014-11-14T09:16:06 < dongs> ya
2014-11-14T09:16:08 < dongs> ffree 32k shit
2014-11-14T09:16:15 < dongs> this chip is like 8k flash
2014-11-14T09:16:19 < dongs> so its perfectly fine for it
2014-11-14T09:16:32 < Claude> cool , well stm8 are quite cheap . cheaper than usual 8bit mcus
2014-11-14T09:16:44 < Claude> usual as in avr ;)
2014-11-14T09:16:49 < dongs> i think so, i forget wat we're paying for them but its like 20-25c or something for that S003
2014-11-14T09:16:55 < dongs> AVR would be more and doesn't have required peripherals.
2014-11-14T09:17:00 < Claude> yeah
2014-11-14T09:17:37 < dongs> I2C hardware on STM8 smeels a bit of the stuff on STM32 but actually works
2014-11-14T09:17:58 < dongs> there's the same EV1/2/3 stuff
2014-11-14T09:18:05 < dongs> but it doessnt bug out in interrupts
2014-11-14T09:18:27 < dongs> and doens't need specialcasing for byte before last, bla bla shit
2014-11-14T09:18:34 < Claude> yes i did some stuff with an stm32l151 , the datasheet of the stm8(l? lowpower) and the stm32l151 are 90% identical :)
2014-11-14T09:19:09 < dongs> anyway proper hardware debugger iswhat makes it awesome above any AVR trash
2014-11-14T09:19:19 < dongs> and pretty much instant flashing w/new firmware
2014-11-14T09:19:48 < Claude> indeed , atmel jtagice/dragon just stinks , especially with this avr 6.x ide
2014-11-14T09:20:08 < dongs> i used dragon once, gave it away
2014-11-14T09:20:12 < dongs> it was horrible
2014-11-14T09:20:29 < dongs> slow as shit

2014-11-14T09:27:25 < dongs> megawin-disco
2014-11-14T09:28:58 < dongs> also stm8 runs at 3V or 5V without speed degrade
2014-11-14T09:28:59 < dongs> like avr
2014-11-14T09:29:16 < dongs> also i tihnk the core is same between A and S, so you can just stick 24mhz xtal on the S version and it runs at 24
2014-11-14T09:29:24 < dongs> (while only spec'd for 16

2014-11-14T10:14:49 < dymk> Does anyone have an opinion on the CrossWorks IDE for STM32F4 development?
2014-11-14T10:15:13 < dymk> I normally hate IDEs, but I need something to get the newer team members up and running with the uCs
2014-11-14T10:18:20 < englishman> does it need to be "free" "awful" "shit"
2014-11-14T10:18:55 < englishman> ohhh school right
2014-11-14T10:19:04 < tkoskine> CrossWorks for ARM is nice. I have been using it for 6 months or so now.
2014-11-14T10:19:04 < englishman> keil is free for <32k
2014-11-14T10:19:06 < englishman> and actually works
2014-11-14T10:19:39 < tkoskine> I find CrossWorks' UI to be much better than IAR's or Keil's.
2014-11-14T10:20:15 < tkoskine> However, CrossWorks uses gcc (or clang) as compiler. That might be good or bad, depending on your needs.
2014-11-14T10:20:24 < englishman> i think Qt's is the best, its so pretty, unfortunately useless
2014-11-14T10:21:37 < dymk> Just needs to work on linux is all
2014-11-14T10:21:51 < dymk> I guess could go the route of using eclipse or something of that ilk
2014-11-14T10:21:55  * dymk shudders
2014-11-14T10:22:30 < dymk> so far, crossworks is kinda being magically great compared to setting up a custom build GCC environment/uploader last week
2014-11-14T10:22:39 < dymk> the debugger is really nice
2014-11-14T10:24:10 < dymk> and look at that, they have a debug_printf
2014-11-14T10:25:01 < englishman> Aka avr emulator
2014-11-14T10:26:26 < dymk> if the alternative is having two usb cords just to be able to both program the thing and use printf, then avr emulator it is
2014-11-14T10:26:54 < englishman> I think you are missing the point
2014-11-14T10:27:13 < englishman> Printf debugging, on a chip with onchip debugger
2014-11-14T10:27:20 < englishman> The Arduino Way
2014-11-14T10:27:47 < dymk> I need to push the value of an ADC to the computer as fast as possible
2014-11-14T10:27:59 < dymk> just print a line with the value over and over
2014-11-14T10:28:46 < dymk> debugger means I have to have GDB do something each time the value changes, with a bunch of other errata i don't care about
2014-11-14T10:30:07 < dymk> so I'm not using printf for debugging, but it just so happens, one has to use the debug printf to make the OCD spit out stuff like it's a terminal
2014-11-14T10:31:32 < dymk> maybe there's a way to set up uart/usart comms over the same connection the OCD is using, but i'm not aware of it

2014-11-14T15:11:57 < Laurenceb> heh
2014-11-14T15:11:59 < scummos> 480 MHz through ribbon-cable does sound a bit adventurous
2014-11-14T15:12:11 < scummos> do you have each second wire ground or so?
2014-11-14T15:12:17 < Laurenceb> theoretically it should be close to impedance matched
2014-11-14T15:12:19 < Laurenceb> yeah
2014-11-14T15:12:30 < Laurenceb> gnd, D+,D-, V+
2014-11-14T15:12:59 < karlp> that's not "yeah" that's "not at all"
2014-11-14T15:13:14 < scummos> I'd try with a shorter piece of cable, if it's because of electrical problems that should solve it
2014-11-14T15:13:34 < karlp> 10cm is short enough, it's not going to get better with shorter
2014-11-14T15:13:38 < Laurenceb> karlp: gnd,D=, gnd, D-, gnd doesnt have the right impedance
2014-11-14T15:13:47 < scummos> karlp: ... yes, I noticed my question doesn't make a lot of sense though, Laurenceb's configuration sounds like the best choice
2014-11-14T15:14:16 < Laurenceb> yeah i calculated the impedance and its almost spot on
2014-11-14T15:14:42 < scummos> 10cm is like 1/4 wavelength at the involed frequencies, so I think it might matter
2014-11-14T15:14:46 < scummos> hmm :(
2014-11-14T15:14:55 < scummos> tried a different cable? :D
2014-11-14T15:15:21 < Laurenceb> ive tried an off the shelf cable
2014-11-14T15:15:23 < Laurenceb> works fine
2014-11-14T15:16:48 < Laurenceb> maybe i could scope it
2014-11-14T15:17:09 < scummos> do you have a 2 GHz scope? ;P
2014-11-14T15:17:16 < Laurenceb> yes
2014-11-14T15:17:55 < scummos> oh, cool ... then that sounds like a good idea to me :)

2014-11-14T15:21:49 < madist> cheap ass chinese usb cables are just a bunch of wires - if that can work over a meter long, then why would ribbon cable not work ?
2014-11-14T15:21:55 < BrainDamage> considering most of your field would be in the air surrounding your strip, immediately above and below, I don't see that kludge working that well any metallic object including traces and enclosures will fuck up yor impedance badly
2014-11-14T15:22:03 < BrainDamage> @ failrenceb
2014-11-14T15:22:29 < madist> BrainDamage: so the sheilding around the wire bundle is what makes a usb cable work ?
2014-11-14T15:22:58 < Laurenceb> ok ill try it with the cable away from anything metallic
2014-11-14T15:23:48 < BrainDamage> partially, it doesn't help either that usb isn't a differential only signal
2014-11-14T15:23:56 < BrainDamage> there are common mode signals part of the protocol
2014-11-14T15:24:03 < BrainDamage> and you want matched impedance for those too
2014-11-14T15:24:06 < madist> but that's almost DC no ?
2014-11-14T15:24:30 < BrainDamage> iirc there's some negotiation signals too

2014-11-14T16:13:55 < Kliment> Anyone familiar with the boot settings of the f0 series?
2014-11-14T16:14:04 < dongs> sure
2014-11-14T16:14:07 < dongs> define "boot settings"
2014-11-14T16:14:12 < dongs> you mean boot0/1?
2014-11-14T16:14:45 < Kliment> Yes. When I tie boot0 to vcc I can load a program and run it via gdb
2014-11-14T16:14:58 < Kliment> When I tie it to ground, I can load a program but it won't run
2014-11-14T16:15:25 < dongs> loading and running are two separate things
2014-11-14T16:15:38 < dongs> 'run from flash on reset' is boot1 to ground, boot0 to ground.
2014-11-14T16:15:48 < Kliment> boot1 is not a pin
2014-11-14T16:15:49 < dongs> if  boot0 is at vcc, it will run from bootloader.
2014-11-14T16:15:57 < dongs> oh, option bytes?
2014-11-14T16:16:04 < dongs> should be same tho
2014-11-14T16:16:32 < Kliment> Okay, I can't get my code to run from flash though
2014-11-14T16:16:59 < dongs> like i said, 'loading' to flash and 'executing' it are separate things.
2014-11-14T16:17:05 < dongs> you reset it after load?
2014-11-14T16:17:07 < Kliment> Yes
2014-11-14T16:17:14 < Kliment> With debugger still attached
2014-11-14T16:17:34 < Kliment> And it tells me it's stuck in blocking_handler
2014-11-14T16:17:35 < dongs> i didnt dick with f0 but im gonna  take a wild guess that default optionbyte for boot1 is execute from flash one
2014-11-14T16:18:03 < Kliment> Yeah, and according to the manual the boot1 bit gets ignored if boot0 is set to "boot from flash"
2014-11-14T16:18:12 < dongs> right, that would make sense
2014-11-14T16:18:20 < dongs> so boot0 should be tied low
2014-11-14T16:18:22 < dongs> and that would be flash.
2014-11-14T16:18:40 < Kliment> Yep. But I tried that and the program would not run at all
2014-11-14T16:18:58 < dongs> high is bootloader. at least thats the case on F1, F2, F3, F4, so i don't see why it would be different on F0.
2014-11-14T16:19:21 < Kliment> Yeah, in bootloader mode I can load and run code via gdb
2014-11-14T16:19:21 < emeryth> I'm working on f0 right now, it's just like f1
2014-11-14T16:19:37 < emeryth> no problems here with gdb
2014-11-14T16:19:47 < Kliment> emeryth: the gpio is totally different, f0 is closer to f2 in that sense, but other than that yeah
2014-11-14T16:21:33 < Kliment> So if I tie boot0 high I can load and run code from gdb, but with the debugger disconnected it won't run at all
2014-11-14T16:22:43 < emeryth> you're doing something wrong
2014-11-14T16:22:47 < Kliment> If I tie boot0 low it claims to write code to flash but nothing happens when I try to run it. If I break it via gdb it tells me it's in blocking_handler
2014-11-14T16:23:02 < Kliment> emeryth: Evidently, the question is what.
2014-11-14T16:23:09 < dongs> are you sure you didnt misunderstand your boot0 high/low shit
2014-11-14T16:23:28 < dongs> cuz it sounds like its working opposite of what it should be
2014-11-14T16:23:51 < Kliment> dongs: No, if it's tied high it enters the bootloader on boot, rather than the code, as it should
2014-11-14T16:24:10 < Kliment> dongs: The only case that is not working as it should is with it tied low
2014-11-14T16:24:37 < dongs> and your "code" isnt fucked up?
2014-11-14T16:24:49 < Laurenceb> hmm.. maybe im not driving this cable correctly
2014-11-14T16:25:01 < Laurenceb> should shield be connected to GND on a normal cable?
2014-11-14T16:25:05 < Kliment> dongs: Let me reduce it to a simple pin toggle and try again
2014-11-14T16:27:42 < Kliment> dongs: Nope, same thing
2014-11-14T16:28:04 < Kliment> dongs: Exact same code works with boot0 tied high
2014-11-14T16:28:10 < dongs> weird.
2014-11-14T16:28:26 < dongs> got uart? erase chip, flash via uart bootloader, reset.
2014-11-14T16:29:12 < dongs> wait
2014-11-14T16:29:18 < dongs> are you sure you are loading the shit to flash
2014-11-14T16:29:19 < dongs> and not ram
2014-11-14T16:29:22 < dongs> heh
2014-11-14T16:30:12 < Kliment> It says "Flash written and verified"
2014-11-14T16:33:56 < Kliment> So, the blocking handler appears to be part of libopencm3 and gets called in case of hard fault

Also I don't believe that the compiler can discard all those symbols, since only the linker can know that they're unreferenced. What am I doing wrong?

2014-11-14T23:10:50 < zyp> building your file, I get four bytes of .data and four bytes of .rodata, i.e. your two variables
2014-11-14T23:10:55 < zyp> that's without -fdata-sections
2014-11-14T23:11:10 < zyp> -fdata-sections will put them into named sections instead
2014-11-14T23:11:40 < zyp> i.e. .data.global_mutable_value and .rodata._ZL21global_constant_value

2014-11-14T23:12:10 < zyp> the constructor is not emitted, since inlining it in the class definition like that makes the definition static
2014-11-14T23:13:05 < decimad2> Okay, the .data.global_mutable_value I have too, I overlooked it between the debug sections (I ignore them for now, too advanced).
2014-11-14T23:13:30 < decimad2> but shouldn't the constructor be found in .text or a named section?
2014-11-14T23:13:43 < zyp> consider this; the function can't be called without being declared in a different translation unit, and since it's inlined in the class definition itself, including the declaration also includes the definition, and thereby you don't need extern linkage
2014-11-14T23:13:45 < decimad2> ahh, I read omitted instead of emitted, sorry
2014-11-14T23:14:27 < zyp> if you define the constructor outside of the class, you'll get it emitted in .text (or a named subsection)
2014-11-14T23:14:35 < zyp> i.e. .text._ZN12sample_classC2Ev
2014-11-14T23:14:50 < decimad2> Oh, so if I had done the normal declaration definition separation instead of being quick the compiler hadn't outsmarted me! :D
2014-11-14T23:15:01 < zyp> yes
2014-11-14T23:16:22 < decimad2> So these things make sense, great, thank you! Now I only gotta find the .rodata for the constant global... it's not there...

2014-11-14T23:31:04 < decimad2> you're right, great! so optimize for debug still has some quirks. But how can he? How would other files get the constant value?
2014-11-14T23:31:36 < zyp> no, I didn't try with -Og

2014-11-14T23:52:36 < Laurenceb__> coolio
2014-11-14T23:53:17 < decimad2> but internal linkage only means that the symbols are internal to the cu... how would "extern const int GLOBAL_CONST_VAR;" and in one source file "const int GLOBAL_CONST_VAR = 0xFF;" work then Oo
2014-11-14T23:53:45 < decimad2> it's marked as working in the respective stackoverflow "http://stackoverflow.com/questions/2268749/defining-global-constant-in-c"
2014-11-14T23:54:21 < zyp> decimad2, just include the full thing in all files
2014-11-14T23:54:46 < zyp> most of the time it will be inlined and folded
2014-11-14T23:55:01 < zyp> and even if it needs to be emitted, I think it will be emitted as a common symbol
2014-11-14T23:55:07 < decimad2> Yes, that's what I would do, but technically the extern-thingy must work to, doesn't it? Do I have to have the extern-declaration in the cu that defines the object?
2014-11-14T23:55:11 < zyp> which means that duplicates will be discarded
2014-11-14T23:55:26 < decimad2> let's see
2014-11-14T23:55:29 < zyp> in other words, don't use extern for const globals
2014-11-14T23:56:32 < decimad2> okay, having the extern declaration there brings it through the optimizer ;)
2014-11-14T23:57:18 < decimad2> I wasn't aware that the defining cu also needs the extern... and no, I will not use extern constants, I just needed to understand this.

2014-11-15T00:07:14 < [7]> are there any special weirdnesses to watch out for on F107 regarding ethernet?
2014-11-15T00:07:38 < [7]> I'm trying to port my code which works on f205 to f107, and can't seem to get it to work there
2014-11-15T00:07:58 < [7]> I can talk to the MAC core, and it appears to be sending packets, but they never end up on the ethernet wire
2014-11-15T00:08:17 < [7]> and I never receive any packets, not even any broadcast junk
2014-11-15T00:08:58 < [7]> I'm using the same ethernet driver that worked for me on f205, and adapted RCC, GPIO, AFIO etc. to work on the f107
2014-11-15T00:09:17 < [7]> I'm also using the same PHY hardware so I can rule that out
2014-11-15T00:09:25 < [7]> are there any common pitfalls in that area?
2014-11-15T00:09:40 < scrts> non working DMA?
2014-11-15T00:09:56 < [7]> the DMA engine seems to be picking up and processing my TX requests
2014-11-15T00:10:08 < [7]> it sets the "own" bit back to zero
2014-11-15T00:11:11 < [7]> I also hope to have the pin config right, although that F1 series GPIO controller is rather weird if you're used to f2/f4 series
2014-11-15T00:12:13 < [7]> I've set PA1 to INPUT FLOATING (RMII_REF_CLK), PA2 to OUT 2MHZ PUSHPULL (MDIO), PA7 to INPUT FLOATING (RMII_CRS_DV)

2014-11-15T00:13:49 < [7]> at least that's what I think what my code does ;)
2014-11-15T00:18:09 < scrts> did you check with the scope whats happening on the lines?

2014-11-15T01:18:45 < [7]> scrts: RMII clock is sourced externally and seems to be working (if I remove it, resetting the MAC locks up)
2014-11-15T01:19:00 < [7]> MDIO also works, I can interrogate the PHY about the link properties successfully
2014-11-15T01:19:11 < [7]> there are just no packets getting through
2014-11-15T01:19:47 < scrts> rx path works?
2014-11-15T01:21:14 < kakeman> karlp: something basic no special needs
2014-11-15T01:21:32 < [7]> scrts: no, I'm never getting IRQs and the RX DMA state is "waiting for packets"
2014-11-15T01:21:51 < [7]> so from the MCU's point of view it seems as if the TX/RX lines to the phy would be messed up
2014-11-15T01:22:00 < scrts> oh...
2014-11-15T01:22:01 < [7]> which makes me suspect a GPIO/AFIO config problem
2014-11-15T01:22:03 < scrts> interesting
2014-11-15T01:22:09 < [7]> and I'm not really familiar with the GPIO controller of F1
2014-11-15T01:22:30 < karlp> that's because it is teh suck ;)

2014-11-15T01:43:49 < ds2> would be nice if someone had one with an integrated filterr
2014-11-15T01:46:05 < [7]> scrts: I just hooked up a scope, and it confirms what I was suspecting
2014-11-15T01:46:19 < [7]> CRS_DV shows packets being received by the PHY, which the MAC never seems to see
2014-11-15T01:46:29 < [7]> TX_EN is never asserted, despite the MAC claiming to have sent packets
2014-11-15T01:48:32 < [7]> so what is the correct pin config for this thing? and which other things might be interfering?
2014-11-15T01:53:35 < [7]> my GPIO config is PORTA LOW 0x11111a11 HIGH 0x21111111 PORTB LOW 0x11111111 HIGH 0x11eee111 PORTC LOW 0x111188a1 HIGH 0x31111111
2014-11-15T01:53:43 < [7]> any obvious mistake?
2014-11-15T01:58:18 < [7]> hm, that almost looks as if CNF and MODE were swapped for some reason. let me check.
2014-11-15T02:08:22 < [7]> ok, looks like there was a bug indeed
2014-11-15T02:08:26 < [7]> but it still doesn't work
2014-11-15T02:08:33 < [7]> now the TX_EN line is always high...

2014-11-15T02:22:52 < dongs> AFIO_MAPR? isnt it
2014-11-15T02:23:04 < dongs> but on F1 its just a couple possibilities so
2014-11-15T02:23:07 < dongs> its not too complex

2014-11-15T02:25:14 < [7]> yeah, but there can be collisions the way it's handled on F1
2014-11-15T02:25:28 < [7]> e.g. a UART clashing with ethernet
2014-11-15T02:25:44 < dongs> yes
2014-11-15T02:25:56 < [7]> what decides who wins in such cases?
2014-11-15T02:26:10 < dongs> um, reference manual/datasheet is very clear about ti
2014-11-15T02:26:30 < dongs> the winner is the remap, afaik
2014-11-15T02:26:52 < [7]> in my particular case I'm looking at PB11
2014-11-15T02:26:56 < [7]> which is ethernet TX_EN
2014-11-15T02:27:21 < [7]> and which can also be accessed by TIM2 and USART3 IIUC
2014-11-15T02:27:40 < [7]> ethernet is always using it, and cannot be remapped to another pin
2014-11-15T02:28:01 < [7]> UART3 is using it in the default (no remap) config as well
2014-11-15T02:28:15 < [7]> does this mean that I have to remap UART3 in order to be able to use ethernet?
2014-11-15T02:28:28 < dongs> do you have uart3 on?
2014-11-15T02:28:33 < dongs> if not, then you dont need to care
2014-11-15T02:28:38 < dongs> if it doesnt have its clock on, it doesnt exist
2014-11-15T02:28:56 < [7]> in this case it's RX of that UART, so I guess it wouldn't matter anyway, but for e.h. PB12 it does
2014-11-15T02:29:16 < dongs> on F1 you can't disable just rx or just tx for a perioperal
2014-11-15T02:29:27 < dongs> wel, you sorta can, but only if y ou use it as gpio
2014-11-15T02:29:32 < [7]> well RX is an input so I guess it just won't care about a collision
2014-11-15T02:32:04 < [7]> gah
2014-11-15T02:32:19 < [7]> looks like some (pointlessly) enabled clocks were indeed the problem
2014-11-15T02:32:32 < [7]> man, that chip's I/O logic is all the way weird

2014-11-16T15:24:21 < talsit_roam> so, has anyone had much experience with streaming data to SD? as in, a continuous stream for hours?
2014-11-16T15:29:28 < PaulFertser> talsit_roam: I participated in a project that needed that, we used blackfin bf504 though, not stm32, but shouldn't matter. IIRC you have to assume that SD might occassionally need as much as probably 1 second to finish a write operation. And that some SDs can go bad (increasingly and measureably slower for both writes and reads), that's sometimes curable by writing 0s over the whole card.
2014-11-16T15:29:50 < talsit_roam> yeah, exactly
2014-11-16T15:30:02 < talsit_roam> they sometimes stall for over 500ms
2014-11-16T15:30:28 < talsit_roam> and my MCU only has enough buffer for ~200ms of data
2014-11-16T15:30:56 < talsit_roam> so usually ~500ms of data gets lost per 30 minutes or so
2014-11-16T15:31:04 < talsit_roam> which is not much, but still unacceptable
2014-11-16T15:31:10 < dongs> buffer moar.

2014-11-16T15:33:48 < talsit_roam> yeah... i know i need to buffer more, i'm just wondering what people usually use....
2014-11-16T15:34:21 < Thorn> what is the data rate?
2014-11-16T15:35:00 < talsit_roam> ~300kb/s
2014-11-16T15:36:54 < dongs> kilobytes?
2014-11-16T15:37:42 < talsit_roam> ~300000 bytes per second
2014-11-16T15:37:43 < PaulFertser> talsit_roam: have you tried zeroing out the card before operation? It might help as sort of a band-aid I guess.
2014-11-16T15:38:07 < PaulFertser> Not the whole card, just the partition.
2014-11-16T15:38:21 < talsit_roam> PaulFertser: yes, but still, all cards will stall at some point
2014-11-16T15:38:51 < PaulFertser> Blame stupid SD vendors that refuse to expose lowlevel interface to nand.

2014-11-17T00:54:36 < scrts> [7]: did you solve the gpio issue?
2014-11-17T00:54:50 < [7]> scrts: you mean that ethernet one?
2014-11-17T00:54:55 < scrts> yea
2014-11-17T00:55:19 < [7]> didn't quite figure out what it was, but shutting off some non-required clock gates fixed it
2014-11-17T00:55:37 < scrts> interesting
2014-11-17T00:55:40 < [7]> it apparently wasn't USART3 though, that one is still on
2014-11-17T00:55:41 < scrts> so ethernet works?
2014-11-17T00:55:43 < [7]> yes
2014-11-17T00:56:02 < scrts> how did you come up with the solution? trial & error?
2014-11-17T00:57:04 < [7]> your hints about the way how GPIO access is arbitrated on F1 series were a good clue ;)
2014-11-17T00:57:44 < [7]> I'm used to platforms where switching on clock gates generally doesn't hurt (except for power consumption of course), so I turned everything on while debugging, to rule out that I missed some required gate
2014-11-17T00:57:52 < [7]> turned out that was a rather bad idea on F1 ;)
2014-11-17T00:58:54 < [7]> now I'm trying to control an LED strip from an F030 MCU, and offload all the timing critical work to timers and DMA
2014-11-17T00:59:04 < [7]> however those two don't seem to want to communicate to each other :/
2014-11-17T00:59:29 < [7]> the DMA is sitting there waiting for requests, and the timer is spinning waiting for the DMA to finally set the CCR2 register
2014-11-17T01:00:22 < [7]> UDE is set, the timer also asserted UIF, but the DMA channel doesn't seem to see a request for some reason
2014-11-17T01:01:16 < [7]> this is TIM1, so the DMA request should be TIM1_UP, which is channel 5 according to the datasheet

2014-11-17T03:35:16 < kakeman> yes

2014-11-17T03:36:30 < [7]> if I set the DMA to mem2mem mode (i.e. fake requests) it start to move data around

2014-11-17T07:02:16 < dongs> why is 12V -> 0.8V for Vcore more efficient than say3.3V -> 0.8V
2014-11-17T07:02:39 < GargantuaSauce> isnt it just to minimize resistive losses
2014-11-17T07:04:01 < GargantuaSauce> that would include in the fets
2014-11-17T07:04:35 < GargantuaSauce> lower duty cycle, less current
2014-11-17T07:06:25 < GargantuaSauce> so you could for instance meter the exact usage of your video card
2014-11-17T07:06:59 < GargantuaSauce> would be very useful for software development i think

2014-11-17T13:56:54 < TheSeven> I wouldn't even say that's just ARMs... that seems to be a much broader phenomenon

2014-11-17T13:57:36 < decimad> Well I can't say as I'm new, and I think I can handle it just fine, it is just my observation that any documentation tends to stard emphasizing this fact and repeating it throughout

2014-11-17T14:01:11 < zyp> encoding higher priority as lower number is a normal convention
2014-11-17T14:01:45 < decimad> Was it inventend in gb?
2014-11-17T14:02:49 < emeryth> >insert joke about british queues
2014-11-17T14:02:58 < zyp> if I had to guess why, I'd suspect it's related to how if you sort by number, the highest priority comes first, being the lowest numbered one
2014-11-17T14:03:57 < TheSeven> ARGHHH!!!
2014-11-17T14:06:54  * TheSeven has once again searched for a problem for like a day, that turned out to be a stupid typo hidden away in some include file
2014-11-17T14:07:27 < karlp> zyp: normal for some people, not for others.
2014-11-17T14:08:12 < decimad> Maybe they only had a less-circuit and swapping input meant worse routing and they opted to save the inverter gate
2014-11-17T14:08:44 < decimad> the rest is history
2014-11-17T14:12:44 < decimad> TheSeven: Did it have to do with macros?
2014-11-17T14:13:09 < TheSeven> decimad: yes, but with the most simple and unavoidable kind
2014-11-17T14:13:18 < decimad> Name it!
2014-11-17T14:13:28 < TheSeven> #define STM32_DMA_STREAM_REGS(c, s) (*((volatile STM32_DMA_STREAM_REG_TYPE*)(0x40020008 + (c) * 0x14)))
2014-11-17T14:13:30 < TheSeven> see the problem?
2014-11-17T14:14:07 < TheSeven> should have been "s", not "c"
2014-11-17T14:14:11 < qyx_> no, why are you rewriting it?
2014-11-17T14:14:14 < dongs> um bro
2014-11-17T14:14:16 < dongs> what is this garbage
2014-11-17T14:14:28 < dongs> for sure anything in stm32fxxx.h stuff is 100% tested and working
2014-11-17T14:14:33 < dongs> if you think its wrong, then youre doing shit wrong
2014-11-17T14:15:14 < decimad> That macro is the definition of not being unavoidable ;)
2014-11-17T14:15:20 < TheSeven> well I added that one because there's just zero point in having huge switch (channel) { case 1: regs = STM32_DMA1_STERAM0_REGS; break; case 2: ... } trees everywhere
2014-11-17T14:15:32 < dongs> wait, yo u wrote that shit?

2014-11-17T14:16:09 < decimad> What would interest me most is, if the cmsis functions get optimizied to optimal code given constant arguments anyways, even though it mean filling structs before etc.
2014-11-17T14:16:13 < TheSeven> because this was, once again, just too trivial to be caught in time ;)
2014-11-17T14:16:48 < TheSeven> decimad: not at all
2014-11-17T14:17:07 < TheSeven> it could be done in such a way, but they didn't
2014-11-17T14:17:21 < decimad> hum? isn't it a compiler thing?
2014-11-17T14:17:43 < TheSeven> the standard library code copies every single field to HW regs, from a struct that has a different layout
2014-11-17T14:17:49 < TheSeven> the compiler can't do much about it
2014-11-17T14:17:56 < decimad> if it sees structure initialization by consts, then passing in const pointer and looks behind the function call it can optimize everything?
2014-11-17T14:18:18 < TheSeven> if you order the fields inside the struct nicely, and watch your use of "volatile" keywords, sometimes the compiler can actually optimize it out
2014-11-17T14:18:46 < TheSeven> it typically doesn't look that deep, and in fact it can't unless you use the "-flto" switch
2014-11-17T14:18:58 < decimad> well yeah, optimizing multiple writes to a single volatile the compiler must not do
2014-11-17T14:19:03 < decimad> read/writes
2014-11-17T14:19:19 < decimad> flto should be standard! :D
2014-11-17T14:19:28  * TheSeven agrees on that ;)

2014-11-17T14:19:57 < jpa-> a compiler could theoretically optimize it somewhat, but in practice they usually don't
2014-11-17T14:20:00 < decimad> so i will test it with maximum optimizations after lunch

2014-11-17T14:54:53 < decimad> otoh the compiler might decide not to inline because of all those reads and writes... hrmm, this is broken
2014-11-17T15:02:13 < decimad> trying to place structs through section&linker script seems unfeasible and more error prone than casting pointers... any alternative to instruct the linker from the (gcc) compiler side?
2014-11-17T15:02:56 < TheSeven> I'm not aware of any more sane solution than the #define pointer cast one
2014-11-17T15:07:50 < decimad> Pity! I mean, that it hasn't been done in 30 years shows that it's not really necessary, but in my dreams... ;)
2014-11-17T15:09:55 < jpa-> what is wrong with pointer casting in this case?
2014-11-17T15:10:18 < jpa-> or are you the kind of person who randomly picks several language features that they decide are always bad, no matter what the context?
2014-11-17T15:11:42 < jpa-> (also, volatile writes to registers directly are not exactly straightforward always.. can easily cause unnecessary accesses; the nuttx way of having separate writereg32() and readreg32() macros is one alternative)
2014-11-17T15:12:03 < jpa-> (but no matter what way you do it, it is just a tiny thing and you should be focusing your time on something else)
2014-11-17T15:13:26 < decimad> nothing is wrong, but a cast is there because the right thing (tm) wasn't defined in first place, I was just thinking loud
2014-11-17T15:15:03 < Laurenceb> but go down that road and you end up with java
2014-11-17T15:15:06 < decimad> my wishful thinking is, that a call to that gpio method would be seen as a transaction, ie. at most one read modify write per register
2014-11-17T15:16:24 < TheSeven> jpa-: one annoyance about the #define way is how it interferes with code indexers / editor autocompletion / debuggers
2014-11-17T15:17:02 < decimad> none of which a true developer needs though
2014-11-17T15:17:18 < TheSeven> oh, they can make your workflow much quicker
2014-11-17T15:17:32 < decimad> *pssst* i was just kidding
2014-11-17T15:17:58 < TheSeven> although they should really be hidden away from application code development
2014-11-17T15:18:18 < TheSeven> but sometimes you need to inspect them in the debugger, and then things can get annoying
2014-11-17T15:18:45 < decimad> Macros clutter the global namespace, they collide, they make for hard reasoning about compilation error etc. because they are not an integral part of the programming language
2014-11-17T15:18:50 < TheSeven> actually it works surprisingly well most of the time, but sometimes it doesn't
2014-11-17T15:19:33 < TheSeven> C just lacks a feature to tell the compiler/linker to place something at an absolute address
2014-11-17T15:20:29 < decimad> I can understand that, since it would couple the linker with the compiler...
2014-11-17T15:20:43 < TheSeven> oh, that would be manageable
2014-11-17T15:20:59 < TheSeven> you just need some special kind of "don't relocate this while linking" symbol type
2014-11-17T15:21:09 < decimad> sure, I mean, I came here with the "wish" it was doable, but I tend to look at the other side too ;)
2014-11-17T15:23:21 < decimad> Also I'm not sure if every generic placement of multiple instances can be expressed that way in the way we loop over registers in the current way...
2014-11-17T15:23:51 < decimad> we'd need strides and all... overcomplicating stuff maybe
2014-11-17T15:24:17 < TheSeven> structs and arrays can take care of that
2014-11-17T15:25:04 < decimad> that's what I meant with strides... for when they are interleaved with other stuff in linear address space
2014-11-17T15:25:18 < jpa-> decimad: if you use C++ (saw you talking about namespaces), then do it like zyp does in laks
2014-11-17T15:25:34 < decimad> do you have a vector?
2014-11-17T15:25:59 < decimad> sorry pointer, erm, link?

2014-11-17T15:26:21 < decimad> great thanks
2014-11-17T15:27:52 < decimad> is he colaborating or is this a one man show?
2014-11-17T15:28:28 < zyp> decimad, everything is written by me
2014-11-17T15:28:43 < TheSeven> hm, a quick look at that register/peripheral definition code suggests that it could use some constexpr constructor magic?
2014-11-17T15:29:00 < zyp> it's not completely consistent though, the style has evolved over a couple of years
2014-11-17T15:29:27 < decimad> I identified some constexpr... do you take patches, suggestions? I'd like to use that, maybe add stuff... but I dislike partitioning projects ;)
2014-11-17T15:30:31 < zyp> TheSeven, how so?
2014-11-17T15:30:35 < zyp> decimad, sure
2014-11-17T15:31:16 < decimad> Great, then count me as a user, I still need to get up to speed with constexpr since I am used to template metaprogramming where constexpr is the best alternative now
2014-11-17T15:31:50 < decimad> visual c++ you know...
2014-11-17T15:32:45 < zyp> http://cgit.jvnv.net/laks/tree/usb/descriptor.h <- I have some usb descriptor magic that uses constexpr to generate a static binary buffer from a descriptor tree
2014-11-17T15:32:50 < TheSeven> hm, I might be wrong, the one that I was looking at actually had some more intelligence (and non-constant fields) inside
2014-11-17T15:32:58 < zyp> I don't think it's very useful for generic register descriptions
2014-11-17T15:37:32 < Steffanx> I used laks a bit on L1 incl. USB worked pretty nice.
2014-11-17T15:38:23 < decimad> hrmmm, what about the thiscall on all the methods, is that optimized away?

2014-11-17T15:41:26 < jpa-> decimad: what about it would you like to get optimized away?
2014-11-17T15:42:30 < jpa-> isn't it just about passing the this pointer in one register? you would have to pass some identifier for the pin anyway
2014-11-17T15:44:30 < dongs> is c++11 even suported by any real compilers
2014-11-17T15:45:19 < emeryth> gcc is unreal?
2014-11-17T15:46:33 < PaulFertser> dongs: your favourite ms compiler supports it too, since long
2014-11-17T15:46:42 < decimad> not it doesnt
2014-11-17T15:46:46 < decimad> not in a long way
2014-11-17T15:47:58 < Steffanx> At least half of the features :P
2014-11-17T15:47:59 < decimad> visual c++ is struggles supporting initializer lists without crashing, let alone constexpr or user literals, two phase lookup...
2014-11-17T15:48:08 < PaulFertser> decimad: current msvc compiler doesn't support C++11?
2014-11-17T15:48:17 < dongs> sounds like zyp found a new C++ pal

2014-11-17T15:54:03 < decimad> jpa-: about the thiscall thingy... the const member in there basically either means the compiler can optimize the accesses or it uses a double dereference on the "this". that's what I was thinking about.
2014-11-17T15:54:53 < PaulFertser> http://blogs.msdn.com/b/vcblog/archive/2014/06/11/c-11-14-feature-tables-for-visual-studio-14-ctp1.aspx
2014-11-17T15:55:42 < decimad> then again, I'm no expert into this, but arm prefers setting a base address and then working with offsets.. maybe one could make use of that
2014-11-17T15:57:37 < decimad> to put this in context: this is the first time I really delve into getting close to a platform...
2014-11-17T15:58:24 < decimad> so basically it will be pure luck if I don't talk bs in the time coming ;)

2014-11-17T16:06:27 < decimad> Also I don't understand the recent switch to android supporting through clang from visual studio, but instead of fixing up clang for the microsoft platform, they insist on fixing their own compiler
2014-11-17T16:06:30 < zyp> kinda like premature optimization

2014-11-17T16:09:10 < decimad> zyp: this is crucial for success I believe, judging from the discussions I read in the last weeks. People are discussing about 8bit instead of 32bit because everything is waste... They prejudice on performance etc.. You can only hold up to that if you can prove that this code is exactly as effictient as if they had written to the registers manually... You can't counterfight that ;)
2014-11-17T16:09:44 < dongs> lol clang
2014-11-17T16:10:33 < decimad> dongs: will you deliver content?
2014-11-17T16:10:35 < zyp> decimad, eh, I disagree

2014-11-17T16:11:04 < decimad> heh
2014-11-17T16:11:37 < zyp> decimad, keep in mind the development time cost
2014-11-17T16:13:53 < zyp> in the end, you only need your code to be efficient enough to execute in the time you have available
2014-11-17T16:14:19 < decimad> true, but that's not really what I was arguing about
2014-11-17T16:14:39 < TheSeven> I think the point here is that some core code that's used in shitloads of applications should be as efficient as sanely possible
2014-11-17T16:15:06 < zyp> TheSeven, I agree, that's the goal I have for my library
2014-11-17T16:15:16 < zyp> with emphasis on sane
2014-11-17T16:15:36 < zyp> that's why it's all inlinable
2014-11-17T16:16:16 < Posterdati> hi
2014-11-17T16:16:36 < decimad> The point at which I started thinking was along the lines of:  gpio::configure< pinsa<1, 3, 4>, pinsb<5,2,1> >( alternate(11) | bla ) or any other syntax that would make that basic operation that happens everywhere reduce to one line
2014-11-17T16:16:38 < trepidaciousMBR> Can you read the silicon revision from CPU on an STM32F4xx?
2014-11-17T16:16:42 < Posterdati> did anyone programmed nRF51822 using stlink v2?
2014-11-17T16:17:05 < zyp> decimad, eh, that's the kind of code you don't have to optimize
2014-11-17T16:17:07 < PaulFertser> Posterdati: yes

2014-11-17T16:17:20 < PaulFertser> Posterdati: sure
2014-11-17T16:17:22 < zyp> decimad, pin configuration happens once, who cares if it takes a few instructions extra?

2014-11-17T16:17:28 < decimad> It's more about code density

2014-11-17T16:17:42 < zyp> no, code density is not as important

2014-11-17T16:17:57 < Posterdati> PaulFertser: ok
2014-11-17T16:18:00 < zyp> oh, you mean source?
2014-11-17T16:18:06 < zyp> if so, I agree
2014-11-17T16:18:19 < zyp> eliminating boilerplate is another of my goals

2014-11-17T16:42:10 < Claude> ah right , yeah saw that too . csc
2014-11-17T16:42:10 < dongs> you could put external edid eeprom

2014-11-17T16:42:21 < dongs> i *like* that it has internal stuff.
2014-11-17T16:43:07 < Claude> yes doesn't need an fpga or so for the usual stuff (e.g. connect a display)
2014-11-17T16:43:44 < dongs> its just i2c and you don't have to touch it once its loaded
2014-11-17T16:43:54 < dongs> so you could just configure all teh stuff and dump it  over i2c on startup and call it done

2014-11-17T16:51:34 < zyp> dongs, USB in itself isn't bad on latency
2014-11-17T16:52:06 < dongs> trepidaciousMBR: isnt it like mix of lot code + wafer x/y + some other trash
2014-11-17T16:52:16 < dongs> you could probly ask ST for lot codes and match revision from there..

2014-11-17T16:52:38 < karlp> rev number is actually just in the part ids,
2014-11-17T16:52:40 < dongs> i could be talking out of my ass too but I remember seeing explanation of it
2014-11-17T16:52:43 < Steffanx> afaik there is no official info about the IDs
2014-11-17T16:52:43 < karlp> no need to decode unique ids at all
2014-11-17T16:52:52 < trepidaciousMBR> dongs: I assume it's something like that, since it doesn't change much at all between chips on the same reel. I'll double check the reference manual
2014-11-17T16:52:53 < dongs> security by obscurity
2014-11-17T16:52:56 < karlp> Steffanx: there's official uniqueid docs for _some_ parts,
2014-11-17T16:53:05 < karlp> but the chip revision is a documented reg
2014-11-17T16:53:05 < Steffanx> oh, yes?
2014-11-17T16:53:37 < trepidaciousMBR> karlp: Yup we can see what id they are on the package, but it would be nice to double check from firmware, to be able to adapt to errata
2014-11-17T16:53:51 < dongs> < karlp> but the chip revision is a documented reg
2014-11-17T16:53:52 < dongs> where is it

2014-11-17T16:54:11 < dongs> the jtag idcode?
2014-11-17T16:54:19 < dongs> that changes with revisions?
2014-11-17T16:54:22 < karlp> sure,
2014-11-17T16:54:24 < karlp> read the docs :)
2014-11-17T16:54:36 < dongs> i duno man
2014-11-17T16:54:37 < karlp> athere's a chip id that's fixed, but more bits to tell the revisions apart
2014-11-17T16:54:40 < trepidaciousMBR> karlp: E.g. apparently the second half of flash on 2MB components doesn't work on STM32F437 when you use one of the USB ports, if we could detect the silicon revision we could start using it on revision 3 parts.
2014-11-17T16:54:48 < karlp> x1000 = Revision A
2014-11-17T16:54:48 < karlp> 0x1001 = Revision Z
2014-11-17T16:54:48 < karlp> 0x1003 = Revision Y

2014-11-17T16:55:00 < trepidaciousMBR> karlp: Thanks ;)
2014-11-17T16:56:13 < trepidaciousMBR> karlp: Can you read that from the core itself though, or just over JTAG?
2014-11-17T16:56:23 < karlp> what do you expect me to say to this?

2014-11-17T17:03:59 < trepidaciousMBR> dongs: Is there anything particularly extra-bad about it?

2014-11-17T17:05:13 < TheSeven> I'm still wondering what they could have messed up (at the silicon level) with that flash bank
2014-11-17T17:07:24 < trepidaciousMBR> dongs: Yup it's pretty huge, we need most of what it does though, so at least it's not as excessive as an SoC.

2014-11-17T17:18:06 < Steffanx> We already have defibrillators everywhere.
2014-11-17T17:18:21 < GargantuaSauce> the a13 is available in tqfp and definitely cheaper than f437, even in single quantities
2014-11-17T17:18:33 < dongs> yep
2014-11-17T17:18:35 < GargantuaSauce> possibly even with all required support components
2014-11-17T17:18:39 < dongs> heh
2014-11-17T17:18:48 < dongs> yeah like that DC/DC thing that allwhiner boards like to use
2014-11-17T17:18:54 < dongs> it has like 4 switchers, 5 LDOs and shit
2014-11-17T17:19:00 < dongs> and the chip is like $.80
2014-11-17T17:19:02 < GargantuaSauce> well i was thinking dram and flash
2014-11-17T17:19:20 < dongs> well yeah, but power management is there too
2014-11-17T17:19:32 < trepidaciousMBR> When we looked at a few SoCs, the total cost was a lot higher than just the SoC itself, e.g. i.mx has a pretty much required giant support IC
2014-11-17T17:19:45 < dongs> im is garbage
2014-11-17T17:19:50 < dongs> imx
2014-11-17T17:19:51 < trepidaciousMBR> We use SDRAM with 437 too, but it's pretty cheap
2014-11-17T17:20:18 < dongs> there was that imx in the chumbie hax0r board
2014-11-17T17:20:21 < dongs> i.mx23 or someshit
2014-11-17T17:20:24 < dongs> it took cheapass sdram
2014-11-17T17:20:35 < dongs> probly s ame crap you can use with f437
2014-11-17T17:20:51 < trepidaciousMBR> I think we were looking at i.mx5something
2014-11-17T17:21:05 < dongs> that one is too big/expensive
2014-11-17T17:21:09 < trepidaciousMBR> yup
2014-11-17T17:21:27 < trepidaciousMBR> Do any of the cheap ones have parallel image sensor input?
2014-11-17T17:21:33 < dongs> 23 has built in pmu
2014-11-17T17:21:36 < dongs> A13 defnitely does
2014-11-17T17:21:37 < karlp> some of them do,
2014-11-17T17:21:47 < dongs> well duno about parallel
2014-11-17T17:21:48 < karlp> some of the newer ones like a10s dropped it, because it wasn't needed
2014-11-17T17:21:50 < dongs> whats wrong wiht csi?
2014-11-17T17:21:52 < dongs> ^
2014-11-17T17:22:07 < trepidaciousMBR> We need to use a parallel image sensor
2014-11-17T17:22:33 < trepidaciousMBR> We could probably use a converter IC though

2014-11-17T17:25:38 < emeb> whoo-hoo - make sure to get your shots.
2014-11-17T17:26:14 < Claude> afaik A13 does have CSI
2014-11-17T17:26:39 < dongs> prety sure they all do
2014-11-17T17:26:40 < trepidaciousMBR> karlp: Probably nothing that knowing a lot more about Linux development wouldn't have fixed, but it just wasn't great for real-time stuff. Getting anything to run fairly predictably was tricky, and DMA performance seemed terrible, but that might have been down to the blackfin rather than linux. Also the build time is about 50 times longer ;)
2014-11-17T17:27:09 < emeb> aha - just buy SOMs from Oli
2014-11-17T17:27:10 < dongs> A10 also has undocumented mpeg2ts interface that I finally beat out of allwhiner but at that point I got bored of lunix and didnt bother to continue wiht it
2014-11-17T17:27:11 < karlp> olimex does allwinner SOMs too

2014-11-17T17:31:40 < dongs> there's at least like 5 china vendors with "8009" switcher
2014-11-17T17:33:21 < emeb> trepidaciousMBR: I hear that - digging around in kernel drivers is a serious PITA
2014-11-17T17:33:40 < dongs> Claude: so did  you actually waste time to get it working? or you're just going by the docs
2014-11-17T17:34:05 < emeb> that's one huge downside of working with any SoC that's designed for a "big" OS.

2014-11-17T17:35:24 < GargantuaSauce> sweeet
2014-11-17T17:35:30 < decimad> So hopefully you can help with with an rmII question that popped up for me studying the layout of the board at hand and considering the hal sample port for iwip... they are basically waiting on the interrupt line to check for link status update. However my board doesn't connect the phy interrupt line at all... So will I have to wait polling for link status (ie reading the phy register), since the phy is dysfunctional before link is
2014-11-17T17:35:30 < decimad>  up? This sucks... hrmmm.
2014-11-17T17:35:55 < karlp> didn't connect the irq line? sounds like you planned on polling ;)
2014-11-17T17:36:14 < GargantuaSauce> i bet they just had to keep it under wraps to keep from having to pay patent licenses to MPEG LA
2014-11-17T17:36:19 < trepidaciousMBR> emeb: Yup, the 437 image sensor "driver" is basically just setting some registers and starting a DMA, and it works perfectly :)
2014-11-17T17:36:47 < decimad> I didnt, I'm using a sample board... and PWR_DOWN/INT is not connected according to layout -.-
2014-11-17T17:37:32 < dongs> GargantuaSauce: pllllzzzz
2014-11-17T17:37:45 < dongs> GargantuaSauce: the whole Axx is probably chock-full of stolen IP

2014-11-17T17:40:11 < Claude> dongs, yes thats my impression too. frankenstein'ed SoC with every IP allwinner could get their hands on
2014-11-17T17:40:35 < decimad> But if I understand it correctly, then the rx lines run synchronously anyways, the phy does not "alert" on data, does it? The interrupts are just for organizatorial status updates?
2014-11-17T17:40:51 < Claude> e.g. GPS baseband in build in too

2014-11-17T18:48:56 < TheSeven> decimad: there's no standard way of getting a phy to generate an IRQ
2014-11-17T18:49:16 < TheSeven> i.e. you need a phy-specific driver to do that, and it will take up an additional pin
2014-11-17T18:49:45 < TheSeven> polling is just easier for most purposes, especially given that you can usually get away with a rather low polling rate if you only want to know if someone plugged in a cable
2014-11-17T18:51:30 < decimad> Yup, I can live with it. It's just that I didn't feel pointed to this fact and fell into the curious-mode "what the fuck is going on here?"
2014-11-17T18:52:01 < TheSeven> I'd say it's an oversight from back when that spec was made
2014-11-17T18:52:05 < decimad> This would be the first thing I would document above the polling code...
2014-11-17T18:52:33 < TheSeven> heh, I guess everyone who's dealing with the guts of ethernet drivers is just aware of that fact anyway ;)
2014-11-17T18:52:47 < decimad> Except the one that wants to work his way into it
2014-11-17T18:52:55 < TheSeven> as with lots of things out there
2014-11-17T18:53:24 < decimad> I happen to find that often, yes, that makes me document every thing that is unusual on the way
2014-11-17T18:54:39 < decimad> But nice to know that I could save on threads if I read the phy docs correctly
2014-11-17T18:54:46 < decimad> If I ever have to
2014-11-17T18:57:56 < decimad> Do people really program mcus without knowing what is going on there? I can't possibly believe that...

2014-11-17T23:37:53 < decimad> Well, if I hadn't looked into their source, I wouldn't be aware of the implied synching because the mac core runs at a different clock. I wouldn't really wait a millisecond after each write, but this I learned from it.

2014-11-17T23:41:43 < Posterdati> please help, I installed wrong crystal on stm32 (25 MHz but CL = 18 pF) may I use 47 pF capacitance to make it go?
2014-11-17T23:42:44 < zyp> huh?
2014-11-17T23:42:51 < zyp> you're not making sense
2014-11-17T23:43:03 < Posterdati> ?
2014-11-17T23:43:23 < zyp> what do you mean «wrong crystal»?
2014-11-17T23:43:30 < decimad> my understanding is he has a crystal specified fpr 18pF load capacitance, but he only has 49pF capacitators
2014-11-17T23:43:43 < Posterdati> decimad: yes
2014-11-17T23:43:46 < zyp> that's not how I read it
2014-11-17T23:44:12 < Taxman> 49 pF in parallel makes around 24 pF
2014-11-17T23:44:16 < zyp> target load capacitance for a crystal with a C_L of 18pF would be 36 pF
2014-11-17T23:44:22 < Posterdati> 47 pF
2014-11-17T23:44:28 < zyp> capacitors maybe a little lower to account for trace capacitance
2014-11-17T23:44:31 < Taxman> so you are not too far away from destination
2014-11-17T23:44:39 < Posterdati> yes, but no 36 pF here

2014-11-17T23:45:07 < Posterdati> yes
2014-11-17T23:45:12 < zyp> 47 pF may skew your frequency a bit, but depending on what it's used for, it might not matter
2014-11-17T23:45:15 < Taxman> i think it should run
2014-11-17T23:45:39 < zyp> a bit = a few tenths of a percentage
2014-11-17T23:45:50 < Posterdati> nice
2014-11-17T23:46:45 < decimad> Do those processory work with a hand driven clock btw? Is even clocking crucial? :)

2014-11-17T23:48:07 < zyp> a wrongly loaded HSE would probably still be more accurate than HSI
2014-11-17T23:48:10 < decimad> Was just a quick amusing thought... yes, a push button...
2014-11-17T23:48:38 < zyp> decimad, good luck deriving any communication clocks from that

2014-11-17T23:50:01 < decimad> but I mean, apart from the obvious interfacing problems... does the mcu care internally?
2014-11-17T23:50:51 < Taxman> the pll cares
2014-11-17T23:51:00 < Taxman> it would not lock
2014-11-17T23:52:05 < decimad> you can bypass that one, if I remember the manual correctly...

2014-11-18T00:53:24 < kakeman> anything cool today?
2014-11-18T00:53:36 < zyp> nah
2014-11-18T00:54:24 < karlp> got libopencm3 miniblink and rcc up on the l053 disco, that's progress for me :)
2014-11-18T00:54:41 < karlp> trivial mechanical work I guess, but progress :)
2014-11-18T00:55:30 < Taxman> nice
2014-11-18T00:55:50 < englishman> I made a one line pullreq
2014-11-18T00:56:04 < englishman> Big day.
2014-11-18T00:57:48 < kakeman> that's best kind of progress that something happens

2014-11-18T01:30:29 < brabo> TheSeven: sorry to bug you, i'm trying to get ethernet working on the stm32f107 and having problems, and i saw you talking about figuring that one out couple days ago.. any chance yu could share woring code?
2014-11-18T01:30:56 < TheSeven> brabo: what kind of problem are you running into?
2014-11-18T01:31:21 < TheSeven> I might have some hints if I know what to look for ;)
2014-11-18T01:33:25 < brabo> TheSeven: something not right with initialization i think.. i decided to try to make libopencm3's ethernet part working on it, so i've treid porting the demo eth driver from st to it, and to make it simpler, i am also trying to make picotcp work with it.. the phy link reports up, no packets are getting sent tho
2014-11-18T01:34:00 < TheSeven> so you're attempting to send something and it never ends up on the wire?
2014-11-18T01:34:06 < brabo> indeed
2014-11-18T01:34:20 < TheSeven> do the "own" bits in the DMA descriptors get reset to zero by the hardware?
2014-11-18T01:34:54 < brabo> hat's a good question, lemme have a look and get back to you

2014-11-18T01:37:36 < TheSeven> also, is the hardware known working?
2014-11-18T01:37:48 < TheSeven> do phy and mac speed/duplex settings match?
2014-11-18T01:38:26 < TheSeven> do you get any signal edges on the TX_EN line? (those should be slow enough to see spikes even with a crappy scope)
2014-11-18T01:38:31  * TheSeven is away for a few minutes
2014-11-18T01:38:34 < brabo> the hardware is known working, it is a stm3210c-eval board which works with the demo webserver
2014-11-18T01:38:45 < brabo> aha scoping th e connector, can try that too

2014-11-18T01:51:40 < brabo> TheSeven: the eth_tx routing checks for: if (ETH_DES0(TxBD) & ETH_TDES0_OWN), this condition is false, so i guess the wn bit has been reset right?
2014-11-18T01:52:18 < TheSeven> that's the check that determines if the descriptor is free - which is its initial state
2014-11-18T01:52:30 < TheSeven> what I'm wondering is whether that bit actually gets reset once the software sets it
2014-11-18T01:53:02 < brabo> ah i can just check directly after the set or?
2014-11-18T01:53:18 < brabo> it gets set during eth_desc_init
2014-11-18T01:54:04 < TheSeven> hm, it should get cleared in there (for TX descriptors)
2014-11-18T01:54:24 < TheSeven> at least if I remember correctly
2014-11-18T01:54:43 < brabo> ETH_DES0(bd) = ETH_RDES0_OWN;   is in there
2014-11-18T01:54:48 < brabo> nothing for the tx
2014-11-18T01:54:54 < TheSeven> sending a packet should set it - give it a few milliseconds after that and check if the hardware has cleared it again
2014-11-18T01:55:29 < brabo> but uhm, i tested in eth_rx and there the own bit is still set
2014-11-18T01:55:49 < TheSeven> could be possible that the RX side own bit is inverted
2014-11-18T01:55:51 < brabo> it's not being set or reset in desc_init.. should it?
2014-11-18T01:56:01 < TheSeven> but for now I'm concerned about TX
2014-11-18T01:56:30 < brabo> yea send out would be nice already.. lemme check phy and mac settings, brb

2014-11-18T02:26:42 < brabo> TheSeven: i am setting FES and DM after i get back from phy_link_status that the phy is in 100m ful duplex mode, altho i do see that the datasheet says FES indicates the speed in Fast Ethernet (MII) mode
2014-11-18T02:27:02 < brabo> but i'm working in rmi mode, i didn't find anything about that
2014-11-18T02:27:12 < TheSeven> that's just a datasheet inaccuracy
2014-11-18T02:27:14 < TheSeven> it applies to both modes
2014-11-18T02:27:48 < brabo> aha okay
2014-11-18T02:28:01 < brabo> then those should be correct i guess..
2014-11-18T02:28:23 < TheSeven> ok, can you read out the DMASR after attempting to send some packets?
2014-11-18T02:28:35 < TheSeven> I'm especially curious about the RPS and TPS fields
2014-11-18T02:29:10 < brabo> can do :)
2014-11-18T02:30:59 < TheSeven> "Error: instruction not supported in Thumb16 mode -- `adds r6,#1'" - what the hell is wrong with that instruction? according to the ARMv6-M ARM there is a 16bit thumb ADDS <Rd>,<Rn>,#<imm3> instruction
2014-11-18T02:31:12 < TheSeven> and no, duplicating the r6 doesn't help
2014-11-18T02:32:13 < TheSeven> there's also ADDS <Rdn>,#<imm8>

2014-11-18T02:43:07 < TheSeven> set to what value?
2014-11-18T02:43:44 < brabo> they are both set in DMASR

2014-11-18T02:43:52 < brabo> they can only be 0 or 1 no=
2014-11-18T02:44:05 < TheSeven> they're 3 bit wide each
2014-11-18T02:44:10 < brabo> oooh
2014-11-18T02:44:18 < brabo> i'm just testing with &
2014-11-18T02:44:26 < brabo> sec
2014-11-18T02:53:00 < brabo> TheSeven: RPS: bit 17 and 18 set, TPS bit 20 set
2014-11-18T02:53:30 < brabo> i guess i tested the first position before, so that makes sense?
2014-11-18T02:54:46 < TheSeven> ok, so it looks like the MAC clocks are running and the state machine is operating
2014-11-18T02:54:54 < TheSeven> hm... maybe check the GPIO config?
2014-11-18T02:55:09 < TheSeven> ah, you're on F1... might as well be the same issue that I ran into then
2014-11-18T02:55:19 < TheSeven> which peripheral clocks do you have powered up?
2014-11-18T02:55:32 < TheSeven> try keeping those to a minimum, and double-check the AFIO regs
2014-11-18T02:56:02 < brabo> gpioa-b-c-d afio and usart2
2014-11-18T02:56:21 < brabo> am also setting the afio flag for rmi mode
2014-11-18T02:57:52 < TheSeven> hm, there must be more clocks powered up, e.g. ethernet
2014-11-18T02:58:17 < TheSeven> and I don't mean the MII mode field, but the other AFIO peripheral remap fields which might conflict with the ethernet core's pins

2014-11-18T02:59:04 < brabo> they are on
2014-11-18T03:00:36 < TheSeven> I'm not talking about the ones that you explicitly turn on, but also any other crap that might have been on before already
2014-11-18T03:07:08 < brabo> mmm hw can i find out and/or turn off everything before explicitly setting them?
2014-11-18T03:07:40  * brabo is pretty new to microcontroller programming and especially the stm32
2014-11-18T03:07:54 < brabo> so forgive my noobness ;)
2014-11-18T03:09:59 < brabo> ah i am also remapping usart2
2014-11-18T03:10:24 < brabo> that should be good if i understood it correctly?
2014-11-18T03:25:06 < TheSeven> I don't know that from the top of my head right now - but generally just shut off stuff that you don't absolutely need and ensure that there are no pin conflicts

2014-11-18T11:44:44 < Cyric> hey guys, if i want to change the value of the RTC WAKE up counter
2014-11-18T11:44:55 < Cyric> what i have to do?
2014-11-18T11:45:13 < Cyric> changing it in real time application...
2014-11-18T11:45:14 < akaWolf> read DS?
2014-11-18T11:45:15 < Cyric> RTC_SetWakeUpCounter(readintvalue(SLEEPTIME_add));
2014-11-18T11:45:43 < Cyric> basically that readintvalue is reading a value from EEPROM

2014-11-18T11:46:04 < akaWolf> i.e. reading of the DS isn't a variant..
2014-11-18T11:47:07 < Cyric> what is DS
2014-11-18T11:47:26 < Cyric> i think the register is RTC->WUTR
2014-11-18T11:47:28 < akaWolf> I think, it maybe DataSheet
2014-11-18T11:47:37 < akaWolf> but I'm not sure
2014-11-18T11:48:04 < akaWolf> it's so ancient thing..
2014-11-18T11:49:39 < zyp> Cyric, which chip?
2014-11-18T11:49:45 < Cyric> stm32l
2014-11-18T11:49:47 < Cyric> 151
2014-11-18T11:49:48 < zyp> dongs, are you around?
2014-11-18T11:50:06 < Cyric> do i have to restart the rtc?
2014-11-18T11:51:17 < Cyric> probably will be enouth
2014-11-18T11:51:19 < Cyric> to RTC_WakeUpCmd(DISABLE)
2014-11-18T11:51:44 < Cyric> then RTC_SetWakeUpCounter(new value)
2014-11-18T11:52:06 < Cyric> yes i am almost sure now
2014-11-18T11:56:49 < dongs> zyp: ya
2014-11-18T11:57:08 < dongs> pcbs?
2014-11-18T11:57:35 < zyp> yes, in a moment
2014-11-18T11:58:01 < dongs> you can just email
2014-11-18T11:58:07 < dongs> not sure if anything can be done wiht them today
2014-11-18T11:58:15 < zyp> no hurry
2014-11-18T12:02:28 < zyp> also considering doing a silly little l0 based design while I'm at it
2014-11-18T12:02:49 < dongs> l0?
2014-11-18T12:02:56 < dongs> pfft
2014-11-18T12:03:03 < dongs> enjoy timecube
2014-11-18T12:03:20 < zyp> hah, as if
2014-11-18T12:03:48 < zyp> why would lack of stdperiph be an issue when I wouldn't use it in the first place? :p
2014-11-18T12:05:02 < jpa-> dongs: how is timecube worse than stdperiph (a few months back i would have asked "how could you possibly make stdperiph worse?")

2014-11-18T13:09:20 < dongs> or that
2014-11-18T13:11:04 < decimad> thanks, could find it
2014-11-18T13:12:48 < decimad> The most I did recently was 30 builds on a day... and obviously I was unconcentrated... that would last a year minimum... better than debugging in ram^^
2014-11-18T13:13:30 < zyp> dongs, hmm, so I should design with qfp48 even for a board that'll use like five gpios?
2014-11-18T13:15:18 < dongs> yeah
2014-11-18T13:15:19 < jpa-> you can put leds on the rest
2014-11-18T13:15:21 < dongs> its probly cheaper, too
2014-11-18T13:15:35 < jpa-> if you use dma to blink them, there is not much overhead
2014-11-18T13:15:42 < decimad> are the additional gpios on new banks? are some peripheral spread across the banks? could mean more power consumption?
2014-11-18T13:15:57 < jpa-> peripherals can be disabled individually
2014-11-18T13:16:05 < jpa-> i don't think they consume much energy when disabled
2014-11-18T13:16:17 < decimad> nah I mean when you need to clock more banks
2014-11-18T13:16:33 < dongs>  idoubt he really caresabout l0w power part of l0..
2014-11-18T13:17:02 < zyp> decimad, the chip die is probably the same inside both
2014-11-18T13:17:09 < jpa-> decimad: usually within one STM32 chip with different pin count, they just remove some pins without changing peripheral mappings
2014-11-18T13:17:10 < zyp> just with fewer bonding pads hooked up
2014-11-18T13:18:09 < dongs> yeah
2014-11-18T13:18:16 < decimad> well, that makes the decision easier ;)
2014-11-18T13:18:20 < dongs> they evne go as far as not bothering disabling shit like ethernet
2014-11-18T13:18:22 < dongs> on F205
2014-11-18T13:18:28 < dongs> and just keep it, like on F207
2014-11-18T13:18:36 < dongs> and STM32F103C8 has 128k of flash
2014-11-18T13:18:40 < dongs> even tho flash_size returns 64

2014-11-18T13:42:31 < dongs> I use RT9193 MCP1804 LP2992 etc, all same pinout
2014-11-18T13:42:41 < dongs> SPX3819
2014-11-18T13:42:44 < dongs> latter 3 have wider Vin
2014-11-18T13:43:49 < madist> zyp: 1117 is available in smaller that SOT-223
2014-11-18T13:44:01 < madist> (don't remember the name of the package)
2014-11-18T13:46:12 < zyp> dongs, i.e. sot-23-5?
2014-11-18T13:46:17 < dongs> ^ those above
2014-11-18T13:46:36 < zyp> madist, right now I only care about the footprint
2014-11-18T13:48:14 < zyp> hmm
2014-11-18T13:48:31 < zyp> dongs, looks like the enable pin position is not consistent between them
2014-11-18T13:48:45 < dongs> it is, oops disregard MCP
2014-11-18T13:48:47 < zyp> some have it on 3, some have it on 4
2014-11-18T13:48:48 < dongs> its MCP1802
2014-11-18T13:48:50 < dongs> for correct one
2014-11-18T13:48:54 < zyp> oh, ok
2014-11-18T13:48:55 < dongs> no, tehy are all pin compatible
2014-11-18T13:49:01 < dongs> 1804 is something esel
2014-11-18T13:49:13 < zyp> yeah, ok
2014-11-18T13:49:38 < zyp> I guess I can just leave the enable pin unconnected if I don't need it?
2014-11-18T13:49:48 < zyp> or do I need to tie it to vin?

2014-11-18T15:06:10 < karlp> (just updated to add rt9193)
2014-11-18T15:08:37 < zyp> okay
2014-11-18T15:08:47 < zyp> right now I were just interested in the footprint
2014-11-18T15:08:56 < Steffanx> karlp, maybe it's an idea to add images to that repo too: http://i.imgur.com/hmOJSMd.png is gone now.
2014-11-18T15:09:33 < karlp> sorry, what was that image?
2014-11-18T15:09:41 < Steffanx> the "dongs-encoder-wiring"-zypsnip
2014-11-18T15:09:48 < TheSeven> this code somehow generates a read to the register (right before writing zero to it)
2014-11-18T15:09:48 < TheSeven>     volatile STM32_TIM_REG_TYPE* t = timer_regs[config->timer];
2014-11-18T15:09:48 < TheSeven>     t->RCR = 0;
2014-11-18T15:09:48 < TheSeven> however, if I replace "config->timer" with "0", it doesn't.
2014-11-18T15:09:48 < TheSeven> that seems rather weird...
2014-11-18T15:15:18 < karlp> Steffanx: oh, thanks.

2014-11-18T15:21:33 < dongs> https://github.com/karlp/zypsnips/blob/master/crystal-load-wisdom.txt haha
2014-11-18T15:22:12 < karlp> should actually add zyps actually useful "how to work out crystal caps from load specs" rule of thumb some time though
2014-11-18T15:22:51 < dongs> <kevtris> the rule of thumb is about like this:  47pf for 1MHz to 4MHz...  33pf for 4MHz to 12MHz or so, 22pf for 12MHz to 25MHz
2014-11-18T15:23:08 < dongs> thats in my crystal.txt
2014-11-18T15:23:16 < dongs> but really i just use 18pF everywehre.
2014-11-18T15:23:20 < dongs> cuz thats what I have on a reel
2014-11-18T15:24:00 < qyx_> 22pF here
2014-11-18T15:24:03 < qyx_> never had any problem
2014-11-18T15:24:26 < dongs> 18pF is also a compensation cap for 2 standard switchers that I use
2014-11-18T15:24:32 < dongs> so that saves me bom cost even more
2014-11-18T15:27:13 < TheSeven> so why does typeof(&(timer->RCR)) rcr = &(timer->RCR); *rcr = 0; generate more efficient core than just timer->RCR=0; !?
2014-11-18T15:27:57 < dongs> wuat
2014-11-18T15:28:04 < dongs> proof or it didnt happen
2014-11-18T15:28:38 < TheSeven> the first is just str     r6, [r3, #48]
2014-11-18T15:28:57 < TheSeven> the second is this:
2014-11-18T15:28:58 < TheSeven> ldr     r2, [r3, #48]
2014-11-18T15:28:58 < TheSeven> str     r6, [r3, #48]
2014-11-18T15:29:05 < TheSeven> with r2 getting discarded

2014-11-18T15:29:16 < dongs> spotted your problem
2014-11-18T15:29:58 < TheSeven> and all of this only happens if the value of timer isn't discovered to be constant
2014-11-18T15:31:14 < decimad> gcc arm embedded? they're quick if you file a bug report i think...

2014-11-18T15:35:11 < decimad> I ask myself, how did you come up with that "optimization" ?
2014-11-18T15:35:56 < TheSeven> decimad: yes
2014-11-18T15:36:04 -!- phantoxe [~destroy@2a02:4780:1:1::1:123c] has joined ##stm32
2014-11-18T15:36:25 < TheSeven> well I basically messed with it, looking at the disassemblies, until I found one that looked sane
2014-11-18T15:36:29 < decimad> i think typeof might strip decorators
2014-11-18T15:36:42 < decimad> maybe it strips volatile and there's a volatile bug...
2014-11-18T15:36:53 < TheSeven> no, I don't think it strips the volatile
2014-11-18T15:37:10 < decimad> I can't tell, since typeof is non-standard... what happens with decltype?
2014-11-18T15:37:12 < TheSeven> and if so, it should strip it here as well: *((typeof(&(timer->RCR)))&(timer->RCR)) = 0;
2014-11-18T15:37:27 < TheSeven> and that generates the inefficient version as well
2014-11-18T15:37:41 < TheSeven> the intermediate variable must be playing a role somehow
2014-11-18T15:39:17 < TheSeven> volatile typeof(timer->RCR)* rcr = &(timer->RCR); *rcr = 0; generates the efficient version
2014-11-18T15:39:31 < TheSeven> so it likely isn't related to volatility
2014-11-18T15:40:08 < TheSeven> actually I just used the typeof to rule out any error on my side, it behaves the same if I just make it volatile uint32_t*
2014-11-18T15:40:51 < decimad> are you aware that typeof is a "deprecated extension" and should be superseded with standard decltype?
2014-11-18T15:41:16 < TheSeven> if I disable the optimization, it generates code along the lines of *var = ((*var) & 0) | new_value;
2014-11-18T15:41:23 < decimad> this does not bring anything to the problem at hand obviously, i just wanted to mention

2014-11-18T15:41:54 < TheSeven> so that's likely where the spurious read comes from
2014-11-18T15:42:12 < TheSeven> and as the thing is volatile it won't kill the read during later optimization steps
2014-11-18T15:42:34 < TheSeven> but why does it generate that nonsense in the first place, and only in some situations?
2014-11-18T15:43:02 < decimad> either crystal ball or bug report ;)
2014-11-18T15:44:36 < TheSeven> one thing to note is that the spurious read isn't there even with -O0 (as expected)
2014-11-18T15:45:05 < karlp> dongs: pretty sure that rule of thumb for crystals based on speeds is totally wrong.
2014-11-18T15:45:45 < karlp> it's something like CL/2 or something, but definitely not based on speed
2014-11-18T15:46:40 < dongs> karlp: but CL changes with speed
2014-11-18T15:47:35 < dongs> i duno man, i just retweet
2014-11-18T15:47:48 < dongs> fucking altium
2014-11-18T15:47:50 < jpa-> based on speed is fine to choose between 32kHz and 8 MHz
2014-11-18T15:48:02 < dongs> alt-f4 even when you have windows open on separate monitors closes them ALL
2014-11-18T15:48:04 < jpa-> if you want to be more accurate than that, better look at the datasheet
2014-11-18T15:48:22 < karlp> I thought CL was just a datasheet figure, not something that depended on speed

2014-11-18T15:50:28 < decimad> I can't imagine how they're not strongly connected on the physical modelling of what happens
2014-11-18T15:50:31 < TheSeven> with stray_cap being mostly guesswork, hence rules of thumb ;)
2014-11-18T15:50:46 < karlp> just on digikey, 12mhez shows me 8pf-32pf
2014-11-18T15:51:22 < decimad> frequency is a function of crystal size... and then potential energy is connected with cap size
2014-11-18T15:52:13 < karlp> 12pf-30pf all on the first page sorted by price, so I don't how it's reasonable to just say, "xpf for x Mhz"
2014-11-18T15:52:46 < madiz> decimad: frequency is a function of crystal size for a given thickness of a given cut
2014-11-18T15:53:00 < madiz> open a 12MHz HC49 and 5mm smd 12MHz and see
2014-11-18T15:53:29 < decimad> are they still connected?
2014-11-18T15:53:37 < decimad> there are more variables obviously
2014-11-18T15:54:51 < decimad> anyways, if those parameters are given, you wouldn't need the cl datasheet value, or you basically can deduce the other parameters from frequency and given cl i guess
2014-11-18T15:55:27 < madiz> I don't think the value of the capacitor has anything to do with the crystal dimensions.
2014-11-18T15:57:31 < jpa-> it probably has, but not the major dimensions but some minor adjustments like connecting pad size

2014-11-18T15:57:54 < jpa-> but yeah, like karlp said, same freq is available in many capacitances
2014-11-18T15:58:23 < madiz> why pad size ?
2014-11-18T15:58:37 < jpa-> and if you don't care about accuracy, the caps can be just "something 5-20 pF"
2014-11-18T15:58:59 < jpa-> madiz: the pad connecting to the crystal inside the crystal enclosure
2014-11-18T16:01:40 < decimad> unfortunately it's hard to find a good in-depth article about quartz oscillators
2014-11-18T16:02:53 < decimad> and obviously hard is universally defined by "what decimad is not able to do".
2014-11-18T16:03:21 < madiz> the best articles I've seen were on the sites of some US crystal vendors.

2014-11-18T16:04:35 < TheSeven> I need to come up with a more simple test case for that...
2014-11-18T16:05:06 < decimad> wont any volatile global do?
2014-11-18T16:05:29 < TheSeven> the problem goes away if the compiler can figure out where it actually is
2014-11-18T16:05:35 < TheSeven> might need an extern symbol or something
2014-11-18T16:05:50 < TheSeven> hm, or maybe it could be sufficient if the address is only determined at link time

2014-11-18T18:13:42 < decimad2> it seems "optimization for size" does not want to inline
2014-11-18T18:14:13 < decimad2> which sounds logical at first, but then it misses the point that everything is static and optimize for speed will produce less code

2014-11-18T18:26:08 < dongs> im sure thats better than stdperiphlib
2014-11-18T18:27:01 < dongs> i dont even understand what the  C++11 line supposed to do
2014-11-18T18:27:28 < TheSeven> hm... why all these pointless constant loads?
2014-11-18T18:27:54 < TheSeven> are the regs behind those defined as a struct?
2014-11-18T18:28:10 < decimad2> i guess the l2 and all are the gpio base register adresses and the constants in the instructions are offsets
2014-11-18T18:28:18 < TheSeven> it should really use str Rx, [Ry,Rz]-type instructions
2014-11-18T18:28:38 < TheSeven> or rather Rx, R[y,#imm]
2014-11-18T18:29:10 -!- edmont [~edmont@router.cedint.upm.es] has quit [Ping timeout: 256 seconds]
2014-11-18T18:29:27 < TheSeven> it looks like it is generating a constant pool entry for every single GPIO reg
2014-11-18T18:30:44 < decimad2> yes it does... 6 absolute addresses
2014-11-18T18:31:04 < decimad2> instead of 2 and relative adressing
2014-11-18T18:31:04 < TheSeven> seems rather pointless
2014-11-18T18:31:07 < TheSeven> why is it doing that?
2014-11-18T18:31:17 < TheSeven> i.e. how are the regs declared?
2014-11-18T18:31:51 < decimad2> i hacked it up quickly, my concerns was inlining and all... let me see
2014-11-18T18:32:14 < decimad2> volatile char* const port_base = reinterpret_cast<volatile char*>(0x40020000) + port * 0x400;
2014-11-18T18:32:40 < decimad2> I could add the port to each access... maybe that helps...
2014-11-18T18:33:08 < TheSeven> how are the individual regs inside the core declared?
2014-11-18T18:33:36 < TheSeven> I think it might make sense to make that thing actually a volatile struct something* const port_regs = ...
2014-11-18T18:33:37 < decimad2> you mean "volatile uint32* const mode = reinterpret_cast<volatile uint32*>(port_base + 0x00);"?
2014-11-18T18:33:47 < TheSeven> ah right
2014-11-18T18:33:54 < TheSeven> well, that might be a problem
2014-11-18T18:35:16 < decimad2> any ideas? I would think the compiler looks at the accessesd addresses, and sees if it can combine accesses with relative instructions?
2014-11-18T18:36:27 < TheSeven> no, in my experience it doesn't seem to do that in most of the cases
2014-11-18T18:37:00 < TheSeven> declaring the whole GPIO port's regs as one struct, and accessing its members, seems to work better usually
2014-11-18T18:37:04 < decimad2> but there's no technical reason not to, right?
2014-11-18T18:37:29 < TheSeven> it probably loses track of how these values correlate
2014-11-18T18:37:53 < TheSeven> constant propagation wins over common subexpression detection
2014-11-18T18:38:18 < decimad2> Then it's not well adapted to arm just yet, it seems
2014-11-18T18:38:28 < decimad2> erm, to thumb
2014-11-18T18:38:49 < decimad2> well anyways, I can change the access style of course
2014-11-18T18:39:02 < decimad2> but the code reduces well, that's what I wanted to find out
2014-11-18T18:39:05 < TheSeven> this kind of thing typically happens at an architecture-independent layer of the compiler
2014-11-18T18:40:20 < decimad2> seems reasonable to do a sweep through all functions optimizing this as one of the last steps...

2014-11-18T18:42:42 < decimad2> I could probably get rid of the template alltogether and the compiler could still optimize it...
2014-11-18T18:43:03 < dongs> i dont see waht youreyt triyng to do
2014-11-18T18:43:56 < dongs> whats the significance of first portpins<> vs the 2nd one
2014-11-18T18:44:02 < dongs> same number (5) is repeated there twice
2014-11-18T18:44:34 < decimad2> The portpins list selects pins of ports, the function arguments are for the config
2014-11-18T18:44:58 < dongs> take 2 minutes to make twitter better work for you
2014-11-18T18:45:18 < decimad2> hrmm?
2014-11-18T18:45:24 < dongs> what pins of ports
2014-11-18T18:45:28 < dongs> how do you specify GPIOA/B/C etc
2014-11-18T18:45:42 < decimad2> gpioa = port_pins< 0, ... >
2014-11-18T18:45:48 < decimad2> I can provide typedefs...
2014-11-18T18:46:08 < dongs> so your shit turns on PA2,3,4,5 and PB5,6,7?
2014-11-18T18:46:13 < decimad2> yes
2014-11-18T18:46:27 < decimad2> that's just some fucked up example...
2014-11-18T18:46:41 < dongs> only marginally better than doing shit like GPIOA->FGTR = 0x7A693333; // no comment here
2014-11-18T18:47:27 < decimad2> well, it's 6 register writes, we agree on that, right?
2014-11-18T18:48:47 < decimad2> it's just one line and doesn't contain any magic constants whatsoever... I find it a win for parsing the code later-on

2014-11-18T19:33:15 < Steffanx> The template magic is just.. meh
2014-11-18T19:33:33 < decimad2> steffanx: where's the magic? :)
2014-11-18T19:36:25 < decimad2> steffanx: in this case i couldn't come up with a simpler way to handle "statically dynamic-sized" lists than this, for the config itself, constant propagation is available
2014-11-18T19:36:51 < Steffanx> No, maybe not, but i still dislike it :)
2014-11-18T19:37:15 < Steffanx> i think someone else here did something similar
2014-11-18T19:37:19 < Steffanx> but i dont remember who
2014-11-18T19:37:27 < decimad2> maybe he was driven out ;)
2014-11-18T19:38:00 < Steffanx> Actually he was.
2014-11-18T19:38:15 < Steffanx> unless you are Erlkoenig
2014-11-18T19:38:36 < decimad2> Why would I write the same templates twice?
2014-11-18T19:39:40 < Steffanx> I don't know, maybe you lost your code? Decided to start over and joined here in disguise.
2014-11-18T19:39:47 < decimad2> But granted, it's unlikely to meet people that are not somewhat disgusted by templates that are more than plain std::vector or something.
2014-11-18T19:41:28 < decimad2> I would even like boost, if it wasn't for all the functionality that still uses workarounds instead of c++11...

2014-11-18T19:56:14 < zyp> you saw my fpga example yesterday
2014-11-18T19:56:49 < decimad2> it's shorter, it's faster, it's pointless!
2014-11-18T19:57:29 < zyp> how would you define a named group of pins for reuse?
2014-11-18T19:58:21 < decimad2> I did not design for it... but you could typedef a typelist for it... it would unpack that one
2014-11-18T19:58:42 < decimad2> so it's doable easily on top, I just did not design for it
2014-11-18T19:59:23 < zyp> why didn't you design for something that's actually useful? stop distracting yourself with pointless bullshit
2014-11-18T19:59:48 < decimad2> now you're insulting without reason!
2014-11-18T20:00:59 < decimad2> If i quickly hack smth. together as a proof of concept in 20 mins it obviously won't stand the critics ;)

2014-11-18T20:07:33 < zyp> I'm sorry, I think you're just focusing too much on something that's not a performance killer, and not enough on readability
2014-11-18T20:07:55 < decimad2> I'm not focusing on performance here!
2014-11-18T20:08:01 < decimad2> It's just a byproduct
2014-11-18T20:09:19 < decimad2> I mean, if there is something that makes this harder to understand than a multi line expression with arrays, then I'm interested obviously

2014-11-18T20:15:00 < decimad2> dude, you make me parse and understand your code now, that could take some time...
2014-11-18T20:16:38 < zyp> those are plain gpios
2014-11-18T20:16:41 < zyp> arrays of gpios
2014-11-18T20:16:53 < zyp> which are read and written at different points in the code
2014-11-18T20:17:29 < zyp> the reason I like naming all my pins is twofold
2014-11-18T20:18:12 < zyp> it's partly because I like the code to explain what it does, and partly because I don't want to carry around the actual pin number everywhere
2014-11-18T20:18:35 < zyp> so I define all pins in one part of the source file, and use names elsewhere
2014-11-18T20:20:09 < zyp> using templates like you do may be cute, but it's a hassle when you want to pass pins as arguments into functions

2014-11-18T21:38:14 < karlp> as a C user, I can read and understand zyps, but decimads is like you wanted to use templates no matter what.

2014-11-18T21:41:08 < decimad2> zyp: can't really argue on that level, karlp: my use of real arguments instead of template arguments should show that I tried to avoid where possible. I found no nice way to construct "dynamically" sized lists though (every pin has the same config set but you may want to treat any number of pins equally).
2014-11-18T21:42:11 < decimad2> karlp: so it's just runtime array vs. compile time type list... that's all the difference.
2014-11-18T21:42:33 < zyp> decimad2, you can use variadic templates implicitly
2014-11-18T21:43:11 < decimad2> I could create a tag argument containing the same information as the template parameters, yes
2014-11-18T21:45:15 < decimad2> something like configure( addr_pins() | data_pins(), alternate(12) |  high_speed ). That's no obvious win though for me currently.
2014-11-18T21:46:05 < decimad2> Or even pins::configure( alternate(12) | high_speed ).
2014-11-18T21:47:03 < zyp> I mean, you could do something like this: http://paste.jvnv.net/view/GWuVW
2014-11-18T21:47:24 < zyp> why is addr_pins and data_pins even functions?
2014-11-18T21:48:18 < decimad2> Using constructors was just a quick way to make them objects for the operator usage

2014-11-19T01:33:51 < KreAture_> It grows 4 bytes by the addition and is less than 40k in size

2014-11-19T01:34:26 < KreAture_> add a tiny bit more code and it fails again
2014-11-19T01:34:28 < KreAture_> LOL
2014-11-19T01:34:49 < KreAture_> something is wonky and I have no clue what, alignment? linker issues? stack/heap fubars ?

2014-11-19T01:35:27 < KreAture_> looking at my stack in the hard fault handler I see it jumps there from _start
2014-11-19T01:35:37 < KreAture_> so it's not directly related to freertos or my app I think
2014-11-19T01:35:42 < KreAture_> it happens while it sets up stuff
2014-11-19T01:36:27 < KreAture_> startup_stm32fxx.S seems to be the one doing the _start so I've been annoyed as a 0-g badger for half an hour now
2014-11-19T01:37:20 < KreAture_> using Em::Blocks IDE btw and the bare-metal compiler
2014-11-19T01:41:34 < _Sync_> dongs: that crash doesn't look too bad
2014-11-19T01:41:38 < dongs> KreAture_: sounds like stack to me
2014-11-19T01:41:53 < _Sync_> I'm acutally suprised that the car held up that well
2014-11-19T01:42:07 < KreAture_> increased and decreased it and it still happens
2014-11-19T01:42:23 < KreAture_> tried finding out what it does in the _start but it seems to crash the debugger
2014-11-19T01:43:05 < dongs> how about thread stack work area did you forget - 1 or something when passing size or so

2014-11-19T02:25:29 < zyp> that call looks fine, so just executing the call should not fault anything

2014-11-19T03:16:00 < qyx_> started code blogging and githubbing recently
2014-11-19T03:16:15 < qyx_> dongs: you were asking for something like that https://github.com/iqyx/lineedit
2014-11-19T03:16:36 < qyx_> although still not  sane and finished
2014-11-19T03:17:23 < KreAture_> unless I am reading the status wrong, you are right though, nocp seems to be the flag
2014-11-19T03:17:25 < KreAture_> really odd
2014-11-19T03:18:56 < zyp> yes, so it's either a coprocessor instruction or garbage data interpreted as a coprocessor instruction
2014-11-19T03:22:00 < KreAture_> hmm
2014-11-19T03:22:14 < KreAture_> could it be it trying a long call on a thump instruction set ?
2014-11-19T03:22:17 < KreAture_> thumn
2014-11-19T03:22:17 < dongs> qyx_: nice
2014-11-19T03:22:19 < zyp> no, I checked that
2014-11-19T03:22:20 < KreAture_> thumb
2014-11-19T03:22:28 < zyp> and that would give INVSTATE, it's a common problem
2014-11-19T03:22:35 < KreAture_> yeh
2014-11-19T03:22:39 < KreAture_> weird
2014-11-19T03:25:36 < KreAture_> and it is definately related to the positions of the sections or the size of the app as removing some unused audio codec I had here made the faulting code work
2014-11-19T03:25:52 < KreAture_> I removed some code that I was not using, initializing or in any way refering
2014-11-19T03:26:10 < KreAture_> it did make the final elf smaller

2014-11-19T16:05:03 < dongs> fuuuuuuuuuuuuuuuuuuuuuuck
2014-11-19T16:05:06 < dongs> timecube is garbage
2014-11-19T16:06:56 < akaWolf> dongs: you are doing it wrong
2014-11-19T16:07:09 < akaWolf> you need to say "fuuuuuuuu"
2014-11-19T16:07:12 < akaWolf> :)
2014-11-19T16:14:54 < decimad2> what's there to look out for this time?
2014-11-19T16:15:15 < dongs> its just garbage, all their examples are just insane
2014-11-19T16:15:22 < dongs> they make a whole new file for "MSP" (still dunno wat that is
2014-11-19T16:15:25 < dongs> and in there do shit like
2014-11-19T16:15:30 < dongs> HAL_TIM_PWM_MspInit
2014-11-19T16:15:40 < dongs> where they turn on clcoks/timer clock/configure gpio
2014-11-19T16:18:02 < Steffanx> i wonder if they will ever figure out timecube was a mistake.
2014-11-19T16:18:11 < akaWolf> and what is wrong with that function, dongie?
2014-11-19T16:18:22 < akaWolf> name or what?
2014-11-19T16:18:25 < dongs> everythign

2014-11-19T16:19:10 < Steffanx> more people left?

2014-11-19T16:19:34 < Steffanx> only the hardcore debian guys i guess?

2014-11-19T16:21:14 < Steffanx> Hah, get it somewhere in your kids/wifes bedroom (while you're not there) and make it beep randomly
2014-11-19T16:21:43 < dongs> Steffanx: thinkgeek or something sold something similar
2014-11-19T16:22:19 < dongs> im heading to tokyo maker failtomrorow, i'll just bring that wiht me and get on hackaday
2014-11-19T16:22:56 < Steffanx> Dump a few thousand of them everywhere and go viral.
2014-11-19T16:23:06 < dongs> ebola
2014-11-19T16:23:31 < Steffanx> Don't forget a rick-roll sound.
2014-11-19T16:23:37 < BrainDamage> dickstarter it, for 15$ you can have your own board, with already blinking code flashed in!
2014-11-19T16:23:38 < dongs> ill port the modplayer to it
2014-11-19T16:23:42 < BrainDamage> free hackaday pass
2014-11-19T16:23:56 < decimad2> the least problems of cubef4 is garbage code that you can leave unimplemented/uncalled I guess
2014-11-19T16:24:23 < dongs> the whole HAL shit is just annoying
2014-11-19T16:24:31 < dongs> 2-3 layers of indirection with no good reason
2014-11-19T16:25:01 < Taxman> dongs: I think the debian users should have the choice during installation if they prefer simpleinit, system-V init or this new systemd
2014-11-19T16:25:04 < decimad2> HAL_Init will call MspInit, which is weak and probably implemented empty? The user can then call Hal_PerphMspIninit or something if I understand it correctly
2014-11-19T16:25:44 < BrainDamage> meh, it's a gigantic work to support multiple init systems
2014-11-19T16:25:46 < decimad2> weak-Static-Polymorphism ;)
2014-11-19T16:26:00 < BrainDamage> you still have to pick up one, and make it official, if one wants, he can switch
2014-11-19T16:26:02 < dongs> decimad2: haha, i think you might be right
2014-11-19T16:26:12 < dongs> thats just insane
2014-11-19T16:26:35 < dongs> so when it does HAL_Tim_INit()
2014-11-19T16:26:41 < dongs> it'll call HAL_TIM_PWM_MspInit() for the same handle
2014-11-19T16:26:43 < dongs> to turn on clocks/shit
2014-11-19T16:26:59 < dongs> if it exists that is... so you gotta know the function sig and stuff.
2014-11-19T16:27:01 < dongs> man that is fucking trash.
2014-11-19T16:27:35 < akaWolf> dongs: I can't understand, you are against HAL as a principle?
2014-11-19T16:27:45 < akaWolf> in*
2014-11-19T16:27:47 < BrainDamage> if you want i can throw a stern note when i pass next to st's complex in agrate
2014-11-19T16:28:02 < dongs> akaWolf: im very against this moronic implementation, but in general I don't think MCUs need HAL
2014-11-19T16:28:14 < dongs> because really how fucking often do you start on a project on L0
2014-11-19T16:28:16 < dongs> then move to F1
2014-11-19T16:28:19 < dongs> then to F4
2014-11-19T16:28:20 < dongs> or wahtever
2014-11-19T16:28:22 < dongs> with same codebase
2014-11-19T16:28:28 < dongs> like:  never
2014-11-19T16:28:33 < decimad2> wouldnt you start with f4 and then go to f0?

2014-11-19T16:28:34 < akaWolf> dongs: it's not so
2014-11-19T16:28:41 < BrainDamage> you want hal only if you plan to keep changing micro, which is already a symptom of something wrong in the proejct development
2014-11-19T16:28:52 < BrainDamage> like constantly moving goalpost
2014-11-19T16:28:57 -!- emeb [~ericb@ip68-104-219-12.ph.ph.cox.net] has joined ##stm32
2014-11-19T16:29:02 < dongs> and hardware specific shit can be ported just as easily if needed, logic and other stuff should be decoupled enough from hw deps not to need a lot of changes when changing platform
2014-11-19T16:29:10 < BrainDamage> altough hal is niceish to have a quick prototype
2014-11-19T16:29:11 < dongs> BrainDamage: right, exactly
2014-11-19T16:29:14 < akaWolf> dongs: where I'm working now the same codebased successfully changed about 3 or 4 MCU's from even different platforms...
2014-11-19T16:29:32 < akaWolf> looks like you are never worked under good planed projects
2014-11-19T16:29:33 < akaWolf> at all
2014-11-19T16:29:43 < dongs> you mean "good" planned projects
2014-11-19T16:31:12 < akaWolf> if you look at Symbian eka2 kernel, you can find a strong HAL level, which give you a freedom in implementation: you can run Symbian even on Windows
2014-11-19T16:31:52 < dongs> akaWolf: i dont think hal belongs on mcu, unless its amazingly well written (and i haven't seen that yet)
2014-11-19T16:32:12 < akaWolf> I told you about a case in my own life
2014-11-19T16:32:25 < akaWolf> there is a project at Cortex-M4 now
2014-11-19T16:32:41 < akaWolf> which was at AtMega before
2014-11-19T16:32:43 < decimad2> i guess a hal to go betwen nxp and stm would have greater benefit than a hal to move between models of the same vendor...
2014-11-19T16:32:45 < dongs> so you mean your 3-4 mcu changed project has a hal that required no changes to run on all of htem>?
2014-11-19T16:33:08 < dongs> so can you go back from M4 project to atmea and run it (slowly)?
2014-11-19T16:33:41 < akaWolf> dongs: at leas, it' required a much less changes
2014-11-19T16:33:43 < akaWolf> t
2014-11-19T16:33:47 < akaWolf> s
2014-11-19T16:34:31 < akaWolf> then which the same project implemented without HAL

2014-11-19T16:38:43 < decimad2> It's just a customization point... much as virtuals in c++...
2014-11-19T16:39:45 < decimad2> and I can't stand that in C you need to include the context in every symbol... that just sucks
2014-11-19T16:40:00 < akaWolf> dongs: embedded software growing in size and complexity day by day
2014-11-19T16:40:13 < akaWolf> like and power of MCU's
2014-11-19T16:40:39 < dongs> akaWolf: im just an irc troll, so my most complex embeded project is while (1) { troll(); }
2014-11-19T16:40:45 < dongs> so hal is extra for me
2014-11-19T16:40:46 < dongs> gnite
2014-11-19T16:41:00 < BrainDamage> hal makes sense when you need portability, but with embedded you ship the programmed device, vs x86 you ship the binary
2014-11-19T16:41:05 -!- barthess [~barthess@37.17.112.255] has quit [Ping timeout: 272 seconds]
2014-11-19T16:41:09 < akaWolf> so there is nothing strange, that HAL came from a big PC-oriented to MCU
2014-11-19T16:41:25 < akaWolf> systems
2014-11-19T16:41:45 < BrainDamage> so skipping the hal since your target platform is one and one makes perfect sense
2014-11-19T16:42:07 < BrainDamage> ofc if one gives you for free a decent hal, one can consider for mcu too
2014-11-19T16:42:08 < decimad2> it's only bad for newbies like me, that need to blend the hal layer out when parsing stuff
2014-11-19T16:42:28 < BrainDamage> but as usual, i'm still waiting for that free lunch
2014-11-19T16:42:32 < akaWolf> not when you are want to elaborar your device.
2014-11-19T16:42:46 < BrainDamage> sorry?
2014-11-19T16:43:10 < akaWolf> sorry, it's spanish
2014-11-19T16:43:28 < akaWolf> elaborate*
2014-11-19T16:43:38 < BrainDamage> still not clearer, do you mean upgrade?
2014-11-19T16:43:42 < akaWolf> yeah
2014-11-19T16:43:51 < akaWolf> making a new versions
2014-11-19T16:43:59 < akaWolf> with a new functions
2014-11-19T16:44:09 < akaWolf> at least for 5 years
2014-11-19T16:44:15 < akaWolf> in series
2014-11-19T16:44:17 < BrainDamage> how often does that happen? typically with new devices the capabilities change radically, not to mention the pinout that requires a pcb re-routing
2014-11-19T16:44:20 < decimad2> don't you end up with your own libraries, interfaces etc. for the problem domain anyways?
2014-11-19T16:44:30 < akaWolf> ofcouse
2014-11-19T16:44:46 < akaWolf> I'm told you about long-termed project
2014-11-19T16:44:58 < decimad2> I don't have the feeling that the mcus come any way near the complexity of desktop stuff
2014-11-19T16:45:33 < BrainDamage> well, it's sorta halfway between
2014-11-19T16:46:05 < BrainDamage> stm32 are one mmu short of linux for instance
2014-11-19T16:46:49 < decimad2> What I mean is, the OS adds a whole level of complexity. And problems handles on desktop are more complex in themselves.
2014-11-19T16:47:02 < BrainDamage> altough generally an mcu is chosen over a more mundane processor because it's more self contained and cost effective
2014-11-19T16:47:36 < BrainDamage> adding layers of indirection is actually working against that principle
2014-11-19T16:48:16 < BrainDamage> you might as well buy a cheap arm board and use directly a full fledged os, perhaps stripped down of userspace junk
2014-11-19T16:48:56 < decimad2> makes reasoning about correctness and safety and all harder I guess
2014-11-19T16:49:30 < BrainDamage> yes, not "nuclear reactor control loop" safe for sure
2014-11-19T16:50:15 < decimad2> also what's the reason to do that if it doesn't really make things simpler, since "installing new apps" is probably not what a motor controller is intended for...
2014-11-19T16:50:58 < karlp> decimad2: re "I can't stand including the context" so object.doThing() is ok, but doThing(object) is not ok?
2014-11-19T16:51:03 < BrainDamage> well, there's plenty of applications where the development time / costs justify using totally unoptimized because developer time is more worthy than consmer
2014-11-19T16:51:50 < BrainDamage> especially low volume stuff
2014-11-19T16:51:59 < decimad2> karlp: what I mean was stuff like   STM_HAL_FOO_XYZ_FOFOFO_Init( FOFO_AHAHA_FSDSDS_ASAAA_Handle_TypeDef* );
2014-11-19T16:52:43 < karlp> so, the name then?
2014-11-19T16:53:19 < decimad2> Yeah, it's just a readability thing. I prefer namespaces for that... you can rearrange them, import symbols etc.
2014-11-19T16:54:30 < karlp> right, so it's not "including the  contexxt" like you claimed the first time :)
2014-11-19T16:54:57 < decimad2> well the context is that this Init relates to the FOFO_AHAHAHA_FSDSDSDS context
2014-11-19T16:56:43 < decimad2> Maybe we can settle on better wording... but I take the initial parts of the symbol as "context". I would prefer a.doThing() over doThing(a) only, if the implicit "this" is a reasonable match for what goes on.
2014-11-19T16:58:05 < decimad2> And it's a totally unrelated question to what I meant by context.
2014-11-19T16:59:36 < karlp> or, to rephase, C is for stinky losers, c++ is better, end of story? ;)
2014-11-19T16:59:58 < zyp> are you still going on about that?
2014-11-19T17:00:27 < decimad2> many people use it and don't complain, so it's no problem, it seems
2014-11-19T17:01:48 < karlp> I'm mostly just poking decimad :)
2014-11-19T17:02:20 < zyp> as for the x.foo() vs bar(x), the argument is easy
2014-11-19T17:02:28 < decimad2> though I wonder why it wasnt adapted, since context and grammar updates to language don't move you further from hardware... all languages invented afterwards seem to bring that stuff, why do they go to that effort?
2014-11-19T17:02:50 < zyp> foo is in the class' namespace and can't collide with similarly named functions in other classes, bar can and thus needs a more verbose name
2014-11-19T17:03:15 < englishman> where are the timecube docs anyway? the ones like the old stdlib .chf with all the functions etc

2014-11-19T17:39:10 < decimad_> So what is it about about that systemd war? Does systemd actually improve anything or provide features that are otherwise not technically possible?
2014-11-19T17:43:01 < karlp> it's not a war.
2014-11-19T17:43:11 < karlp> it's old people going, "init scripts or gtfo"
2014-11-19T17:43:35 < madist> i haven't seen anyone make a clear case why systemd is better
2014-11-19T17:43:39 < karlp> and of course a few people who are against it solely because of who wrote it.
2014-11-19T17:43:42 < madist> they just say init scripts are crufty
2014-11-19T17:43:49 < karlp> better than what? better than init scripts, or better than upstart?
2014-11-19T17:43:56  * tkoskine is one of those old people. :)
2014-11-19T17:44:04 < madist> better than anything. pick init scripts its easier.
2014-11-19T17:44:13 < karlp> it's way faster to startup, and way easier to manage dependencies between processes
2014-11-19T17:44:21 < karlp> which is also true of upstart
2014-11-19T17:45:04 < karlp> compare init scripts that keep suse happy, vs redhat, vs solaris, vs debian, all different, but still all "init scripts are the one true way"
2014-11-19T17:45:17 < synic> this will give you an idea: http://0pointer.net/blog/revisiting-how-we-put-together-linux-systems.html
2014-11-19T17:45:33 < karlp> I actuallythought upstart was easier to use and is certainyl far better documented, but systemd seems to have won that bit.
2014-11-19T17:45:41 < synic> its almost like they want to use systemd to fix *everything*
2014-11-19T17:45:46 < synic> which pisses a bunch of people off
2014-11-19T17:46:11 < karlp> instead of "with enough /bin/sh I can fix anything already" :)
2014-11-19T17:46:17 < synic> because it will cause systems like gnome and kde to depend on systemd, making distros like slackware who don't want to use systemd have to patch their systems
2014-11-19T17:46:52 < decimad_> this shouts for an IAL!
2014-11-19T17:46:53 < synic> pretty sure I said system too many times there.  it's early
2014-11-19T17:48:25 < decimad_> So systemd is faster and arguably simpler (though you tend to trap into problems with "ide") to configure, but comes with strong coupling?
2014-11-19T17:48:43 < tkoskine> synic: *BSDs have same problem. It is hard to use GNOME, KDE, etc. on any BSD system if they depend on systemd. (So, the real problem isn't actually systemd, but all other software which wants to create hardcoded dependency to systemd.)
2014-11-19T17:49:25 < synic> decimad_: I don't know about all the stuff you said at the beginning, but the part at the end is true
2014-11-19T17:50:57 < decimad_> tkoskine: Well, if there's an organizing black box identity between you and the system (much like an ide is between your source and the linker), you seemingly often run into walls, that's what I meant.
2014-11-19T17:51:31 < decimad_> synic even, sorry
2014-11-19T17:55:28 < decimad_> well, I hope they will settle on some consensus... threatening with forks doesn't sound good though

2014-11-19T18:16:07 < KreAture_> I am getting a hardfault that seems dependant on layout/size of code
2014-11-19T18:16:36 < KreAture_> I thought I had plenty of stack and heap but it could very well be a problem
2014-11-19T18:17:23 < decimad_> does it happen immediately?
2014-11-19T18:19:23 < KreAture_> It happens on start of my app now
2014-11-19T18:19:34 < KreAture_> it used to happen in the call to __gcc_init_array
2014-11-19T18:19:39 < KreAture_> as in, when doing the hop
2014-11-19T18:20:09 < KreAture_> I did notice something though, when it failed on the hop it needed two asm-steps in debugger to get to the faulthandler
2014-11-19T18:20:22 < KreAture_> when it does not happen it needs 1 step to get to the function it is calling
2014-11-19T18:20:50 < KreAture_> now that I added a different faulthandler that saves PC etc I can see where it happens and add break there
2014-11-19T18:20:56 < KreAture_> then singlestep and see it happen
2014-11-19T18:22:14 < KreAture_> right now it happens in prvPortStartFirstTask

2014-11-19T19:10:38 < TheSeven> hm...
2014-11-19T19:10:54 < TheSeven> I just managed to break an F030 chip in an odd way
2014-11-19T19:11:16 < TheSeven> I suspect that the SWD debug signals were briefly shorted to each other, vcc or ground
2014-11-19T19:11:45 < TheSeven> the result was a chip that couldn't be discovered via swd (openocd: target init failed)
2014-11-19T19:12:02 < TheSeven> however it popped back to life when I pulled up BOOT0... weird
2014-11-19T19:12:53 < TheSeven> it behaved a bit as if the chip was in a low power mode otherwise, but that firmware image doesn't use low power modes at all, so I don't think a partially flashed firmware could have easily caused this
2014-11-19T19:15:54 < jpa-> TheSeven: partially flashed firmware can cause the code to end up in lockup
2014-11-19T19:16:14 < TheSeven> yeah but openocd should be able to connect to that
2014-11-19T19:16:16 < jpa-> but if you are using stlink v2 and some magic openocd switches, it should use nrst when connecting and not mind that
2014-11-19T19:16:40 < TheSeven> openocd didn't mind the "nothing flashed to this device at all" lockup at least
2014-11-19T19:16:49 < jpa-> but i'm never sure when my openocd commands are right or not :)
2014-11-19T19:17:03 < jpa-> well that is an easier case.. even stlinkv1 can get out of that
2014-11-19T19:17:28 < TheSeven> how much worse than that could a partially flashed (trivial) firmware even be?
2014-11-19T19:17:45 < jpa-> not sure if it can
2014-11-19T19:18:16 < TheSeven> note to self: pull up on MISO helps if SD cards fail to initialize ;)
2014-11-19T19:18:25 < jpa-> i guess lockup should still allow swd..
2014-11-19T19:18:59 < jpa-> but it doesn't allow code execution, which causes trouble for swd prommers that don't know how to software reset
2014-11-19T19:19:46 < jpa-> i've also seen floating boot0 cause interesting stuff :P
2014-11-19T19:20:34 < TheSeven> well it will cause IRQs to go to the system memory vector table addresses, which isn't likely what you want ;)
2014-11-19T19:20:57 < TheSeven> (unless your code takes care of it by setting the remap bits accordingly)
2014-11-19T19:21:02 < TheSeven> speaking of which... (but I guess I should discuss that on #openocd) ...is it easily possible to teach openocd to flash external memory, e.g. spi flash?
2014-11-19T19:23:39 < Steffanx> It's not that the standard kind of requires you to add pullups TheSeven ..
2014-11-19T19:23:52 < TheSeven> sure ;)
2014-11-19T19:24:19 < TheSeven> just something that is easily missed when porting something and thinking "damn, that driver used to work before" ;)
2014-11-19T19:24:31 < TheSeven> this was more of a facepalm incident ;)

2014-11-19T20:37:51 < PaulFertser> easy and logical ;)
2014-11-19T20:38:50 < PaulFertser> TheSeven: flashing SPI flash depends on how you have it connected. For some LPC parts that have special controller it's already implemented.
2014-11-19T20:39:28 < PaulFertser> TheSeven: but if you're talking about a flash chip connected to SPI of STM32, then you'd have to write an stm32-specific flash loader. It isn't really hard.
2014-11-19T20:39:52 < TheSeven> yeah I'm wondering how to plug such a loader (for arbitrary memory) into openocd
2014-11-19T20:40:00 < TheSeven> are there any docs/tutorials on that?
2014-11-19T20:41:56 < PaulFertser> TheSeven: no docs, but existing code is easy to understand, plus I can explain if anything's unclear. I wrote mdr.c driver and loader, so have some experience.

2014-11-19T20:42:50 < TheSeven> does it require recompiling openocd or can it be plugged in by means of a config file + loader binary?
2014-11-19T20:42:51 < PaulFertser> TheSeven: I do not think any other system supports lockless ringbuffer for loading, I guess Keil is writing block-by-block with explicit synchronisation between the target and debugger after each one.

2014-11-19T20:43:42 < PaulFertser> karlp: well, imho it makes plenty of sense once you understand it once by reading the Info manual.

2014-11-19T20:43:59 < PaulFertser> TheSeven: OpenOCD is easy to cross-compile for windows using a saner OS.
2014-11-19T20:44:00 < TheSeven> and I just can't get that particular application for this loader to use linux ;)
2014-11-19T20:44:57 < TheSeven> the only one that doesn't quite make sense to me (without looking at the manual) is srst_nogate
2014-11-19T20:45:38 < karlp> and that you need all of them.
2014-11-19T20:46:29 < Laurenceb> should it be possible to view a tcxo output with a scope?
2014-11-19T20:46:38 < Laurenceb> or will it be too heavily loaded?
2014-11-19T20:47:30 < PaulFertser> TheSeven: some targets can't talk to a debugger under reset, and OpenOCD prefers to know about that to avoid problems. So in fact an upstream target config should specify srst_nogate option whenever the target is nicely implementing it, so you only have to add the missing "srst_only" (if you actually have srst connected, openocd can't autodetect it) and "connect_assert_srst" (if you want to
2014-11-19T20:47:36 < PaulFertser> connect this way, which is not always nice when you want to inspect a target without resetting it).

2014-11-19T21:10:39 < Tectu_> looks like porn really doesn't imply sex

2014-11-19T21:47:31 < decimad> big [end] first is easier to comprehend than big end [first] imho
2014-11-19T21:47:42 < GargantuaSauce> it's a mnemonic, not the real etymology
2014-11-19T21:47:59 < decimad> I cannot even find "endian" as a word :(
2014-11-19T21:47:59 < GargantuaSauce> seems to me the term actually comes from gulliver's travels

2014-11-19T22:25:23 < Steffanx> How's airplaning?
2014-11-19T22:26:03 < zyp> only waterplaning nowadays
2014-11-19T22:26:07 < brabo> well, i am pretty new to this, my networking didnt seem to work, and theseven asked me to check the tx desc own bit, that one was properly reset during init, now i am scoping on the cat5 cabe and it seems it sends out a dhcp request, and it seems it is getting an answer, however, the software doesn't get anything.. so then i was thinking, let's check the rx own bit, and it seems it is still set
2014-11-19T22:27:38 < brabo> the eth desc init (from libopencm3) does set the tx desc own bit during init, and that gets reset (by the hardware i presume), the rx desc own bit is not set there
2014-11-19T22:28:39 < brabo> hence my thinking perhaps i need to do smething there ;)
2014-11-19T22:28:55 < gxti> rx own bit should be set on all your descriptors by the end of your init function, because that's what tells the DMA it's ok to start receiving data
2014-11-19T22:29:08 < gxti> tx own bit should not be set until you are ready to transmit a frame
2014-11-19T22:29:10 < brabo> aha
2014-11-19T22:29:22 < gxti> 'OWN' means the DMA owns that descriptor until it feels like giving it back to you
2014-11-19T22:29:40 < gxti> if DMA owns a tx desc, then it's going to transmit it then clear the bit to give it back to you
2014-11-19T22:29:52 < gxti> if dma owns a rx desc, then it's going to scribble a new frame there when it arrives then clear the bit
2014-11-19T22:29:56 < brabo> mmm well, is it okay if i pastebin the libopencm3 the desc init? i am not really sure where i'd need to do what exactly

2014-11-19T22:31:12 < decimad> did you set ETH_DMAOMR bit 1?
2014-11-19T22:31:18 < brabo> gxti: https://github.com/libopencm3/libopencm3/blob/master/lib/ethernet/mac_stm32fxx7.c starting at line 67 eth_desc_init
2014-11-19T22:31:34 < brabo> decimad: god question, need to check it
2014-11-19T22:32:40 < gxti> ST and SR are set in eth_start
2014-11-19T22:33:04 < gxti> which you call last, i guess.

2014-11-19T22:34:33 < brabo> decimad: ETH_DMAOMR |= ETH_DMAOMR_SR;  so ye, that gets set
2014-11-19T22:34:48 < gxti> brabo: and you're doing that after eth_desc_init right?
2014-11-19T22:35:13 < brabo> gxti: yes, in eth_start this gets set, and that is after eth_desc_init

2014-11-19T22:37:26 < brabo> *think
2014-11-19T22:41:12 < brabo> so uhm gxti i should set the rx own yes? like: ETH_DES0(bd) = ETH_TDES0_OWN; or?
2014-11-19T22:41:40 < gxti> eth_desc_init already is
2014-11-19T22:42:03 < brabo> i only see ETH_RDES0_OWN being set

2014-11-19T22:42:14 < gxti> TDES is for transmit descriptors, RDES is for receive descriptors
2014-11-19T22:42:30 < brabo> oh crap
2014-11-19T22:42:34 < brabo> brainfart :p
2014-11-19T22:42:43 < gxti> it's actually the same value for that particular case.
2014-11-19T22:43:04 < brabo> uh okay, so wait, the tx is not being set, and that works..
2014-11-19T22:43:20 < gxti> you don't set it on tx until you have a frame to send
2014-11-19T22:43:28 < brabo> ah okay
2014-11-19T22:43:37 < gxti> e.g. in eth_tx
2014-11-19T22:43:42 < brabo> okay
2014-11-19T22:43:50 < brabo> ah ye
2014-11-19T22:43:53 < brabo> i see
2014-11-19T22:44:38 < gxti> you copy your contents into the buffer, then set OWN to give DMA permission to use it, then finally you kick the DMA engine by writing DMATPDR
2014-11-19T22:45:08 < gxti> for receive though obviously the process is initiated externally by a packet coming in on t he wire, so you give all your buffers upfront and then get an interrupt each time a frame arrives
2014-11-19T22:47:08 < brabo> gxti: so more precise, this fails: while (!(ETH_DES0(RxBD) & ETH_RDES0_OWN) && !ls) {   in eth_rx.. i also tried ressetting the own bit maunally, but that did not work
2014-11-19T22:48:23 < brabo> well
2014-11-19T22:48:45 < brabo> it doesnt fail when i reset own, but it goes through the loop without getting anything
2014-11-19T22:48:58 < gxti> you should never clear the own bit yourself
2014-11-19T22:49:49 < brabo> i figured, but i also figured i wouldn't brak anything with tryxing
2014-11-19T22:50:27 < brabo> so okay, the hardware should reset this, but it isnt being done?
2014-11-19T22:50:43 < zyp> I'm not sure if this will help you, but here's a real simple receive-only piece of code I wrote once: http://cgit.jvnv.net/laks_demo/tree/main.cpp?h=ethernet
2014-11-19T22:51:30 < gxti> brabo: when are you calling eth_rx? interrupt? periodically?

2014-11-19T23:54:31 < brabo> i see tx happening, picotcp's dhcp should be sendiong out, i can't see that on tcpdump, but i noticed that very shortly afetr the tx signal the router sends some dhcp ack
2014-11-19T23:54:35 < ds2> (quick and dirty way of sorting out PHY/RMII/SoC)
2014-11-19T23:54:55 < ds2> the router might be filtering
2014-11-19T23:55:01 < brabo> i see the rx wiggle at thjat same time
2014-11-19T23:55:07 < ds2> a simple debugging setup is helpful -
2014-11-19T23:55:20 < ds2> [DUT] - *HUB* - Laptop
2014-11-19T23:55:27 < brabo> so i assume the dhcp request gets sent and the router replies to that
2014-11-19T23:56:00 < brabo> yea i do not have a good setup yet.. only starting out :)

2014-11-20T00:04:51  * TheSeven still has a 3com 8 port 100mbit/s hub around somewhere
2014-11-20T00:05:08 < TheSeven> that thing needed an awful amount of power and got really hot
2014-11-20T00:05:27 < Taxman> with an external power supply?
2014-11-20T00:05:47 < TheSeven> yes
2014-11-20T00:05:56 < TheSeven> some brick style thing almost as big as the hub ;)
2014-11-20T00:05:56 < Taxman> thats good

2014-11-20T00:59:25 < ds2> brado: yeah
2014-11-20T00:59:45 < ds2> brado: well, maybe... a xover cable is safer.... automdx is not guaranteed on anything but GigE
2014-11-20T00:59:47 < TheSeven> basically anything manufactured in the last 10 years can do auto-mdix
2014-11-20T01:00:17 < ds2> strictly speaking, automdx is only in the GigE standard
2014-11-20T01:00:34 < TheSeven> and even if the other device can't do it, the device that he's testing should do it
2014-11-20T01:00:53 < ds2> when testing, one should not relying on "should behave"
2014-11-20T01:01:09 < karlp> 10meg vs 100meg autoneg fails a lot in the past too
2014-11-20T01:01:24 < ds2> that's fine to rely on if you are in IT but when you are in embedded, it is best to do things step by step
2014-11-20T01:01:31 < TheSeven> yeah, but if that is a problem, it's really obvious what is going on and that the phy config needs fixing (you wouldn't even get link up in the first place)
2014-11-20T01:01:53 < ds2> does the STM32 do MDIO?

2014-11-20T01:02:00 < TheSeven> yes
2014-11-20T01:02:21 < ds2> I suppose you can ask the phy if it things life is good using MDIO
2014-11-20T01:02:41 < ds2> link up is a strange beast... I gotten one end to show link and the other end to not
2014-11-20T01:02:41 < TheSeven> yes, and IIUC brabo is already doing that and getting "link up"
2014-11-20T01:02:59 < brabo> return eth_smi_read(1, PHY_REG_CR1) & 0x07;
2014-11-20T01:03:14 < ds2> donno the phy...IIRC, some phys can provide link status as a line (i.e. the LED outputs)
2014-11-20T01:03:20 < brabo> that is returning the link status in the ethernet phy source file
2014-11-20T01:03:46 < brabo> i print it out, it says 100M full duplex
2014-11-20T01:04:03 < ds2> becareful with FD
2014-11-20T01:05:02 < brabo> well i can try to force no FD
2014-11-20T01:06:37 < qyx_> why should be FD bad?
2014-11-20T01:06:57 < qyx_> also
2014-11-20T01:08:08 < ds2> cuz some equipment don't handle FD well
2014-11-20T01:08:23 < qyx_> never seen such

2014-11-20T01:31:05 < brabo> mmm ye, at like 10-HD still nada
2014-11-20T01:31:52 < brabo> isn't it weird btw that tcpdump sees nothing, but the scopde does from time to time?
2014-11-20T01:32:34 < TheSeven> brabo: are you looking on the cable or MII side?
2014-11-20T01:32:41 < brabo> cable
2014-11-20T01:32:48 < TheSeven> on the cable side you'll see link alive / negotiation bursts
2014-11-20T01:32:53 < brabo> aha
2014-11-20T01:33:00 < TheSeven> those are issued by the phy
2014-11-20T01:33:12 < brabo> okay
2014-11-20T01:33:19 < TheSeven> you need to look at that TX_EN and CRS_DV line
2014-11-20T01:33:30 < ds2> verify the RGMII side
2014-11-20T01:33:34 < brabo> okay
2014-11-20T01:33:36 < TheSeven> those indicate data communication between the MAC and PHY
2014-11-20T01:33:42 < brabo> can do that through the gpio header pins right?
2014-11-20T01:33:49 < TheSeven> no idea what your board looks like
2014-11-20T01:34:00 < TheSeven> just check what that line is connected to
2014-11-20T01:34:04 < ds2> isn't there also a clock?
2014-11-20T01:34:04 < TheSeven> and grab it anywhere
2014-11-20T01:34:20 < TheSeven> sure, there's a clock as well, but who cares about that one?
2014-11-20T01:34:34 < TheSeven> if it wouldn't be running, he couldn't even initialize the MAC (it would lock up during soft reset)
2014-11-20T01:35:03 < ds2> no, the RMII clock
2014-11-20T01:35:10 < TheSeven> yes, I mean that
2014-11-20T01:35:29 < TheSeven> the MAC will lock up if the RMII clock isn't running
2014-11-20T01:35:32 < ds2> i found it worthwhile checking the rate of the clock to see if it a  sane value for the link speed
2014-11-20T01:36:10 < ds2> is that a STM thing or RMII thing? RGMII will happying run even if the clock is way off
2014-11-20T01:36:25 < ds2> RGMII on TI Sitara that is
2014-11-20T01:36:53 < TheSeven> ds2: I'm not talking about clock accuracy, but if the clock isn't running at all, we would have noticed by now
2014-11-20T01:37:16 < TheSeven> and as the hardware works with different firmware (he did say that earlier), I think we can rule out an inaccurate clock as well
2014-11-20T01:37:32 < TheSeven> my guess is that the DMA happily eats TX data but TX_EN never goes high
2014-11-20T01:37:48 < TheSeven> which is likely a GPIO config / AFIO pinmux problem, and those are really nasty on F107
2014-11-20T01:38:29 < ds2> 'k
2014-11-20T01:38:30 < qyx_> yep, i have spent few hours getting that to work on F107 in the past
2014-11-20T01:38:57  * TheSeven spent days hunting down a non-required clock gate being turned out, causing a similar problem
2014-11-20T01:39:05 < ds2> I spent days on a problem which turned out to be the clock tree not programmed right (TX Clock was at 25MHz when it should be 125MHz)
2014-11-20T01:39:45 < TheSeven> hm, is the RMII clock generated by the STM32 on that board?
2014-11-20T01:39:59 < TheSeven> in that case it could be an issue... I guess it's generated by the phy or an external oscillator though
2014-11-20T01:40:29 < TheSeven> also the RMII clock is independent of the link speed
2014-11-20T01:40:56 < ds2> hmm?
2014-11-20T01:41:04 < ds2> that doesn't SEEM to make sense
2014-11-20T01:41:08  * ds2 looks
2014-11-20T01:41:11 < TheSeven> it's just a common input clock to both the mac and the phy, usually produced by a dumb 50MHz xtal oscillator
2014-11-20T01:41:22 < TheSeven> which is sometimes integrated into the phy for BOM reasons
2014-11-20T01:41:58 < TheSeven> IIUC the MAC and PHY will internally divide that by 10 for 10mbit/s signalling
2014-11-20T01:41:59 < ds2> TXCLK Transmit clock, 25 MHz for 100Mbit/s, 2.5 MHz for 10Mbit/s. All Tx signals are referenced to this clock (PHY to MAC)
2014-11-20T01:42:06 < ds2> that's from wikipedia if you trust that
2014-11-20T01:42:10 < TheSeven> ds2: that's MII, not RMII
2014-11-20T01:43:11 < ds2> ah
2014-11-20T01:43:21 < ds2> different trick then RGMII, my bad
2014-11-20T01:43:52 < TheSeven> yeah it's quite a mess with all those different standards ;)
2014-11-20T01:43:54 < ds2> 'k then that can't be relevant
2014-11-20T01:44:12 < TheSeven> ...unless it's generated by the STM32's MCO and off by some some amount
2014-11-20T01:44:31 < TheSeven> but I guess he won't even see TX_EN pulses, which would mean that something else must be wrong
2014-11-20T01:44:41 < ds2> *nod*
2014-11-20T01:45:08 < ds2> hmmmm this is slow enough to plop on a LA
2014-11-20T01:45:35 < TheSeven> yes, or to just make a scope trigger on it while repeatedly sending packets
2014-11-20T01:45:49 < ds2> ping -f ;)
2014-11-20T01:46:07 < TheSeven> preferably the other direction ;)
2014-11-20T01:46:24 < TheSeven> I don't think we have even looked at RX yet
2014-11-20T01:50:28 < ds2> used to having ping -f available on the TX direction
2014-11-20T01:50:40 < ds2> just be sure to use broadcasts
2014-11-20T01:50:51 < ds2> cuz w/o a known working RX, ARP will fail
2014-11-20T01:51:19 < TheSeven> I'd probably just hand junk data to the TX DMA without even messing with an IP stack ;)
2014-11-20T01:54:03 < ds2> is the chip smart enough to generate the preamble or does sw need to do that?
2014-11-20T01:55:32 < TheSeven> it even generates TCP checksums and decodes VLAN tags if you tell it to ;)
2014-11-20T01:56:27 < brabo> hm tomorrow morer

2014-11-20T02:20:57 < kakeman> hey I used download.com or such link from google
2014-11-20T02:21:57 < brabo> TheSeven: reading the backlog atm from just before, yes, the hardware does work, but, the demo formware runs in MII mode, there are a couple of jumpers to be set to turn it into rmii mode, but those are set correctly, i verified several times with the boards datasheet
2014-11-20T02:22:58 < TheSeven> oh!
2014-11-20T02:23:08 < brabo> the clock settings seem to be straightforward, but experience had taught me already that wrong clock settings do count for a big part of failures
2014-11-20T02:23:22 < TheSeven> that brings the clock back into the game indeed?
2014-11-20T02:23:26 < TheSeven> where does it come from in RMII mode?
2014-11-20T02:23:30 < brabo> i can pastebin what i am doing tho
2014-11-20T02:23:32 < TheSeven> this smells like MCO ;)
2014-11-20T02:23:53 < brabo> i do this:
2014-11-20T02:23:53 < brabo>     rcc_set_pll3_multiplication_factor(RCC_CFGR_PLLMUL_PLL_CLK_MUL10); rcc_osc_on(PLL3); rcc_wait_for_osc_ready(PLL3);
2014-11-20T02:23:56 < TheSeven> and IIRC the clock coming out of f2/f4 series MCO has too much jitter to work reliably for RMII
2014-11-20T02:23:57 < brabo>     rcc_set_mco(RCC_CFGR_MCO_PLL3);
2014-11-20T02:23:59 < TheSeven> f1 might be better though
2014-11-20T02:24:15 < brabo> ah cool, it's the f107 i am working with

2014-11-20T02:25:56 < brabo> lemme get the clock diagram, sec
2014-11-20T02:26:10 < TheSeven> 250MHz would seem excessive ;)
2014-11-20T02:26:28 < TheSeven> so there must be a prescaler somewhere

2014-11-20T02:30:42 < TheSeven> that's an area that would definitely deserve a closer look ;)
2014-11-20T02:30:49 < brabo> that function sets pll2:

2014-11-20T02:41:02 < KreAture_> flash
2014-11-20T02:41:05 < KreAture_> is memory too
2014-11-20T02:41:12 < brabo> huh going from the code in that libopencm3 rcc function.. pll2 is the clock source for pll1?`
2014-11-20T02:41:21 < qyx_> so how can local variables modify your code position?
2014-11-20T02:42:47 < KreAture_> qyx_ because the local vars dereference pointers to the ufsr, bfsr and mmfsr registers
2014-11-20T02:42:54 < KreAture_> volatile uint16_t ufsr = *((uint16_t *)0xE000ED2A);
2014-11-20T02:42:54 < KreAture_> volatile uint8_t bfsr = *((uint8_t *)0xE000ED29);
2014-11-20T02:42:54 < KreAture_> volatile uint8_t mmfsr = *((uint8_t *)0xE000ED28);
2014-11-20T02:43:19 < KreAture_> It's a easy to way to get the local vars updated so my autowatch can see em when I enter the hardfaulty
2014-11-20T02:43:24 < TheSeven> brabo: yes, I think that's the only valid setup that allows USB to work (or generally a speed of 72MHz) with a 25MHz xtal
2014-11-20T02:43:29 < KreAture_> saves me from having to type each time to find em etc
2014-11-20T02:44:05 < brabo> TheSeven: hse -> prediv2 (5) -> pll3mul -> mco = 25/5*10 = 50
2014-11-20T02:44:23 < KreAture_> The fact that my stipped down code works but only with those 3 lines added to my faulthandler is another nail in the coffin
2014-11-20T02:44:35 < KreAture_> without em I get hardfault every time
2014-11-20T02:44:38 < TheSeven> brabo: seems correct then, can't hurt to measure it though
2014-11-20T02:45:03 < KreAture_> It's almost as if the compiler is using wrong jumps or something causing it to fail, but it isn't according to asm
2014-11-20T02:45:10 < KreAture_> atleast I don't think it is
2014-11-20T02:45:39 < qyx_> have you really checked that those three lines shifts your code in .text?
2014-11-20T02:45:44 < KreAture_> yes
2014-11-20T02:45:47 < brabo> TheSeven: okay, tomorrow we measure that out as well
2014-11-20T02:46:21 < KreAture_> just as the other extra init shifted em in these elfs yesterday: http://kreature.org/projects/stm32/
2014-11-20T02:46:44 < KreAture_> One of those elfs work, other hardfaults just from 4 extra bytes in .text
2014-11-20T02:47:02 < KreAture_> I am really at a loss as to what causes this
2014-11-20T02:47:11 < KreAture_> My setup isn't that complicated
2014-11-20T02:47:39 < qyx_> alignment issue?
2014-11-20T02:47:50 < KreAture_> maby
2014-11-20T02:47:58 < qyx_> at least you can find out empirically
2014-11-20T02:48:03 < KreAture_> I am running 4k stack and 4k heap
2014-11-20T02:48:08 < KreAture_> just to be safe
2014-11-20T02:48:13 < KreAture_> My app needs almost no mem
2014-11-20T02:48:40 < qyx_> do you use any global initialized variables?
2014-11-20T02:48:56 < KreAture_> a few
2014-11-20T02:48:58 < KreAture_> bin\Debug\MERC.map|1|Program size (bytes):   10664|
2014-11-20T02:49:04 < KreAture_> ||Data size    (bytes):     404|
2014-11-20T02:49:09 < KreAture_> ||BSS size     (bytes):    4323|
2014-11-20T02:49:13 < KreAture_> ||Total size   (bytes):   15391   (R/W Memory: 4727)|
2014-11-20T02:49:20 < KreAture_> as you can see, it's pitiful
2014-11-20T02:49:29 < KreAture_> for a stm32f407 it's a laugh
2014-11-20T02:49:33 < qyx_> are they initialized correctly?
2014-11-20T02:49:46 < KreAture_> It is calling init
2014-11-20T02:49:50 < KreAture_> lemme have a look at em
2014-11-20T02:50:22 < qyx_> i mean initialized using c initializers
2014-11-20T02:50:58 < qyx_> those 404 bytes
2014-11-20T02:51:08 < TheSeven> well where exactly does it fault?
2014-11-20T02:51:21 < qyx_> do you rely on their initial value to be set?
2014-11-20T02:51:41 < qyx_> a if yes, is it set correctly? bad linker script can cause issues with that
2014-11-20T02:52:08 < qyx_> source data for them are placed usually at the end of .text section
2014-11-20T02:52:12 < KreAture_> TheSeven it just faults at odd places that shouldn't fault
2014-11-20T02:52:19 < KreAture_> like simple branches etc
2014-11-20T02:52:34 < KreAture_> qyx_ it never executes any of my code in the elfs I posted
2014-11-20T02:52:40 < TheSeven> KreAture_: always the same place (for the same binary), or randomly jumping around?
2014-11-20T02:52:46 < KreAture_> it fails in the call to __gcc_init_aray
2014-11-20T02:52:51 -!- Viper168_ is now known as Viper168
2014-11-20T02:52:55 < KreAture_> add some code and it fails in a new spot
2014-11-20T02:52:58 < KreAture_> or maby not fail
2014-11-20T02:53:03 < KreAture_> not seen a pattern yet
2014-11-20T02:53:15 < KreAture_> The two elfs I linked to are a good example
2014-11-20T02:53:20 < TheSeven> but the failing spot isn't moving for a single binary?
2014-11-20T02:53:33 < KreAture_> just simple gpio blinking and it fails and not fails with 4 bytes extra in text
2014-11-20T02:53:53 < KreAture_> no it always fails on same spot
2014-11-20T02:53:59 < KreAture_> untill I change code
2014-11-20T02:54:09 < KreAture_> deterministic
2014-11-20T02:54:09 < TheSeven> pick some binary that fails, and don't modify it. figure out where it fails, and try to add a breakpoint immediately before the failing instruction, then step one instruction to check if it actually fails
2014-11-20T02:54:09 < qyx_> try offseting the code continuously by 1 byte
2014-11-20T02:54:16 < KreAture_> I did
2014-11-20T02:54:20 < KreAture_> I did asm steps
2014-11-20T02:54:33 < TheSeven> so what is the failing instruction, and what's in the registers that it uses?
2014-11-20T02:54:34 -!- talsit [~talsit@KD182251212127.au-net.ne.jp] has joined ##stm32
2014-11-20T02:54:37 < KreAture_> like the call to init array
2014-11-20T02:54:48 < TheSeven> the bl instruction itself failing?
2014-11-20T02:54:56 < KreAture_> it uses two asm steps and ends up in the hardfault handler instead of the called function
2014-11-20T02:54:59 < KreAture_> yes
2014-11-20T02:55:18 < KreAture_> when it works (other file) I did same steps and it uses 1 step and ends up in the init function it called
2014-11-20T02:55:21 < TheSeven> where the other failing places also some kind of jump instructions?
2014-11-20T02:55:30 < TheSeven> were*
2014-11-20T02:55:31 < KreAture_> no
2014-11-20T02:55:44 < KreAture_> one of em was the activation of the freertos kernel
2014-11-20T02:56:25 < TheSeven> is there by any chance an IRQ hitting at that point?
2014-11-20T02:56:53 < TheSeven> for simple deterministic code, things like systick can actually hit always the same instruction
2014-11-20T02:56:59 < KreAture_> not yet as it's in _start
2014-11-20T02:57:46 < KreAture_> On the other code it may be, but should not be untill you start the scheduler which was what it was doing when the freertos one failed
2014-11-20T02:57:48 < KreAture_> anyway
2014-11-20T02:57:54 < KreAture_> Now there is no such code and it runns fine
2014-11-20T02:58:06 < KreAture_> if I change something now I should get it wonky again
2014-11-20T02:58:08 < qyx_> if you offset it, does it fail?
2014-11-20T02:58:16 < qyx_> ok, dont change "something"
2014-11-20T02:58:17 < KreAture_> lemme stash this and test
2014-11-20T02:58:25 < TheSeven> also, please pastebin your linker script
2014-11-20T02:58:26 < qyx_> try to find some pattern
2014-11-20T02:58:31 < KreAture_> It works now so I need to save it
2014-11-20T02:59:19 < TheSeven> and then pick an arbitrary example (ideally one that fails on a rather trivial instruction), locate the exact failing spot, and check the fault status registers what it complains about
2014-11-20T02:59:34 < KreAture_> I'll add a single command in my hardfault handler as it is early in .text
2014-11-20T02:59:59 < TheSeven> do the fault handlers actually catch the fault, or does the CPU lockup while trying to execute them?
2014-11-20T03:00:38 < KreAture_> it failed!
2014-11-20T03:00:40 < KreAture_> perfect
2014-11-20T03:00:50 < KreAture_> nono
2014-11-20T03:00:59 < KreAture_> they not only catch it, but they fetch all my regs and save the pc etc

2014-11-20T03:02:14 < KreAture_> remove it and it works
2014-11-20T03:02:59 < KreAture_> My app is now stripped down to doing a usb vcp init from st's driver and example, then it runs the loop to see if it is connected, and if so if there is data
2014-11-20T03:03:03 < KreAture_> it then echos data back
2014-11-20T03:03:09 < KreAture_> utterly simple vcp echo
2014-11-20T03:03:23 < KreAture_> no checking of buffers etc so it is horrid, but single char messages echos nicely back
2014-11-20T03:03:26 < brabo> TheSeven: just found in datasheet that before enabling the ethmac clock you need to have selected the rmii iface
2014-11-20T03:03:50 < KreAture_> qyx_ I'll generate map files of the two tests and elfs
2014-11-20T03:04:03 < brabo> i was doing that after, so i put the ethmac clock enables just after selecting the rmii by enabling AFIO_MAPR_MII_RMII_SEL

2014-11-20T03:06:18 < KreAture_> that is the contents
2014-11-20T03:06:26 < qyx_> add another dummy and check again

2014-11-20T03:34:07 < KreAture_> I am manuallt stepping through and seeing it fubar
2014-11-20T03:34:09 < KreAture_> lemme do it again
2014-11-20T03:34:21 < gxti> and yeah, the PC isn't necessarily precise after a fault
2014-11-20T03:34:46 < KreAture_> nop.w uses 2 steps
2014-11-20T03:35:02 < KreAture_> bl too, and then it is in the fault handler

2014-11-20T03:37:06 < KreAture_> a bit higher in the code there is a bl for memset and it is fine jumping to 0x08002900
2014-11-20T03:37:16 < KreAture_> exactly as the address wants
2014-11-20T03:37:37 < KreAture_> the bl is a 4 byte opcode/dataset
2014-11-20T03:38:02 < KreAture_> same as the failing one
2014-11-20T03:38:07 < KreAture_> makes absolutely no sence to me

2014-11-20T13:07:04 < decimad> zyp: I had other stuff to do but was thinking about that gpio stuff (well it can be translated to anything there). I think it's perfectly doable to make a hybrid of static templates vs. dynamic mapping to easily switch between both and use either where it is appropriate. In a library that is used by many it would probably be worthwile to spend the time. However the library community is pretty fragmented it seems. What are your

2014-11-20T17:30:09 < KreAture_> hey dongs
2014-11-20T17:30:19 < dongs> hey dongs
2014-11-20T17:30:23 < KreAture_> :)
2014-11-20T17:30:35 < KreAture_> I got a guy at work to look at the stm32 today
2014-11-20T17:30:47 < KreAture_> he's been working with gcc, iar and keil
2014-11-20T17:30:59 < KreAture_> and been working with the stm32 since it came
2014-11-20T17:31:28 < dongs> was  that the weird chip that was failing or something
2014-11-20T17:31:34 < dongs> i recall some convo from few day ago
2014-11-20T17:31:38 < dongs> barely
2014-11-20T17:31:39 < KreAture_> he could not explain why it does what it does.  we found the commands prior to the fault to NOT affect the r0 register even though it is a load immediate to r0!
2014-11-20T17:31:39 < dongs> cuz im fucking stoned
2014-11-20T17:31:44 < KreAture_> yeah
2014-11-20T17:32:25 < KreAture_> the failing address is in middle of the call to a function too, as in between first and second two bytes of it
2014-11-20T17:32:37 < KreAture_> alignment error on that command
2014-11-20T17:33:14 < KreAture_> The odd thing is the chnage I do that fixes it does not change the first asm lines
2014-11-20T17:33:31 < KreAture_> but when I do the adjustment suddently the mcu does the correct instruction and clears r0
2014-11-20T17:33:44 < KreAture_> you'd really have to see it to believe it
2014-11-20T17:34:11 < KreAture_> mem disassembly looking identical with a different address 8 lines down, and a opcode higher up behaves differently
2014-11-20T17:34:13 < dongs> so what do yu think happened
2014-11-20T17:34:17 < dongs> dust on wafer
2014-11-20T17:34:19 < dongs> ?
2014-11-20T17:34:28 < KreAture_> we are starting to think chip error yes
2014-11-20T17:34:38 < KreAture_> I have ordered a few more boards so we can test
2014-11-20T17:35:14 < KreAture_> a 4 byte opcode/data command can be at a even address right ?
2014-11-20T17:35:21 < KreAture_> doesn't have to be mod4 ?
2014-11-20T17:35:23 < zyp> sure
2014-11-20T17:35:37 < KreAture_> because it really dislikes it
2014-11-20T17:36:20 < KreAture_> It may be combination of the "movs r0, #0" higher up and the 4 byte code further down that triggers the problem
2014-11-20T17:36:42 < KreAture_> whenever I get the fault to move to another function or section it looks similar
2014-11-20T17:37:08 < KreAture_> I did not verify all places that the register it tries to load fails to update, but I found atleast one occurrence where it was same
2014-11-20T17:37:18 < KreAture_> really puzzler
2014-11-20T17:37:38 < KreAture_> Now that I have had some progress though it is "fun" again
2014-11-20T17:37:39 < KreAture_> lol
2014-11-20T17:38:02 < KreAture_> he went over my linker script and the rest of the code including isr's and could not find any reason for the fault
2014-11-20T17:38:14 < KreAture_> we did manage to find the fault code though, which is unknown opcode
2014-11-20T17:38:42 < KreAture_> address matching the middle of the 4-byte code, treated as opcode
2014-11-20T17:39:13 < KreAture_> we will try removing the gcc stuff though, see if that changes anything

2014-11-20T18:07:10 < dongs> Claude: 11.6, 13.3, 1080p yes, shop, likely, i have 1k of the edp transmitter chips on the way, so I hae to get rid of htem at some point :)
2014-11-20T18:07:50 < Claude> nice 11.6 would be a good fit , any rough estimate when you will be ready to ship ?
2014-11-20T18:09:34 < dongs> unsure, im pretty lazy, and its a doublesided assembly, i probably will fab some once the 1k chips arrive end of this month
2014-11-20T18:10:10 < dongs> there's similar chinese trash but their supported panels are usually pretty trash
2014-11-20T18:10:33 < dongs> like boards from njytouch@ebay

2014-11-20T20:50:06 < Tectu_> that letter could have been written by GarageSauce
2014-11-20T20:50:09 < karlp> KreAture_: how did you have 4 byte opcodes? you're not trying to run arm code are  you?
2014-11-20T20:50:11 < Tectu_> that level of engish...
2014-11-20T20:50:47 < karlp> what engish are you talking about? ar eyou guys reading a different apology letter from holiday inn?
2014-11-20T20:51:23 < Tectu_> karlp, well, for me that level of english appears to be quite high
2014-11-20T20:51:28 < Tectu_> but I'm far from being a native english speaker
2014-11-20T20:51:36 < Steffanx> Tectu_: GargantuaSauce's english is better.
2014-11-20T20:52:01 < Tectu_> Steffanx, yes, indeed. and I am sure that nobody on this planet would understand his version of this letter.
2014-11-20T20:52:10 < Tectu_> GargantuaSauce, sorry for wrong nick a few lines above '
2014-11-20T20:52:16 < Steffanx> The letter doesn't meet the unknown word/sentence-ratio
2014-11-20T20:52:46 < Tectu_> Steffanx, GargantuaSauce barely manages to write a single sentence in IRC without me having to opening my dictionary
2014-11-20T20:53:00 < karlp> ok, the use of "engish" made me think you thought it was poorly written.
2014-11-20T20:53:09 < karlp> still no idea what dongs/qyx were surprised about.
2014-11-20T20:53:11 < Steffanx> That's why i said, kind of mr Tectu_ :P
2014-11-20T20:53:37 < Tectu_> klar, nope, the other way around
2014-11-20T20:53:39  * karlp is going to have to watch GargantuaSauce's writings more carefully, hadn't noticed
2014-11-20T20:53:43 < karlp> Tectu_: yeah, I get that now :)
2014-11-20T20:53:44 < Tectu_> karlp, I'd be interested into knowing that as well
2014-11-20T20:54:02 < Tectu_> karlp, just throw yourself into a query with him and start talking about anything. just have your dictonary ready
2014-11-20T20:54:11 < Tectu_> and for clearification, GargantuaSauce, I don't say it's bad :D
2014-11-20T20:54:22 < Steffanx> Tectu_ dont forget karlp is aussie
2014-11-20T20:54:26 < Steffanx> or partially aussie
2014-11-20T20:54:32 < Tectu_> wasn't karlp from zypland?
2014-11-20T20:54:53  * karlp lives sort of near zypland, sortof
2014-11-20T20:55:00 < Tectu_> jpaland?
2014-11-20T20:55:04 < karlp> no, other way
2014-11-20T20:55:06 < Tectu_> sabatonland?
2014-11-20T20:55:12 < karlp> sabaton?
2014-11-20T20:55:13 < englishman> dongs: i dont get it
2014-11-20T20:55:25 < Tectu_> karlp, some swedish power metal band
2014-11-20T20:55:29 < Tectu_> karlp, -> sweden
2014-11-20T20:55:42 < karlp> no, that's the same way as jpaland from zypland
2014-11-20T20:55:47 < karlp> I said the other way :)
2014-11-20T20:55:57 < Steffanx> greenland

2014-11-20T20:57:14 < Tectu_> there is however quite a bid of water between that and zypland

2014-11-20T20:58:58 < Tectu_> is it*
2014-11-20T20:59:00 < englishman> they are only like 1" apart on the map
2014-11-20T20:59:08 < karlp> Steffanx: thanks for correcting him :)
2014-11-20T20:59:24 < Tectu_> yes, I do horribly suck at geography and I hope that nobody is offended

2014-11-20T21:00:10 < karlp> as long as they pay right? ;)
2014-11-20T21:00:10 < englishman> thus their placement is irrelevant

2014-11-21T01:04:31 < Steffanx> did KreAture_ ever dig into the various registers that can tell him something about the reason for the hard fault?
2014-11-21T01:05:11 < Steffanx> manually or using some fancy gdb macros
2014-11-21T01:07:26 < decimad> so hrmmm, I'm a bit puzzled. chibios calls "main" in context of the main-thread. Now I usually don't do any processing in the main function but spawn the worker threads... doesn't that mean memory for the main thread and needless context switches while idling there?
2014-11-21T01:09:02 < karlp> KreAture_: so the "hardfault" elf is wha tsource? is that _meant_ to "work" ?
2014-11-21T01:09:44 < karlp> scrts: does it actually need to be isolated? :) http://www.daycounter.com/Circuits/Transformerless-Power-Supplies/Transformerless-Power-Supplies.phtml
2014-11-21T01:10:35 < karlp> KreAture_: do you have source of this application at all?
2014-11-21T01:12:04 < KreAture_> karlp yes the hardfault and orking elf is almost identical
2014-11-21T01:12:10 < Thorn> fault on svc -> freertos interrupt handlers not installed?
2014-11-21T01:12:40 < KreAture_> I just added a extra access to a memory area to get some extra code in the file, it shifted the rest of the .text section and suddently stuff worked
2014-11-21T01:12:52 < karlp> "almost" is pretty irrelevant if I believe it to be a problem with your environment, not the chip
2014-11-21T01:12:58 < karlp> the "fault" elf does indead "fault" here.
2014-11-21T01:13:03 < karlp> but not sure what that's meant to mean
2014-11-21T01:13:04 < KreAture_> aha!
2014-11-21T01:13:09 < karlp> I suspect it's built badly.
2014-11-21T01:13:12 < KreAture_> atleast that rules out the chip
2014-11-21T01:13:20 < KreAture_> I suspect so too
2014-11-21T01:13:21 < karlp> I never believed it was the chip

2014-11-21T01:15:27 < karlp> yeah, well, maybe those defaults suck
2014-11-21T01:15:34 < KreAture_> that may very well be it
2014-11-21T01:16:01 < karlp> eitehr way, if you can't reduce your code to a freertos blob that can be shared, I'm not going to help any further.
2014-11-21T01:16:29 < KreAture_> I dropped freertos from it and it failed still so that ain't it hehe
2014-11-21T01:16:44 < KreAture_> I can however strip it down to a nice little freertos piece that blinks the led
2014-11-21T01:16:48 < KreAture_> and listens to the button
2014-11-21T01:17:01 < KreAture_> Give me a few secs
2014-11-21T01:17:05 < KreAture_> and see pm
2014-11-21T01:18:03 < karlp> no, I'm goign to bed, and this is good exercise is turning your private project into shareable test cases
2014-11-21T01:18:08 < karlp> this will come in handy fo ryou
2014-11-21T01:19:11 < karlp> I'm seeing the usage ault due to diabled/abset copressor zyp saw too, but I'd say that's just from trying to run data as code
2014-11-21T01:20:26 < KreAture_> karlp I am not new to this
2014-11-21T01:20:31 < KreAture_> I am new to this chip though
2014-11-21T01:20:38 < karlp> well then it shoudl be easy for you ;)
2014-11-21T01:20:58 < KreAture_> I am just used to tools that can actually build a base environment you can use
2014-11-21T01:21:15 < KreAture_> not wasting days trying to get a demo example to work
2014-11-21T01:21:16 < KreAture_> hehe
2014-11-21T01:21:25 < scrts> karlp: basically no.. but I don't trust these :)
2014-11-21T01:21:40 < KreAture_> Since this will be a open project once it works ok, I can't use the tools we use at work
2014-11-21T01:22:06 < KreAture_> also, iar has code limitations on free version and this will definately not be a 32k limit project

2014-11-21T01:36:58 < KreAture_> by shifting the program code a tad creating a extra access to a random memory area

2014-11-21T01:45:47 < KreAture_> anyway, this is most likely a fubared setup/base config but I have no idea what or how, as I normally work with tools that actually do this right...

2014-11-21T02:06:20 < decimad> even though the table definition in the vectors.c contains the correct values, the section seems good to, linker script puts it in the right file...
2014-11-21T02:06:37 < decimad> could this have to do with build order and the weak-attribute?

2014-11-21T02:24:55  * KreAture_ compares the stm32f40x example with his setup to make sure there is no wonky stuff
2014-11-21T02:25:02 < KreAture_> linker script is almost identical
2014-11-21T02:25:09 < KreAture_> whitespaces etc
2014-11-21T02:25:24 < decimad> no it's okay, it works
2014-11-21T02:25:37 < decimad> it's just that the port code doesn't seem to initalize the systick timer
2014-11-21T02:26:11 < decimad> Am I supposed to do it by hand when stuff should start?
2014-11-21T02:26:25 < decimad> since I can't change the port code

2014-11-21T03:24:52 < R0b0t1> yan_: there's the template for inverted F. there are parameters you modify. I mean, technically, everything is variable, but there's most important ones.
2014-11-21T03:25:00 < R0b0t1> yan_: anyway those are a bitch to test so there's papers that tell you good ones
2014-11-21T03:25:28 < R0b0t1> yan_: they may or may not be paired with a device. If the device does not recommend one, you will match the antenna based on the specifications it gives you

2014-11-21T03:49:27 < FransWillem> Hi, I've got a circular buffer being filled by DMA on an STM32F4, and I loop while NTDR doesn't change, and then read a byte from the buffer. I suppose that should work, but sometimes I somehow read the byte before the DMA actually writes it. Is there another way I should be handling this ?
2014-11-21T03:53:01 < zyp> what do you mean by «while NTDR doesn't change»?
2014-11-21T03:53:49 < FransWillem> I wait for NDTR to change, indicating the DMA controller has read a byte from my USART
2014-11-21T03:54:23 < FransWillem> However, it appears NDTR is updated before the actual write to memory, messing up my data :(

2014-11-21T04:01:25 < zyp> that sounds strange, NDTR shouldn't be updated until after the write has successfully completed
2014-11-21T04:03:08 < zyp> is the dma buffer marked volatile so the compiler doesn't take the liberty to move the read to an earlier point or use an already cached value?

2014-11-21T08:49:45 < zyp> one of my friends were going on about that yesterday, how he wanted one
2014-11-21T08:49:55 < zyp> or rather, how he wanted three
2014-11-21T08:50:39 < zyp> so I asked him why the fuck, when a single 4k monitor covers more area than two of those
2014-11-21T08:52:12 < zyp> «yeah, but I want to use it for fullscreen applications, I won't be able to put a fullscreen application on half of a 4k monitor»

2014-11-21T08:54:42 < madist> does it really help you code better if you can see 1000 lines of code at a time ?
2014-11-21T08:55:26 < madist> (i've never had a huge monitor so i have no experience of it)
2014-11-21T08:55:45 < zyp> no, because 1000 lines at 1920 pixels in the height would be unreadable
2014-11-21T08:56:14 < zyp> and personally I don't know
2014-11-21T08:56:46 < zyp> usually my editor window does not fill the whole monitor height, so I've never really wished for more height

2014-11-21T20:31:02 < jadew> but DX is generally more expensive

2014-11-21T20:31:59 < kakeman> stuff took 2-3months to arrive
2014-11-21T20:32:26 < bvernoux> I would avoid buying MCU on ebay or other ...
2014-11-21T20:32:41 < bvernoux> buy it on official distributor
2014-11-21T20:32:46 < bvernoux> else you could have fake stuff ...
2014-11-21T20:33:10 < Steffanx> one can buy fake stuff from official distributor too
2014-11-21T20:33:24 < bvernoux> Steffanx: but they will exchange ;)

2014-11-21T20:33:50 < kakeman> buy it now was 250

2014-11-21T20:34:07 < jadew> I bought CPLDs and FPGAs from aliexpress
2014-11-21T20:34:10 < jadew> they were fine

2014-11-21T20:37:42 < englishman> lol of course dx stuff takes 2-3 months if you get free shipping, it spends 1 month in chinese customs then goes on a boat
2014-11-21T20:37:53 < englishman> dhl or fedex -> 24-72 hours

2014-11-21T21:12:19 < KreAture_> problem is the only demo I can find for stm32f4 and freertos is with coocox
2014-11-21T21:13:01 < KreAture_> anything that sounds like chocolate covered balls is not a ide I can live with saying the name of in public so I don't use it
2014-11-21T21:13:14 < KreAture_> gotta get the options out though
2014-11-21T21:13:47 < jpa-> you can also call it the "lovely dongs ide"
2014-11-21T21:14:01 < KreAture_> he apperas to like it?
2014-11-21T21:14:10 < jpa-> Steffanx: updated (and running out of colors)
2014-11-21T21:14:31 < KreAture_> Then again, not surprised judging by the nick (hihi)
2014-11-21T21:23:36 < decimad2> coocox is eclipse + cdt + arm toolchain - control

2014-11-21T21:24:27 < decimad2> I find the gnu arm embedded plugin sufficient
2014-11-21T21:26:46 < KreAture_> I really really really hate eclipse
2014-11-21T21:27:16 < KreAture_> em::blocks ide editor is much better
2014-11-21T21:27:31 < KreAture_> it's more responsive too and it's lookups are presented in a better manner
2014-11-21T21:28:29 < decimad2> em::blocks is code::blocks forked and half closed source by a single guy
2014-11-21T21:30:29 < decimad2> there's one thing you can fix about eclipse: the looks, the indexer and all and then there's one thing that cannot be fixed: the workspace crap that you cannot move and all.
2014-11-21T21:31:10 < decimad2> But when only coding I don't see any "slowness".
2014-11-21T21:31:10 < KreAture_> hehe
2014-11-21T21:31:12 < KreAture_> well
2014-11-21T21:31:31 < KreAture_> The fact that it integrates templates so nicely and debug etc is enough to sell me
2014-11-21T21:31:50 < decimad2> integrates templates?
2014-11-21T21:31:52 < KreAture_> I am not all that la-di-da on open source
2014-11-21T21:32:05 < KreAture_> well yes you can select your cpu etc and have a blank project set up
2014-11-21T21:32:09 < decimad2> I am against  turning an open source project closed source
2014-11-21T21:32:11 < KreAture_> no copying of files manually
2014-11-21T21:32:22 < decimad2> the arm embedded plugin can do that for you too
2014-11-21T21:32:29 < KreAture_> depends on the licence and how much work he put in
2014-11-21T21:32:33 < KreAture_> now it can
2014-11-21T21:32:41 < KreAture_> when did it start working?
2014-11-21T21:32:48 < KreAture_> couple years?
2014-11-21T21:33:07 < KreAture_> I just hated it when everything was manual
2014-11-21T21:33:07 < decimad2> I don't know since I'm only in the business since 2 weeks ;)
2014-11-21T21:33:20  * KreAture_ 's been at it over 18 years
2014-11-21T21:33:28  * KreAture_ feels old
2014-11-21T21:33:44 < KreAture_> anyway, seems to be some errors in emtools default though
2014-11-21T21:33:48 < KreAture_> emblocks
2014-11-21T21:34:07 < KreAture_> maby just me screwing up but think the -mthumb was missing on the stm32f407
2014-11-21T21:34:15 < KreAture_> may have been the source of all my problems
2014-11-21T21:34:25 < decimad2> though I must admit, the first three days I spent finding a deadlock/path problem with the plugin author
2014-11-21T21:34:26 < KreAture_> I am putting everything back in my test now
2014-11-21T21:34:36 < KreAture_> hehe
2014-11-21T21:34:47 < KreAture_> I get paid to produce, can't sit around fixing bugs
2014-11-21T21:34:55 < KreAture_> yak shaving is for students
2014-11-21T21:36:03 < decimad2> Since then, I have no technical problems... though cdt would deserve a better memory view
2014-11-21T21:38:56 < KreAture_> I just find eclipse not fast enough
2014-11-21T21:39:06 < KreAture_> gui laggs when I type and jump between sources etc
2014-11-21T21:39:22 < KreAture_> also the lookup is not good enough, sometimes it just lacks the data I want
2014-11-21T21:39:28 < KreAture_> never seen that in em::blocks
2014-11-21T21:39:38 < KreAture_> if it's defined, and in scope, it will find it
2014-11-21T21:40:03 < KreAture_> also, the jump to decleration vs implementation is usually more accurate
2014-11-21T21:40:15 < KreAture_> aka it doesn't skip macros etc
2014-11-21T21:40:32 < KreAture_> that might have been fixed on eclipse though as that issue is anchient
2014-11-21T21:40:43 < decimad2> when did you try the cdt indexer last time?
2014-11-21T21:41:06 < KreAture_> hmm, 4 months ?
2014-11-21T21:41:15 < KreAture_> seems about right 4 months yes

2014-11-21T22:10:12 < KreAture_> weird
2014-11-21T22:10:21 < KreAture_> I had this code running right before only crashing all the time
2014-11-21T22:10:35 < KreAture_> hardfaulting every other try on the offsets
2014-11-21T22:10:43 < KreAture_> must have been the thumb instruction as it's fine now
2014-11-21T22:10:45 < KreAture_> :)
2014-11-21T22:10:47 < KreAture_> but slow
2014-11-21T22:10:58 < KreAture_> I tried changing tickcount but it runns the same
2014-11-21T22:11:14 < KreAture_> and my timed delays are 10x  longer than I wanted
2014-11-21T22:11:19 < KreAture_> almost exactly I think
2014-11-21T22:14:01 < karlp> how is KreAture_ still talking about how awesome em:blocks is, when his code randomly crashes
2014-11-21T22:14:20 < KreAture_> karlp my ignorance on a cpu has nothing to do with emblocks
2014-11-21T22:14:21 < KreAture_> hehe
2014-11-21T22:14:31 < KreAture_> karlp and it's not random
2014-11-21T22:14:36 < KreAture_> and it doesn't happen now
2014-11-21T22:14:39 < KreAture_> at all
2014-11-21T22:14:53 < KreAture_> I rebuilt project clean and started afresh adding the options for the cpu
2014-11-21T22:15:10 < KreAture_> I do think there is an error in the template from emblocks though as I managed to get it up manually
2014-11-21T22:15:20 < KreAture_> now pizza time :)
2014-11-21T22:15:29 < Steffanx> bug Tectu_ about that KreAture_ .. he is totally into em::blocks
2014-11-21T22:15:41 < KreAture_> hehe
2014-11-21T22:15:45 < KreAture_> thanks Steffanx I will
2014-11-21T22:15:46 < KreAture_> :)
2014-11-21T22:15:59 < KreAture_> I will do a diff on my project files and setting once I figure out this clock thing
2014-11-21T22:16:09 < KreAture_> then I can see what the change was in the project that magically made it work
2014-11-21T22:16:24 < KreAture_> it MAY have been a bad linker script though as I do see a align by 8 in parts of the code
2014-11-21T22:16:37 < KreAture_> err parts of the script I am using now I mean
2014-11-21T22:16:47 < KreAture_> we'll see

2014-11-22T00:04:44 < TheSeven> it also seems to reset LSION back to zero
2014-11-22T00:05:01 < TheSeven> RCC doesn't have a clock gate, does it?

2014-11-22T00:05:18 < TheSeven> something about backup domain power that needs to be taken care of before enabling LSI?
2014-11-22T00:06:18 < karlp> decimad2: fair enough :)
2014-11-22T00:06:25 < KreAture_> TheSeven should be the same as on most stm's no? with the range possible on the amplifier etc
2014-11-22T00:07:17 < TheSeven> huh?
2014-11-22T00:07:22 < KreAture_> karlp It must be something wrong I do on the settings as the code is just multiple thread examples put into single file to "stress" it a tad
2014-11-22T00:07:55 < KreAture_> It doesn't even start to run buy fails on the first svc 0
2014-11-22T00:08:08 < KreAture_> Maby it's the "svc 0" that is unaligned due to it being asm?

2014-11-22T00:10:42 < KreAture_> since it runs fine and can start the threads when there are fewer of em and less code, the actual supervisor must be ok
2014-11-22T00:10:58 < KreAture_> also it never reaches it as it goes directly from svc 0 to the fault handler

2014-11-22T00:14:21 < decimad2> did you look at the vector table and see if there is a sv call handler?
2014-11-22T00:14:27 < KreAture_> yes
2014-11-22T00:14:39 < KreAture_> and as I said, it worked fine without another bit of code
2014-11-22T00:14:49 < KreAture_> it's like the position of the call matters

2014-11-22T00:25:53 < KreAture_> it's not a new vector list at that address, it's a asm file
2014-11-22T00:25:58 < KreAture_> a function
2014-11-22T00:26:03 < KreAture_> the svc handler
2014-11-22T00:26:10 < KreAture_> and it is where it is supposed to be
2014-11-22T00:26:17 < karlp> you're not putting code in the vector table are you?
2014-11-22T00:26:20 < KreAture_> well, atleast where it has been put
2014-11-22T00:26:24 < KreAture_> lol no

2014-11-22T00:28:07 < KreAture_> seems to be index 11
2014-11-22T00:28:33 < KreAture_> wtf
2014-11-22T00:28:47 < KreAture_> the table contains value 0x800025d

2014-11-22T00:30:10 < decimad2> no
2014-11-22T00:30:28 < decimad2> the 1 off is the thumb bit
2014-11-22T00:30:44 < KreAture_> ahh
2014-11-22T00:30:45 < decimad2> what
2014-11-22T00:30:45 < KreAture_> phew
2014-11-22T00:30:46 < KreAture_> lol
2014-11-22T00:30:50 < KreAture_> I was worried there
2014-11-22T00:30:56 < decimad2> the function must be 2 aligned
2014-11-22T00:31:08 < KreAture_> according to the disassembly it is at 0x0800025c
2014-11-22T00:31:08 < decimad2> what is the "resolving" ?
2014-11-22T00:31:15 < karlp> "magic"
2014-11-22T00:31:27 < decimad2> well, then it's incorrectly placed
2014-11-22T00:31:33 < KreAture_> decimad2 when I asked where the function was located I got one number
2014-11-22T00:31:38 < KreAture_> looking in vector table I got the other
2014-11-22T00:31:46 < decimad2> the pointer in the vector table must be odd
2014-11-22T00:31:51 < KreAture_> so if that is the thumb bit then all is well with the world
2014-11-22T00:31:57 < KreAture_> :)
2014-11-22T00:31:57 < decimad2> telling the processor it points to thumb code
2014-11-22T00:32:01 < KreAture_> cool
2014-11-22T00:32:05 < KreAture_> too bad it doesn't work
2014-11-22T00:32:16 < KreAture_> also, are you sure it is thumb code ?
2014-11-22T00:32:18 < KreAture_> hehe
2014-11-22T00:32:28 < KreAture_> well, it does work just not when I fill the cpu this full
2014-11-22T00:32:32 < decimad2> well, which processor are you working on?
2014-11-22T00:32:38 < KreAture_> stm32f407
2014-11-22T00:32:43 < decimad2> then it's thumb
2014-11-22T00:32:48 < KreAture_> I am currently using 33k flash
2014-11-22T00:32:54 < KreAture_> way below max
2014-11-22T00:32:56 < KreAture_> hehe
2014-11-22T00:33:50 < KreAture_> hmm, so that's not it
2014-11-22T00:33:57 < decimad2> 3 things for svc to work: the vector table has a correct thumb function pointer, you're not in an interrupt that goes before system call priority, there's enough place on the stack for a stack frame
2014-11-22T00:33:58 < KreAture_> dang I thought I was getting close
2014-11-22T00:34:29 < KreAture_> decimad2 the fault description would tell me what triggered it no?
2014-11-22T00:34:42 < decimad2> well what is the fault description?
2014-11-22T00:35:17 < decimad2> and which exception was thrown? usually the fault_handler is used for all sorts of stuff
2014-11-22T00:35:46 < KreAture_> CFSR is 0

2014-11-22T00:39:35 < KreAture_> The faulthandler pics em out for me
2014-11-22T00:40:20 < decimad2> well, if it reaches the fault handler, the vector table placement is good. what's the stack pointer right before the call?

2014-11-22T00:40:26 < KreAture_> I do have the ip
2014-11-22T00:40:28 < KreAture_> lemme connect
2014-11-22T00:40:36 < decimad2> what is the initial stack pointer (stored in the first index of the vector table)
2014-11-22T00:41:09 < KreAture_> 0x200052bc
2014-11-22T00:41:43 < decimad2> is that a thread stack?
2014-11-22T00:41:52 < KreAture_> yes most likely

2014-11-22T00:57:19 < zyp> why are you trying to decode a fault if you're not in a fault condition?

2014-11-22T00:58:57 < KreAture_> agreed

2014-11-22T00:59:25 < decimad2> emblocks broke the cortex?
2014-11-22T00:59:26 < zyp> check that you're actually reading the right addr for CFSR
2014-11-22T00:59:45 < KreAture_> yeh I am going straight to the mem address now
2014-11-22T00:59:55 < zyp> which is?
2014-11-22T01:00:08 < decimad2> remember, the even addresses are on the left side, the odd on the right side!

2014-11-22T01:01:46 < KreAture_> how annoying is that!
2014-11-22T01:01:47 < KreAture_> lol
2014-11-22T01:02:10 < zyp> ok, then I maintain my position that your debugger setup is broken and need to be replaced
2014-11-22T01:02:13 < decimad2> when does this happen btw, right after startup when starting the scheduler?
2014-11-22T01:02:35 < zyp> might be the chip itself, the debugger hardware or whatever software you run for it
2014-11-22T01:03:19 < KreAture_> yes
2014-11-22T01:03:36 < KreAture_> it happens right when it tries to start first task
2014-11-22T01:03:46 < KreAture_> the odd thing is, with less code in the chip it worked
2014-11-22T01:04:18 < decimad2> And when you remove some code now? :)
2014-11-22T01:04:19 < KreAture_> it has to be a assy/build error as it happens on other users chip too
2014-11-22T01:04:27 < KreAture_> I can stash this and rollback
2014-11-22T01:04:28 < KreAture_> 2 secs
2014-11-22T01:05:00 < decimad2> maybe there are relevant changes you're reverting...
2014-11-22T01:05:38 < zyp> are you sure you've not accidentially overclocked the chip or something that makes it wildly unpredictable?
2014-11-22T01:06:15 < decimad2> also there's a meg of flash in that damn cortext, isn't there? 33kb don't sound like pressure
2014-11-22T01:06:55 < zyp> pressure?
2014-11-22T01:07:23 < decimad2> well, that the linker somehow overlaps stuff or something... i mean it should error out anyways...
2014-11-22T01:08:22 < decimad2> that being said, I had faults on svc 0 too... don't remember their cause though
2014-11-22T01:08:42 < KreAture_> hehe
2014-11-22T01:08:44 < KreAture_> nope
2014-11-22T01:08:50 < KreAture_> usb works so it has to be correct
2014-11-22T01:09:03 < KreAture_> it derives the clock from 8 mhz external, divided by 8
2014-11-22T01:09:16 < KreAture_> then multiplied by 336
2014-11-22T01:09:22 < KreAture_> then system clock is that / 2
2014-11-22T01:09:30 < KreAture_> usb clock is that / 7
2014-11-22T01:09:32 < KreAture_> standard stuff
2014-11-22T01:09:41 < decimad2> usually happened when I was trying to debug in ram, had valid code in flash and the bootmode pin was setup for flash i believe
2014-11-22T01:09:50 < decimad2> or maybe also something with the fpu
2014-11-22T01:09:59  * KreAture_ watches his threads dance with the reverted code
2014-11-22T01:11:07 < KreAture_> decimad2 I really really wish you knew why hehe
2014-11-22T01:11:20 < KreAture_> you having em and I having em and I finding ppl on web having em
2014-11-22T01:11:21 < decimad2> oh and then there was this thing that I needed reset & halt before execution of the debug session
2014-11-22T01:11:25 < KreAture_> it seems like a common mistake
2014-11-22T01:11:29 < zyp> KreAture_, do you set the appropriate flash wait state settings first too?
2014-11-22T01:11:46 < KreAture_> zyp the systemInit does that yes
2014-11-22T01:11:59 < zyp> it does, or you just believe it does?
2014-11-22T01:13:26 < KreAture_> ok, let's run slow then...

2014-11-22T01:18:21 < zyp> okay, maybe it's the service call that's promoted to a hardfault instead, and that's why CFSR is 0

2014-11-22T01:18:53 < KreAture_> but, we checked the table
2014-11-22T01:19:02 < KreAture_> it was there
2014-11-22T01:19:03 < KreAture_> hmm
2014-11-22T01:19:16  * KreAture_ removes the handler
2014-11-22T01:19:22 < KreAture_> let's see what it does then
2014-11-22T01:19:31 < zyp> what context are you executing svc from?
2014-11-22T01:20:21 < KreAture_> still cfsr 0
2014-11-22T01:20:33 < KreAture_> I am not, freertos is
2014-11-22T01:20:40 < KreAture_> it is trying to start first task
2014-11-22T01:20:51  * KreAture_ can see how it looks right before
2014-11-22T01:20:52 < KreAture_> 2 secs
2014-11-22T01:20:56 < zyp> set a breakpoint at the faulting svc, check IPSR at that point
2014-11-22T01:21:38 < zyp> you can't execute svc from a handler when the svc handler can't preempt the current handler
2014-11-22T01:22:54 < KreAture_> ok, I am there now

2014-11-22T01:22:59 < KreAture_> lemme see
2014-11-22T01:23:41 < KreAture_> ISR register in xpsr is 0 (user)
2014-11-22T01:24:00 < zyp> ok, so it's not that
2014-11-22T01:24:29 < zyp> IIRC svc handler doesn't need to be enabled, so it shouldn't be that either
2014-11-22T01:25:26 < KreAture_> well, with my change index 11 and index 12 have same handler now
2014-11-22T01:25:58 < zyp> sure, if you don't define a handler, it's usually filled with a default handler
2014-11-22T01:26:37 < KreAture_> They match address to defaultHandler
2014-11-22T01:26:42 < KreAture_> yup
2014-11-22T01:26:48 < KreAture_> just checking that stuff works hehe
2014-11-22T01:33:33 < KreAture_> atleast I got emblocks to save my debug perspective :)
2014-11-22T01:33:45 < KreAture_> I like my windoes where I put em
2014-11-22T01:33:48 < KreAture_> not reset every time
2014-11-22T01:33:49 < KreAture_> hehe
2014-11-22T01:34:10  * KreAture_ adds even more code to the projects
2014-11-22T01:34:20 < KreAture_> never know, may start working again

2014-11-22T01:37:05 < KreAture_> Having tasks in own files and just linking em in is so nice
2014-11-22T01:37:11 < KreAture_> so easy to add stuff
2014-11-22T01:37:13 < KreAture_> :)
2014-11-22T01:40:01 < decimad2> but it'S also a hidden coupling much like the weak-stuff... easy to overlook
2014-11-22T01:40:25 < KreAture_> nah
2014-11-22T01:40:38 < KreAture_> I mean I like to have them in seperate files so they can be reused
2014-11-22T01:40:49 < KreAture_> but I want to "make tasks" in the main for em
2014-11-22T01:40:52 < decimad2> oh, modular design... yeah, thumbs up
2014-11-22T01:40:54 < KreAture_> so I am sure I use em
2014-11-22T01:40:56 < KreAture_> yes
2014-11-22T01:41:00 < KreAture_> love it
2014-11-22T01:41:09 < KreAture_> I do that on lower end micros with protothreads
2014-11-22T01:41:23 < KreAture_> I just want more power for this new project as it will push it
2014-11-22T01:41:29 < decimad2> fix your damn bug already will you!

2014-11-22T01:42:43 < KreAture_> it's silly, I can make a 8 bit 4 MHz micro do multichannel adc sampling, optical io via bit banging, 3G comms to server and external flash storage with wear levelling, all at the same time and not missing a beat
2014-11-22T01:42:56 < KreAture_> and I can't get the stupid stm32 to run without hardfaulting!
2014-11-22T01:42:57 < KreAture_> lol
2014-11-22T01:43:22 < KreAture_> oh and I have it lasting 168-172 hours on a single 600 mAh LiIon cell
2014-11-22T01:43:54 < zyp> «3G comms to server»
2014-11-22T01:43:56 < zyp> yeah right
2014-11-22T01:44:20 < KreAture_> I use Telit mostly
2014-11-22T01:44:24 < KreAture_> modems
2014-11-22T01:44:25 < zyp> exactly
2014-11-22T01:44:43 < KreAture_> they have a stm32 built in to handle the ip stack
2014-11-22T01:44:44 < KreAture_> lol
2014-11-22T01:44:48 < KreAture_> cheating I know
2014-11-22T01:45:04 < KreAture_> uses 64 Mbit flash chip for storage as it can't do µsd cards at those low powerlevels
2014-11-22T01:45:58 < decimad2> Well with 8 bit you have 2^24 less reasons for a bug
2014-11-22T01:46:02 < KreAture_> the 8 bit mcu does handle entire at command protocol though, while doing the other stuff, and it does so in a very orderly, easily expandable early-out command parser
2014-11-22T01:46:07 < KreAture_> LOL
2014-11-22T01:46:09 < KreAture_> true
2014-11-22T01:46:29 < zyp> based on that logic you could build a game controller based on an AVR, plug it into a computer, and then claim that you're playing crysis on it
2014-11-22T01:46:48 < KreAture_> decimad2 my parser uses binary search tree for identifying incoming unsolicited messages fast
2014-11-22T01:47:12 < KreAture_> zyp It does also handle the tcp stream realtime
2014-11-22T01:47:14 < decimad2> you're talking to a noob dude, I don't even know what you mean ;)
2014-11-22T01:47:26 < KreAture_> zyp firmware upgrade of the system takes 6 seconds
2014-11-22T01:47:27 < KreAture_> hehe
2014-11-22T01:47:57 < KreAture_> on the demo with the customer, the cust asked, when does it reboot then?  I mean after the update?
2014-11-22T01:48:14 < KreAture_> I answered: It has rebooted, that flicker you saw on the led was the reboot
2014-11-22T01:48:30 < KreAture_> reboot is 10ms including init and hw checks LOL
2014-11-22T01:48:36 < zyp> big deal
2014-11-22T01:48:43 < KreAture_> he was used to embedded linux
2014-11-22T01:49:02 < decimad2> didn't run systemd, what?
2014-11-22T01:49:06 < KreAture_> lol
2014-11-22T01:49:26 < KreAture_> In some situations you need to start fast, then maby a full os is not needed.  Especially if the task at hand is simple.
2014-11-22T01:50:11 < KreAture_> mcu's are great at that, but when you go from a small rtos to a full linux it usually spells timeconsuming development and/or overkill for the task.
2014-11-22T01:50:30 < KreAture_> Unless you should have gone for a proper computer, in which case it was underkill
2014-11-22T01:50:37 < KreAture_> (is there even such a word?)
2014-11-22T01:51:22 < KreAture_> zyp worst project I did was a log-system with mesh network.  Not sure what I hated the most, the mcu or the radio network
2014-11-22T01:51:38 < KreAture_> mcu was msp430 and the network was Dust networks "smart-dust"
2014-11-22T01:51:48 < KreAture_> The fun part is "dust" in norwegian means "moron"
2014-11-22T01:51:56 < KreAture_> smart-moron
2014-11-22T01:52:00 < KreAture_> hehe
2014-11-22T01:52:10 < decimad2> is your bug fixed yet?
2014-11-22T01:52:23 < KreAture_> anyway, system runs for 5 years on a single Lithium primary cell
2014-11-22T01:52:42 < KreAture_> (unless they use it, haha)

2014-11-22T04:34:51 < emeb_mac> so porting their Matlab stuff to Cuda / C, etc is not really an option and they'll pay to stay in matlab.

2014-11-22T06:50:42 < emeb_mac> upgrdman: what's up?
2014-11-22T06:52:39 < englishman> i'm not an embedded programmer but i play one on irc
2014-11-22T06:52:58 < upgrdman> emeb_mac: weird bug with my code. short post with my code and a video clip here: http://www.eevblog.com/forum/microcontrollers/learning-verilog-have-weird-bug-don't-know-what-to-try/
2014-11-22T06:55:33 < emeb_mac> weird
2014-11-22T06:56:02 < emeb_mac> don't think it's a specific verilog issue. sounds like a synthesis bug.
2014-11-22T06:57:12 < upgrdman> i guess i could try that latest version of ISE. will download the 8GB pile of ISE and see any anything changes. im currently using a version from ~2 years ago.
2014-11-22T06:57:26 < emeb_mac> upgrdman: have you tried different versions of ISE?
2014-11-22T06:57:34 < upgrdman> no, just one.
2014-11-22T06:57:43 < emeb_mac> probably worth trying
2014-11-22T06:57:44 < upgrdman> ise web pack 14.4
2014-11-22T06:57:47 < upgrdman> ya.
2014-11-22T06:58:01  * upgrdman waits impatiently for 8GB to download.
2014-11-22T07:00:12 < englishman> make sure your chip is supported by that version of ise :)
2014-11-22T07:00:19 < englishman> and your operating system :)
2014-11-22T07:00:52 < emeb_mac> newer versions of ise don't usually drop support except for ancient chips

2014-11-22T07:30:32 < hesperaux> anyone know of a good resource to start programming with USB?
2014-11-22T07:30:47 < hesperaux> interested in HID, raw, or serial classes
2014-11-22T07:31:18 < emeb_mac> use the source luke
2014-11-22T07:31:28 < hesperaux> anything less cryptic?
2014-11-22T07:32:00 < hesperaux> i'm hoping to gain an understanding of the protocol before having to debug source code
2014-11-22T07:32:02 < emeb_mac> pick an MCU with a usable USB phy and vendor support. play with it. see what happens?
2014-11-22T07:32:54 < hesperaux> i have an stm32f303 discovery board with a usb device port on it, and I installed stm32cube and got it to appear as my own custom USB-CDC device, but then I don't know what to do after that
2014-11-22T07:33:17 < emeb_mac> there are a lot of different USB class demos
2014-11-22T07:33:24 < hesperaux> and I didn't care for the feel of fucking around with it until it does stuff =/
2014-11-22T07:33:47 < emeb_mac> I suppose you could buy some books and read
2014-11-22T07:34:00 < emeb_mac> I hear Jan Axelson's books are good. Never used em myself
2014-11-22T07:34:17 < hesperaux> ah, good to know. i'll check those out
2014-11-22T07:36:36 < emeb_mac> I've done usb on stm32 with the older stdperiph libs - that's fairly easy to get going.
2014-11-22T07:36:48 < emeb_mac> don't know about stm32cube tho
2014-11-22T07:36:59 < hesperaux> emeb_mac, is there a list of required files for that concoction around somewhere?

2014-11-22T07:37:19 < hesperaux> I managed to get the stm32cube stuff to generate some code and I was able to use it. I don't know about stm32cube...not sure if I like it
2014-11-22T07:37:33 < hesperaux> It reminds me of the cypress API generator, which makes me feel like I don't know what I'm really doing
2014-11-22T07:37:58 < hesperaux> it throws a big HAL into the mix - great if you want cross compatibility, but it confuses me more
2014-11-22T07:38:04 < emeb_mac> hesperaux: don't know about a file list - I just grabbed the demo code and massaged it to work with gcc.
2014-11-22T07:38:13 < hesperaux> ok
2014-11-22T07:38:32 < hesperaux> btw, those are free license packs right?
2014-11-22T07:38:40 < emeb_mac> afaik
2014-11-22T07:38:43 < hesperaux> k
2014-11-22T07:39:01 < emeb_mac> if you want really stripped-down, try zyp's laks stuff
2014-11-22T07:39:06 < hesperaux> I have USB Complete by Axelson here. If it's good I'll consider buying the other books she has
2014-11-22T07:39:14 < emeb_mac> all c++ with some very clean classes for usb
2014-11-22T07:39:37 < hesperaux> hmm. So far I've only used CoIDE with arm gnu. How could I start using C++?
2014-11-22T07:40:21 < emeb_mac> grab Gnu ARM Embedded, install, go
2014-11-22T07:40:35 < hesperaux> so C++ code will Just Work (TM)?
2014-11-22T07:40:51 < emeb_mac> yep
2014-11-22T07:40:53 < hesperaux> nice
2014-11-22T07:41:09 < hesperaux> what OS do you dev on?
2014-11-22T07:41:19 < hesperaux> It would be nice to use Linux. CoIDE is stuck on Windows..
2014-11-22T07:41:29 < emeb_mac> I've got GAE working in linux, mac & windows
2014-11-22T07:41:40 < emeb_mac> I do most work on linux tho
2014-11-22T07:41:54 < hesperaux> GAE?
2014-11-22T07:42:02 < emeb_mac> https://launchpad.net/gcc-arm-embedded
2014-11-22T07:42:11 < hesperaux> ah
2014-11-22T07:42:33 < emeb_mac> no IDE - just editor / compiler / debugger / stlink
2014-11-22T07:42:46 < hesperaux> ok
2014-11-22T07:42:58 < hesperaux> I'm sure that can be integrated into eclipse or whatever
2014-11-22T07:43:21 < emeb_mac> ya
2014-11-22T07:43:39 < hesperaux> I'm used to using ST's standard libraries - do you use something else?
2014-11-22T07:43:48 < emeb_mac> em:blocks is pretty good
2014-11-22T07:44:27 < emeb_mac> I use stdperiph. works fine. some folks think its bloated
2014-11-22T07:44:40 < hesperaux> i noticed that - I tend to agree with you though
2014-11-22T07:45:21 < emeb_mac> I've tried it both ways - stdperiph and direct register writing. direct write is smaller but a pita to maintain.
2014-11-22T07:46:38 < hesperaux> emblocks looks interesting. i will have to try this out
2014-11-22T07:47:23 < emeb_mac> I think it's windows only, but it's fairly clean
2014-11-22T07:47:47 < hesperaux> looks like it is windows only, but it might run faster not being eclipse
2014-11-22T07:49:36 < emeb_mac> yeah, plus it doesn't have all those confusing "perspectives" swapping around.
2014-11-22T07:49:46 < hesperaux> lol
2014-11-22T07:50:25 < emeb_mac> "whoops - you clicked the wrong icon. now everything looks different and you get to hunt for the right one to get you back where you were"
2014-11-22T07:50:43 < hesperaux> yeah not the best design practice, admittedly
2014-11-22T07:50:58 < hesperaux> on the other hand there is so much shit in eclipse they could never fit it all anywhere
2014-11-22T07:51:42 < emeb_mac> ya

2014-11-22T15:13:15 < dongs> hotel was shaking
2014-11-22T15:13:20 < dongs> i even had to put my pants on temporarily
2014-11-22T15:14:32 < Tectu_> did you dong shake too much without?
2014-11-22T15:14:37 < TheSeven> hm... the STM32's internal temperature sensor... is the output voltage of that only proportional to temperature, or also to VDDA?
2014-11-22T15:15:03 < TheSeven> i.e. should I assume it to scale linearly with VDDA or ignore VDDA? what would give more accurate results?
2014-11-22T15:15:54 < karlp> you should use the ivrefcal bytes written at factory
2014-11-22T15:16:03 < TheSeven> yes, but those are at 3.3V
2014-11-22T15:16:08 < karlp> it's linear, but depends on the vref, which depends on voltage
2014-11-22T15:16:09 < TheSeven> what if I run at 3.0V or something?
2014-11-22T15:16:25 < TheSeven> will the TS_CAL values still apply?
2014-11-22T15:16:28 < karlp> measuring the internal ref and scaling to 3v3 and the temp sensor and it's scaling gets you ðretty good temperature
2014-11-22T15:16:32 < TheSeven> or should I scale them by 3.0V/3.3V?
2014-11-22T15:16:34 < karlp> you use both
2014-11-22T15:16:44 < karlp> let me look up some code I have that does it.
2014-11-22T15:17:54 < TheSeven> I can deduce VDDA from the VREF_measured/VREF_CAL
2014-11-22T15:18:25 < TheSeven> but should I factor that into the temperature reading or not?
2014-11-22T15:18:48 < TheSeven> i.e. my VDDA is 3300*VREF/VREFCAL
2014-11-22T15:20:02 < TheSeven> temperature (at 3.3V) is 30 + (TEMP - TS_CAL1) * 80 / (TS_CAL2 - TS_CAL1)
2014-11-22T15:20:21 < TheSeven> but should TEMP there be the raw ADC measurement or ADC_measurement * VDDA / 3300?

2014-11-22T15:55:03 < TheSeven> karlp: IIUC that code assumes that the temperature sensor voltage doesn't depend on VDDA
2014-11-22T15:55:21 < TheSeven> i.e. doesn't scale linearly with VDDA, but does scale linearly with VREFINT
2014-11-22T15:55:32 < TheSeven> (which should be constant)
2014-11-22T15:59:14 < jpa-> what kind of a sensor?
2014-11-22T16:00:11 < TheSeven> stm32's internal temp sensor (adc channel)
2014-11-22T16:00:28 < TheSeven> f030 chip if that matters
2014-11-22T16:06:17 < PaulFertser> TheSeven: afaict, the temperature sensor voltage doesn't depend on VDDA, but to estimate it you need to know current vdda to scale the adc value. I think karlp implies just that.

2014-11-22T16:07:10 < TheSeven> ok
2014-11-22T16:07:45 < karlp> TheSeven: wat? you measure the vrefint, and calibrate _it_ to work out your vdda, then read the temp sensors, and use the calibration values to make up for the difference between your vdda and the calibration values
2014-11-22T16:07:57 < karlp> sorta like what paul said.
2014-11-22T16:08:56 < TheSeven> I know how to get an accurate ADC voltage reading. I just want to know whether the temperatur sensor voltage (which is specified and calibrated at 3.3V) varies with VDDA (somewhat proportionally) or not (stays constant)

2014-11-22T16:09:46 < karlp> there's a section in the manual abotu this  you know.
2014-11-22T16:10:10 < TheSeven> I didn't find anything that comments on how this behaves when VDDA != 3.3V
2014-11-22T16:10:17 < PaulFertser> The manual sucks
2014-11-22T16:11:16 < karlp> A.7.16 even has code for it.
2014-11-22T16:11:29 < karlp> the datasheet talks abotu the temp linearity stuff,
2014-11-22T16:11:34 < TheSeven> which document?
2014-11-22T16:11:48 < karlp> rm0091r7 has sample code, and the datasheet has the voltage/temp behaviours
2014-11-22T16:12:13 < TheSeven> ok, I didn't find anything like that in RM0360
2014-11-22T16:14:27 < karlp> the sample code even has an example of beng at 3v instead of 3.3v....
2014-11-22T16:14:40 < TheSeven> yes, I'm just wondering how to find that whole document ;)

2014-11-22T18:08:08 < Kliment> Anyone know how to get the stlink from the f0 or f4 discovery to talk to a target board running a voltage other than 3.0?
2014-11-22T18:08:52 < Tectu_> is 23$ for a dedicated STLink-v2 really too much?
2014-11-22T18:09:11 < Kliment> Tectu_: No, and I'll have on next week, but I don't have it now
2014-11-22T18:09:18 < Kliment> one*
2014-11-22T18:09:20 < Tectu_> Kliment, sorry for the stupid comment then.
2014-11-22T18:09:55 < Kliment> Tectu_: I'm just wondering where it takes the target voltage from
2014-11-22T18:10:15 < KreAture_> decimad not probable
2014-11-22T18:10:26 < KreAture_> the usb code works fine with 1 other thread as then they do not cross 16k either
2014-11-22T18:11:39 < KreAture_> I get the "svc 0" hardfault whenever I extend the code beyond 1 block it seems
2014-11-22T18:11:40 < Tectu_> Kliment, interesting question. I never bothered but it really seems like this won't work out as there is no target voltage bin when I remember correctly
2014-11-22T18:12:07 < KreAture_> decimad the usb code is very simple too, just the standard usb vcp example
2014-11-22T18:13:02 < KreAture_> pin?
2014-11-22T18:13:42 < decimad> what happens if you bloat the code with an array and without usb?
2014-11-22T18:15:24 < KreAture_> well, I will be making some more threads to see
2014-11-22T18:15:38 < KreAture_> I could also turn off optimizing as it works now with 3 threads no usb
2014-11-22T18:16:27 < KreAture_> ok, code uses 2 blocks now
2014-11-22T18:16:37 < KreAture_> hmm, still works
2014-11-22T18:17:16  * KreAture_ adds some more code
2014-11-22T18:21:55 < KreAture_> now I have some extra dummy code, and my usb stuff compiled in
2014-11-22T18:22:02 < Kliment> Tectu_: Apparently it's 3.3V on the nucleo
2014-11-22T18:22:10 < KreAture_> still works
2014-11-22T18:22:11 < KreAture_> hmm
2014-11-22T18:22:16  * KreAture_ initializes the usb
2014-11-22T18:23:00 < KreAture_> lol still works
2014-11-22T18:23:10  * KreAture_ connects usb cable to check usb function
2014-11-22T18:24:58 < Tectu_> Kliment, just curious, why do you have an STM32 target with less than 3.3V?
2014-11-22T18:25:05 < Tectu_> Kliment, is that some low power application?
2014-11-22T18:25:48 < Kliment> Tectu_: I have it running at 3.3, the f0 and f4 discovery boards run at 3.0
2014-11-22T18:26:46 < Tectu_> Kliment, ooh, that is because they have a shottky diode in series
2014-11-22T18:27:03 < Tectu_> Kliment, that really doesn't matter, 3.3V <--> 3.0V is just fine
2014-11-22T18:27:54 < Kliment> Tectu_: Well, I couldn't get it to work
2014-11-22T18:28:05 < Kliment> Tectu_: It works with the nucleo though, which runs at 3.3

2014-11-22T18:28:44 < KreAture_> 3.3 vs 3 is close tnough
2014-11-22T18:28:47 < Tectu_> Kliment, I'm not that much of a discovery nor nucleo user. I just know that I never had any problems while I did observe the 3.0V thing issue
2014-11-22T18:28:54 < KreAture_> it will work
2014-11-22T18:29:08 < Kliment> KreAture_: I don't know what I'm doing wrong, but it doesn't seem to work
2014-11-22T18:29:26 < madist> and its probably very close to 3.2V not 3.0V
2014-11-22T18:29:33 < madist> for typical schottky at low current.
2014-11-22T18:29:40 < KreAture_> 0.6v (maby 0.5 for safety) or more will cause currents to go through the protection diodes in chip but 3.3/3.2 is fine vs 3v
2014-11-22T18:30:10 < KreAture_> a series resistor of 1k on the signals may be a good idea in any case

2014-11-23T04:16:56 < KreAture_> d32 = USB_OTG_READ_REG32(&pdev->regs.PCGCCTL);
2014-11-23T04:17:05 < KreAture_> why would anyone do this
2014-11-23T04:17:14 < KreAture_> #define USB_OTG_READ_REG32(reg)  (*(__IO uint32_t *)reg)
2014-11-23T04:17:27 < KreAture_> PCGCCTL is a pointer to __IO uint32_t
2014-11-23T04:17:50 < KreAture_> By casting like they do and dereferencing they loose the __IO which is a volatile marker
2014-11-23T04:18:08 < KreAture_> and it generates warnings in compiler
2014-11-23T04:18:23 < KreAture_> result, a tonn of warnings that are simply ignored and other warnings drown in the list
2014-11-23T04:18:53 < KreAture_> d32 = *pdev->regs.PCGCCTL;
2014-11-23T04:19:07 < KreAture_> keeps the volatile during access, creates no warning
2014-11-23T04:19:13 < KreAture_> odd
2014-11-23T04:20:14 < gxti> without the *, yes
2014-11-23T04:23:47 -!- perillamint [~perillami@211.168.182.3] has joined ##stm32
2014-11-23T04:25:07 < KreAture_> no
2014-11-23T04:25:26 < KreAture_> The whole point is to access it
2014-11-23T04:25:31 < KreAture_> to get the value at that time
2014-11-23T04:25:36 < KreAture_> not copy the pointer
2014-11-23T04:25:54 < KreAture_> but stripping the volatile off before dereferencing creates warning
2014-11-23T04:26:27 < gxti> after substitution, the macro way ends up as *(&(PCGCCTL)), in other words no net change in pointery-ness
2014-11-23T04:26:41 < KreAture_> the macro has a cast
2014-11-23T04:26:48 < gxti> yes
2014-11-23T04:27:00 < KreAture_> omg you are right it casts to __IO
2014-11-23T04:27:03 < KreAture_> I didn't see that
2014-11-23T04:27:09 < KreAture_> it actually does keep that
2014-11-23T04:27:12 < qyx_> anyone used internal vref and temperature sensor calibration values?
2014-11-23T04:27:15 < gxti> that doesn't have anything to do with whether it is a pointer, but that is also true
2014-11-23T04:27:20 < KreAture_> but it gives warning about strict type phunning
2014-11-23T04:27:34 < gxti> i'm not saying it isn't stupid, but it isn't incorrect either
2014-11-23T04:27:34 -!- emeb_mac [~ericb@ip68-104-219-12.ph.ph.cox.net] has quit [Read error: Connection reset by peer]
2014-11-23T04:27:49 < KreAture_> no I just don't see why they do it when it gives warnings
2014-11-23T04:27:54 < KreAture_> also, why does it give warning
2014-11-23T04:28:00 < KreAture_> because of the cast?
2014-11-23T04:28:03 < gxti> type punning warnings are often very irritating
2014-11-23T04:28:05 -!- emeb_mac [~ericb@ip68-104-219-12.ph.ph.cox.net] has joined ##stm32
2014-11-23T04:28:13 < KreAture_> yes and they drown important warnings
2014-11-23T04:30:36 < KreAture_> gxti in this case the pointers have struct systems to allow access of individual parts without breaking strict aliasing rules
2014-11-23T04:30:48 < KreAture_> so, it is not needed
2014-11-23T04:31:59 < KreAture_> This in turn is fun since we can change the endianness of the cpu
2014-11-23T04:32:12 < KreAture_> which would make the hw layer fail...
2014-11-23T04:32:26 < KreAture_> Oh don't you just love complexity
2014-11-23T04:32:27 < KreAture_> :)
2014-11-23T04:33:01 < gxti> i'm pretty sure cortex-m does not have that capability.
2014-11-23T04:36:11 < qyx_> cool, calibration values are correct
2014-11-23T04:36:30 < qyx_> actually vref is not 1.21V but 1.184V
2014-11-23T04:37:02 < qyx_> lets try if temp sensor is usable with them
2014-11-23T04:38:36 < KreAture_> gxti you can set endianness of data on it atleast
2014-11-23T04:39:50 < KreAture_> some of the other arm cpu's do have a big endian mode where you swithc the entire thing
2014-11-23T04:40:12 < KreAture_> I remember a guy at work used that for something once, it was clever but ended up biting his ass
2014-11-23T04:40:14 < KreAture_> hehe
2014-11-23T04:40:26 < KreAture_> I think the cleverness ran out when he had to switch chip
2014-11-23T04:40:30 < KreAture_> mid-project

2014-11-23T07:21:38 < upgrdman> R2COM: any ideas? >>> https://www.youtube.com/watch?v=iaubUw9oRuY
2014-11-23T07:27:53 < zyp> wtf
2014-11-23T07:28:32 < zyp> all you change is the name of the module?
2014-11-23T07:29:20 < zyp> the name shouldn't affect the synthesis result in any way
2014-11-23T07:30:39 < upgrdman> zyp: ya no kidding. someone said that the PAR stuff use file checksum as seed for random number it uses to PAR
2014-11-23T07:30:43 < upgrdman> R2COM: will try
2014-11-23T07:31:00 < upgrdman> doing
2014-11-23T07:31:07 < zyp> can you pastebin the source of ps2keyboard.v?
2014-11-23T07:31:21 < upgrdman> yes. one min while i try r2com
2014-11-23T07:32:40 < zyp> even if there's something random involved here, there is nothing in top.v that should show inconsistent behavior
2014-11-23T07:32:56 < upgrdman> hence why i have been pissed off for days :)
2014-11-23T07:33:09 < upgrdman> trying to learn verilog and im getting ass fucked by it
2014-11-23T07:33:11 < zyp> well, being pissed of at xilinx tools is nothing new
2014-11-23T07:33:57 < upgrdman> R2COM: problem persists after cleanup and reloading
2014-11-23T07:35:05 < zyp> hmm, I don't get how the output from rs232 can be inconsistent with leds either, since it's running from the same signal
2014-11-23T07:35:48 < zyp> have you tried scoping the led pin? is it always on?
2014-11-23T07:36:14 < upgrdman> zyp: entire code here:  http://pastebin.com/WiV305TS
2014-11-23T07:36:35 < upgrdman> zyp: yes, scope led
2014-11-23T07:36:47 < zyp> upgrdman, and it's always on, not intermittent?

2014-11-23T07:37:27 < upgrdman> and yes, reverting name fixes it
2014-11-23T07:39:14 < zyp> if you do it all the time, maybe you should consider not using shitty tools

2014-11-23T07:45:31 < upgrdman> that's optional

2014-11-23T08:17:27 < PaulFertser> I've tried drawing a simple diagram with TikZ two days ago. Spent fucking 1.5 hours :/
2014-11-23T08:18:44 < PaulFertser> OTOH having graphics as part of the document gives plenty of advantages: scalability, common style, fonts etc for the whole document, version control, algorithmic and calc facilities...
2014-11-23T08:24:55 < hesperaux> easy and convenient IDE/build environment for linux stm32. any suggestions?
2014-11-23T08:25:41 < hesperaux> oh, I love using Dia
2014-11-23T08:25:46 < hesperaux> Dia diagram editor. use it all the time
2014-11-23T08:26:21 < hesperaux> i used to get msdnaa
2014-11-23T08:26:24 < hesperaux> still use the win7 pro i got
2014-11-23T08:26:51 < hesperaux> upgrdman, my g/f might get one of those soon
2014-11-23T08:26:54 < hesperaux> they are very nice
2014-11-23T08:27:09 < upgrdman> ya.
2014-11-23T08:27:21 < upgrdman> need to play with one in a store, but im fairly certain i'll get one
2014-11-23T08:27:29 < upgrdman> big tablet + stylus would be nice.
2014-11-23T08:27:42 < upgrdman> and full os is nice too

2014-11-23T08:29:43 < upgrdman> just wish windows would catch up in the high-dpi area
2014-11-23T08:29:59 < upgrdman> they only a littler better than linux when it comes to high-dpi support
2014-11-23T08:34:04 < hesperaux> upgrdman, beware of the n-trig stylus in the pro 3
2014-11-23T08:34:07 < hesperaux> the pro 2 has a wacom
2014-11-23T08:34:12 < hesperaux> but i've tried the 3 in stores. very tasty
2014-11-23T08:34:19 < hesperaux> i will even admit to liking windows 8.1
2014-11-23T08:34:21 < upgrdman> :( no wacom?
2014-11-23T08:34:41 < upgrdman> i wonder when they're gonna do a pro 4
2014-11-23T08:34:47 < upgrdman> would hate to buy just before
2014-11-23T08:37:15 < upgrdman> dont want keyboard
2014-11-23T08:37:23 < upgrdman> want big ass tablet, and a stylus
2014-11-23T08:37:27 < upgrdman> no
2014-11-23T08:38:15 < upgrdman> no
2014-11-23T08:38:24 < upgrdman> as a tablet for content consumption
2014-11-23T08:38:29 < upgrdman> youtube, pdfs, etc.
2014-11-23T08:38:46 < upgrdman> mostly pdfs
2014-11-23T08:39:06 < upgrdman> my dickPad 3 is getting old and slow
2014-11-23T08:39:53 < upgrdman> room and outside
2014-11-23T08:40:05 < upgrdman> i find a tablet form factor VERY convenient
2014-11-23T08:40:13 < upgrdman> especially when in bed or on couche
2014-11-23T08:40:17 < upgrdman> couch
2014-11-23T08:41:28 < upgrdman> ya. i spend 1+ hr in bed reading datasheets or watching dicktube videos on verilog or whaever
2014-11-23T08:42:51 < upgrdman> i dont want a keyboard for it
2014-11-23T08:43:01 < upgrdman> and yes, i poked one, and their keyboard sucks ass
2014-11-23T08:43:12 < upgrdman> o
2014-11-23T08:45:12 < upgrdman> i dont type up essays on a tablet
2014-11-23T08:45:37 < upgrdman> it's gonna be 75% pdf reading, 20% youtubing, 5% pc-level shit
2014-11-23T08:45:56 < upgrdman> damn. microsoft is still using the gay ass power supply design.
2014-11-23T08:46:06 < upgrdman> wire -> brick -> wire
2014-11-23T08:46:09 < upgrdman> idiots
2014-11-23T08:46:34 < upgrdman> like apple. SMALL brick -> wire -> done.
2014-11-23T08:47:00 < upgrdman> why the fuck is their tablet psu bigger than my 15" MBP psu
2014-11-23T08:47:15 < upgrdman> maybe they still use vacuum tubes
2014-11-23T08:47:34 < upgrdman> don't care. i'd probably buy they i7 version anyway. like 1500$ or whatever
2014-11-23T08:47:41 < upgrdman> not worried about price
2014-11-23T08:48:04 < hesperaux> upgrdman, it looks like 6-8 months between releases of the surface pros
2014-11-23T08:48:11 < upgrdman> good. i'll wait.
2014-11-23T08:48:22 < hesperaux> the keyboard isn't the greatest but it works. can just use bluetooth if you want
2014-11-23T08:48:28 < upgrdman> should spend some money on a modern fpga dev board before i buy a surface pro
2014-11-23T08:48:53 < upgrdman> 9 years on a laptop?
2014-11-23T08:49:03 < hesperaux> btw the MBP psu sucks horrible ass
2014-11-23T08:49:07 < hesperaux> i replaced it 5 times for mine
2014-11-23T08:49:08 < upgrdman> damn. i get pissed and sell my laptops after ~4 years tops
2014-11-23T08:49:15 < hesperaux> also, same thing: wire brick wire
2014-11-23T08:49:29 < upgrdman> hesperaux: wire is optional on mbp psu
2014-11-23T08:49:34 < hesperaux> fair enough
2014-11-23T08:49:44 < hesperaux> but it's quite heavy hanging off my wall socket
2014-11-23T08:49:50 < hesperaux> R2COM, i do that too
2014-11-23T08:49:57 < upgrdman> also, i've had mine for 1.5yrs now, no problems. two psus, both good. (1 for home 1 for backpack)
2014-11-23T08:50:06 < hesperaux> brb again
2014-11-23T08:50:28 < upgrdman> never had a problem with the weight. i even hang them sideways on some outlets (torquing the ac connector) without problems
2014-11-23T08:50:59 < upgrdman> it is expensive, but my happiness isn't cheap :) ;)
2014-11-23T08:51:38 < upgrdman> and i almost almost no money on "services" so i have money for toys.
2014-11-23T08:51:45 < upgrdman> like i have no cable/sat tv
2014-11-23T08:51:51 < upgrdman> don't go out to movies
2014-11-23T08:51:57 < upgrdman> don't tour places
2014-11-23T08:51:59 < upgrdman> etc
2014-11-23T08:52:10 < upgrdman> i don't drink coffee or have a drug addiction
2014-11-23T08:52:25 < emeb_mac> sounds like a real hoot. :)
2014-11-23T08:52:39 < upgrdman> :)
2014-11-23T08:53:09 < upgrdman> ?
2014-11-23T08:53:35 < upgrdman> lol
2014-11-23T08:53:46 < upgrdman> hot milf would be nice
2014-11-23T08:54:30 < upgrdman> "Windows is installing update 32 of 147" FML
2014-11-23T08:54:48 < emeb_mac> haha
2014-11-23T08:54:57 < emeb_mac> just update to emblocks 2.3
2014-11-23T08:55:00 < upgrdman> i wonder how many kWh microsoft pisses off on updates
2014-11-23T08:55:26 < emeb_mac> what's wrong with 8.1?
2014-11-23T08:55:44 < upgrdman> bbl. time for food.
2014-11-23T08:55:48 < emeb_mac> heh
2014-11-23T08:56:12 < emeb_mac> my 8 insisted on updating itself to 8.1
2014-11-23T08:56:41 < emeb_mac> hard to say
2014-11-23T08:56:59 < emeb_mac> I do know that a lot of engr tools won't run on 8+
2014-11-23T08:57:09 < emeb_mac> like Xilinx ISE
2014-11-23T09:03:13 < emeb_mac> oh look - 2014.3 that came out last month now supports Win 8.1 64-bit
2014-11-23T09:03:27 < emeb_mac> so there's one down at least
2014-11-23T09:03:39 < emeb_mac> ya
2014-11-23T09:04:30 < emeb_mac> I guess it's vivado
2014-11-23T09:04:43 < emeb_mac> wonder if the free webpack will work in 8.1...
2014-11-23T09:05:28 < emeb_mac> ise hasn't changed in more than a year
2014-11-23T09:06:10 < emeb_mac> yep
2014-11-23T09:06:12 < emeb_mac> sux
2014-11-23T09:08:21 < emeb_mac> ya - looks like vivado doesn't support any spartan stuff

2014-11-23T09:12:14 < hesperaux> haven't done a thing with it. don't have a clue what i'm doing
2014-11-23T09:12:32 < hesperaux> i decided to put off learning fpga till some other time
2014-11-23T09:12:45 < hesperaux> too complicated, esp when it has a built-in dual core A9
2014-11-23T09:12:59 < hesperaux> it boots linux for now. yay.
2014-11-23T09:13:15 < hesperaux> i never thought about whether vivado would work on win8

2014-11-23T09:14:37 < englishman> wtf, this stdink doesnt work anymore
2014-11-23T09:14:44 < englishman> just crashes st-link utlitity
2014-11-23T09:14:52 < hesperaux> what?
2014-11-23T09:15:44 < englishman> i agree
2014-11-23T09:17:59 < englishman> segger is working fine
2014-11-23T09:18:02 < englishman> fucking st garbage
2014-11-23T09:18:28 < hesperaux> englishman, sometimes i find the STLink dll needs updating
2014-11-23T09:19:00 < englishman> upgraded drivers, stlink utility, and firmware on two stdinks
2014-11-23T09:19:35 < hesperaux> R2COM, by fullscreen, do you mean a direct rendering window? D3D/OpenGL/etc.?
2014-11-23T09:20:05 < hesperaux> it's possible if the app doesn't grab the mouse
2014-11-23T09:20:24 < hesperaux> but if you click outside, it will minimize the fullscreen program
2014-11-23T09:20:37 < hesperaux> (in most cases at least)
2014-11-23T09:20:50 < hesperaux> I don't know if it can - I just know that most games do that
2014-11-23T09:20:55 < hesperaux> they will minimize if you click out
2014-11-23T09:21:06 < hesperaux> not sure if it's a windows WM thing or a game thing
2014-11-23T09:21:18  * hesperaux would assume it is directx related
2014-11-23T09:22:11 < hesperaux> so besides eclipse + stm32 view on linux, any other good IDEs/toolchains?
2014-11-23T09:22:35 < hesperaux> i'd also like to try out using C++ for stm32, and having a base with the ST standard libs
2014-11-23T09:23:06 < hesperaux> everyone says that but I find they are very functional
2014-11-23T09:23:11 < hesperaux> have you ever used microchip libs?
2014-11-23T09:23:15 < hesperaux> THAT is shit
2014-11-23T09:23:42 < hesperaux> ASF?
2014-11-23T09:23:51 < hesperaux> ah
2014-11-23T09:24:00 < hesperaux> i've actually never used atmel for anything
2014-11-23T09:24:10 < hesperaux> i have some atmels that I sampled a while back, never felt like using them
2014-11-23T09:24:18 < hesperaux> huh
2014-11-23T09:24:23 < hesperaux> i like ST though D:
2014-11-23T09:24:37  * hesperaux doesn't wanna try out a new arch again
2014-11-23T09:24:46 < hesperaux> yeah. on the bright side, it's not MC
2014-11-23T09:25:01 < hesperaux> i tried to use microchip for a year or two, and studied their datasheets and shit for years before that
2014-11-23T09:25:21 < hesperaux> I was really into them, and then one day I raged so hard at the libs and gave up on it
2014-11-23T09:25:39 < hesperaux> Rowley? or Keil? I can't afford any of that shit
2014-11-23T09:25:57 < hesperaux> Either way, same story lol
2014-11-23T09:26:15 < hesperaux> I admit that I did give up on Microchip because of their C libraries.
2014-11-23T09:26:27 < hesperaux> It was between that and the way the chips are configured
2014-11-23T09:26:42 < hesperaux> To get basic UART or somethign running, I had a lot of trouble
2014-11-23T09:26:52 < hesperaux> and there are little gotchas - more than on ST
2014-11-23T09:27:10 < hesperaux> hmm
2014-11-23T09:27:20 < hesperaux> SO cheap
2014-11-23T09:28:04 < hesperaux> i've been using CoIDE in doze so far
2014-11-23T09:28:13 < hesperaux> it works, but it feels a little clunky to me
2014-11-23T09:28:22 < hesperaux> lol
2014-11-23T09:28:30  * hesperaux remembers the phrase "freeshit dildo"
2014-11-23T09:28:53 < hesperaux> what do you consider to be nice?
2014-11-23T09:29:19  * hesperaux wonders what that would be like
2014-11-23T09:31:27 < hesperaux> i require code completion, ease of use for installing libraries, debugging capability with breakpoints, and watch
2014-11-23T09:31:43 < hesperaux> I get all of that with CoIDE, although the libraries aspect is fishy. And I don't know how it handles C++
2014-11-23T09:31:59 < hesperaux> Since it's eclipse based, it can be slow sometimes, too
2014-11-23T09:32:09 < hesperaux> yeah
2014-11-23T09:32:14  * hesperaux feels stuck with that
2014-11-23T09:32:37 < hesperaux> i will concede that. I just can't pay :D
2014-11-23T09:32:52 < hesperaux> kinda sucks. I've seen Keil on the list of things they want on job apps
2014-11-23T09:33:13 < hesperaux> xD
2014-11-23T09:37:40 < hesperaux> anyone here done USB development before?
2014-11-23T09:37:59 < hesperaux> Looking for any kind of OS testing softwares that are useful for getting started on the firmware side
2014-11-23T09:40:29 < hesperaux> i'm interested in writing a device driver for an stm32-attached NRF24L01+
2014-11-23T09:41:07 < hesperaux> basically to use an stm32 as a usb nordic RF adapter
2014-11-23T09:45:54 < hesperaux> dammit. why do they insist on making me use a HAL
2014-11-23T09:46:05 < hesperaux> I can't find the libraries for USB-FS on their site anymore, unless it's from stm32cube

2014-11-23T10:04:01 < GargantuaSauce> my nrf24l01+ driver is nrf_sync.c
2014-11-23T10:04:05 < hesperaux> he uses the VirtualComPort thing
2014-11-23T10:04:16 < hesperaux> GargantuaSauce, is this yours then?
2014-11-23T10:04:26 < GargantuaSauce> rest is copypasta from some german dudes which is copypasta from an old st example i think
2014-11-23T10:05:51 < hesperaux> nrf_sync_TX("Hi, I am a radio bridge lololol."); <---lol
2014-11-23T10:06:43 < hesperaux> i need to send raw packet data from the NRF through to the OS
2014-11-23T10:06:51 < GargantuaSauce> how raw?
2014-11-23T10:07:04 < hesperaux> 32 byte payload from NRF ---> appliction software
2014-11-23T10:07:11 < hesperaux> and vice versa
2014-11-23T10:07:12 < GargantuaSauce> that's precisely what this does
2014-11-23T10:07:54 < hesperaux> does it work both ways?
2014-11-23T10:08:03 < hesperaux> i.e. application software ---> 32 byte payload for NRF
2014-11-23T10:08:32 < GargantuaSauce> yes, keeps the radio in rx mode as long as there's nothing in the tx buffer
2014-11-23T10:10:37 < hesperaux> do you know what causes the usb host to receive the data you TX through VCP?
2014-11-23T10:11:47 < GargantuaSauce> no i still havent bothered to understand usb properly, hence the copypasta
2014-11-23T10:12:04 < hesperaux> ok
2014-11-23T10:12:11 < hesperaux> i'm reading a book right now on USB to hopefully figure that out better
2014-11-23T10:12:29 < hesperaux> apparently the usb host has to request data from the device - if it never requests it, the device just cries to itself
2014-11-23T10:12:35 < GargantuaSauce> yeah
2014-11-23T10:13:05 < GargantuaSauce> i think the acm host driver automagically does it even if you haven't opened the com/tty port though
2014-11-23T10:16:18 < hesperaux> this crap is complicated man
2014-11-23T10:16:23 < GargantuaSauce> yeah
2014-11-23T10:16:59 < hesperaux> thanks for the code to look at though. I'm using F0 for this, so I'll probably rewrite it. Plus, I want to avoid using the discovery board functions
2014-11-23T10:17:31 < GargantuaSauce> i think i've tested the nrf driver on f0 also
2014-11-23T10:17:42 < hesperaux> I have some working nRF code for the F3 and the F4
2014-11-23T10:17:51 < hesperaux> but it's sloppy. need to really neaten it up
2014-11-23T10:18:48 < hesperaux> mostly what I need to get is a working data link between an F0's usb periph and an OS. Probably linux cuz windows makes me sad
2014-11-23T10:19:14 < hesperaux> any tips for software I can use to test usb as I begin writing the firmware?
2014-11-23T10:19:19 < GargantuaSauce> well hopefully a class like acm will work for both
2014-11-23T10:19:35 < GargantuaSauce> i think my future efforts are just going to use libusb
2014-11-23T10:19:52 < hesperaux> I don't really know much about it, but I was going to check into libusb for this
2014-11-23T10:20:30 < GargantuaSauce> in a way it complicates things a lot because you're designing the protocol in addition to the host and device drivers
2014-11-23T10:20:56 < hesperaux> the protocol - the usb protocol?

2014-11-23T10:36:56 < hesperaux> wat
2014-11-23T10:37:33 < hesperaux> so i'm not the only one that does big projects on a breadboard
2014-11-23T10:38:13 < GargantuaSauce> i find breadboards a little too fragile
2014-11-23T10:38:22 < GargantuaSauce> very easy to disrupt one connection while making another
2014-11-23T10:38:26 < hesperaux> fragile? bad connections?
2014-11-23T10:38:34 < hesperaux> ah. yes, that's true in my experience
2014-11-23T10:38:53 < GargantuaSauce> >My 68008 runs at 2 MHz (it was unstable when tested at 4 MHz
2014-11-23T10:38:56 < hesperaux> I won senior design in college with one though :D

2014-11-23T10:40:44 < hesperaux> this website is chock full of stuff
2014-11-23T10:40:55 < hesperaux> ain't nobody got time fo dat
2014-11-23T10:42:18 < hesperaux> oh shit
2014-11-23T10:42:27 < hesperaux> two out of 7 of my raid6 drives are faulted
2014-11-23T10:42:42 < GargantuaSauce> living on the edge eh?
2014-11-23T10:42:47 < hesperaux> as of right now, yes
2014-11-23T10:42:57 < hesperaux> it just started alarming. 15 minutes after the previous one
2014-11-23T10:42:59 < GargantuaSauce> bet they're seagate 3gb ons
2014-11-23T10:42:59 < hesperaux> this is not cool
2014-11-23T10:43:09 < hesperaux> nah, they are WD
2014-11-23T10:43:11 < hesperaux> they were free
2014-11-23T10:43:34 < hesperaux> luckily I have two spares... i was going to grow the array but I guess that's not gonna happen
2014-11-23T10:43:37 < hesperaux> but now I have to rebuild asap
2014-11-23T10:43:48 < hesperaux> it was doing a full backup to the array when this started
2014-11-23T10:44:06 < hesperaux> I thought when the first one failed a while back, after the first full backup, that that was it for a good long while
2014-11-23T10:44:22 < hesperaux> never underestimate drives manufactured for shitty NAS enclosures
2014-11-23T10:46:11 < hesperaux> you've gotta be fuckin kidding me
2014-11-23T10:46:19 < GargantuaSauce> #3?
2014-11-23T10:46:24 < hesperaux> yeah you got it
2014-11-23T10:46:28 < hesperaux> wow

2014-11-23T10:46:35 < hesperaux> when it rains it pours man
2014-11-23T10:46:42 < hesperaux> at least it's a backup array
2014-11-23T10:46:48 < GargantuaSauce> well the stress of rebuilding tips the others over the edge
2014-11-23T10:46:52 < GargantuaSauce> that's generally how it goes i think

2014-11-23T10:47:08 < hesperaux> now my raid5 main disk array has a bad drive
2014-11-23T10:47:12 < hesperaux> the #3 was a 2TB disk
2014-11-23T10:47:14 < hesperaux> fuck my life

2014-11-23T10:47:20 < hesperaux> this is bad man
2014-11-23T10:49:05 < GargantuaSauce> i would shut down the raid and start mirroring the drives individually
2014-11-23T10:49:15 < hesperaux> trying to get control of the box back
2014-11-23T10:49:21 < hesperaux> the backup that i cancelled was still running
2014-11-23T10:49:29 < hesperaux> trying to assassinate that so it stops killing my drives
2014-11-23T10:49:35 < upgrdman> hesperaux: your zybo... is it hard to mess with, or just too much to easily understand?
2014-11-23T10:49:43 < BrainDamage> wasn't there a paper from google how drive fails are extremely correlated and a while array typically starts chain failining with MTBF of 6h?
2014-11-23T10:49:53 < hesperaux> yeah
2014-11-23T10:49:59 < hesperaux> i saw that a while back
2014-11-23T10:50:03 < BrainDamage> so why were you still operating it :|
2014-11-23T10:50:05 < hesperaux> upgrdman, i'll get back to you soon. have to deal with this shit
2014-11-23T10:50:14 < hesperaux> BrainDamage, the first drive failed 15 minutes ago,
2014-11-23T10:50:21 < GargantuaSauce> heat is certainly a big factor also
2014-11-23T10:50:28 < GargantuaSauce> they are probably all at like 65C arent they
2014-11-23T10:50:31 < hesperaux> yeah, they are warm in there >_>
2014-11-23T10:50:41 < hesperaux> i had something sitting in front of the box for the past few days
2014-11-23T10:50:44 < hesperaux> cuz i suck like that

2014-11-23T11:07:01 < PaulFertser> BrainDamage: where's the HA that's RAID supposed to provide then if you have to shut the array down as soon as it degrades? Why run RAID at all then?
2014-11-23T11:07:55 < PaulFertser> Also, have you guys seen data on consumer hard drives which shows their error rate is not really appropriate for the capacity they got nowadays?

2014-11-23T11:13:51 < BrainDamage> PaulFertser: HA? ( sorry i am awful with akronyms ), the main advantage of RAID is redundancy with low spatial overhead ( at least for high raid numbers ), and that when you actually have the fault, you have some tollerance margin on recovering the data vs direct loss, ofc off-site backup is more reliable in that term, but it's not as performant or as cheap
2014-11-23T11:13:54 < BrainDamage> it's just a tradeoff
2014-11-23T11:14:44 < jpa-> often one uses both; backups to keep the data safe, raid to keep the server operating
2014-11-23T11:14:50 < PaulFertser> BrainDamage: I mean RAID is needed only for high availability, backups are still needed.
2014-11-23T11:15:01 < PaulFertser> Yep, exactly my point.
2014-11-23T11:15:25 < jpa-> but for home uses, using RAID for not-so-important-but-nice-to-keep data seems fine
2014-11-23T11:15:45 < jpa-> and in that case, shutting down on first failure is not a big problem
2014-11-23T11:16:20 < jpa-> but i always buy different manufacturers drives for my home raid arrays :)
2014-11-23T11:16:58 < BrainDamage> also if you're doing high availability systems, you can also afford gathering some fault analysis on drives
2014-11-23T11:17:25 < PaulFertser> If you have two drives anyway, why not do automatic backups to one of them? That would be tad more reliable imho.
2014-11-23T11:18:06 < BrainDamage> i'd actually be curious on the fault analysis of spatial, wiring, temp correlation etc
2014-11-23T11:18:40 < BrainDamage> to see how much spatial proximity, wiring proximity etc affect the chain failures

2014-11-23T12:04:41 < GargantuaSauce> are you interpreting the start bit as msb or something
2014-11-23T12:05:06 < GargantuaSauce> triggering on the wrong clock edge perhaps?
2014-11-23T12:12:19 < upgrdman> no
2014-11-23T12:12:39 < upgrdman> output seems fine... i feed that out the serial port and it's always correct

2014-11-23T12:23:25 < GargantuaSauce> it seems likely to me based on that information that you're just interpreting the data incorrectly and the serial port on the other end is doing it correctly

2014-11-23T13:01:57 < hesperaux> two disks died on my raid5 storage
2014-11-23T13:02:02 < hesperaux> 3 disks died on my raid 6 backup array
2014-11-23T13:02:14 < hesperaux> within 15 minutes. they are totally different drives, bought at different times, different capacities
2014-11-23T13:02:22 < hesperaux> i just lost terabytes of data
2014-11-23T13:02:50 < hesperaux> luckily i have an old software raid from a year ago with my old data on it - stuff i can't ever get again if i lost it
2014-11-23T13:03:08 < hesperaux> i was an idiot to keep the backup array in the same storage enclosure
2014-11-23T13:03:28 < GargantuaSauce> MBTF is irrelevant if your house burns down
2014-11-23T13:03:39 < hesperaux> yeah
2014-11-23T13:03:39 < GargantuaSauce> use ~the cloud~, man
2014-11-23T13:03:47  * hesperaux doesn't like the cloud
2014-11-23T13:04:02 < hesperaux> maybe i could triple encrypt it and put it up there - but i don't even have the money for that much cloud storage
2014-11-23T13:04:25 < hesperaux> we have a fireproof safe. maybe putting something in there every so often
2014-11-23T13:04:31 < GargantuaSauce> what do you have terabytes of that is so important
2014-11-23T13:04:43 < hesperaux> eh? not terabytes of important, but definitely hundreds of gigs
2014-11-23T13:04:50 < GargantuaSauce> porn&warez can be downloaded again, sauce and docs are small
2014-11-23T13:05:03 < hesperaux> lots of code, images i made when i did digital art, text and family photos
2014-11-23T13:06:06 < hesperaux> i have like 50G on my box account forever - got a free giveaway once
2014-11-23T13:06:11 < hesperaux> possibly could use that
2014-11-23T13:06:37 < GargantuaSauce> something i want to try is getting a couple cheap "unlimited" hosting provders and see what unlimited actually means
2014-11-23T13:06:42 < hesperaux> lol
2014-11-23T13:06:49 < hesperaux> it's in the TOS
2014-11-23T13:06:55 < hesperaux> read the asterisks
2014-11-23T13:07:04 < hesperaux> some of them use words like "reasonable amount"
2014-11-23T13:07:11 < hesperaux> which means if you annoy them they will bother you with it
2014-11-23T13:07:18 < hesperaux> which is a totally subjective experience
2014-11-23T13:07:44 < GargantuaSauce> yeah
2014-11-23T13:08:42 < hesperaux> i'm going to try to force the disks back online with the LSI card and make it mount the array
2014-11-23T13:09:00 < hesperaux> probably a good amount of the data could be recovered if the FS is intact, which I think it probably is, assuming the firmware allows this
2014-11-23T13:09:11 < hesperaux> this is work - and i have to do it to two of the drives
2014-11-23T13:09:24 < hesperaux> i don't expect to get everything off - but some of it might come off
2014-11-23T13:09:47 < hesperaux> the LSI card is a little bit pickier about SMART than most things
2014-11-23T13:10:43 < hesperaux> it's funny - i was going to upgrade it to raid6 within this month. Haven't been able to yet - it would have saved me here, assuming the raid level migration didn't kill the array (probably would have)
2014-11-23T13:10:51 < hesperaux> i'm starting to despise raid
2014-11-23T13:11:02 < BrainDamage> but but, where's the scientific spirit
2014-11-23T13:11:02 < BrainDamage> we need to quantify
2014-11-23T13:11:02 < BrainDamage> dd if=/dev/urandom of=/sauce
2014-11-23T13:11:23 < hesperaux> ?
2014-11-23T13:12:49 < GargantuaSauce> destructive testing!
2014-11-23T13:13:38 < hesperaux> i'm going to buy a raid1 of two huge disks to use as a backup array - decent plan? The disks would get turned off after each backup completes
2014-11-23T13:13:53 < GargantuaSauce> yeah and store them offsite
2014-11-23T13:14:12 < hesperaux> could do that, to a point
2014-11-23T13:14:22 < hesperaux> i see they have 6T disks now
2014-11-23T13:14:39 < GargantuaSauce> yeah it's pretty amazing
2014-11-23T13:15:39 < hesperaux> expensive though
2014-11-23T13:16:37 < hesperaux> what's the best way to do this
2014-11-23T13:17:03 < GargantuaSauce> that sounds about right
2014-11-23T13:17:05 < hesperaux> are tapes reliable? I have an LTO4 drive with a few 500G tapes
2014-11-23T13:17:22 < GargantuaSauce> well archiving is sort of their use case
2014-11-23T13:17:55 < hesperaux> right, but do they actually last a long time? I mean, they're tapes...
2014-11-23T13:18:01 < hesperaux> won't the earth's magnetic field eventually get the best of them?
2014-11-23T13:18:16 < GargantuaSauce> no data storage solution is permanent
2014-11-23T13:18:19 < GargantuaSauce> well
2014-11-23T13:18:26 < GargantuaSauce> no high-density data storage solution is permanent
2014-11-23T13:18:33 < hesperaux> heh
2014-11-23T13:18:44 < hesperaux> i was considering doing 4-5 blurays or something for the most important stuff
2014-11-23T13:18:52 < hesperaux> but i'd have to buy a bluray burner, etc.
2014-11-23T13:18:59 < GargantuaSauce> i dont think optical disks are any more reliable in the long term
2014-11-23T13:19:00  * hesperaux assumes you can burn blurays now
2014-11-23T13:19:05 < GargantuaSauce> possibly even less so
2014-11-23T13:19:07 < hesperaux> really?
2014-11-23T13:19:13 < GargantuaSauce> yeah
2014-11-23T13:19:19 < BrainDamage> yes, they develop pitting even sitting on a box
2014-11-23T13:19:24 < hesperaux> fail
2014-11-23T13:19:36 < BrainDamage> s/on/in/
2014-11-23T13:19:47 < hesperaux> what else is there...flash?
2014-11-23T13:19:50 < GargantuaSauce> lol
2014-11-23T13:19:54  * hesperaux has no faith in trapped charges
2014-11-23T13:19:59 < GargantuaSauce> rightly so
2014-11-23T13:20:03 < BrainDamage> i have some psx original cd roms with physical holes on the metallic strate
2014-11-23T13:20:42 < GargantuaSauce> i think your 2x harddrive solution is probably the best bet
2014-11-23T13:21:02 < hesperaux> yeah - i guess every 5-10 years i'll have to replace it. the cost of keeping the data I suppose
2014-11-23T13:21:08 < GargantuaSauce> yes absolutely
2014-11-23T13:21:19 < hesperaux> how well do spinning disk drives keep their data?
2014-11-23T13:21:24 < BrainDamage> better if you actually replace upfront
2014-11-23T13:21:31 < GargantuaSauce> on that timescale, just fine
2014-11-23T13:21:37 < GargantuaSauce> past that, not so much
2014-11-23T13:21:38 < hesperaux> that's quite amazing if you think about it
2014-11-23T13:21:49 < BrainDamage> if you /really/ care about data integrity, ordinary maintenance trumps extraordinary
2014-11-23T13:21:49 < hesperaux> i have an 8GB drive from over9000 ago and it still works lol
2014-11-23T13:22:03 < hesperaux> BrainDamage, what do you mean by that?
2014-11-23T13:22:14 < BrainDamage> replace things before failures
2014-11-23T13:22:19 < hesperaux> ah
2014-11-23T13:22:19 < GargantuaSauce> redundancy and replacement
2014-11-23T13:22:22 < GargantuaSauce> continually
2014-11-23T13:22:26  * hesperaux sighs
2014-11-23T13:22:52 < hesperaux> how do you know when that is? that's the hard part
2014-11-23T13:23:14 < GargantuaSauce> depends entirely on how much the data is worth to you i think
2014-11-23T13:23:23 < BrainDamage> if you have the fault statistics, you can actually get a time for a given probability of failure
2014-11-23T13:23:31 < BrainDamage> it's a weibull distribution
2014-11-23T13:23:37 < hesperaux> hopefully storage density won't stop increasing and replacement will occur at times of need - generally quicker than MTBF
2014-11-23T13:23:55 < hesperaux> you can't get MTBF for cheapass consumer disks
2014-11-23T13:24:07 < hesperaux> you can for the REDs or enterprise class - but that's more $
2014-11-23T13:24:16 < GargantuaSauce> you can, it's just measured in HUNDREDS OF HOURS of flying time
2014-11-23T13:24:19 < hesperaux> i like to use the REDs, but one i think just failed
2014-11-23T13:24:42 < hesperaux> before the warranty i might add - all the disks that failed in the primary raid died early
2014-11-23T13:25:02 < hesperaux> the irony of this is that it happened because i was performing a full backup to unreliable disks (hence the raid6)
2014-11-23T13:25:14 < hesperaux> and +1 disk failed in both arrays so as to murder them
2014-11-23T13:25:17 < GargantuaSauce> you should probably stick a fan in front of em
2014-11-23T13:25:25 < GargantuaSauce> and also make sure your ps isnt killing them
2014-11-23T13:25:43 < hesperaux> i did both of those things heh
2014-11-23T13:25:57 < hesperaux> for the past week though i had some shit sitting in front of the enclosure

2014-11-23T13:54:58 < GargantuaSauce> actually that is a thing i think is kind of lacking
2014-11-23T13:55:07 < GargantuaSauce> there needs to be a punch you in the dick feature
2014-11-23T13:55:17 < BrainDamage> smart daemon in loonix can mail you if tresholds are met
2014-11-23T13:55:20 < GargantuaSauce> dbus messages are too transient, system log is only consulted if you already know something is broken
2014-11-23T13:57:00 < GargantuaSauce> i mean a general punch you in the dick feature
2014-11-23T13:57:16 < upgrdman> agreed

2014-11-23T14:01:33 < GargantuaSauce> uhhhhhhhhh
2014-11-23T14:05:53 < hesperaux> yes they complain - but they never got above the threshold i believe
2014-11-23T14:06:03 < hesperaux> by complain i mean put it in the log

2014-11-23T14:06:43 < hesperaux> they were probably around 60C
2014-11-23T14:06:57 < hesperaux> but i can't read the smart data through the LSI card
2014-11-23T14:07:07 < hesperaux> it tells me some of the smart data but not all of it, and i can't query it directly
2014-11-23T14:07:15 < GargantuaSauce> i didnt realize people still used "hardware" raid
2014-11-23T14:07:36 < hesperaux> question: i had to shut off my box to do anything with it cuz I/O was hanging up everything, but I left the drives running (separate SAS enclosure)
2014-11-23T14:07:44 < hesperaux> should I or should I not let them turn off/spin down?
2014-11-23T14:08:04 < GargantuaSauce> lol
2014-11-23T14:08:06 < hesperaux> I'm hoping I can force one back online and copy the data off from a degraded array
2014-11-23T14:08:31 < GargantuaSauce> well any filesystem-level errors you'd introduce have already occurred then
2014-11-23T14:08:39 < hesperaux> yep =/
2014-11-23T14:08:43 < GargantuaSauce> yeah so kill it
2014-11-23T14:08:56 < hesperaux> already wiped the raid card's cache too
2014-11-23T14:09:03 < hesperaux> figured the cache was filled with bad shit anyway
2014-11-23T14:09:15 < GargantuaSauce> you are really keen on losing your data arentcha
2014-11-23T14:09:25 < hesperaux> i'm going to copy out my mlocate database from the livecd before it gets updated - that way i'll have a list of shit that i lost
2014-11-23T14:10:34 < hesperaux> i had to either hook up the array during boot and let it write out the cache, or wipe it - couldn't boot if i didn't make the decision
2014-11-23T14:10:54 < hesperaux> at the time i was most worried about getting old data off of the older raid that was still good onto an external drive

2014-11-23T16:52:00 < decimad2> so there's input, output (push pull), inout (open drain) and analog ... why was it encoded to input, output (push_pull or open-drain) and analog?
2014-11-23T16:52:24 < decimad2> or asked differently, am I the only one that finds it unintuitive?
2014-11-23T16:52:30 < decimad2> *who
2014-11-23T16:52:58 < decimad2> also, why is the input buffer activated for output push-pull?
2014-11-23T16:58:39 < jpa-> because the input buffer is always activated?
2014-11-23T17:04:52 < decimad2> it's deactivated for analog, isnt it?
2014-11-23T17:06:01 < decimad2> anyways, now I know that output can basically also mean input...

2014-11-23T19:22:46 < Getty> for an eeprom like functionality someone would use a bit of the flash memory, right?

2014-11-23T19:27:08 < Getty> Kreature: hehe yeah ;)
2014-11-23T19:27:58 < Getty> Kreature: so what would someone do, to store some bytes on the MCU for the next reboot/loaded hex to catch up?
2014-11-23T19:28:08 < GargantuaSauce> read that pdf
2014-11-23T19:28:15 < Getty> oh sorry, missed that
2014-11-23T19:29:07 < Getty> i have a F107 do they have similar? let me google that, was seeking EEPROM in the datasheet and didnt saw it that confused me
2014-11-23T19:29:21 < GargantuaSauce> yeah theres a similar AN for that series
2014-11-23T19:29:29 < Getty> ok thanks
2014-11-23T19:29:32 < karlp> Getty: how many bytes?
2014-11-23T19:29:44 < karlp> you can also use the option bytes user storage,
2014-11-23T19:29:47 < Getty> nah not many... 512 bytes will be probably enough, might even be 256 bytes
2014-11-23T19:29:57 < karlp> also, depends whether you want reboot safe or power cycle safe
2014-11-23T19:36:12 < Getty> actually we dont reboot at all, i just wanted to make it drastical, as it is good if it would stand a reboot too
2014-11-23T19:36:46 < Getty> cause that leads to  my next topic, "loading" code from storage in run, so far as i understand, it is doable that i can just replace part of the flash memory for execution at any time, right?
2014-11-23T19:37:10 < Getty> so i could like reserve 64k at the end, have a main code in the first 64k and execute "binaries" from a storage, depending on what i wanna do now
2014-11-23T19:37:37 < Getty> (execute == copy into the last 64k and execute it there)
2014-11-23T19:39:11 < GargantuaSauce> i think you just invented the bootloader
2014-11-23T19:40:44 < Getty> yeah no no, i know that bootloader does that ;) but the bootloader is also a no return thing that doesnt care about the stuff before
2014-11-23T19:41:15 < Getty> i was spreading that so detailed out to hope about hearing some problems i dont see in doing it as part of the main program
2014-11-23T19:41:54 < Getty> literally speaking, i want to have a "base" with only picotcp and fatfs, and if a webserver request comes in, the 64k for the webserver are loaded up and do what is needed, else the other 64k are loaded up for doing the "regular job"
2014-11-23T19:42:10 < Getty> does that smells like any problem?

2014-11-23T20:39:50 < Getty> i am coming from the software area.. i must get used to this.... "oh shit i made the mistake 2 weeks ago, and now i cant get it fixed in less than 2 weeks"
2014-11-23T20:40:29 < KreAture_> Imagine doing that in hardware where a new spin of a board cost $20k and takes 4 weeks
2014-11-23T20:40:47 < Getty> that is actually the case here.........
2014-11-23T20:40:59 < KreAture_> reason why we have reviews upon reviews before running a proto
2014-11-23T20:41:04 < Getty> its a production, and we are testing the prototype board, which should get produced 100 times
2014-11-23T20:41:23 < Getty> yeah we are a bit faster here, which is nice, but this little detail about the flash memory size was slipping through
2014-11-23T20:41:34 < Getty> but its not THAT of a catastrophe, just like... 128k is not 256k ;)
2014-11-23T20:41:42 < Getty> simple math
2014-11-23T20:41:43 < Getty> ;)
2014-11-23T20:41:46 < KreAture_> also, someone has the job of getting hold of devboards, breakout boards etc and wiring up proof-rigs if possible so sw ppl can get on with their buisiness immediately and not have to wait so long to actually test
2014-11-23T20:42:08 < Getty> yeah, we are 3 people here, my dad, brabo and me
2014-11-23T20:42:25 < Getty> my dad is like 50< years electronic developer, but this is his first ARM
2014-11-23T20:42:32 < KreAture_> Getty problem is often moving from 8 bit to 32 bit arch, and not realizing that most of the code is going to bloat up due to the word/opcode size
2014-11-23T20:42:38 < Getty> and he is more... electronican minimal, so he thought the "processor which has enough I/O" is fine ;)
2014-11-23T20:42:41 < decimad2> It would take 30 builds a day for a full year to wear the stm32f4 flash...
2014-11-23T20:43:00 < Getty> kreature_: uh, nice hint, i actually made that mistake on my thoughts today, thanks for reminding me ;)
2014-11-23T20:43:11 < KreAture_> decimad2 imagine loading 30 tasks an hour
2014-11-23T20:43:14 < Getty> kreature_: we worked on atxmega before with the project (that was the first first first prototype, before we switched to arm)
2014-11-23T20:43:33 < KreAture_> Getty know the feeling
2014-11-23T20:43:41 < Getty> uh uh uh.... wait
2014-11-23T20:43:47 < decimad2> writing to code and const flash from the app?
2014-11-23T20:43:56 < KreAture_> atmel wanted more from the xmega than they did get though, their original plan had immense routing capabilitys, no more overlapping functions!
2014-11-23T20:44:04 < KreAture_> too bad it wasn't cost effective in silicon
2014-11-23T20:44:12 < Getty> decimad2: yeah..... so you say that is not good?
2014-11-23T20:44:34 < Getty> i should for sure use RAM for this? (i can still get into "microparts")
2014-11-23T20:45:03 < decimad2> well, maybe it's necessary at time (writing to flash from app)... dunno, had no problem like this yet
2014-11-23T20:45:20 < Getty> decimad2: yeah well if you say 30 times a day for a year kill it
2014-11-23T20:45:23 < KreAture_> decimad2 on msp430 I used flash for recording data
2014-11-23T20:45:29 < Getty> decimad2: then every time a webrequest comes in, would kill it in a month
2014-11-23T20:45:40 < Getty> decimad2: thats why you shocked me ;)
2014-11-23T20:45:41 < KreAture_> decimad2 we ended up adding a microsd as the performance hit on realtime tasks when the mcu locks up is too high
2014-11-23T20:45:57 < KreAture_> decimad2 and loading to mem was not an option as we needed all mem for realtime data buffering
2014-11-23T20:46:05 < decimad2> but for debugging and development it's not necessary, also it might need software changes if you debug in ram
2014-11-23T20:46:33 < KreAture_> yeah, realocatable code is a must
2014-11-23T20:46:39 < KreAture_> or very very usefull
2014-11-23T20:47:18 < decimad2> well, it's usually nothing more than a different linker script and maybe some startup macro stuff?
2014-11-23T20:47:20 < KreAture_> I just wish I could get this damn system not to hardfault
2014-11-23T20:47:26 < KreAture_> there MUST be something I am missing
2014-11-23T20:47:55 < Steffanx> tried a different toolchain/ide yet KreAture_? No ::blocks
2014-11-23T20:48:14 < decimad2> i can help you get eclipse running if you need to
2014-11-23T20:48:24 < KreAture_> Steffanx I tried iar as I have it at work
2014-11-23T20:48:33 < KreAture_> Steffanx but freertos port I used was not compatible
2014-11-23T20:48:39 < KreAture_> Steffanx I'd have to swap it out
2014-11-23T20:48:49 < KreAture_> Steffanx also, the usb lib is not iar compatible
2014-11-23T20:49:02 < decimad2> what does the ide care?
2014-11-23T20:49:14 < KreAture_> the compiler uses different pragmas etc
2014-11-23T20:49:24 < KreAture_> 120 places to fix
2014-11-23T20:49:27 < KreAture_> no way
2014-11-23T20:49:48 < decimad2> eclipse is plain gcc arm toolchain...
2014-11-23T20:49:54 < KreAture_> yes
2014-11-23T20:49:58 < KreAture_> and that is the compiler I use now
2014-11-23T20:50:09 < KreAture_> no point in trying gcc with a different wrapper
2014-11-23T20:50:14 < KreAture_> it doesn't work from commandline either
2014-11-23T20:50:18 < Getty> ok i see i have 64k RAM
2014-11-23T20:50:29 < KreAture_> Getty no bigger chip available ?
2014-11-23T20:50:41 < KreAture_> for same package/footprint ?
2014-11-23T20:50:47 < Getty> kreature: yeah sure, there is always a bigger chip, but telling my dad "hey, throw away your design, start over" is not good ;)
2014-11-23T20:50:51 < KreAture_> sometimes they release a even bigger
2014-11-23T20:50:58 < Getty> yeah he must restart over if so, the board is too tight
2014-11-23T20:51:03 < KreAture_> Getty no you misunderstand
2014-11-23T20:51:08 < Getty> the bigger one is 100pin
2014-11-23T20:51:10 < Getty> we have 64pin
2014-11-23T20:51:13 < KreAture_> Getty a DROP IN replacement with exact same pinout
2014-11-23T20:51:30 < KreAture_> usually after 1 year or so on the market, they release a updated larger mem/flash version
2014-11-23T20:51:31 < Getty> yeah i wish ;) STM32F107RTB6 is what we have
2014-11-23T20:51:33 < KreAture_> in same package
2014-11-23T20:51:40 < Getty> the 64pin is hte problem
2014-11-23T20:51:53 < Getty> most stuff is 100pin, the bigger ones are not 64pin
2014-11-23T20:52:30 < KreAture_> how much flash ?
2014-11-23T20:52:33 < Getty> 128k
2014-11-23T20:53:02 < KreAture_> There is a 256
2014-11-23T20:53:04 < Getty> i think we can make it, its an impossible deal, its just like really a breaking point
2014-11-23T20:53:06 < Getty> 64pin?
2014-11-23T20:53:06 < decimad2> Flash memory up to 256 Kbytes and SRAM 64 Kbytes
2014-11-23T20:53:15 < decimad2> that's what f107xx tells me
2014-11-23T20:53:15 < KreAture_> Getty 2 secs looking
2014-11-23T20:53:30 < Getty> decimad2: yeah ;) the other F107 have 256k ;) we know ;)
2014-11-23T20:53:35 < KreAture_> wow st is slow today
2014-11-23T20:53:42 < Getty> kreature: "today"? you are funny....
2014-11-23T20:53:43 < decimad2> flash or ram? what is the problem here?
2014-11-23T20:53:46 < Getty> flash
2014-11-23T20:54:04 < decimad2> no way to save some flash?
2014-11-23T20:54:21 < KreAture_> lqfp 64 ?
2014-11-23T20:54:56 < Getty> yeah well thats what i asked here, and i think with the answers i can work, i am just now still scared about the "making it brick" of the hex if we really do that "all the time"
2014-11-23T20:55:03 < Getty> kreature: yes
2014-11-23T20:55:25 < Getty> s/hex/flash/
2014-11-23T20:55:32 < KreAture_> f103 has much bigger flash and ram
2014-11-23T20:55:33 < decimad2> STM32F107Rx is listed as either 128kbyte or 256kbyte flash
2014-11-23T20:55:38 < KreAture_> but it is probably not pin compatible
2014-11-23T20:55:45 < decimad2> 64 pin qfp
2014-11-23T20:55:48 < KreAture_> decimad2 the larger one has no 64 pin package
2014-11-23T20:56:01 < Getty> thats the problem ;)
2014-11-23T20:56:06 < KreAture_> sorry it has
2014-11-23T20:56:07 < Getty> its like we picked the wrong mistake on the wrong series ;)
2014-11-23T20:56:10 < Getty> it has?
2014-11-23T20:56:11 < KreAture_> there IS a 256 k flash one
2014-11-23T20:56:16 < KreAture_> but it has still 64k ram
2014-11-23T20:56:21 < Getty> 64k ram is fine
2014-11-23T20:56:24 < Getty> which one?
2014-11-23T20:56:25 < decimad2> but flash is the problem!
2014-11-23T20:56:28 < decimad2> STM32F107Rx
2014-11-23T20:56:36 < decimad2> is what you need, it seems
2014-11-23T20:57:04 < Getty> i am confused
2014-11-23T20:57:22 < KreAture_> javascript:void(0)
2014-11-23T20:57:31 < KreAture_> fuck I hate javascript link protections
2014-11-23T20:57:32 < Getty> Rx is the series.... which one is now the specific one with the 64pin and 256k flash?
2014-11-23T20:57:37 < Getty> hahaha :)
2014-11-23T20:57:40 < KreAture_> http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1031/LN1564/PF221026
2014-11-23T20:57:45 < KreAture_> http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1031/LN1564/PF221027
2014-11-23T20:57:51 < KreAture_> Those are your 64 pin options
2014-11-23T20:58:25 < qyx_> Getty: yes, i used F107 with 128 and 256K flash
2014-11-23T20:58:30 < KreAture_> Problem is the dumb fuks at st generate these pages automatically from a database matrix
2014-11-23T20:58:49 < KreAture_> so they just list generic crap
2014-11-23T20:58:58 < KreAture_> lemme find a proper listing for the right chip
2014-11-23T20:59:03 < qyx_> Getty: http://sk.farnell.com/stmicroelectronics/stm32f107rct6/mcu-32bit-cortex-m3-72mhz-lqfp/dp/1737139?ost=stm32f107rct6
2014-11-23T20:59:21 < KreAture_> haha I was just about to do that
2014-11-23T20:59:24 < Getty> oh dear... the price is not nice
2014-11-23T20:59:29 < KreAture_> farnell/newark has proper data
2014-11-23T20:59:30 < decimad2> it's only the 105's that can have 64kbyte flash btw...
2014-11-23T20:59:32 < Getty> i got the chip in front of me
2014-11-23T20:59:38 < Getty> and thats pin compatible?
2014-11-23T21:00:03 < KreAture_> Getty need to check but it may be
2014-11-23T21:00:17 < Getty> yeah well how can that be done most easy now? 8-)
2014-11-23T21:00:32 < KreAture_> find the pinout tables
2014-11-23T21:00:34 < KreAture_> do a diff
2014-11-23T21:00:35 < KreAture_> :)
2014-11-23T21:00:40 < Getty> the question is, if the 128k is not really enough, if you think about using the ram for dynamic details
2014-11-23T21:00:55 < KreAture_> well, 256 helps
2014-11-23T21:01:01 < decimad2> you have all the power now, go use it ;)
2014-11-23T21:01:05 < Getty> we could still let my dad check that up also with availability and stuff
2014-11-23T21:01:50 < KreAture_> rct7 ?
2014-11-23T21:01:51 < KreAture_> http://no.farnell.com/stmicroelectronics/stm32f107rct7/mcu-32bit-cortex-m3-72mhz-lqfp/dp/2333202
2014-11-23T21:04:14 < Getty> yeah that price is not really the direction we wanna go
2014-11-23T21:04:20 < Getty> the current one we would get for a quarter of that
2014-11-23T21:04:34 < KreAture_> actually Getty most of the stm32's are supposed to be pin compatible when sold in same package
2014-11-23T21:04:48 < Getty> kreature: ah thats good to know
2014-11-23T21:04:55 < KreAture_> Getty you are comparing a very expensive supplier with what you have now, stop it
2014-11-23T21:05:00 < KreAture_> lol
2014-11-23T21:05:07 < Getty> yeah i know thats why i said my dad must check the availability
2014-11-23T21:05:56 < KreAture_> the larger chips are expensive though
2014-11-23T21:06:14 < KreAture_> so, assuming a diff chip is pin compatible if in same package, let's see what farnell spits out
2014-11-23T21:06:17 < decimad2> is the application ready yet btw?
2014-11-23T21:06:27 < KreAture_> or digikey for that matter
2014-11-23T21:06:50 < KreAture_> 64 pin lqfp
2014-11-23T21:07:04 < decimad2> maybe it'll just be 1 256kb for development and then scale it down if possible?
2014-11-23T21:08:06 < Getty> decimad2: no thats why we can still play with other concepts
2014-11-23T21:08:17 < Getty> decimad2: thats why i feel its highly doable with 128k
2014-11-23T21:08:22 < KreAture_> http://www.digikey.com/product-detail/en/STM32F205RET6TR/STM32F205RET6TR-ND/4357571
2014-11-23T21:08:42 < decimad2> i can't follow
2014-11-23T21:08:43 < Getty> itmight be wise to go from start on with inventing a little "executables" concept
2014-11-23T21:08:54 < KreAture_> just don't waste too much dev in working around chipsize as it is sooooo much cheaper to switch
2014-11-23T21:09:09 < KreAture_> You need to sell thousands upon thousands for it to be worth while saving a buck on each board
2014-11-23T21:09:16 < KreAture_> and using 1000 hours of dev time
2014-11-23T21:09:31 < Getty> thats what i told my dad ;) but he insisted on the 64pin, i didnt knew at that point about the 128k flash, that would have been a more valid argument from my side
2014-11-23T21:09:37 < decimad2> scaling it down after the app is down comes for free basically
2014-11-23T21:09:43 < Getty> hahahah 1000 hours of dev time ;)
2014-11-23T21:09:51 < KreAture_> Getty 1000 is not uncommon
2014-11-23T21:10:03 < Getty> yeah not for us ;)
2014-11-23T21:10:07 < decimad2> 1000 hours on a microcontroller project?
2014-11-23T21:10:17 < KreAture_> Projects easily go in the 1000-3000 hours range if the customer is not 100% sure on what he wants
2014-11-23T21:10:22 < Getty> JUST for the C code in this case ;)
2014-11-23T21:10:26 < KreAture_> decimad2 that is with hardware and enclosure too
2014-11-23T21:10:31 < Getty> and even you say it like specific the change from256k to 128k
2014-11-23T21:10:42 < decimad2> okay, well, if you have changing demands then it always sucks
2014-11-23T21:11:00 < KreAture_> decimad2 and you need to make a enclosure that needs to be drop tested, ip 67 etc
2014-11-23T21:11:14 < Getty> i have my customer under control, he goes with us fully, no distraction there luckily
2014-11-23T21:11:15 < KreAture_> not to mention if you need any american certificates or maby use in canada
2014-11-23T21:11:29 < decimad2> well, that's second unit problems ;)
2014-11-23T21:11:47 < KreAture_> decimad2 it pais to think of emi on first unit
2014-11-23T21:12:20 < KreAture_> anyway, it is worth checking of stm32f205 is pin compatible with the one you use
2014-11-23T21:12:28 < KreAture_> 512k flash, 132k ram
2014-11-23T21:12:46 < KreAture_> assuming you have no special requirements like usb or mac/phy
2014-11-23T21:13:29 < qyx_> F2 is not, there are some changes required
2014-11-23T21:13:35 < qyx_> i mean F1 and F2
2014-11-23T21:13:37 < Getty> kreature: thats a sexy change ;)
2014-11-23T21:14:01 < qyx_> there are compatibility notes in the datasheets
2014-11-23T21:14:16 < KreAture_> qyx_ st sais they try and make the same packages pinout compatible if they can
2014-11-23T21:14:22 < KreAture_> yeh
2014-11-23T21:14:39 < KreAture_> I saw some sheet with a compatibility matrix once
2014-11-23T21:14:42 < KreAture_> just can't find it
2014-11-23T21:14:58 < KreAture_> F1 and F3 are compatible
2014-11-23T21:17:56 < decimad2> what's the usual process? I believed that it would be more natural to develop the software on a big dev board with breakouts and then do the specific circuit?
2014-11-23T21:17:58 < KreAture_> https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0CB0QFjAA&url=http%3A%2F%2Fwww.st.com%2Fweb%2Fen%2Fresource%2Ftechnical%2Fdocument%2Fapplication_note%2FDM00073522.pdf&ei=3zJyVPCpOIKWOJvygdAJ&usg=AFQjCNG9cl8E9i0I_ysX7EKj4v31cqVmaw
2014-11-23T21:18:00 < KreAture_> shit!

2014-11-23T21:18:03 < KreAture_> fuuuu
2014-11-23T21:18:32 < Getty> kreature: f3 now? what the hell? 8-)
2014-11-23T21:18:39 < Getty> i am just going through that f205 thing
2014-11-23T21:18:51 < KreAture_> lol
2014-11-23T21:19:01 < KreAture_> I am trying to find what st ment to be compatible
2014-11-23T21:19:17 < KreAture_> did you atleast get the pdf from second link ?
2014-11-23T21:20:07 < Getty> yeah i am seeing it
2014-11-23T21:23:58 < Getty> but i need network, i am now a bit confused but i just check farnell, aehm.... confused... aehm...
2014-11-23T21:24:17 < qyx_> then you have only F207 or F107 options
2014-11-23T21:24:23 < qyx_> err
2014-11-23T21:24:26 < qyx_> F407 also
2014-11-23T21:25:05 < KreAture_> http://www.st.com/web/en/resource/technical/document/application_note/DM00073522.pdf
2014-11-23T21:25:06 < decimad2> just check the datasheet of the device lines, they all come with a chapter "device overview"
2014-11-23T21:25:07 < KreAture_> finally
2014-11-23T21:25:13 < qyx_> if you can do minor changes to your pcb, you can use F407
2014-11-23T21:25:14 < KreAture_> I installed "don't track me google"
2014-11-23T21:26:22 < Getty> http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1577/LN11 here it shows no 64pin of that
2014-11-23T21:26:23 < Steffanx> Google installed: Haha, I still do track your silly arse all over the web
2014-11-23T21:26:28 < Getty> the F407/F417
2014-11-23T21:26:42 < qyx_> oh, i forgot
2014-11-23T21:26:49 < KreAture_> Steffanx it just prevents indirect results in searches
2014-11-23T21:26:50 < qyx_> if you want ethernet in 64pin, F107 is the only option
2014-11-23T21:27:00 < KreAture_> Steffanx which allows you to copy/paste results cleanly
2014-11-23T21:27:29 < Getty> qyx: ok then we already are right with accepting our fade
2014-11-23T21:28:02 < qyx_> just grab bigger F107
2014-11-23T21:28:32 < qyx_> when i ordered from farnell last time, 256K version was even cheaper than 128K
2014-11-23T21:30:42 < decimad2> it takes that extra production step to fuse away the 128k...
2014-11-23T21:31:21 < Getty> but the 256k version is a 100pin
2014-11-23T21:31:31 < Getty> thats the core of the problem ;)
2014-11-23T21:31:33 < decimad2> that's the wring 256k version
2014-11-23T21:31:36 < decimad2> *wrong
2014-11-23T21:31:48 < Getty> so there is a F107, with 64pin, network and 256k?
2014-11-23T21:31:49 < decimad2> there is a 64 qfp 256kb version
2014-11-23T21:31:53 < Getty> with network?
2014-11-23T21:31:57 < decimad2> yes
2014-11-23T21:32:04 < Getty> ok which one then?

2014-11-23T21:33:48 < Getty> i think you did, but then you all confused me with the 207 307 and all
2014-11-23T21:33:56 < decimad2> the C is the important bit that says 256kb please
2014-11-23T21:35:47 < decimad2> the B would say: 128kbyte please

2014-11-23T21:46:59 < rewolff> There is no "A" for 64k. The marking for 64k is "8".
2014-11-23T21:47:04 < rewolff> Right?
2014-11-23T21:47:28 < decimad2> well, I was guessing, might be wrong
2014-11-23T21:47:34 < rewolff> http://sk.farnell.com/stmicroelectronics/stm32f030r8t6/mcu-32bit-cortex-m0-48mhz-lqfp/dp/2393636?ost=stm32f030r8
2014-11-23T21:48:59 < Getty> stupid question, can someone explain to me how its worth for the producers to make such a variation amount of those MCUs? it feels a bit also that the prices are so random through that
2014-11-23T21:49:29 < rewolff> Part of that "randomess" is Farnell.
2014-11-23T21:49:30 < Getty> i bet there is more than one example where an identical pin setup better one is always cheaper
2014-11-23T21:50:47 < rewolff> I would make up "rules" for the pricing department like: "add at least 100% margin on components costing less than $1 and quantity less than 10"
2014-11-23T21:51:14 < rewolff> but apparently the don't do that, so you get wildly varying prices for the small quantities of cheap items.
2014-11-23T21:51:20 < rewolff> *they
2014-11-23T21:51:21 < upgrdman> karlp: yes, i like the analog discovery. awesome little tool.
2014-11-23T21:51:35 < karlp> the software is windows only isn't it?
2014-11-23T21:51:51 < gnomad> Getty: capitalism.
2014-11-23T21:52:24 < gnomad> slash free market economies.
2014-11-23T21:53:15 < rewolff> Anyway, so the A versions of atmel chips are sometimes cheaper, sometimes not, and sometimes there is a crossover depending on how many you want.
2014-11-23T21:53:29 < upgrdman> karlp: ya
2014-11-23T21:54:00 < upgrdman> they released an SDK though. not sure if anyone did something with it.
2014-11-23T21:54:27 < rewolff> karlp: Re: my TIM2 bugreport:  do you want my full source? Do you have an '030 to test?
2014-11-23T21:55:05 < karlp> no, I have the original f051 disco and that's all, I'm just goign on my reding of the ref mans so far
2014-11-23T21:57:04 < karlp> sorry, was just reading your reply,
2014-11-23T21:57:35 < karlp> so, your problem is that you used RCC enable TIM2, nvic setup TIm2, and tim2 actually worked,
2014-11-23T21:57:43 < karlp> but it's not documented to exist on f030..
2014-11-23T21:57:59 < karlp> I'm not sure what you want me to change in libopencm3 from that though
2014-11-23T21:58:31 < rewolff> hmmmmm
2014-11-23T21:58:38 < rewolff> maybe you're right.
2014-11-23T21:59:29 < rewolff> I really THOUGHT that STM had put what they called TIM3 on the spot of TIM2 on other CPUs and that THIS was what made it work.
2014-11-23T22:01:00 < rewolff> (Just like the smaller ones might not have SPIx and USARTx and then "rename" the other ones, so you get "Note1: this pin does USART1_RX on small devices and USART2_RX on bigger devices"
2014-11-23T22:01:01 < karlp> yeah, as far as I can read the two ref manuals, tim3 is always in the same address, tim2 is always at the same address, and the f030 ref man just doesn't mention tim2
2014-11-23T22:01:22 < zyp> Getty, 512k is E in case you actually wanted to know
2014-11-23T22:02:02 < rewolff> So I seem to have an '030 with "officially dead" silicon on it.
2014-11-23T22:02:07 < rewolff> but working in practise.
2014-11-23T22:02:12 < zyp> no big surprise
2014-11-23T22:02:22 < zyp> lots of stm32 chips have that
2014-11-23T22:02:34 < karlp> more flash, more ram, more periphs.
2014-11-23T22:02:36 < rewolff> So previous time I THOUGHT I had a '030... and found a working I2S module....
2014-11-23T22:02:39 < zyp> bunch of chips comes with twice the amount of flash you paid for
2014-11-23T22:02:39 < karlp> "pick your donation level"
2014-11-23T22:03:01 < decimad2> the problem is when they decide to cut them physically one day...
2014-11-23T22:03:06 < rewolff> which was documented to be only available on  '051,
2014-11-23T22:03:15 < rewolff> but it turns out I DID have a '051....
2014-11-23T22:03:54 < zyp> and f405 had a fun case of «does not have OTG_HS», which got updated in some RM revision to «oh, now it does have OTG_HS»
2014-11-23T22:04:35 < rewolff> I have the impression that with the current fab-process they can't make bigger chips (> 16 or is it 32k flash) in a size that fits the SO20 package.
2014-11-23T22:04:55 < rewolff> So it would be unlikely to find a bigger-flash-chip in that package.
2014-11-23T22:05:28 < zyp> oh, there are actually SO20 stm32s now?
2014-11-23T22:05:46 < rewolff> tssop20. Sorry.
2014-11-23T22:05:54 < zyp> either way
2014-11-23T22:06:02 < zyp> haven't noticed those
2014-11-23T22:06:21 < rewolff> http://nl.farnell.com/webapp/wcs/stores/servlet/Search?catalogId=15001&langId=31&storeId=10168&gs=true&st=stm32f030f
2014-11-23T22:06:34 < zyp> but I tend to not care about chips that doesn't support usb :)
2014-11-23T22:06:43 < rewolff> :-)
2014-11-23T22:07:02 < rewolff> 072 has USB, but no F-package.
2014-11-23T22:07:14 < zyp> I know
2014-11-23T22:07:16 < rewolff> (F in package position means tssop20).
2014-11-23T22:07:24 < zyp> l052 also
2014-11-23T22:07:34 < zyp> I just designed a board for the latter
2014-11-23T22:07:37 < rewolff> Hmm. hadn't noticed that one yet.
2014-11-23T22:07:57 < zyp> l0 is M0+ whereas f0 is only M0
2014-11-23T22:08:11 < bvernoux> does anyone here have done a design with ESP8266 ?
2014-11-23T22:08:33 < zyp> and the lack of a bunch of nice stuff in M0 makes it kinda unappealing to me
2014-11-23T22:09:04 < rewolff> Hmm. None of the usual suspects (for me) has the '052...  (except for the discovery board) .
2014-11-23T22:09:19 < zyp> M0 compared to M0+ lacks both SCB_CFSR and SCB_VTOR
2014-11-23T22:10:20 < zyp> the former is nice for debugging faults, and the latter is pretty much a requirement for any project using a custom bootloader
2014-11-23T22:17:33 < KreAture_> zyp I would rather something just not do anything than create a hardfault from a simple port mishap
2014-11-23T22:18:05 < KreAture_> also, sometimes you really want to be able to use a port register even though it is not set for output, hack to store a word
2014-11-23T22:18:46 < qyx_> why would you do that?
2014-11-23T22:23:14 < zyp> KreAture_, huh?
2014-11-23T22:23:34 < karlp> KreAture_: wat drugs are you taking here? < KreAture_> Getty problem is often moving from 8 bit to 32 bit arch, and not realizing that  most of the code is going to bloat up due to the word/opcode size
2014-11-23T22:24:42 < zyp> heh
2014-11-23T22:25:21 < zyp> isn't thumb/thumb2 generally more efficient than common 8-bit procs?
2014-11-23T22:26:35 < zyp> also, isn't AVR also using 16-bit opcodes?

2014-11-23T22:48:11 < KreAture_> zyp call it what you want but I always find equivialent code or same libs grow when moved to 32 bit
2014-11-23T22:48:47 < KreAture_> it's only if you are doing heavy stuff or 16/32 bit math on a 8 bit mcu that you really gain and see it shrink
2014-11-23T22:49:13 < KreAture_> there's a reason you see a general trend for more flash on a 32 bit than a 8 bit
2014-11-23T22:49:16 < KreAture_> you need it
2014-11-23T22:49:26 < KreAture_> it is faster/more effichient yes
2014-11-23T22:49:30 < KreAture_> but not more dense

2014-11-24T00:02:05 < KreAture_> a pc app controlled the steppers and allowed any pitch wind etc
2014-11-24T00:02:22 < KreAture_> By adding glue with a brush you layed up complex winding patterns if need be
2014-11-24T00:02:26 < KreAture_> worked quite well
2014-11-24T00:02:35 < KreAture_> we used it to make prototype coils and antennas etc
2014-11-24T00:02:47 < kakeman> nice
2014-11-24T00:03:01 < KreAture_> It's basically a situation where I didn't have time to wait for someone to decide we could order a coilwinder
2014-11-24T00:03:06 < KreAture_> so I built one in 2 evenings
2014-11-24T00:06:18 < kakeman> just remembered to add some stepper controllers to list
2014-11-24T00:09:22 < kakeman> is there even excuse to design own stepper board for random derp when chinaman sell stuff for two bucks

2014-11-24T00:10:29 < KreAture_> since china does 50x50mm boards for same price as 25x50mm I doubled each board
2014-11-24T00:10:38 < KreAture_> 10 boards for $9.9
2014-11-24T00:10:44 < KreAture_> 20 channels

2014-11-24T00:14:22 < KreAture_> same boards
2014-11-24T00:14:24 < KreAture_> I ordered from both
2014-11-24T00:14:25 < KreAture_> :)
2014-11-24T00:14:42 < KreAture_> http://kreature.org/projects/3d_printer/controller/seedstudio_vs_elecrow/2_seeedstudio.png
2014-11-24T00:14:48 < KreAture_> http://kreature.org/projects/3d_printer/controller/seedstudio_vs_elecrow/2_elecrow.png
2014-11-24T00:14:59 < KreAture_> Notice how elecrow expanded my stop mask
2014-11-24T00:15:34 < KreAture_> some of that is my own fault for selecting a different color
2014-11-24T00:15:39 < KreAture_> green is a dry film
2014-11-24T00:15:44 < qyx_> wut
2014-11-24T00:15:47 < KreAture_> the others are a liquid film
2014-11-24T00:15:59 < qyx_> yep, their mask seems to be a bit crappy
2014-11-24T00:16:17 < KreAture_> seeedstudio alignment and such is spot on
2014-11-24T00:16:23 < KreAture_> very happy with it
2014-11-24T00:16:31 < KreAture_> all my boards have always been that good from them
2014-11-24T00:16:45 < kakeman> what are those potentiometers for?
2014-11-24T00:17:01 < kakeman> on controller board?
2014-11-24T00:17:12 < KreAture_> setting current and the threshold between fast and slow decay
2014-11-24T00:17:22 < kakeman> oh
2014-11-24T00:17:25 < KreAture_> allows you to tune it better for high or low speed
2014-11-24T00:17:33 < KreAture_> depending on where you need the most accuracy
2014-11-24T00:17:34 < KreAture_> etc
2014-11-24T00:17:41 < KreAture_> I will be using digipots on later versions
2014-11-24T00:18:40 < KreAture_> and most likely dropping the one for the fast/slow decay
2014-11-24T00:18:58 < KreAture_> there's a lot of extra electronics on tha boards to detect any thermal trip events
2014-11-24T00:19:01 < kakeman> is there anything underside of board?
2014-11-24T00:19:09 < KreAture_> no
2014-11-24T00:19:14 < KreAture_> backside is all cooling
2014-11-24T00:19:23 < KreAture_> I do not even use protruding pinns
2014-11-24T00:19:29 < KreAture_> all coated with solder stop
2014-11-24T00:19:33 < kakeman> ye
2014-11-24T00:19:40 < KreAture_> thermals under the chip bring heat down to underside
2014-11-24T00:19:50 < KreAture_> it can be slapped onto a cooling fin or even mounted to chassis
2014-11-24T00:20:08 < KreAture_> http://kreature.org/projects/3d_printer/controller/assy/IMG_2568.JPG
2014-11-24T00:20:14 < KreAture_> 3-4 amps test
2014-11-24T00:20:16 < KreAture_> :)
2014-11-24T00:20:51 < KreAture_> what is interesting with the drv8811 is the over-current trip point is thermally dependant
2014-11-24T00:21:05 < KreAture_> keep the chip under 70c or so and you can get away with over 4 amps
2014-11-24T00:21:21 < kakeman> nice
2014-11-24T00:21:41 < kakeman> that is nice looking module
2014-11-24T00:22:21 < kakeman> my board has step-down converter, mcu and 2 drivers
2014-11-24T00:22:32 < kakeman> nasty
2014-11-24T00:22:33 < KreAture_> These are dumb boards
2014-11-24T00:22:44 < KreAture_> the plan is to make a adapter board to connect them to a stm32 board
2014-11-24T00:22:57 < KreAture_> later I will embed the stm32 on a main board and just stack on these controllers
2014-11-24T00:23:03 < kakeman> I think I should design some dumb boards too
2014-11-24T00:23:18 < KreAture_> since the stepper drivers are expensive user only attaches as many as he needs
2014-11-24T00:23:24 < kakeman> I just happen to have specific aplication for some of these
2014-11-24T00:23:53 < KreAture_> http://kreature.org/projects/3d_printer/controller/stm32/stm32_test-bench_5.jpg
2014-11-24T00:23:56 < kakeman> yes
2014-11-24T00:24:03 < KreAture_> I always rig up these rigs
2014-11-24T00:24:06 < KreAture_> we do it at work too
2014-11-24T00:24:24 < KreAture_> so the software dept can start while hw finishes design
2014-11-24T00:24:43 < KreAture_> that way we get warnings and heads up if stuff sw intended can't be done on the pinout we suggested
2014-11-24T00:26:21 < kakeman> with flat cables that would look ok
2014-11-24T00:26:32 < KreAture_> It is custom length cables
2014-11-24T00:26:34 < KreAture_> crimped
2014-11-24T00:26:39 < kakeman> nice
2014-11-24T00:26:45 < KreAture_> reason is, the fixed wiring is made short and direct
2014-11-24T00:26:53 < KreAture_> rest is long enough to reach anywhere on the stm32 board
2014-11-24T00:26:57 < KreAture_> so I can change anything
2014-11-24T00:27:14 < KreAture_> On other side oif this plank I will be mounting some other stuff
2014-11-24T00:27:26 < KreAture_> there will be some boost converters controlled by the stm32
2014-11-24T00:27:32 < KreAture_> and a lot of sensor channels
2014-11-24T00:27:40 < KreAture_> for temp measurements
2014-11-24T00:27:51 < upgrdman> KreAture_: is that a wide format printer or a vinyl cutter?
2014-11-24T00:28:02 < KreAture_> 3d printer
2014-11-24T00:28:03 < KreAture_> :)
2014-11-24T00:28:14 < KreAture_> It's the start of a new platform to get rid of fucking arduino
2014-11-24T00:28:15 < KreAture_> lol
2014-11-24T00:28:37 < upgrdman> no i mean  http://kreature.org/images/flat/more_room/more_room_1.jpg
2014-11-24T00:28:42 < upgrdman> on the right
2014-11-24T00:28:58 < KreAture_> That is a 24" full photo printer
2014-11-24T00:29:03 < upgrdman> nice
2014-11-24T00:29:08 < KreAture_> The stuff on the wall is from it

2014-11-24T00:30:22 < Steffanx> Tell your rabbit not to get that hay all over the floor.
2014-11-24T00:30:24 < KreAture_> and yes, that uses a LOT of ink
2014-11-24T00:30:31 < KreAture_> Steffanx too late
2014-11-24T00:30:34 < KreAture_> I got two rabbits
2014-11-24T00:30:42 < KreAture_> and the floor is a constant pigsti (rabbit sti)
2014-11-24T00:32:23 < KreAture_> I am going to abuse the dma control in the stm32 for the 3d printer controller btw
2014-11-24T00:32:31 < KreAture_> tested a few sneaky tricks and they work!
2014-11-24T00:32:48 < KreAture_> will be able to do a perfectly synchronous output on all 16 pinns for 8 step and 8 dir pins
2014-11-24T00:33:02 < KreAture_> and I will be able to do a hardware assisted stop in case of endstop triggering
2014-11-24T00:34:23 < kakeman> KreAture_: are you swe, nor, dan?
2014-11-24T00:34:33 < KreAture_> nor
2014-11-24T00:34:43 < zyp> 21:48:47 < KreAture_> it's only if you are doing heavy stuff or 16/32 bit math on a 8 bit mcu that you really gain and see it shrink
2014-11-24T00:34:45 -!- lieron [~lieron@185.54-240-81.adsl-dyn.isp.belgacom.be] has joined ##stm32
2014-11-24T00:34:54 < zyp> so you aren't doing 16/32 bit math?
2014-11-24T00:35:00 < KreAture_> I am
2014-11-24T00:35:04 < KreAture_> heavily
2014-11-24T00:35:13 < KreAture_> which is why in this case a move to 32 bit is a very nice move
2014-11-24T00:35:38 < KreAture_> but a simple system that monitors some io and sends data over serial, will be bigger on stm32 than a 8 bit mcu
2014-11-24T00:36:13 < zyp> why does code density of a simple system that monitors some io and sends data over serial even matter?
2014-11-24T00:36:33 < KreAture_> I never said it does
2014-11-24T00:36:49 < KreAture_> I just found many ppl are surprised that their utterly simple app will not compile in iar kickstarter
2014-11-24T00:36:53 < KreAture_> because it is too big
2014-11-24T00:36:57 < KreAture_> 32k limit
2014-11-24T00:37:14 < zyp> why the fuck would an utterly simple app need 32k?
2014-11-24T00:37:21 < KreAture_> They take a 16k app on 8 bit and compile for 32 bit and it is over 32k and they can't do it
2014-11-24T00:37:33 < KreAture_> zyp because it contains a LOT of data
2014-11-24T00:37:35 < KreAture_> like text
2014-11-24T00:37:41 < KreAture_> for example it is parsing xml
2014-11-24T00:38:08 < zyp> «8 bit» «utterly simple app» «parsing xml»
2014-11-24T00:38:23 < KreAture_> zyp yes that is simple
2014-11-24T00:38:35 < KreAture_> I think you have a different level of complexity in mind
2014-11-24T00:40:40 < KreAture_> I am used to quite complex multithreaded apps on 8 bit systems
2014-11-24T00:40:44 < zyp> well, yes
2014-11-24T00:40:58 < KreAture_> Goal here is to step that up a notch and get something fully fluent on 32 bit
2014-11-24T00:41:02 < KreAture_> :)
2014-11-24T00:41:18 < KreAture_> I am hoping to implement most of the delt aprinter system from scratch
2014-11-24T00:41:20 < zyp> I'm trying to decide what upsets me the most of the fact that you consider parsing xml on a mcu utterly simple, or that you would even do it in the first place
2014-11-24T00:41:47 < KreAture_> I had to do it as the customer demanded xml as commandfile/metafile input format
2014-11-24T00:42:06 < KreAture_> sometimes the customer also demands text protocols
2014-11-24T00:42:10 < KreAture_> I utterly hate those
2014-11-24T00:42:17 < KreAture_> yes, human readable, blah blah blah

2014-11-24T00:42:29 < KreAture_> but debugging is best done in a debugger and it doesn't care about text
2014-11-24T00:42:41 < KreAture_> also, protocols should be tested automatyically
2014-11-24T00:42:47 < KreAture_> not by staring at it
2014-11-24T00:43:04 < mitrax> i'm using eclipse for an STM32 project, with Cross GCC as toolchain and CDT internal builder as current builder, .c files added to the project compile fine, but .cpp files are ignored, i'm not familiar with eclipse, is there a place where to select which extensions should be built?

2014-11-24T00:45:27 < zyp> qyx_, apparently it's utterly simple
2014-11-24T00:46:33 < KreAture_> as long as you have a limited set of symbols you support, and you simply ignore any elements you don't recognize it is quite easy to do
2014-11-24T00:46:41 < qyx_> i would avoid xml even on desktop, because a) it is too verbose b) it is so '90
2014-11-24T00:46:46 < KreAture_> agrreed
2014-11-24T00:46:49 < KreAture_> agreed
2014-11-24T00:47:01 < KreAture_> unfortunately it's a buzzword that refuses to die
2014-11-24T00:47:07 < KreAture_> and customers with money have less sence
2014-11-24T00:47:15 < KreAture_> They follow buzz
2014-11-24T00:49:35 < upgrdman> are square toilets common in .eu?  http://kreature.org/images/cabin/toilet.jpg
2014-11-24T00:50:04 < Steffanx> Not in dutchland
2014-11-24T00:51:24 < qyx_> same here
2014-11-24T00:51:45 < kakeman> what is typical freertos binary size?
2014-11-24T00:51:59 < kakeman> no special shiet just few tasks
2014-11-24T00:53:22 < qyx_> what is typical train power consumtion? no special shit, just few motors and stuff
2014-11-24T00:53:48 < kakeman> :)
2014-11-24T00:54:05 < englishman> five
2014-11-24T00:55:32 < zyp> upgrdman, that's a cabin toilet, not a normal house one
2014-11-24T00:55:45 < upgrdman> o ok
2014-11-24T00:55:52 < kakeman> I think 2MW would do
2014-11-24T00:56:37 < kakeman> The RTOS kernel itself required about 5 to 10 KBytes of ROM space when using the same configuration as stated for the FAQ "How much RAM does FreeRTOS use?".
2014-11-24T00:58:10 < kakeman> it's fun to empty one
2014-11-24T00:58:49 < kakeman> is that dry toilet?
2014-11-24T00:59:02 < kakeman> and composting?
2014-11-24T01:00:25 < KreAture_> upgrdman that is a incindiary toilet
2014-11-24T01:00:44 < upgrdman> your poop in it and drop a match in?
2014-11-24T01:00:50 < qyx_> whats the pipe for then?
2014-11-24T01:00:54 < KreAture_> upgrdman no it ignites by itself
2014-11-24T01:01:08 < KreAture_> it burns sheite
2014-11-24T01:01:10 < KreAture_> :p
2014-11-24T01:01:18 < KreAture_> It's for cabinsd
2014-11-24T01:01:20 < KreAture_> yes
2014-11-24T01:01:20 < kakeman> oh
2014-11-24T01:01:22 < upgrdman> self-igniting poop.... must acquire....
2014-11-24T01:01:27 < kakeman> poopburnier
2014-11-24T01:01:30 < qyx_> i assumed there are multiple cabins stacked on top with single drain pipe
2014-11-24T01:01:30 < KreAture_> where you do not have access to plumbing
2014-11-24T01:01:42 < KreAture_> it's exhaust
2014-11-24T01:01:56 < qyx_> ok, seems reasonable
2014-11-24T01:02:15 < KreAture_> My cabin is by the lake and you are not allowed to have a hole in the ground-type outhouse pooper there as it contaminates the lake
2014-11-24T01:02:35 < KreAture_> http://kreature.org/images/cabin/cabin_02.jpg
2014-11-24T01:03:11 < kakeman> cant you use water cleaner?
2014-11-24T01:03:19 < KreAture_> for poop ?
2014-11-24T01:03:31 < KreAture_> On this one I have a septic tank, but the municipal drains have been extended now so I can hook it up: http://kreature.org/images/cabin/cabin_large.jpg
2014-11-24T01:03:42 < KreAture_> kakeman it contaminates the water so the fish don't like it
2014-11-24T01:03:56 < KreAture_> It's a great lake for sportsfishing
2014-11-24T01:04:18 < KreAture_> and a great place to relax

2014-11-24T01:05:00 < KreAture_> yes
2014-11-24T01:05:01 < KreAture_> too close
2014-11-24T01:05:05 < KreAture_> there are rules about it
2014-11-24T01:05:30 < kakeman> here you cant build that close
2014-11-24T01:05:52 < kakeman> nowhere near that
2014-11-24T01:06:08 < KreAture_> Private land, private lake
2014-11-24T01:06:18 < kakeman> oh
2014-11-24T01:06:21 < qyx_> tsss
2014-11-24T01:06:24 < kakeman> cool
2014-11-24T01:06:26 < KreAture_> Not all mine though, we're a large group
2014-11-24T01:06:35 < KreAture_> and we allow anyone to fish in it
2014-11-24T01:06:49 < KreAture_> You have to pay a licence though
2014-11-24T01:07:29 < KreAture_> we use the money from the licencing to pay for water acidity control, pest/desease checks and we also set out trout
2014-11-24T01:07:54 < KreAture_> basically last years money is used by the next year by setting aside fixed expenses and using the rest to improve the fishing
2014-11-24T01:08:06 < KreAture_> it works very well
2014-11-24T01:08:24 < KreAture_> and creates a quite idyllic situation for relaxation and fun
2014-11-24T01:08:41 < KreAture_> due to the birdlife in the area (some rare birds) motorboats are banned
2014-11-24T01:08:54 < KreAture_> you can sail to your hearts delight though
2014-11-24T01:11:11 < KreAture_> hmm someone asked about sizes
2014-11-24T01:11:36 < kakeman> *sigh* sailboats are expensive
2014-11-24T01:11:50 < KreAture_> usb support, a simple vcp and loopback function, 3 additional threads that simply blink some leds and listen to a button = 59k with optimizing off
2014-11-24T01:12:03 < KreAture_> bss is 20k program is 38k
2014-11-24T01:12:23 < kakeman> 8|
2014-11-24T01:13:03 < kakeman> usb takes most of it?
2014-11-24T01:14:57 < KreAture_> optimizing for size gives 38k total 16k app and 20k bss
2014-11-24T01:15:04 < KreAture_> I think so
2014-11-24T01:15:08  * KreAture_ disables usb thread
2014-11-24T01:15:45 < KreAture_> Hmm, it still includes all the usb stuff unless I make a target for excluding it
2014-11-24T01:15:46 < KreAture_> dang
2014-11-24T01:15:56 < KreAture_> that won't hapen sorry
2014-11-24T01:15:57 < KreAture_> hehe
2014-11-24T01:16:02 < kakeman> ye
2014-11-24T01:16:11 < KreAture_> I assume so though
2014-11-24T01:16:27 < KreAture_> saved 1k by disabeling the usb init and task
2014-11-24T01:16:41 < KreAture_> so rest is taken up by the isr code etc
2014-11-24T01:16:43 < KreAture_> I assume
2014-11-24T01:22:28 < decimad2> things got much simpler since rs232...
2014-11-24T01:23:05 < decimad2> also it's pretty cheap nowadays to deliver a driver for your usb device
2014-11-24T01:24:15 < KreAture_> well
2014-11-24T01:24:22 < KreAture_> I still claim rs232 is superior
2014-11-24T01:24:31 < KreAture_> usb is polled
2014-11-24T01:24:38 < KreAture_> only now with new usb 3 do we have interrupt
2014-11-24T01:24:45 < KreAture_> and even then it sucks
2014-11-24T01:24:52 < KreAture_> drivers fault though
2014-11-24T01:26:32 < decimad2> Sorry, I don't know anything about usb, because I always thought it was some transport medium but it was really hard to get specific information about it. This way it seemed so complex that it's not feasible to use as a one-person show... And then the price for an usb license and the signature for windows drivers...
2014-11-24T01:26:58 -!- mumptai [~calle@brmn-4db764d1.pool.mediaWays.net] has quit [Quit: Verlassend]
2014-11-24T01:27:00 < decimad2> it's like after rs232 they decided that it should only be the big corps
2014-11-24T01:27:38 < zyp> eh, usb is nice
2014-11-24T01:28:13 < kakeman> avoided using usb when found ethernet phy on board
2014-11-24T01:28:57 < KreAture_> zyp I have implemented usb on 8 bit mcu, it is not nice
2014-11-24T01:28:58 < KreAture_> hehe
2014-11-24T01:29:11 < KreAture_> yeah ethernet is ac tually better
2014-11-24T01:29:19 < KreAture_> much less overhead
2014-11-24T01:29:31 < zyp> hah
2014-11-24T01:29:36 < KreAture_> better noe with smarter usb peripherals on mcus's though
2014-11-24T01:29:49 < qyx_> much less overhead? you mean like only 80 bytes or so on every packet?
2014-11-24T01:29:54 < zyp> usb is way simpler than the full tcp/ip stack you'd want on top of ethernet
2014-11-24T01:29:55 < KreAture_> all the annoying ping/pong shit is done
2014-11-24T01:30:00 < KreAture_> I mean cpu overhead qyx_
2014-11-24T01:30:11 < KreAture_> zyp use udp
2014-11-24T01:30:13 < KreAture_> hehe
2014-11-24T01:30:24 < KreAture_> have you seen the 8 bit mcu udp hacks ?
2014-11-24T01:30:44 < qyx_> not many things called "hacks" are usable in reality
2014-11-24T01:30:46 < KreAture_> tiny temperature loggers are easily made that send udp packets to a server with temp data
2014-11-24T01:30:50 < zyp> and I call bullshit on cpu overhead too
2014-11-24T01:30:54 < qyx_> but yes, i have seen bitbanged 10mbit ethernet on avr
2014-11-24T01:30:56 < decimad2> one thing is complexity, the other thing is the implied cost using it on the windows platform...
2014-11-24T01:31:22 < KreAture_> my problem with usb is the onstant signals
2014-11-24T01:31:32 < KreAture_> ethernet allows you to sit much more quietly
2014-11-24T01:31:40 < zyp> how so?
2014-11-24T01:32:12 < KreAture_> usb keeps sending packets
2014-11-24T01:32:14 < KreAture_> all the time
2014-11-24T01:32:19 < KreAture_> at a high rate
2014-11-24T01:32:29 < KreAture_> it has to as you can't send anything untill the host asks for it
2014-11-24T01:32:36 < KreAture_> as a device
2014-11-24T01:32:47 < qyx_> this apply for all halfduplex interfaces
2014-11-24T01:32:49 < qyx_> *to
2014-11-24T01:33:02 < zyp> qyx_, no
2014-11-24T01:33:07 < KreAture_> rs232 is full duplex in most cases
2014-11-24T01:33:08 < zyp> KreAture_, so what?
2014-11-24T01:33:26 < qyx_> ok, contention avoiding can be done in other ways too
2014-11-24T01:33:28 < KreAture_> zyp unit has to service all those usb packets
2014-11-24T01:33:41 < zyp> KreAture_, yes, the usb peripheral does that
2014-11-24T01:33:47 < KreAture_> zyp NOW it does
2014-11-24T01:33:48 < qyx_> but always there is delay or the act of competing for the medium
2014-11-24T01:33:54 < KreAture_> I have been working with usb since 1.1
2014-11-24T01:33:55 < zyp> I'd argue that the plethora of ethernet broadcasts on a common network is much worse
2014-11-24T01:33:57 < qyx_> like can, csma/ca/cd
2014-11-24T01:34:06 < KreAture_> and the mcu's back then did not have any usb peripheral
2014-11-24T01:34:15 < zyp> KreAture_, I don't care about the past, I care about today's hardware
2014-11-24T01:34:28 < KreAture_> zyp and I said so too, that it is very nice with todays hardware
2014-11-24T01:34:37 < KreAture_> you still have lots of driver issues though
2014-11-24T01:34:49 < zyp> nah
2014-11-24T01:34:54 < KreAture_> and windows in particular has a tendency to hang it's usb stack if a unit comes and goes too often
2014-11-24T01:34:56 < zyp> userspace usb is easy
2014-11-24T01:34:57 < kakeman> have you guys used higher speed rs232?
2014-11-24T01:35:06 < KreAture_> kakeman 6 mbit rs232 yes
2014-11-24T01:35:12 < kakeman> nice
2014-11-24T01:35:36 < qyx_> rs232?
2014-11-24T01:35:40 < kakeman> I didn't know it goes that gar
2014-11-24T01:35:43 < zyp> I believe that since win8 a device can even identify itself as a userspace usb device
2014-11-24T01:35:44 < kakeman> far
2014-11-24T01:35:56 < KreAture_> kakeman high yes far no
2014-11-24T01:35:59 < zyp> and even if not, binding to winusb is easy
2014-11-24T01:36:00 < KreAture_> link was only 2ft
2014-11-24T01:36:17 < kakeman> absolute maximum?
2014-11-24T01:36:22 < KreAture_> zyp win8 is useless hehe
2014-11-24T01:36:39 < zyp> KreAture_, not my problem
2014-11-24T01:36:42 < KreAture_> I have NO problem with em adding a new ui, just don't burn the entire old if
2014-11-24T01:37:14 < KreAture_> I'd rather have a root canal than use a os that has the same layout as the system they use to talk to apes
2014-11-24T01:37:38 < kakeman> KreAture_: what you used it for?
2014-11-24T01:37:42 < KreAture_> I didn't
2014-11-24T01:38:07 < KreAture_> but the researchers that teach apes sign language and communication used to use a tablet with a interface looking very very similar to "metro"
2014-11-24T01:38:08 < KreAture_> hehe
2014-11-24T01:38:37 < KreAture_> http://images.gizmag.com/inline/bonobochat.jpg
2014-11-24T01:40:45 < qyx_> ok, on a different topic
2014-11-24T01:40:56 < qyx_> can i use rail-to-rail opamp for high side current sensing?
2014-11-24T01:41:07 < qyx_> it claims to support common mode voltages of up to Vdd+0.3V
2014-11-24T01:41:57 < kakeman> ok so chip supports uart speeds to 6.25Mbps
2014-11-24T01:41:58 < KreAture_> Is it linear at those proximitys
2014-11-24T01:42:10 < zyp> KreAture_, so anyway, that code size you mentioned earlier sounds horribly bloated
2014-11-24T01:42:20 < KreAture_> zyp I think so too
2014-11-24T01:42:21 < kakeman> tranceivers I have seen to 3Mbps
2014-11-24T01:42:43 < qyx_> cannot find anythig saying it is not linear.. linearity is a bit worse at Vdd-1.1V
2014-11-24T01:43:01 < decimad2> what better quality sign is there for an ui than that even apes can use it?
2014-11-24T01:43:16 < zyp> KreAture_, the firmware on the usb board I've been selling consumes around 8k of flash
2014-11-24T01:43:18 < KreAture_> zyp functions in sections was not turned on
2014-11-24T01:43:22 < KreAture_> zyp compiling again
2014-11-24T01:43:44 < KreAture_> zyp it contained the entire usb lib
2014-11-24T01:43:52 < KreAture_> and the entire bsp driver lib
2014-11-24T01:44:06 < KreAture_> now after cleaning sections it is 8.9k
2014-11-24T01:44:07 < KreAture_> !
2014-11-24T01:44:10 < KreAture_> muuuuch better
2014-11-24T01:44:14 < zyp> and I believe I mad a simple dfu bootloader at <3k of flash once
2014-11-24T01:45:31 < KreAture_> zyp sure
2014-11-24T01:46:25 < KreAture_> it is just that you have to remember that a simple app running through a long list of code that is for example 16k words in 8 bit mcu, will, if not on thumb code need to use double sized opcodes
2014-11-24T01:46:55 < KreAture_> thumb is brilliant in that respect though
2014-11-24T01:47:14 < zyp> I thought we were done with thumb vs 8bit that, and were arguing about usb now
2014-11-24T01:47:24 < KreAture_> lol
2014-11-24T01:47:33 < KreAture_> it's not a vs debate
2014-11-24T01:47:36 < zyp> in case this was unclear, the <3k bootloader was running on stm32
2014-11-24T01:47:40 < KreAture_> it's an awareness thing
2014-11-24T01:47:49 < KreAture_> never said you can't do that
2014-11-24T01:47:57 < KreAture_> I have some insanely large bootloaders on 8 bit too
2014-11-24T01:47:59 < KreAture_> 8k one
2014-11-24T01:48:00 < zyp> never implied you did either
2014-11-24T01:48:11 < KreAture_> it had to support entire protocol dictated by customer
2014-11-24T01:48:19 < KreAture_> huge state machine
2014-11-24T01:49:18 < zyp> you did however claim that usb has more cpu overhead than ethernet, and I'd like to call bullshit on that :)
2014-11-24T01:49:29 < KreAture_> call it what you will
2014-11-24T01:49:35 < KreAture_> I have implemented datagrams on both
2014-11-24T01:49:49 < KreAture_> my poor cpu didn't have time to do it's job as it had to service all the nagging from the host
2014-11-24T01:49:59 < KreAture_> no mom, NO data for you!
2014-11-24T01:50:02 < KreAture_> lol
2014-11-24T01:50:14 < zyp> bitbanging usb doesn't count
2014-11-24T01:50:28 < zyp> obviously not bitbanging ethernet either
2014-11-24T01:50:49 < KreAture_> untill we got smarter usb controllers every gamner I knew of used ps2 instead for their mouse as the usb lagged whenever game weas demanding
2014-11-24T01:50:55 < KreAture_> reason was the pc had to poll the mouse
2014-11-24T01:50:58 < KreAture_> on usb
2014-11-24T01:51:19 < KreAture_> now it is still a situation sometimes that mouse can lagg

2014-11-24T01:51:34 < KreAture_> unfortunately the ps2 is gone on most mainboards
2014-11-24T01:51:50 < zyp> fun fact: ps2 is using more time to transfer mouse state than the FS USB polling interval
2014-11-24T01:52:04 < KreAture_> yes but it does so without cpu intervention
2014-11-24T01:52:09 < zyp> so does usb
2014-11-24T01:52:22 < KreAture_> only if you use the later chipsets
2014-11-24T01:52:28 < KreAture_> well later is relative
2014-11-24T01:52:31 < KreAture_> last 4 years
2014-11-24T01:52:31 < KreAture_> hehe

2014-11-24T01:52:55 < KreAture_> and usb still laggs
2014-11-24T01:53:03 < KreAture_> They should have been able to fix that by now
2014-11-24T01:53:06 < KreAture_> hehe

2014-11-24T01:58:13 < zyp> wait, is KreAture_ also norwegian?
2014-11-24T01:58:15 < KreAture_> Steffanx zyp likes to argue, I love to discuss

2014-11-24T01:58:25 < KreAture_> ofcource we must be norwegians
2014-11-24T01:58:39 < zyp> nice, we should grab a beer or something some time

2014-11-24T03:04:23 < KreAture_> no
2014-11-24T03:04:33 < KreAture_> I googled the term
2014-11-24T03:04:38 < KreAture_> bukkake
2014-11-24T03:04:40 < KreAture_> lol
2014-11-24T03:04:58 < KreAture_> the "nicest" hit was "the act of splashing"

2014-11-24T03:05:44 < KreAture_> They are called Transport Partner
2014-11-24T03:05:59 < KreAture_> unfortunately my boss searched for the shortened form of their website

2014-11-24T03:07:05 < upgrdman> FUCK. new usb cable was delivered. i order a usb a -> mini cable. its a fucking a -> FEMALE mini cable.
2014-11-24T03:07:16 < upgrdman> who the fuck uses female mini on a cable
2014-11-24T03:07:22 < GargantuaSauce> wat
2014-11-24T03:07:25 < upgrdman> ya
2014-11-24T03:07:30 < upgrdman> its a mini SOCKET on the cable
2014-11-24T03:07:32 < GargantuaSauce> it's like otg but backwards!
2014-11-24T03:07:35 < upgrdman> ya
2014-11-24T03:07:57 < upgrdman> http://www.amazon.com/gp/product/B005BZNDAS/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
2014-11-24T03:08:07 < upgrdman> the mini on that cable is a socket... like you would find on a pcb
2014-11-24T03:09:06 < GargantuaSauce> http://stores.ebay.com/cmplefree/ this is my preferred source
2014-11-24T03:09:48 < upgrdman> amazon prime can be cheaper. many usb cables are "add on" for prime members, <$2.50
2014-11-24T03:09:53 < upgrdman> plus two day shipping
2014-11-24T03:10:01 < upgrdman> for free
2014-11-24T03:10:03 < KreAture_> so a extension cable
2014-11-24T03:10:04 < KreAture_> hehe
2014-11-24T03:10:23 < upgrdman> KreAture_: not even.
2014-11-24T03:10:28 < KreAture_> haha I bet I can't have 2 day delivery to me
2014-11-24T03:10:36 < KreAture_> not to zyp
2014-11-24T03:10:37 < KreAture_> hehe
2014-11-24T03:10:42 < KreAture_> nor to zyp
2014-11-24T03:10:56 < upgrdman> ya. perk of being in the us i guess.
2014-11-24T03:11:03 < KreAture_> but I will need some cables :)
2014-11-24T03:11:06 < upgrdman> but i hate my neighbor
2014-11-24T03:11:08 < upgrdman> s
2014-11-24T03:11:28 < KreAture_> wonder if he has those nice short usb cables that end up in a usb B socket that can be screwed into a panel

2014-11-24T03:11:48 < KreAture_> I always use such cables to avoid ripping the usb socket off my boards when someone trips in the cable
2014-11-24T03:11:50 < KreAture_> hehe
2014-11-24T03:12:45 < KreAture_> yess!!!!

2014-11-24T03:13:42 < upgrdman> wtf
2014-11-24T03:13:52 < upgrdman> who uses those big ass connectors anymore
2014-11-24T03:13:54 < upgrdman> except printers
2014-11-24T03:14:08 < KreAture_> it's a ruggedness and reliability rhing
2014-11-24T03:14:18 < KreAture_> for a large 3d printer you don't really need a micro connector

2014-11-24T03:23:10 < upgrdman> like bukkake
2014-11-24T03:23:31 < upgrdman> is kakeman a last name?
2014-11-24T03:23:41 < kakeman> certainly not
2014-11-24T03:24:10 < upgrdman> what is it?
2014-11-24T03:24:43 < kakeman> kake was something my friends call me
2014-11-24T03:36:58 < upgrdman> just realized the bukkake comparison might have come off rude. was not intended like that.

2014-11-24T04:36:48 < dongs> attn emeb_mac
2014-11-24T04:37:05 < emeb_mac> looking
2014-11-24T04:38:01 < emeb_mac> bizarre!
2014-11-24T04:38:28 < dongs> thousands of dollars of audiophile circuitry reduced into a single sot23-6 chip
2014-11-24T04:39:33 < dongs> page 7 of manual wow
2014-11-24T04:40:45 < emeb_mac> ya
2014-11-24T04:40:52 < emeb_mac> 100ps
2014-11-24T04:41:00 < dongs> much impress
2014-11-24T04:41:10 < emeb_mac> of course audiophools will not believe
2014-11-24T04:41:19 < dongs> but to see jitter are they triggering on falling and then delaying until rise???
2014-11-24T04:41:25 < emeb_mac> "needz moar toobs"
2014-11-24T04:42:04 < dongs> need to put one of these on everything with PWM output
2014-11-24T04:42:08 < emeb_mac> i assume jitter measurements are based off rising edge only
2014-11-24T04:42:31 < dongs> yeah but if you trigger on jittering rising edge, its not gonna show anything
2014-11-24T04:42:59 < emeb_mac> see pg 8
2014-11-24T04:43:00 < dongs> you wlill only see jitter on next rising edge
2014-11-24T04:43:09 < dongs> right
2014-11-24T04:43:20 < dongs> so they're triggering on one, then measuring on next ?
2014-11-24T04:43:23 < emeb_mac> yes
2014-11-24T04:43:31 < dongs> amaze
2014-11-24T04:43:34 < emeb_mac> no such thing as jitter with respect to self
2014-11-24T04:43:40 < dongs> yeah
2014-11-24T04:44:16 < emeb_mac> it implies there's some programmability, but no detail on that.
2014-11-24T04:44:36 < dongs> i wonder if I should put one of these on hd-sdi receiver im making
2014-11-24T04:44:40 < dongs> on the 27mhz osc output
2014-11-24T04:44:57 < dongs> then i can sell it for 2x price
2014-11-24T04:45:01 < dongs> cuz of less jitter
2014-11-24T04:45:19 < qyx_> hoe much does the thing cost?
2014-11-24T04:45:26 < qyx_> i mean the jitterblocker
2014-11-24T04:45:27 < emeb_mac> super-pro
2014-11-24T04:45:55 < dongs> i dont think its on digieky yet
2014-11-24T04:46:25 < emeb_mac> no
2014-11-24T04:46:40 < dongs> (emeb_mac already checked)
2014-11-24T04:46:41 < emeb_mac> micrel disty stock check shows none
2014-11-24T04:46:49 < emeb_mac> anywhere
2014-11-24T04:46:57 < dongs> its going to be magical
2014-11-24T04:47:01 < dongs> with 100pcs/month production volume
2014-11-24T04:47:02 < emeb_mac> looks like it may need custom programming
2014-11-24T04:47:15 < dongs> for whatever MHz you wanna clean up?
2014-11-24T04:47:25 < emeb_mac> I'll bet it'll be like those SiLabs SI570 parts
2014-11-24T04:47:43 < emeb_mac> $50 in qty 100

2014-11-24T04:47:58 < emeb_mac> bingo
2014-11-24T04:48:18 < emeb_mac> the guys on hydrogenaudio will be all over that shit
2014-11-24T04:50:53 < dongs> surprising, no tokyo maker fail coverage on hackaday
2014-11-24T04:51:04 < dongs> i mean it did suck fucking hard but
2014-11-24T04:56:25 < dongs> oh right
2014-11-24T04:57:14 < emeb_mac> gah - Lua on the esp8266
2014-11-24T04:57:28 < dongs> internet of dicks, its happening
2014-11-24T04:59:47 < englishman> maybe jitterblocker is micrel's answer to audiophiles
2014-11-24T04:59:50 < englishman> and it does exactly nothing
2014-11-24T05:01:52 < dongs> more importantly you can't buy it
2014-11-24T05:02:08 < dongs> more rare = more audiophooley
2014-11-24T05:05:50 < englishman> hello i am new i have some basic rtos questions
2014-11-24T05:06:03 < englishman> at the end of a thread does it excecute again immediately? or at the next tick
2014-11-24T05:06:37 < qyx_> wut
2014-11-24T05:07:16 < englishman> so i create the thread, it starts, it runs
2014-11-24T05:07:16 < dongs> while (1)
2014-11-24T05:07:23 < englishman> does it loop like a wh.
2014-11-24T05:07:24 < englishman> yes.
2014-11-24T05:07:25 < englishman> kthx
2014-11-24T05:07:33 < dongs> i mean, you should have a while (1) in your thread.
2014-11-24T05:07:36 < qyx_> no
2014-11-24T05:07:37 < dongs> doing whatever.
2014-11-24T05:07:38 < qyx_> it doesnt
2014-11-24T05:07:46 < qyx_> as dongs says
2014-11-24T05:08:07 < englishman> so it stops at the end of the thread
2014-11-24T05:08:08 < qyx_> if you let the thread end, it ends
2014-11-24T05:08:10 < englishman> til i start it again
2014-11-24T05:08:13 < englishman> its a task
2014-11-24T05:08:30 < dongs> duno i never looked at what happens with a task if you exit from it
2014-11-24T05:08:34 < dongs> i guess it tears the whole thing down
2014-11-24T05:08:55 < qyx_> in chibios it simply ends
2014-11-24T05:09:02 < dongs> so you can start ait again?
2014-11-24T05:09:04 < qyx_> theres even an api for requesting thread exit
2014-11-24T05:09:18 < qyx_> chThdExitRequest or something like that
2014-11-24T05:09:25 < dongs> retarded naming
2014-11-24T05:09:26 < englishman> or i really should have a while(1) and treat it as another  main()
2014-11-24T05:09:37 < dongs> yes, while(1)
2014-11-24T05:09:40 < englishman> ok
2014-11-24T05:09:42 < qyx_> if you use if(chThdShouldTerminate) or whatever, it exits normally
2014-11-24T05:09:45 < dongs> and you just wait on some flags/queue/wahtever
2014-11-24T05:09:49 < englishman> right
2014-11-24T05:09:54 < dongs> and make it do whatever stuffs.
2014-11-24T05:10:15 < englishman> st uses for (;;) bleh
2014-11-24T05:10:27 < qyx_> if course you can't have for (i = 0; i < 100000000000; i++) like cycles inside for delays
2014-11-24T05:10:40 < qyx_> use wait provided by the rtos
2014-11-24T05:10:42 < dongs> rtos should have a delay thing
2014-11-24T05:10:47 < qyx_> otherwise other tasks will be blocked
2014-11-24T05:10:59 < dongs> or will they?
2014-11-24T05:11:01 < qyx_> no
2014-11-24T05:11:05 < englishman> im dicking with timecube and freertos, its neat
2014-11-24T05:11:15 < dongs> lol timecube, good luck
2014-11-24T05:11:22 < englishman> works fine so far :P
2014-11-24T05:11:23 < qyx_> they will be preempted actually
2014-11-24T05:11:33 < dongs> one buggy version of feertos wasnt enough, so now there's a ST specific variant
2014-11-24T05:11:35 < dongs> wiht even more bugs
2014-11-24T05:11:39 < dongs> so cool

2014-11-24T05:12:16 < englishman> using rtos to blink ws2812b
2014-11-24T05:12:22 < dongs> totally needed
2014-11-24T05:12:29 < emeb_mac> if you can't do it in a big-loop it's not worth doing.
2014-11-24T05:12:34 < Angmar26> why?
2014-11-24T05:12:40 < englishman> to learn rtos shit
2014-11-24T05:13:50 < qyx_> hm, F030 in tsop20
2014-11-24T05:14:04 < dongs> i'm using STM8S003 in tsop20
2014-11-24T05:14:10 < dongs> much cheap
2014-11-24T05:14:47 < qyx_> there is also some cheaper MKL03 thing
2014-11-24T05:15:02 < dongs> yea but fuck feescale
2014-11-24T05:15:12 < dongs> its cheap cuz nobody uses it!!!111
2014-11-24T05:15:48 < qyx_> thinking of using the F030 part to manage solar charger
2014-11-24T05:16:03 < dongs> you should use the one wiht 100ps timer
2014-11-24T05:16:10 < dongs> and MPPT

2014-11-24T06:04:26 < jadew> my remark was in regard to the bbc article

2014-11-24T06:05:14 < jadew> *weight
2014-11-24T06:05:47 < jadew> I suppose they should ban toy guns then, because they clearly don't want to ban real ones

2014-11-24T06:08:02 < jadew> in here, if someone was waving a gun, even an older fellow, you would assume it's a toy first
2014-11-24T06:09:37 < jadew> I guess it's better to hang on to the right to bear arms and be scared of little kids with toy guns
2014-11-24T06:11:02 < GargantuaSauce> they shot a dead boy carrying a gun?

2014-11-24T06:57:26 < dongs> where does a nigga get stick-on touchscreen overlays in china
2014-11-24T07:02:27 < jadew> yeah
2014-11-24T07:03:08 < jadew> I tried it when it was first introduced several years ago (many years ago)
2014-11-24T07:03:21 < jadew> but I have no opinion on it
2014-11-24T07:05:48 < jadew> I really have no opinion on WPF
2014-11-24T07:06:20 < jadew> ms has pumped a lot of time and money into it tho
2014-11-24T07:09:32 < dongs> anything that uses XML for "gui layout" is an instant failure in my book
2014-11-24T07:10:23 < jadew> R2COM, yeah, the js installer
2014-11-24T07:10:41 < jadew> dongs, not necesarily
2014-11-24T07:10:56 < jadew> after all, it's just a description of the layout, what you do with it from there matters
2014-11-24T07:11:40 < jadew> R2COM, for me it just works :)

2014-11-24T07:15:20 < jadew> hah!

2014-11-24T07:15:58 < dongs> waht the fuck is worms
2014-11-24T07:16:04 < jadew> looks nice, never played it
2014-11-24T07:16:11 < jadew> dongs, an awesome game
2014-11-24T07:16:35 < dongs> haha steam
2014-11-24T07:16:35 < dongs> no thanks
2014-11-24T07:16:47 < jadew> what's wrong with steam?
2014-11-24T07:16:54 < dongs> other htan everything?
2014-11-24T07:17:34 < jadew> dongs, I like it because I don't have to care about CDs
2014-11-24T07:17:40 < jadew> license keys, etc
2014-11-24T07:17:44 < dongs> OR OWNING GAMES, APPARENTLY
2014-11-24T07:17:45 < dongs> LOLOLOL
2014-11-24T07:17:56 < dongs> no you dont
2014-11-24T07:17:58 < dongs> nope
2014-11-24T07:17:59 < dongs> nope
2014-11-24T07:18:10 < dongs> fat gabe dies tomrorow / decides to ragequit and shutdown steam, and y oure ufcked
2014-11-24T07:18:13 < dongs> yes you do
2014-11-24T07:18:29 < dongs> steam = internet-connected DRM
2014-11-24T07:18:38 < dongs> and you down own anything you "buy" on there.
2014-11-24T07:24:04 < dongs> um no
2014-11-24T07:26:47 < jadew> I agree, having them online is a huge advantage
2014-11-24T07:27:01 < madist> my copy of tetris has not been patched since 1998
2014-11-24T07:27:15 < jadew> I own tons of games that I have no clue where they are
2014-11-24T07:27:21 < jadew> or if the CDs survived
2014-11-24T07:27:36 < jadew> as for downloadable games, you have to keep track of the license
2014-11-24T07:28:02 < jadew> it's silly compared to having all the games in one place and ready to install with one click on any machine you're on
2014-11-24T07:29:14 < jadew> R2COM, when was this launched?
2014-11-24T07:29:23 < jadew> "clan wars"
2014-11-24T07:29:48 < jadew> is it built on the revolution engine?
2014-11-24T07:30:00 < jadew> (the one they used for worms revolution)
2014-11-24T07:30:05 < jadew> cuz it looks like it and that one sucked
2014-11-24T07:31:22 < jadew> looks interesting from the trailer, but so did revolution
2014-11-24T07:33:12 < dongs> dunno man
2014-11-24T07:33:21 < dongs> 'downloadable' shit has all this 'constant patching' filth too
2014-11-24T07:33:26 < dongs> making programmers lazy as fuck
2014-11-24T07:33:44 < dongs> how many patches do you download for NDS cartridges????????????
2014-11-24T07:33:50 < dongs> thats what I thought
2014-11-24T07:36:15 < englishman> lol steam
2014-11-24T07:36:33 < englishman> gog is only online seller of games you can actually own

2014-11-24T08:09:47 < hesperaux> R2COM, hey i have like 200 games on steam
2014-11-24T08:09:56 < hesperaux> but it's true - you own a license to the game - i've read the TOS
2014-11-24T08:10:08 < hesperaux> I find it very convenient to own the license
2014-11-24T08:10:16 < hesperaux> but they don't guarantee the license for perpetuity
2014-11-24T08:10:19 < hesperaux> it's a best effort

2014-11-24T08:10:53 < hesperaux> R2COM, if you do have your game folder, yes, most of them you can still play with the steam.exe that's installed in offline mode
2014-11-24T08:11:15 < upgrdman> yup
2014-11-24T08:11:28 < hesperaux> oh oh oh
2014-11-24T08:11:39 < hesperaux> upgrdman, did you ask me about zybo before I lost 7.5TB of my personal data last night?
2014-11-24T08:11:50 < upgrdman> hesperaux: yes i did
2014-11-24T08:12:05 < hesperaux> upgrdman, i've barely been able to use it. I was overwhelmed with it when I tried to start. I installed vivado and i was like wtf do i do now
2014-11-24T08:12:13 < upgrdman> ah
2014-11-24T08:12:18 < dongs> upgrdman: super old

2014-11-24T08:13:29 < hesperaux> two raids: raid5 storage, raidz2 backup. Both of them died
2014-11-24T08:13:37 < hesperaux> happened in less than a half hour
2014-11-24T08:13:49 < hesperaux> so BACKUP YOUR SHIT. TWO TIMES
2014-11-24T08:14:28 < dongs> raid5 on what size drives?
2014-11-24T08:14:34 < hesperaux> says in the link
2014-11-24T08:14:56 < hesperaux> i bought another one this month. I was just about to increase the raid level to raid6 on that
2014-11-24T08:14:58 < hesperaux> too late now
2014-11-24T08:15:12 < dongs> raid5 on 2TB is completely useless
2014-11-24T08:15:20 < hesperaux> not completely
2014-11-24T08:15:27 < dongs> like 99% chance it'll die while rebuilding
2014-11-24T08:15:38 < hesperaux> not 99%
2014-11-24T08:15:42 < hesperaux> dongs, I've rebuilt it before without issue
2014-11-24T08:15:48 < hesperaux> and then ran it for a year before this happened
2014-11-24T08:15:56 < dongs> raid5 on 1tb, raid6 on 2tb, beyond that you're fucked so just backup everytihng 3 times
2014-11-24T08:16:09 < hesperaux> but yes, as a rule, raid6 for 2T is good
2014-11-24T08:16:11 < dongs> also fucking shitgate, never again
2014-11-24T08:16:16 < hesperaux> yeah man
2014-11-24T08:16:20 < hesperaux> not a bro
2014-11-24T08:16:31 < hesperaux> much fail. such seagate. :(
2014-11-24T08:16:44 < hesperaux> not pictured is the third seagate 2T that failed earlier
2014-11-24T08:16:51 < hesperaux> i replaced that in slot 2 with the WD Red
2014-11-24T08:17:28 < hesperaux> the 500G western digitals were expected to fail. That's why they were in a raidz2. i pulled them from really old, shitty western digital NAS drives
2014-11-24T08:18:36 < upgrdman> also don't block the damn case vents
2014-11-24T08:18:54 < hesperaux> upgrdman, i did that man. for like 5 days it was blocked. hence, FML
2014-11-24T08:19:01 < hesperaux> this is wisdom everyone
2014-11-24T08:19:11 < upgrdman> ++
2014-11-24T08:19:15 < hesperaux> i bought 700 dollars of shit today to serve as an external backup. when it arrives, i'm going to force online the failed disks and pray I can copy off of that
2014-11-24T08:20:08 < upgrdman> i wonder if hdd manufuckers log temps and deny warranty claims on toasty drives
2014-11-24T08:20:08 < dongs> wait, was this software lunix raid
2014-11-24T08:20:42 < hesperaux> dongs, the raid5 was a megaraid SAS 8888ELP
2014-11-24T08:20:50 < hesperaux> the raid6 backup array was zfsonlinux raidz2
2014-11-24T08:21:04 < hesperaux> all drives presented through the 8888ELP though
2014-11-24T08:21:31 < hesperaux> R2COM, raid1 is a pretty good hedge, but it is not a backup
2014-11-24T08:21:42 < hesperaux> i hate their lights
2014-11-24T08:21:51 < hesperaux> they are extremely bright and distracting/painful
2014-11-24T08:21:58 < hesperaux> lol
2014-11-24T08:22:11 < hesperaux> R2COM, nobody knows how good the 6T drives are yet
2014-11-24T08:23:10 < hesperaux> and to answer your question, I like playing deus ex HR, terraria, starbound, borderlands, elder scrolls, mass effect, FTL, robocraft...
2014-11-24T08:23:31 < hesperaux> raid1 is to keep running when a drive fails
2014-11-24T08:23:53 < hesperaux> since both drives are usually purchased at the same time, have the same running hours, and undergo the same writes/reads, they tend to die simultaneously
2014-11-24T08:24:07 < hesperaux> yes, if the second drive doesn't fail
2014-11-24T08:24:17 < hesperaux> hence, not a backup. backup should be an external array/medium/whatever
2014-11-24T08:24:39 < hesperaux> maybe that will work. you can also buy different brands/models
2014-11-24T08:24:52 < hesperaux> but nothing is certain anymore
2014-11-24T08:25:04 < hesperaux> i like WD. I'm thinking of liking HGST though

2014-11-24T08:30:02 < hesperaux> actually it's owned by WD
2014-11-24T08:30:09 < hesperaux> but the IP they use in there apparently works better lately
2014-11-24T08:30:19 < dongs> so you got HDS5C4040ALE630 ?
2014-11-24T08:30:42 < hesperaux> toshiba recently bought some 3.5" IP from WD iirc

2014-11-24T08:37:07 < dongs> damn
2014-11-24T08:37:08 < hesperaux> someone told me toshiba makes good drives now - i have no idea anymore
2014-11-24T08:37:29 < dongs> wtf, 128m cache
2014-11-24T08:38:05 < dongs> On March 8, 2012, Western Digital (WD) acquired Hitachi Global Storage Technologies for $3.9 billion in cash and 25 million shares of WD common stock valued at approximately $0.9 billion.
2014-11-24T08:38:09 < dongs> ok, so WD bought them BUT
2014-11-24T08:38:17 < dongs> To address the requirements of regulatory agencies, in May 2012 WD divested to Toshiba assets that enabled Toshiba to manufacture and sell 3.5-inch hard drives for the desktop and consumer electronics markets.
2014-11-24T08:38:19 < hesperaux> yep
2014-11-24T08:38:22 < hesperaux> saw that
2014-11-24T08:38:31 < dongs> then got sold back to toshiba?
2014-11-24T08:38:33 < dongs> so... who knows
2014-11-24T08:38:40 < hesperaux> it was becasue competition was a bad bad thing and the SEC or wahtever raged
2014-11-24T08:38:51 < hesperaux> it doesn't say WD can't still use the IP
2014-11-24T08:38:58 < hesperaux> it's possible they sold it with rights
2014-11-24T08:39:33 < dongs> anyway
2014-11-24T08:39:35 < dongs>  ibought the WD purple thing
2014-11-24T08:39:39 < dongs> cuz it was "24h spin rated"
2014-11-24T08:39:47 < dongs> cuz its for DVR use or whatever
2014-11-24T08:39:52 < hesperaux> yeah, targetted for sequential access
2014-11-24T08:40:03 < hesperaux> but it still spins down
2014-11-24T08:40:15 < dongs> why would it
2014-11-24T08:40:23 < hesperaux> it spins down when it's not being used
2014-11-24T08:40:31 < dongs> even with power management off?
2014-11-24T08:40:33 < hesperaux> so do the Reds
2014-11-24T08:40:36 < hesperaux> not sure
2014-11-24T08:40:46 < hesperaux> in my sas enclosure i think my reds spin all the time, but it's kinda hard to tell
2014-11-24T08:40:56 < dongs> in windows i always have drive spindown  time set to never
2014-11-24T08:41:09 < hesperaux> heh
2014-11-24T08:41:11 < jpa-> you can set the spindown time with some WD tools
2014-11-24T08:41:18 < hesperaux> jpa-, on linux?
2014-11-24T08:41:27 < hesperaux> and not when they are connected througha  sas raid card
2014-11-24T08:41:29 < jpa-> yes, though it requires reboot
2014-11-24T08:41:43 < dongs> well thats a showstopper
2014-11-24T08:41:48 < dongs> lunix, rebooting?
2014-11-24T08:41:49 < dongs> plzzzzz
2014-11-24T08:41:50 < jpa-> dunno about raid cards, but the setting is stored on the drive so you can set it once and forget
2014-11-24T08:41:53 < dongs> gotta have that 1337 days uptime
2014-11-24T08:41:59 < jpa-> i know, right?
2014-11-24T08:42:01 < hesperaux> jpa-, ok, so i could take it out and set it
2014-11-24T08:42:06 < hesperaux> dongs, lol
2014-11-24T08:42:10 < dongs> here's what I show to unwashed lunix dweebs
2014-11-24T08:42:12 < dongs> wehn they talk about uptime
2014-11-24T08:42:12 < dongs> \\dtvcap has been up for: 1830 day(s), 1 hour(s), 3 minute(s), 59 second(s)
2014-11-24T08:42:17 < dongs> ^ windows XP professional
2014-11-24T08:42:18 < dongs> thank you.
2014-11-24T08:42:22 < jpa-> i have like a million load cycles and counting on my wd green because i don't want to reboot my server
2014-11-24T08:42:23 < hesperaux> xD
2014-11-24T08:42:45 < hesperaux> not rebooting a linux system usually indicates bad "sysadminship"
2014-11-24T08:42:46 < dongs> do lunix smart tools even properly show shit
2014-11-24T08:42:58 < dongs> i remember like a decade ago it would just showe mostly randoml trash for smart data
2014-11-24T08:43:07 < hesperaux> depends onthe drive actually
2014-11-24T08:43:18 < jpa-> lul what, are you claiming that the linux box in the corner of my room is not administrated in a professional way?!?
2014-11-24T08:43:19 < hesperaux> if the drive is in the database, yes, but i've never been able to interpret what I see very well
2014-11-24T08:43:35 < hesperaux> jpa-, just that it never gets fully updated
2014-11-24T08:43:55 < jpa-> yeah, too lazy to care
2014-11-24T08:43:58 < akaWolf> jpa-: you need a reboot after new kernel installed, at least
2014-11-24T08:44:02 < jpa-> i'll just call it a honeypot
2014-11-24T08:44:15 < hesperaux> more like a pot
2014-11-24T08:44:20 < hesperaux> honeypot has a desirable resource shared out

2014-11-24T08:48:53 < akaWolf> $900
2014-11-24T08:48:54 < dongs> what if the helium leaks out.
2014-11-24T08:49:02 < hesperaux> i think you can get it re-inserted
2014-11-24T08:49:19 < dongs> wait
2014-11-24T08:49:24 < dongs> i think tehy're doing it wrong
2014-11-24T08:49:27 < dongs> they should do  vacuum
2014-11-24T08:49:28 < dongs> not helium
2014-11-24T08:50:00 < hesperaux> helium is lighter than air
2014-11-24T08:50:04 < hesperaux> i think that's a factor
2014-11-24T08:50:10 < hesperaux> but i agree
2014-11-24T08:50:15 < hesperaux> a vacuum would cause 0 friction
2014-11-24T08:50:21 < hesperaux> but how would heat escape, dongs?
2014-11-24T08:50:26 < hesperaux> that's a problem there
2014-11-24T08:50:37 < hesperaux> it'd have to travel through the metal, much fewer paths for cooling
2014-11-24T08:52:48 < hesperaux> the disks need convective cooling
2014-11-24T08:54:08 < jpa-> wouldn't most of the friction be from bearings and not the air?
2014-11-24T08:54:17 < hesperaux> yes
2014-11-24T08:54:26 < jpa-> and wouldn't vacuum cause bearings to jam?
2014-11-24T08:54:26 < hesperaux> so removing the air probably would cause more harm than good
2014-11-24T08:54:33 < hesperaux> i don't know about that
2014-11-24T08:54:54 < jpa-> http://en.wikipedia.org/wiki/Vacuum_cementing
2014-11-24T08:55:20 < hesperaux> INTERESTINGLY INTERESTING
2014-11-24T08:56:21 < hesperaux> dongs gave up on us
2014-11-24T08:57:00 < dongs> yeah i dont really give a shit, im just trolling and loading dicknplace for tomrorw
2014-11-24T08:57:03 < dongs> :)
2014-11-24T08:57:36 < englishman> maybe the helium is to reduce weight
2014-11-24T08:57:55 < dongs> totally
2014-11-24T08:58:12 < madist> englishman: helium is there to reduce friction losses.

2014-11-24T11:30:58 < mitrax> gaaah, i can't get eclipse to compile .cpp files when using the gcc cross compiler / linker and CDT, only .c files in the projects get compiled, any idea?
2014-11-24T11:38:04 < zyp> I can't help you otherwise than suggesting «don't use eclipse»
2014-11-24T11:38:34 < mitrax> ahahah
2014-11-24T11:38:51 < mitrax> yeah that's probably a good advice :) it's driving me mad

2014-11-24T11:43:38 < zyp> what pid?

2014-11-24T11:51:25 < zyp> oh, right
2014-11-24T11:55:46 < mitrax> zyp: what IDE do you recommend? (preferably a free one with debugging capability) :p
2014-11-24T11:55:59 < dongs> does that even exist
2014-11-24T11:56:17 < zyp> mitrax, none
2014-11-24T11:56:18 < dongs> if you insist on gcc, crossworks personal license is $150
2014-11-24T11:56:24 < dongs> and things there work
2014-11-24T11:56:37 < dongs> or else you can dick endlessly with gcc/gdb
2014-11-24T11:56:39 < zyp> mitrax, personally I prefer vim for code editing and gdb for debugging
2014-11-24T11:56:43 < dongs> pfft
2014-11-24T11:59:11 < dongs> how do you crossreference through all that C++ ode
2014-11-24T11:59:12 < dongs> code
2014-11-24T11:59:16 < dongs> and do completion and shit
2014-11-24T11:59:19 < dongs> with >vim<
2014-11-24T11:59:23 < dongs> i fucking hate typing

2014-11-24T12:00:00 < zyp> dongs, and I fucking hate clicking around
2014-11-24T12:00:08 < dongs> nobody's forcing you to
2014-11-24T12:00:34 < akaWolf> in the most IDE's there are exist many hotkeys
2014-11-24T12:00:51 < akaWolf> in Qt Creator, for example, exist "fake vim" mode
2014-11-24T12:01:15 < dongs> yeah i mean, i dont mind vim for looking at code
2014-11-24T12:01:18 < dongs> and quick hacks
2014-11-24T12:01:26 < dongs> but i just cant imagine a project with > 10 source files managed by VIM alone
2014-11-24T12:01:39 < dongs> you're not gonna remember every function signature etc in it
2014-11-24T12:01:41 < akaWolf> :)
2014-11-24T12:02:03 < akaWolf> yeah, there I'm agree with dongie
2014-11-24T12:02:22 < dongs> akaWolf: btw, re: our hal discussion
2014-11-24T12:02:30 < akaWolf> and?
2014-11-24T12:02:50 < mitrax> actually i have visual studio & wingdb which supposedly supports debugging through openOCD, i should give that a try
2014-11-24T12:03:06 < akaWolf> VS is pretty good
2014-11-24T12:03:40 < dongs> akaWolf: stuff like gpioHi(port, pin) vs GPIOFactory *gp; HAL->GetGPIOFactory(&gp); GPIOPort *p = gp->GetGPIOPort(PORT_A); p->SetPin(GPIOFactory->GetPin(10), HIGH);
2014-11-24T12:04:05 < akaWolf> are you about overhead?
2014-11-24T12:04:11 < dongs> of course I wouldn't fill sores with PORTB->ODR = 1<<10; everywehre
2014-11-24T12:04:22 < dongs> so I will have a pinchange etc functions/macros
2014-11-24T12:04:27 < dongs> but not insane javashit like the latter.
2014-11-24T12:05:03 < akaWolf> it's a not javashit, just ony example of realisation
2014-11-24T12:05:17 < dongs> but its overly verbose
2014-11-24T12:05:19 < akaWolf> I think, it can be written in more different ways
2014-11-24T12:05:26 < dongs> and unnecesary
2014-11-24T12:05:37 < akaWolf> which will be easy to use
2014-11-24T12:09:40 < akaWolf> gpioHi(port, pin) -- even this can be a soft HAL...

2014-11-24T14:33:49 < jpa-> sure
2014-11-24T14:36:12 < decimad> then let's do that... i wonder how far the rc can be trimmed... and at which rate it might change... maybe ptp will provide updates quickly enough that you don't need an external oscillator anymore

2014-11-24T14:38:53 < jpa-> jitter is probably a bigger problem than stability
2014-11-24T14:39:40 < decimad> well, I will get ptp running either way, I was just wondering... Maybe one can live with the jitter in certain applications
2014-11-24T14:39:50 < dongs> like: all of them
2014-11-24T14:40:25 < karlp> nice atari cart dongs :)
2014-11-24T14:47:46 < jpa-> sure, there are many applications for which the internal RC is just fine

2014-11-24T15:11:57 < decimad> jpa-: I mean it this way: if I can make the hsi precise and stable through ptp, then only the applications that need precision at the jitter level (whatever that may be) would suffer

2014-11-24T15:14:56 < decimad> but I don't know if it's generally a good idea to play with the system clock at runtime...
2014-11-24T15:17:27 < dongs> perfectly fine
2014-11-24T15:17:33 < dongs> you can save a lot of battery with that, too
2014-11-24T15:18:19 < decimad> I feared stability problems...
2014-11-24T15:18:27 < dongs> ? its designed to be configurable
2014-11-24T15:18:32 < dongs> when you first power up, you're on HSI anyway
2014-11-24T15:18:38 < dongs> until you're done wiht init asm
2014-11-24T15:18:43 < dongs> and into SystemInit or so, whatever
2014-11-24T15:19:11 < decimad> well, say I'm running on pll... i will need to fall back to hsi or direct hse and then reconfig pll and then back to pll, right?
2014-11-24T15:19:19 < dongs> yep
2014-11-24T15:19:31 < decimad> can i change the hsi trimming while it drives the pll?
2014-11-24T15:19:55 < dongs> you can change whatever registers allow you to do, if datasheet/rm says you can change those while pll is on then yes
2014-11-24T15:21:16 < decimad> well, they don't note I can't there... but that could destability the pll? need to test probably
2014-11-24T15:23:14 < decimad> well anyways, need to get the 168MHz going... don't want to to bind to chibios hal...
2014-11-24T15:25:12 < dongs> st has .xls for download that dumps systemE_stm32f4.c
2014-11-24T15:25:25 < dongs> you can just generate that once, then look at clock configure shit and pull just the register writes.
2014-11-24T15:25:32 < dongs> i think its sgonna be like ~10 lines of writes total
2014-11-24T15:27:08 < jpa-> pll stability while trimming the HSI is a good question
2014-11-24T15:35:44 < dongs> hmmmm
2014-11-24T15:35:53 < dongs> itead found some 150nH 0402 coils

2014-11-24T16:10:40 < decimad> well the writes are not the problem... it's the calculation of the values at compile time that is the fun ;)
2014-11-24T16:13:19 < zyp> doesn't the datasheet say that you can't run at the full 168 MHz from HSI?
2014-11-24T16:13:32 < dongs> why not?>
2014-11-24T16:14:49 < zyp> I might be thinking of something else, hang on, I'll try looking it up
2014-11-24T16:19:52 < zyp> ok, apparently I'm thinking of a different chip, and I don't remember which
2014-11-24T16:20:14 < decimad> I could imagine it's hard to guarantee staying <= 168MHz when the oscillator is +-1%
2014-11-24T16:21:28 < decimad> then again it's hard with any real oscillator... they should've stated 168+1% as max ;)
2014-11-24T16:22:14 < decimad> I'm running on HSE for the time being btw, so it's no issue
2014-11-24T16:26:14 < dongs> zyp: F1 canm only go to 64mhz on hsi
2014-11-24T16:26:37 < dongs> because hsi clock input before pll is /2
2014-11-24T16:26:42 < dongs> and max multiplier is 16 or someshit

2014-11-24T17:38:01 < rewolff1> hespereaux: The "99% chance it will die while rebuilding" has more truth to it than you think. (I hate to agree with dongs, but sometimes you have to... :-) )
2014-11-24T17:38:31 < rewolff1> A standard raid-controller will mark-a-disk-as-bad when it encounters a single unreadable block.
2014-11-24T17:39:31 < rewolff1> So what often happens is that one disk dies "for good", and that when you insert the new drive, or activate the hot spare (automatically), the rebuild will find a few bad blocks on one or more of the remaining drives.
2014-11-24T17:40:23 < rewolff1> 99.9% of your data is "still there", but the raid controller won't let you get at it....
2014-11-24T17:40:49 < rewolff1> gimme a call if you need it recovered (for a price. :-) )
2014-11-24T17:49:47 < decimad> did you ever use any unusual oscillator and target clock combination that you can still remember?

2014-11-24T18:22:10 < GargantuaSauce> nope
2014-11-24T18:25:18 < decimad> Hehe, nice. But sine waves? I had expected exp-sawtooths?
2014-11-24T18:26:18 < GargantuaSauce> the fact that i have a 50mhz scope MAY have been a factor
2014-11-24T18:26:39 < gxti> certainly.
2014-11-24T18:27:51 < decimad> next time i will write sawteeth...
2014-11-24T18:31:55 < upgrdman> why sawtooth? wouldn't slew rate limit rising and falling slopes?
2014-11-24T18:32:51 < GargantuaSauce> yeah it'd have been pretty round in any case
2014-11-24T18:32:56 < decimad> exp-sawteeth
2014-11-24T18:33:27 < decimad> as in the normal rc-toggle curves... or am I mistaken?
2014-11-24T18:34:42 < upgrdman> i would expect decay to be like cosine, since it takes times for the transistor to turn on/off
2014-11-24T18:35:23 < gxti> all of that is quite hard to see with a 50mhz scope.
2014-11-24T18:35:34 < gxti> so it's not surprising that it would just look like a sine wave.
2014-11-24T18:35:43 < upgrdman> true
2014-11-24T18:38:05 < decimad> yeah, the rise and fall times + differential resistance... my understand was mistaken, since it assumed the load current to be the limiting factor
2014-11-24T18:41:30 < upgrdman> shit. how long does it take for fpga code synthesis? added a video memory module to my code, hit synthesize, its been like 20 minutes
2014-11-24T18:41:51 < upgrdman> i guess all my small shit before was small enough to syn in under a minute

2014-11-24T19:22:11 < kakeman> are dividers/multipliers at their limit values?

2014-11-24T19:54:17 < TheSeven> zyp: on the stm32 uart it replaces one
2014-11-24T19:54:34 < TheSeven> if you want 8 bit + parity, you have to configure the uart for 9 data bits
2014-11-24T19:54:40 < TheSeven> kinda weird, but that's how it is
2014-11-24T19:54:59 < TheSeven> managed to sort that out though, something was corrupting the reg and setting the parity enable bit
2014-11-24T19:55:05 < TheSeven> but now I have a different problem
2014-11-24T19:55:24 < TheSeven> the SBK bit generates a minimal break char (just the first of the two stop bits missing)
2014-11-24T19:55:30 < TheSeven> but I need a longer one..
2014-11-24T19:55:43 < TheSeven> guess I'll have to use GPIO mode changes to implement that?

2014-11-24T22:02:46 < decimad> well, so my clock init doesn't work
2014-11-24T22:03:42 < decimad> my reg constants look like this basically... volatile uint32& reg = foo_func<0xFOOOFOOO>();
2014-11-24T22:04:43 < decimad> so my suspicion is, that this will be initialized during global initialization after the clocks are to be set during debug builds^^

2014-11-24T23:25:10 < decimad> it must have something to do with the function call there... during debug it will probably not be optimized out and when doing "step" over, this gdb plugin seems to set breakpoints right after the call... this together with the change in flash wait states seems to bring everything down

2014-11-25T00:12:41 < zyp> oh, and I have to admit you have some cool ideas
2014-11-25T00:12:56 < zyp> I'll make sure to steal the ones that have actual practical benefit later
2014-11-25T00:13:58 < zyp> by the way, have you seen my «use template specialization for ISRs» trick?
2014-11-25T00:14:29 < zyp> ref. http://cgit.jvnv.net/laks/tree/interrupt/interrupt.h#n145
2014-11-25T00:15:53 < decimad> what about using reg32_t = volatile uint32_t ;)
2014-11-25T00:21:01 < decimad> zyp: but seriously... I guess there's a master-handler somewhere that dispatches from the table? or am i missing any trick there?

2014-11-25T00:22:29 < decimad> zyp: reinterpret_cast<void (*)(void*)>(f) this cast might prove to be "illegal" in the general case
2014-11-25T00:23:14 < zyp> disregard that, that's some second level magic
2014-11-25T00:23:14 < decimad> zyp: but probably works on most compilers without virtual base classes and stuff...
2014-11-25T00:23:37 < zyp> I'm referring to lines 145-149
2014-11-25T00:24:27 < zyp> I'm not even using the mfp magic stuff anymore, it was an idea that turned out to not be that great in practice

2014-11-25T00:26:26 < zyp> also, why wouldn't it work on polymorphic classes? f is known at execution time, so there's nothing to prevent it from pulling the correct function addr from the vtable of f
2014-11-25T00:26:46 < zyp> and the ABI for virtual functions is the same as for normal functions
2014-11-25T00:27:29 < zyp> (why would ISR member functions even be virtual though?)

2014-11-25T00:29:30 < zyp> what?
2014-11-25T00:29:36 < zyp> of course you can specialize functions
2014-11-25T00:29:47 < decimad> c++11 added that?

2014-11-25T00:30:05 < zyp> no? that's been since forever
2014-11-25T00:30:13 < zyp> http://cgit.jvnv.net/laks/tree/interrupt/interrupt.cpp
2014-11-25T00:30:23 < zyp> there's the defaults
2014-11-25T00:31:26 < mitrax> it's partial specialization of template functions that's not allowed :)
2014-11-25T00:31:40 < zyp> ah, yes, that is correct
2014-11-25T00:32:35 < zyp> hmm
2014-11-25T00:33:00 < zyp> I should clean up the lib some time, it's awkward to show off the nice parts when it's full of experiments gone bad :)
2014-11-25T00:33:53 < zyp> http://cgit.jvnv.net/laks/tree/os/pool.h <- here's smartpointers done wrong
2014-11-25T00:34:09 < decimad> oh yeah... I always wanted partial specialization on functions when I was working on such stuff, that must have broadened the rule in my head ;)
2014-11-25T00:34:50 < decimad> great, unlearned wrong knowledge... always good
2014-11-25T00:36:21 < decimad> so yeah, you specialize the function template in some compilation unit and it will be referenced... that's cool... will borrow that
2014-11-25T00:36:37 < zyp> yeah
2014-11-25T00:37:10 < zyp> it's a replacement for having plain function names for ISRs, and the benefit is that you get error checking
2014-11-25T00:37:27 < mitrax> zyp: btw i followed your advice and said farewell to Eclipse... i'm using VS along with gcc, a custom makefile and a wingdb plugin... turns out to be much better :p
2014-11-25T00:37:30 < zyp> you can only specialize on members of the two enums that's declared
2014-11-25T00:38:01 < zyp> mitrax, glad to hear it
2014-11-25T00:38:23 < decimad> is there a plugin that would update the makefiles?
2014-11-25T00:38:25 < zyp> mitrax, if you ever get tired of writing makefiles, I'd also suggest having a look at scons
2014-11-25T00:38:42 < mitrax> decimad: yeah, wingdb does that
2014-11-25T00:39:27 < decimad> well if there is any way I can get VS IDE and gcc compiler together... i will want it
2014-11-25T00:40:21 < decimad> sick of disappearing debug buttons, keys that suddenly won't work anymore in the editor etc...
2014-11-25T00:40:29 < zyp> http://cgit.jvnv.net/arcin/tree/SConstruct <- this is how one of my project build files look, building three firmwares
2014-11-25T00:40:55 < zyp> and I don't really mind hand editing that :)
2014-11-25T00:42:33 < mitrax> decimad: have a look at wingdb, it's rather cheap (<$90), i bought it two years ago for doing some remote linux debugging, and the new version has support for baremetal dev and openOCD, there's a 30 day trial with full functionallity
2014-11-25T00:43:31 < decimad> oh, I think I had a look at it when I was thinking about going atmel cortex m4...
2014-11-25T00:44:06 < decimad> it looked nice... but too expensive for my first steps... maybe I will hate this stuff ;)
2014-11-25T00:44:26 < decimad> because, if there's a problem I can't solve with templates...
2014-11-25T00:45:23 < decimad> I have a  src_clock -> target_clock rcc clock template now that will find the closest combination of parameters... how great is this!
2014-11-25T00:46:25 < decimad> I only have to say: rcc::config_hse< 8000000, 168000000 >(); Or any other combination that works... ;)
2014-11-25T00:46:42 < mitrax> eheh good idea
2014-11-25T00:48:58 < mitrax> gah i wish the stm32 cube directory structure were cleaner
2014-11-25T00:50:29 < mitrax> everything is spread in a bunch of different dirs with names that are inconsistent
2014-11-25T00:50:41 < decimad> so visual studio pro comes for free now, now you only have to pay for replacing the compiler... hehe

2014-11-25T00:55:47 < decimad> Didn't notice any slowness that would hold me back... plus intellisense got much better
2014-11-25T00:56:13 < decimad> which you don't care about, if you're having visual assist ;)
2014-11-25T00:56:25 < KreAture_> decimad is it a template or a function if it can find the closest...
2014-11-25T00:56:35 < KreAture_> a template just sets up how something looks doesn't it ?
2014-11-25T00:56:48 < decimad> KreAture_: templates are turing complete
2014-11-25T00:56:53 < KreAture_> or an outline of something
2014-11-25T00:57:03 < decimad> you can calculate anything integral with them
2014-11-25T00:57:11 < KreAture_> decimad they they should stop calling em templates and start calling em setup scripts
2014-11-25T00:57:46 < decimad> Maybe... Do you know D's mixins?
2014-11-25T00:58:19 < decimad> You can basically run constexpr functions that generate strings which are then used as code ;)

2014-11-25T02:24:19 < upgrdman> anyone here generated vga signal with a uc or fpga? during the blanking intervals, are the R/G/B pins ignored, or do they need to be driven to a specific value?

2014-11-25T02:30:11 < zyp> upgrdman, I've done that, but I don't know
2014-11-25T02:30:21 < qyx_> same here
2014-11-25T02:30:33 < qyx_> it was on 68hc11
2014-11-25T02:31:07 < qyx_> wasnt even vga, just b/w composite
2014-11-25T02:31:58 < zyp> I'm not sure how cheaply constructed crt monitors could be, but it's not completely improbable that the beam remains on during retrace, which means you want to send black
2014-11-25T02:32:24 < upgrdman> k
2014-11-25T02:32:31 < upgrdman> i will be testing with an lcd
2014-11-25T02:32:41 < upgrdman> but will keep that in mind if buggy
2014-11-25T02:32:41 < zyp> though, they might as well gate the signal during retrace and force it to black

2014-11-25T02:32:58 < zyp> an lcd will probably simply ignore it
2014-11-25T02:33:24 < upgrdman> is hdmi a bitch to do (with an fpga) ? like >100MHz or complex state diagram?
2014-11-25T02:33:28 < zyp> but I guess it might mess up auto adjust
2014-11-25T02:33:53 < zyp> auto adjust probably also expects it to remain low outside visible portion, to detect edges
2014-11-25T02:34:12 < zyp> heh
2014-11-25T02:36:31 < zyp> I'm not sure how slow HDMI could run, but HDMI 1.0 had a max baudrate of 1650 MHz
2014-11-25T02:37:06 < dongs> upgrdman: nobody sane does HDMI with FPGA
2014-11-25T02:37:16 < dongs> there are supe cheap hdmi transmitter and receiver ICs

2014-11-25T02:54:29 < KreAture> Classic norwegian -> english translation
2014-11-25T02:54:58 < KreAture> it was supposed to be "It is absolutely not possible - but let it happen."
2014-11-25T02:55:21 < KreAture> In norwegian "Det går over hodet ikke and, men la det skje."

2014-11-25T11:28:54 < decimad2> So to get this straight: There's my mcu sporting jtag or some vendory specific connection. Even for jtag the actually content is vendor specific. Then there's a debug probe that will connect to the hardware port and do the communication with the device, relaying stuff to some common interface like usb. Then there's openocd that basically serves as a debug abstraction layer that serves gdb serial streams on one side and probe
2014-11-25T11:28:54 < decimad2> specific communication on the other side (ie. a driver) to which you connect by a gdb remote session?

2014-11-25T11:31:56 < karlp> decimad2: pretty much
2014-11-25T11:31:58 < decimad2> whereas jlink gdb server is a "real" gdb server that is not split up into gdb and a remote process

2014-11-25T11:32:22 < karlp> no, jlink gdb server just builds the gdbserver and the debug probe into the same piece
2014-11-25T11:32:30 < karlp> just like black magic probe or similar
2014-11-25T11:33:15 < decimad2> why didn't they just provide a remote backend? seems like easier to support
2014-11-25T11:33:27 < karlp> maybe,
2014-11-25T11:33:36 < decimad2> anyways, it works either way
2014-11-25T11:34:40 < decimad2> Is the protocol between jlink and jlink gdbserver open? I wonder how openocd can talk to the hardware-probe
2014-11-25T11:39:16 < dongs> it shouldn't be
2014-11-25T11:39:21 < dongs> but some opensores dicks wasted tiem to RE it
2014-11-25T11:39:34 < dongs> if youre using jlink you might as well use htier gdbserver cuz it simply works
2014-11-25T11:40:02 < decimad2> I do, but people where talking about wingdb yesterday and it uses openocd
2014-11-25T11:44:05 < dongs> openocd is gdbserver.

2014-11-25T13:11:05 < decimad2> There's boost units
2014-11-25T13:11:07 < PaulFertser> decimad2: you wouldn't be able to mix up the values while passing them around, I guess.
2014-11-25T13:11:17 < decimad2> I think that might prove more helpful
2014-11-25T13:11:32 < decimad2> A pure typedef doesn't provice type safety
2014-11-25T13:12:14 < PaulFertser> That's unfortunate, but splint catches those, isn't that enough?
2014-11-25T13:13:37 < PaulFertser> Also, suppose you have ADC readings from different ADCs having different references. All of them have the same "unit" but are actually different enough to warrant a dedicated type probably?
2014-11-25T13:14:02 < PaulFertser> Also, few people are ready to use Boost for embedded projects.
2014-11-25T13:15:01 < PaulFertser> What are the alternative approaches anyway? Doing firmware in Ada? Or probably restricting oneself to Atom DSL (or Copilot)?
2014-11-25T13:16:39 < PaulFertser> And there's no valgrind to catch runtime nastiness.
2014-11-25T13:20:29 < GargantuaSauce> i feel like language-level unit analysis would be excruciating
2014-11-25T13:22:31 < PaulFertser> Many people are counting on type safety when doing desktop applications in modern languages, they seem happy enough.
2014-11-25T13:22:39 < dongs> PaulFertser: you mean typedef'ing a uintXX into s ome other name?
2014-11-25T13:22:44 < PaulFertser> dongs: yep
2014-11-25T13:22:47 < dongs> nope, fuck that
2014-11-25T13:22:53 < dongs> cuz you see int16_t you know exactly whats inside
2014-11-25T13:22:59 < dongs> you see velocity_t you dont know until you look it up
2014-11-25T13:23:24 < PaulFertser> dongs: why would you care? You've chosen the right storage size ones when typedef'ing, done.
2014-11-25T13:23:40 < dongs> PaulFertser: when youre doing math or assigning stuff or ???
2014-11-25T13:24:06 < dongs> so if it is a uint for exazmple you dont assign negative shit to it
2014-11-25T13:24:39 < PaulFertser> dongs: I had experience finding bugs in my own program due to integer overflows. The fact my vars were uint8_t or uint16_t didn't help as I wasn't using hungarian notation.
2014-11-25T13:25:44 < PaulFertser> dongs: in fact you raise another important question: how to reliably prevent integer over- and underflows etc.
2014-11-25T13:27:38 < GargantuaSauce> i feel like any nontrivial math should be reasoned out in documentation and the code should follow directly from it
2014-11-25T13:27:48 < GargantuaSauce> so you know all the ranges a priori and the issue never comes up
2014-11-25T13:28:21 < PaulFertser> This sounds easier than it actually is, IMHO.
2014-11-25T13:28:22 < dongs> PaulFertser: well if you used a proper IDE you'd know the variable type while hovering over it or something
2014-11-25T13:28:25 < PaulFertser> Anyone doing it?
2014-11-25T13:29:30 < GargantuaSauce> yes, though i don't usually have the discipline to permanently record the whiteboard or notebook scribblings alongside the code
2014-11-25T13:29:38 < PaulFertser> dongs: right, but that's still not enough to ensure calculations are always correct. I get your point, you want less type indirections to be able to mentally reason about expressions regarding storage capacity.
2014-11-25T13:29:38 < GargantuaSauce> which admittedly defeats the purpose
2014-11-25T13:29:57 < PaulFertser> Yep, so there should be another method, more reliable and verifiable.
2014-11-25T13:30:22 < GargantuaSauce> something like a matlab/octave prototype of each function might be a useful approach
2014-11-25T13:30:47 < dongs> surely thats only for pros
2014-11-25T13:31:01 < dongs> who the fuck in here would do shit in matlab before coding it
2014-11-25T13:31:33 < GargantuaSauce> probably more than you think
2014-11-25T13:31:57 < PaulFertser> Prototyping helps ensure it works with your current data, but doesn't guarantee you'll be fine through your whole input domain.
2014-11-25T13:32:46 < GargantuaSauce> i would say exactly the opposite is true, because you could check arbitrary ranges and combinations of input without the need for the rest of the system to play along and generate those values
2014-11-25T13:33:37 < PaulFertser> Right, but you check only what you check.
2014-11-25T13:34:06 < GargantuaSauce> well the alternative is adding potentially staggering amounts of overhead i think
2014-11-25T13:34:41 < GargantuaSauce> and any "protection" is going to produce bad results even if it prevents an overflow right?
2014-11-25T13:35:26 < PaulFertser> Right, it would be nice to be warned before runtime that something like that can happen.
2014-11-25T13:35:34 < GargantuaSauce> i guess
2014-11-25T13:35:48 < GargantuaSauce> rigorously providing that would involve solving the halting problem though would it not?
2014-11-25T13:36:05 < PaulFertser> E.g. you declare a bounded type and all your pure functions are formally verified to produce no overflows.
2014-11-25T13:36:06 < GargantuaSauce> and if you're relying on warnings that may not even occur then you're screwed
2014-11-25T13:36:26 < PaulFertser> Why halting problem, I'm talking only about pure functions here.
2014-11-25T13:36:36 < GargantuaSauce> ok yeah so you are talking formal verification
2014-11-25T13:36:45 < GargantuaSauce> which is exactly what a prototype would provide
2014-11-25T13:37:11 < GargantuaSauce> you aren't going to do that in c though without very stringent limitations on the coding style right?
2014-11-25T13:37:12 < PaulFertser> I'm not sure Octave is suitable for that kind of work.
2014-11-25T13:38:30 < PaulFertser> Probably for parts that need to be ultra-reliable something as restrictive as Atom would actually be nice?
2014-11-25T13:38:51 < GargantuaSauce> do it in haskell
2014-11-25T13:38:55 < GargantuaSauce> that'll get you on hacker news for sure
2014-11-25T13:39:24 < PaulFertser> Atom DSL is actually a Haskell-based DSL that can generate C code.
2014-11-25T13:39:53 < GargantuaSauce> well i am so glad reality is aligned with my sarcasm then
2014-11-25T13:39:57 < PaulFertser> Copilot is a project by Galois based on Atom. And I bet they wer eon hacker news.
2014-11-25T13:40:01 < dongs> ill just stick to writing shitty code
2014-11-25T13:40:16 < GargantuaSauce> actually that does sound pretty cool i think i'll check it out
2014-11-25T13:41:17 < PaulFertser> Also, there's Ajhc haskell implementation that for stm32s, but I'm not sure if that's worth it.
2014-11-25T13:41:50 < GargantuaSauce> yeah no i think generated code is probably the way to go
2014-11-25T13:42:27 < karlp> what's the motivation to genrate C instead of soemthing like clang intermediary or something?
2014-11-25T13:42:52 < dongs> so you can code in your favorite retard language ofhte week
2014-11-25T13:42:58 < dongs> like ruby or python or hakell or ??
2014-11-25T13:43:11 < GargantuaSauce> probably compiler independence?
2014-11-25T13:43:47 < karlp> GargantuaSauce: I guess, but seems like you then need to rely on C compilers far more, when you should have known more given you were generating from a model anyway
2014-11-25T13:43:58 < karlp> path of least resistance, rather than path of ideal solution I guess.
2014-11-25T13:45:58 < PaulFertser> http://compcert.inria.fr/doc/index.html there's also a formally verified C compiler.

2014-11-25T22:09:28 < Tectu_> awaq, I think it's time to leave :)
2014-11-25T22:09:48 < awaq> and so e.g. misc.h / misc.c is missing

2014-11-25T22:09:56 < awaq> and no libraries working

2014-11-25T22:10:11 < Tectu_> I can't
2014-11-25T22:10:21 < awaq> my question is only about the stm32f4-hal
2014-11-25T22:10:23 < gxti> awaq: google stm32f4-hal
2014-11-25T22:10:27 < jpa-> noo

2014-11-25T22:29:34 < Steffanx> hi awaq
2014-11-25T22:30:03 < reslit> i have one question for setting up the stm32f4 discovery clock at the HAL library
2014-11-25T22:30:27 < reslit> i din't found any defines for the PLL , only for the external osc. but nothing else
2014-11-25T22:30:37 < reslit> where can i find these settings?
2014-11-25T22:38:38 < Steffanx> reslit: is talking about stcubef4 HAL?
2014-11-25T22:38:55 < reslit> hm i think so
2014-11-25T22:39:04 < reslit> it is this what is generated by eclipse
2014-11-25T22:39:30 < Steffanx> then i don't know

2014-11-25T23:58:16 < KreAture> Steffanx it is not a freertos issue
2014-11-25T23:58:20 < KreAture> it is a setup issue
2014-11-25T23:58:31 < KreAture> I can share with you the chibi version too
2014-11-25T23:58:33 < KreAture> it crashes also
2014-11-25T23:58:43 < KreAture> it's a bit of a mess though
--- Day changed Wed Nov 26 2014
2014-11-26T00:00:16 < KreAture> must be my build environment or something hehe
2014-11-26T00:01:52 < Steffanx> Still emblocks?
2014-11-26T00:02:57 < KreAture> yes
2014-11-26T00:03:10 < KreAture> I will give chibi another go as I did not try the fix I did on freertos
2014-11-26T00:03:14 < KreAture> it may be a combo
2014-11-26T00:03:15 < KreAture> hehe
2014-11-26T00:05:09 < Steffanx> Can you share codez?

2014-11-26T00:08:15 < KreAture> I have problems getting the demos in there too as they all base on yagawhatthefuck
2014-11-26T00:09:31 < Steffanx> yagarto
2014-11-26T00:10:43 < KreAture> whatever
2014-11-26T00:11:05 < KreAture> I don't bother with anything starting with "yet another"
2014-11-26T00:13:19 < zyp> yagarto used to be a good option, but once gcc-arm-embedded came along, no other options makes sense anymore
2014-11-26T00:13:26 < Steffanx> Too bad this yet another toolchain is done, finished, finito, schluss
2014-11-26T00:14:23 < scummos> hmm, I'm trying to use DMA to transfer one block of RAM to a different block of RAM, but as soon as I enable the channel, the device "freezes"
2014-11-26T00:14:29 < scummos> on an LPC4333
2014-11-26T00:14:34 < KreAture> hehe
2014-11-26T00:15:01 < scummos> I wonder why that might be? the GPDMA doesn't even have clocks one can forget to turn on ;P
2014-11-26T00:16:27 < zyp> freezes in what sense?
2014-11-26T00:16:40 < KreAture> btw Steffanx I was meaning to ask before (last time you mentioned chibi) are none of the driver stuff included in any of the demos ?
2014-11-26T00:17:00 < KreAture> I've seen it go both ways before, some always include, others never include, and the worst ones include a mix
2014-11-26T00:17:22 < KreAture> I'd rather have a single common include but then again, you have no control over what you build later
2014-11-26T00:17:40 < KreAture> sourcecontrol on your project folder, and a different control on the libs would be disaster
2014-11-26T00:17:56 < zyp> I prefer git submodules
2014-11-26T00:18:21 < KreAture> too complicated
2014-11-26T00:18:29 < scummos> zyp: the enable command is followed by a loop which sends out a debug message via uart, and that transmission stops after a few characters were transmitted and then nothing happens any more
2014-11-26T00:18:32 < zyp> nah, it's easy
2014-11-26T00:19:00 < zyp> scummos, do you have a debugger hooked up?
2014-11-26T00:19:15 < scummos> no, I didn't yet buy one to be honest ;P
2014-11-26T00:19:23 < zyp> found your problem
2014-11-26T00:19:57 < zyp> get proper tools and stop guessing what your chip does
2014-11-26T00:20:06 < scummos> :D
2014-11-26T00:20:10 < scummos> ok, thanks for the advice
2014-11-26T00:20:41 < Steffanx> " are none of the driver stuff included in any of the demos " what driver stuff?
2014-11-26T00:22:47 < Steffanx> mr KreAture?
2014-11-26T00:23:12 < KreAture> Steffanx the demos I wanted to try out use usb and such
2014-11-26T00:23:24 < KreAture> but they just create the usb config structure
2014-11-26T00:23:37 < KreAture> and call a nonexistant function to enable it
2014-11-26T00:23:48 < zyp> nonexistent?
2014-11-26T00:23:55 < zyp> isn't the usb stack part of the hal?
2014-11-26T00:23:59 < KreAture> because it's part of the platform drivers from st I assume
2014-11-26T00:24:07 < KreAture> no hal supplied in the demos
2014-11-26T00:24:21 < KreAture> but the demos are specific for a cpu on that discovery board
2014-11-26T00:24:24 < KreAture> really odd
2014-11-26T00:24:24 < zyp> chibios doesn't use platform drivers, it has it's own hal
2014-11-26T00:25:11 < KreAture> then that should be somewhere then
2014-11-26T00:25:22 < KreAture> the readmes for the demos do not mention it
2014-11-26T00:25:31 < Steffanx> its in the HAL of chibios :)
2014-11-26T00:25:52 < KreAture> the demos do not contain chibios then
2014-11-26T00:25:58 < KreAture> only the files to use chibios
2014-11-26T00:26:03 < Steffanx> not sure what demo you are refering too
2014-11-26T00:26:13 < Steffanx> -o
2014-11-26T00:26:21 < KreAture> I looked at all of em
2014-11-26T00:26:25 < KreAture> yesterday and today infact
2014-11-26T00:26:32 < zyp> all of what?
2014-11-26T00:26:37 < zyp> please provide url
2014-11-26T00:26:42 < KreAture> ARMCM4-STM32F407-LWIP-FATFS-USB
2014-11-26T00:26:44 < KreAture> this one
2014-11-26T00:26:49 < KreAture> distributed with chibios
2014-11-26T00:26:53 < KreAture> in the demos folder
2014-11-26T00:27:04 < Steffanx> https://github.com/ChibiOS/ChibiOS-RT/blob/master/demos/STM32/RT-STM32F407-DISCOVERY-MEMS/main.c that one does cdc-usb ..
2014-11-26T00:27:35 < KreAture> that one too
2014-11-26T00:28:06 < KreAture> I notice they include a "hal.h" but that means I gotta merge in the os
2014-11-26T00:28:23 < KreAture> as I said, I would rather not play around with complex setups using multiple sources etc
2014-11-26T00:28:26 < zyp> are you not building with the included makefile?
2014-11-26T00:28:46 < KreAture> zyp I hate makefiles so I rather the ide handle it
2014-11-26T00:28:59 < zyp> so that's what you're doing wrong
2014-11-26T00:29:33 < KreAture> My point is, the makefile is using stuff from outside my project folder
2014-11-26T00:29:43 < KreAture> I utterly detest that as it has no fucking idea where I copied the demo to
2014-11-26T00:30:01 < zyp> you're obviously not supposed to copy out the demo
2014-11-26T00:30:05 < KreAture> The whole point of the demo is to have a simple start to modify
2014-11-26T00:30:27 < zyp> also, that's why the example makefile has a CHIBIOS variable for you to set
2014-11-26T00:30:42 < KreAture> and importing it all from outside like that makes it fiddly for anyone but the git ninjas to sourcecontrol
2014-11-26T00:31:06 < KreAture> zyp the variable makes it readable and manageable it does not help make it good
2014-11-26T00:31:33 < zyp> sure, I hate makefiles myself
2014-11-26T00:31:41 < KreAture> In a buisiness setting time is money and fiddling around with the sourcecontrol is not what I want to do
2014-11-26T00:32:08 < zyp> but your way is the wrong way to handle it
2014-11-26T00:32:17 < KreAture> no
2014-11-26T00:32:28 < KreAture> I just have to make sure to do it right
2014-11-26T00:32:42 < KreAture> The reason I asked was I asked if there was any "complete" examples
2014-11-26T00:32:46 < KreAture> standalone
2014-11-26T00:32:47 < zyp> it's still dumb even if you get it to work
2014-11-26T00:32:47 < KreAture> clean
2014-11-26T00:32:54 < zyp> heh
2014-11-26T00:32:56 < KreAture> what is ?
2014-11-26T00:33:01 < zyp> sounds like a maintenance hell
2014-11-26T00:33:07 < KreAture> getting a clean standalone copy of the tree needed for a project?
2014-11-26T00:33:31 < KreAture> The point is, all the open source monkeys love pulling in shit from anyone any time there is a update
2014-11-26T00:33:36 < KreAture> I cannot do that, I'd be fired
2014-11-26T00:34:17 < KreAture> once something is up and running, any change to it has to have a damn good reason, you don't update unless there is a serious bug.  New features are no reason
2014-11-26T00:34:27 < KreAture> embedded systems are not to be developed as pets that grow
2014-11-26T00:34:28 < KreAture> lol
2014-11-26T00:34:35 < zyp> how is that related to keeping the source maintainable?
2014-11-26T00:34:37 < KreAture> you can play on the linux box for that

2014-11-26T00:35:09 < KreAture> git has no issues merging in diffs
2014-11-26T00:35:26 < KreAture> as long as they are diffs from a given ref
2014-11-26T00:36:21 < zyp> ok, so you're committing yourself to only use a single version of a dependency throughout a project, fair enough
2014-11-26T00:36:35 < KreAture> yes
2014-11-26T00:36:51 < KreAture> you can change it, but you do that so it is reflected in the changelog
2014-11-26T00:37:16 < KreAture> if I pull up a 1 year old tag and try to check it out it has to make the same binary as before
2014-11-26T00:37:21 < zyp> yes, agreed

2014-11-26T00:37:30 < KreAture> if I want to use a later compiler I have to specify though
2014-11-26T00:37:35 < zyp> that's why I argue for submodules
2014-11-26T00:37:36 < KreAture> as they often change optimizing
2014-11-26T00:37:50 < Steffanx> So you also include the toolchain in all of your projects?
2014-11-26T00:38:00 < KreAture> I won't have issues with submodules but all the monkeys that eventually get involved have to use em right too

2014-11-26T00:38:48 < zyp> KreAture, ok, my mistake is assuming that everybody working on a project has common sense
2014-11-26T00:38:56 < KreAture> on medical stuff you have to be able to reproduce it a year later no hesitation

2014-11-26T00:39:10 < KreAture> hehe zyp I was just confused over how it was set up
2014-11-26T00:39:20 < KreAture> I thought the demos were standalone like the other os'es
2014-11-26T00:39:24 < KreAture> no biggie
2014-11-26T00:39:31 < KreAture> I see now how they are organized
2014-11-26T00:39:42 < KreAture> It just threw me into a hissyfit LOL
2014-11-26T00:39:50 < zyp> I don't like the layout
2014-11-26T00:40:32 < KreAture> If they are tidbits like this I'd rather them be organized by supplier and then by chip class
2014-11-26T00:41:30 < KreAture> anyway, on a few build systems I'd even have to do lots of tricks to get data at ../.. to work since the project would be on a virtual disk on root
2014-11-26T00:41:31 < KreAture> hehe
2014-11-26T00:41:36 < KreAture> there is no ..

2014-11-26T00:42:00  * KreAture imagines homer backing away slowly
2014-11-26T00:42:12 < Steffanx> not only homer
2014-11-26T00:43:36 < zyp> well, consider this, once checked out, submodules are equivalent to having deps in a subdirectory, the only difference is that you only store a remote reference instead of the whole contents of the dependency in your main project repo
2014-11-26T00:43:51 < zyp> so I imagine we have similar preferences in directory layout
2014-11-26T00:44:07 < zyp> wrt. project organization
2014-11-26T00:45:56 < zyp> I strongly disagree with letting the IDE handle anything though
2014-11-26T00:46:20 < zyp> you should be able to build a project without an IDE
2014-11-26T00:46:55 < zyp> and you should be able to build it without wasting a ton of time configuring the IDE
2014-11-26T00:47:27 < Steffanx> i remember Tectu being totally happy with em::blocks. He even made a chibios template for it.
2014-11-26T00:48:58 < KreAture> zyp well, the problem with most of the os supplie dmake stuff is they are never the same for a week
2014-11-26T00:49:11 < KreAture> They are constantly being changed and fiddled with
2014-11-26T00:49:33 < KreAture> you can ofcource just install a toolchain in a seperate folder and leave it
2014-11-26T00:49:46 < zyp> os supplied?
2014-11-26T00:49:59 < KreAture> cross compiling in linux
2014-11-26T00:50:00 < KreAture> hehe
2014-11-26T00:50:04 < zyp> which os? build host
2014-11-26T00:50:14 < KreAture> .
2014-11-26T00:50:35 < zyp> how is that relevant?
2014-11-26T00:50:49 < zyp> I mean, you're not using any build rules from the build host
2014-11-26T00:51:22 < KreAture> tell that to Joerg Schilling
2014-11-26T00:51:23 < KreAture> lol
2014-11-26T00:51:40 < KreAture> I remember a project we did involving his cdrtools stuff
2014-11-26T00:51:44 < KreAture> he made his own make
2014-11-26T00:51:53 < KreAture> nothing would build without using his tools
2014-11-26T00:51:54 < KreAture> hehe
2014-11-26T00:53:10 < zyp> I had a coworker using bsd make in a framework project once
2014-11-26T00:54:02 < zyp> so suddenly everyone have to install bsd make to build stuff building upon that
2014-11-26T00:55:11 < zyp> which is fair enough, if it weren't for the fact that none of the common distributions don't carry working copies of that
2014-11-26T00:55:18 < Steffanx> And you were not like: "STFU redo it using a proper make" ?
2014-11-26T00:55:45 < gnomad> Joerg Schilling definitely takes "not invented here" to the extreme.
2014-11-26T00:56:00 < zyp> so getting a proper build environment up and going was a pain
2014-11-26T00:56:27 < zyp> Steffanx, by the time I got involved with it, the damage was already done
2014-11-26T00:57:15 < KreAture> gnomad yes he does
2014-11-26T00:57:26 < KreAture> gnomad it was hillarious and frustrating at the same time
2014-11-26T00:57:44 < KreAture> My favourite was how linux ppl love to reuse code instead of making small tidbits they need
2014-11-26T00:58:18 < KreAture> It goes so far as to include 50 MB large libs to use a 3 line long function just to avoid duplicating it, only to have someone "fix it" and break your code half a year later
2014-11-26T00:58:23 < KreAture> gotta love that
2014-11-26T00:58:32 < Steffanx> Come on.. that happens everywhere
2014-11-26T00:58:40 < KreAture> Now it helps as you ref the specific version though, meaning you are in dll hell in linux
2014-11-26T00:58:40 < KreAture> hehe
2014-11-26T00:58:47 < Steffanx> especially in the world of web dev.
2014-11-26T00:58:50 < KreAture> 100 copies of the same liv
2014-11-26T00:58:52 < KreAture> lib
2014-11-26T00:58:55 < KreAture> hehe yes
2014-11-26T01:02:10 < englishman> Dongs http://hackaday.com/2014/11/23/down-the-rabbit-hole-of-stm32-clock-options/ first comment is someone that bought some crappy devboard and has no idea what to do with it lol
2014-11-26T01:03:28 < englishman> STM32F4 Discovery board + MicroPython = WIN
2014-11-26T01:04:12 < Steffanx> stop stop. We'll just pretend you didnt say that englishman
2014-11-26T01:04:22 < Steffanx> don't you know mr D. HATES python?
2014-11-26T01:06:00 < KreAture> lol
2014-11-26T01:10:31 < KreAture> zyp Steffanx was right on the template for emblocks
2014-11-26T01:10:35 < KreAture> I think that is the easiest weay
2014-11-26T01:10:42 < KreAture> it's a ready made clean setup for emblockas
2014-11-26T01:10:49 < KreAture> if I can't make that work I need my head examined
2014-11-26T01:10:51 < KreAture> lol
2014-11-26T01:11:39 < KreAture> It is also organizes the way "I like it"
2014-11-26T01:11:41 < KreAture> hehe
2014-11-26T01:11:51 < KreAture> and it is very easy to replace chibios in there with a new release
2014-11-26T01:11:52 < Steffanx> Thank mr Tectu
2014-11-26T01:12:14 < KreAture> hell, if I get the ball rolling and can start developing what I want to waste my time on I'll even buy him a beer
2014-11-26T01:12:52 < Steffanx> He prefers a sauna visit
2014-11-26T01:13:02 < KreAture> finish ?
2014-11-26T01:13:12  * KreAture goes to visit and brings the Tarrva shots
2014-11-26T01:13:31 < KreAture> hehe it builds
2014-11-26T01:13:52 < KreAture> Problem with emblocks and external makefiles it is is best at automatically managing em
2014-11-26T01:14:00 < KreAture> and throws a silent hissyfit if you don't let it
2014-11-26T01:14:30 < KreAture> what he has done is nicely assemble a project that allows all the deps to be included in such a way that emblocks makes the makefile correctly
2014-11-26T01:14:41 < KreAture> I am very excited to look at the build options though
2014-11-26T01:15:17 < Steffanx> it's very similar to yours except for some fpu stuff and startfiles stuff (iirc)
2014-11-26T01:15:32 < KreAture> see what I did wrong as this works
2014-11-26T01:15:59 < KreAture> I'll see if I can compare with the usb stuff and add it
2014-11-26T01:16:08 < KreAture> see if chibi is more friendly than freertos
2014-11-26T01:16:09 < KreAture> hehe

2014-11-26T17:06:51 < Getty> dongs: i have literally "no idea" what i have todo, and cant find that nice infos about it
2014-11-26T17:07:06 < Getty> dongs: it feels a bit like all documents expect you to know what todo 8-)
2014-11-26T17:07:19 < dongs> what is there "todo"?
2014-11-26T17:07:40 < dongs> you have a signal and a driver that turns it into A/B or A/B and a receiver that turns it into signal
2014-11-26T17:08:08 < Getty> so you say, when i attach a terminal to the serial, write something in and should just come out of the other side?
2014-11-26T17:08:38 < Getty> (cause right now i get just garbage, and i think its cause i should do something SPECIFIC over the serial when i want to send "any data")
2014-11-26T17:09:48 < Claude> Getty, don't forget about the TXEN and RXEN signals on RS485 transceivers :) e.g. one TXEN left enabled blocks the whole bus
2014-11-26T17:10:12 < dongs> also don't forget about drivers that are enable high or low
2014-11-26T17:10:36 < Getty> ok so there is more, ok! :)
2014-11-26T17:11:21 < Claude> yeah half duplex with the need to switch (at least) the TXEN pin when sending and receiving
2014-11-26T17:11:31 < Getty> its full duplex
2014-11-26T17:11:46 < Claude> oh 4 wire RS485 ?

2014-11-26T17:12:55 < Getty> i dont know ;) i just know the chip and saw that this is for sure full duplex (and thats what my dad told me)
2014-11-26T17:12:59 < Getty> here is what i got: http://i.imgur.com/5MHOEOs.jpg

2014-11-26T17:13:50 < Claude> Getty, doing multidrop or just point to point ?
2014-11-26T17:15:11 < Getty> Claude: for now its just that what i got, 2 points
2014-11-26T17:15:23 < Claude> ah okay nm , MAX3409 doesn't have TXEN and RXEN ;) so yeah then like you wrote : serial console is fine
2014-11-26T17:16:04 < Getty> mh but i just get garbage, but its precise the same garbage always ;)
2014-11-26T17:16:12 < Getty> like test gets to MFy
2014-11-26T17:16:12 < Laurenceb> dongs: nice
2014-11-26T17:16:40 < Claude> A/B Z/Y wired correctly ?

2014-11-26T17:17:16 < Claude> btw B and Y are positive and A and Z are the negative line
2014-11-26T17:17:27 < Getty> Claude: yeah well, my dad normally doesnt make mistake on that low amount of wires ;) but it COULD be that he does something wrong
2014-11-26T17:17:42 < Claude> Getty, :)
2014-11-26T17:18:04 < Getty> Claude: does it smell like something is just "other around"? i thought that might more end up in "nothing at all"
2014-11-26T17:18:46 < Claude> no the bits get inverted :)
2014-11-26T17:19:09 < Getty> Claude: what would be the way to test this? i mean, can i test if "test" converted gets to "MFy"?
2014-11-26T17:19:17 < Getty> s/converted/inverted/
2014-11-26T17:20:01 < dongs> bed
2014-11-26T17:21:40 < Getty> no wait... its not really related... its MFy or yyyyy what i get
2014-11-26T17:21:53 < Getty> no matter what i give in, let me test more
2014-11-26T17:22:20 < Getty> ah no no it is related, yeah... 6 gets to 2, 7 gets to d 8-)
2014-11-26T17:23:50 < Claude> Getty, i'm usually send the char "U" which turns into a "5" when it is inverted
2014-11-26T17:24:08 < Getty> LOL yeah well... U gets to.... <drumroll>
2014-11-26T17:24:11 < Getty> U
2014-11-26T17:24:15 < Claude> oh
2014-11-26T17:24:20 < Getty> yeah
2014-11-26T17:24:37 < Getty> yeah well, i can make U-protocol, a protocol based on U but i dont think thats wise
2014-11-26T17:24:38 < Getty> hahhaha
2014-11-26T17:25:24 < Claude> hmm try adding a termination resistor then (between A and B , and Z and Y as well) 120ohms
2014-11-26T17:25:56 < Claude> or anything around 120ohms will do it .. 100 or 200 doesn't matter for testing
2014-11-26T17:26:23 < Getty> damn it, my dad didnt put the layout on the share, else i could show you that, i will tell him todo so, then i can show you this

2014-11-26T17:29:40 < zyp> that would be RS422

2014-11-26T17:31:36 < dongs> with watermarks
2014-11-26T17:31:42 < Claude> zyp, ah right yeah
2014-11-26T17:31:45 < dongs> zyp: you probly wanna finalize parts list before weekend so it can get ordered
2014-11-26T17:31:57 < dongs> and stuff.
2014-11-26T17:32:04 < zyp> hmm
2014-11-26T17:32:12 < dongs> also if I recall F303 had some leadtime last 2 times
2014-11-26T17:32:26 < zyp> parts list for the boards itself would be the same as last time
2014-11-26T17:32:44 < dongs> what was unique on there so i can recall it
2014-11-26T17:32:48 < dongs> F303C8?
2014-11-26T17:32:49 < dongs> R7?
2014-11-26T17:32:51 < dongs> er R8?
2014-11-26T17:32:52 < dongs> i forget
2014-11-26T17:33:06 < dongs> but you also said you needed some jst-xh etc shit?
2014-11-26T17:33:15 < dongs> those can done separately sinec they're not going to pcba anyway.
2014-11-26T17:33:25 < zyp> yeah, that's what I was just thinking
2014-11-26T17:33:43 < dongs> http://bcas.tv/paste/results/sFGr8j51.html
2014-11-26T17:33:44 < dongs> is that it?
2014-11-26T17:33:46 < zyp> and then I need some L0s for the other shit,
2014-11-26T17:34:01 < zyp> but I guess those can be done separately too
2014-11-26T17:34:09 < zyp> yes, that looks right
2014-11-26T17:34:30 < dongs> Kk. i'll reorder that one tomrow them
2014-11-26T17:34:32 < dongs> then
2014-11-26T17:34:38 < zyp> great
2014-11-26T17:35:07 < zyp> I'll do the digikey for the XH shit going on the board tonight or tomorrow then
2014-11-26T17:35:09 < dongs> 130, fr4 is 112 and there's 7 panels remaining = 14 boards
2014-11-26T17:35:26 < zyp> hmm?
2014-11-26T17:35:32 < dongs> or do you need 100 exactly
2014-11-26T17:35:38 < dongs> theres 7 panels left from last order
2014-11-26T17:35:40 < dongs> blank ones
2014-11-26T17:35:40 < zyp> no, more is better
2014-11-26T17:35:50 < dongs> so it should be <= 130
2014-11-26T17:35:56 < zyp> hmm, okay
2014-11-26T17:36:02 < dongs> 126 if new fr4 is exactly 112
2014-11-26T17:36:06 < dongs> but usually theres a couple extra.
2014-11-26T17:36:16 < zyp> I'll order for 130 then
2014-11-26T17:36:53 < dongs> oh wait
2014-11-26T17:37:02 < dongs> new boards changed dip stuff isnt it
2014-11-26T17:37:03 < Laurenceb> punctuation sex: putting the semi in the colon
2014-11-26T17:37:12 < karlp> zyp: no, rs422 is specced as only poitn to point, rs485 is explicitly multipoint, regardless of whether it's wired for full duplex or half duplex

2014-11-26T17:37:26 < zyp> yes
2014-11-26T17:37:30 < zyp> there's no smt changes
2014-11-26T17:37:48 < zyp> the only change is the orientation of the QE1/QE2 sockets
2014-11-26T17:38:27 < karlp> ie, rs422 is rs485 with tx enable pins held permanently high.
2014-11-26T17:38:58 < zyp> karlp, how do you wire multipoint full duplex?
2014-11-26T17:39:38 < karlp> it's still only one talker, but rs485 with the tx enable pins let you have multiple talkers over time.
2014-11-26T17:39:53 < karlp> same wiring as full duplex rs422
2014-11-26T17:40:04 < karlp> only the wiring of the transceivers to your source/sink
2014-11-26T17:40:29 < Claude> i only seen RS422 (motor drives and inverters) as "token ring" style

2014-11-26T17:41:21 < zyp> «still only one talker» «full duplex» doesn't make sense
2014-11-26T17:41:57  * karlp shrugs
2014-11-26T17:42:20 < karlp> it's an academic difference, but 4 wire rs485 doesn't automatically make it rs422
2014-11-26T17:42:54 < zyp> I don't get it
2014-11-26T17:43:45 < karlp> rs422 is point to point, or multi drop only, not multi point.
2014-11-26T17:44:10 < zyp> by talker you mean like a master node? running master tx pair to multiple slave rx, and master rx pair to multiple slave tx?
2014-11-26T17:44:47 < dongs> omfg
2014-11-26T17:44:54 < dongs> i found a local shop for all my arduino needs https://www.switch-science.com/
2014-11-26T17:45:14 < emeb_mac> none IOW?
2014-11-26T17:46:03 < karlp> zyp: I mean, rs422 doesn't allow multiple driverfs
2014-11-26T17:46:06 < zyp> I know that RS422 is point to point, and that RS485 is multidrop with tx enable, what I don't get is why you'd want to have multiple pairs of RS485 in a way that doesn't make it equivalent to RS422
2014-11-26T17:46:16 < karlp> whether you wire a pair for rx and a pair for tx or not
2014-11-26T17:46:33 < Getty> Claude: "There is nothing wrong!" just gotta love my dad ;) i will come back to you when i get them, can be tomorrow
2014-11-26T17:46:34 < zyp> sure, I'm not arguing that
2014-11-26T17:46:45 < karlp> because in rs485, you _could_ have one driving one pair, and someoen else driving the other pair
2014-11-26T17:46:57 < qyx_> huh
2014-11-26T17:47:04 < karlp> but fuck it, just use two wires
2014-11-26T17:47:22 < zyp> karlp, yes, that's how RS422 works, which makes sense since you have as many drivers as pairs

2014-11-26T17:49:57 < karlp> zyp: yes, but if you're other devices are actually driving, it's no longer rs422, by definition of the standard,
2014-11-26T17:50:07 < karlp> even though these days the transceiver ics are the same
2014-11-26T17:51:14 < zyp> I just designed a board using RS485 the other day btw. :p
2014-11-26T17:51:18 < karlp> so for a four wire rs485, vs a two wire rs485, it potentially lets a slave device start replying while the master is still talking, if your chosen protocol allows that sort of thing
2014-11-26T17:51:29 < karlp> ie, if you're using modbus, you're just wasting wires :)
2014-11-26T17:51:51 < zyp> yeah, that's the thing I mean is pointless aboutit
2014-11-26T17:52:10 < zyp> it doesn't really make that much sense to design a protocol to allow that

2014-11-26T17:59:14 < karlp> the max3490 getty's using for instance is what you'd use :)
2014-11-26T17:59:23 < karlp> though I'd say that's normally used for rs422 installations instead
2014-11-26T17:59:33 < karlp> but it has the driver enable pins separate to be used for rs485.
2014-11-26T17:59:51 < karlp> then there's the fact that 2 wire actually means 3 wire anyway :)
2014-11-26T18:00:27 < zyp> 3490 doesn't have driver enable pins

2014-11-26T18:01:03 < zyp> 3491 does though, uses a larger package
2014-11-26T18:01:07 < karlp> guess it's a 422 driver then :)
2014-11-26T18:01:33 < karlp> oh, my wording was shitty with full duplex earlier, definitely, it should have been "bi directional half-duplex" or something equally shitty

2014-11-26T18:12:03 < Claude> at least it should be better than AVR gpios with zener diodes
2014-11-26T18:12:04 < gxti> wut
2014-11-26T18:12:13 < zyp> not similar enough, for usb you need to be able to assert SE0, not just J/K
2014-11-26T18:12:35 < Claude> ah right yeah forgot about the 'single ended' stuff in usb
2014-11-26T18:14:19 < karlp> is that a work thing zyp? or what does it actually do? (or is that particular one just going to be usb-cdc-acm to rs485?
2014-11-26T18:15:06 < zyp> no, private
2014-11-26T18:16:16 < zyp> I'm going to handle message framing in the firmware, and then just send each protocol packet as a full usb transfer
2014-11-26T18:16:30 < zyp> for some RS485 based protocol
2014-11-26T18:18:24 < zyp> what I'm wondering is whether I got A/B right
2014-11-26T18:18:26 < karlp> so what's the device with the usb a socket? is this arcade stuff again?
2014-11-26T18:18:31 < zyp> yep
2014-11-26T18:18:37 < karlp> a/b namign sucks arse
2014-11-26T18:18:55 < karlp> we have a document with all the third party elec/water meters we use and what names they use, and what pins to connect for each one.
2014-11-26T18:19:12 < zyp> protocol is JVS, used to communicate between boards in an arcade machine
2014-11-26T18:20:02 < zyp> a guy I know wanted to software emulate some stuff, so I'm making the hardware to facilitate that

2014-11-26T18:21:03 < Claude> <karlp> a/b namign sucks arse <--- full ack , did RS485 dataloggers for meters and inverters in my former job. A/B is usually just guesswork
2014-11-26T18:21:49 < zyp> there's a 50-50 chance I got it right on that board
2014-11-26T18:21:59 < zyp> I hope I won't have to rewire them
2014-11-26T18:22:55 < Claude> in the end i designed a polarity aware rs485 circuit for a datalogger :) little attiny85 searching for certain chars in the datastream (modbus for example) and the attiny flipped the bit on the fly

2014-11-26T18:24:42 < Claude> but there are rs485 trx from ti with a dedicated "flip" pin too

2014-11-26T18:27:29 < zyp> USARTx_CR2 has DATAINV, TXINV and RXINV bits
2014-11-26T18:27:31 < karlp> newer stm uart periphs have those options I believe
2014-11-26T18:27:35 < karlp> not f1 though
2014-11-26T18:27:49 < zyp> this is stm32l052, so it'd be the latest gen usart

2014-11-26T18:27:54 < karlp> yeah, lots of sexiness
2014-11-26T18:28:11 < zyp> looking forward to play around with it
2014-11-26T18:28:25 < Claude> iirc there was a small problem with the DC offset  , the 485 tx isn't biased at VCC/2 in the end
2014-11-26T18:28:44 < Claude> http://www.ti.com/product/sn65hvd888 <-- the ti one
2014-11-26T18:29:18 < zyp> eh, I'm not doing any biasing on my end
2014-11-26T18:29:37 < zyp> so I don't expect that to be a problem
2014-11-26T18:29:41 < Claude> yeah but internally in the trx there is some biasing
2014-11-26T18:31:37 < Claude> oh the TI one i linked too seems new , does the correction automatically

2014-11-26T19:00:04 < jorg> ok
2014-11-26T19:00:19 < zyp> does the stlink enumerate on usb?
2014-11-26T19:00:21 < jorg> it starts with some "errors" like after flashing a firmware all was ok
2014-11-26T19:00:35 < jorg> then it didnt start the software automatically
2014-11-26T19:00:39 < zyp> is the problem that the stlink doesn't show up, or is the problem that the stlink can't communicate with the target?
2014-11-26T19:00:40 < jorg> and now it cant connect
2014-11-26T19:00:49 < jorg> the stlink shows up
2014-11-26T19:01:08 < zyp> okay, so the problem is that the target is not responding over swd?

2014-11-26T19:20:19 < jorg> for what are the both on the bottom?
2014-11-26T19:20:23 < madist> there are jumpers on the bottom ?
2014-11-26T19:20:28 < jorg> yes
2014-11-26T19:20:35 < karlp> the IDD jumper?
2014-11-26T19:20:40 < Steffanx> ones you can solder, but those aren't important for you, yet.
2014-11-26T19:20:46 < karlp> not the solder jumps on the bottom side I would presume
2014-11-26T19:21:03 < madist> are they called jumpers or bridges ?
2014-11-26T19:21:06 < jorg> i mean jumpers i can set and remove
2014-11-26T19:21:12 < jorg> jumpers are there
2014-11-26T19:22:42 < jorg> hm now i can flash the board, but i have still a problem

2014-11-26T19:23:21 < jorg> but if i press reset or power board of and on the led dont blink, it only blinks after flashing
2014-11-26T19:25:24 < Steffanx> oh right there are jumpers on the botto(jp2 and jp3) m, but those "just" connect ground to ground.
2014-11-26T19:25:48 < jorg> hm ok but now it works
2014-11-26T19:25:58 < jorg> but how can i solve my 2cnd problem?
2014-11-26T19:28:01 < madist> JP2 and JP3 are for mechanical support.
2014-11-26T19:28:05 < madist> they're not jumpers.
2014-11-26T19:28:23 < Steffanx> They are jumpers.
2014-11-26T19:28:25 < jorg> ahh an jumper on the top i mean
2014-11-26T19:28:29 < jorg> not bottom ^^

2014-11-27T01:27:34 < KreAture> hey
2014-11-27T01:28:06 < KreAture> Steffanx I used Tectus template in emblocks and added usb
2014-11-27T01:28:25 < KreAture> it failed miserably and looking close at the asm I found it had only included the stub part of memcpy
2014-11-27T01:28:26 < KreAture> lol
2014-11-27T01:31:23 < KreAture> lol
2014-11-27T01:32:54 < brabo> i looked at emblocks yesterday
2014-11-27T01:33:14 < brabo> didn't really seem to like it

2014-11-27T01:40:04 < KreAture> it's now looking for driver for ChibiOS/RT virtual comport
2014-11-27T01:40:06 < KreAture> :)
2014-11-27T01:40:18 < KreAture> and hardfault
2014-11-27T01:40:20 < KreAture> hehe
2014-11-27T01:40:34 < brabo> KreAture: did you always use full ide's?
2014-11-27T01:41:08 < KreAture> not when developing on linux
2014-11-27T01:41:24 < KreAture> but normally I find a full ide saves lots of time
2014-11-27T01:41:34 < brabo> uhu
2014-11-27T01:41:36 < KreAture> this time though I am having issues with the build environment
2014-11-27T01:42:01 < brabo> up to now i'm just using sublime text and cli tools seperate
2014-11-27T01:42:35 < KreAture> I really like atmels studio which is based on visual studio.  It's lookup and such are quite good
2014-11-27T01:42:37 < KreAture> cross ref etc
2014-11-27T01:42:43 < brabo> have been looking around at ide's a bit, but it already annoys me that many vendors have their own ide,  mostly eclipse mods
2014-11-27T01:42:47 < KreAture> but it is too expensive for their arm chips
2014-11-27T01:42:58 < KreAture> yeah eclipse is too slow for me when I type
2014-11-27T01:43:03 < KreAture> it laggs
2014-11-27T01:43:03 < brabo> emblocks might be cool tho if i gave it a good try
2014-11-27T01:43:20 < brabo> ye i am not an eclipse fan :)
2014-11-27T01:43:22 < KreAture> so far I have used emtools for a few things and it has been great except for this stm32 affair
2014-11-27T01:43:32 < KreAture> I really like they support many vendors
2014-11-27T01:43:33 < brabo> ah
2014-11-27T01:43:40 < brabo> i am on stm32 atm
2014-11-27T01:43:44 < KreAture> and I like it was so little changes I needed to do on the keyboard shortcuts
2014-11-27T01:43:56 < KreAture> I am getting hardfaults on both freertos and chibios
2014-11-27T01:44:03 < KreAture> different faults though
2014-11-27T01:44:20 < KreAture> I think I like the coding style of freetros best though, calling convention and how it sets up threads
2014-11-27T01:45:19 < KreAture> I will never use a os that looks designed for an ape to say "I am hungry" with

2014-11-27T01:45:56 < KreAture> see, early metro ui!
2014-11-27T01:45:58 < KreAture> lol
2014-11-27T01:55:44 < KreAture> Hmm
2014-11-27T01:55:51 < KreAture> Seems like I am missing memset
2014-11-27T01:55:59 < KreAture> I was miossing memcpy so no surprise
2014-11-27T01:56:06 < KreAture> yey it works!
2014-11-27T01:56:08 < KreAture> :)
2014-11-27T01:56:20 < KreAture> why is there no memset or memcpy in my chibios copy ?
2014-11-27T01:56:30 < KreAture> it sais builtin but it only adds a stub
2014-11-27T01:56:35 < KreAture> the actual code is missing
2014-11-27T01:57:00 < KreAture> I made my own byte by byte one and it seems to do the trick
2014-11-27T01:59:13 < qyx_> wot
2014-11-27T01:59:20 < qyx_> isnt that thing in newlib?
2014-11-27T01:59:32 < KreAture> dunno
2014-11-27T01:59:59 < KreAture> but using barebones gcc from emblocks in a autogenerated makefile context with sources added in project seems to fubar that
2014-11-27T02:00:06 < KreAture> It does add the stub so it knows to add something
2014-11-27T02:00:22 < KreAture> but it doesn't seem to select between the c file or the .s file and I can't find either in the source tree!
2014-11-27T02:00:33 < qyx_> was it you with those weird alignment errors?
2014-11-27T02:00:39 < KreAture> yeah
2014-11-27T02:00:56 < KreAture> I tried chibios on a comment from Steffanx
2014-11-27T02:01:03 < qyx_> throw that emblocks thing out of window
2014-11-27T02:01:07 < KreAture> had some issues but I worked em out by using the debugger
2014-11-27T02:01:14 < KreAture> It now actually loads usb
2014-11-27T02:01:20 < KreAture> and is recognized correctly
2014-11-27T02:01:27 < qyx_> yep, it took only one week
2014-11-27T02:01:32 < KreAture> nope
2014-11-27T02:01:36 < KreAture> took 3 hours
2014-11-27T02:01:48  * brabo sips from his chimay bleu grande reserve
2014-11-27T02:01:49 < KreAture> cibi took less time than trying freertos
2014-11-27T02:01:54 < KreAture> also I only have evenings to work on it
2014-11-27T02:02:00 < brabo> damn.. they should have this everywhere
2014-11-27T02:03:46 < qyx_> so you spent 3 hours making chibios demo work?
2014-11-27T02:03:59 < qyx_> the usb cdc one or whatever is it?
2014-11-27T02:04:51 < KreAture> qyx_ no I spend that time making a template work with adding usb manually
2014-11-27T02:05:08 < KreAture> now I know what is needed and how it is organized in chibi
2014-11-27T02:05:17 < KreAture> seems quite straight forward
2014-11-27T02:05:34 < KreAture> only issue I have had has actually been the problems with missing memcpy and memset
2014-11-27T02:05:41 < KreAture> everything else worked first try
2014-11-27T02:10:52 < karlp> so you never actually wokrked out the hardfault, you just haven't seen it yet with this demo code?
2014-11-27T02:11:00 < karlp> can't wait til you move some code again ;)
2014-11-27T02:11:32 < KreAture> karlp The freertos hardfault was most likely something in the setup as I can now run all my code except the usb on that
2014-11-27T02:11:38 < KreAture> I can even add all the code
2014-11-27T02:11:48 < KreAture> it only fails when I init the usb which changes interrupt priority
2014-11-27T02:12:03 < KreAture> On chibios I am adding threads now to add complexity

2014-11-27T02:12:15 < KreAture> The usb is already working on that with a thread
2014-11-27T02:12:19 < karlp> so, it's still failing randomly an dyou have no idea why :)
2014-11-27T02:12:25 < KreAture> no it is not
2014-11-27T02:12:39 < KreAture> chibi has not failed after I added the missing "builtins"
2014-11-27T02:13:01 < KreAture> The other one fails and I have not yet bothered going through all the priority stuff to learn that
2014-11-27T02:13:07 < KreAture> I will do that later though
2014-11-27T02:18:03  * KreAture adds usb in a thread too to see it can run independantly
2014-11-27T02:20:47 < KreAture> Hmm, interesting
2014-11-27T02:21:40 < KreAture> in freertos you can set up a thread priority and it forces it to relinquish control.  chibios seems to require the thread to do so by sleeping or similar, especially main thread or it doesn't give any runtime to lower priority tasks
2014-11-27T02:21:45 < KreAture> I can live with that :)

2014-11-27T04:24:35 < dongs> no need for wizard shit
2014-11-27T04:24:49 < dongs> you only need it to make a template project, so just make one  manually, build it, then copypaste for all the other times you need t reuse it
2014-11-27T04:25:41 < dongs> why wouldnt they
2014-11-27T04:26:38 < dongs> seems to work ok
2014-11-27T04:26:46 < dongs> to get 3d controls i had to add new comctl manifest shit
2014-11-27T04:26:52 < dongs> or else they look xp'ish

2014-11-27T07:10:56 < upgrdman> englishman: it's annoying because many people aren't home when the mailman stops by. now i have to sign a slip and wait two days for redelivery
2014-11-27T07:11:25 < upgrdman> in the usa, it's almost unheard of to send merchandise as sig-req if the value is <$500
2014-11-27T07:11:38 < upgrdman> it's a waste of time and money
2014-11-27T07:12:19 < PaulFertser> R2COM: no, I do not write any papers. I was asking you because I assumed you're working in a field where an error in firmware costs a lot of money (and potentially human lives), so it'd be reasonable to take extra measures to prevent those.
2014-11-27T07:12:32 < PaulFertser> I think you've all heard about that killer x-ray machine.

2014-11-27T07:26:38 < PaulFertser> Bullet-proof HDL is also very interesting, it's just that I do not know what specifically to ask about it.

2014-11-27T12:30:40 < mervaka> seriously, fuck windows api
2014-11-27T12:31:08 < mervaka> abstract my vid/pid why don't you? cunting thing
2014-11-27T13:02:10 < dongs> Overall, the Nexus 6 display is quite poor relative to the displays on other smartphones like the Galaxy Note 4, iPhone 6, and HTC One (M7). It's also a definite regression from the display on the Nexus 5, which is concerning given the fact that the Nexus 6 is $300 more expensive.
2014-11-27T13:02:16 < dongs> haha
2014-11-27T13:02:25 < dongs> mervaka: what the fuck are you talking about

2014-11-27T13:05:28 < mervaka> except the windows API only passes device strings to the midi device
2014-11-27T13:05:35 < mervaka> not VID/PID
2014-11-27T13:05:46 < mervaka> but i guess it's not necessarily usb

2014-11-27T13:11:59 < dongs> shit, even S3 screen is probly better than dixus6
2014-11-27T13:15:21 < Angmar26> back in the days I had note 1, best smartphone I've ever had. big phat screen with ultra comfortable "hackers keyboard" and remote console without discomfort
2014-11-27T13:15:45 < dongs> all the pros now use itrash6
2014-11-27T13:16:42 < Angmar26> then I've got s4 it was big screen improvement but damn... I miss that 0.3" it's significaly more comfortable to use on screen keyboards on note1 than on s4

2014-11-27T15:47:37 < dongs> nobody wants to deal with lunix
2014-11-27T15:47:37 < dongs> right
2014-11-27T15:47:39 < ReadError> i would have killed myself too
2014-11-27T15:47:57 < dongs> <ReadStoner> I would have installed Mac OS XI server
2014-11-27T15:48:22 < Laurenceb_> but i dont know what im doing
2014-11-27T15:48:23 < ReadError> osx is awesome but rhel/centos is the only lunix server i would use
2014-11-27T15:48:36 < Laurenceb_> so thats why my inbox is full of angry emails
2014-11-27T15:48:40 < ReadError> ubuntu servers are such a joke
2014-11-27T15:48:51 < Laurenceb_> lol
2014-11-27T15:48:57 < Laurenceb_> ubuntu server is running fine
2014-11-27T15:49:03 < dongs> enjoy your systemd bro
2014-11-27T15:49:08 < Laurenceb_> i admin the ubuntu server
2014-11-27T15:49:19 < Laurenceb_> but it has to talk to legacy windoze land
2014-11-27T15:49:29 < Laurenceb_> which involves all the customers networks
2014-11-27T15:49:32 < Laurenceb_> and is a disaster
2014-11-27T15:51:28 < Laurenceb_> mainly as all the staff have left and there has been no maintainance for decades

2014-11-27T19:12:19 < Tekkkz> hi
2014-11-27T19:12:25 < Tectu_> yoooo
2014-11-27T19:12:37 < Tekkkz> I have a problem with compiling my program for the stm32f4 discovery
2014-11-27T19:13:08 < Tekkkz> i want to compile a program with usart library from uwe (http://mikrocontroller.bplaced.net/wordpress/?page_id=609)
2014-11-27T19:13:28 < Tekkkz> my project : http://www.mikrocontroller.net/attachment/238385/project.tar.gz
2014-11-27T19:13:37 < Tekkkz> and make error: http://pastebin.com/dzmGbYwh
2014-11-27T19:13:55 < Tectu_> wow, first linking to german articles, and then linking to direct downloads
2014-11-27T19:13:58 < Tectu_> nice work dude, nice fucking work
2014-11-27T19:14:03 < Tectu_> I'm deeply impressed
2014-11-27T19:14:08 < Tekkkz> what?
2014-11-27T19:14:15 < Tectu_> oh yay a paste, I take everything back
2014-11-27T19:14:42 < decimad2> well, did you link in the necessary parts of the stm periph lib?
2014-11-27T19:14:43 < Tekkkz> ^^
2014-11-27T19:14:59 < Tekkkz> i included them at my .h file
2014-11-27T19:15:03 < karlp> decimad2: "In 1970, a novel result in mathematical logic known as Matiyasevich's theorem settled the problem negatively: in general Diophantine problems are unsolvable."
2014-11-27T19:15:55 < decimad2> including the declarations is one thing, linking the definitions is the other
2014-11-27T19:16:02 < akaWolf> ahaha
2014-11-27T19:16:26 < Tekkkz> doesnt the makefile compile then? the link to there .h files is linked
2014-11-27T19:16:28 < akaWolf> you need not only include
2014-11-27T19:16:58 < decimad2> karlp: this is above my head. Can you translate for dummies?
2014-11-27T19:17:06 < akaWolf> but also say the linker
2014-11-27T19:17:08 < karlp> brute force for small ranges, or give up
2014-11-27T19:17:23 < decimad2> there's no smart search that works?
2014-11-27T19:17:43 < Tekkkz> for those who dont want to download full archive: my make file:
2014-11-27T19:17:49 < karlp> there's approaches: https://en.wikipedia.org/wiki/Hasse_principle
2014-11-27T19:18:08 < Tekkkz> pastebin.com/NUj1D7Qq
2014-11-27T19:18:27 < karlp> decimad2: or, you know, just don't bother trying.
2014-11-27T19:18:28 < akaWolf> Tekkkz: comon, man, just write -llib1 -llib2 ..
2014-11-27T19:18:36 < akaWolf> in the compile option
2014-11-27T19:18:37 < akaWolf> s
2014-11-27T19:18:40 < Tekkkz> ?
2014-11-27T19:18:43 < akaWolf> it's a directive for linker
2014-11-27T19:18:47 < Tekkkz> i dont use a ide
2014-11-27T19:19:01 < decimad2> karlp: Well the problem seemed "trivial", for some definition of trivial. It really puzzles me how this is not solvable O.O
2014-11-27T19:19:06 < akaWolf> I guest so...
2014-11-27T19:19:36 < karlp> decimad2: it's trivial indeed, for limited ranges, you just brute force it.
2014-11-27T19:19:47 < akaWolf> Tekkkz: just patch your Makefile
2014-11-27T19:19:48 < karlp> it's a https://en.wikipedia.org/wiki/Diophantine_equation
2014-11-27T19:20:21 < decimad2> karlp: that's what I settled on, you're explicitly meaning the pll-problem I stated above?
2014-11-27T19:20:29 < akaWolf> a club of the lovers of mathematica
2014-11-27T19:20:32 < akaWolf> ;)
2014-11-27T19:21:06 < karlp> decimad2: yeah, the pll auto select,
2014-11-27T19:21:23 < karlp> (there's a reason you haven't seen pll factor autoselect code alreay)
2014-11-27T19:21:26 < Tekkkz> how can i add the std periph librarys to my makefile build?
2014-11-27T19:21:40 < decimad2> karlp: thank you. That really astounds me... need to investigate this.

2014-11-27T19:23:12 < akaWolf> well
2014-11-27T19:23:16 < karlp> then add the .c files to be compiled

2014-11-27T19:23:21 < akaWolf> yeah
2014-11-27T19:23:25 < Tekkkz> ok wait a moment i test it
2014-11-27T19:23:35 < karlp> or, you know, file a bug with the person who gave you this code.
2014-11-27T19:23:50 < karlp> or decide whether code you randomly downloaded that didn't work out of the box is actualyl what you want to copy

2014-11-27T19:24:15 < Tekkkz> hm now it has another compiling error, should i pastebin it again?

2014-11-27T22:59:38 < zyp> yes, I got that much
2014-11-27T22:59:43 < zyp> but for which values?
2014-11-27T23:00:20 < karlp> the pll multiplier/divider options
2014-11-27T23:00:49 < zyp> what I'm leading up to is the question «why do you need to be able to find the closest approxmimation of say 123.45 MHz?»
2014-11-27T23:01:06 < karlp> because decimad likes that sort of optimization?
2014-11-27T23:01:22 < zyp> because if you don't, the problem is easy
2014-11-27T23:02:17 < zyp> you can generate any integer sysclk values if you just feed the PLL with 1 MHz, set the multiplication factor to 2*f and divide the output by 2
2014-11-27T23:02:33 < decimad2> hehe, this is hardly an optimization, I was just curious how to get the correct values no matter what, beside brute forcing.
2014-11-27T23:02:38 < zyp> so why do you need anything more than that?
2014-11-27T23:04:13 < zyp> or to put it a different way, if your application requires an arbitrary frequency with a greater precision than 1 MHz, you probably want to know the divider math anyway and not rely on some magic best approximation
2014-11-27T23:05:15 < zyp> so I don't understand the usefulness
2014-11-27T23:07:05 < decimad2> And what would I do to find the values in the case you stated?
2014-11-27T23:08:41 < decimad2> That's what I'm currently thinking about! All I could find where brute force loops and I was interested in a "smarter" approach.
2014-11-27T23:14:07 < zyp> decimad2, what do you mean?
2014-11-27T23:14:39 < decimad2> Well say I wanted some odd rational, I'd have to calculate it... And I was wondering just how.
2014-11-27T23:16:23 < zyp> and I'm saying you should answer the why before you begin thinking about the how
2014-11-27T23:17:20 < zyp> because otherwise you're wasting your time on something without any practical value
2014-11-27T23:17:44 < karlp> welcome to ##stm32 ;)
2014-11-27T23:19:39 < decimad2> Dude, I totally understand that I'm not spending my time for the progress of a real application here!
2014-11-27T23:20:26 < decimad2> It just so happend that I was curious how to find the closest constrained rational number to another quickly... ;)
2014-11-27T23:21:54 < zyp> prime factors, I'd guess
2014-11-27T23:24:50 < decimad2> Well the best I could come up with is brocot-stern binary search... which I must admit is practically not better than just brute force enumerating the denominators...

2014-11-28T00:44:16 < scummos> I use DMA to read from a GPIO port on an LPC4333 into SRAM. the transfers are triggered by a timer. I can't get that running faster than ~7M values per second. is that the actual limit of how fast GPIO-to-SRAM DMA is, or am I doing something wrong?

2014-11-28T00:51:53 < scummos> KreAture_: I thought it always shared the main clock?
2014-11-28T00:52:30 < KreAture_> I think you set up the clock
2014-11-28T00:52:33 < KreAture_> lemme check my settings
2014-11-28T00:53:18 < scummos> it says "base clock: BASE_M4_CLK"
2014-11-28T00:53:39 < scummos> bvernoux: hmm, I need to read 8 in parallel, do you think that'd be faster if it were SGPIOs?
2014-11-28T00:53:42 < bvernoux> scummos: you should run the code from SRAM too in a separate bank
2014-11-28T00:53:55 < bvernoux> scummos: NEVER execute code from SPIFI
2014-11-28T00:54:07 < bvernoux> it can be up to 20x slower than from SRAM
2014-11-28T00:54:16 < scummos> ok
2014-11-28T00:54:23 < scummos> but this is not really code running, it's the DMA, right?
2014-11-28T00:54:29 < bvernoux> scummos: SGPIO use CLK too and it is 100% HW
2014-11-28T00:54:38 < scummos> it could at most conflict with instruction fetch or so
2014-11-28T00:54:39 < bvernoux> check hackrf code about that
2014-11-28T00:54:46 < bvernoux> it does that at 20MHz
2014-11-28T00:55:02 < bvernoux> 8bits synchronized with CLK
2014-11-28T00:55:11 < bvernoux> but needs ASM of course
2014-11-28T00:55:41 < bvernoux> as M0 or M4 needs 8 cycles per access to SGPIO because it is located on a Bridge

2014-11-28T00:57:13 < bvernoux> anyway check hackrf fw code it is done with DMA now
2014-11-28T00:58:06 < scummos> unfortunately my peripherical device isn't connected to SGPIO ;P

2014-11-28T04:34:23 < dongs> i used toshiba websit inquery to rewquest info about 2 oddball mipi-dsi related chips
2014-11-28T04:34:32 < dongs> expected ignore and/or fuckoff
2014-11-28T04:34:37 < dongs> instead got email with datasheets for both
2014-11-28T04:45:29 < dongs> hm i got this 4L chinapcb back, i can see e-test marks on all pads
2014-11-28T04:45:35 < dongs> they should be moar careful
2014-11-28T04:45:54 < emeb> apparently not everyone is asleep at the wheel.
2014-11-28T04:47:25 < dongs> and.. this dumb chip wants 1.15V for core
2014-11-28T04:47:33 < dongs> .. while also needing 1.2V
2014-11-28T04:47:35 < dongs> come on
2014-11-28T04:48:17 < zyp> and of course they need to be more than 0.05V precise? :p
2014-11-28T04:49:03 < dongs> thats just fucking silly
2014-11-28T04:50:31 < dongs> yep, 1.1min, 1.15 typ, 1.2 max
2014-11-28T04:50:43 < dongs> the 1.2 one is 1.1 min, 1.2typ, 1.3 max
2014-11-28T04:51:09 < dongs> cockes
2014-11-28T04:57:41 < dongs> whats a standard HDMI plug these days
2014-11-28T04:57:45 < dongs> miniHDMI is dead?
2014-11-28T04:57:47 < dongs> is micro the new standard?
2014-11-28T04:58:22 < dongs> http://discountlowvoltage.blogspot.jp/2010/07/hdmi-mini-vs-hdmi-micro.html
2014-11-28T04:58:53 < dongs> Mini HDMI (Type C) is different because all positive signals of the differential pairs are swapped with their corresponding shield, the DDC/CEC Ground is assigned to pin 13 instead of pin 17, the CEC is assigned to pin 14 instead of pin 13, and the reserved pin is 17 instead of pin 14. The Micro (Type D) uses the same pin configuration as the standard HDMI (Type A).
2014-11-28T04:58:54 < qyx_> note to myself: always enable signed/unsigned comparison warnings
2014-11-28T04:58:59 < dongs> well thats no brainer
2014-11-28T04:59:01 < dongs> micro it is
2014-11-28T04:59:09 < dongs> this dumb swapped/oddball shit sounds like something I dont need
2014-11-28T05:00:04 < qyx_> wut
2014-11-28T05:00:23 < qyx_> why does a>b resolves as true if a is negative
2014-11-28T05:00:29 < qyx_> and a is signed, b is unsigned
2014-11-28T05:00:31 < qyx_> i mean, i know why
2014-11-28T05:00:32 < qyx_> but
2014-11-28T05:00:33 < qyx_> wtf
2014-11-28T05:00:40 < dongs> um duh bro
2014-11-28T05:00:42 < dongs> high bit
2014-11-28T05:00:46 < dongs> is set
2014-11-28T05:00:57 < qyx_> yep, but i would suppose that some implicit conversion magic happens
2014-11-28T05:01:06 < dongs> well, yes, unsigned turns to signed
2014-11-28T05:01:08 < dongs> then gets compared
2014-11-28T05:01:13 < qyx_> no
2014-11-28T05:01:29 < qyx_> if it would, then it compares as it should
2014-11-28T05:02:43 < dongs> hmm wait
2014-11-28T05:02:47 < dongs> micro can only handle to 1080piss
2014-11-28T05:02:53 < dongs> wtf is that shit
2014-11-28T05:02:54 < dongs> why no 4k
2014-11-28T05:03:07 < dongs> HDMI Micro Connector . A new, smaller connector for phones and other portable devices, supporting video resolutions up to 1080p. (more)

2014-11-28T05:06:38 < qyx_> with int replaced with long int, it works as expected
2014-11-28T05:06:43 < qyx_> fuk them
2014-11-28T05:06:51 < qyx_> c
2014-11-28T05:07:13 < zyp> what platform is this?
2014-11-28T05:07:24 < qyx_> Otherwise, if one operand is a long int and the other unsigned int, then if a long int can represent all the values of an unsigned int, the unsigned int shall be converted to a long int; otherwise both operands shall be converted to unsigned long int.
2014-11-28T05:07:26 < dongs> looks likel unix
2014-11-28T05:07:30 < qyx_> amd64
2014-11-28T05:08:07 < qyx_> i wonder who came up with this behaviour
2014-11-28T05:08:12 < dongs> http://images.apple.com/r/store/backsoon/1x-covers-animation-v3.gif
2014-11-28T05:08:15 < zyp> qyx_, well, to be fair, you're doing a signed to unsigned comparison
2014-11-28T05:08:18 < dongs> ffffffff
2014-11-28T05:08:20 < zyp> compilers will warn about that
2014-11-28T05:08:24 < dongs> the one fucking time
2014-11-28T05:08:27 < dongs> i go to apple store
2014-11-28T05:08:28 < dongs> its closed
2014-11-28T05:08:30 < dongs> rage
2014-11-28T05:08:41 < qyx_> zyp: yep, hence i said 03:58 < qyx_> note to myself: always enable signed/unsigned comparison warnings
2014-11-28T05:17:42 < qyx_> another note: strncpy doesn't terminate destination string if source overflows :S
2014-11-28T05:18:23 < qyx_> and another one: strnlen is not in C99
2014-11-28T05:18:41 < dongs> shit man, i thought everyone knew that
2014-11-28T05:18:56 < dongs> how would it terminate it if theres no more space left??
2014-11-28T05:19:27 < qyx_> depends on the point of view
2014-11-28T05:19:33 < qyx_> whats the point of having such function?
2014-11-28T05:19:51 < qyx_> you then have to replace the last character with '\0' to be sure
2014-11-28T05:20:27 < dongs> yes
2014-11-28T05:20:36 < dongs> thats why microsoft did those safe strings
2014-11-28T05:20:39 < dongs> cchstr* stuff
2014-11-28T05:20:52 < qyx_> maybe i just live in an ideal world when i just expect string functions to generate valid strings

2014-11-28T06:26:47 < zyp> that
2014-11-28T06:26:56 < akaWolf> dongs: for you -- yes
2014-11-28T06:27:04 < akaWolf> it's too subjective
2014-11-28T06:27:08 < dongs> i dunno man
2014-11-28T06:27:14 < dongs> like if y ou randomly walk around the street

2014-11-28T06:27:21 < dongs> to random people
2014-11-28T06:27:23 < akaWolf> :)
2014-11-28T06:27:24 < dongs> will they find it  funny?
2014-11-28T06:27:26 < dongs> probably notr.
2014-11-28T06:27:45 < akaWolf> I found that idea funny
2014-11-28T06:29:37 < dongs> youre a funny gui
2014-11-28T06:29:43 < akaWolf> also, I see only few good anime and only one funny (about Japanese anime)
2014-11-28T06:29:46 < zyp> to put it another way, I think that kind of humor is too dumb to be funny
2014-11-28T06:30:23 < dongs> akaWolf: what was good?
2014-11-28T06:30:39 < akaWolf> dongs: all about Ghibli, for example
2014-11-28T06:30:45 < dongs> i had no time to look into that shit for last few years, my impression was most of ~new shit was complte garbage
2014-11-28T06:30:57 < akaWolf> yeah, I agree
2014-11-28T06:31:00 < zyp> dongs, that's my impression too
2014-11-28T06:31:08 < dongs> ah, well, their stuff is oK but even latest stuff went downhill
2014-11-28T06:31:43 < akaWolf> I see all works by Ghibli
2014-11-28T06:31:55 < dongs> wind rises was like blah
2014-11-28T06:32:09 < dongs> not to mention 50% copypasted character designs
2014-11-28T06:32:39 < dongs> hah i downloaded somes hit in june and I dont remember watching it and now I dont even know what it is
2014-11-28T06:32:58 < zyp> hmm, I don't think I've watched any ghibli since arrietty
2014-11-28T06:33:04 < dongs> that one was ok
2014-11-28T06:33:07 < zyp> yeah

2014-11-28T06:33:56 < zyp> ok, but not as good as I expected it to be
2014-11-28T06:34:10 < dongs> i already forgot waht it was about so it couldnt have been that amaze
2014-11-28T06:34:28 < zyp> iirc some student/teacher relationship
2014-11-28T06:34:41 < akaWolf> more preferable for me: Totoro, Mononoke, Nausicaa
2014-11-28T06:35:11 < akaWolf> and soft romantic: Ocean Waves
2014-11-28T06:35:59 < dongs> hm i dont think ive seen that one
2014-11-28T06:36:04 < dongs> probably not until its out on bd

2014-11-28T06:39:56 < dongs> aptX Lossless supports high-definition audio up to 96 kHz sampling rates and sample resolutions up to 24 bits. The codec optionally permits a "hybrid" coding scheme for applications where average and/or peak compressed data rates must be capped at a constrained level. This involves the dynamic application of a form of "near lossless" coding . but only for those short sections of audio where completely lossless coding cannot respect the bandwidth constraints.
2014-11-28T06:40:02 < dongs> heh
2014-11-28T06:40:03 < dongs> even "losslesS" is still "almost lossless"

2014-11-28T08:51:46 < madist> C++ shows its benefits in very large projects where the abstraction helps understand/manage code that would otherwise be incomprehensible due to size.
2014-11-28T08:51:51 < madist> that's what Stroustrup says.
2014-11-28T08:52:05 < madist> on a uC you shouldn't usually have that situation.

2014-11-28T08:52:32 < madist> I said usually.
2014-11-28T08:52:40 < madist> that's not complex.
2014-11-28T08:53:10 < madist> not if it adds complexity.
2014-11-28T08:53:40 < madist> C++ is easier than C to port ?
2014-11-28T08:53:57 < madist> that doesn't make sense.
2014-11-28T08:54:42 < madist> and if its written in visual basic then its easier to port than convert to c.
2014-11-28T08:55:38 < PaulFertser> And if it's written in Forth, it's easier to write a Forth machine for the target, yay!
2014-11-28T08:55:50 < decimad2> Is there an stm description file that would also listen the fields inside the registers?
2014-11-28T08:55:53 < madist> I think the problem with C++ is that there are 2 types of people: the ones who want to go down to bare metal and they use C. and the ones who are scared of computers and they use Java/C#.
2014-11-28T08:56:07 < madist> C++ is somewhere inbetween those 2 extremes so it appeals to nobody.
2014-11-28T08:56:26 < madist> R2COM: why ?
2014-11-28T08:56:58 < decimad2> c++ problem really is that everybody understands it differently, since it's a vast toolset, and that 99% use plain C, so C++ guys need to help themselves, since vendors supply plain C
2014-11-28T08:57:07 < madist> even Stroustrup goes out of his way to emphasise that C++ is not higher overhead than C.
2014-11-28T08:57:09 < PaulFertser> R2COM: my own humble opinion regarding C++ is that it's currently a great system programming language, very suitable for microcontrollers provided one understand its template magic well, and doesn't use inheritance from non-abstract classes (which I consider bad for almost every usecase).
2014-11-28T08:58:22 < madist> it can't be.
2014-11-28T08:58:27 < PaulFertser> When properly applied, yes.
2014-11-28T08:58:30 < madist> its C plus some shit.
2014-11-28T08:58:43 < madist> PaulFertser: explain ? (if you have the time)
2014-11-28T08:59:54 < PaulFertser> madist: C programmers can't usually hand-tune plenty of things that can be done compile-time in C++, i.e. C++ allows you to generate specialized code compile-time, and then the compiler optimises it nicely. With C you either loose readability and maintainability doing the same manually for the specific case or settle on a less efficient but readable implementation.
2014-11-28T09:00:44 < decimad2> Or you're STM and you settle on an unreadable inefficient implementation

2014-11-28T09:01:06 < PaulFertser> I hope decimad2 and zyp can clarify my point better, I'm not that experienced in C++ actually.
2014-11-28T09:01:08 < madist> compiler optimization is something I don't understand. :/
2014-11-28T09:01:12 < madist> I should learn.
2014-11-28T09:01:52 < PaulFertser> I can't say I like how its template language accidentally turned into a Turing complete purely functional one. It provides great facilities but it's also very clumsy.

2014-11-28T09:02:29 < madist> i've seen crappy template code that produced 20 line syntax errors.
2014-11-28T09:02:44 < PaulFertser> Of course code written by your average "C++ programmer" (which uses C++ as if it is a weird Java dialect) is usually less efficient than nice C code.
2014-11-28T09:02:54 < PaulFertser> 20 line is nothing!
2014-11-28T09:03:18 < madist> I mean the name of the offending variable/class was 20 lines long.
2014-11-28T09:03:25 < PaulFertser> One of the hot topics in C++ is "concepts" which should hopefully help making template errors more understandable.
2014-11-28T09:03:41 < PaulFertser> Yeah, 20 lines is not much by C++ standards, unfortunately.
2014-11-28T09:04:46 < decimad2> I guess zyp is the better partner. Recently I'm focused on template magic and using it for low- to mid-level stuff which obviously doesn't pay off if its not a frequently used lib.
2014-11-28T09:05:54 < PaulFertser> decimad2: please feel free to correct me when I'm stating something obviously wrong :)
2014-11-28T09:06:08 < decimad2> I am offended my SOMEREGISTER = (SOMEREGISTER & ~mask) | (FOOMACRO & FOOMASK) | (BARMACRO(bla) & BARMASK); style of coding...
2014-11-28T09:07:03 < decimad2> but that usually lowlevel code that you can argue about: "Nobody sees that stuff on high level".
2014-11-28T09:08:41 < decimad2> I'm not so sure, if you're the only one who uses the groundwork that is bound to be created for it. Every vendor lib is C after all.
2014-11-28T09:10:14 < decimad2> Well if you're reimplementing the lib, then there's no reason not to use C++ on spots where it makes the code itself or the caller coder clearer, safer or faster.

2014-11-28T09:12:07 < madist> same reason why they hate windows. its fashionable and they're not intelligent enough to think independently.
2014-11-28T09:12:10 < decimad2> Well, it's attacked from multiple sides. There are the ones who ASM on 8-Bit AVRs, the ones who don't want to learn C++ etc.
2014-11-28T09:13:17 < decimad2> Then there are the ones that see C++ as Java...
2014-11-28T09:13:46 < decimad2> Some people don't get that you don't even need to go OOP with C++ and still benefit
2014-11-28T09:14:39 < decimad2> I mean, namespaces, templates, const stuff, references, type safety is good imho. Don't understand why you wouldn't want that in your toolset if it comes "for free".
2014-11-28T09:15:43 < decimad2> Not having to write typedef struct foo_t {} foo; or void foo( struct foo_t* bla ) {}...
2014-11-28T09:16:19 < decimad2> I don't know if you can portably define variables inside functions yet...
2014-11-28T09:16:28 < decimad2> I mean in the middle of them...
2014-11-28T09:19:13 < decimad2> R2COM: But bear with me... I come frome Desktop-C++, which obviously benefits "most" from C++, thus my cost to learn C++ for µC is only to learn what not to do or what to do differently, because problems differ.
2014-11-28T09:21:00 < decimad2> That's exaggerated I guess
2014-11-28T09:21:02 < PaulFertser> madist: I've spent too much time fighting windows-specific issues in my life. When it works, it works, but when it breaks, you have to go horrible ways trying to understand what and where broke, and often there's no way to fix, a silly workaround at best. So I do have very strong reasons to keep away from that insane family of os's.
2014-11-28T09:21:53 < decimad2> "This hadn't happened with linux (tm)"
2014-11-28T09:21:57 < madist> R2COM: the difference is that with other OSes you can find out what and why.
2014-11-28T09:22:05 < PaulFertser> Every does break. But with GNU/Linux I have means to understand and debug the breakage.
2014-11-28T09:22:32 < madist> however bad windows is in that respect, linux is nowhere near usable on the desktop.
2014-11-28T09:22:42 < PaulFertser> Depends on your usecase of course.
2014-11-28T09:22:52 < PaulFertser> E.g. I can hardly imagine using a desktop without tiling WMs.
2014-11-28T09:23:17 < PaulFertser> Also, I do not see how desktop users do not need proper repository for software management etc.
2014-11-28T09:23:42 < madist> glad to have made your day.
2014-11-28T09:24:09 < madist> PaulFertser: I don't think there is any OSS tool that doesn't work on Windows too ?
2014-11-28T09:24:12 < PaulFertser> R2COM: it's not unusual for me to find problems bothering me inside huge projects (such as the kernel) and fix them.
2014-11-28T09:24:22 < decimad2> It might happen that I need to set up some linux box for a ptp daemon, would anyone be willing to help in case? :)
2014-11-28T09:24:28 < PaulFertser> R2COM: I sometimes do that, yes.
2014-11-28T09:26:13 < PaulFertser> R2COM: indeed. I'm not a scientist, unfortunately, just an engineer. But when you're using windows you can hardly hire any professional to fix its bugs, it either works for you, or you suffer from some bug. With GNU/Linux you'd simply hired a professional to fix it for you.
2014-11-28T09:26:45 < PaulFertser> My experience was different.
2014-11-28T09:27:30 < PaulFertser> I haven't heard a single story how microsoft support really helped anybody with any semi-serious issue.
2014-11-28T09:29:36 < decimad2> What problems do you run into btw? Also just dipping into kernel code and fixing stuff quickly sounds liker super-programmer. I mean you can't even debug it without deep knowledge, I guess?
2014-11-28T09:31:37 < decimad2> Don't over-do like I am... ;)
2014-11-28T09:32:04 < decimad2> What can be solved at compile time with templates, I try to do.
2014-11-28T09:32:20 < decimad2> It's just personal fun... ;)
2014-11-28T09:32:42 < decimad2> you mean templates? yeah
2014-11-28T09:32:53 < PaulFertser> decimad2: e.g. https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=bcf64aa379fcadd074449cbf0c049da70071b06f was easy enough

2014-11-28T14:10:20 < chickensk> PB7 jumper is open (they write OFF in the manual)
2014-11-28T14:10:42 < chickensk> and it also can not flash internal MCU when swd wires are connected
2014-11-28T14:12:43 < karlp> chickensk: that's not an error, it's a warning, and can be ignored.

2014-11-28T15:07:32 < Laurenceb> but ive just had a case of a user getting a device into some weird state where it wont turn off

2014-11-28T15:08:18 < Laurenceb> any idea what state it could have been in?

2014-11-28T15:35:20 < Laurenceb> maybe the usb cable was intermittently making contact
2014-11-28T15:35:53 < Laurenceb> CONFIGURED -> SUSPEND automatically due to no packets for 3ms, but then it reattaches and gets itself into some weird state?
2014-11-28T15:36:38 < Laurenceb> annoyingly on early hardware versions i ran out of io pins, so the lipo charger has to be turned off the check v_usb
2014-11-28T15:37:14 < Laurenceb> so if i remove  && bDeviceState == SUSPENDED charger led is going to be flashing all the time

2014-11-28T15:47:25 < Tekkkz> i have a problem with my code for stm32f4 discovery
2014-11-28T15:48:10 < Tekkkz> the following code is only writen into ram and not flash, because it doesnt start this program after reset or repowering: http://pastebin.com/Pj0igwTZ
2014-11-28T15:48:30 < Tekkkz> with other codes it works, why dont work this / or is only written to ram?
2014-11-28T15:48:41 < dongs> holy shit
2014-11-28T15:48:48 < Tekkkz> ?
2014-11-28T15:48:59 < dongs> that code
2014-11-28T15:49:00 < Laurenceb> http://pastie.org/9748559
2014-11-28T15:49:06 < Laurenceb> i fail at logic
2014-11-28T15:49:30 < Tekkkz> whats with my code?
2014-11-28T15:49:37 < dongs> whats wrong wiht it?
2014-11-28T15:49:40 < dongs> well, where the fuck do i start
2014-11-28T15:49:40 < Laurenceb> and brackets
2014-11-28T15:50:01 < Tekkkz> ?
2014-11-28T15:50:21 < Laurenceb> Tekkz: why not just write machine code
2014-11-28T15:50:26 < Laurenceb> you are pretty close
2014-11-28T15:50:34 < dongs> yeah just start coding in thumb2 asm
2014-11-28T15:50:38 < dongs> why waste time wiht this C shit
2014-11-28T15:50:39 < Laurenceb> no

2014-11-28T15:50:47 < Laurenceb> on paper
2014-11-28T15:50:48 < dongs> oh yeah, or that

2014-11-28T15:52:11 < madist> wat shit pastebin is that. can't read a line without moving the scrollbar.
2014-11-28T15:52:20 < dongs> thats his shit code
2014-11-28T15:52:24 < dongs> cuz he doesnt know how to indent
2014-11-28T15:52:28 < Laurenceb> lol
2014-11-28T15:52:36 < Tekkkz> berk no adresses at this code berk
2014-11-28T15:52:57 < Laurenceb> hmm i think this should fix the problem
2014-11-28T15:53:24 < Laurenceb> usb plugs are annoying, all kind of crazy shit happens during poor plug/unplug action by the user
2014-11-28T15:55:27 < Laurenceb> pity its impossible to test
2014-11-28T15:55:42 < Laurenceb> i need to make a usb plug clusterfucker
2014-11-28T15:56:18 < madist> plug/unplug transients should be a well studied thing surely ?
2014-11-28T15:56:26 < Tekkkz> and btw im using adresses and not the c api so really because i hate it to setup an led i need a complete GPIO_InitTypeDef
2014-11-28T15:56:29 < madist> there's no wait for connection to settle or something like that ?
2014-11-28T15:57:23 < madist> header files are for faggots. real men memorise addresses of all peripheral registers.
2014-11-28T15:59:22 < Tekkkz> ??
2014-11-28T15:59:24 < Tekkkz> what do you mean?
2014-11-28T16:00:12 < dongs> i know know writing 0xdeadbeef to 0x7a691818 sets the FAGGOT flag
2014-11-28T16:00:41 < dongs> Tekkkz: why do you bother including stm32f4xx.h if you aint gonna use it
2014-11-28T16:01:27 < madist> if you don't include stm32f4xx.h then double click on the address won't take you to the definition. and you won't know the meaning of the address.
2014-11-28T16:01:40 < Tekkkz> hm ok will use it, but how do i use it with blah   GPIO_InitTypeDef for some port operations?
2014-11-28T16:01:50 < Tekkkz> I look up the adresses at the data sheet -.-
2014-11-28T16:01:56 < dongs> ...
2014-11-28T16:02:13 < Tekkkz> and im programming in a text editor, there dont work a click on it
2014-11-28T16:02:27 < dongs> are you using lunix?
2014-11-28T16:02:51 < dongs> open that stm32f4xx.h and read through it
2014-11-28T16:03:08 < dongs> Look for stuff like ***_TypeDef structs
2014-11-28T16:03:10 < dongs> for GPIO, etc
2014-11-28T16:03:13 < dongs> those are the registers
2014-11-28T16:03:26 < dongs> so you do GPIOA->ODR = foo;
2014-11-28T16:03:33 < dongs> at least shit is more readable
2014-11-28T16:04:06 < Tekkkz> this works? GPIOA->ODR= foo?
2014-11-28T16:07:13 < dongs> yes
2014-11-28T16:07:15 < dongs> it is same as
2014-11-28T16:07:20 < dongs>  *((uint32_t volatile *)(0x40020C18))=(1<<12+i);
2014-11-28T16:07:21 < dongs> i guess
2014-11-28T16:07:39 < dongs> if tyou're trying to write to some pin
2014-11-28T16:08:48 < dongs> or BRR or BSRR or whatever youre trying to do
2014-11-28T16:09:01 < dongs> all the definitions are in that .h and i think(?) they match whats in datasheet
2014-11-28T16:09:42 < Tekkkz> ahh yes i see it
2014-11-28T16:09:45 < Tekkkz> thanks, its nice
2014-11-28T16:10:34 < dongs> and in Peripheral_declaration group there's all the peripherals mapped to those typedefs
2014-11-28T16:10:43 < dongs> #define GPIOA               ((GPIO_TypeDef *) GPIOA_BASE)

2014-11-28T17:28:10 < brabo> Tekkkz: i had same experience using st-flash.. connecting st-util and flashing with gdb works fine tho
2014-11-28T17:28:10 < madist> that's irrelevant
2014-11-28T17:28:16 < madist> the LED stops in some random state
2014-11-28T17:28:23 < madist> sometimes its on sometimes its off.
2014-11-28T17:28:53 < madist> actually, its on initially when I power up my discovery board. but after I program the chip it stays off.
2014-11-28T17:29:26 < madist> on/off = red/green.
2014-11-28T17:30:16 < Tekkkz> hm ok, how to programm with gdb?
2014-11-28T17:30:29 < brabo> Tekkkz: well, i just run st-util
2014-11-28T17:30:44 < brabo> normally that will connect to the board
2014-11-28T17:30:56 < brabo> then like: gdb main.elf
2014-11-28T17:31:04 < brabo> tar extended-remote :4242
2014-11-28T17:31:05 < brabo> load
2014-11-28T17:31:17 < brabo> then 'c' to run it
2014-11-28T17:31:31 < brabo> i should probably look into openocd..
2014-11-28T17:31:56 < Tekkkz> ok
2014-11-28T17:32:07 < Tekkkz> but why not st-flash? do it make errors?
2014-11-28T17:32:33 < brabo> idk.. i have tried it some times, didn't seem to work, gdb works just fine, so i use that hehe
2014-11-28T17:32:44 < Tekkkz> ok
2014-11-28T17:33:09 < brabo> nothing lost by trying it that way.. if you are lucky it Just Works TM ;)
2014-11-28T17:33:28 < Steffanx> or stop using those tools at all and go openocd :P
2014-11-28T17:33:51 < Tekkkz> hm ok but why dont work st-flash?
2014-11-28T17:34:11 < brabo> ye i should.. too pressed atm to occupy myself with that

2014-11-28T17:40:07 < Tekkkz> hm how do i upload with gdb??
2014-11-28T17:43:13 < brabo> qyx_: nice post about the c string functions
2014-11-28T17:43:58 < brabo> Tekkkz: well, as i said, running st-util will make it connect to the board, then running 'gdb main.elf' starts gdb with telling it we will use main.elf
2014-11-28T17:44:18 < brabo> then when it started, doing 'tar extended-remote :4242' will connect gdb to the running st-util
2014-11-28T17:44:35 < brabo> then 'load' will load the code to the board
2014-11-28T17:45:01 < brabo> at that point, just doing 'c' (short for continue) should execute your code
2014-11-28T17:45:21 < Tekkkz> and then how to leave gdb?
2014-11-28T17:45:25 < brabo> as Steffanx said tho, this can all be repaced by using openocd with a good configuration
2014-11-28T17:45:37 < brabo> Tekkkz: ctrl-c ctrl-d y
2014-11-28T17:45:45 < Tekkkz> kk
2014-11-28T17:45:49 < Tekkkz> i will try
2014-11-28T17:46:10 < brabo> atm i am using this method, but with .gdbinit file that runs a base set of commands
2014-11-28T17:46:23 < Tekkkz> can you post the file?
2014-11-28T17:46:24 < brabo> we both should look at openocd hehe
2014-11-28T17:46:36 < brabo> sure, it is not complex
2014-11-28T17:47:50 < Tekkkz> btw with your method
2014-11-28T17:47:57 < Tekkkz> the code is removed after reset too

2014-11-28T17:49:14 < brabo> removed after reset? hmmm

2014-11-28T17:59:19 < brabo> i suggest perhaps you ghet libopencm3 and get the f4 linker file
2014-11-28T17:59:37 < brabo> it cannot be more wrong than the f1 one hehe
2014-11-28T17:59:42 < Tekkkz> ahh ok, btw i found my mistake

2014-11-28T18:04:15 < qyx_> huh fileuploader
2014-11-28T18:04:37 < brabo> Tekkkz: good question.. i always use some shell with a webdir
2014-11-28T18:04:47 < Tekkkz> i have an idea
2014-11-28T18:04:51 < Tekkkz> i take my own server
2014-11-28T18:04:53 < Tekkkz> wait a moment
2014-11-28T18:05:23 < dongs> no cluei

2014-11-28T18:09:00 < Tekkkz> the "template" is the template im using, there all works, with st-flash too
2014-11-28T18:09:12 < Tekkkz> and at my modified version, the code isn written ino flash... why?
2014-11-28T18:09:18 < Tekkkz> what have i diferent?

2014-11-28T18:15:28 < Tekkkz> ?
2014-11-28T18:16:51 < brabo> Tekkkz: well
2014-11-28T18:16:55 < Tekkkz> ?
2014-11-28T18:16:59 < brabo> you are compiling to binary
2014-11-28T18:17:04 < brabo> the template to ihex
2014-11-28T18:17:08 < brabo> that is one thing i see
2014-11-28T18:17:14 < karlp> you're not including: template/lib/src/peripherals/stm32f4xx_syscfg.c ?
2014-11-28T18:17:23 < Tekkkz> is it important to include?
2014-11-28T18:17:25 < brabo> yes also those
2014-11-28T18:17:38 < karlp> maybe not, you're probably not using those functions?

2014-11-28T18:18:09 < Tekkkz> karlp what do you mean?
2014-11-28T18:18:15 < brabo> personally i just do not see why you are not using the same Makefile?
2014-11-28T18:19:07 < Tekkkz> i just removed the source files i dont need i think, you know?
2014-11-28T18:19:57 < brabo> well removing things that you think are not important always are worth a closer look if you remove em and things fail
2014-11-28T18:20:02 < trepidaciousMBR> Hm, the reference manual for the STM32F437 states that in AES GCM mode, the header must be a multiple of 128 bits, but that doesn't seem right since GCM is streaming. Maybe it's just a restriction of this implementation.
2014-11-28T18:20:34 < Tekkkz> i dont understand?
2014-11-28T18:21:39 < brabo> Tekkkz: if you remove something you think is nor important, and things fail, perhaps it was important after all? so, copy the template directory, add your main.c, only edit the Maefile enough to assure your c file gets compiled, and try it again
2014-11-28T18:22:02 < Tekkkz> ok i try, wait a moment
2014-11-28T18:29:24 < Tekkkz> hmpf my st link dont work

2014-11-29T00:39:59 < brabo> i guess it should go on, if that is the rigght port and pin, and i'm not sure about that MODER
2014-11-29T00:40:22 < brabo> i don't use the st periph lib
2014-11-29T00:43:02 < Tekkkz> ok
2014-11-29T00:43:10 < brabo> i found the style horrible, and a friend told me about libopencm3 and i have to say it is a nice library
2014-11-29T00:43:13 < Tekkkz> but it should blink (bec dely, but this dont work
2014-11-29T00:43:27 < brabo> you are not toggling it
2014-11-29T00:43:35 < brabo> so it would burn steady
2014-11-29T00:45:29 < Tekkkz> ahh yes right, my fault ^^
2014-11-29T00:45:41 < brabo> it happens
2014-11-29T00:45:59 < brabo> but have a look at libopencm3 and see if you like it too ;)
2014-11-29T00:46:47 < brabo> it's not hard to use, and it is active
2014-11-29T00:47:09 < Tekkkz> ok i will look tomorrow, i live in germany and there its now 23:47 so im going to sleep now, good night

2014-11-29T02:21:27 < brabo> that looks fucked..
2014-11-29T02:21:45 < dongs> its not, its just directly writing to peripheral memory
2014-11-29T02:21:56 < dongs> without using the gpio/rcc structs
2014-11-29T02:22:02 < dongs> from the header he did include.
2014-11-29T02:22:22 < dongs> first write is like RCC->APB1ENR = 0x08 etc
2014-11-29T02:22:29 < dongs> that kinda shit.
2014-11-29T02:22:39 < brabo> yea, but who would do that? seems to me it's only making things unnessecary hard
2014-11-29T02:26:38 < englishman> and hes including the stdlib stuff
2014-11-29T02:27:03 < englishman> i bet it takes longer to do the math and find the proper register address and values to put in it than rcc->blag
2014-11-29T02:27:26 < brabo> probably, and debug it as well

2014-11-29T04:25:30 < dongs> You may have noticed that Borut Ra.em, one of our developers, hasn't posted to the SDCC project in quite some time. I regret to inform you that this is due to him losing a two year fight against cancer. Borut died last month without any of us knowing at the time, which explains the late news.
2014-11-29T04:25:35 < dongs> another dead opensores project
2014-11-29T04:26:11 < karlp> sdcc's great if you're targetting 6502...
2014-11-29T04:26:17 < karlp> oh right, no-one does...
2014-11-29T04:26:26 < dongs> apparently it does stm8 too
2014-11-29T04:26:31 < dongs> which makes it vaguely useful
2014-11-29T04:26:38 < dongs> but then again, only if youre into opensauce
2014-11-29T04:26:46 < dongs> cuz cosmic stm8 compiler works just fine..
2014-11-29T04:26:48 < gnomad> I've actually talked to several people using sdcc to generate 6502 code in th past year.
2014-11-29T04:28:04 < gnomad> I also tend to think that more than one person is working on sdcc...

2014-11-29T05:19:07 < zyp> what's your take on c vs c++ in general?
2014-11-29T05:20:24 < zyp> I don't think «big» matters
2014-11-29T05:21:29 < zyp> well, consider that C++ is mostly a superset of C
2014-11-29T05:22:05 < zyp> apart from some features that were added in C99 (notably named struct initializers), anything you can do in C can also be done in C++
2014-11-29T05:22:55 < zyp> so consider a given piece of code that will compile as both C and C++, why do you think it would be slower?
2014-11-29T05:23:14 < zyp> the code does exactly the same in both languages, so it should result in the same assembly, no?
2014-11-29T05:23:23 < zyp> exactly
2014-11-29T05:24:09 < zyp> a lot of the stuff C++ adds is compile time stuff, that doesn't really impact run time performance
2014-11-29T05:24:47 < zyp> and then you get people complaining about exception handling, which is usually turned off for microcontroller projects
2014-11-29T05:25:41 < zyp> the reason I'm using C++ is mostly because it allows me to achieve the same as I would in C, but with less and cleaner code
2014-11-29T05:26:05 < zyp> with better type safety, and so on
2014-11-29T05:27:29 < zyp> http://cgit.jvnv.net/laks/tree/usb/dwc_otg_def.h <- here's how I describe the usb registers in stm32f4
2014-11-29T05:28:01 < zyp> each register block as a struct, and then I'm grouping all register blocks into a class that gets statically instanced for each peripheral
2014-11-29T05:29:01 < zyp> the reason I'm wrapping it in a class is because it lets me do offset calculations in the constructor
2014-11-29T05:29:28 < zyp> yeah, just structs
2014-11-29T05:29:43 < zyp> in C++, structs and classes are pretty much the same
2014-11-29T05:30:03 < zyp> the only difference is that class members are private by default while struct members are public by default
2014-11-29T05:31:48 < zyp> the main argument against C++ is that it adds complexity, so it's harder to use it right than with C
2014-11-29T05:32:22 < zyp> I think that might be true on some points, but it also adds more compile time error checking
2014-11-29T05:32:30 < zyp> yeah, that's my take on it

2014-11-29T05:33:26 < zyp> kind of
2014-11-29T05:33:55 < zyp> it's more that you can make it more strict
2014-11-29T05:34:02 < zyp> consider template functions
2014-11-29T05:34:24 < zyp> in C you don't have templates, so you'd end up using macros for certain stuff instead
2014-11-29T05:34:40 < zyp> and macros doesn't have the same type safety that templates have
2014-11-29T05:35:43 < zyp> exactly
2014-11-29T05:37:16 < zyp> oh, another disadvantage with C++ would be compiler support, it's not as widely supported as C
2014-11-29T05:37:39 < zyp> I don't care, because I don't really have a reason to not use gcc
2014-11-29T05:43:35 < zyp> for arm?
2014-11-29T05:43:53 < englishman> a gift for dongs for 50 years of faithful embedded programming http://i.imgur.com/XK7fbSd.jpg
2014-11-29T05:43:54 < zyp> okay, keil is armcc
2014-11-29T05:44:25 < zyp> apart from gcc, you also have clang/llvm, which I think have usable cortex-m support by now
2014-11-29T05:44:42 < zyp> hmm, and then I guess iar does their own compiler
2014-11-29T05:45:00 < zyp> apart from that I'm not sure, I guess the rest just sells prebuilt versions of gcc
2014-11-29T05:54:07 < dongs> R2COM: crossworks but its gcc
2014-11-29T05:54:15 < dongs> IAR is i dunno, i think its ~same price as keil

2014-11-29T05:59:23 < zyp> why would you pay $1500 to use gcc?
2014-11-29T06:07:22 < gnomad> What you are paying for is support.

2014-11-29T06:15:58 < dongs> 32 vs 35C
2014-11-29T06:19:30 < zyp> hmm
2014-11-29T06:19:35 < zyp> my drives are 21C now
2014-11-29T06:20:12 < qyx_> powered off?
2014-11-29T06:20:18 < zyp> no, on

2014-11-29T06:21:10 < zyp> heh, the middle ones are warmer than the top/bottom ones
2014-11-29T06:22:37 < zyp> that's the temperatures reported by the drives themselves
2014-11-29T06:23:05 < qyx_> are you running them in the norway winter?
2014-11-29T06:23:07 < zyp> they are in hotswap trays in front of it
2014-11-29T06:23:44 < zyp> qyx_, not really winter here yet, but yeah
2014-11-29T06:24:30 < dongs> zyp, my shit is in 18C air conditioned rack
2014-11-29T06:24:40 < dongs> is your shit outside in the snow or somehting? :)
2014-11-29T06:24:44 < zyp> nah

2014-11-29T06:24:45 < qyx_> few years ago i had mine under the roof
2014-11-29T06:25:10 < qyx_> 40°C in the summer and 10°C in the winter
2014-11-29T06:25:11 < dongs> cool norco
2014-11-29T06:25:14 < zyp> it's in an uninsulated storage room though
2014-11-29T06:25:20 < zyp> yeah, it's nice
2014-11-29T06:25:30 < zyp> deeper than it needs to be, but otherwise ok
2014-11-29T06:26:17 < qyx_> ftth or what?
2014-11-29T06:26:42 < dongs> ftt rock next to your rack
2014-11-29T06:27:24 < zyp> R2COM, somewhat
2014-11-29T06:27:33 < zyp> sounds more like swedish though
2014-11-29T06:27:41 < zyp> mutilated swedish
2014-11-29T06:28:34 < zyp> qyx_, nah
2014-11-29T06:28:52 < zyp> I just were dicking around with fibre channel before
2014-11-29T06:29:09 < qyx_> o\
2014-11-29T06:29:15 < zyp> the bottom cabinet in the picture is a fibre channel enclosure
2014-11-29T06:29:21 < qyx_> too pro
2014-11-29T06:29:34 < qyx_> i realized that ftth won't be multimode
2014-11-29T06:29:38 < zyp> :p
2014-11-29T06:30:11 < zyp> the raid controller in the enclosure doesn't support higher raid levels than 5 though
2014-11-29T06:30:19 < zyp> and 2Gb/s FC isn't really that fast
2014-11-29T06:30:55 < qyx_> yep, i was also playing with some refurbished fc storage
2014-11-29T06:31:19 < qyx_> not really worth the power it draws
2014-11-29T06:31:35 < zyp> I pay a fixed sum for power
2014-11-29T06:31:52 < zyp> i.e. it's part of the fixed rent
2014-11-29T06:32:39 < zyp> because people is too cheap to install individual meters
2014-11-29T06:34:43 < qyx_> even uncalibrated meters are quite expensive here
2014-11-29T06:34:50 < qyx_> last time i bought one it was like ~150e

2014-11-29T08:55:20 < qyx_> I don't know, onboard usb hub reports too much EMI saying it is resetting the port
2014-11-29T08:57:01 < decimad2> Maybe it's right ;)
2014-11-29T08:57:54 < decimad2> But isn't usb differential?
2014-11-29T08:58:21 < decimad2> Probably not drilled, so the loop can catch a voltage? hrmmm
2014-11-29T09:01:40 < madist> dongs smd resistors have a different code. 51 is the resistance and K is the tolerance.
2014-11-29T09:03:46 < decimad2> madist: So 51 means 500 kilo-ohm?
2014-11-29T09:04:10 < madist> decimad2: ignore what I said. I didn't read what dongs said later.
2014-11-29T09:04:40 < madist> decimad2: http://2.bp.blogspot.com/-t8fta6BqvHA/UjBz-2joCbI/AAAAAAAAAeI/LKan_82hvQQ/s1600/r22.png
2014-11-29T09:05:04 < madist> ^ that's the 2 digit code. this is the tolerance: http://2.bp.blogspot.com/-6yzPcXx0fxo/UjB0Sqx-NvI/AAAAAAAAAeQ/0bznxBaAMmY/s1600/r23.png
2014-11-29T09:05:13 < madist> (there is no K.)
2014-11-29T09:05:34 < decimad2> madist: thanks, but where to get a scaling exponent from the code?
2014-11-29T09:05:46 < madist> decimad2: the second pic I posted.
2014-11-29T09:05:56 < madist> not tolerance, multiplier. :p
2014-11-29T09:08:17 < decimad2> madist: thank you. I digged further, there seem to be multiple encodings around... hrmmm
2014-11-29T09:08:44 < madist> decimad2: there is a standard. somehow it seems there is no wikipedia page for it. EIA-96.
2014-11-29T09:09:57 < decimad2> madist: from what I can grasp, 51K should mean 50 kOhm (10%)
2014-11-29T09:10:15 < decimad2> np, actually it should just mean 50 Ohm
2014-11-29T09:10:33 < madist> there is no K.
2014-11-29T09:10:59 < madist> 51 means the significant digits is 332.
2014-11-29T09:11:53 < madist> so 51B for example means 332 * 10^1 = 3320 ohms.
2014-11-29T09:12:10 < madist> 51C = 332 * 10^2 = 33.2k
2014-11-29T09:12:57 < madist> X=10-1, Y=10-2, A=100, B=101, C=102, D=103, E=104, F=105
2014-11-29T09:13:26 < madist> X=10-1, Y=10-2, A=10^0, B=10^1, C=10^2, D=10^3, E=10^4, F=10^5
2014-11-29T09:14:09 < akaWolf> awwwww
2014-11-29T09:14:12 < decimad2> I trusted that dongs resistor has 51K printed on it
2014-11-29T09:14:22 < madist> never trust anything dongs says.
2014-11-29T09:14:49 < madist> besides, I think he said it was written on the page, not on the resistor.
2014-11-29T09:15:37 < decimad2> oh, yes... but why would you specify 510 kOhm? It can never be that exact, isn't 500 more reasonable?
2014-11-29T09:16:56 < madist> decimad2: http://en.wikipedia.org/wiki/Preferred_number#E_series
2014-11-29T09:18:14 < decimad2> Okay, I should have been able to explain that to myself :( thanks again

2014-11-29T10:50:02 < decimad2> 0603 is too much for a beginner, right? If I were to design a customt board, I should use 0805 minimum?
2014-11-29T10:51:05 < decimad2> hand-assembly obviously ;)
2014-11-29T10:51:53 < decimad2> would be cool if there were empty packages sold just to practice soldering the stuff ;)
2014-11-29T10:55:35 < madist> 1206 and larger you can do without special tools.
2014-11-29T10:55:46 < madist> anything smaller and you need a magnifier/viewer.
2014-11-29T10:56:02 < madist> I don't think the difference between 0603 and 0805 is significant.
2014-11-29T10:58:06 < decimad2> Well I have access to a magnifier, but I have somewhat shaky hands... especially after coffee ;)

2014-11-29T14:30:53 < karlp> zyp: in your usb dwc_otg_def.h you linked earlier, the reserved and reserved1 in DWC_OTG_reg_t, those contribute to the runtime memory size of those structures right?
2014-11-29T14:31:14 < dongs> im not zup but I would imagine so
2014-11-29T14:32:02 < karlp> and in DWC_OTG_fifo_reg_t, the 4k fifo there, that maps to the 4k virtual ram per EP fifo right? even though that's shared fifo space?  How does that stuff work such that you don't end up with that 4k on heap?

2014-11-29T14:43:44  * karlp shrugs.  0805 is fine too, but 1206 is just enormous when you actually put them down
2014-11-29T14:43:52 < karlp> might as well use through hole.
2014-11-29T14:44:17 < karlp> 0603 gives you way mor eoptions for bypass caps for instance, and fuck having multiple sizes on the same board
2014-11-29T14:45:24 < decimad2> Okay, I will consider this seriously

2014-11-29T14:48:51 < karlp> hey dongs, that hdmi pi thing, why would I use that instead of the hdmi on board? I thought you were adding displayport or some other shit?
2014-11-29T14:49:36 < karlp> 99c. nice one.
2014-11-29T14:49:42 < karlp> I wonder how much they charge for shipping
2014-11-29T14:51:27 < dongs> karlp: its not really pi speecific its hdmi>displayport lcd + hdmi audio

2014-11-29T15:50:35 < __tylerdurden> scrts : i want to implement sleep mode in freertos and i want to wake up with timer interrupt but the PWR_EnterSleepMode function doc says the MCU wakes up with external port interrupt , no idea how to wake it up by timer interrupts.
2014-11-29T15:50:58 < scrts> maybe you need different sleep mode then?
2014-11-29T15:56:04 < dongs> __tylerdurden: then use WFI() or something?
2014-11-29T15:56:16 < dongs> or like he says, theres sleep modes that w ake up by interupot
2014-11-29T15:56:26 < dongs> but if you have rtos, youre gonna have systick wakeup every 1kHz anyway...
2014-11-29T15:59:42 < __tylerdurden> the other sleep mode need a function to be called to wake up from sleep , and the other low power mode with WFI()  switches off flashmemory
2014-11-29T15:59:53 < dongs> um
2014-11-29T15:59:58 < dongs> wfi never switches off flash
2014-11-29T16:03:02 < __tylerdurden> yes wfi wakes up teh MCU without any issues , but the LP sleep mode which uses wfi to wakeup , switches off flashmem while sleep , so how it effects the timers which i'm running in the background
2014-11-29T16:03:07 < __tylerdurden> have any idea
2014-11-29T16:03:19 < dongs> you can just call wfi() somewehre  and it'll sit there waiting.
2014-11-29T16:03:23 < dongs> like in one of your threads or something.
2014-11-29T16:03:31 < dongs> until next systick probably
2014-11-29T16:05:03 < qyx_> you either have low power mode or you have your peripherals running
2014-11-29T16:05:33 < qyx_> if you want cpu & timers to run, use wfi
2014-11-29T16:05:56 < qyx_> or low power run mode if it is enough
2014-11-29T16:11:20 < karlp> there's whole chapters in the ref manuals on this, and even the factory example firmware on the l151 discovery board had examples of the different modes
2014-11-29T16:18:24 < __tylerdurden> ok thanks...i checked the examples on stm32l152D_eval board... all the sleep egs are provided for RAM ....had hard time to figure out to load it in flash ...how to convert it so that it can be loaded in flash
2014-11-29T16:19:06 < __tylerdurden> i selected the stm32l1xx_flash.icf file for linker config but no use
2014-11-29T16:19:19 < __tylerdurden> any idea?
2014-11-29T16:19:57 < __tylerdurden> and selected the boot pins to flash too

2014-11-29T20:32:45 < zyp> karlp, yes, the reserved ones are padding for addrs that doesn't contain any registers
2014-11-29T20:34:14 < zyp> I'm not sure how you imagine anything can end up on the heap, considering I don't even have a heap
2014-11-29T20:34:32 < zyp> so I'm assuming you mean global memory, i.e. .data or .bss instead
2014-11-29T20:35:36 < zyp> but the thing is that I'm not instancing any of those structs anywhere, so they aren't allocated from anywhere
2014-11-29T20:35:52 < karlp> they're not instanced at all?
2014-11-29T20:35:58 < zyp> correct
2014-11-29T20:36:22 < zyp> DWC_OTG_t only contains references or pointers to those structs, which are initialized with the address
2014-11-29T20:36:39 < zyp> so the code simply expects it to exist at that location
2014-11-29T20:37:36 < zyp> I'm using references for single blocks and pointers for arrays of blocks
2014-11-29T20:37:42 < karlp> yeah, didn't mean heap, stack I guess, but I thouight they were being instanced.
2014-11-29T20:37:53 < karlp> does arcin use this? or any other example I can look at?
2014-11-29T20:38:13 < karlp> I still don't get how your refs work, but that's me and c++ that need to work together more.
2014-11-29T20:38:16 < zyp> «this» being what in particular?
2014-11-29T20:38:24 < karlp> like the 4k fifo union
2014-11-29T20:38:48 < zyp> a reference is essentially the same as a constant pointer, i.e. you can't change it after initializing it with a value
2014-11-29T20:39:03 < zyp> the difference is that a reference doesn't have to be explicitly dereferenced
2014-11-29T20:39:04 < karlp> and so even i the first one, wit hthe reserved blocks, if they're not instanced, how are you using them?
2014-11-29T20:39:28 < karlp> does c++ let you say at compile time, this struct is at offset x, and then you just use the fields in it, so that all collapses down to compile time constants?
2014-11-29T20:39:44 < zyp> that's exactly what I does
2014-11-29T20:40:03 < karlp> right, that's the bit I havne't figured out yet :)
2014-11-29T20:40:14 < zyp> DWC_OTG_t is instanced, so worst case it consumes 20B of .rodata
2014-11-29T20:40:22 < zyp> for the pointers/references
2014-11-29T20:40:33 < zyp> I'm instancing at OTG_FS and OTG_HS
2014-11-29T20:40:33 < karlp> it's all this sort of stuff that sounds very appealing about c++, but I don't understand it enough.
2014-11-29T20:40:46 < zyp> and then I can access registers as OTG_FS.reg.GUSBCFG, for instance
2014-11-29T20:41:11 < zyp> and OTG_FS.fifo[0].reg
2014-11-29T20:41:58 < karlp> so the constructur bit, line 78 or so, that's c++ magic collapsing the structs into just constant addresses.
2014-11-29T20:42:39 < zyp> eh, it's not really different from initializing a struct of pointers to other structs
2014-11-29T20:42:53 < karlp> so, the fifo bit, with 4k, how does that get used? those are 4k virtual areas per endpoint or something? but it's only 1.25k of real ram? Or am I not understanding the usb device at all
2014-11-29T20:43:14 < karlp> yeah, I kinda get the idea of it, just not used to reading it, and certainly wouldn't have been able to write it.
2014-11-29T20:43:30 < karlp> I would have ended up with C with c++ syntax and maybe namespaces at best.
2014-11-29T20:43:53 < zyp> the fifo area contains 4k of addrs for each endpoint, since it's a fifo, writing any of the 1024 addrs in an area is equivalent
2014-11-29T20:44:12 < zyp> the register definition class is really only used from the driver class, not any of the projects using it
2014-11-29T20:44:17 < zyp> i.e. from this: http://cgit.jvnv.net/laks/tree/usb/dwc_otg.h
2014-11-29T20:44:44 < zyp> this takes a reference to DWC_OTG_t and stores it in the otg member variable
2014-11-29T20:45:06 < zyp> so otg references either OTG_FS or OTG_HS depending on what it was initialized with
2014-11-29T20:46:52 < karlp> so, where does the buf[1024] get used?
2014-11-29T20:47:21 < zyp> I don't use it
2014-11-29T20:47:40 < karlp> it's just there to make the reg address at the right offset!
2014-11-29T20:47:42 < karlp> ah, magic.
2014-11-29T20:47:44 < karlp> that makes sense
2014-11-29T20:48:00 < zyp> writing to buf[1] is equivalent to writing to buf[0], and buf[0] is an alias of reg, since it's an union
2014-11-29T20:48:14 < zyp> I could also make it a struct with a reserved[1023]
2014-11-29T20:49:18 < karlp> hrm, need to have  play with this more.
2014-11-29T20:49:22 < karlp> thanks for the answers
2014-11-29T20:49:24 < zyp> I believe the point of making the fifo like that is that you can use memcpy or other functions incrementing the addr to read and write the fifo
2014-11-29T20:50:25 < zyp> dwc_otg is probably not the easiest example of how I'm using C++ to describe registers :p

2014-11-30T05:28:27 < dongs> ive never seen it

2014-11-30T05:29:02 < Lux> like a ground loop via mains
2014-11-30T05:30:23 < Lux> and i think issues mostly arrise at high currents, when enough voltage drops on the ground wires/traces with normal dc stuff

2014-11-30T07:51:53 < englishman> what is the point of hacking a psu
2014-11-30T07:52:24 < dongs> just enables some options

2014-11-30T07:52:41 < upgrdman> ya. google "riglol"
2014-11-30T07:52:54 < upgrdman> riglol makes it trivial to hack a bunch of rigol stuff

2014-11-30T07:56:24 < dongs> my shit is all analog dials
2014-11-30T07:56:41 < englishman> $400 for 3A is super meh
2014-11-30T07:57:05 < upgrdman> its supposed to be super low noise
2014-11-30T07:57:14 < dongs> yes I looked at http://www.pololu.com/product/2589 but I was afraid it would come wiht a clean code manual on CD
2014-11-30T07:57:18 < ReadError> my korad shit has usb/rs232 but never tried it
2014-11-30T07:57:38 < dongs> plus it was a byproduct of dickstarter
2014-11-30T07:57:42 < upgrdman> clean code manual?
2014-11-30T07:57:43 < dongs> where "early birds" paid $189/ea
2014-11-30T07:59:07 < upgrdman> the early bird gets ... dick in the ass?
2014-11-30T07:59:18 < dongs> basically
2014-11-30T07:59:50 < upgrdman> packed pixels got funded.
2014-11-30T07:59:56 < dongs> yeah sadly
2014-11-30T08:00:08 < upgrdman> i hope they succeed. i was tempted to buy a pair.
2014-11-30T08:00:13 < upgrdman> but didn't want to risk it
2014-11-30T08:00:14 < dongs> now i'll just say "I told you so" when they dont deliver
2014-11-30T08:00:33 < upgrdman> why don't you think they'll deliver?
2014-11-30T08:00:34 < dongs> upgrdman: ? you can already buy same shit elsewehre
2014-11-30T08:00:52 < upgrdman> dongs: i dont want to DIY a shitty case and dual mount
2014-11-30T08:01:00 < dongs> ha ha ha
2014-11-30T08:01:22 < dongs> well, good luck. they won't deliver because its some one dude who runs an IT solutions shop
2014-11-30T08:01:36 < upgrdman> ya. that's why i didn't dickstart him
2014-11-30T08:01:54 < dongs> he talks about injection molding, FCC/CE certifications and other lols
2014-11-30T08:01:55 < upgrdman> never trust a dude with a ghetto 3d printer.
2014-11-30T08:02:14 < dongs> the mold for that will cost $50k for 2 parts (brackets and enclosure) and im being generous here
2014-11-30T08:02:25 < dongs> never mind 10-20k for fcc/ce assuming he doesnt fail it
2014-11-30T08:03:19 < upgrdman> why can't tablet makers do hdmi in. :(
2014-11-30T08:03:27 < upgrdman> the DSLR guys would all jizz themselves over it too
2014-11-30T08:03:47 < englishman> google cant even manage SD card, how are they gonna do hdmi
2014-11-30T08:05:06 < dongs> upgrdman: 10" is too big for jewslr?

2014-11-30T08:06:07 < dongs> upgrdman: k, i already had that in mind for my hdmi interface stuff
2014-11-30T08:06:27 < upgrdman> ReadError: analog discovery might be way better. esp if you're a us student. same price then.
2014-11-30T08:07:03 < upgrdman> dongs: what're you planning? hdmi in -> usb for tablets with otg?
2014-11-30T08:07:17 < dongs> upgrdman: well, no need to plan that, already exists
2014-11-30T08:07:28 < dongs> no, but < 10" panels with hdmi in.
2014-11-30T08:07:34 < upgrdman> ah
2014-11-30T08:11:01 < dongs> https://www.switch-science.com/catalog/2027/ holy shit why is this $4000

2014-11-30T08:11:42 < dongs> i dont want  it
2014-11-30T08:11:47 < upgrdman> does .jp heavily tax imports?
2014-11-30T08:11:48 < dongs> im looking at local stonershop
2014-11-30T08:11:56 < dongs> upgrdman: no theyt just come up with retarded prices for things
2014-11-30T08:12:01 < upgrdman> o
2014-11-30T08:12:10 < zyp> i.e. importers want money too
2014-11-30T08:12:16 < zyp> same thing in norway
2014-11-30T08:12:32 < dongs> Etharnet
2014-11-30T08:12:43 < upgrdman> zyp: are you guys able to work about them by buying online for us/elsewhere?
2014-11-30T08:12:48 < upgrdman> s/for/from
2014-11-30T08:13:24 < zyp> well, yes
2014-11-30T08:13:49 < zyp> actually, part of the thing is norwegian 25% sales tax, which is due on imports too
2014-11-30T08:14:03 < zyp> japanese sales tax is only 8%
2014-11-30T08:14:13 < zyp> so that's not entirely comparable
2014-11-30T08:14:30 < upgrdman> 25%... damn :( that sucks
2014-11-30T08:14:31 < dongs> but zyp doens't pay tax on shit he gets from me
2014-11-30T08:14:36 < dongs> i think
2014-11-30T08:14:56 < upgrdman> commercial invoice listing "samples" ? :)
2014-11-30T08:14:59 < zyp> mostly not, depends how it's declared on the box
2014-11-30T08:15:10 < dongs> i've always wondered hwo the fuck would stuff work if everyone paid tax for stuff
2014-11-30T08:15:17 < dongs> like I'd send 10k worth of components to assembler
2014-11-30T08:15:21 < dongs> they paid tax on full value
2014-11-30T08:15:26 < dongs> then send me assembled stuff
2014-11-30T08:15:29 < dongs> at full value
2014-11-30T08:15:31 < dongs> and etc
2014-11-30T08:15:35 < zyp> no
2014-11-30T08:15:39 < dongs> how the fuck would anyone be able to sell stuff reasonably then? :)
2014-11-30T08:15:57 < dongs> zyp, no what? but thats how it *should* be, no?
2014-11-30T08:16:10 < zyp> no, tax is only paid once
2014-11-30T08:16:23 < upgrdman> isn't that the point of a VAT? taxing the added value at each step?
2014-11-30T08:16:32 < zyp> yes, only the added value
2014-11-30T08:16:34 < dongs> zyp, then who pays "tax" on assembled PCBs?
2014-11-30T08:17:51 < dongs> when digijew sends those fucking JST connectors, my place has to pay import tax on them
2014-11-30T08:17:58 < zyp> the norwegian system works like you can subtract tax you've paid from tax you have to collect
2014-11-30T08:18:17 < dongs> but they're not evne end-user
2014-11-30T08:18:31 < dongs> and if its sent back to you at full value
2014-11-30T08:18:36 < dongs> then you end up paying tax for that, too
2014-11-30T08:18:45 < dongs> i think this stuff is just bullshit
2014-11-30T08:20:14 < zyp> if a company buys something for 500 and sells it for 1000, tax included in both, you subtract tax paid on the first from tax paid on the second before paying the tax authority
2014-11-30T08:21:07 < zyp> which in the end means that you only pay tax for the added value, i.e. the new 400+100tax
2014-11-30T08:21:25 < dongs> but this is later?
2014-11-30T08:21:30 < dongs> like at your end of year reporting or someshit?
2014-11-30T08:21:46 < dongs> because delivery courier and shit is gona want all this stuff paid upfront
2014-11-30T08:22:05 < zyp> yeah, you pay tax on shit you buy and collect tax in full on shit you sell, and then just calculate the difference when reporting
2014-11-30T08:22:45 < englishman> there lies the difference between consumption tax and vat
2014-11-30T08:22:47 < zyp> this applies to all purchases and sales for a tax registered company, so even company equipment can be purchased tax free that way
2014-11-30T08:23:41 < zyp> englishman, what difference?
2014-11-30T08:23:59 < englishman> consumption tax only taxes those who use
2014-11-30T08:24:11 < englishman> i.e. buy components -> assemble -> sell -> no tax
2014-11-30T08:24:17 < zyp> well, it works out the same in the end
2014-11-30T08:24:17 < englishman> vat taxes the assembling
2014-11-30T08:24:32 < englishman> ya, govt gets their cut sure, but it chagnes who is taxed
2014-11-30T08:24:56 < dongs> im assburgering all day today
2014-11-30T08:25:00 < dongs> should probly do something
2014-11-30T08:25:13 < upgrdman> *assburglering
2014-11-30T08:25:30 < zyp> englishman, no, it doesn't, the total tax collected is a fixed percentage of the final sales price
2014-11-30T08:25:58 < englishman> well i dono too much about how euro vat works
2014-11-30T08:26:19 < englishman> just about the taxes where i am
2014-11-30T08:26:21 < zyp> to put it in a different way, everybody pays tax, but every intermediate step is reimbursed
2014-11-30T08:27:28 < zyp> part of the tax collected in each step reimburses the tax collected in the previous step, so in the end, the final tax collection reimburses all the previous ones
2014-11-30T08:27:28 < englishman> so here if a company buys say computers to innovate on they gotta pay sales tax
2014-11-30T08:27:44 < zyp> right
2014-11-30T08:27:48 < englishman> as they are the end users
2014-11-30T08:27:56 < englishman> so its the same?
2014-11-30T08:28:01 < zyp> they don't have to here, since all purchases can be reimbursed
2014-11-30T08:28:07 < englishman> all purchases?
2014-11-30T08:28:47 < zyp> yes, the system doesn't distinguish between purchase of tools and purchase of materials for production
2014-11-30T08:29:00 < englishman> cool
2014-11-30T08:29:15 < englishman> i guess corporate income tax is higher as a result?
2014-11-30T08:29:30 < zyp> might be, I haven't looked much into that
2014-11-30T08:32:00 < zyp> I'm not sure how it'll work out for a company that mainly does exports though
2014-11-30T08:32:34 < zyp> exports aren't subject to tax, so you don't collect anything from them
2014-11-30T08:33:00 < zyp> so I guess you could essentially end up with a negative value in the tax report
2014-11-30T08:33:14 < dongs> i didnt know that japan post international mail wasnt subject to taxing
2014-11-30T08:33:23 < dongs> when japs went to 8% from 5% i thought i'd have ot dick around with rates in my shop
2014-11-30T08:33:35 < dongs> but apparently EMS / international post was never taxed in teh first place
2014-11-30T08:34:15 < zyp> yeah, because tax applies in the country it's sold to, not from
2014-11-30T08:35:26 < upgrdman> anyone here experienced with java swing? if you put all of your event handlers in your jframe class it gets fucking huge and unmaintainable. what's a good way to deal with this? make another class in the same package that defines and adds "listeners"?
2014-11-30T08:35:40 < zyp> best way is to not use swing
2014-11-30T08:35:47 < dongs> was just typing that
2014-11-30T08:35:50 < dongs> who teh fuck uses that shit in 2014
2014-11-30T08:35:52 < upgrdman> ya... it's for a uni assignment
2014-11-30T08:35:58 < upgrdman> so not my pick
2014-11-30T08:36:01 < zyp> heh
2014-11-30T08:36:08 < zyp> oh, that takes me back
2014-11-30T08:36:19 < zyp> I also had a mandatory java course
2014-11-30T08:36:32 < dongs> my college was before java
2014-11-30T08:36:42 < dongs> mandatory course was like MIPS asm
2014-11-30T08:36:47 < upgrdman> the cs curriculum here is all java, one c++ class, and two verilog/fpga classes.
2014-11-30T08:37:01 < upgrdman> oh, and 8051 asm
2014-11-30T08:37:06 < zyp> so I asked the prof «hey, are we allowed to use other libs for the assignments?» «sure, just make sure to bundle the lib so it'll run»
2014-11-30T08:37:18 < zyp> so I did every fucking gui assignment with qt jambi
2014-11-30T08:37:23 < upgrdman> :)
2014-11-30T08:37:34 < upgrdman> im working in a group, and my group mates don't really know shit
2014-11-30T08:37:42 < upgrdman> so im fucked :( doing ~all of the project
2014-11-30T08:37:53 < zyp> that's good, that makes them easy to convince to do it your way
2014-11-30T08:38:06 < upgrdman> prof says use java
2014-11-30T08:38:21 < zyp> qt jambi is java bindings for qt
2014-11-30T08:38:28 < upgrdman> but ya, at least i dont have to try to interpret the trash they call code
2014-11-30T08:38:32 < dongs> http://www.gefen.com/kvm/dcable.jsp?prod_id=9070
2014-11-30T08:38:45 < upgrdman> well too late now. project half done, and i dont know shit about qt
2014-11-30T08:38:56 < zyp> ok, I guess that's worse
2014-11-30T08:39:30 < upgrdman> it's a stupid ass music player. like a clone of iTunes
2014-11-30T08:39:47 < zyp> oh, I remember we did that too
2014-11-30T08:39:59 < upgrdman> prof basically says "implement this shit" ... in three iterations. we're on iteration 3 of 3 now :)
2014-11-30T08:40:03 < zyp> I remember people were dicking around with some shitty mp3 player lib
2014-11-30T08:40:32 < zyp> and I just instanced the mediaplayer class in qt's phonon lib
2014-11-30T08:40:40 < upgrdman> one of my friends is taking the same course but a different prof, he gets to make a game. im stuck making some shitty mp3 player
2014-11-30T08:40:55 < dongs> solution:
2014-11-30T08:41:03 < upgrdman> my friend make a version of Asteroids. but with Doge instead of asteroids. lolol
2014-11-30T08:41:04 < dongs> make a hidden flappy bird game
2014-11-30T08:41:05 < dongs> inside mp3 player
2014-11-30T08:41:10 < dongs> activated by keypress/click
2014-11-30T08:41:16 < upgrdman> not a bad idea, but too lazy
2014-11-30T08:41:20 < zyp> and since it were only another ten lines or so, I attached a video output widget to the media player to turn it into a video player too
2014-11-30T08:41:33 < dongs> i think i remember youblogging this zyp
2014-11-30T08:41:41 < upgrdman> been spending most of my free time learning verilog and dicking with a spartan3e
2014-11-30T08:42:11 < dongs> when are you gonna know enough to be hireable to do my verilog projects
2014-11-30T08:42:15 < qyx_> lol
2014-11-30T08:42:25 < upgrdman> got vga and ps2 working on the dev board. tempted to have my fpga draw a big penis.
2014-11-30T08:42:27 < qyx_> hm, i used lua + wxwidgets at uni

2014-11-30T14:25:41 < decimad> Is there some way I cannot see, to use the stm timers for SVPWM? My intuition is I would actually need four comparators and three outputs on a timer or would need to allocate many synchronized timers...
2014-11-30T14:30:26 < Tectu_> wtf is SVPWM?
2014-11-30T14:32:23 < decimad> space vector pulse width modulation for 3 phase rectifiers
2014-11-30T14:33:36 < decimad> in the end you basically switch between a combination of four 3 bit values at calculated times per cycle
2014-11-30T14:34:43 < decimad> well, give or take considering the switching strategy, but that combination is popular
2014-11-30T14:38:07 < decimad> So my current plans are that I do the calculations and stuff on the mcu, but do the ad conversion interface (need exact sample times) and pwm cycle execution on a connected fpga... Obviously that's pretty "complicated"...

2014-11-30T18:22:47 < dongs> 4.5k for a case + lcd + front panel is pretty gay
2014-11-30T18:23:25 < emeb_mac> yep. it's spare parts now. not worth more than a few hundred.
2014-11-30T18:23:50 < dongs> i'll best offer him 100 bucks just for lols
2014-11-30T18:26:55 < dongs> Note:Since this is missing all the actual "scope" parts, $100 is the best I can offer. Maybe I'll reuse the keyboard matrix and LCD with an arduino to make it some kinda home automation controller.

2014-11-30T18:37:41 < mitrax> on the STM32F429 discovery board the lcd frame buffer is usually located at the start of the SDRAM, anything beyond that address (0xD0000000) + the memory required for the 2 layers should be free right or will this conflict with something else? i'd like to use the remaining memory for a heap
2014-11-30T18:38:19 < emeb_mac> I've used the memory beyond the frame buffer for audio data. works fine.
2014-11-30T18:38:34 < emeb_mac> pretty cool if the audio data DMA buffer is in the LCD buffer though.
2014-11-30T18:39:15 < mitrax> is there a performance penalty for using the sdram instead of the internal ram? (as long as i don't execute any code from the sdram)

2014-11-30T19:24:30 < bvernoux> Steffanx: Why I will be totally happy ;)
2014-11-30T19:24:47 < bvernoux> esp8266 is pretty limited alone but it can be interesting
2014-11-30T19:26:12 < Steffanx> dunno, i would expect you to be happy. Didn't you like micropython?
2014-11-30T19:36:38 < emeb_mac> mitrax: of course there's a penalty for using sdram - access time is much slower than on-chip SRAM.
2014-11-30T19:37:13 < emeb_mac> and if the display is running at the same time there will be arbitration as well.

2014-11-30T20:29:08 < decimad> guys, what would be my best bet to measure a bipolar current (-10A <= I <= 10A)? Obviously need to go shunt-based. Set up a circuit with OpAmp and AD converter... But obviously I need symmetric voltages and so many parts. Is there some ic that would integrate all that with control over when to sample? I found some ics which are supposed to monitor the power, but they were rather slow and I don't need power, only current
2014-11-30T20:31:21 < Lux> just get one of those allegro sensors and be done with it

2014-11-30T21:45:59 < decimad> it allocates more space for the heap and gets called when you use printf and stuff
2014-11-30T21:46:03 < Steffanx> libnosys comes with a implementation of sbrk.

2014-11-30T21:48:08 < Steffanx> perhaps also tell your linker/compiler to use newlib-nano using --specs=nano.specs ? ( im not sure if that's required though )
2014-11-30T21:50:20 < decimad> yes, mine does
2014-11-30T21:51:32 < decimad> can you get gcc to output the file libraries it opens with full path?
2014-11-30T21:53:37 < decimad> -print-file-name=library
2014-11-30T21:53:50 < decimad> and then nm on that file, if it is the correct one at all
2014-11-30T21:54:04 < Tekkkz> so how can i solve my problem now?
2014-11-30T21:55:40 < decimad> try gcc -print-file-name=libnosys.a, see to which file it gets you and then check with "nm thatfile" if it defines _sbrk
2014-11-30T21:56:34 < Steffanx> arm-none-eabi-gcc*
2014-11-30T21:57:23 < Tekkkz> and then?
2014-11-30T21:58:02 < Tekkkz> how can i include this lib?
2014-11-30T21:59:22 < Tekkkz> gcc -print-file-name=libnosys.a returned gcc -print-file-name=libnosys.a
2014-11-30T21:59:28 < Tekkkz> and what should i do then?
2014-11-30T22:00:56 < decimad> dude, it should return a file path, not your echo'ed command
2014-11-30T22:01:41 < Tekkkz> it retourn the filename
2014-11-30T22:02:18 < decimad> now you check with "nm that file path" if it defines _sbrk
2014-11-30T22:03:04 < Tekkkz> but i dont know file path
2014-11-30T22:03:12 < Tekkkz> it dont return file path, it return filename
2014-11-30T22:03:25 < qyx_> copy&paste what you did
2014-11-30T22:03:32 < qyx_> i mean, pastebin it
2014-11-30T22:03:38 < Tekkkz> ok
2014-11-30T22:03:54 < Steffanx> use arm-none-eabi-gcc not gcc, Tekkkz
2014-11-30T22:04:02 < Tekkkz> ahh kk
2014-11-30T22:04:20 < Steffanx> decimad, you should be more precise :P
2014-11-30T22:04:20 < Tekkkz> yeah now i have file path
2014-11-30T22:04:39 < decimad> automatisms... :(
2014-11-30T22:04:51 < Tekkkz> an now i do nm /home/martin/Software/gcc-arm-none-eabi-4_8-2014q3/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/lib/libnosys.a

2014-11-30T22:05:58 < Tekkkz> yes
2014-11-30T22:06:11 < Tekkkz> btw, there is _sbrk at the nm command

2014-11-30T22:54:28 < decimad> so what was wrong?
2014-11-30T22:54:31 < decimad> :)
2014-11-30T22:56:46 < PaulFertser> decimad: lack of explicit -lc
2014-11-30T22:56:59 < PaulFertser> decimad: plus ld file slightly incompatible with newlib.
2014-11-30T22:57:28 < Steffanx> My turn for (stupid) questions. Why -lc is required? Why -lnosys wasnt enough?
2014-11-30T22:59:37 < Steffanx> I thought it's libnosys is the lib that has implementations for the system calls
2014-11-30T23:00:00 < PaulFertser> Steffanx: afaict libc is linked implicitly after all your sources listed at the command line. But newlib libc needs some symbols that are usually provided by RTOS or the nosys library. Even if you list it last on the command line it's still getting linked before libc. So its symols are not used to resolve what's missing in libc.

2014-11-30T23:43:17 < PaulFertser> decimad: "gold" linker was written in C++ by googlers in 2003, and it looks like it has the same order-dependent linking scheme, at least its man page lists start/end-group.
2014-11-30T23:44:18 < decimad> PaulFertser: Maybe they had compatibility in mind?
