2015-09-01T00:28:48 < upgrdman> hmmm http://www.geek.com/chips/15-pc-makes-the-raspberry-pi-look-expensive-1632604/
2015-09-01T00:30:28 < upgrdman> $19 shipped, seems much better than a pi
2015-09-01T00:31:06 < Sync_> but you have to deal with the allwinner bullshit
2015-09-01T00:31:28 < kakimir> does it even have rtc
2015-09-01T00:32:00 < Sync_> who needs a rtc when you have ntp
2015-09-01T00:32:57 < upgrdman> whats wrong with allwiner stuff?
2015-09-01T00:34:26 < kakimir> when you want to utilize it for shiet without internet accesss?
2015-09-01T00:35:10 < upgrdman> kakimir, then use an external rtc. it seems like most apps for SBCs are net-connected
2015-09-01T00:35:41 < artag> you don't always need an rtc either
2015-09-01T00:35:42 < kakimir> it's still gay
2015-09-01T00:36:12 < artag> if you care about time of day, run a pll against light level
2015-09-01T00:36:34 < kakimir> sweeet

2015-09-01T00:38:20 < upgrdman> kinda wish it used usb for power. who the f wants to buy a power brick for the SBC when damn near everything has a usb port or usb "charger"
2015-09-01T00:38:37 < upgrdman> 5v2a is doable with over usb
2015-09-01T00:38:45 < kakimir> I don't need but potential application may require logging of production or such with somewhat correct timestamp
2015-09-01T00:39:10 < upgrdman> so buy a $2 rtc dongle from ebay or ali
2015-09-01T00:39:27 < kakimir> no I made my own 20$ rtc
2015-09-01T00:39:29 < upgrdman> im sure theres tons for the dingleberry pi market
2015-09-01T00:40:21 < Lux> there is, but you have to dick around a bit to get it running under linux
2015-09-01T00:40:40 < kakimir> yes
2015-09-01T00:40:57 < kakimir> and not too little to make proper scripts and shiet
2015-09-01T00:41:16 < Lux> and it looks like they are busy on getting all the allwinner patches mainline
2015-09-01T00:41:20 < kakimir> service scripts turn off some stuff
2015-09-01T00:41:43 < Lux> so i guess the support will get better
2015-09-01T00:42:00 < kakimir> and make installation script for getting it working in multiple devices without hassle

2015-09-01T00:51:46 < kakimir> you can count days how long it takes for someone without understanding of udev rules, service scripts, linux system clock or bash scripting for creating installation script
2015-09-01T00:51:53 < kakimir> to make it proper

2015-09-01T00:56:14 < kakimir> you can make it dirty in 15minutes sure
2015-09-01T00:57:21 < upgrdman> seems like it's a solved problem
2015-09-01T00:57:24 < upgrdman> e.g. http://thepihut.com/blogs/raspberry-pi-tutorials/17209332-adding-a-real-time-clock-to-your-raspberry-pi
2015-09-01T01:00:16 < kakimir> does it keep time synced?
2015-09-01T01:01:08 < upgrdman> it's an rtc. wtf do you think?
2015-09-01T01:01:21 < upgrdman> read the last paragraph on that page
2015-09-01T01:01:52 < kakimir> yes
2015-09-01T01:02:05 < kakimir> but does it keep actual rtc time corrected?
2015-09-01T01:02:43 < kakimir> if there is ntp in use or user adjusts clock
2015-09-01T01:06:11 < kakimir> what is seen does only one direction

2015-09-01T02:30:39 < zyp> kakimir, uh, it registers it as the system hw clock, so the system takes care of keeping it synced
2015-09-01T02:31:15 < dongs> lannix
2015-09-01T02:31:29 < kakimir> what exactly registers is?
2015-09-01T02:31:53 < dongs> adds to the system as a clock source.
2015-09-01T02:32:08 < dongs> tells kernel "hey there's this shit on i2c that has correct time, all the time"
2015-09-01T02:32:12 < kakimir> what system
2015-09-01T02:32:17 < dongs> lunix kernel
2015-09-01T02:32:25 < kakimir> does lunix kernel give a shit?
2015-09-01T02:32:28 < dongs> yes
2015-09-01T02:32:40 < kakimir> how you know all this?
2015-09-01T02:32:46 < dongs> with more systemd, it will give even MORE shit
2015-09-01T02:33:02 < kakimir> you hate lunix so muxh you learn it
2015-09-01T02:33:02 < dongs> kakimir: beacuse unlike you, I can fucking read English
2015-09-01T02:33:10 < dongs> and what zyp said is pretty clear
2015-09-01T02:33:26 < zyp> I heard systemd guys got so NIH about ntpd, so they made their own timesyncd
2015-09-01T02:33:37 < dongs> kakimir: no, until 5 minutes ago I had no idea that was possible
2015-09-01T02:33:42 < dongs> zyp: haha
2015-09-01T02:34:12 < dongs> wow, you werent joking
2015-09-01T02:34:48 < BrainDamage> they also made their own su
2015-09-01T02:35:00 < BrainDamage> which is getting all neckbeards on fire
2015-09-01T02:35:15 < dongs> is all this shit written in C++
2015-09-01T02:35:47 < kakimir> do you ever get that feeling you shouldn't go any deeper?
2015-09-01T02:36:05 < kakimir> you are talking pure lunix already
2015-09-01T02:39:41 < __rob> anyone know how to hide rooms or make them transparent in Altium ?

2015-09-01T02:49:03 < zyp> idk, I don't use rooms
2015-09-01T02:49:18 < zyp> I haven't really seen the point, so I just turn off room generation
2015-09-01T02:54:01 < dongs> __rob: l, show/hdie stuff, you can turn off rooms rendering
2015-09-01T02:54:23 < dongs> do you have a reason to use them?
2015-09-01T02:54:30 < dongs> or you just didnt turn them off in design
2015-09-01T02:56:03 < dongs> if you dont actually need them (no repeating designs, etc) just turn them off in schematic, c,o,class generation, turn off generate rooms checkbox, then turn off generate classes checkbox, and update to pcb.
2015-09-01T02:57:04 < zyp> yeah, that's what I do
2015-09-01T02:57:44 < dongs> i did use htem a few times when needed
2015-09-01T02:57:52 < dongs> like rows on that huge hallsensor board
2015-09-01T02:58:00 < dongs> or 2 LED drivers on ipad thing
2015-09-01T02:58:08 < dongs> made one schematic block, routed it, copied to 2nd one
2015-09-01T02:58:21 < dongs> but I dont see any use for them on a non-hierarchical schematic

2015-09-01T05:51:24 < Getty> out of some curiosity i had made my device show like a counter over an external clock and parallel a counter of internal clock, and out of distraction it is now still running a week, and both timers are still "sync"
2015-09-01T05:51:47 < Getty> i mean yeah logical, i am just fascinated by this fact right now..... i mean like billions and billions of devices with the exact same 1Hz....
2015-09-01T05:52:05 < Getty> or is it probably less fascinating if you understand how they do it "down under"?
2015-09-01T05:52:47 < dongs> wat
2015-09-01T05:53:29 < Getty> well i have 2 clocks and they are in perfect sync... i mean yeah if they say they give 1Hz then it is 1Hz or whatever xxxHz, i am just fascinated that like... they all do it right
2015-09-01T05:54:04 < dongs> 2 clocks on same chip or wat
2015-09-01T05:54:09 < Getty> no 2 chips
2015-09-01T05:54:24 < Getty> one is the arm itself, with his internal clock and one external clock
2015-09-01T05:54:40 < Getty> i mean it doesnt matter, its logical that it always works worldwide with all chips as else those chips can communicate with the other
2015-09-01T05:55:28 < Getty> i am just fascinated in this moment by the "black box" that they all have that its exactly "right" timed, exactly right frequence

2015-09-01T06:03:30 < Getty> well the external clock is on 4khz and i have an overflow that is then again making a counter that leads in the end to a +1 on a visual counter
2015-09-01T06:03:58 < Getty> the other one is... aehm i dont know, i think a 8 prescaler or so timer, which also ends up in +1 visual counter / second
2015-09-01T06:04:20 < zyp> so you're visually counting seconds?
2015-09-01T06:04:27 < Getty> yeah of course my "visual" "in sync" is not like really to be seen as perfect
2015-09-01T06:05:05 < Getty> but i just thought about it in a bigger scope, like that those 2 "random chips" are having the same Hz-counter "speed" they run to and all others are that too
2015-09-01T06:05:13 < Getty> and i feel like i wanna know how they can do that
2015-09-01T06:06:09 < Getty> is it like really that they "tune some values" till the testsuite said "Yep, thats a proper 1 Hz"?
2015-09-01T06:06:48 < zyp> timing is derived from the crystals, they are tuned to a given accuracy, typically 30ppm or so
2015-09-01T06:07:12 < Getty> so the arm includes those crystals, and they are again like mass produced and used by several?
2015-09-01T06:07:24 < zyp> 30ppm of a week is 18 seconds, so you can expect two independent clocks to not be more than 18 seconds out of sync after a week
2015-09-01T06:07:27 < Getty> somehow a bit magical "crystal" :-)
2015-09-01T06:07:31 < zyp> the crystals are external parts
2015-09-01T06:07:51 < Getty> yeah well "external", i mean, its inside the chip :)
2015-09-01T06:08:12 < Getty> or am i confused?
2015-09-01T06:08:24 < zyp> it's certainly not inside the chip
2015-09-01T06:08:58 < Getty> ah ok, i am not like making the boards, so its like there is always external crystal to give the pulse?
2015-09-01T06:09:28 < zyp> crystals usually have a metal top, or sit inside a metal canister, so they are usually easy to spot, on the board next to the microcontroller itself
2015-09-01T06:09:40 < zyp> the top is normally labelled with the frequency
2015-09-01T06:09:42 < Getty> ah yeah ok then i know which one it is here
2015-09-01T06:09:55 < Getty> yeah and the ARM board has it too, yeah
2015-09-01T06:10:04 < Getty> 18 seconds in a week is "big"
2015-09-01T06:10:12 < Getty> mine run here like 1 1/2 week now
2015-09-01T06:10:27 < zyp> yeah, but that's worst case, over the full temperature range
2015-09-01T06:10:34 < Getty> and its not 1ms desync, ok, lets say, maximum 10-50ms
2015-09-01T06:10:41 < Getty> ah ok, logical
2015-09-01T06:10:51 < zyp> if you have two parts sitting in the same stable temperature then less would not be surprising
2015-09-01T06:11:33 < Getty> oh wait, even more... i just see one crystal here, isnt the dc1307 (the external clock thing i use) also needing one?
2015-09-01T06:11:37 < Getty> so like both use the same crystal?
2015-09-01T06:11:44 < zyp> if you need more accurate timing, you get temperature compensated crystals as well (tcxo)
2015-09-01T06:12:17 < Getty> cause if they use the same crystal then it might be even more logical why its never not in sync ;)
2015-09-01T06:12:19 < zyp> which has a small heater built in which keeps the crystal at a stable temperature even if the environment is changing
2015-09-01T06:13:15 < zyp> idk
2015-09-01T06:13:32 < zyp> some external rtc chips have the crystal built into the chip itself

2015-09-01T06:28:43 < upgrdman> anyone know of an engineering notebook (graph paper on one side, lined paper on the other side) that is spiral bound on the TOP edge (not the side) ?
2015-09-01T06:32:01 < dongs> .. paper?
2015-09-01T06:32:09 < dongs> when was the last time you wrwote soemthing on paper that wasnt your signature
2015-09-01T06:32:13 < Rickta59> http://www.amazon.com/Tops-Docket-Spiral-Quadrille-63825/dp/B001DYZ3T0
2015-09-01T06:32:37 < upgrdman> dongs, all the time. little diagrams, notes, etc.
2015-09-01T06:32:56 < Rickta59> http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Doffice-products&field-keywords=spiral+steno+pad
2015-09-01T06:33:47 < englishman> i wrote a note to fedex to drop the pkg instead of making me go drive 25km to pick shit up. but i could have easily printed it out too
2015-09-01T06:34:12 < upgrdman> Rickta59, those look like either graph or lined, but not both
2015-09-01T06:34:25 < upgrdman> i like paper that is graph on one side, and lined on the other side
2015-09-01T06:34:44 < Rickta59> sounds like you need a printer and some hole punches and some wire
2015-09-01T06:34:59 < Rickta59> or you could take it apart and buy both types and then rewire them
2015-09-01T06:36:44 < upgrdman> i've found (and use) some that are graph/line combos, but theyre not spiral bound, which i find annoying
2015-09-01T06:37:01 < upgrdman> since they wont lay flat and you cant store your pen in the sprial
2015-09-01T06:38:01 < upgrdman> i want something like this, but with the spiral on the top edge:  http://www.amazon.com/NATIONAL-Engineering-Science-Notebook-33610/dp/B001E69X52/ref=sr_1_8?s=office-products&ie=UTF8&qid=1441078661&sr=1-8&keywords=engineering+paper
2015-09-01T06:50:15 < upgrdman> i like the stuff from mg chemicals
2015-09-01T06:50:43 < upgrdman> but i used leaded. not sure about whats a good lead free solder.
2015-09-01T06:51:23 < englishman> the 1/8" stuff from the plumbing store works well

2015-09-01T07:59:54 < Bright> how do i select a device?
2015-09-01T08:09:37 < zyp> for what?
2015-09-01T08:10:06 < Bright> uh my application
2015-09-01T08:10:14 < Bright> i think i got itthough
2015-09-01T08:10:18 < zyp> sure, but what are you doing?
2015-09-01T08:10:56 < zyp> if you tell me what you want to do, I can tell you what part I'd pick for the job and the rationale for it
2015-09-01T08:12:08 < Bright> remote control TENS
2015-09-01T08:12:21 < zyp> TENS?
2015-09-01T08:12:39 < Bright> transcutaneous electrical nerve stimulation
2015-09-01T08:12:58 < zyp> oh
2015-09-01T08:13:21 < Bright> i just need an MCU to plug into the computer and be able to put TENS parameters into the device from i
2015-09-01T08:13:36 < Bright> like
2015-09-01T08:14:11 < Bright> emulate a serial port or whatever
2015-09-01T08:14:15 < zyp> so, usb?
2015-09-01T08:14:21 < Bright> yea
2015-09-01T08:14:47 < zyp> if you don't have any other requirements and just want the cheapest part with usb, you want f072 or f042
2015-09-01T08:15:32 < Bright> that looks like it works
2015-09-01T08:15:39 < Bright> it doesn't need a lot of brains

2015-09-01T08:17:01 < zyp> well, any of the usb capable parts would work, but when it's not a matter of what other features you need, it becomes a matter of what other features you don't want to pay for
2015-09-01T08:33:18 < jpa-> next question will be: "what usb library will use" :)

2015-09-01T09:23:33 < dongs> isnt that tarduino shit
2015-09-01T09:26:23 < dongs> heh
2015-09-01T09:26:29 < dongs> with 2 i2c preipherals
2015-09-01T09:26:32 < dongs> theoretically
2015-09-01T09:26:38 < dongs> can i start i2c read at exacly same time?
2015-09-01T09:26:45 < dongs> from 2 differnt places.
2015-09-01T09:27:06 < zyp> uh
2015-09-01T09:27:11 < zyp> exactly?
2015-09-01T09:27:14 < dongs> yep.
2015-09-01T09:27:20 < dongs> ~exactly~
2015-09-01T09:27:21 < zyp> sounds dumb
2015-09-01T09:27:25 < dongs> it is
2015-09-01T09:27:27 < zyp> is this about adc sampling?
2015-09-01T09:27:30 < dongs> not even
2015-09-01T09:27:34 < dongs> just reading a register
2015-09-01T09:27:39 < dongs> that probably doesnt even update that fast
2015-09-01T09:28:11 < zyp> idk, what precision do you need on «exactly»?
2015-09-01T09:28:39 < dongs> i think doing i2C1->CR |= EN; I2C2->CR |= EN; is not exact enough
2015-09-01T09:28:53 < dongs> (or wahtever fires off read)
2015-09-01T09:29:15 < zyp> that's why I ask
2015-09-01T09:29:45 < zyp> just scheduling them like that probably gets them within a few microseconds of each other
2015-09-01T09:29:56 < zyp> in other words, a few bit times on the i2c buses
2015-09-01T09:30:03 < dongs> yeah
2015-09-01T09:31:43 < jpa-> dongs: you can use extra gpio + fets to clock strecth them both buses

2015-09-01T09:32:31 < dongs> and then release it right after firing off i2c read?
2015-09-01T09:32:50 < jpa-> maybe best to do it before the part that needs to be accurate
2015-09-01T09:33:54 < jpa-> with the idle state being high, you may have to wait for the first falling clock of the i2c read, and then pull sck down
2015-09-01T09:34:22 < jpa-> or you could just use software i2c and bitbang it on the same port

2015-09-01T10:26:45 < dongs> So, because a company was not able to successfully predict development times prior to beginning development Your going to call it a scam 3 months after the initial estimation of due date... There are many things on kick starter which are significantly more delayed and it (to the best of my knowledge) is a risk you accept by backing a project on kick starter.

2015-09-01T12:14:48 < Roklobsta> I am trying to google it.  At old employer 10 years ago we tried PCBs with no via used a technique of pads and hills/bumps pushed against each other at layer boundaries
2015-09-01T12:15:18 < zyp> I once made a two layer mixed smt/pth design with no other vias than the pth pins
2015-09-01T12:15:31 < zyp> in high school
2015-09-01T12:15:38 < Roklobsta> this wa 8 layers
2015-09-01T12:15:48 < Roklobsta> it was weird to see a board with BGA pads and no holes
2015-09-01T12:15:50 < zyp> because it was etched at school and I couldn't be assed to do vias by hand
2015-09-01T12:17:53 < Roklobsta> the via profiles look like this.  you can see the pyramid bumps get pushed against a pad.  https://www.google.com.au/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0CAcQjRxqFQoTCNfy6qLA1ccCFWZgpgodYCsORw&url=http%3A%2F%2Fwww.uyemura.com%2Fnew-developments-in-DC-acid-copper-for-vertical-plating-tanks.htm&ei=H23lVZfnMebAmQXg1ri4BA&psig=AFQjCNExVtMeEZ2XguMuUWobAQFqjfj1FA&ust=1441185416

2015-09-01T13:36:23 < dongs> I see in the 2.9 beta that the Wine compatibility issues do not appear to have been addressed. The "Title and Sheet Setup" dialog can still cause the program to hang and other dialog controls (such as the library filter dialog dropdowns) don't properly process mouse input all of the time.
2015-09-01T13:36:28 < dongs> Is there any intent to address these issues in this next major release?

2015-09-01T13:37:08 < dongs> s a request I would like for NOVRAM to start looking long termatn this matter. That is writing code so that Dip Trace runs native on a LINUX OS. I say this because as Windows 10 has recently been released the invasive nature of this OS has become readily apparent. I was predisposed to dropping Windows when I loaded Windows 7 five years ago. Seeing this unwelcome development reaffirmed my decision. Come 2020 when Microsoft's support for Windows 7 ends I'm done with Wi

2015-09-01T14:18:04 < Lux> any ideas if an exti interrupt will still fire if the pin is set to AF ?
2015-09-01T14:19:07 < zyp> probably
2015-09-01T14:20:13 < zyp> I'd expect it to fire as long as the digital input block is enabled, i.e. in all except analog mode
2015-09-01T14:20:33 < Lux> that's what i tought, thanks

2015-09-01T14:32:52 < dongs> For instance, all outdoor mode and indoor modes might be spot on but swarming isn't included yet. If you want swarming and choose to wait until that is completed, tested and released, the delay could be months.

2015-09-01T14:54:24 < dongs> whatcha hackig on
2015-09-01T14:54:28 < zyp> thanks for letting me know
2015-09-01T14:54:28 < dongs> your super pro fc?
2015-09-01T14:54:41 < zyp> I like being right
2015-09-01T14:54:47 < Lux> making an esc
2015-09-01T14:54:51 < dongs> ah
2015-09-01T14:54:52 < dongs> right
2015-09-01T14:54:57 < dongs> zyp, what would be a usecase for this
2015-09-01T14:55:01 < Lux> and doing an spi slave with an f0
2015-09-01T14:55:13 < dongs> esc on F0 sounds kinda meh does it even have comparators
2015-09-01T14:55:17 < zyp> dongs, for what?
2015-09-01T14:55:22 < dongs> zyp, exti while in  AF
2015-09-01T14:55:30 < Lux> dongs: you can just use the adc
2015-09-01T14:55:38 < Lux> and do that instaspin stuff
2015-09-01T14:55:44 < dongs> lux, well yeah, ...
2015-09-01T14:55:45 < dongs> mkay
2015-09-01T14:55:51 < Lux> in theory it's better than zero crossing
2015-09-01T14:56:00 < dongs> ah, diferent algo? mkay
2015-09-01T14:56:08 < Lux> i also get pretty much the same efficiency as with stock escs
2015-09-01T14:56:24 < zyp> dongs, idk, curious myself actually
2015-09-01T14:57:05 < Lux> i'm using the interrupt on the cs/nss pin
2015-09-01T14:57:36 < Lux> and i think it also disables the spi when high, so i wanted it still as AF
2015-09-01T14:57:48 < zyp> ah, yeah, that makes sense
2015-09-01T14:58:00 < zyp> then you can reset your state machine when deasserted
2015-09-01T14:58:03 < dongs> I am excited for people to just see the physical Zano, packaging, carry cases, batteries, Zano fuels etc. It all looks so cool and is such lovely quality. We are very proud of it. Your quite right, if people don't want to use it, just leave it boxed until the software matures to a point they feel comfortable using it.
2015-09-01T14:58:16 < Lux> yeah, that was the plan
2015-09-01T14:58:25 < Laurenceb> what if zano triggers someone?
2015-09-01T14:58:34 < zyp> I remember I did SPI slave once, and I was annoyed that there were no built in support for interrupting on CS change
2015-09-01T14:58:37 < Laurenceb> do we have an agreed coping phrase?
2015-09-01T14:58:53 < zyp> I didn't think of EXTI, so I used a simple timeout for resetting
2015-09-01T14:59:02 < Lux> yeah, the hardware support for spi slave is kinda meh
2015-09-01T14:59:54 < Lux> it should support to align the data packets for the dma depending on the cs signal, without having to handle it in the interrupts

2015-09-01T15:01:52 < Laurenceb> well it said earth
2015-09-01T15:02:59 < dongs> You are quite right, I won't release the software even if it means delays until I am happy that each version is correct. I have a launch issue (I am not happy with launch at the moment) because of the new propellers and the extra lift. Don't get me wrong, it launches very nicely and smoothly but the altitude target is not being controlled properly. So I say launch to 1200mm it goes to 1500mm. In real terms most probably wouldn't notice but it drives me nuts until it 
2015-09-01T15:03:17 < Steffanx> in russialand they don't do different colours for neutral, phase, switch wire ?
2015-09-01T15:03:34 < Steffanx> all i see is red ( and green/white to the device )

2015-09-01T15:04:46 < dongs> the battery is held in place by a special very fine hook and loop (like velcro) system. It is light and robust and doesn't require any fiddling to fit a battery. It is also easy to change in the event of wear. All batteries come with three replacement pads so easy to change. After much thought and design, it was the best way we could find of supporting the various height batteries and making it easy to fit and replace the batteries as well.

2015-09-02T00:02:14 < kakimir> you need qt instead of tcl/tk?
2015-09-02T00:03:02 < kakimir> does hello world differ much at all btw?
2015-09-02T00:10:43 < Tectu> Qt? here.
2015-09-02T00:10:47 < Tectu> I love fucking Qt
2015-09-02T00:10:51 < Tectu> Qt is master race
2015-09-02T00:10:57 < Tectu> Qt is hitler of frameworks
2015-09-02T00:11:01 < upgrdman> trolling or genuinely like qt?
2015-09-02T00:11:07 < Tectu> genuinely
2015-09-02T00:11:11 < upgrdman> k
2015-09-02T00:11:18 < Tectu> I do/did many Qt project
2015-09-02T00:11:21 < Tectu> quite big ones too
2015-09-02T00:11:27 < bvernoux> it will be nice to generate little exe with Qt ;)
2015-09-02T00:11:28 < Tectu> uGFX-Studio is 100% Qt
2015-09-02T00:11:34 < Tectu> and the current one that will be way bigger is 100% Qt too
2015-09-02T00:11:46 < upgrdman> screenshots of said studio?
2015-09-02T00:11:50 < bvernoux> I doubt even using static link avoid needs of 20MB Exe for a simple Hello world
2015-09-02T00:12:26 < upgrdman> bvernoux, be a man and distribute your programs in the form of a fully contained live cd ;)
2015-09-02T00:12:43 < upgrdman> 700MB "exe" ftw
2015-09-02T00:13:00 < bvernoux> but anyway the concept of Qt is very nice
2015-09-02T00:13:13 < bvernoux> I'm starting to do some stuff with it ;)
2015-09-02T00:13:23 < kakimir> how much 1oz is in millimeters of copper?

2015-09-02T00:13:30 < kakimir> what is oz?
2015-09-02T00:13:46 < Tectu> upgrdman, check videos: https://www.youtube.com/user/MrTectu/videos
2015-09-02T00:14:13 < upgrdman> thx
2015-09-02T00:14:19 < upgrdman> screenshoot looks pretty sweet
2015-09-02T00:14:19 < Steffanx> Google knows kakimir
2015-09-02T00:14:31 < kakimir> ounce?
2015-09-02T00:14:48 < upgrdman> google "thickness of 1oz copper"
2015-09-02T00:15:02 < kakimir> ounces per square foot
2015-09-02T00:17:25 < Tectu> upgrdman, ugfx studio is just a spare time project. about 25k lines of code now
2015-09-02T00:17:39 < upgrdman> cool
2015-09-02T00:17:42 < upgrdman> neat tetris
2015-09-02T00:17:49 < upgrdman> i also did that on my f0 with lcd
2015-09-02T00:18:01 < Tectu> upgrdman, cool :)
2015-09-02T00:18:09 < Tectu> upgrdman, actually that tetris was written by Fleck
2015-09-02T00:18:22 < Tectu> upgrdman, it is part of the uGFX repository now as an official demo
2015-09-02T00:18:49 < Fleck> ?
2015-09-02T00:19:32 < upgrdman> nice
2015-09-02T00:19:44 < upgrdman> heres mine, a bit simpler: https://youtu.be/axYgyjWLWhE?t=512
2015-09-02T00:20:34 < Tectu> upgrdman, neat :)
2015-09-02T00:21:10 < Tectu> so I watched you playing tetris, now I am watching you putting a glas of water into the microwave
2015-09-02T00:21:26 < upgrdman> ya it has a spectrum analyzer build in
2015-09-02T00:21:41 < upgrdman> i showed the 2.4g leakage of microwave oven for fun
2015-09-02T00:21:49 < kakimir> I bet there is no way to fix impendance mismatch when coax impendance is 50ohms and trace is 110ohms?

2015-09-02T00:23:06 < Tectu> upgrdman, and this is uGFX on an F407. Note that it samples in real time etc. so uGFX does not get the full CPU time:  https://www.youtube.com/watch?v=73ygBq9Wq_M
2015-09-02T00:24:36 < Tectu> uh, this is uGFX on a fucking B/W nokia display on an STM32VL:   https://www.youtube.com/watch?v=Lfyb9C57rx8
2015-09-02T00:25:19 < kakimir> I see why they would put extra cost for under 1.2mm board.. 50ohm impendance line width reduces dramatically
2015-09-02T00:25:20 < Tectu> upgrdman, I actually was searching for this one: That too is uGFX on STM32F407 with real ADC samples being processed:  https://www.youtube.com/watch?v=WmpKC9ODH8c

2015-09-02T00:31:41 < Tectu> bvernoux, uGFX is working on the STM32F7 discovery board including hardware acceleration
2015-09-02T00:31:48 < bvernoux> Tectu, no but I know some guys which could be interested
2015-09-02T00:32:01 < Tectu> bvernoux, can we get back to this next week?
2015-09-02T00:32:13 < Tectu> bvernoux, thanks for the offering. I am definitely interested.
2015-09-02T00:32:17 < bvernoux> yes
2015-09-02T00:32:29 < Tectu> thank you, very appreciated
2015-09-02T00:32:36 < bvernoux> I have already a STM32F7 Disco to test even if the LCD is a bit broken on border
2015-09-02T00:32:54 < Taxman> i am attending an st F7 workshop mit september in munich
2015-09-02T00:33:01 < Taxman> probably this is the same
2015-09-02T00:33:09 < bvernoux> mine is 22Sept in Grenoble
2015-09-02T00:33:17 < bvernoux> near the factory which build the MCU ;)
2015-09-02T00:33:42 < kakimir> what is in munich?
2015-09-02T00:33:49 < Tectu> Taxman, I plan to be there as well
2015-09-02T00:33:56 < Taxman> and i have written the F7/F4 DMA2D acceleration code for ugfx :)
2015-09-02T00:34:25 < Taxman> Tectu: Good idea
2015-09-02T00:34:29 < bvernoux> STm32F7 Disco screen is very nice too
2015-09-02T00:34:32 < bvernoux> or a cheap board
2015-09-02T00:34:56 < Tectu> the board is cool for demos, sadly totally sucks as a dev board
2015-09-02T00:35:05 < Tectu> but the screen and touch is definitely very good for that price point
2015-09-02T00:35:12 < Tectu> haven´t added the audio driver to uGFX yet :/
2015-09-02T00:35:20 < bvernoux> yes for dev board it miss lot of things
2015-09-02T00:35:33 < bvernoux> except to do some Gfx stuff
2015-09-02T00:36:00 < bvernoux> problem is the available GPIO are just for Arduino so very limited
2015-09-02T00:36:00 < Taxman> i assume it was a master thesis work
2015-09-02T00:36:01 < PeterM> Woo! experiencing the true speed of australias super fast national broadband network, a earthshatteringly fast 25mbit down/5mbit up!
2015-09-02T00:36:12 < Fleck> lol
2015-09-02T00:36:18 < Tectu> uGFX now does keyboard stuff to (both external physical ones and onscreen virtual ones). I should do a demo with that, bvernoux
2015-09-02T00:36:38 < bvernoux> Tectu, ha yes great
2015-09-02T00:36:39 < Tectu> PeterM, I got 10M/1M
2015-09-02T00:36:47 < Tectu> PeterM, and Fleck got some 200M/100M or something
2015-09-02T00:36:55 < Fleck> 200/200
2015-09-02T00:37:00 < Tectu> -___-

2015-09-02T00:37:29 < bvernoux> Tectu, they are very interested by micropython too
2015-09-02T00:37:32 < Taxman> i pay 30 EUR per month for 50/10
2015-09-02T00:37:49 < bvernoux> Tectu, it will be nice to have uGFX shell with micropython running in it ;)
2015-09-02T00:38:05 < PeterM> Tectu, i pay $80 AU (50~EUR) for 25/5
2015-09-02T00:38:48 < Tectu> bvernoux, we already have a console widget :)   (although a crude one, to be honest)

2015-09-02T00:39:10 < Tectu> bvernoux, we definitely should get to that.
2015-09-02T00:39:21 < bvernoux> Tectu, a crude one is good if there is just enough to do a basic terminal stuff (with scroll bar if possible)
2015-09-02T00:39:35 < bvernoux> but anyway the most interesting is a demo with some nice graphic ...
2015-09-02T00:39:42 < Tectu> bvernoux, sadly I am very busy this week. Are you available next week?
2015-09-02T00:40:14 < bvernoux> as they will show => 4:00 PM – 5:00 PM

2015-09-02T00:40:33 < bvernoux> and it could be great to see there is alternative to their Graphics stuff by using uGFX
2015-09-02T00:40:51 < Tectu> indeed. We have many customers that switch from (ST)emWin to uGFX
2015-09-02T00:41:02 < Tectu> (many compared to how little uGFX is, no PR and crap)
2015-09-02T00:41:16 < Tectu> see guys, this is what you pay 80 EUR / month for:  http://www.speedtest.net/my-result/4629035031
2015-09-02T00:41:33 < Taxman> bvernoux: STemWin demonstration?
2015-09-02T00:41:42 < bvernoux> yes STemWin IIRC
2015-09-02T00:41:59 < bvernoux> last year it was something like that on STM32F4 Disco
2015-09-02T00:42:18 < bvernoux> and also Java stuff with GFX (slow ....)
2015-09-02T00:42:31 < bvernoux> but IIRC they have abandonned embedded Java ;)

All tuneable but it has occurred due to a series of small changes I have made, I just need to retune that part of the system. Only take an hour or so once I am done with GPS aspects.

2015-09-02T06:58:57 < dongs> still downloading, slow as ballz
2015-09-02T07:00:19 < dongs> yep
2015-09-02T07:00:21 < dongs> thats the RM
2015-09-02T07:01:42 < dongs> DMA mapping is same as F103
2015-09-02T07:02:52 < dongs> but do you think they have sa me bugs in  I2C peripheral????????????????????????????????????????
2015-09-02T07:06:10 < dongs> it has Unique ID at same place.
2015-09-02T07:06:14 < dongs> 0x1FFFF7E8
2015-09-02T07:06:36 < jpa-> cloning i2c bugs would be fun :)
2015-09-02T07:06:51 < jpa-> i wonder if they actually did anything to it, or if it is just silicon copy
2015-09-02T07:07:01 < dongs> check the differences.
2015-09-02T07:07:03 < dongs> its faster flash
2015-09-02T07:07:07 < dongs> plus some ot her stuff
2015-09-02T07:07:21 < dongs> i need to dicknplace i cant look at this shit now :()
2015-09-02T07:07:34 < jpa-> so stolen vhdl/verilog probably.. interesting
2015-09-02T07:08:10 < dongs> or they bought same peripherals that ST did.. but who knows
2015-09-02T07:08:49 < Rickta59> you would think if it was stolen ST would have responded by now no?
2015-09-02T07:09:00 < Rickta59> it has been out there for a couple of years with announcements
2015-09-02T07:09:10 < dongs> they're a licensee of arm stuff
2015-09-02T07:09:50 < jpa-> i wouldn't have been surprised if there was an official second-source for STM32 parts, but that doesn't look like one :P
2015-09-02T07:10:36 < Rickta59> gflash is supposedly theirs

2015-09-02T10:51:19 < dongs> heh. free toshiba TV hdd thing arrived. it connects to TV by 3 USB connectors. 2x 3.0 1x 2.0. Inside looks like 3 HDDs - 2x 2TB and 1x 500GB. 4TB part is used to record all the channels 24/7 so you can timeshift to anything anytime. 500gb part is for general random recordings / scheduled recording shit. fucking nuts, who watches this much TV
2015-09-02T10:53:00 < Roklobsta> er, i have 2TB set up for recording DVB-T.
2015-09-02T10:53:36 < Roklobsta> not quite as sophisticated as your new toy.
2015-09-02T10:54:22 < Roklobsta> I hope that thing can do RAID
2015-09-02T10:54:26 < dongs> i can now see why it cost liek $400 to buy, but I'd never pay for it. glad it was free, I'll probably turn off the 24/7 recording thing on it after a couple days
2015-09-02T10:54:43 < dongs> i dont even watch TV enough to care

2015-09-02T11:37:31 < dongs> Jorge, I don't mind them being late, what I do mind is the way they initially showed the drone to work- on an iPhone, with all the features they used in the promo video to collect all the support funds to begin with. They also have not shown one video proving the flight time outdoors or the height it can reach or the stability outdoors etc. To me that is very suspicious as they over promised and so far have under delivered. Poor communication, not being transparent a

2015-09-02T12:37:23 < dongs> stm32 is 1.8V
2015-09-02T12:37:27 < dongs> so probaly 60nm process
2015-09-02T12:37:37 < dongs> so not just copy from stm32

2015-09-02T12:45:21 < dongs> so probly next week
2015-09-02T12:46:25 < dongs> karlp: i wonder if that would be a good way to detect gd32 programmatically
2015-09-02T12:46:30 < dongs> try to poke a 1 into that register
2015-09-02T12:46:32 < dongs> and read it back
2015-09-02T12:46:35 < dongs> if its zero, then its probly stm32
2015-09-02T12:47:02 < Steffanx> maybe the chip id is totally different
2015-09-02T12:47:08 < dongs> sure
2015-09-02T12:47:27 < dongs> unless there's obvious fixed parts in it tho, i wouldthn rely on that
2015-09-02T12:47:50 < dongs> even then ST ID could eventually collide with that
2015-09-02T12:48:17 < artag> is it a total clone, as in no ARM license ?
2015-09-02T12:48:17 < Steffanx> oh no, it seems to be the same
2015-09-02T12:48:18 < Steffanx> http://www.newlifex.com/showtopic-1234.aspx
2015-09-02T12:48:28 < dongs> artag: they are an arm licensee
2015-09-02T12:48:29 < Steffanx> oh no that's a lie
2015-09-02T12:48:41 < artag> so a licensed chip that copies the STM perpherals ?
2015-09-02T12:48:45 < dongs> .. yes
2015-09-02T12:48:49 < dongs> apparently..
2015-09-02T12:48:49 < dongs> haha
2015-09-02T12:49:17 < artag> I'd have thought if STM objected they'd withdraw the ARM license
2015-09-02T12:49:20 < dongs> CPUID:0x412FC231 ARM ARMv7-M Cortex-M3 R1p2
2015-09-02T12:49:21 < dongs> errr
2015-09-02T12:49:30 < dongs> they're using newer rev/patch of the cortex m core
2015-09-02T12:49:37 < dongs> stm stuff is r0/p0 or somethign
2015-09-02T12:49:53 < Steffanx> are you sure, the read out of the stm32f103 shows the same
2015-09-02T12:50:00 < dongs> r1p2?
2015-09-02T12:50:15 < Steffanx> i should sleep more
2015-09-02T12:50:17 < dongs> that chinaforum says R1P1 for stm32
2015-09-02T12:50:20 < Steffanx> it does not show the same :P
2015-09-02T12:50:45 < dongs> chip IDs look like ascii garbage
2015-09-02T12:51:46 < karlp> the chip id should hopefully be constant, there's also the unique id reg that should hopefully change.
2015-09-02T12:51:58 < dongs> er unique id i what i meant
2015-09-02T12:52:17 < dongs> that china printout calls it that

2015-09-02T12:53:14 < jpa-> IIRC unique id is ascii crap in also stm32
2015-09-02T12:53:15 < karlp> whatpage 593,
2015-09-02T12:53:37 < karlp> that' the one that has the "this is a f103, or l4, or f042" shit
2015-09-02T12:53:46 < karlp> what's the gd32 really have there?

2015-09-02T12:55:00 < dongs> rite
2015-09-02T12:57:18 < Steffanx> There even is some document about how compatible this gd32 is with stm32
2015-09-02T12:57:58 < Steffanx> lol they totally failed at low power

2015-09-02T12:58:25 < Fleck> ouch
2015-09-02T12:58:51 < jpa-> i wonder if that is due to the process differences
2015-09-02T12:59:00 < karlp> yeah, looked like power was pretty high :)
2015-09-02T12:59:08 < jpa-> extra powerful processor
2015-09-02T12:59:10 < karlp> it's usb otg too, not just usb fs like f103
2015-09-02T12:59:23 < Steffanx> while standby is closer: GD32F: 10.5uA vs STM32F10X: 3.4uA
2015-09-02T12:59:34 < karlp> still  triple :)

2015-09-02T14:39:01 < jadew> don't know, I bet the chinese do a lot of stuff for hobby use only
2015-09-02T14:39:25 < jadew> they surely have a lot of technology in place to come up with new things that are only appealing to the hobbyists
2015-09-02T14:41:12 < jadew> I bet they sold more as OLED modules than embeded in that player
2015-09-02T14:41:34 < jadew> the customers for the player buy 1
2015-09-02T14:41:45 < jadew> I buy in 10s
2015-09-02T14:43:01 < Steffanx> they also do spi Laurenceb

2015-09-02T17:15:47 < karlp> the demo sw I tried had yellow on top too, but I didn't read any datasheets myself, sif
2015-09-02T17:16:28 < Laurenceb> ok
2015-09-02T17:17:24 < karlp> the same vendor sells "nice" colours too, but the yellow/blue one is just much cheaper

2015-09-02T17:25:55 < kakimir> yes
2015-09-02T17:26:01 < jpa-> could also be just a matter of some less common type/freq/case so that volumes are smaller
2015-09-02T17:28:09 < kakimir> same size
2015-09-02T17:28:27 < kakimir> and datasheets seem to suck
2015-09-02T17:28:37 < jpa-> do you expect us to play guessing game?
2015-09-02T17:29:25 < kakimir> hmm could 12pf -> 8pf load capasitance make that much difference?
2015-09-02T17:29:56 < kakimir> okay and serries resistance is halved
2015-09-02T17:30:44 < jpa-> could just be a less common combination
2015-09-02T17:33:59 < kakimir> ended up with epson fa-128 series

2015-09-02T22:16:13 < kakimir> time to change
2015-09-02T22:16:36 < Steffanx> but how will you change it?
2015-09-02T22:18:02 < kakimir> 1) watch youtube tutorial
2015-09-02T22:18:13 < kakimir> 2) if in doubt call a friend
2015-09-02T22:18:23 < kakimir> 3)mess
2015-09-02T22:18:28 < Steffanx> 4) Garage
2015-09-02T22:18:39 < gxti> pay extra because you messed it up

2015-09-02T22:19:11 < zyp> PaulFertser, empty it out, fill it back up, bleed off air?
2015-09-02T22:19:15 < kakimir> some change every 100k
2015-09-02T22:19:29 < PaulFertser> zyp: there're different ways to bleed off air.
2015-09-02T22:19:34 < englishman> chaging brake fluid, without pro tools need 2 people, just pump fluid thru manually til its nice and clean
2015-09-02T22:19:47 < PaulFertser> zyp: one way involves an additional hose and some jar or such.
2015-09-02T22:19:50 < PaulFertser> Another doesn't.
2015-09-02T22:19:54 < zyp> PaulFertser, different? there is a pretty well defined order
2015-09-02T22:20:02 < englishman> whats the other way
2015-09-02T22:20:05 < zyp> and yeah, you use a hose and a jar to collect
2015-09-02T22:20:12 < englishman> you need a hose going up from the bleeder to make sure air doesnt get in
2015-09-02T22:20:21 < englishman> preferably clear so you can see the fluid and air inside
2015-09-02T22:20:23 < kakimir> ok
2015-09-02T22:20:34 < kakimir> you just run it thru slowly?
2015-09-02T22:20:50 < englishman> yea using the brake pedal as a pump
2015-09-02T22:21:17 < englishman> when the pedal hits the floor close the bleeder and get your assistant to pump slowly to make pressure again
2015-09-02T22:21:31 < PaulFertser> I always did it like that, and I've never seen anybody using the official way: you just "pump" the pedal several times and then hold it firmly, then another persons unscrews the bleeder a bit and observes the fluid fountain and screws it back when it's just about to end. Repeat until no air in the fountain is noticeable.
2015-09-02T22:21:55 < zyp> haha, that sounds dumb
2015-09-02T22:21:58 < englishman> wat
2015-09-02T22:22:02 < PaulFertser> Actually, works just fine.
2015-09-02T22:22:03 < englishman> if the fountain stops, theres no fluid left
2015-09-02T22:22:12 < englishman> and youre pumping a master cylinder dry
2015-09-02T22:22:14 < PaulFertser> You screw it back before it stops.
2015-09-02T22:22:27 < PaulFertser> The pressure drops gradually.
2015-09-02T22:22:29 < englishman> oh i read wrong
2015-09-02T22:22:41 < zyp> PaulFertser, sure it works, just way harder to judge
2015-09-02T22:22:56 < englishman> the clear hose is just to make sure no air gets back in, its easier to see bubbles and catch the fluid so it doesnt get all over your cv boots etc
2015-09-02T22:22:57 < PaulFertser> zyp: but less tools to use.
2015-09-02T22:23:10 < zyp> PaulFertser, because you can't afford a piece of clear plastic hose?
2015-09-02T22:23:23 < PaulFertser> Just because you do not have it handy.
2015-09-02T22:23:39 < PaulFertser> And there's little reason to complicate the procedure when it works fine without.
2015-09-02T22:23:40 < zyp> then you're just badly prepared
2015-09-02T22:24:05 < PaulFertser> Sometimes you have no choice.
2015-09-02T22:24:51 < zyp> yeah, I hate being forced to bleed off air from my brakes without being allowed to pick up a piece of clear hose first
2015-09-02T22:24:53  * PaulFertser doesn't like cars :/

2015-09-03T05:42:16 < upgrdman> not sure about everything, but i know for us, ul cert isn't so much a legal requirement but a "no one will buy it if you don't"

2015-09-03T05:45:50 < upgrdman> i imageine it's more like "insurance company will not insure us, unless xyz are UL cert'd"

2015-09-03T05:58:01 < upgrdman> random question: LDO drop-out voltages... so it's mostly because of the pmos, right? <50mOhm RdsON is easy to get, so why is drop out so noteworthy? is it becasue the high speed pmos's have high RdsON?

2015-09-03T08:21:03 < upgrdman> adc question. so the adc in an stm32, running at 1MSPS, gets really noisey if it's reading something with an impedance of just a few hundred ohms. incrasing the sampling duration fixes it. how do super fast adc's handle this? is their sampling cap much smaller, or do they need to be fed from a beefy analog buffer?
2015-09-03T08:22:39 < emeb_mac> both
2015-09-03T08:23:07 < emeb_mac> there are special low impedance buffer amps designed to drive the inputs of high-speed ADCs.
2015-09-03T08:23:28 < upgrdman> any reason why it's not done on one die?
2015-09-03T08:23:40 < upgrdman> e.g. adc + anal buffer in one chip
2015-09-03T08:23:48 < emeb_mac> some do.
2015-09-03T08:24:17 < emeb_mac> but often the silicon processes used for the ADC are different from those needed for the buffer amp.

2015-09-04T00:33:11 < Lux> has anyone here tried to do spi with crc on an stm32 ?
2015-09-04T00:33:54 < Laurenceb__> Lux: yes
2015-09-04T00:34:00 < Laurenceb__> but I forgot how it worked lulz
2015-09-04T00:34:02 < Laurenceb__> sorry
2015-09-04T00:34:03 < Lux> from what i understand from the ref manual it should all happen automatically when configured with dma, but i somehow get seemingly random values for the crc on the receive side
2015-09-04T00:34:13 < Laurenceb__> hmm
2015-09-04T00:34:18 < Laurenceb__> sounds like its working then
2015-09-04T00:34:23 < Lux> the stuff my slave sends back is constant, but not the crc
2015-09-04T00:34:26 < Laurenceb__> CRC should be seemingly random
2015-09-04T00:34:28 < Laurenceb__> oh
2015-09-04T00:34:29 < Lux> not really :)
2015-09-04T00:34:36 < Laurenceb__> paybe it needs the CRC resetting
2015-09-04T00:34:43 < Laurenceb__> thats usual for CRC hardware
2015-09-04T00:35:34 < Lux> could be, but from my undertanding it should be done by hardware
2015-09-04T00:35:46 < Lux> at least that's what the ref manual claims
2015-09-04T00:36:04 < Lux> too bad there are hardly any code examples using it :/

2015-09-04T05:17:43 < upgrdman> so, uh, timers. counting up and triggering at the end seems logical. why might you want a count-down timer?
2015-09-04T05:23:13 < upgrdman> err i have that backwards i think
2015-09-04T05:25:03 < upgrdman> like if you want a timer event after 30 "clock ticks" then it seems logical to have the counter start at 30 and count down to 0. but some people setup a counter up from (max_value - 30) until overflow. why?
2015-09-04T05:27:04 < dongs> The question is: can I record Full-HD 30 fps video with 1.0 software, and download them on my PC ?? (only if I connect Zano to PC via USB ? who cares! I do the same with my Gopro)  ;)

2015-09-04T05:35:16 < dongs> Obviously the jump in quality of video from v1.0 to v1.1 will be huge. In v1.1 the videos are still sent to your handset in preview frame rate and your handset records them. Lets say you get 10FPS from Zano whilst recording and Zano is running at 25FPS internally. The 15FPS that is not sent to your handset will be recorded and then from the app when you are happy with the preview after reviewing it, Zano can send the remaining 15FPS directly to your handset. The app

2015-09-04T05:50:31 < upgrdman> for center-aligned pwm?
2015-09-04T05:55:03 < upgrdman> when is center-aligned pwm used over normal pwm?
2015-09-04T05:57:08 < upgrdman> so center-aligned is only nice when you want to trigger something (like an ADC sampling) in the middle of a pwm cycle?
2015-09-04T06:07:22 < upgrdman> sure, why not

2015-09-04T11:36:18 < jpa-> Taxman: yeah, still
2015-09-04T11:36:34 < jpa-> now we finally noticed that half of them are not just corrupted but permanently damaged
2015-09-04T11:37:12 < jpa-> also noticed that cutting the power in middle of write causes corruption all over the flash, not just on affected pages; but there aren't enough blackouts to explain the incidence of the problems
2015-09-04T11:38:56 < Taxman> hmm
2015-09-04T11:39:11 < Taxman> how many write cycles did they have?
2015-09-04T11:41:08 < jpa-> i do not know, but should be in the few thousands
2015-09-04T11:41:29 < Taxman> a few thousands for flash? this is too much
2015-09-04T11:41:32 < jpa-> with 100000 specified and they break at around 2 million in our tests
2015-09-04T11:42:16 < Taxman> yes
2015-09-04T11:42:42 < jpa-> also the permanent damage occurs all over the flash, while the FAT table (yes, this thing runs FAT on non-wear-levelled flash) should receive a lot more writes
2015-09-04T11:42:58 < jpa-> so seems more like damage to the internal voltage pump or similar common circuits
2015-09-04T11:43:05 < Taxman> 100000 means 100000 but not together with the specified storage time

2015-09-04T11:43:45 < jpa-> do you know what is the part of flash that wears out?
2015-09-04T11:44:22 < Taxman> usually the damaged SiO2 where the breakthrough occurs
2015-09-04T11:44:57 < jpa-> so should be localized to specific bits?
2015-09-04T11:45:53 < Taxman> yes, bits that lose soon their programmed state and start to toggle

2015-09-04T13:42:49 < jpa-> well, situation is more like there are 100 000 of these devices on the field and they are failing now, 5 years after manufacture :)
2015-09-04T13:43:04 < jpa-> it may come to switching the flash chip for another spi flash
2015-09-04T13:43:57 < Taxman> what is your goal? Assessing how many will fail, too? or a software workaround to minimize trouble?
2015-09-04T13:52:53 < jpa-> well, my first goal is to explain to customer how it is not our fault, of course
2015-09-04T13:53:10 < jpa-> after that if a simple to make software or hardware modification is possible, that would be cool
2015-09-04T13:53:34 < jpa-> if such mod is not possible, it's just "tough luck" and the lawyers will work out who pays and what
2015-09-04T13:54:24 < jpa-> but currently our best theory is just that "these are crappy chips" and no way to prove it
2015-09-04T13:55:46 < BrainDamage> did the devices have unexpired warranty period?
2015-09-04T13:55:53 < Taxman> how long does it need to bring one to fail in laboratory?
2015-09-04T13:57:26 < jpa-> Taxman: so far haven't managed.. failure rate is 1-2% so far on the field and they have been there for 5 years
2015-09-04T13:57:43 < jpa-> BrainDamage: no, not really; but if it is a design fault or software fault, we may have some responsibility
2015-09-04T13:58:00 < jpa-> BrainDamage: if it is the flash manufacturer's fault, probably not our problem
2015-09-04T13:58:57 < jpa-> (our client is the manufacturer of the devices, we are just a design house)
2015-09-04T14:00:17 < Taxman> this is a disgusting problem
2015-09-04T14:01:43 < trepidacious> jpa-: NOR flash is normally pretty reliable, we use spansion nor flash or something similar and we've not had any problems (touch wood)
2015-09-04T14:03:29 < trepidacious> jpa-: Mind you I think we're only just coming up for 5 years ;(

2015-09-04T21:55:37 < yan_> i'm just wondering what the best way to organize data is.. don't want to import a full fs implementation, even as simple as fat12, just to store events of sensor data
2015-09-04T21:55:41 < yan_> and config settings
2015-09-04T21:57:15 < zyp> eh, if it's fixed on the board, there's no point in conforming to something that can be read on a different system either
2015-09-04T21:57:37 < jpa-> yeah
2015-09-04T21:57:52 < jpa-> especially if you can use custom protocol to read instead of usb msc or similar
2015-09-04T21:57:56 < zyp> so just do whatever fits your application and the memory write pattern

2015-09-05T00:56:23 < upgrdman_> in case it isn't obvious, queue.size() changes as you empty the queue, so the loop would end prematurely.

2015-09-05T03:04:16 < hjf> i have a problem with a STM32F405 board. at 3.3V it doesn't seem to work (some blinker program, CPU runs at 168MHz)
2015-09-05T03:04:29 < hjf> but at 3.2V... it works
2015-09-05T03:04:52 < kakimir> Sync_: where exactly?
2015-09-05T03:05:18 < hjf> i noticed this because it has a LM2596 regulator for 5V and a AMS1117 for 3.3V
2015-09-05T03:05:30 < hjf> when the program doesn't run (3.3V) it draws about 42mA
2015-09-05T03:05:38 < hjf> when the program runs (3.2V), it draws about 150mA

2015-09-05T03:27:20 < kakimir> interesting how mobilephones require a pile of activelly voltage controlled regulators
2015-09-05T03:27:59 < kakimir> for radios
2015-09-05T03:28:58 < kakimir> I wonder if those mobile phone parts would be utilized in other uses
2015-09-05T03:30:20 < kakimir> as everything made for mobile phones is made in millions of units
2015-09-05T03:31:02 < upgrdman> hjf, weird. anything else powered by the 3v3 rail?
2015-09-05T03:33:50 < Sync_> unlikely kakimir
2015-09-05T03:34:03 < Sync_> as they are so highly integrated
2015-09-05T03:35:05 < kakimir> what they need 4channel active ldos for in radios?
2015-09-05T03:35:20 < ds2> what's an active LDO?
2015-09-05T03:35:36 < kakimir> controlled voltage
2015-09-05T03:37:56 < kakimir> they have 4 tx streams that they cut as low as possible with those ldos?
2015-09-05T03:41:49 < PeterM> i thought a lot of mobilephone stuff was super integrated, like the SoCs had integrated, digitally controlled switching supplies
2015-09-05T03:44:33 < kakimir> isn't there like single chip solutions already
2015-09-05T03:46:36 < kakimir> add some passives and done
2015-09-05T03:50:52 < PeterM> yes and no, like the SoC will probably need like 1.2v,1.5v,1.8v, and it will have regulators for those built in, then oyu have like chargepumps for the flashes and boost converters for the display backlights, some LDOs for the audio and stuff, then another set of supplies for all the rf stuff, though i think all the RF stuff is handled by a signle regulator though
2015-09-05T03:58:01 < kakimir> I have misunderstood these controlable regulators
2015-09-05T03:58:33 < kakimir> these are for whole set of peripherals

2015-09-05T05:57:50 < mtbg> I wonder why one would want to have +3.3 and +5V output on these converters, instead of VIO input for reference i/o voltage
2015-09-05T05:58:12 < kakimir> but I seriously recommend buying some JTAG/SWD debugger
2015-09-05T05:58:16 < mtbg> so that it could be suitable for any 1.8-5V uart

2015-09-05T05:59:16 < kakimir> right?

2015-09-05T10:09:27 < Yoduza> $2.13 ST-LINK on aliexpress. Is it clone ?
2015-09-05T10:10:01 < PaulFertser> Yoduza: see http://sourceforge.net/p/openocd/tickets/83/ it has a link to pastebin.
2015-09-05T10:10:30 < PaulFertser> R2COM: if you're interested, I know of these developments:
2015-09-05T10:13:12 < PaulFertser> R2COM: Milandr produces a range of Cortex-M3 and Cortex-M1-based microcontrollers. MCST produces hybrid DSP+ARM11 powerful SoCs. "Baikal" is developing some modern SoCs. Multiclet is advancing their own highly-parallel architecture. NIIET has a family of Cortex-M4-based micorcontrollers (NT32M4F1).
2015-09-05T10:13:57 < PaulFertser> I'm not involved in any of these.
2015-09-05T10:14:32 < PaulFertser> And in the long run I think Russia is going to fail very very hard...
2015-09-05T10:14:44 < Yoduza> ARM7 start from $5 per chip on aliexpress, Lol
2015-09-05T10:15:19 < PeterM> important question: how long until i can buy them on digikey?
2015-09-05T10:15:34 < PaulFertser> I'm afraid that's not our case. Russian people seem to be uninterested in going forward.
2015-09-05T10:17:04 < PaulFertser> PeterM: some of the stuff is available on local market. For some purposes (certain military equipment) you're not even allowed to use anything but those items I mentioned.
2015-09-05T10:17:30 < Yoduza> what is that monstr ESP8266 ?
2015-09-05T10:19:33 < PaulFertser> R2COM: the problem with working with military here is that it's often really underpaid and ridiculously silly at the same time. I.e. it's like they're developing something relatively cool and modern but have to put up with constant everyday brain fucking with lousy job conditions.
2015-09-05T10:20:27 < Yoduza> go on #politics with this thema
2015-09-05T10:20:41 < Yoduza> this is place for right humans
2015-09-05T10:20:48 < PaulFertser> R2COM: our factory is producing some high-end mil stuff, so I know what I'm talking about. Also, they're mostly using Xilinx FPGAs with PPC cores in metal-ceramic packages, not really custom stuff.
2015-09-05T10:21:16 < PaulFertser> Yoduza: you do not tell me where to go, ok?
2015-09-05T10:21:45 < PaulFertser> R2COM: I'm just telling you why I'm not involved with MCST or some such.
2015-09-05T10:22:08 < PaulFertser> I have an impression what I describe is applicable to most of our high-tech mil-oriented companies.
2015-09-05T10:22:23 < PaulFertser> I know one guy working in mcst.
2015-09-05T10:22:40 < PaulFertser> I do
2015-09-05T10:22:56 < Yoduza> my chief brother is top manager in xilinx. So?
2015-09-05T10:23:50 < jpa-> is this a contest?
2015-09-05T10:24:15 < PeterM> NIIET  seems to just clone western stuff
2015-09-05T10:24:20 < PaulFertser> R2COM: were you living here, I'm sure you'd be of big benefit to our industry, no kidding. You've just the right attitude plus plenty of required skills.
2015-09-05T10:25:07 < PeterM> or is their website just... not maintained?
2015-09-05T10:25:31 < PaulFertser> Haha, reminds me of cardinality, trans-finite induction etc.
2015-09-05T10:26:44 < PaulFertser> PeterM: well, if one wants to use stm32 but needs to go beyond -40C common industrial temperature grade, what would he do?
2015-09-05T10:28:03 < PaulFertser> R2COM: what I know is that RTI (Mints' institute) is having difficulties hiring and keeping good developers.
2015-09-05T10:28:23 < PaulFertser> Of course, AK-47 is long deprecated, you know it much better than me.
2015-09-05T10:29:06 < PeterM> PaulFertser, cry themselves to sleep
2015-09-05T10:29:24 < PaulFertser> R2COM: I mean there's AKS-74U etc.
2015-09-05T10:29:54 < PaulFertser> PeterM: wrong, they just go to milandr or niiet and get similar functionality in a package that allows -50C.
2015-09-05T10:30:43 < PeterM> NIIET don't seem to have any 32bit on theri website, or is it not maintained, as i asked?
2015-09-05T10:31:04 < PeterM> or is this contact sales only
2015-09-05T10:31:29 < PaulFertser> PeterM: I judge by http://openocd.zylin.com/#/c/2658/
2015-09-05T10:31:33 < PeterM> Milandr MDR32F9Qx looks nice though
2015-09-05T10:32:23 < PaulFertser> All of them do not care about EN translations of their websites, that's true.
2015-09-05T10:32:31 < GargantuaSauce> wouldn't be hard to have a small insulated heated chamber also to keep it from ever hitting <-40
2015-09-05T10:33:06 < GargantuaSauce> definitely
2015-09-05T10:33:27 < GargantuaSauce> also are there even battery chemistries that work past that?
2015-09-05T10:34:06 < PeterM> GargantuaSauce, many, just limited capacity or internal resistance
2015-09-05T10:34:17 < PeterM> well, ionic resistance rather
2015-09-05T10:35:05 < PaulFertser> R2COM: I talked to some managers at RKK "Energy" recently. They're trying to recruit C-grade students to work for them. When asked a direct question, I got an explanation that an A-grade person would certainly not be willing to stay there for longer than two years.
2015-09-05T10:35:39 < PaulFertser> I mean skills, talent and attitude.
2015-09-05T10:35:44 < PaulFertser> Not real grades.

2015-09-05T10:40:01 < PaulFertser> Nope, not dead. What military folks do right is that they have strict QA requirements plus enormous redudancy that commercial companies can rarely afford. So they get the desired results even with low-quality components, software, developers and support.

2015-09-05T10:42:07 < PaulFertser> R2COM: I do not need anybody to value my skills. I have a more direct way to evaluate it: by practical results.
2015-09-05T10:44:22 < PaulFertser> R2COM: nope, I have full schematics, installation manuals and ssh access to "testing firmware".
2015-09-05T10:44:37 < PaulFertser> R2COM: and I also talk to developers who implement it.
2015-09-05T10:45:45 < PaulFertser> When a person writes several programs that should run on a multi-tasking OS and each will take 100% CPU time, that tells a lot to me. When they provide totally unmaintainable basic-style buggy Python GUIs to test their equipment, that's not a good sign either.
2015-09-05T10:46:38 < PaulFertser> RTI Mints
2015-09-05T10:47:19 < PaulFertser> Who are the real stars here?
2015-09-05T10:47:27 < PaulFertser> (i mean here in russia)

2015-09-05T10:52:09 < PaulFertser> I wished to be farther.
2015-09-05T10:53:06 < PaulFertser> R2COM: are you trying to mock me just because I do not like mil equipment and related mindset or is there another reason?
2015-09-05T10:54:06 < PaulFertser> I think I can too, why not?
2015-09-05T10:55:37 < PaulFertser> With recent "advances" in world perception of local population I'm more and more likely to do that, indeed.

2015-09-05T10:58:36 < PaulFertser> You had your reasons to leave. I still have some reasons to stay. But you can bet it's not lack of skills.
2015-09-05T10:59:35 < PaulFertser> Granted, you're 100x more skilled in EE than me. But I have some interesting experience in practical software development. That's more than enough to get by anywhere in the "civilised" word.
2015-09-05T11:03:45 < PaulFertser> I'm also biased against any military, and I want all of them to fail, so of course I'm not fair. But when it comes to the facts, I say no lies, just what I see myself. I agree I'm seeig just a small part of the picture. If you know happy people who work on S-400, great, you see another part and it looks better, I'm in no position to question that.

2015-09-05T13:05:45 < Laurenceb__> it has pretty lame peripherals and fairly poor sleep modes
2015-09-05T13:10:31 < Yoduza> for calculations its best choice. 96KB data ram, 64KB code ram
2015-09-05T13:10:31 < PeterM> Yoduza, what core does it use? 8051? 6502?

2015-09-05T13:11:30 < Yoduza> RISC
2015-09-05T13:11:50 < PeterM> RISC isn't a core...
2015-09-05T13:12:35 < Yoduza> The core is a 106micro Diamond Standard core (LX3) made by Tensilica
2015-09-05T13:14:21 < Yoduza> so, now $5 for Cortex-M3 not good idea :D
2015-09-05T13:14:23 < PeterM> is there mainstream support for  that core in other micros?
2015-09-05T13:14:46 < Yoduza> WIFI in there is chip include as a core !!!

2015-09-05T17:06:50 < emeb> Steffanx: so sarcastic
2015-09-05T17:07:26 < Steffanx> Yes and no emeb. I can't figure out if it was meant sarcastic or if i really miss it  :D
2015-09-05T17:07:33 < Steffanx> *missed
2015-09-05T17:08:13 < emeb> I suppose the "missing" something doesn't necessarily mean you're glad when it comes back.
2015-09-05T17:08:23 < dongs> oh, im sure he's glad.
2015-09-05T17:08:27 < dongs> ^_-

2015-09-05T17:14:39 < Steffanx> Very unlikely as digikey has them for $16+

2015-09-05T17:19:03 < emeb> why not?
2015-09-05T17:19:17 < dongs> have to solve the zano problem of image being bigger than ram

2015-09-05T17:20:22 < dongs> qyx_: tl;dr, can you pull image from camera slowly if you just need a still shot?
2015-09-05T17:21:01 < qyx_> i was doing jpeg only
2015-09-05T17:21:05 < dongs> right, jpeg
2015-09-05T17:21:09 < dongs> but f103 only has 20k ram
2015-09-05T17:21:18 < dongs> were you loading entire image at once?

2015-09-05T17:26:25 < qyx_> no github activity from April
2015-09-05T17:26:37 < dongs> if you have some space to store your frames which is fast enough (ie. it can save the frame faster than the camera outputs it), you can use small SRAM buffer and use DMA circular mode. In this case you need to signal the semaphore on half transfer and transfer complete interrupt and process both buffer halves continuously.
2015-09-05T17:26:49 < qyx_> wat
2015-09-05T17:26:55 < dongs> .. in your page
2015-09-05T17:27:06 < qyx_> ah

2015-09-05T17:28:27 < dongs> too much
2015-09-05T17:28:28 < qyx_> with 64-128K
2015-09-05T17:28:37 < dongs> i think ~$5-ish
2015-09-05T17:28:41 < qyx_> meh
2015-09-05T17:28:48 < dongs> o duno about 401/411. 405 is that.
2015-09-05T17:28:51 < dongs> but if im using F4 i might as well use DCMI
2015-09-05T17:28:59 < qyx_> 405 is different

2015-09-06T02:17:54 < PeterM> upgrdman, there is only one decent sync sepic controller and thats from LT iirc, but you could probably get some fet drivers and do it with stm
2015-09-06T02:18:16 < upgrdman> ya im doing it with stm32f0
2015-09-06T02:18:30 < upgrdman> http://www.farrellf.com/temp/sepic_converter_revA.jpg
2015-09-06T02:18:45 < upgrdman> manually right now, but will write up a control loop if this pans out
2015-09-06T02:19:05 < PeterM> ermm...
2015-09-06T02:19:12 < PeterM> you clearly have wound 2 inductors
2015-09-06T02:19:22 < PeterM> why didnt you just put both windings on one core?
2015-09-06T02:19:41 < upgrdman> i didnt wind them :)
2015-09-06T02:19:46 < PeterM> o
2015-09-06T02:19:55 < upgrdman> they were pulled from shitty rc battery charger
2015-09-06T02:19:56 < PeterM> ugly AF toroids tehn
2015-09-06T02:20:03 < upgrdman> yes
2015-09-06T02:20:06 < PeterM> ahh, 'plains it
2015-09-06T02:20:37 < upgrdman> if i was going to hand wind them, i'd use multiple strands of thinner wire. 'cause skin effect.
2015-09-06T02:20:38 < PeterM> you can use one toroid wiht 2 windings of about 1/2 the total number of turns
2015-09-06T02:20:44 < PeterM> saving on copper losses and board space
2015-09-06T02:20:49 < PeterM> i cant rememebr the phasign dots
2015-09-06T02:23:56 < PeterM> p[fet rectification on secondary is easiest ync rect, but ofc, use a schottky paralel to pfet so you avoid turning on body diode
2015-09-06T02:24:21 < upgrdman> ync?
2015-09-06T02:24:27 < upgrdman> or sync

2015-09-06T07:23:11 < PaulFertser> emeb_mac: there're out of tree patches by ST themselves, unmergeable because code quality. And there're better patches in the works, hold on, I'll get you a link.

2015-09-06T07:27:16 < PaulFertser> emeb_mac: git fetch http://openocd.zylin.com/openocd refs/changes/40/2940/4 ; git checkout FETCH_HEAD; this will give you stm32f7 support in stm32f2x driver. git fetch http://openocd.zylin.com/openocd refs/changes/54/2754/5 here configs but not rebased on the very latest patch, you can cherry-pick them or just checkout, even non-latest should work good.

2015-09-06T07:33:06 < upgrdman> any idea why this gate would be taking a few us to drive high? im using an IRS2301S gate driver, which should have a Ton of about 220ns. blue waveform is the gate:  http://www.farrellf.com/temp/sepic_waveforms.png
2015-09-06T07:37:41 < dongs> PaulFertser: duno man, i was just reading some trash about ass10k and it said they werent supporting it.
2015-09-06T07:37:50 < dongs> NOT that i care, i would never run opensauce on a wifi bridge

2015-09-06T07:41:07 < PaulFertser> dongs: ubnt runs Linux (the kernel) plus QCA shit-SDK, so you are running opensource, just not fully. Also, you apparently have very ordinary usecases, those that are covered by the manufacturers and do not use SOHO-grade equipment. Isn't it great that one can get a shitty dlink or whatever, it doesn't work stable with vendor firmware, it doesn't provide VLANs, IPv6, support for modern USB LTE
2015-09-06T07:41:13 < PaulFertser> sticks, printers, etc etc, you install OpenWrt on it and get fully reliable fully functional advanced AP+router+print server etc?

2015-09-06T08:01:59 < PaulFertser> dongs: I know right, sometimes it works, sometimes not. Sometimes it works and then they buy a new GSM/UMTS/LTE modem and it doesn't. Also, the vendor firmware is often unstable. Seen that first-hand. Shit needs rebooting every week while the very same board works 100% solid with OpenWrt.
2015-09-06T08:02:46  * emeb_mac installed dd-wrt on an ancient linksys router. works great and has lots of useful features that the original didn't

2015-09-06T08:03:49 < emeb_mac> not mine - installed it as a repeater at the in-law's house.

2015-09-06T08:06:06 < upgrdman> i had to go to AC because G sucks ass
2015-09-06T08:06:26 < upgrdman> my internet connection is 60Mbps, so G was slower than my net connection
2015-09-06T08:06:49 < dongs> yeah i ordered some archer tpdick thing. but the idiot korean sent it by registered mail instead of EMS, so instead of it arriving 2 days later its still somewehre on shitty korean boat

2015-09-06T08:07:40 < upgrdman> lol
2015-09-06T08:07:54 < emeb_mac> so WRT54G is fine for them
2015-09-06T08:08:27 < upgrdman> that's one thing that pissed me off about my university. im in a nice uni in southern california, and students get like 6Mbps max. total wtf.
2015-09-06T08:08:58 < dongs> why do you think students need internet?
2015-09-06T08:09:02 < upgrdman> it used to be that uni's were the only place with decent internet access. now it's the opposite. fuckign mcdonalds offers faster wifi

2015-09-06T08:10:28 < upgrdman> i think im most pissed that the uni only allows ports 80 and 443, prolly because of torrenter faggots. so no irc unless i use webchatr

2015-09-06T10:05:13 < upgrdman> yes. c2 is approx 250uF
2015-09-06T10:05:26 < upgrdman> that ringing is not on the output voltage
2015-09-06T10:05:52 < upgrdman> its at the diode anode, not cathode
2015-09-06T10:08:09 < artag> poke your finger on the circuit, see what changes the ringing frequency, then look for a resonant circuit
2015-09-06T10:08:23 < artag> maybe some wire loop due to the test layout
2015-09-06T10:08:51 < Fleck> upgrdman: whats the blue channel?
2015-09-06T10:09:01 < upgrdman> gate
2015-09-06T10:09:03 < artag> your 250uF won't see that at all, you'd need a small fast cap close to the switch
2015-09-06T10:10:30 < Fleck> also you can see ringing in gate too
2015-09-06T10:14:21 < upgrdman> wonder if the ringing on the anode is from C1 charging up and L2 not being happy about current dropping toward zero.

2015-09-06T11:57:04 < PeterM> upgrdman, i think the ringing is because there is no low esr input capacitance, and possibly because your gate drive lead is so long as passes close to hte input inductor
2015-09-06T11:57:36 < PeterM> if it is still http://www.farrellf.com/temp/sepic_converter_revA.jpg this
2015-09-06T11:58:38 < PeterM> well, not so much the input inductor but is prone to induced current

2015-09-06T17:48:22 < kakimir> had waterproof android for last 5years
2015-09-06T17:48:32 < zyp> sure, but buoyant
2015-09-06T17:48:40 < zyp> that would mean it has less density than water
2015-09-06T17:49:03 < zyp> which would imply that it's huge and empty

2015-09-06T18:08:18 < zyp> buoyancy would require it to be twice as thick or so

2015-09-06T18:10:25 < karlp> I have that steel dtse9 usb stick jpa linked to, it's great design, but it's a pretty shitty slow stick.
2015-09-06T18:10:44 < zyp> jpa-, if you want to make a buoyant phone, you might as well just glue a floatation pad to the back of a normal waterproof phone
2015-09-06T18:10:55 < jpa-> zyp: yeah
2015-09-06T18:11:12 < jpa-> i actually dunked my phone just today.. we'll see if it survives :P
2015-09-06T18:11:36 < Steffanx> the good old finnish nokia 3310 survives everything
2015-09-06T18:11:43 < Steffanx> or do you have something more fancy than that?
2015-09-06T18:12:06 < zyp> I actually broke a 3310 once
2015-09-06T18:12:12 < zyp> I dropped it on a tiled floor
2015-09-06T18:13:11 < jpa-> Steffanx: well fancier nokia, but yeah the chances are pretty good that it will survive
2015-09-06T18:13:20 < jpa-> what is surprising is that it turned off when it got wet
2015-09-06T18:14:04 < jpa-> but that seems to be due to the battery somehow
2015-09-06T18:14:15 < jpa-> protection circuit is probably confused

2015-09-06T20:00:11 < Tectu> like uGFX, runs on quite a few LPC based products :)
2015-09-06T20:00:29 < kakimir> you know that big bucks rule
2015-09-06T20:00:46 < Tectu> the bigger the bucks the shittier the outcome?
2015-09-06T20:00:54 < kakimir> true
2015-09-06T20:01:10 < Tectu> doesn´t always apply, luckily
2015-09-06T20:01:18 < Steffanx> Tectu fix your ' key
2015-09-06T20:01:24 < Steffanx> or remove the `
2015-09-06T20:01:30 < Tectu> Steffanx, it works fine in EVERY application but HexChat
2015-09-06T20:01:33 < Steffanx> i mean the other one that write that
2015-09-06T20:01:38 < Tectu> ´
2015-09-06T20:01:39 < Steffanx> *to
2015-09-06T20:01:41 < Tectu> `
2015-09-06T20:01:43 < Tectu> can do that too ^
2015-09-06T20:01:48 < Steffanx> i cant even do that one
2015-09-06T20:01:59 < Tectu> need to go US keyboard then
2015-09-06T20:02:02 < Taxman> `´#
2015-09-06T20:02:13 < Tectu> anyway, ¨  <--- that is how my quotes look in this HexChat thingy
2015-09-06T20:02:14 < Taxman> '´`
2015-09-06T20:02:19 < Tectu> while it loosk just fine everywhere else
2015-09-06T20:02:21 < Steffanx> no such key on us keyboard afaik.
2015-09-06T20:02:25 < Tectu> hint: the ´ and ¨ are the same key
2015-09-06T20:02:30 < Steffanx> '
2015-09-06T20:02:35 < Fleck> gtk have had problems with symbols for years...
2015-09-06T20:02:36 < Tectu> Steffanx, I got an official us keyboard from usa and it has one
2015-09-06T20:02:50 < Tectu> Steffanx, also german crap does that too
2015-09-06T20:02:51 < Steffanx> ' and "  are on the same key
2015-09-06T20:02:54 < Tectu> Steffanx, and swiss german crap too
2015-09-06T20:03:04 < Tectu> Steffanx, yep, and when I do what you did:    ´ and ¨
2015-09-06T20:03:19 < Steffanx> so you'r doing it wrong
2015-09-06T20:03:39 < Tectu> not sure, it works in everything outside hexchat
2015-09-06T20:05:13 < Tectu> anyway, to get back to the topic: Sometimes I even put a dedicated BMP on my board
2015-09-06T20:05:17 < Tectu> (when money is no issue)
2015-09-06T20:05:30 < Tectu> but after all an STM32F102CB and some silly USB connector aren´t expensive
2015-09-06T20:05:35 < Tectu> and then load the thing via DFU
2015-09-06T20:12:30 < emeb> interesting idea
2015-09-06T20:12:51 < Tectu> well, on a board that costs 300 USD I don´t mind paying 4 more dollars for a buil-in debugger :)
2015-09-06T20:15:32 < emeb> Tectu: maybe you know - I have a little flashing recipe for my makefile that uses gdb + BMP to load code
2015-09-06T20:15:51 < Tectu> emeb, interesting
2015-09-06T20:16:02 < emeb> there's a .gdbinit file that defines some processes to attach, set the elf file
2015-09-06T20:16:07 < Tectu> emeb, when working with openocd I always put a function in there for loading the stuff and just call that out of the makefile
2015-09-06T20:16:29 < emeb> yes, I do to
2015-09-06T20:16:34 < emeb> just 'make flash'
2015-09-06T20:16:47 < emeb> it can either use openocd or gdb+bmp
2015-09-06T20:17:12 < emeb> but when gdb exits in batch mode, my terminal session is in a weird state
2015-09-06T20:17:15 < Tectu> emeb, eg. this one I use for the F7 disco: http://paste.ugfx.org/show/dbcab46e2d
2015-09-06T20:17:26 < emeb> doesn't echo to screen when I type.
2015-09-06T20:17:37 < emeb> so I have to issue a 'reset' command
2015-09-06T20:17:50 < emeb> which clears the screen and loses any msgs from gdb
2015-09-06T20:17:59 < emeb> that only seems to happen in batch mode.
2015-09-06T20:18:22 < Tectu> uhm, no idea, sorry
2015-09-06T20:18:41 < emeb> np - thx anyway
2015-09-06T20:21:20 < Tectu> welcome
2015-09-06T20:21:33 < Tectu> emeb, I can ask andrew if you want
2015-09-06T20:21:57 < emeb> Tectu: sure - who's andrew and why would he know better? :)
2015-09-06T20:23:13 < Tectu> emeb, because he has about 30 years of GDB, make and other painful software experience ;)
2015-09-06T20:23:30 < Tectu> emeb, whenever I have a GDB / make issue I ask him
2015-09-06T20:23:31 < emeb> sounds like the guy who would know.
2015-09-06T20:23:33 < Steffanx> and still he writes terrible makefiles :P
2015-09-06T20:23:48 < Tectu> Steffanx, syntax wise, yes :D
2015-09-06T20:24:04 < Steffanx> but makefiles..
2015-09-06T20:24:37 < Tectu>  $(foreach drv,$(DRIVELETTERS),$(foreach var,$(PATHEXPAND),$(eval $(var):=$$(patsubst $(drv):%,/cygdrive/$(drv)%,$($(var))))))
2015-09-06T20:24:38 < emeb> note that this terminal lockup behavior started when I updated to the 4.9 version of launchpad gcc
2015-09-06T20:25:00 < emeb> so I assume it's something in the arm-none-eabi-gdb
2015-09-06T20:25:05 < Tectu> emeb, oh
2015-09-06T20:25:30 < emeb> and it seems to only happen when I do --batch on the command line.
2015-09-06T20:25:40 < emeb> (or --batch-silent)
2015-09-06T20:25:52 < Tectu> emeb, try #workingset

2015-09-07T01:21:30 < kakimir> plastic is for the poor
2015-09-07T01:22:26 < upgrdman> wtf. black magic probe is $60 ?! is it that fucking hard to get openocd working with an stlinkv2? even i managed to do it.
2015-09-07T01:23:32 < kakimir> how about openocd and jlink clone
2015-09-07T01:23:37 < kakimir> beats stlink
2015-09-07T01:25:31 < upgrdman> R2COM, well a polish stlinkv2 clone is like $5 on ebay
2015-09-07T01:25:35 < upgrdman> err polished
2015-09-07T01:26:23 < upgrdman> how would they be illegal? might be against  STM TOS but who cares
2015-09-07T01:26:56 < upgrdman> regardless, $60-75 for a programmer/debugger is insane. esp when it's just another stm + mini usb on a pcb
2015-09-07T01:27:04 < upgrdman> china
2015-09-07T01:27:06 < upgrdman> shenzhen
2015-09-07T01:27:30 < upgrdman> they also super small and have a case
2015-09-07T01:28:16 < upgrdman> ya but for something with a BOM cost of <$2, wanting $60+ is rediculous.
2015-09-07T01:28:40 < upgrdman> that's even more than we medical companies rape our customers ;)
2015-09-07T01:28:57 < upgrdman> for a BMP?
2015-09-07T01:29:23 < upgrdman> it's not a "finished product" it doesnt even have a case
2015-09-07T01:30:05 < upgrdman> i dont see an FCC / UL / etc logo, do you?
2015-09-07T01:39:07 < kakimir> does blackmagic even have their own software?
2015-09-07T01:39:18 < upgrdman> ya on shithub
2015-09-07T01:39:25 < upgrdman> its open sauce
2015-09-07T01:39:35 < kakimir> then it's crazy
2015-09-07T01:39:58 < kakimir> somebody quickly clone it
2015-09-07T01:40:16 < kakimir> sell for 20$ and gain profits
2015-09-07T01:48:35 < upgrdman> ya
2015-09-07T01:48:41 < upgrdman> and the china clone even comes in a nice case
2015-09-07T01:48:44 < upgrdman> looks pro
2015-09-07T01:49:41 < upgrdman> here's mine with the pogo pins that i added: http://www.farrellf.com/temp/pogo_pin_programmer.jpg
2015-09-07T01:50:57 < upgrdman> now if only someone could take that clone xilinx/altera/lattice combo jtag'er and make it that small and pro looking :)

2015-09-07T02:20:11 < kakimir> just for curiosity?
2015-09-07T02:20:17 < upgrdman> just to expand my knowledge
2015-09-07T02:20:19 < upgrdman> ya
2015-09-07T02:20:38 < upgrdman> plan to try Cùk afterwards
2015-09-07T02:20:43 < upgrdman> maybe flyback too
2015-09-07T02:21:03 < kakimir> do you have any applications in mind?
2015-09-07T02:21:44 < upgrdman> tempted to make a DC UPS but it's at the bottom of my list of shit to do
2015-09-07T02:22:20 < upgrdman> i bought some new Pb batteries to fix my AC UPS, so i have a few years before they shit the bed again
2015-09-07T02:22:49 < upgrdman> was kinda pissed when i went to a store and they wanted $30 for a 12V 7Ah battery. so i bought them on amazon for like $16
2015-09-07T02:22:52 < Roklobsta> upgrdman: you using your linear algebra and Laplace transforms for loop analysis or you going all hacker and just using Wikipedia's entry on PID controllers?
2015-09-07T02:23:24 < upgrdman> even more ghetto. im using shit i have laying around, and see how badly it performs, then making adjustments :)
2015-09-07T02:24:10 < Roklobsta> nice
2015-09-07T02:24:21 < Roklobsta> have fun with the flyback.
2015-09-07T02:24:27 < emeb> tuning control loops is best done empirically
2015-09-07T02:24:28 < upgrdman> and right now i dont even have a control loop on the SEPIC. just my hand turning a pot, and my customer servo tester thinggy generates pwm
2015-09-07T02:24:30 < Roklobsta> or should i say, fryback.
2015-09-07T02:24:42 < upgrdman> ya
2015-09-07T02:24:50 < upgrdman> CV/CC PSU saves my ass so many times
2015-09-07T02:25:03 < upgrdman> glad i bought a beefy one. 32V 30A
2015-09-07T02:25:12 < Roklobsta> a welder.
2015-09-07T02:25:31 < Roklobsta> good for clearing out PWR/GND shorts.
2015-09-07T02:25:50 < upgrdman> just pop the offending IC :)
2015-09-07T02:26:43 < upgrdman> i must say i am disappointed in the IRS2301S gate drivers. thought their 150mA of current would be enough. not really if you want supersonic PWM

2015-09-07T04:00:23 < karlp> that one is a snippet of a vid that someone else posted here a few weeks ago iirc
2015-09-07T04:01:25 < dongs> upgrdman: that was a retweet from another channel that was a 4chan link
2015-09-07T04:01:50 < upgrdman> k
2015-09-07T04:02:46 < upgrdman> i recall someone saying mouser offered free shipping for $100+ a long time ago. i don't see that. anyone know if it's still going on?
2015-09-07T04:02:54 < kakimir> yes
2015-09-07T04:03:04 < dongs> they do > $75 if you're not in U.S.
2015-09-07T04:03:22 < kakimir> 65EUR
2015-09-07T04:03:22 < dongs> i duno if any of freeship deals on digikey/mouser apply to u.s. customers
2015-09-07T04:03:24 < upgrdman> lolwut. so if they ship internationally it'll be free? fuck me.
2015-09-07T04:03:28 < dongs> yes
2015-09-07T04:03:44 < dongs> actually its 7500 jpy, which is more liek $62 now
2015-09-07T04:03:53 < upgrdman> i wonder why they do that. it costs MORE for intl shipping
2015-09-07T04:07:19 < dongs> cuz their intl prices are a tiny bit higher
2015-09-07T04:07:25 < upgrdman> oh
2015-09-07T04:07:34 < dongs> they dick the exchange rate a bit
2015-09-07T04:07:43 < dongs> anyway, <$75 shipping is only like $20
2015-09-07T04:07:57 < dongs> which is ~normal-ish for doing a lot of volume, chinagirl fedex pricing is similar
2015-09-07T04:08:34 < dongs> not even 4k
2015-09-07T04:08:36 < dongs> garbage
2015-09-07T04:08:42 < dongs> and huge as fuck
2015-09-07T04:10:52 < kakimir> remember when side by side crts were the thing?
2015-09-07T04:11:15 < dongs> its mostly the 34" part
2015-09-07T04:11:22 < dongs> that is huge
2015-09-07T04:11:35 < dongs> if its like your only monitor and you don't do anything on it actually then its probably ok!!!
2015-09-07T04:13:28 < dongs> duno. i think its too low rez for so huge.
2015-09-07T04:14:36 < dongs> Cons: No power supply. There is nothing more annoying than having a bad power supply on a monitor. This one is fine as of now, but I have had a lot of onboard power supplies die in monitors. I can't stand it. For the price dell is offering, give me an external PWS in the event it goes bad. I'd rather spend $100 on that than $700 on a new monitor.
2015-09-07T04:14:42 < dongs> haha

2015-09-07T05:02:01 < upgrdman> java applets were stupid
2015-09-07T05:02:06 < upgrdman> but java itself isnt too bad

2015-09-07T07:56:35 < dongs> .This means we.ve essentially future proofed the Zano hardware. However, as far as the current CAA regulations are concerned, Zano is fully compliant for consumer applications.
2015-09-07T07:57:44 < dongs> As far as Zano.s camera is concerned it has the ability to take high definition motion and still images as well as stream via Wifi to the user.s chosen device; in addition it can record in high frame rates for slow motion and virtual reality integration.
2015-09-07T08:03:33 < dongs> Whilst the first generation Zanos cannot fly in heavy rain there are plans to actually produce a fully-waterproof submersible model in the future, which will pretty much fulfil Crowther.s wish of making drone photography .available to everyone..
2015-09-07T08:03:41 < dongs> so much for future proofing???
2015-09-07T08:03:51 < dongs> why can't it handle trivial things like rain and submersion in water?
2015-09-07T08:03:56 < dongs> bullshit, i don't need to wait for a V2 for that

2015-09-07T13:08:18 < dongs> kinda
2015-09-07T13:08:24 < Ecco> Oh you mean special-made bottles? I thought you guys meant that I should pour the thing straight from the 1L bottle :)
2015-09-07T13:08:31 < Ecco> http://www.antistat.co.uk/shopimages/products/normal/146-0001_ESD%20Flux%20Bottle.jpg
2015-09-07T13:08:32 < ReadError> i just squirt it on the board from the bottle
2015-09-07T13:08:45 < ReadError> but use a noclean so cleanup is easy
2015-09-07T13:08:54 < PeterM> ecco, also, what kind of liquid flux? rosin, or no clean etc stuff?
2015-09-07T13:08:59 < dongs> i only use flux when hacking/desoldering
2015-09-07T13:09:12 < Ecco> Thing is, I can buy a syringe from my local pharmacy easily
2015-09-07T13:09:12 < ReadError> kester 951 is great ;)
2015-09-07T13:09:24 < dongs> yeah and ih ave a couple kester flux pens
2015-09-07T13:09:28 < ReadError> I bought like 10 bottles for super cheap
2015-09-07T13:09:36 < ReadError> guess people use them for repairing xbox
2015-09-07T13:09:38 < Ecco> This one
2015-09-07T13:09:39 < Ecco> http://www.batterfly.com/PDF/Catalogo_ESD/Tecnica%20Flussante%20MF220.pdf
2015-09-07T13:09:50 < dongs> why teh fuck i cant click that link
2015-09-07T13:09:55 < dongs> hm now i can
2015-09-07T13:09:56 < dongs> weird
2015-09-07T13:10:51 < Ecco> So supposedly "No clean"
2015-09-07T13:11:20 < PeterM> [20:08] <dongs> i only use flux when hacking/desoldering - same, but that is pretty often because i do much anal log shit that requires actual prototypes and actual wasting of money :(
2015-09-07T13:12:17 < PeterM> ecco ahh, yeah, decent stuff
2015-09-07T13:12:33 < Ecco> Great!
2015-09-07T13:12:40 < Ecco> Actually the shop (batterfly) is a nice one
2015-09-07T13:12:52 < Ecco> But that's pretty much the only reference they had
2015-09-07T13:13:05 < Ecco> So could I use a medical syringe for this flux?
2015-09-07T13:13:08 < dongs> @gillSpie - if anyone every fires up a Zano in a restaurant near me it will be getting a jug of water poured all over it!
2015-09-07T13:13:12 < dongs> Please, have some care about where you use these things. Just because you CAN use
2015-09-07T13:13:15 < dongs> something in a crowded restaurant does not mean you SHOULD use it there.

2015-09-07T13:19:26 < Ecco> PeterM: OK. What would be the issue with using a syring for SMD?
2015-09-07T13:19:37 < dongs> how exactly do you use flux?
2015-09-07T13:19:43 < Ecco> Well, I don't!
2015-09-07T13:19:51 < Ecco> That's the first time I'm buying some!
2015-09-07T13:20:18 < dongs> 1L is going to last you like years
2015-09-07T13:20:38 < dongs> i bought a 2Oz zephflux bottle liek 5 years ago
2015-09-07T13:20:43 < Ecco> I also got some gel one, 10cc
2015-09-07T13:20:43 < Fleck> hey Tectu
2015-09-07T13:20:44 < dongs> its half-full only because I spilled half of it
2015-09-07T13:20:53 < Ecco> :-D
2015-09-07T13:20:55 < Tectu> hey Fleck, how are you doing?
2015-09-07T13:21:00 < ReadError> its harder to meter flow w/ a syring
2015-09-07T13:21:04 < Fleck> good, thanks, you?
2015-09-07T13:21:08 < ReadError> a bottle you can place a drop easy
2015-09-07T13:21:12 < Tectu> I´m fine too!
2015-09-07T13:21:19 < Ecco> Hi Tectu :)
2015-09-07T13:21:30 < Tectu> Hey Ecco :)  Are you fine too? ;)
2015-09-07T13:21:40 < Ecco> Sure :)
2015-09-07T13:21:49 < Tectu> good :)
2015-09-07T13:22:48 < Ecco> I also purchased some additional solder
2015-09-07T13:22:58 < Ecco> I had a some Sn99Cu1
2015-09-07T13:23:04 < Ecco> and got some Sn60Pb40
2015-09-07T13:23:33 < Ecco> (with rosin core)
2015-09-07T13:23:41 < Ecco> which one would you recommend for SMD work?
2015-09-07T13:23:49 < Ecco> (and would it make a big difference anyway?)
2015-09-07T13:24:18 < Tectu> Ecco, I am a huge fan of Sn60Pb40
2015-09-07T13:24:24 < Ecco> ok :)
2015-09-07T13:24:44 < dongs> i only use leadfree
2015-09-07T13:25:06 < Ecco> Well, from what I understood leadfree is nicer on the environment but a bit harder to manipulate
2015-09-07T13:25:11 < Ecco> Given that I am a huge beginner…
2015-09-07T13:25:12 < Tectu> Ecco, I always use this: http://www.stannol.de/en/products/solder-wires/?tx_produktselektor_filter%5Baa_prod%5D=Kristall%20505&tx_produktselektor_filter%5Baction%5D=show&tx_produktselektor_filter%5Bcontroller%5D=Product
2015-09-07T13:25:20 < Tectu> Ecco, the 0.56mm version works very well for SMD for me
2015-09-07T13:25:25 < Ecco> ok
2015-09-07T13:25:34 < dongs> wat
2015-09-07T13:25:36 < dongs> not evne 0.3mm
2015-09-07T13:25:51 < Tectu> Ecco, definitely not the cheapest one out there but I don´t mind paying a bit more as I don´t use a roll each week
2015-09-07T13:26:07 < Tectu> Ecco, very easy to solder with that one. I can only recommend it
2015-09-07T13:26:09 < Ecco> Indeed
2015-09-07T13:26:37 < Ecco> I got this one, looks very similar: http://www.batterfly.com/shop/multicore/multicore-60en-502-5c-288606
2015-09-07T13:27:09 < Tectu> uh, mine was like 6 times that price
2015-09-07T13:27:21 < Ecco> batterfly.com is a great shop :)
2015-09-07T13:27:28 < Ecco> Very nice customer support, shipping is super fast
2015-09-07T13:27:48 < PeterM> if you are buying solder, and you want leaded, get 63/37 its eutectic
2015-09-07T13:28:04 < Ecco> huh?
2015-09-07T13:28:05 < PeterM> 60/40 is slightly cheaper but has a plastic state
2015-09-07T13:28:13 < Tectu> Ecco, http://www.distrelec.ch/en/solder-wire-sn60-pb40-500-50-mm-stannol-kristall-505-810633/p/18250026?q=stannol+kristall+505+0.5&page=2&origPageSize=25&simi=86.4

2015-09-07T13:28:37 < Tectu> Ecco, also, I never buy 500g :) 500g of solder is a shit load of solder
2015-09-07T13:28:51 < Tectu> PeterM, can you elaborate?
2015-09-07T13:29:13 < Tectu> PeterM, I learned what eutectic means in material technology crap course in uni but how does that relate to this
2015-09-07T13:30:55 -!- dekar [~dekar@46.243.86.234] has joined ##stm32
2015-09-07T13:31:54 < PeterM> tectu as the solder cools, it will reach a point where it is either liquid or solid, it means that as soon as its solid, its solid, you can bump it or whatever and its fine. 60/40 is nto eutectic, it has a plastic reguion, as it cools it passes though a region where the soler is incredibly maleable(sp?) and if you bump it your join will look ugly as fuck and may not work
2015-09-07T13:31:59 < jpa-> Tectu: eutectic goes immediately from molten -> solid, so you have less time to wiggle your hands around
2015-09-07T13:32:19 < dongs> protipc
2015-09-07T13:32:46 < Tectu> I see
2015-09-07T13:33:07 < Tectu> but it is 63/37 Sn/Pb?
2015-09-07T13:33:36 < Tectu> PeterM, actually I observed that behavior several times. never thought of looking out for a different mixture
2015-09-07T13:33:46 < Tectu> PeterM, I just try not to bump my hot shit

2015-09-07T13:39:53 < PeterM> i have a few different solder alloys floating around, i've got a spool of 50/50 1.6mm stuff i use for connectors and battery tabs etc (was cheap and you dont need to feed meters of it), 0.6mm SAC305 (96.5% tin, 3%silver 0.5% copper) for lead free, 63/37 0.4mm for leaded and a roll of 0.7mm Multicore HMP (93.5% lead, 5% tin, 1.5% silver) for high temp applications
2015-09-07T13:54:23 < Ecco> Well this is actually interesting: http://www.farnell.com/datasheets/315929.pdf
2015-09-07T13:54:57 < Ecco> (Long story short, that doc says that indeed 63/37 is better than 60/40, but the difference isn't that big)

2015-09-07T14:03:55 < xkonni> using it in another device the result looks like: http://i.imgur.com/Xhrm0Wl.png
2015-09-07T14:04:13 < dongs> Laurenceb would be interested
2015-09-07T14:05:43 < xkonni> alright... will stare at working vs not-entirely-working code again ;)
2015-09-07T14:06:34 < xkonni> probably just didnt set one stupid flag
2015-09-07T14:12:04 < Laurenceb> 168 dB maximum link budget
2015-09-07T14:12:06 < Laurenceb> nice
2015-09-07T14:14:18 < xkonni> Laurenceb: right now i'm at: it should send, but doesnt... hrhr
2015-09-07T14:14:51 < Laurenceb> I've always used silabs
2015-09-07T14:15:07 < jpa-> xkonni: so what is at the other end? lora gateway?
2015-09-07T14:15:14 < Laurenceb> tbh I'm not convinced lora has any massive advantages
2015-09-07T14:15:38 < jpa-> Laurenceb: the prospect of operator-operated lora networks seems quite nice
2015-09-07T14:15:59 < Laurenceb> jpa-: but 2FSK is about as good
2015-09-07T14:16:09 < xkonni> jpa-: i have several, working, stm32 primer kits, now planning to use the sx1276 boards on a minnowboard
2015-09-07T14:16:23 < Laurenceb> certainly with FEC, but you can get almost the same performance with short packets and ACK
2015-09-07T14:16:48 < xkonni> as a control channel for a high-rate but not always available channel
2015-09-07T14:17:10 < xkonni> so technically this is not entirely stm32...

2015-09-07T14:18:24 < xkonni> actually that would be more than enough... the actual work is on the other channel
2015-09-07T14:18:38 < xkonni> just need 'some' reliable control channel and we had some of the lora boards

2015-09-07T15:25:25 < dongs> I believe that everything has been completed (quite some paper trail) and we are simply waiting for the compliance certificates. I had an update on friday given to me about this and that is what I was told.
2015-09-07T15:25:29 < dongs> As soon as I hear anything, I will let you know.
2015-09-07T15:25:45 < dongs> don't you already know your FCCID at this point tho?

2015-09-07T15:28:15 < dongs> Absolutely and I apologise for the recent lack of videos. Things popped up that distracted me from my tasks. We have a few app issues and the guys have a short window to get them fixed so that jumped up the priority list quite a bit. We had 15 Zano's to fly test off the new app but the app was not being reliable in flashing and configuring the Zano's.
2015-09-07T15:28:45 < dongs> The weather is quite nice this week here (nice as in not freezing or raining) so I will be doing quite a bit of outdoor flying, testing and tuning. I even plan to use the range extender in a nice open area and get some speed up. I will video as much of this as I can and share it with you all
2015-09-07T15:30:33 < dongs> The GPS modes including follow me will be included late this week, early next week. So technically v1.1 but its so early on, we may just keep it as v1.0 and update the release number instead of the sub version.
2015-09-07T15:32:39 < dongs> The GPS code is all in the Zano OS as of right now and in all Zano's being shipped too. The difference is I haven't enabled it through configuration on those Zano's and will do so the moment I am happy it is working.
2015-09-07T15:32:43 < dongs> So functionality is completed and included right now but not enabled. There is lots of stuff disabled in the current version, things we built in ages back but we will enable them slowly over time as we test and test and test them until we are happy.
2015-09-07T15:32:48 < dongs> haha

2015-09-07T15:45:59 < dongs> very easy
2015-09-07T15:46:18 < zyp> but why?
2015-09-07T15:46:33 < dongs> zyp, im about to put a F407VG into a design and i wasnt gonna draw it from scratch
2015-09-07T15:46:54 < dongs> and ciiva lib is handy for this.
2015-09-07T15:47:06 < dongs> i will still use my own footprint tho
2015-09-07T15:47:14 < Ecco> Oh nice
2015-09-07T15:47:18 < Ecco> how do you do this dongs?
2015-09-07T15:47:39 < Ecco> I tried to "tap" into the ciiva library but never figured out how
2015-09-07T15:48:06 < dongs> Ecco: i ahve circuitdonger in vmware, it does cache some files locally and altium opens them.
2015-09-07T15:48:13 < Ecco> nice :)
2015-09-07T15:48:17 < dongs> so i dir/s to find the .schdoc, load into altium and copypaste component.
2015-09-07T15:48:23 < Ecco> Smart
2015-09-07T15:48:29 < Ecco> I wanted to tcpdump circuitmaker
2015-09-07T15:48:54 < Ecco> Because I'm pretty sure it's possible to add the Ciiva library into stock Altium as a "vault"
2015-09-07T15:49:08 < Ecco> s/pretty sure/believing/
2015-09-07T15:51:12 < dongs> shit, i just noticed F407 is 210DMIPS
2015-09-07T15:51:15 < dongs> almost beating zano
2015-09-07T15:51:18 < dongs> *and* has DCMI
2015-09-07T15:51:23 < dongs> and SDIO
2015-09-07T15:51:28 < dongs> dick32 has neither
2015-09-07T15:51:47 < dongs> how they're goin to write 30mbit stream of JPEG aids to SDcard withotu SDIO i have no idea
2015-09-07T15:53:46 < Laurenceb> spi
2015-09-07T15:53:47 < Laurenceb> lul
2015-09-07T15:53:57 < dongs> yeah right
2015-09-07T15:54:11 < Laurenceb> how will they do video and streaming?
2015-09-07T15:54:19 < dongs> mjpeg streaming
2015-09-07T15:54:22 < dongs> last i heard
2015-09-07T15:54:27 < dongs> ivan was thinking of running camera at 60fps
2015-09-07T15:54:33 < dongs> capturing a 320x240 image
2015-09-07T15:54:37 < dongs> then a 1080p image
2015-09-07T15:54:43 < dongs> every 1/60th frame
2015-09-07T15:54:49 < dongs> i dont think its going to work like that :)
2015-09-07T15:55:03 < dongs> ugh
2015-09-07T15:55:08 < dongs> trying to do anything in circuitmaker is PAINFUL
2015-09-07T15:55:22 < dongs> i know all the fucking key shortcuts to do all the stuff in altidong but i ahve to spend hours looking at the dumb ribbon
2015-09-07T15:55:26 < dongs> to find same shit in circuitdonger
2015-09-07T15:56:06 < Laurenceb> more like bitchmaker
2015-09-07T15:56:10 < Laurenceb> it makes you its bitch
2015-09-07T15:57:45 < mtbg> they have some bigger plans
2015-09-07T15:57:46 < mtbg> Expected through software updates:

2015-09-07T15:57:47 < mtbg> [1.2] 360 and 180 degree Panoramics
2015-09-07T15:58:01 < scrts_w> what's the last update from zano?
2015-09-07T15:58:41 < Laurenceb> hahah WTF
2015-09-07T15:59:05 < Laurenceb> they are on crack
2015-09-07T15:59:13 < dongs> manchild dreams
2015-09-07T15:59:22 < dongs> they think if they throw money on something, it will happen

2015-09-07T16:35:27 < __rob2> dongs, you use Altium ?
2015-09-07T16:36:11 < dongs> sure
2015-09-07T16:36:37 < __rob2> how do you deal with overlapping thermals ?
2015-09-07T16:36:55 < __rob2> so I have a few vias close to each other, and the thermal cut outs overlap and create a right mess
2015-09-07T16:37:38 < dongs> er, define "overlapping"? i have vias in epads but they're like some spaces apart

2015-09-07T16:39:10 < dongs> thats on plane layer?
2015-09-07T16:39:14 < dongs> you can turn that off uhh

2015-09-07T16:47:25 < dongs> oh, found
2015-09-07T16:47:28 < dongs> it was in DRC
2015-09-07T16:47:29 < dongs> Thermals are connections to the plane with thermal relief 'cutouts' around them to reduce heat conductivity to the plane copper. Thermals can become 'starved' when the surface area of the copper spokes connecting it to the plane is reduced by void areas. This rule also checks the surface area for the thermal (not just the spokes) against any voids areas that encroach into the thermal.
2015-09-07T16:47:36 < dongs> but thats an error, not anything you can "fix".
2015-09-07T16:48:10 < dongs> i think you better just set stuff to direct connect and forget it :)

2015-09-07T16:49:54 < __rob2> never had a problem doing it by hand before, but this has some bga bits on it..

2015-09-07T16:50:32 < dongs> i have a proper reflow oven
2015-09-07T16:50:37 < dongs> and I've done many 4L and some 6L boards in it
2015-09-07T16:50:41 < dongs> and i always direct connect
2015-09-07T16:50:47 < __rob2> ok, thats really good to know
2015-09-07T16:50:59 < dongs> but i duno how it would affect "ghetto" reflow oven.
2015-09-07T16:51:02 < dongs> probably not much.
2015-09-07T16:51:09 < __rob2> to be honest that is totally shit that altium has no algorithm to compensate for overlaps like that
2015-09-07T16:51:19 < dongs> heh heh
2015-09-07T16:51:24 < dongs> it does for regular planes
2015-09-07T16:51:27 < dongs> you can do dead copper removal
2015-09-07T16:51:32 < dongs> but not for split planes for some rasron
2015-09-07T16:51:33 < dongs> reason
2015-09-07T16:51:35 < __rob2> also get loads of isolated sliver errors which you then have to patch out one by one if you want it to build clean
2015-09-07T16:51:48 < dongs> sliver trash just disable that drc dude
2015-09-07T16:52:01 < __rob2> yea - have done :)
2015-09-07T16:52:23 < __rob2> still anooying they put errors in there that their own shit will cause every time

2015-09-07T20:50:16 < BorgCuba> hi, I am using newlib and calling fgetc(stdin) in my program. I also implemented _read and it seems like fgetc initiates a call to _read with len=1024. Whats the expected behaviour of read?

2015-09-07T20:53:36 < PaulFertser> BorgCuba: see e.g. http://www.embecosm.com/appnotes/ean9/ean9-howto-newlib-1.0.html
2015-09-07T20:55:47 < BorgCuba> PaulFertser, I read it. Seems like for that one specific device a '\n' is the only case returning < len bytes
2015-09-07T20:56:36 < BorgCuba> but why does fgetc result in read 1024 bytes?
2015-09-07T20:56:49 < Steffann> You need to set the stream to unbuffered maybe with setbuf ?
2015-09-07T20:56:49 < BorgCuba> nonblocking input?
2015-09-07T20:57:21 < Steffann> (or setvbuf)
2015-09-07T20:58:09 < jpa-> yeah, newlib buffers by default
2015-09-07T20:58:25 < jpa-> what is expected of _read is to read atleast 1 byte and return when it feels like returning
2015-09-07T20:58:56 < jpa-> on lunix it typically feels like returning after linefeed
2015-09-07T20:59:37 < BorgCuba> okay, then I will implement it like this
2015-09-07T21:17:32 -!- Lerg [~Lerg@188.226.45.254] has joined ##stm32
2015-09-07T21:19:15 < mtbg> well, in linux read() returns probably as soon as there is something available on fd and awaiting more data would block
2015-09-07T21:20:57 < mtbg> that buffering until linefeed is just a tty thing which is a property of 'canonical' tty mode
2015-09-07T21:22:04 < jpa-> actually in non-tty mode it probably returns only after full request amount is filled
2015-09-07T21:24:10 < mtbg> typical event-driven model with select/poll in main loop expects that if select/poll indicates something available on fd, then one subsequent read() on it will not block
2015-09-07T21:24:59 < jpa-> i wonder if that requires setting non-blocking mode
2015-09-07T21:25:54 < BorgCuba> I thought so too (block until len bytes are read).
2015-09-07T21:26:23 < mtbg> Under Linux, select() may report a socket file descriptor as "ready for reading", while nevertheless a subsequent read blocks.  This could for example happen when data has arrived but upon examination has  wrong  checksum  and  is  dis‐
2015-09-07T21:26:27 < mtbg>  carded.  There may be other circumstance in which a file descriptor is spuriously reported as ready.  Thus it may be safer to use O_NONBLOCK on sockets that shouled not block.
2015-09-07T21:27:05 < mtbg> unnecessary blocking would affect responsiveness
2015-09-07T21:31:10 < mtbg> file streams in C have also their own buffer
2015-09-07T21:32:10 < mtbg> so that for example it is possible to implement fgets without having to discard data from subsequent line and rewind file
2015-09-07T21:33:38 < mtbg> after that _read call from fgetc(), all of the bytes except first one are going to be appended to file buffer in libc
2015-09-07T21:34:23 < mtbg> and first one will be returned by fgetc
2015-09-07T21:34:43 < BorgCuba> same behaviour on my linux machine, blocks until '\r' is received
2015-09-07T21:35:08 < mtbg> since tty :>
2015-09-07T21:36:54 < BorgCuba> probably, this is what I get: http://pastebin.com/30zekKmH
2015-09-07T21:39:07 < mtbg> struct termios tty_opts; tcgetattr(0, &tty_opts); tty_opts.c_lflag &= ~ICANON; tcsetattr(0, TCSANOW, &tty_opts);
2015-09-07T21:39:17 < mtbg> and #include <termios.h>
2015-09-07T21:42:22 < BorgCuba> thank you mtbg
2015-09-07T21:48:33 < dekar> Is it correct that I can't run an STM32F429 in overdrive mode if I want to use USB at the same time? Also what's up with PLLSAI? According to the ST samples you can use the Serial Audio Interface PLL for USB as well.

2015-09-07T23:10:10 < mitrax> on a board with an STM32F4 i want to switch on/off some of the peripherals (SDRAM / SDCARD) when the cpu is asleep, i have a GPIO extender with very low consumption that i'd use to toggle them, should i use a high side driver with a P channel FET or will a low side driver with a N channel FET do?
2015-09-07T23:10:19 < mitrax> i'm guessing the N channel is it a bad idea since the SDRAM may power up through other pins set to a low state or something
2015-09-07T23:10:39 < mitrax> err is it a / IS a bad idea

2015-09-08T02:02:06 < Sync> it does not melt
2015-09-08T02:02:14 < Sync> it goes into solution
2015-09-08T02:02:55 < Sync> also diamond does not melt, it desintegrates at high temperatures into carbon
2015-09-08T02:03:14 < Sync> which in turn goes into solution

2015-09-08T03:36:58 < upgrdman> are there any benefits for a language that is interpreted instead of compiled?
2015-09-08T03:37:54 < zyp> in what sense? any language can be interpreted
2015-09-08T03:40:13 < upgrdman> well like python
2015-09-08T03:40:25 < upgrdman> why would you even *want* to be interpreted?
2015-09-08T03:40:41 < upgrdman> compiled is faster. JIT is a compromise.
2015-09-08T03:42:40 < zyp> flexibility
2015-09-08T03:43:12 < upgrdman> aside from cross-platform, what kind of flex?
2015-09-08T03:43:25 < zyp> dynamic typing
2015-09-08T03:43:37 < upgrdman> hmmm ok
2015-09-08T03:44:33 < zyp> in python, an identifier can point to anything, you don't know beforehand what type it would be and thus what to do about it
2015-09-08T03:48:02 < __rob2> python does compile to their python bytecode ahead of time

2015-09-08T03:48:27 < zyp> yes, but that's different
2015-09-08T03:51:50 < __rob2> upgrdman, pythons pretty handy when you want to develop something quickly
2015-09-08T03:52:07 < __rob2> recompiling can slow things down alot if you want to iterate fast
2015-09-08T03:53:54 < __rob2> one thing I found really handy was for quickly making an opengl viewport for something. I had a Qt Opengl viewport, where the draw function eval'd a python script
2015-09-08T03:54:18 < __rob2> so I could write the opengl in the script in realtime, as soon as I saved see the result
2015-09-08T03:55:33 < __rob2> couldn't really do that with c++ or something
2015-09-08T03:56:53 < zyp> sure you can
2015-09-08T03:58:52 < __rob2> you'd have to recompile each time
2015-09-08T04:05:43 < zyp> that's not fundamentally different from the python file being reparsed each time
2015-09-08T04:06:02 < __rob2> no, its not
2015-09-08T04:06:10 < __rob2> but it takes 100th of a second or whatever
2015-09-08T04:06:23 < __rob2> and I instantly see my camera move, my light change colour or whatever
2015-09-08T04:06:46 < __rob2> it doesn't have to recompile, relink and restart the process each time to see a small change
2015-09-08T04:07:20 < __rob2> was just a random example of where I found python pretty neat
2015-09-08T04:08:42 < zyp> idk, it wouldn't be very hard to make something that compiles a c++ file into a dynamic lib, links it into a running process, calls a function from it, and unlinks it again
2015-09-08T04:08:48 < zyp> which would be rather similar to eval-ing python
2015-09-08T04:09:00 < __rob2> no doubt itss possible
2015-09-08T04:09:10 < __rob2> but this took me an hour from nothing to the viewport I wanted
2015-09-08T04:09:52 < __rob2> just saying its fast to test something out in a fraction of the time
2015-09-08T04:11:13 < zyp> idk, making something to build and execute a function from a .so can't take that much longer than making something to eval python code
2015-09-08T04:11:18 < __rob2> I had to create 2 files, about 20 lines of python and I was ready to go in 10 minutes
2015-09-08T04:11:34 -!- Simon--_ is now known as Simon--
2015-09-08T04:12:04 < zyp> sounds about as long time as it'll take to write something using dlopen/dlsym/dlclose
2015-09-08T04:13:01 < upgrdman> __rob2, thanks. python was just a random example. im neither for or against. never coded in py
2015-09-08T04:13:02 < __rob2> aright
2015-09-08T04:13:18 < __rob2> well each to their own zyp
2015-09-08T04:13:28 < __rob2> I prototype in python
2015-09-08T04:14:11 < zyp> I'm not saying I don't use python, I'm just saying you could do something similar in C++
2015-09-08T04:14:28 < __rob2> no one is arguing possibilities, just utility and speed
2015-09-08T04:15:00 < zyp> the advantages of python is not in that you don't have to compile code before you can run it
2015-09-08T04:15:18 < __rob2> one other thing, the second you want to do something with your solution, you then need to link in some more libs, edit the make file etc.. etc..
2015-09-08T04:15:19 < zyp> well, actually, the interactive console is kinda there
2015-09-08T04:15:24 < __rob2> with the above, I just add an import numpy
2015-09-08T04:15:30 < __rob2> or whatever
2015-09-08T04:15:39 < __rob2> and I'm away ..
2015-09-08T04:16:16 < __rob2> its and advantage to me..
2015-09-08T04:16:58 < __rob2> if your writing algorithms, its nice to get a result quickly
2015-09-08T04:17:18 < __rob2> once I have it working, then I go write in c++
2015-09-08T04:17:19 < zyp> you're making it sound like compiling is slow
2015-09-08T04:17:34 < __rob2> if its 3 seconds
2015-09-08T04:17:45 < zyp> why would it be three seconds?
2015-09-08T04:17:53 < __rob2> thats about 2.9 seconds too long when I want to quickly iterate
2015-09-08T04:18:32 < __rob2> to be fair, I use visual studio :)
2015-09-08T04:19:18 < __rob2> it always at least 3 second, even for an empty main
2015-09-08T04:19:53 < upgrdman> > visual studio
2015-09-08T04:19:54 < upgrdman> fail
2015-09-08T04:20:02 < upgrdman> ;)
2015-09-08T04:20:08 < __rob2> dunno, as an ide is pretty awesome
2015-09-08T04:21:22 < __rob2> the profiler puts little fire icons by your broken algorithm
2015-09-08T04:21:25 < __rob2> if thats not a win I dont know what is
2015-09-08T04:22:08 < upgrdman> neat

2015-09-08T07:26:16 < emeb_mac> like that guy in Vietnam who was buying stuff for free from Mouser and reselling it at slightly lower prices back to US customers.
2015-09-08T07:26:23 < zyp> haha, no, I already mailed them
2015-09-08T07:26:27 < emeb_mac> because he'd hacked their website.
2015-09-08T07:27:03 < upgrdman> emeb_mac, link to story?
2015-09-08T07:27:22 < emeb_mac> upgrdman: 3rd hand info
2015-09-08T07:27:25 < emeb_mac> no linky
2015-09-08T07:27:48 < upgrdman> o
2015-09-08T07:32:01 < dongs> er
2015-09-08T07:32:09 < dongs> does stm mac need reference 25mhz clock
2015-09-08T07:32:10 < dongs> from phy?
2015-09-08T07:32:14 < dongs> "need"
2015-09-08T07:32:48 < emeb_mac> yes
2015-09-08T07:32:52 < dongs> hm
2015-09-08T07:32:55 < dongs> and if this phy doesnt have it?
2015-09-08T07:32:58 < emeb_mac> or 50MHz if RMII
2015-09-08T07:33:11 < dongs> http://www.ti.com/product/dp83848j has no 25mhz clcokout?
2015-09-08T07:34:38 < emeb_mac> I think zyp used that part before
2015-09-08T07:34:44 < zyp> dongs, for RMII there must be a common 50MHz clock between the MAC and the PHY, it varies who provides it
2015-09-08T07:34:50 < zyp> emeb_mac, no, I used the micrel part
2015-09-08T07:35:01 < emeb_mac> oh, right
2015-09-08T07:35:07 < dongs> zyp, yeah, soyou mean i can feed 50mhz into phy from stm32 then?
2015-09-08T07:35:10 < zyp> that one looks like the one that I got with my waveshare board
2015-09-08T07:35:20 < dongs> no wavesahre is C
2015-09-08T07:35:23 < dongs> the tqfp package
2015-09-08T07:35:28 < dongs> J is qfn and a lot cheaper
2015-09-08T07:35:32 < emeb_mac> I think that's the same one that ST uses on their devboards
2015-09-08T07:35:34 < zyp> IIRC waveshare board have a 50mhz oscillator that feeds both PHY and MAC
2015-09-08T07:35:43 < emeb_mac> check their UM ckt
2015-09-08T07:36:15 < zyp> while the micrel PHY I used makes 50MHz and feeds the MAC from the PHY
2015-09-08T07:36:20 < emeb_mac> zyp:  correct - I kanged the waveshare ckt - it taps the osc out to both the PHY and MCU
2015-09-08T07:36:49 < zyp> either way, you need to feed the MAC in the stm32 from somewhere
2015-09-08T07:37:03 < dongs> can I just use some timer output to do 50mhz?
2015-09-08T07:37:09 < dongs> or is that too hax
2015-09-08T07:37:44 < emeb_mac> might work, but if it's jittery that would hurt
2015-09-08T07:38:00 < dongs> so just stick a 50mhz xtal on it?
2015-09-08T07:38:03 < dongs> oscillator
2015-09-08T07:38:07 < emeb_mac> that's what I did
2015-09-08T07:39:28 < zyp> yeah
2015-09-08T07:40:56 < dongs> clock is ETH_MDC?
2015-09-08T07:41:25 < dongs> er seems no
2015-09-08T07:41:29 < dongs> i should probly read before asking dumb

2015-09-08T08:05:29 < upgrdman> xxxy is fine. xy is fine. xyx is not.
2015-09-08T08:07:51 < zyp> sure
2015-09-08T08:08:35 < zyp> but can't you just match on «xy» and invert the result?
2015-09-08T08:08:51 < zyp> «yx» I mean
2015-09-08T08:09:41 < upgrdman> makes sense. thanks.

2015-09-08T11:32:00 < dongs> ah/al or wahever
2015-09-08T11:32:14 < qyx_> not yet
2015-09-08T11:33:40 < dongs> qyx what makes you think it should be faster than uint32
2015-09-08T11:33:45 < dongs> its probably faster than uint8_t
2015-09-08T11:33:58 < dongs> the 'fast' classification probably only relates to same width
2015-09-08T11:34:09 < qyx_> because it is defined to be the fastest type of AT LEAST 8 bits
2015-09-08T11:34:19 < qyx_> so if 32bits is faster than 8  bits, it should be 32bits
2015-09-08T11:39:13 < dongs> If you don.t need a specific storage size, but want the data structure that allows the fastest access while having at least N bits (and among data structures with the same access speed, the smallest one), use one of these:
2015-09-08T11:44:41 < jpa-> qyx_: so what type does uint8_fast_t end up for you?
2015-09-08T11:44:45 < jpa-> sizeof etc.
2015-09-08T11:48:48 < qyx_> 8 bits
2015-09-08T11:49:02 < qyx_> using gcc

2015-09-08T14:46:49 < jpa-> yeah
2015-09-08T14:47:12 < jpa-> based on symptoms, we are suspecting some kind of damage to the voltage pumps or whatever common analog parts there are on the chip
2015-09-08T14:47:34 < jpa-> because we are seeing noise-like data corruption at random locations all over the chip, and the locations change after every erase
2015-09-08T14:48:06 < jpa-> i would expect the voltage pump stuff to be near the top, as that is where the power supply pins are

2015-09-08T16:44:37 < Laurenceb> whyyy
2015-09-08T16:44:41 < Ecco> ok, so supposedly "work" would be in a reflow oven

2015-09-08T17:17:32 < aandrew> lol
2015-09-08T17:17:41 < dongs> it was ~20 minute video or something
2015-09-08T17:17:49 < dongs> about through-hole connectors not being reflow-rated (duh)
2015-09-08T17:18:01 < dongs> but what made me permanently remove him from all my social media contacts is
2015-09-08T17:18:05 < dongs> the reason WHY he was reflowing it
2015-09-08T17:18:17 < dongs> he just found a random pcb in the trash
2015-09-08T17:18:24 < dongs> and put it into his toaster oven to reflow it
2015-09-08T17:18:26 < dongs> the end
2015-09-08T17:18:28 < dongs> like
2015-09-08T17:18:31 < Ecco> what?
2015-09-08T17:18:58 < aandrew> lol
2015-09-08T17:19:11 < aandrew> we were talking about his accent in the other chan
2015-09-08T17:19:33 < aandrew> I mentioned that the way he stresses his words always reminds me of how you might talk when holding in a massive shit
2015-09-08T17:19:37 < dongs> ecco, a very common activity with absolutely retarded people who have no clue, is to "reflow" video cards and shit that don't work, because one thinks that some of the balls on the CPU /etc didn't solder and heating it up again fixes it
2015-09-08T17:20:00 < aandrew> like he's trying to make his point but also distracted because his sphincter is about to let loose
2015-09-08T17:20:54 < dongs> ugh
2015-09-08T17:20:58 < dongs> just fuck that guy
2015-09-08T17:21:15 < dongs> and he just drones on and on about same shit over and over
2015-09-08T17:21:19 < dongs> like again teh reflow video
2015-09-08T17:21:25 < dongs> it could be tl;dr'd in like 30 seconds
2015-09-08T17:21:36 < dongs> "I'm a retard who didn't know through-hole connectors are not high-temp"
2015-09-08T17:22:11 < gxti_> he used to occasionally have interesting stuff but i gave up a year  ago
2015-09-08T17:22:28 < dongs> it looks all dumb shit

2015-09-08T17:28:13 < gxti_> nah it probably works sometimes
2015-09-08T17:28:16 < aandrew> no it's not a pure myth
2015-09-08T17:28:24 < aandrew> it works the odd time but only for specific problems
2015-09-08T17:28:31 < dongs> it has probly less than 1% chance of working
2015-09-08T17:28:34 < Ecco> ok :)
2015-09-08T17:28:40 < Ecco> And I guess 10% chance of frying your board?
2015-09-08T17:28:41 < aandrew> i.e. thermal expansion/contracting cracking the balls of the BGA due to poor thermal management
2015-09-08T17:28:42 < BrainDamage> early designs had shit thermal management, long term thermal stress warped the board and disconnected some pins
2015-09-08T17:28:46 < dongs> more like 100%
2015-09-08T17:29:06 < dongs> yeah i dont think this shit would matter in the last decade+
2015-09-08T17:29:12 < aandrew> the guys who light a tea candle and put it on their GPU are full of shit
2015-09-08T17:30:10 < BrainDamage> that's how they do annealing cycles in the semicond industry, a wooden stove and a charcoal grill

2015-09-08T18:14:34 < Laurenceb> oops
2015-09-08T18:14:47 < Laurenceb> wrong window lol
2015-09-08T18:15:01 < dongs> fucking terrorist
2015-09-08T18:15:05 < dongs> looks useless anyway.
2015-09-08T18:17:42 < Ecco> I've just read reviews of the 858D hot air gun
2015-09-08T18:17:55 < Ecco> Some people say it's nice, but other people say it broke off pretty quickly
2015-09-08T18:18:24 < Ecco> I wouldn't mind putting a bit more money into this purchase if I could get something more reliable
2015-09-08T18:18:29 < Ecco> would you guys recommend anything else?
2015-09-08T18:18:44 < dongs> aoyue968+ is decent all in one solder+hotair+forget wat else is in it
2015-09-08T18:19:26 < dongs> https://www.leopardimaging.com/LI-OV5640-MIPI-AF.html this place lists last 2 pins as AFVCC/GND.
2015-09-08T18:19:36 < dongs> of course thats for mipi interface, so half the shit is NC
2015-09-08T18:19:53 < dongs> but if thats the case, then there's missing bits for DVP 0..7 in china-pinout.
2015-09-08T18:19:53 < scrts_w> hmm, I only have OV5642 datasheet
2015-09-08T18:19:56 < karlp> I've "baked" a laptop back to life by powering it on and wrappign it in blankets,
2015-09-08T18:20:00 < dongs> datashete is not a problem
2015-09-08T18:20:08 < dongs> the .png is a combination of all chink docs
2015-09-08T18:20:11 < dongs> and they're all different
2015-09-08T18:20:12 < dongs> lolo
2015-09-08T18:20:15 < dongs> (that came with the module)
2015-09-08T18:20:20 < karlp> one of the interns at work baked her laptop mobo back to life too, there's a few models it was "the" way to fix them.
2015-09-08T18:20:21 < Ecco> karlp: haha
2015-09-08T18:20:51 < scrts_w> dongs: I am trying to catch... what's the issue? zano posted a piece of schematic that doesn't make sense?
2015-09-08T18:21:04 < dongs> scrts_w: no, im trying to interface with chinacam

2015-09-08T18:21:35 < scrts_w> which, in particular?
2015-09-08T18:21:36 < dongs> they're all 24 pin

2015-09-08T18:22:25 < scrts_w> the image with the pinout there
2015-09-08T18:22:27 < scrts_w> makes sense?
2015-09-08T18:23:00 < dongs> except it doesnt match J1 pinout

2015-09-08T18:23:21 < dongs> if Y0/Y1 are data0/1 then they're not present on the 'connector 24 pin description'
2015-09-08T18:23:30 < dongs> as you see there's no Y0/Y1 there
2015-09-08T18:23:34 < dongs> so I'd be missing 2 bits of data.
2015-09-08T18:23:38 < scrts_w> nope
2015-09-08T18:23:52 -!- Viper168_ is now known as Viper168
2015-09-08T18:23:53 < scrts_w> same stuff with OV490 we are using here in addition to OV10640
2015-09-08T18:24:05 < dongs> and what is the  "stuff"?
2015-09-08T18:24:13 < scrts_w> automotive cameras
2015-09-08T18:24:15 < dongs> does data start counting at 2 or something?
2015-09-08T18:24:23 < dongs> for 8 bit wide/
2015-09-08T18:24:33 < scrts_w> so we have 12 bits output, but for YUV we are using [11:4] only
2015-09-08T18:24:40 < dongs> yeah but this is not YUV
2015-09-08T18:24:40 < scrts_w> so it's 8bit interface YUV422
2015-09-08T18:24:47 < dongs> i'd be using DVP
2015-09-08T18:24:57 < scrts_w> DVP means parallel interface
2015-09-08T18:24:57 < dongs> the jpeg mode
2015-09-08T18:24:58 < dongs> like zano.
2015-09-08T18:24:59 < dongs> yes.
2015-09-08T18:25:05 < scrts_w> so you will have 8 bit output
2015-09-08T18:25:07 < scrts_w> on MSB bits
2015-09-08T18:25:11 < scrts_w> you dont need two LSBs

2015-09-08T19:27:16 < zyp> sure, but in what sense?

2015-09-08T19:30:19 < Ecco> And what exchange rate is applied?
2015-09-08T19:30:34 < Ecco> Boy my bank sucks…
2015-09-08T19:30:55 < zyp> standard visa rate including 1.75% exchange fee, but that's charged by visa, not the bank
2015-09-08T19:31:01 < Ecco> oh ok
2015-09-08T19:31:15 < Ecco> Well, I don't know *who* charges me, I just see there's a fee
2015-09-08T19:31:48 < zyp> exchange fee isn't listed separately, it's part of the exchange rate I get
2015-09-08T19:31:57 < Ecco> I see
2015-09-08T19:31:59 < zyp> so it's not something I'm concerned about
2015-09-08T19:32:25 < Ecco> Yeah, most exchanges work like this. They add a "spread" which is the difference between the exchange rate in one way and the other

2015-09-08T21:55:28 < Ecco> Possible
2015-09-08T21:56:24 < Ecco> I wonder why many of you guys seem to be so skeptical about "non-dirt-cheap tools"
2015-09-08T21:56:39 < Ecco> I mean, sure, when you buy higher-end stuff the company makes more profit out of you
2015-09-08T21:56:56 < Ecco> that doesn't mean that what you purchase is necessarily not better than a cheaper version
2015-09-08T21:57:26 < Ecco> Exemple : I've bought a set of chinese screwdrivers, and a similar set from AEG
2015-09-08T21:57:35 < Ecco> The chinese one was like $10, the AEG $20
2015-09-08T21:57:44 < Ecco> Thing is, the chinese tips broke after a coupe use
2015-09-08T21:57:54 < Sync> well why do you buy two chinese POS screwdrivers
2015-09-08T21:57:56 < Sync> AEG is TTI
2015-09-08T21:58:03 < Sync> headquatered in hongkong
2015-09-08T21:58:03 < Ecco> whereas the AEG one, even though I've been using them for like 2 years, are brand new
2015-09-08T21:58:37 < Sync> I think the point is that usually good equipment is a single investment
2015-09-08T21:58:44 < Sync> so it is not worth trying to cheap out there
2015-09-08T21:58:52 < Ecco> well, I couldn't agree more!
2015-09-08T21:59:05 < Ecco> Of course very often you don't need high-end gear
2015-09-08T21:59:16 < Ecco> And like I said, I'm not looking for gold-plated screwdrivers
2015-09-08T21:59:41 < Ecco> but purchasing some with a decent alloy (I think it contained Molybden FWIW) was actually a good investment

2015-09-08T22:02:08 < Sync> well, the point is they are brass so they don't mark watch parts
2015-09-08T22:02:22 < Sync> and gold so that they don't leave traces that could corrode
2015-09-08T22:02:26 < Ecco> oh, ok

2015-09-08T22:02:40 < Ecco> Makes sense for a watchmaker then I guess :)
2015-09-08T22:03:03 < decimad> Hey there... so I'm finding code like http://pastebin.com/vNa0j8dz literally anywhere, setting up a GPIO with the stm cube... But where the hell are the alternate function indices configured with stm cube? This tiny bit of information seems to be omitted everywhere I looked in the last half hour
2015-09-08T22:04:05 < Ecco> To be honest, I've never bothered to use Cube. I just read the datasheet and wrote my own code.
2015-09-08T22:04:19 < Ecco> Maybe a waste of time, but it was a great learning experience.
2015-09-08T22:04:43 < decimad> Yes, true that, I basically want to compare http://pastebin.com/jkfGDcWp with a version in cube-language
2015-09-08T22:04:59 < decimad> And I have no freaking clue about cube ;)
2015-09-08T22:05:09 < Ecco> WTF is that "using" directive?
2015-09-08T22:05:15 < decimad> type alias
2015-09-08T22:05:23 < decimad> the "new" typedef
2015-09-08T22:05:35 < Ecco> Too much C++ for me in there :)
2015-09-08T22:06:41 < decimad> it's just defining pins for signals and then activating all necessary ports and configures them as eth alternate funcs
2015-09-08T22:06:48 < Ecco> ok
2015-09-08T22:07:20 < decimad> but I need to set the eth alternate function... in these cube examples I only see them setting up the io, but not setting which alternate function they want
2015-09-08T22:07:29 < decimad> or I'm missing something between the lines
2015-09-08T22:07:47 < Ecco> GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP
2015-09-08T22:07:52 < Ecco> isn't that what it does?
2015-09-08T22:08:10 < decimad> well, but there are like 5 possible alternate functions for each pin
2015-09-08T22:08:26 < Ecco> yeah, isn't that what the "_PP" part do?
2015-09-08T22:08:37 < decimad> I guess it tells push&pull output
2015-09-08T22:08:39 < Ecco> (aren't there, maybe, GPIO_MODE_AF_SOMETHINGELSE?)
2015-09-08T22:08:55 < Ecco> Well that's what I thought, but that wouldn't make much sense for an AF…

2015-09-08T22:09:50 < decimad> Yeah, that got me confused back then too, but my alternate functions wouldnt work if I wouldn't configure it as an output... iirc... but that's not an issue currently
2015-09-08T22:10:11 < Ecco> HOnestly, I've no idea
2015-09-08T22:10:20 < Ecco> Maybe they don't need to set the AF because the default value suits them?
2015-09-08T22:10:22 < decimad> AF_PP doesnt say ETH or Timer or whatever... so I'm quite lost where they set this up

2015-09-08T22:23:59 < Ecco> I guess, in that case, that the default value suited then
2015-09-08T22:24:00 < decimad> but it does not seem to be necessary to call it in moste cases, it seems
2015-09-08T22:24:17 < decimad> yeah, I'll check for reset values
2015-09-08T22:24:52 < decimad> all reset values are 0x0, ie. AF0 for every gpio
2015-09-08T22:25:02 < Ecco> yes
2015-09-08T22:25:08 < Ecco> and maybe, in their case, they're using AF0?
2015-09-08T22:25:58 < decimad> well, on stm32f4 AF0 is system functions... like jtag interface and such... no peripherals
2015-09-08T22:26:40 < decimad> maybe it's handled differently on smaller mcus? hrmmm

2015-09-09T01:22:45 < yan_> i'm planning on creating a small bootloader to grab an image via a bluetooth ic for the stm32L1. is it as simple as flash_unlock()ing, then writing new firmware, then re-locking and resetting?
2015-09-09T01:23:48 < ds2> think you need to make sure you are flashing underneath yourself
2015-09-09T01:24:02 < yan_> ds2: the plan is to use the first 2-4k as a permanent bootloader
2015-09-09T01:24:14 < yan_> and make sure to write afterwards.. should also make linking easier
2015-09-09T01:24:36 < ds2> as long as you are in the same block that you are writing to
2015-09-09T01:24:45 < ds2> otherwise, you might have to move yourself to ram
2015-09-09T01:25:02 < yan_> same flash block? as in page?
2015-09-09T01:25:27 < ds2> donno the exact arrangement of the flash on that part
2015-09-09T01:25:40 < ds2> page is usually for erase size
2015-09-09T01:25:57 < ds2> by block I mean the group since the flash controller can take out the whole block

2015-09-09T03:48:23 < jadew> but most likely bigger shells which shattered
2015-09-09T03:48:29 < kakimir> jadew: some of them have been little animals

2015-09-09T08:39:21 < dongs> what do you need to test?
2015-09-09T08:39:26 < dongs> i can cut half of hte dildo off

2015-09-09T08:39:34 < dongs> i just copypasted nrf schematic/layout tho

2015-09-09T08:40:06 < zyp> I'm thinking about the rest of the circuit
2015-09-09T08:40:11 < dongs> ah rite
2015-09-09T08:41:11 < dongs> h,
2015-09-09T08:41:18 < dongs> zyp, if i have 4 timer channels right
2015-09-09T08:41:20 < dongs> on same timer
2015-09-09T08:41:26 < dongs> and I want to 'start" them at different times
2015-09-09T08:41:32 < dongs> do I just preload CCR or whatever then enable timer?
2015-09-09T08:41:40 < zyp> start?
2015-09-09T08:41:43 < dongs> yeah
2015-09-09T08:41:43 < dongs> like
2015-09-09T08:41:49 < dongs> i wanna drive ghettostepper
2015-09-09T08:41:59 < dongs> so its like 4 pulses slight ly offset
2015-09-09T08:42:07 < dongs> no speed control or anything just real dumb
2015-09-09T08:42:38 < zyp> uh, well, pulses have both length and offset
2015-09-09T08:42:41 < dongs> http://home.cogeco.ca/~rpaisley4/UnipolarWave.GIF
2015-09-09T08:42:46 < zyp> normally length is what you put into CCR
2015-09-09T08:42:48 < dongs> like this
2015-09-09T08:43:11 < dongs> any way to easily stagger it like that?

2015-09-09T08:46:49 < zyp> I don't think there's any way to do that in a simple way with only one timer
2015-09-09T08:46:56 < dongs> psh...
2015-09-09T08:49:50 < dongs> cant I 'start' each channel with a delay?

2015-09-09T10:36:15 < Ecco> Can Ethanol be used as a replacement?
2015-09-09T10:39:41 < zyp> more popular?

2015-09-09T10:41:02 < Ecco> Well, here you can buy 99% pure ethanol pretty much everywhere
2015-09-09T10:41:16 < Ecco> (note the remaining 1% will make you sick as fuck if you ever try to dring it though :-D)
2015-09-09T10:41:33 < Ecco> But litteraly everywhere, local grocery store, supermarkets, you name it
2015-09-09T10:42:03 < Ecco> Now I've looked for IPA, even at stuff like our local Home Depot
2015-09-09T10:42:08 < Ecco> Couldn't find any…
2015-09-09T10:42:47 < Ecco> Even Amazon doesn't sell any
2015-09-09T10:42:58 < PaulFertser> I think ethanol works nicely for cleaning PCBs.

2015-09-09T10:43:59 < Ecco> I just drowned the mobo in ethanol for like 10 minutes, brushed it with a soft toothbrush, and dryed it with a blowdryer
2015-09-09T10:44:02 < Ecco> worked like a charm

2015-09-09T11:32:27 < decimad> Hey, I asked already yesterday, but maybe you guys know... does the cube library somehow set up default alternate modes for all GPIOs in the startup code? In the source examples I see online, they only set up GPIOs to alternate mode, but don't specify which alternate mode to use, at least if I'm reading it correctly. Still they comment it with "Set peripheral unit X on GPIO Y"

2015-09-09T12:43:43 < PeterM> Ecco depends on the pitch and the ball count and the ball layout
2015-09-09T12:43:48 < Ecco> ok
2015-09-09T12:43:58 < Ecco> What are the general ways to do it?
2015-09-09T12:44:37 < PeterM> either there is unpopulated balls in the middle so you can route bigger traces through bigger vias for power, or the spacing allows room for via out
2015-09-09T12:46:00 < Ecco> So you can put vias straight inbetween balls?
2015-09-09T12:46:14 < Ecco> Wow, the drilling has to be pretty accurate I guess!

2015-09-09T12:46:44 < PeterM> yeah\
2015-09-09T12:47:10 < Ecco> Ok :-) Interesting. Thanks!
2015-09-09T12:47:38 < PeterM> google bga escape routing or bga breakout routing and look at images
2015-09-09T12:48:09 < Ecco> ok, "escape routing" is exactly what I was looking for

2015-09-09T12:48:22 < Ecco> So indeed, routing BGA seems like a nightmare :-D
2015-09-09T12:48:24 < PeterM> fanout also works
2015-09-09T12:48:31 < PeterM> not really
2015-09-09T12:48:47 < PeterM> its pretty easy, just requires decent fab
2015-09-09T12:48:53 < Ecco> hmm, I see
2015-09-09T12:49:02 < PeterM> the actual routing is copy+pasta
2015-09-09T12:49:22 < Ecco> Hmm, ok :)
2015-09-09T12:49:55 < Ecco> By the way, do you guys recommend any good fab that would do prototype runs (<5) in a decent time for a decent price?
2015-09-09T12:50:06 < Sync> PeterM: the isl55110ivz seems to be a nice driver
2015-09-09T12:50:07 < Ecco> I really like OSHPark, but shipping takes forever…

2015-09-09T12:52:04 < PeterM> the isl55110 is good driver but low side only
2015-09-09T12:52:23 < PeterM> i've had nothign but problems from oshpark
2015-09-09T12:52:30 < Ecco> Really?
2015-09-09T12:52:34 < PeterM> yeah
2015-09-09T12:52:44 < Ecco> Well, so far I ordered one PCB from them
2015-09-09T12:52:46 < dongs> oshpark quality is crap
2015-09-09T12:52:49 < Ecco> It was a simple one though
2015-09-09T12:52:52 < Ecco> It seemed OK
2015-09-09T12:53:02 < Ecco> And it was cheap
2015-09-09T12:53:06 < Ecco> and purple, which looks nice :)
2015-09-09T12:53:15 < Ecco> More seriously though, what would you recommend?
2015-09-09T12:53:59 < PeterM> pads/tracks over etched, vias missing drills, shitty board outline routing, gold plating failure, annular ring breakout
2015-09-09T12:54:10 < Ecco> :-S
2015-09-09T12:54:12 < PeterM> you name it, oshpark does it
2015-09-09T12:54:22 < Ecco> Hmm, vias missing drills is pretty bad
2015-09-09T12:54:48 < dongs> http://i.imgur.com/AQGrCGY.jpg my purple boards aare nice too
2015-09-09T12:55:06 < dongs> http://i.imgur.com/Ds5jDHW.jpg but not my camera skillz
2015-09-09T12:55:09 < PeterM> *and* ahve real silkscreen
2015-09-09T12:55:14 < Ecco> Indeed
2015-09-09T12:55:27 < Ecco> dongs: Who built those PCBs?
2015-09-09T12:55:38 < PeterM> fuck off dongls, you should have glorious sharp nippon camera ninja skills
2015-09-09T12:55:48 < dongs> Ecco: me
2015-09-09T12:55:52 < Ecco> My needs ATM are very simple, 2 layers, decent minimal spacing (10mil)
2015-09-09T12:56:02 < Ecco> dongs: How?
2015-09-09T12:56:24 < Ecco> Do you make PCBs for other people?
2015-09-09T12:56:37 < dongs> yes but they're not cheap + my time is not checap
2015-09-09T12:56:39 < dongs> so I prefer not to do it
2015-09-09T12:56:40 < Ecco> ok :)
2015-09-09T12:56:48 < Ecco> Cheap is an important factor for me here
2015-09-09T12:57:05 < Ecco> I don't want absolute crap, but I will probably need to iterate quite a lot
2015-09-09T12:57:09 < Ecco> So if OSHPark is not so good
2015-09-09T12:57:16 < Ecco> What would you guys recommend, then?
2015-09-09T12:57:22 < dongs> oshpark will be OK if '10mil' is your 'decent spacing'
2015-09-09T12:57:22 < Sync> well PeterM I currently use ir2101 which are fine
2015-09-09T12:57:32 < dongs> like 95% of the shit i do is 5/5 spacing
2015-09-09T12:57:38 < Ecco> Yes, I'm not doing anything fancy
2015-09-09T12:58:01 < Ecco> I guess the most difficult thing needed are the UFQFN48 pads
2015-09-09T12:58:10 < PeterM> sync ir2101 is a completely different type of part
2015-09-09T12:58:13 < Sync> but the next generation™ hardware will use coolmos c7 so I suspect that I need faster gatedrive
2015-09-09T12:58:41 < Sync> yeah
2015-09-09T12:59:03 < Sync> I just realized that it is not HVCMOS
2015-09-09T12:59:06 < Sync> just had a skim read
2015-09-09T13:00:10 < PeterM> IR do best HV HS drivers, no doubt about it
2015-09-09T13:02:47 < PeterM> i just wish their drivers came with thermal pads because their higher power higher pseed drivers can get QUITE hot in SOIC

2015-09-09T13:40:05 < PeterM> for boards that i need to be made in low quantity i use goldpheonixpcb or pcbcart
2015-09-09T13:40:49 < PeterM> enig is really nice for bga and qfn but otehr than that, you can pass
2015-09-09T13:41:29 < PeterM> dongs wut
2015-09-09T13:42:01 < dongs> PeterM: tell that to this retard jap who ordered 6layer board with HASL
2015-09-09T13:42:03 < dongs> with hasl
2015-09-09T13:42:13 < dongs> and like ~6 bga chips on it
2015-09-09T13:42:50 < Ecco> I have a single UFQFN48 chip to solder. Would that require ENIG, or can HASL do the trick?
2015-09-09T13:43:22 < PeterM> hasl is fine for prototype qfn, you can just rework the shti till it works
2015-09-09T13:43:33 < Ecco> Indeed :)
2015-09-09T13:43:42 < PeterM> HASL is OK for BGA is the pads a re super flat, but they probably arent
2015-09-09T13:43:49 < dongs> they arent
2015-09-09T13:43:54 < dongs> its the usual bumpy trash hasl
2015-09-09T13:44:01 < dongs> but i think the jap is nutso anyway
2015-09-09T13:44:07 < dongs> i think hes just using hot air
2015-09-09T13:44:10 < Ecco> ok, thanks!
2015-09-09T13:44:14 < dongs> and hoping there's enough solder on pads + bga
2015-09-09T13:44:16 < dongs> to maybe stick
2015-09-09T13:45:59 < Ecco> pcbcart is very expensive in my case (minimal quantity, 8cmx8cm 2layers -> $62)

2015-09-09T19:18:51 < dongs> Indoor follow me modes and hold position will come later through image processing. You are quite correct. The plan is to offer better obstacle avoidance when flying forwards such as intelligently steer around objects immediately in front, once again all by being able to process the video feed.
2015-09-09T19:18:57 < dongs> We may even release a module to replace the RGB display with a sole purpose of special camera and image handling for really cool features.
2015-09-09T19:19:00 < dongs> ha ha ha
2015-09-09T19:19:02 < dongs> god damn wehre does this guy get off
2015-09-09T19:20:43 < upgrdman_> is there any time, with an mcu, where you wouldnt need to make a global as volatile? just when the shared variable is never accessed in an ISR?
2015-09-09T19:20:52 < dongs> er
2015-09-09T19:20:55 < dongs> like always?
2015-09-09T19:21:09 < dongs> i dont think i have any projects with volatile globals
2015-09-09T19:21:23 < dongs> if you got shit you're accessing from that many places, youre doing somethin wrong anyway.
2015-09-09T19:21:52 < upgrdman_> ? shouldn't data that can be modified by an ISR be marked global so the compiler doesn't optimize out a read or write?
2015-09-09T19:22:11 < mitrax> dongs: gaaah he put a UF4007 instead of a schottky no wonder... now he put a B250 and it works ... thanks :)
2015-09-09T19:22:36 < upgrdman_> *marked volatile
2015-09-09T19:25:06 < dongs> cool
2015-09-09T19:26:55 < upgrdman_> dongs, weird. maybe it's a gcc thing? seems like you would always want to make a variable that could change "behind the scenes" as volatile since the compiler has no way to keep track of it
2015-09-09T19:27:41 < dongs> upgrdman_:  iduno, i generally don't  touch a lot of stuff from ISR, and if i do its registers or some other hardware stuff
2015-09-09T19:27:56 < dongs> i cant really think of any examples where I had to deal with normal vs volatile var
2015-09-09T19:28:14 < dongs> if I have to pass data i usually have a rtos and queues/messages going on.
2015-09-09T19:28:36 < upgrdman_> well, like the ADC. if you read values in the ISR, how do you share those values with code that will use it?
2015-09-09T19:28:46 < upgrdman_> or do you just use dma for that
2015-09-09T19:28:53 < dongs> dma into buffer

2015-09-09T20:24:16 < Bundestrojaner1> good evening
2015-09-09T20:24:43 -!- dekar [~dekar@46.243.86.234] has quit [Quit: This computer has gone to sleep]
2015-09-09T20:26:27 < ReadError> <dongs> you cant spell holocaust without lol
2015-09-09T20:27:29 < Bundestrojaner1> is there any tutorial for i2c on the STM32F0-discovery?
2015-09-09T20:27:30 < Bundestrojaner1> i seached google but without any succes...
2015-09-09T20:27:30 < Bundestrojaner1> i know what i2c is and used it on ATMegas, but i have no idea how to use it on stm32
2015-09-09T20:27:44 < dongs> have you looked at stdperiphlib?
2015-09-09T20:27:52 < dongs> it comes with 'Examples' folder
2015-09-09T20:27:59 < dongs> and has 2-3 different I2C usage scenarios
2015-09-09T20:28:08 < dongs> or failing that, you can always just bitbang it arduino-style.
2015-09-09T20:28:33 < Bundestrojaner1> dongs: yes, i looked at the eeprom-example because it's what i want to do
2015-09-09T20:29:56 < rewolff2> Re: bootloader: Wait. Now I remember.
2015-09-09T20:29:56 < rewolff2> IF bootmode = boot-to-user-code AND flash-is-empty THEN jump-to-bootloader-anyway
2015-09-09T20:29:56 < rewolff2> and the "flash-is-empty" test is simplified to  one 32-bit-location being empty (0xffff...)
2015-09-09T20:30:30 < rewolff2> Since 3 minutes, I have I2C working on my F042 board. :-)
2015-09-09T20:30:31 < dongs> probly just checks 1st byte of vector table rite
2015-09-09T20:30:45 < rewolff2> That would be "too accurate".

2015-09-09T20:31:04 < rewolff2> IIRC there was a way that this could mis-fire.
2015-09-09T20:31:26 < rewolff2> But "close". so you have to set up the situation where it would go wrong.
2015-09-09T20:31:49 < rewolff2> maybe the "first location of vector table" is indeed right. You'd almost never want stack to start at 0xffffffff
2015-09-09T20:35:02 < Bundestrojaner1> dongs: those example seem a bit complex for understanding how to use i2c
2015-09-09T20:36:01 < zyp> rewolff2, it's completely impossible for stack on stm32 to be at 0xffffffff, the top memory region is reserved so there will never be memory mapped there
2015-09-09T20:36:29 < zyp> that said, the stack vector is not strictly required, so you might want to check the reset vector instead
2015-09-09T20:37:01 < rewolff2> Right. But SUPPOSE you want to start your code without stack, ... without calling anything you memcheck your RAM and THEN initialize your stack pointer?
2015-09-09T20:37:24 < rewolff2> THEN of course you SHOULD NOT leave your vectortable[0] at 0xffffffff ... You know that now...
2015-09-09T20:37:39 < zyp> http://cgit.jvnv.net/arcin/tree/bootloader.cpp#n267 <- here's what I do in my bootloader
2015-09-09T20:38:35 < dongs> hacker
2015-09-09T20:39:18 < rewolff2> yeah. So ST does something similar in hardware. in some bootloaders.
2015-09-09T20:39:33 < zyp> NXP stuff is even more elaborate and uses one of the spare unused vectors for a checksum
2015-09-09T20:41:44 < rewolff2> (IMHO, ALWAYS jumping to bootloader would've been a good idea. Then bootloader polls two pins (boot0, boot1), stuffs it into a register (SYSCFG or something), and then jumps somewhere (pc := mem[4]) . Then... after boot you can use boot0 and boot1 again. Not for everything, but e.g. pulldown-and-led is possible.)
2015-09-09T20:42:51 -!- grummund [~user@unaffiliated/grummund] has quit [Ping timeout: 260 seconds]
2015-09-09T20:42:52 < rewolff2> The drawback is a few cycles longer boot time until first user-instruction is run. Which /I/ consider not so much of a problem.
2015-09-09T20:43:21 < rewolff2> (it matters if you deep-sleep the CPU and still need fast response).
2015-09-09T20:43:58 < zyp> what exactly are you arguing?
2015-09-09T20:44:26 < rewolff2> stm32 could've been better. :-)
2015-09-09T20:44:44 < dongs> Then... after boot you can use boot0 and boot1 again. Not for everything, but e.g. pulldown-and-led is possible.)
2015-09-09T20:44:47 < dongs> errr
2015-09-09T20:44:48 < dongs> you can already do this
2015-09-09T20:44:49 < zyp> boot1 is a normal gpio on the parts where it exists, so it can already be used normally after boot anyway
2015-09-09T20:44:55 < dongs> and I do this on a few of my boards
2015-09-09T20:44:57 < rewolff2> yes. But boot0 is not.
2015-09-09T20:44:59 < dongs> wat are you talkin about
2015-09-09T20:45:13 < zyp> rewolff2, no, but that has no relation to whether the bootloader always runs or not
2015-09-09T20:45:17 < dongs> one of bootpins is even gone on some newer Fx series
2015-09-09T20:45:24 < dongs> stuck into option bytes
2015-09-09T20:45:26 < dongs> boot1 maybe?
2015-09-09T20:45:30 < zyp> yeah
2015-09-09T20:46:02 < zyp> I always just tie boot0 low, and then boot1 doesn't matter either way
2015-09-09T20:46:28 < zyp> if I need a bootloader, I might as well write my own
2015-09-09T20:46:39 < rewolff2> If you don't do it in hardware, and just always run the rom-code, boot0 and boot1 functionality comes automatic at the expense of a few clocks at boot, but the advantage of both being GPIO.
2015-09-09T20:47:01 < dongs> shrugging furiously
2015-09-09T20:47:19 < rewolff2> Sure. Go ahead and shrug. :-)
2015-09-09T20:47:31 < zyp> rewolff2, but what would the advantage be?
2015-09-09T20:47:36 < rewolff2> My 14-pin AVR has the same number of usable IO as the 20-pin STM32.
2015-09-09T20:48:06 < zyp> rewolff2, the LPC family does what you're proposing and I hate it
2015-09-09T20:48:13 < rewolff2> So Atmel is "better" at making "everything else is GPIO".
2015-09-09T20:48:25 < rewolff2> OK. explain me why. I want to know.
2015-09-09T20:49:45 < dongs> lols, jewpad pro is 13"
2015-09-09T20:49:52 < dongs> stupid apple
2015-09-09T20:49:59 < zyp> because I don't want vendor code to dick around before passing me control
2015-09-09T20:50:07 < dongs> at a price of a ~decent laptop that would be ablt ot do 100x more
2015-09-09T20:51:25 < decimad> oh, I'm seeing only now there's a bootloader in there... can you reclaim that memory? :)
2015-09-09T20:51:36 < upgrdman_> Bundestrojaner1, here some code i wrote that does i2c on an f0. it's not an example of great code, but it works:

2015-09-09T20:52:03 < dongs> indent -kr motherfucker
2015-09-09T20:52:08 < Bundestrojaner1> upgrdman_: thx!
2015-09-09T20:53:15 < upgrdman_> sure
2015-09-09T20:53:32 < upgrdman_> dongs, ? whats -kr? spaces instead of tabs?
2015-09-09T20:53:42 < dongs> k&r style
2015-09-09T20:53:44 < jubatus> man indent motherfucker
2015-09-09T20:54:21 < dongs> i think im using something like -kr -nut -l400
2015-09-09T20:55:00 < dongs> upgrdman_: 4 char indent, and overall ~nice style with spaces between operators and stuff.
2015-09-09T20:55:03 < zyp> rewolff2, also, you're full of shit
2015-09-09T20:55:04 < upgrdman_> i wish github had a way to render tabs as four spaces
2015-09-09T20:55:13 < rewolff2> Thanks.
2015-09-09T20:55:15 < dongs> upgrdman_: it does, by not using htem
2015-09-09T20:55:39 < dongs> <someapplefag> The future of TV is apps
2015-09-09T20:55:43 < zyp> rewolff2, I just checked, the 20-pin stm32 has 15 gpio pins, good luck having more usable gpios on a 14-pin avr
2015-09-09T20:55:50 < dongs> lol
2015-09-09T20:55:52 < dongs> ownt
2015-09-09T20:56:20 < zyp> the five remaining pins are boot0, nrst, vdda, vdd and vss
2015-09-09T20:56:45 < dongs> you should replace nrst with a gpio pin too
2015-09-09T20:56:46 < rewolff2> Well... in my case I2C and SPI are subtracted. On AVR only once, because there is overlap, and on STM they are separate. In other cases that might be an advantage.
2015-09-09T20:56:51 < dongs> just have a task that checks it periodically
2015-09-09T20:56:55 < dongs> and reboot if it changes
2015-09-09T20:56:56 < dongs> !!!!
2015-09-09T20:57:51 < upgrdman_> OH FUCK YES! ?ts=4 appended to any github url does the trick!
2015-09-09T20:57:57 < dongs> cool
2015-09-09T20:58:03 < dongs> that sounds like vim thing.
2015-09-09T20:58:04 < upgrdman_> much less ugly now:

2015-09-09T20:59:50 < zyp> rewolff2, uh, what?
2015-09-09T21:00:42 < rewolff2> Project: SPI / I2C slave (one at a time, not both). Then: AVR has 7 usable IO left. and STM320xxF has also about 7 left.
2015-09-09T21:01:13 < decimad> you can control the volume with the RC!
2015-09-09T21:04:02 < decimad> Icons with shadows! O.O
2015-09-09T21:04:14 < Steffann> wtf are you talking about?
2015-09-09T21:04:17 < rewolff2> P.S.: I don't like "blocking" my debug-port by using the debug pins. So STM has extra: VSSA, BOOT0, SWCLK, SWDAT, and two for I2C that were shared with SPI on AVR. (both have VDD, VSS, nRST)
2015-09-09T21:04:21 < Steffann> oh apple talk crap decimad?
2015-09-09T21:04:26 < decimad> I'm talking about the apple bullshit

2015-09-09T21:08:22 < zyp> rewolff2, well, you're making a pretty unfair comparison, both on this point, and on the i2c/spi sharing point, and the avr still doesn't have more free gpio

2015-09-09T21:09:33 < rewolff2> I expected STM32 to have more than the seven free IO of AVR, but, with my "restrictions", it still had only seven, just like the AVR.

2015-09-09T21:10:33 < zyp> well, sure, your silly restrictions is wasting four pins
2015-09-09T21:11:20 < rewolff2> On AVR, ISP works when you pull on "reset". ON STM if you reprogram SWD, you need to assert RESET to get the chip to listen again. And the STLINK modules from china don't have the RESET pin wired on the F103 where the STLINK on the Discovery boards have it. So you can't get your chip to reprogram if you have a bug in there somewhere.....
2015-09-09T21:11:59 < zyp> so don't buy shitty stlink modules from china.
2015-09-09T21:12:59 < rewolff2> Sounds like a plan.
2015-09-09T21:13:45 < emeb> zyp: interesting development - updated my BMP firmware to work with F7, but now F3 is broken.

2015-09-09T22:15:32 < zyp> that's an unsupported device id
2015-09-09T22:15:35 < zyp> which part is this?
2015-09-09T22:16:09 < emeb> STM32F302C8T6
2015-09-09T22:16:16 < emeb> rather new
2015-09-09T22:16:41 < zyp> yeah, so it were never supported and just happened to work before due to accident, I guess
2015-09-09T22:16:48 < emeb> I see
2015-09-09T22:17:02 < zyp> you can probably just add it in stm32f1.c, around line 137 somewhere
2015-09-09T22:17:09 < emeb> I'll look
2015-09-09T22:22:43 < emeb> added 	case 0x439:  /* STM32F302C8 */
2015-09-09T22:23:05 < emeb> rebuilt, reflashed bmp and now it works
2015-09-09T22:23:10 < emeb> \o/
2015-09-09T22:23:14 < emeb> thx for help
2015-09-09T22:23:36 < Tectu> zyp, master of being helpful
2015-09-09T22:23:40 < emeb> word
2015-09-09T22:23:59 < emeb> should probably push that. how to?

2015-09-09T22:45:17 < mervaka> reet on
2015-09-09T22:46:03 < mervaka> yeah I've been in that situation these last few days, feel guilty asking blatantly busy people :/
2015-09-09T22:46:18 < mervaka> who somehow still find the time to help
2015-09-09T22:46:46 < mervaka> ended up figuring it out myself, a weird SPI peripheral problem
2015-09-09T22:47:22 < mervaka> reference manual states that communication musn't be taking place when you change CPOL/CPHA/BR etc
2015-09-09T22:47:52 < mervaka> turns out i needed to clear SPE first, else i get some strange behaviour
2015-09-09T22:48:38 < mervaka> where once reconfigured, the first byte sent is prefixed with one or two bytes of garbage, and the OVR flag is raised
2015-09-09T22:48:54 < mervaka> presumably because it tried to receive those extra bytes too
2015-09-09T22:49:08 < mervaka> in fact i think it's just one byte
2015-09-09T22:49:16 < mervaka> and i only saw 7 bits :s
2015-09-09T22:50:00 < mervaka> anyway, resolved now.
2015-09-09T22:53:52 < emeb> mervaka: how goes things in high-end mixer land?
2015-09-09T22:54:08 < mervaka> steep
2015-09-09T22:54:13 < mervaka> lots of work on
2015-09-09T22:54:20 < emeb> that's a good thing!
2015-09-09T22:54:25 < mervaka> and running out of SRAM
2015-09-09T22:54:27 < mervaka> a lot
2015-09-09T22:54:37 < bvernoux> merkit it is the same for lot of peripheral configuration you shall NEVER reconfigure them during rx or tx
2015-09-09T22:54:45 < emeb> yell at the hardware designers to give you more SRAM!
2015-09-09T22:54:59 < mervaka> going up from a 4k screen buffer to a new screen that requires 18k
2015-09-09T22:55:08 < emeb> ouch
2015-09-09T22:55:12 < mervaka> double the bpp, larger screen res
2015-09-09T22:55:14 < zyp> mervaka, oh, that sounds like the 12 bit SPI transfers I saw once
2015-09-09T22:55:21 < bvernoux> mervaka, the problem is datasheet does not explain the internal links between some registers with others ;)
2015-09-09T22:55:43 < mervaka> the problem is the datasheet said it was okay, when it's blatantly not.
2015-09-09T22:55:50 < bvernoux> mervaka, like settings an option on reg0 will be applied & effective only when you set reg4 ...
2015-09-09T22:56:11 < mervaka> for a few days i took their word as gospel
2015-09-09T22:56:18 < zyp> bvernoux, blame shitty spi slave designers
2015-09-09T22:56:27 < mervaka> this is a master :/
2015-09-09T22:56:31 < bvernoux> mervaka, datasheet only cover standard usage ;) (and never on fly reconfiguration)
2015-09-09T22:56:32  * emeb has written datasheets. doesn't trust 'em. :)

2015-09-09T22:56:49 < mervaka> yeah, on-the-fly reconfig is a pain :/
2015-09-09T22:57:01 < zyp> mervaka, of course, but the slave is the reason I needed to reconfig
2015-09-09T22:57:05 < mervaka> but surely any shared SPI bus may have to do that
2015-09-09T22:57:12 < bvernoux> it always fail for 90% of driver if you want to do on-the-fly reconfig ;)
2015-09-09T22:57:36 < mervaka> i don't mind having to turn it off to reconfig
2015-09-09T22:57:38 < zyp> because this shitty slave I was interfacing with had different CPHA for read and write
2015-09-09T22:57:45 < mervaka> i just wish the fucking documentation was correct D:
2015-09-09T22:57:54 < mervaka> wtf zyp
2015-09-09T22:57:59 < mervaka> oh
2015-09-09T22:58:13 < zyp> so I had to change CPHA in the middle of transfer, when transitioning from writing the command to reading the response
2015-09-09T22:58:21 < bvernoux> mervaka, yes documentation are not always tested and it's very rare they speak about use case ;)
2015-09-09T22:58:23 < mervaka> what the actual fuck
2015-09-09T22:58:38 < mervaka> zyp: not pol?
2015-09-09T22:58:47 < bvernoux> zyp, and it fail I imagine ?
2015-09-09T22:58:48 < mervaka> i could almost understand that
2015-09-09T22:59:13 < bvernoux> zyp, solution is to do it by "hand" with bit banging sometimes ;)
2015-09-09T22:59:17 < mervaka> in my use case, screen and flash memory share an SPI
2015-09-09T22:59:35 < zyp> no, CPOL wouldn't make sense, that would risk introducing extra clocks or something
2015-09-09T22:59:50 < zyp> the CPHA rationale is simple enough
2015-09-09T22:59:57 < mervaka> bvernoux: or if you're using NXP parts, use SGPIO?
2015-09-09T22:59:57 < bvernoux> zyp, for STM32 I2C is so bad I do all with bit banging like that all work fine (even if we loose DMA and other cool stuff ... which are buggy anyway )
2015-09-09T23:00:01 < zyp> MISO is clocked on first edge, MOSI is clocked on second edge
2015-09-09T23:00:05 < zyp> or other way around
2015-09-09T23:00:28 < mervaka> oh is that to account for some sort of propagation delay?
2015-09-09T23:00:31 < bvernoux> mervaka, yes SGPIO is powerfull but so complex for nothing ;)
2015-09-09T23:00:36 < zyp> mervaka, idk, maybe
2015-09-09T23:00:38 < zyp> still dumb

2015-09-09T23:01:59 < mervaka> i haven't touched SCT myself

2015-09-09T23:02:05 < mervaka> haha
2015-09-09T23:02:13 < mervaka> always in ST world, me
2015-09-09T23:02:22 < zyp> same
2015-09-09T23:02:26 < mervaka> at least, when i'm dealing with lowest levels
2015-09-09T23:02:47 < mervaka> my time in NXP world is limited to far abstracted code and bit banging SPI
2015-09-09T23:02:53 < zyp> every time I try doing something with an LPC chip, I just get annoyed and give up
2015-09-09T23:03:00 < mervaka> heh
2015-09-09T23:03:15 < mervaka> it's not that bad, the documentation is just even more terrible than ST's
2015-09-09T23:03:21 < mervaka> well
2015-09-09T23:03:21 < bvernoux> mervaka, main problem with SGPIO it will be so nice to have up to 24 bits in // ;)
2015-09-09T23:03:29 < mervaka> bvernoux: it would
2015-09-09T23:03:44 < bvernoux> to drive big ADC/DAC
2015-09-09T23:03:53 < mervaka> that said, i think a colleague found fundamental problems with NSP's USB stack
2015-09-09T23:04:04 < mervaka> NXP*
2015-09-09T23:04:04 < bvernoux> as today it's very limited mainly 8bits (or 10bits with hack)
2015-09-09T23:04:20 < bvernoux> mervaka, ha which problem ?
2015-09-09T23:04:33 < mervaka> can't remember the exact details
2015-09-09T23:04:37 < bvernoux> mervaka, we use it in airspy since lot of time with no problem at all
2015-09-09T23:04:41 < mervaka> but we were using the 4300 family
2015-09-09T23:04:52 < mervaka> 4357
2015-09-09T23:04:54 < bvernoux> mervaka, with hard realtime streaming at 40MB/s
2015-09-09T23:05:00 < mervaka> mmm
2015-09-09T23:05:08 < mervaka> oh wait, i think i remember
2015-09-09T23:05:08 < bvernoux> it's the only one MCU to do that
2015-09-09T23:05:15 < mervaka> it's to do with how it works as a host
2015-09-09T23:05:16 < bvernoux> USB0 of course
2015-09-09T23:05:28 < bvernoux> ha ok I have never tested host mode
2015-09-09T23:05:38 < mervaka> i think if you try to host a USB mass storage device
2015-09-09T23:05:45 < mervaka> and the device NAKs
2015-09-09T23:05:53 < mervaka> it will immediately retry
2015-09-09T23:05:56 < mervaka> again and again
2015-09-09T23:05:58 < mervaka> and flood the key
2015-09-09T23:06:07 < mervaka> i believe that's the flaw
2015-09-09T23:06:13 < mervaka> no delay before retransmit
2015-09-09T23:06:24 < mervaka> and the key's NAK counter just goes to shit
2015-09-09T23:06:35 < zyp> key?
2015-09-09T23:06:41 < mervaka> usb mass storage device
2015-09-09T23:06:42 < mervaka> sorry
2015-09-09T23:06:47 < mervaka> my terminology swapped
2015-09-09T23:07:01 < zyp> what NAK counter?
2015-09-09T23:07:26 < mervaka> inside the usb storage device
2015-09-09T23:07:38 < zyp> uh, why would there be a NAK counter there?
2015-09-09T23:07:39 < mervaka> i think that may have been an assumption, i'm not sure

2015-09-09T23:08:06 < mervaka> but in manually delaying the retries, he fixed the problem
2015-09-09T23:08:07 < bvernoux> UMS is probably buggy ;)
2015-09-09T23:08:10 < zyp> uh, pretty sure there's no NAK counter
2015-09-09T23:08:24 < bvernoux> anyway UMS have lot of hint to work with different slave ...

2015-09-10T01:23:46 < hjf_> i've checked the circuit. all power l ines are connected. all decoupling caps are present
2015-09-10T01:24:28 < hjf_> the problem is erratic because of the 1117-3.3V regulator. SOMETIMES it works cause the reg gives "a little less" than 3.3V, but sometimes it gives 3.3V and the STM32 refuses to boot
2015-09-10T01:24:39 < hjf_> though, once booted, it works at 3.4V fine

2015-09-10T03:36:35 < dongs> not probably, no doubt

2015-09-10T03:38:48 < dongs> ikr
2015-09-10T03:39:13 < dongs> even sp3 pen is $50
2015-09-10T03:39:18 < dongs> and it has bluetooth and pressure sensitivty
2015-09-10T03:39:50 < dongs> if youre an artfag
2015-09-10T03:40:22 < dongs> it does

2015-09-10T03:40:34 < dongs> i duno if apple trash has pressure
2015-09-10T03:40:38 < dongs> bluetooth is for pressure
2015-09-10T03:40:44 < dongs> ntrig gets it contactless x,y
2015-09-10T03:40:49 < dongs> but if you wanna measure pressure then you need to pair it.
2015-09-10T03:41:31 < dongs> duno go google wabout apple one, i havent seen it

2015-09-10T04:22:56 < dongs> like my current S6 is slippery as fuck without case
2015-09-10T04:23:11 < dongs> so sticking some rubber bumper case over it at least helps that

2015-09-10T06:44:24 < englishman> theres a stop thats further on
2015-09-10T06:44:30 < englishman> this is a trust exercise
2015-09-10T06:45:23 < dongs> it sounds like the ultimate hoax until you try it. Instructions are simple: just push hard on the kickstand until it snaps and sounds like it's broken. The end result makes the kickstand loose and adjustable, and you can snap it back into the regular positions without breaking it.

2015-09-10T07:36:07 < reportingsjr> Hi, I'm trying to program an STM32F100 by using an stm32f100 discovery VL board as a programmer and I am not sure exactly what needs to be done.
2015-09-10T07:36:09 < dongs> Usually ships within 9 to 11 days.
2015-09-10T07:36:42 < dongs> reportingsjr: disconnect STLink on -discovery from the chip on it (there's jumpers). connect SWDCLK, SWDIO to your new board. connect common gnd between them. program.
2015-09-10T07:37:01 < reportingsjr> dongs: ok, I have that, I don't need to connect the reset pin?
2015-09-10T07:37:10 < dongs> not really
2015-09-10T07:37:12 < dongs> you can still reset via swd
2015-09-10T07:37:17 < ds2> and make sure it is the same voltage level
2015-09-10T07:37:19 < dongs> if stuff is badly broken you can hold reset on your board while connecting
2015-09-10T07:37:23 < ds2> IIRC, discovery units cannot sense voltage
2015-09-10T07:37:29 < reportingsjr> ds2: I noticed that
2015-09-10T07:37:33 < dongs> well, i presume he's at 3.3V or wahtever anyway
2015-09-10T07:37:47 < reportingsjr> so the issue I'm having is that I'm using texane st-link and gdb to program this
2015-09-10T07:37:58 < dongs> isnt that old as fuck
2015-09-10T07:38:14 < reportingsjr> dongs: seems to be regularly updated
2015-09-10T07:38:30 < reportingsjr> I was very succesful using it with the plain discovery board and not changing anything there
2015-09-10T07:39:16 < reportingsjr> the st-link detects the correct stm32 IC on my board, but it says it has an error unlocking the flash
2015-09-10T07:39:40 < reportingsjr> is this an issue with my circuit, or with texane st-link do you think?
2015-09-10T07:39:50 < dongs> is it also F0?
2015-09-10T07:39:56 < reportingsjr> F1
2015-09-10T07:40:05 < reportingsjr> the discovery board is F1 as well
2015-09-10T07:40:13 < reportingsjr> my board is STM32F100RC
2015-09-10T07:40:21 < ds2> IIRC, I saw something like that... tracked it down to some power issue
2015-09-10T07:42:45 -!- trepidacious [~trepidaci@217.155.204.2] has joined ##stm32
2015-09-10T07:42:47 < reportingsjr> so I had my board's 3.3V connected to the st-link on the discovery board. Removed it just to test and now I am getting errors that the Chip ID is unknown
2015-09-10T07:43:02 < reportingsjr> looks like the discovery board is only 2.9V while my board is 3.3v
2015-09-10T07:43:54 < dongs> packed with SO MUCH AMAZING NEW TECHNOLOGY

2015-09-10T07:48:14 < dongs> nope, ive ran them over coat hangers
2015-09-10T07:48:18 < dongs> stlink is so slow it doesnt matter
2015-09-10T07:48:21 < reportingsjr> it seems like sometimes I can get it to identify the IC, but other times it wont
2015-09-10T07:48:24 < reportingsjr> hmmm, ok
2015-09-10T07:48:44 < englishman> ive had noise issues :(
2015-09-10T07:48:44 < reportingsjr> It can load stuff in SRAM, but not FLASH
2015-09-10T07:49:15 < dongs> sounds like your power is failing
2015-09-10T07:50:53 < reportingsjr> hmmm, I don't have a scope to check out the power unfortunately
2015-09-10T07:51:13 < reportingsjr> strange because I've loaded the 3.3v PSU at 500mA and it seemed pretty solid
2015-09-10T07:52:17 < jpa-> i have had some issues where openocd used to drop connection, but i never found out if it was openocd bug or too long wires
2015-09-10T07:52:42 < jpa-> reportingsjr: maybe your cables / connectors are crappy?
2015-09-10T07:54:30 < ds2> it is pretty nice to be able to use op-amps w/o having to deal with bypassing and other non idealness of real op-amps
2015-09-10T07:54:42 < upgrdman> hate to be an apple fag, but the ipad pro is kinda tempting.
2015-09-10T07:55:11 < emeb_mac> ds2: what "non-real" op-amps are you talking about?
2015-09-10T07:55:28 < ds2> emeb_mac: messing with the PSoC5 stuff
2015-09-10T07:55:38 < upgrdman> i just wonder what the surface pro 4 will pack, and when it'll be out
2015-09-10T07:55:41 < emeb_mac> ds2: ah - how you like that?
2015-09-10T07:55:50 < ds2> wanted something quick and dirty to test some analog sensors
2015-09-10T07:56:07 < ds2> emeb_mac: for slower stuff, it is a nice virtual bread board
2015-09-10T07:56:09 < emeb_mac> ds2: I'd guess PSoC would be good for slow analog sensors
2015-09-10T07:56:41 < ds2> not sure about good... it ain't cheap
2015-09-10T07:56:49 < emeb_mac> I think they wouldn't be much good for bandwidth > 10kHz or so.
2015-09-10T07:57:24 < emeb_mac> I've done some audio with it, but it wasn't really cut out for that.
2015-09-10T07:57:25 < ds2> i just wanted something that can let me play with the sensors without spending hours breadboarding and figuring out what the op-amp is oscillating in the mess known as a plug in bread board
2015-09-10T07:57:33 < emeb_mac> yup
2015-09-10T07:57:47 < ds2> emeb_mac: it supposely can run the ADC up to 1Msps
2015-09-10T07:58:48 < ds2> might play with the UDB stuff in verilog as a verilog learning platform
2015-09-10T07:59:35 < ds2> oh and the route to any pin feature is really nice
2015-09-10T08:00:10 < reportingsjr> jpa-: yeah, the cables are very mediocre
2015-09-10T08:00:44 < reportingsjr> jpa-: I'm surprised it can ID the chip and write to to sram, but not be able to write flash
2015-09-10T08:01:16 < jpa-> so it always IDs and accesses SRAM correctly?
2015-09-10T08:01:38 < jpa-> if it is intermittent, it would just mean that flash operations are long enough for it to fail there
2015-09-10T08:01:48 < jpa-> but the flash write routines can crash for other reasons also
2015-09-10T08:01:58 < ds2> too much voltage drop?
2015-09-10T08:02:26 < jpa-> reportingsjr: does resetting the cpu through the debugger work? have you tried doing "monitor reset halt" or similar before programming?
2015-09-10T08:02:29 < reportingsjr> ds2: the board and programmer power are separate
2015-09-10T08:02:47 < reportingsjr> jpa-: not sure how to do that with GDB/st-link
2015-09-10T08:02:54 < jpa-> use openocd
2015-09-10T08:03:06 < ds2> reportingsjr: and you sure the voltages are the same or within a schottky drop of each other?
2015-09-10T08:03:12 < jpa-> failure is the normal operating mode of texane stlink
2015-09-10T08:03:39 < reportingsjr> hah, ok. OpenOCD looked a lot more complicated than texane stlink which is why I avoided it.
2015-09-10T08:04:06 < jpa-> yeah, that's true

2015-09-10T11:34:12 < Ecco> but I think I found the answer
2015-09-10T11:34:35 < Ecco> in fact it's just a matter of doing . = ORIGIN(region) + LENGTH(region)
2015-09-10T11:34:41 < Ecco> instead of . += something

2015-09-10T13:42:46 < dongs> not awful
2015-09-10T13:42:53 < Ecco> Indeed :-D
2015-09-10T13:42:56 < Ecco> Not clean by any means either
2015-09-10T13:43:03 < Ecco> It's a little bit off
2015-09-10T13:43:09 < Ecco> but meh, it works
2015-09-10T13:43:33 < Ecco> I wonder if there's a bridge on the left though
2015-09-10T13:43:34 < Ecco> Maybe…
2015-09-10T13:43:44 < dongs> i was half-expecting something like this http://static.rcgroups.net/forums/attachments/3/2/4/0/5/7/a4905920-1-DSCN7690.JPG

2015-09-10T13:44:01 < Ecco> :-D
2015-09-10T13:44:15 < Ecco> Well the first one is just a board that has gathered dust
2015-09-10T13:44:22 < dongs> no
2015-09-10T13:44:26 < Ecco> the second one otoh…
2015-09-10T13:44:27 < PeterM> ecco, you need more flux, i cna tell because your caps and shit have little pointy bits on the solder
2015-09-10T13:44:40 < Ecco> PeterM: Ok, good point
2015-09-10T13:44:52 < Ecco> I was confused about how to use flux with SMD caps
2015-09-10T13:45:01 < Ecco> I did put some
2015-09-10T13:45:05 < Ecco> but I think not at the right time
2015-09-10T13:45:20 < Ecco> How am I supposed to solder these parts?
2015-09-10T13:45:23 < dongs> http://static.rcgroups.net/forums/attachments/3/2/4/0/5/7/a4193644-190-DSCN6111.jpg
2015-09-10T13:45:32 < PeterM> just put some flux on the join and tap wiht hot iron and watch the join become a perfect fillet
2015-09-10T13:45:35 < ReadError> lol
2015-09-10T13:45:43 < ReadError> yes do the opposite of tom66
2015-09-10T13:45:48 < ReadError> and you should be okay
2015-09-10T13:45:56 < Ecco> No but I mean
2015-09-10T13:46:04 < Ecco> When should I add solder?
2015-09-10T13:46:09 < Ecco> I tried tinning the pads
2015-09-10T13:46:16 < Ecco> and then attaching the caps
2015-09-10T13:46:19 < dongs> thats an oshpark board too
2015-09-10T13:46:19 < ReadError> get your hot air?
2015-09-10T13:46:22 < dongs> the last tom66 pic
2015-09-10T13:46:25 < dongs> ReadError: its on the way
2015-09-10T13:46:28 < dongs> he ordered some.
2015-09-10T13:46:28 < Ecco> ReadError: not yet
2015-09-10T13:46:30 < PeterM> first, are you using paste, wire, hot air or iron?
2015-09-10T13:46:33 < ReadError> I normally paste all the passives
2015-09-10T13:46:39 < Ecco> At this point, iron
2015-09-10T13:46:45 < ReadError> but for qfn/tqfp etc I tin->reflow
2015-09-10T13:46:48 < ReadError> do all them first
2015-09-10T13:46:53 < ReadError> then do all the other easy shit
2015-09-10T13:47:00 < Ecco> That's what I did :)
2015-09-10T13:47:04 < Ecco> I started with the qfn
2015-09-10T13:47:28 < Ecco> But for caps and resistors, If I tin first
2015-09-10T13:47:38 < Ecco> then I cannot place the capacitor right on the board
2015-09-10T13:47:52 < Ecco> there's an air gap between the cap and the PCB
2015-09-10T13:48:00 < Ecco> because I cannot melt both pads at once
2015-09-10T13:48:06 < PeterM> for hand soldering passives, i heavily tin one side of the pad, place part, and hit with iron to tack it down, sodler the other side like normal, put some flux on the first side and then hit with iron to properly reflow first side agian
2015-09-10T13:48:16 < Ecco> oooh
2015-09-10T13:48:17 < dongs> ^ yep this
2015-09-10T13:48:18 < ReadError> yea 3 hits
2015-09-10T13:48:22 < ReadError> not fun but works
2015-09-10T13:48:31 < Ecco> ok, got it
2015-09-10T13:48:33 < dongs> been a loong time since I ihandsoldered tho
2015-09-10T13:48:44 < Ecco> That's very helfup
2015-09-10T13:48:48 < Ecco> so, to summarize
2015-09-10T13:48:57 < Ecco> 1/ Tin one pad, no flux needed at this point
2015-09-10T13:49:05 < ReadError> you can always use flux
2015-09-10T13:49:07 < Ecco> ok :)
2015-09-10T13:49:13 < ReadError> but your solder prolly has some in it
2015-09-10T13:49:20 < Ecco> Indeed
2015-09-10T13:49:24 < PeterM> but usually for the first pad it doesnt matter because you're going to go back over i9t
2015-09-10T13:49:30 < Ecco> I had one w/o flux, so I bought a newer pack that has some flux inside
2015-09-10T13:49:44 < Ecco> Gotcha
2015-09-10T13:49:57 < Ecco> then 2/ Place component, only attach first pad
2015-09-10T13:50:05 < Ecco> 3/ Tin *other* pad
2015-09-10T13:50:21 < Ecco> 4/ Add some flux on the other pad, ensure the joint is nice
2015-09-10T13:50:30 < Ecco> 5/ Come back to first pad, add flux, re-heat with iron
2015-09-10T13:50:34 < Ecco> is that it?
2015-09-10T13:50:48 < dongs> no need flux really if you got solder w/rosin core stuff
2015-09-10T13:50:51 < dongs> not for passives
2015-09-10T13:50:53 < Ecco> ok
2015-09-10T13:51:18 < Ecco> But my solders are kinda ugly
2015-09-10T13:51:25 < Ecco> I mean, they do indeed have pointy ends
2015-09-10T13:51:34 < Ecco> Even though the solder I used did have rosin core
2015-09-10T13:56:38 < PeterM> also, most important step: clean your fucking board when you're done - you can't see shit if there is flux residue over everyfuckingthing
2015-09-10T13:57:07 < PeterM> you seem to have that undercontrol though
2015-09-10T13:57:14 < Lux> Ecco: looks pretty decent for hand soldering it

2015-09-10T14:01:19 < Ecco> Lux: thanks :)
2015-09-10T14:01:35 < Ecco> PeterM: Yeah, I drowned the board in ethanol
2015-09-10T14:01:47 < Ecco> (I couldn't find IPA, but apparently that did the job)
2015-09-10T14:02:03 < Ecco> And yes, you're very right, it was a total mess with flux all around the place
2015-09-10T14:02:28 < Laurenceb> russian board?
2015-09-10T14:02:42 < PeterM> IPA is often used instead of ethanol because ethanol can be very expensive (tazes) or have denaturents that leave residue
2015-09-10T14:02:52 < Lux> that stuff is also pretty nice for cleaning pcbs: http://at.farnell.com/kontakt-chemie/kontakt-lr-400-ml/leiterplattenreiniger-400ml/dp/3047453
2015-09-10T14:02:55 < PeterM> *taxes
2015-09-10T14:03:38 < BrainDamage> depends on the denaturant, some places uses bitrex, some uses methanol, etc
2015-09-10T14:04:18 < Ecco> Well, thing is I can purchase ethanol at my local drugstore
2015-09-10T14:04:27 < Ecco> whereas IPA was nowhere to be found
2015-09-10T14:04:31 < Ecco> sure it's not 100% pure
2015-09-10T14:04:40 < PeterM> i did say often, not always
2015-09-10T14:04:44 < Ecco> :-)
2015-09-10T14:05:03 < Ecco> Oh I didn't say you were wrong: IPA most likely *would* be cheaper
2015-09-10T14:05:07 < Ecco> if I could find it…
2015-09-10T14:05:36 < Ecco> Some dude on YouTube recommended a mix of Acetone + IPA
2015-09-10T14:05:56 < Ecco> I didn't dare putting any acetone on my board though, that shit absolutely destroys plastics in general
2015-09-10T14:06:56 < PeterM> eyah, anyone who uses acetone is a nutcase
2015-09-10T14:07:30 < PeterM> i use http://www.mgchemicals.com/products/solder/flux-removers/flux-remover-for-pc-boards-4140/ or IPA depending on what i can get cheapest

2015-09-10T17:03:20 < Ecco> Guys, I need some help on DMA
2015-09-10T17:03:43 < Ecco> Correct me if I'm wrong, but the whole concept of DMA is to have "something" handle some memory transfers while the CPU is busy doing something else
2015-09-10T17:03:58 < Ecco> So let's say I want to drive a screen over SPI
2015-09-10T17:04:07 < Ecco> And that I opt for a framebuffer approach
2015-09-10T17:04:29 < Ecco> It seems like a good candidate for DMA: "something" could stream that memory region to the LCD panel, while the CPU does something else
2015-09-10T17:04:33 < Ecco> Is that correct?
2015-09-10T17:09:20 < Lux> yep

2015-09-10T18:46:46 < Steffann_> Good afternoon Sir
2015-09-10T18:47:21 < Bundestrojaner> upgrdman_: thx for your f0lib you showed me yesterday :)
2015-09-10T18:48:01 < upgrdman_> sure
2015-09-10T18:48:05 < upgrdman_> got things working?
2015-09-10T18:49:29 < upgrdman_> kakimir, in case your question was serious: no, but the media likes to do short wanker memorial clips of firefighters, etc.
2015-09-10T18:51:38 < Bundestrojaner> upgrdman_:  not yet, i guess some setting is missing...
2015-09-10T18:51:38 < Bundestrojaner> so i looked at your code what you do - you use the same i2c-pins as I do: PB6,PB7. So i just call the same functions as you do: http://paste.ubuntu.com/12329152/
2015-09-10T18:51:38 < Bundestrojaner> but i still get no communication on my i2c-bus...
2015-09-10T18:52:20 < Bundestrojaner> pullup is disabled because my eeprom has pullups soldered on the board
2015-09-10T18:52:52 < upgrdman_> Bundestrojaner, you might need to change the 1 to 2, but it's been a while, so i might be wrong.
2015-09-10T18:53:07 < upgrdman_> more importantly: have you scopes the pins? is there a waveform?
2015-09-10T18:54:29 < Bundestrojaner> upgrdman_: you mean the parameter byteCount?
2015-09-10T18:54:29 < Bundestrojaner> i have my scope connected, SCL and SDA are =VCC all the time...
2015-09-10T18:54:37 < upgrdman_> ya
2015-09-10T18:54:40 < upgrdman_> ok
2015-09-10T18:54:41 < upgrdman_> hmm
2015-09-10T18:55:50 < Bundestrojaner> upgrdman_: Some src i found a while ago does: GPIO_PinAFConfig(GPIOB, GPIO_PinSource6, GPIO_AF_1);
2015-09-10T18:55:50 < Bundestrojaner> I didn't found that in your lib, but since it worked for you...

2015-09-10T19:02:49 < upgrdman_> the enum maps every pin to an interger. the function argument is just one of those values.
2015-09-10T19:03:03 < upgrdman_> and the integer mapped to each pin must be correct.

2015-09-10T19:05:47 < upgrdman_> or if you prefer, do something like "#define SCK PB6" etc.
2015-09-10T19:06:20 < Bundestrojaner> upgrdman_: thx, i'll try it :)
2015-09-10T19:07:31 < upgrdman_> oh the enum is defined in my gpio.h... so you dont need to redefine it in main()
2015-09-10T19:07:55 < upgrdman_> so all you need is: gpio_setup(PB6, AF, OPEN_DRAIN, FIFTY_MHZ, NO_PULL, AF1); // sck
2015-09-10T19:07:56 < upgrdman_> gpio_setup(PB7, AF, OPEN_DRAIN, FIFTY_MHZ, NO_PULL, AF1); // sda
2015-09-10T19:07:56 < Bundestrojaner> yeah, i thought so. but i'm not very familiar with enums...
2015-09-10T19:08:15 < Bundestrojaner> PB6 is now 22 and PB7 is 23 (according to debug)
2015-09-10T19:08:21 < Bundestrojaner> but it still don't work :(
2015-09-10T19:09:13 < upgrdman_> do your pins works as normal IOs?
2015-09-10T19:09:23 < upgrdman_> e.g. are you sure your chip is broken
2015-09-10T19:10:16 < upgrdman_> isn't*
2015-09-10T19:10:51 < Bundestrojaner> upgrdman_: atleast pull_up works and pulls the pins up
2015-09-10T19:11:00 < upgrdman_> k
2015-09-10T19:16:39 < Bundestrojaner> upgrdman_: my pullups are 15K, is that ok?
2015-09-10T19:16:58 < upgrdman_> should be
2015-09-10T19:17:20 < upgrdman_> if not, you'd at least see an analogish square wave on your scope
2015-09-10T19:18:00 < Bundestrojaner> upgrdman_: i always have vcc on both... i try another f0discovery board...
2015-09-10T19:18:42 < upgrdman_> check disco pcb schematic. make sure something on the board isn't already connected to the pins you want to use
2015-09-10T19:19:11 < Bundestrojaner> upgrdman_: shall i try it with PULL_UP and nothing than scope connected? or with the eeprom and NO_PULL?
2015-09-10T19:19:38 < upgrdman_> so your eeprom is the i2c device?
2015-09-10T19:20:35 < upgrdman_> you can leave the eeprom connected to the mcu, and scope the pins. also make sure your eeprom is wired right, and that you are using the correct i2c address.
2015-09-10T19:20:53 < upgrdman_> also, my code does not handle any i2c errors :) so, uh, that could cause problems :)

2015-09-10T19:24:27 < upgrdman_> kakimir, while i agree that muricans often get fixed on that, i think in this case its more of an honorable tribute to people who risked their lives and died.
2015-09-10T19:24:46 < kakimir> yes
2015-09-10T19:25:46 < Bundestrojaner> upgrdman_: with the new controller, i get squares...
2015-09-10T19:26:02 < Bundestrojaner> i think you were right, the old controller is broken
2015-09-10T19:26:38 < upgrdman_> yay (that you found the problem)

2015-09-10T19:27:08 < Bundestrojaner> i hope so
2015-09-10T19:27:24 < Bundestrojaner> now i'll read it with the atmega and see if it wrote the byte

2015-09-11T03:58:00 < reportingsjr> hmm, wtf..
2015-09-11T03:58:18 < reportingsjr> last night I was having issues programming a board with an STM32f100 discovery board
2015-09-11T03:58:27 < kakimir> today all is fine?
2015-09-11T03:58:45 < reportingsjr> I still am, but I found that when I connect /just the ground/ of my board the the discovery that the discovery can't even program it's on board dev IC!
2015-09-11T03:58:51 < reportingsjr> wtf would cause that???
2015-09-11T03:59:39 < kakimir> how are boards powered?
2015-09-11T04:02:23 < reportingsjr> my board is powered by Power over Ethernet, the dev is by USB
2015-09-11T04:02:44 < reportingsjr> the PoE power is isolated
2015-09-11T04:02:48 < reportingsjr> huh..
2015-09-11T04:02:57 < reportingsjr> something I tried yesterday is working..
2015-09-11T04:03:17 < reportingsjr> I tried powering my board from the dev board and it succesfully programmed it
2015-09-11T04:04:21 < kakimir> how about measuring if you have some problems there with ground levels?
2015-09-11T04:04:41 < kakimir> what are you doings if you have poe stuff?
2015-09-11T04:04:49 < kakimir> interesting
2015-09-11T04:05:10 < kakimir> don't say you just power it via ethernet nothing else
2015-09-11T04:06:21 < reportingsjr> kakimir: making a PoE powered door/tool/etc controller
2015-09-11T04:06:48 < reportingsjr> kakimir: has an NFC attachment and the goal is to be able to open doors, turn tools on, etc via NFC cards (for a local hackerspace)

2015-09-11T08:17:43 < emeb_mac> zyp: strange thing - with the latest launchpad toolchain I was having some strange stuff going on in the shell after running arm-none-eabi-gdb for BMP flashing
2015-09-11T08:18:04 < emeb_mac> found I needed to add a "stty sane" afterwards to reset the terminal to something usable.
2015-09-11T08:18:08 < emeb_mac> dunno why
2015-09-11T08:18:47 < emeb_mac> it may be related to BMP
2015-09-11T08:18:53 < emeb_mac> which I doubt you use.
2015-09-11T08:19:20 < zyp> emeb_mac, I guess for some weird reason, gdb touches terminal settings when in batch mode and doesn't reset them
2015-09-11T08:19:28 < emeb_mac> zyp: yes
2015-09-11T08:20:27 < emeb_mac> I had been doing a "reset" but that also cleared out any msgs from the flash process
2015-09-11T08:20:43 < emeb_mac> stty sane however doesn't clear the screen, so that's better.

2015-09-11T17:50:18 < Ecco> Hmm, so I've this LCD panel from buydisplay.com
2015-09-11T17:50:39 < Ecco> And I feel like the LCD controller is *not* the one they say it is
2015-09-11T17:50:56 < Ecco> (The datasheet says data is encoded as 3pixels/byte (awful, but well)
2015-09-11T17:51:07 < Ecco> and in practice, it looks like it is in fact 2pixels/byte
2015-09-11T17:51:27 < Ecco> Question: is it possible that they changed the controller? If so, how can I tell which controller this is?
2015-09-11T17:51:50 < upgrdman_> yes, it's not uncommon for them to change things without telling you
2015-09-11T17:51:55 < Ecco> ok
2015-09-11T17:53:02 < Ecco> I did have a previous item of the "very same" display
2015-09-11T17:53:06 < Ecco> but the markings are a bit different
2015-09-11T17:53:15 < Ecco> Unfortunately the controller is not visible…
2015-09-11T17:53:28 < upgrdman_> as for how to tell, there's no standard, like "reg x contains the model number" :(
2015-09-11T17:53:36 < Ecco> hmm, ok
2015-09-11T17:53:39 < upgrdman_> so visually is about it. if the die is exposed
2015-09-11T17:53:44 < Ecco> it's not :(

2015-09-11T18:19:16 < Ecco> it's close though

2015-09-11T18:54:32 < Ecco> Hmm
2015-09-11T18:54:36 < Ecco> Ok, now I hav a weird issue
2015-09-11T18:54:43 < Ecco> depending on the amount of white or black pixels
2015-09-11T18:54:48 < Ecco> apparently, the contrast of the panel changes
2015-09-11T18:54:53 < upgrdman_> lol
2015-09-11T18:54:54 < Ecco> is that normal?
2015-09-11T18:55:05 < upgrdman_> not for me
2015-09-11T18:55:20 < Ecco> ok :)
2015-09-11T18:55:32 < upgrdman_> does your lcd use external caps for the boost circuit?
2015-09-11T18:55:35 < Ecco> Yes
2015-09-11T18:55:42 < upgrdman_> maybe they're too small?
2015-09-11T18:55:48 < upgrdman_> and voltage dips under load
2015-09-11T18:55:58 < Ecco> Oh
2015-09-11T18:56:24 < Ecco> Well, supposedly I used what's recommended by the manufacturer
2015-09-11T18:56:37 < mitrax> upgrdman_: for TFT that wouldn't matter though would it? isn't the backlight supposed to be the same all the time?
2015-09-11T18:56:41 < upgrdman_> mlcc? don't forget about derating with DC
2015-09-11T18:56:49 < upgrdman_> mitrax, not backlight
2015-09-11T18:56:59 < upgrdman_> mitrax, drive voltages for the TFT itself
2015-09-11T18:57:10 < upgrdman_> the transistors on the glass need >3V iirc
2015-09-11T18:57:17 < upgrdman_> like 7.someshit for one of my lcds
2015-09-11T18:58:07 < upgrdman_> that is what the contrast pin or register does
2015-09-11T18:58:15 < Ecco> This is a B&W display
2015-09-11T18:58:18 < upgrdman_> it dicks with the charge pump to adjust that voltage
2015-09-11T18:58:20 < Ecco> I'm not using any backlight
2015-09-11T18:58:21 < upgrdman_> yes exactly
2015-09-11T19:01:18 < mitrax> upgrdman: okay i was under the impression TFTs didn't need a boost circuit, only the backlight part, guess i'm wrong
2015-09-11T19:01:35 < upgrdman_> i learned the hard way :)
2015-09-11T19:01:49 < upgrdman_> "wtf do i need these caps for? i'm not going to populate them"
2015-09-11T19:02:32 < Ecco> Holy shit it's dramatic
2015-09-11T19:02:39 < Ecco> Ok so I fill up the screen with white pixels
2015-09-11T19:02:39 < upgrdman_> fixed? :)
2015-09-11T19:02:44 < Ecco> Nope
2015-09-11T19:02:58 < Ecco> I just added a delay between each pixel
2015-09-11T19:03:02 < Ecco> and the more I add white pixels
2015-09-11T19:03:06 < Ecco> the darker the screen gets !
2015-09-11T19:03:11 < upgrdman_> you could probe the caps to see if the voltage is actually dipping
2015-09-11T19:03:19 < Ecco> Ok let me do just that
2015-09-11T19:03:27 < Ecco> What should I measure exactly
2015-09-11T19:03:28 < Ecco> ?
2015-09-11T19:03:32 < upgrdman_> the voltage
2015-09-11T19:03:39 < Ecco> around the caps?
2015-09-11T19:03:50 < upgrdman_> ya. so there's two of them, right?
2015-09-11T19:04:05 < upgrdman_> measure all four terminals. one will be ~VDD*2.
2015-09-11T19:04:07 < Ecco> there's a bunch actually
2015-09-11T19:04:23 < upgrdman_> schematic?
2015-09-11T19:04:35 < Ecco> Sure
2015-09-11T19:04:58 < Ecco> http://i.imgur.com/USXWGbm.png
2015-09-11T19:05:48 < upgrdman_> hmm maybe c9
2015-09-11T19:06:11 < Ecco> yes so c9 is ~15V
2015-09-11T19:06:27 < Ecco> 14.5
2015-09-11T19:06:31 < upgrdman_> ok
2015-09-11T19:06:41 < upgrdman_> does it dip as your add pixels
2015-09-11T19:07:32 < Ecco> lemme see
2015-09-11T19:08:47 < Ecco> nah
2015-09-11T19:08:49 < Ecco> it changes
2015-09-11T19:08:58 < Ecco> it starts at ~13V
2015-09-11T19:09:02 < Ecco> nothing dramatic though
2015-09-11T19:09:03 < Ecco> Also
2015-09-11T19:09:07 < Ecco> Ok, let me make a video
2015-09-11T19:09:16  * upgrdman_ waits patiently

2015-09-11T19:13:04 < upgrdman_> hmm
2015-09-11T19:13:16 < upgrdman_> looks like boost voltage is rising, making it blacker
2015-09-11T19:13:21 < upgrdman_> not sure why.
2015-09-11T19:14:01 < upgrdman_> maybe some other pros can chime in
2015-09-11T19:14:53 < Ecco> If I "hotplug" another cap around C9, the displays gets better for a few secs
2015-09-11T19:14:55 < Ecco> and turns darker again

2015-09-11T19:21:11 < upgrdman_> what did you change to fix it
2015-09-11T19:21:21 < Ecco> Some stuff in the init sequence
2015-09-11T19:21:32 < Ecco> copy-pastaed from the Chinese sample code
2015-09-11T19:21:39 < upgrdman_> lol
2015-09-11T19:21:47 < Ecco> I decided to roll-out my own init method (I like to understand what my code does)
2015-09-11T19:21:53 < Ecco> apparently, it was missing something
2015-09-11T19:22:08 < Ecco> which isn't that surprising given that the datasheet is very likely not the good one
2015-09-11T19:23:28 < Ecco> Ok, so one command ajusts Vop, the LCD supply voltage
2015-09-11T19:24:06 < Ecco> the next one the LCD Bias
2015-09-11T19:24:10 < Ecco> and the last one the LCD booster

2015-09-11T20:05:08 < upgrdman_> that's kinda neat
2015-09-11T20:05:12 < Ecco> It does
2015-09-11T20:05:43 < Ecco> That is
2015-09-11T20:05:49 < Ecco> *but* the pixel format is awful
2015-09-11T20:05:57 < upgrdman_> agreed
2015-09-11T20:06:18 < Ecco> That pretty much means a framebuffer that is twice as large as needed
2015-09-11T20:06:26 < upgrdman_> i'd prefer xxxxaabb

2015-09-11T20:06:28 < Ecco> (otherwise I can't DMA it)
2015-09-11T20:06:43 < Ecco> well, yes, even that would be better
2015-09-11T20:06:51 < Ecco> or, I don't know… aabbccdd maybe????
2015-09-11T20:06:57 < Tectu> four shades of graz
2015-09-11T20:06:58 < Tectu> gray
2015-09-11T20:07:01 < Ecco> :-D
2015-09-11T20:07:03 < upgrdman_> no, thats to convenient

2015-09-11T20:07:31 < upgrdman_> i do kinda miss monochrome lcds. 8 pixels per byte FTW
2015-09-11T20:07:39 < Ecco> Oh wait
2015-09-11T20:07:44 < Ecco> that display also does B&W
2015-09-11T20:07:53 < Ecco> ... with the same brain-dead pixel format
2015-09-11T20:08:00 < Ecco> where AA and BB can either be 11 or 00
2015-09-11T20:08:06 < upgrdman_> theres no register to change the byte format?
2015-09-11T20:08:11 < Ecco> not that I know of
2015-09-11T20:08:22 < Ecco> but once again, apparently I don't have the right datasheet
2015-09-11T20:08:23 < upgrdman_> like most color lcds let you pack the r/g/b in a few different ways

2015-09-12T01:39:44 < jadew> but I don't want some marketing type get his hands on it, make it pink and practically steal it from me
2015-09-12T01:40:23 < jadew> seems to happen a lot, because people don't think about this when they decide on the license they really want
2015-09-12T01:42:58 < dos_fan]> MS-RSL is the obvious choice
2015-09-12T01:43:31 < dos_fan]> for some stuff it's good to avoid a gazillion broken forks
2015-09-12T01:44:00 < jadew> I'm not really worried about the broken forks, normally I don't release opensource and when I do, I use MIT
2015-09-12T01:44:14 < dos_fan]> me too
2015-09-12T01:44:17 < jadew> but this is the kind of project that might require constant maintenance for a longer period of time
2015-09-12T01:44:33 < kakimir> that sucks
2015-09-12T01:44:34 < dos_fan]> generally those who will abuse a license don't give a shit anyway
2015-09-12T01:44:36 < jadew> and I'd hate it if a year later some faggot puts another name on it and makes it his
2015-09-12T01:44:44 < dos_fan]> so really, it doesn't matter what you license it under
2015-09-12T01:45:29 < dos_fan]> this was my experience anyway with a popular project released under ms-rsl
2015-09-12T01:46:16 < jadew> interesting licenses
2015-09-12T01:46:36 < jadew> I guess I need one where the user can modify the code for his own use but can't redistribute modifications

2015-09-12T01:52:11 < artag> you don't have to use an existing license. it just makes life easier because people already (allegedly) understand the restrictions. If you want to make a license that allows reuse but not redistribution, just write it up
2015-09-12T01:52:45 < Roklobsta> but who will enforce it?  like anything - patents, copyright, trademarks etc unless you front up and defend your turf ($$$$) you'd get run roughshod over.
2015-09-12T01:52:52 < jadew> I suppose that's what I have to do
2015-09-12T01:52:53 < artag> Be aware that it pretty much makes your code useless for anything except commercial products though
2015-09-12T01:53:11 < artag> why would anyone but you enforce your licence ?
2015-09-12T01:53:30 < Roklobsta> i'm saying it's not automatic and it will usually cost money.
2015-09-12T01:53:34 < jadew> artag, why only for commercial products?
2015-09-12T01:53:55 < jadew> it's a framework, so people can write whatever they want using it
2015-09-12T01:54:09 < jadew> as long as they don't change it/rename it/pretend it's theirs
2015-09-12T01:54:13 < upgrdman> sounds super gay
2015-09-12T01:54:34 < dos_fan]> uh
2015-09-12T01:54:39 < jadew> well, they can change it, but not pretend it's theirs
2015-09-12T01:54:41 < jadew> upgrdman, why?
2015-09-12T01:54:49 < upgrdman> im just trolling
2015-09-12T01:54:58 < upgrdman> it's nice enough that you plan to share
2015-09-12T01:55:02 < artag> because that's what we see in practice. atmel  and microchip offer usb and ip stacks but you can't use them in an opensource product because they have to be refetched from the author, not included with other sources
2015-09-12T01:55:03 < dos_fan]> there are times when you want to make source available but only for an insight into something
2015-09-12T01:55:17 < artag> too much trouble, nobody cares, there are better options
2015-09-12T01:55:31 < upgrdman> but seriously, if you dont want people to fuck with your code, keep it closed. once it's out, people wont pay attention to your requests
2015-09-12T01:55:49 < dos_fan]> upgrdman: definitely
2015-09-12T01:56:10 < jadew> upgrdman, I'm not really worried about the minor fork
2015-09-12T01:56:35 < upgrdman> what about a "major" fork? wtf are you going to do? hire a laywer and wage a lawsuit? go broke trying.
2015-09-12T01:56:36 < dos_fan]> people just slap the GPL on it and stick it on gayhub
2015-09-12T01:56:38 < artag> commercially you can use them, but if you do, you've locked yourself in. That's why you get companies who say they want to offer sources, but can't because of someone else's IP that they used when they built it
2015-09-12T01:56:42 < artag> it's a dead end
2015-09-12T01:57:43 < jadew> I guess I can see the problem
2015-09-12T01:58:32 < artag> rename it, pretend it's theirs, sure, i see your point. but all the open source stuff I've ever looked at seems to have the original author credited
2015-09-12T01:59:09 < jadew> that means very little when you don't have control over the project anymore
2015-09-12T01:59:12 < artag> and I have no use for code I can't change. I might as well use a closed source one, I've got no benefit except I can see how it works
2015-09-12T01:59:32 < jadew> that's the thing, I have no problem against changing
2015-09-12T01:59:52 < jadew> I have a problem against changing and releasing it as something new
2015-09-12T02:00:26 < jadew> but it's kinda hard to prohibit precisely that, without leaving loopholes
2015-09-12T02:00:28 < Roklobsta> if you care about control, don't opensource it.  release binaries, lib/dll and headers only
2015-09-12T02:01:21 < artag> ok. but here's a thing. every time I make something with arduino, I find the libraries deficient. not just buggy (lets assume your code has no bugs) but doesn't do something I need it to do - like the early i2c code that couldn't clock-stretch.
2015-09-12T02:01:52 < artag> So I need to extend it before it's any use to me. And now I can't ship sources any more, because they're not identical to yours
2015-09-12T02:02:28 < jadew> artag, you can fork and generate a pull request
2015-09-12T02:02:41 < jadew> artag, yes, that's the loophole
2015-09-12T02:02:45 < artag> I could maybe work around it, or layer an extra feature. But I'll probably look elsewhere unless it's *amazing*
2015-09-12T02:02:47 < jadew> because my intention would be to allow that

2015-09-12T02:03:51 < artag> maybe you could make it work, if youy respond well to pull requests. some people do, especially when the code is young and they care about it. But mostly it gets forgotten, or the author is too busy etc.
2015-09-12T02:04:10 < jadew> dos_fan], I know, but I'd rather have a satisfactory license to begin with
2015-09-12T02:04:27 < artag> in that case, for myself, I'd rather it was forked and politely kept my name in it. But the new additions deserve credit too

2015-09-12T02:06:54 < dos_fan]> it has an acceptable plugin model which we encourage instead

2015-09-12T02:17:02 < artag> i tend to feel that if I could write it, anyone could. So why sweat it ? :)
2015-09-12T02:18:22 < Bundestrojaner> jadew: as upgrdman already said, if you have a license, you also have to enforce it.
2015-09-12T02:19:08 < jadew> Bundestrojaner, not really a problem
2015-09-12T02:19:11 < Bundestrojaner> and that won't work in countries in Asia...
2015-09-12T02:19:18 < jadew> that's true
2015-09-12T02:19:50 < jadew> but again, it's better having a license that reflects your intentions than not
2015-09-12T02:20:02 < Bundestrojaner> even the content mafia fails to enforce their rights. and they have not only a legion of lawyers, they even buy the politicians...

2015-09-12T03:24:21 < kakimir> that chip is so called rs232 tranceiver
2015-09-12T03:27:50 < kakimir> tp = toilet paper
2015-09-12T03:28:05 < Roklobsta> yes ok, how long is the twisted pair and how fast are the speeds?  you might be better using rs422?.....
2015-09-12T03:28:24 < kakimir> 15cm
2015-09-12T03:28:53 < Roklobsta> lol ok.
2015-09-12T03:29:54 < kakimir> chip is capable to 1Mbaud so that is it
2015-09-12T03:31:03 < kakimir> no need for 1M
2015-09-12T03:32:48 < kakimir> 115200 or so should be fine
2015-09-12T03:33:04 < kakimir> or 230400
2015-09-12T03:39:02 < PeterM> kakimir, how are you running it over twisted pair?
2015-09-12T03:39:58 < kakimir> 4 pairs for signals
2015-09-12T03:40:03 < kakimir> 1 pair for power
2015-09-12T03:40:25 < PeterM> ok, so you have a differential driver and reciever on booth ends?
2015-09-12T03:40:32 < kakimir> no way
2015-09-12T03:40:39 < kakimir> just ground
2015-09-12T03:41:00 < PeterM> ermmm...
2015-09-12T03:41:47 < PeterM> thats not really how it works/meant to work
2015-09-12T03:41:50 < kakimir> there is no point?=
2015-09-12T03:41:55 < PeterM> yeah
2015-09-12T03:42:00 < kakimir> just understood it :)
2015-09-12T03:42:11 < PeterM> i mean, it helps noise immunity by providing a sort of shield
2015-09-12T03:42:29 < PeterM> but then you should run shielded rather than twisted pair
2015-09-12T03:43:09 < kakimir> it's more like minimizing signal circuit loop area
2015-09-12T03:44:31 < Roklobsta> time for some sun.
2015-09-12T03:44:51 < kakimir> pair twisting is just for mechanical solution
2015-09-12T03:45:34 < kakimir> seperate lines tend to stay seperate

2015-09-12T05:04:20 < upgrdman> i can etch my boards as fast as i want to. like, dangerously fast.
2015-09-12T05:04:24 < jadew> I tried to switch to that too, but didn't have good results
2015-09-12T05:04:30 < jadew> how fast?
2015-09-12T05:04:31 < upgrdman> 35% h2o2 is scary shit.
2015-09-12T05:04:41 < jadew> I only have 3%
2015-09-12T05:04:42 < upgrdman> <2 seconds
2015-09-12T05:04:46 < upgrdman> seriously scary
2015-09-12T05:04:47 < jadew> no way
2015-09-12T05:04:59 < upgrdman> lemme find a video of some fag that did it on youtube
2015-09-12T05:05:28 < upgrdman> if you do equal parts of HCl and H2O2, it's super fast if you use high purity HCL and H2O2
2015-09-12T05:05:46 < upgrdman> i do 1:1:3    hcl:h2o2:h2o
2015-09-12T05:05:51 < upgrdman> and it takes like 1 minute
2015-09-12T05:05:54 < upgrdman> if even
2015-09-12T05:06:01 < jadew> holly crap
2015-09-12T05:06:03 < upgrdman> for 1oz copper

2015-09-12T05:06:36 < jadew> *it's
2015-09-12T05:06:54 < upgrdman> also, hcl/h2o2 doesnt need to be shaken up during etching. just let it sit until it stop bubbling. done.
2015-09-12T05:07:20 < jadew> man, that looks great
2015-09-12T05:07:24 < jadew> how dangerous is it?
2015-09-12T05:07:40 < upgrdman> smells like chlorine gas
2015-09-12T05:07:47 < upgrdman> so uh, be sure to huff it
2015-09-12T05:07:59 < upgrdman> i have no backyard or patio :(
2015-09-12T05:08:09 < jadew> I do my etching in the bathroom
2015-09-12T05:08:18 < upgrdman> when i tried undiluted and tossed in a board... i was honestly scared for my safety.
2015-09-12T05:08:27 < jadew> lol
2015-09-12T05:09:26 < upgrdman> so like $13 for a gallon of HCl and like $43 for a gallon of 35% H2O2... is about a lifetime supply
2015-09-12T05:09:57 < jadew> if you etch a lot
2015-09-12T05:10:07 < jadew> I'd probably end up sharing most of it
2015-09-12T05:10:58 < jadew> I'll give it a try, I'll ask my wife to get me some
2015-09-12T05:12:32 < upgrdman> i amazoned the h2o2

2015-09-12T05:13:03 < jadew> so I don't think I'll be able to find it myself

2015-09-12T05:31:38 < upgrdman> your can surface mount DIPs

2015-09-12T05:32:30 < upgrdman> can, but dont need to
2015-09-12T05:32:37 < upgrdman> just sit it on big pads. solder.
2015-09-12T05:32:45 < upgrdman> here's some PTH headers i surface mounted:

2015-09-12T05:41:44 < kakimir> let's take guesses?
2015-09-12T05:41:56 < upgrdman> idle balancing, or no motor power?
2015-09-12T05:42:03 < jadew> idle balancing
2015-09-12T05:42:28 < kakimir> there is some motor power
2015-09-12T05:42:48 < upgrdman> didn't measure. guessing 0.5-1 amp average, but spikes
2015-09-12T05:42:50 < jadew> I suppose it has to fire those motors very fast
2015-09-12T05:43:00 < jadew> yeah
2015-09-12T05:43:00 < upgrdman> with no motors, it was 75.5mA     http://www.farrellf.com/temp/new_meter.jpg

2015-09-12T05:44:16 < upgrdman> i bought some 600 pulse/rev encoders off of ebay a month ago

2015-09-12T05:47:32 < jadew> added to my collection
2015-09-12T05:47:38 < upgrdman> ya. i wanted >500. digikey/mouser wanted >$50 for first-world encoders
2015-09-12T05:48:23 < upgrdman> bourns has some small 500 or 512 pulse encoders for like $55
2015-09-12T05:48:29 < upgrdman> the size of a potentiometer
2015-09-12T05:48:34 < upgrdman> or just a tad bigger
2015-09-12T05:49:47 < jadew> I'm off to bed, night
2015-09-12T05:50:06 < upgrdman> emeb_mac, FWIW those 600 pulse encoders i got had no play in the shaft, and had just a very slight amount of friction.
2015-09-12T05:50:06 < kakimir> what you need that for?
2015-09-12T05:50:13 < upgrdman> future projects
2015-09-12T05:50:21 < upgrdman> as in, no idea :)
2015-09-12T05:50:25 < emeb_mac> upgrdman: perfect
2015-09-12T05:50:34 < upgrdman> i kinda want to make a cubli type of robot
2015-09-12T05:50:37 < emeb_mac> I want it as a tuning knob for an SDR project
2015-09-12T05:50:51 < upgrdman> emeb_mac, i was also gonna do that, for my servo tester.

2015-09-12T05:51:08 < kakimir> can't you make it work even without encoders?
2015-09-12T05:51:08 < upgrdman> but it's too big for my servo tester
2015-09-12T05:51:34 < upgrdman> kakimir, of course. it works for years with a touchscreen, and recently added a pot
2015-09-12T05:52:11 < upgrdman> but when i use it as a PWM generator, i can enter 32 bit numbers. that's a bitch with a touchscreen, and a pot + 12bit adc isn't anywhere near good enough
2015-09-12T05:52:36 < upgrdman> but with a 600 pulse encoder, it can be great.
2015-09-12T05:52:59 < upgrdman> and with 600 pulses / rev, you can due software velocity and it actually looks smooth because you have enough data points
2015-09-12T05:55:39 < emeb_mac> bought

2015-09-12T05:55:49 < emeb_mac> now wait 3wks
2015-09-12T05:55:59 < upgrdman> took about 1 week to so cal
2015-09-12T05:56:05 < emeb_mac> ah - not bad
2015-09-12T05:56:14 < emeb_mac> ebay .cn always overestimates time
2015-09-12T05:56:25 < upgrdman> well it can be really hit and miss too
2015-09-12T05:56:32 < kakimir> next thing it brings you beer from fridge
2015-09-12T05:56:43 < upgrdman> i had someone ship me some bluetooth modules from shenzhen and it was at my door in 48 hours.
2015-09-12T05:56:54 < emeb_mac> optical - should work nicely with the STM32 2-phase timer encoder interface
2015-09-12T05:56:55 < upgrdman> and other ship stuff from shenzhen and it's 5 weeks
2015-09-12T05:57:21 < upgrdman> emeb_mac, ya. open drain outputs, so works with many logic levels too
2015-09-12T05:57:26 < upgrdman> but needs 5+V for VDD
2015-09-12T05:57:41 < emeb_mac> orly? nuisance, but workable.
2015-09-12T05:58:13 < upgrdman> i didnt try lower. i will. gimme a minute.
2015-09-12T05:58:20 < upgrdman> but rated for 5-24V
2015-09-12T05:58:38 < emeb_mac> might work with 3.3v but likely marginal

2015-09-12T06:25:44 < upgrdman> cool
2015-09-12T06:32:10 < upgrdman> i wonder what would happen if i went to a wal mart and bought a pregnancy test kit, some coat hangers, and a shop vac.

2015-09-12T11:26:11 < upgrdman> :)
2015-09-12T11:26:29 < PeterM> i think we've all done it at some stage
2015-09-12T11:26:44 < upgrdman> gotta find some way to use up my old collection of PTH passives
2015-09-12T11:28:16 < PeterM> yeah, i basically only use th passives for bodges or testing/substitutiuon
2015-09-12T11:33:11 < PeterM> im curious why you didn't connect your coil directly, and you used the other bits of tubing?
2015-09-12T11:37:33 < upgrdman> like why have the long copper tube going to the transistors?
2015-09-12T11:37:41 < upgrdman> two reasons
2015-09-12T11:38:09 < upgrdman> most importantly: weight balance. so it could sit in some tupperware and not tip over
2015-09-12T11:38:48 < upgrdman> and i needed the long ass copper tube so it would be submerged in water at the bottom, where the caps are
2015-09-12T11:39:09 < upgrdman> even with low ESR caps, 30A of ripple current gets them hot enough to boil water :)
2015-09-12T11:39:45 < upgrdman> this is what happens if the caps are not water cooled: http://www.farrellf.com/temp/burned_mlcc_capacitor_taiyo_yuden_UMK325C7106MM-T_50V_10uF.jpg
2015-09-12T11:40:08 < upgrdman> which looked like this http://www.farrellf.com/temp/induction_heater_revC.jpg
2015-09-12T11:40:48 < PeterM> i meant somewhere halfway between the two
2015-09-12T11:41:12 < upgrdman> ? the red wire?
2015-09-12T11:42:17 < upgrdman> oh nm. ya thats so the coil reached out of the tupperware :)
2015-09-12T11:42:35 < PeterM> Ahhhhhh
2015-09-12T11:42:52 < upgrdman> here's an older video showing how i use it

2015-09-12T11:47:10 < PeterM> http://i.imgur.com/5US3nWe.jpg you could use this for your fets
2015-09-12T11:47:21 < PeterM> i have one spare, bnib
2015-09-12T11:49:47 < PeterM> its solid copper (aside from acetal top on it), so you could easily cool your fets, and you could possibly tie it to one side of the coil and solder the caps to it with a torch or something to keep the caps super chill
2015-09-12T11:50:20 < upgrdman> thanks but i have tons of heatsinks laying around
2015-09-12T11:50:33 < upgrdman> like a few cubic feet worth
2015-09-12T11:51:09 < PeterM> fair enough - waterblocks are a little rarer than heatsinks though :P

2015-09-12T17:50:46 < zyp> and do
2015-09-12T17:50:58 < Tectu> Cryptosystems using keys larger than 40 bits were then considered munitions within the definition of the US export regulations
2015-09-12T17:51:01 < Tectu> wtf

2015-09-12T17:51:32 < Tectu> if they have a proper law again it sure. but that way I can´t really respect who ever is responsible for that

2015-09-12T17:54:39 < dongs> crystal is oscillating at 24mhz
2015-09-12T17:54:42 < dongs> ...
2015-09-12T17:54:46 < dongs> yet its a 12mhz xtal
2015-09-12T17:54:49 < dongs> wat gives
2015-09-12T17:55:20 < Tectu> zyp, that is why I don´t understand that they didn´t came up with a real law addressing exactly that within all those years
2015-09-12T17:55:40 < Tectu> zyp, ~1942 to 1993 is a lot of time to come up with a proper law
2015-09-12T17:56:01 < zyp> what's improper about the one that existed?

2015-09-12T17:56:43 < dongs> tectu
2015-09-12T17:56:50 < dongs> lemme summarize this in like one sentence
2015-09-12T17:57:09 < dongs> crypto is considered munition cuz it can be used to encrypt military stuff that could give one country advantage over another.
2015-09-12T17:57:41 < Tectu> zyp, anyway, thanks for the remark about software being restricted too
2015-09-12T17:57:46 < zyp> Tectu, check the definition of the word «munition»
2015-09-12T17:57:58 < zyp> the enigma machine could certainly be classified as such
2015-09-12T17:58:05 < Tectu> zyp, so when some smart math IT guy comes up with a new super duper strong algorithm he cannot just publish it?
2015-09-12T17:58:12 < zyp> dongs, crystal loading way off?
2015-09-12T17:58:48 < dongs> naw
2015-09-12T17:59:02 < dongs> its not gonna be off to make 12 into 24mhz
2015-09-12T17:59:23 < dongs> my theory is china was making both and 24mhz one jumped into 12mhz pile and got labeled as 12
2015-09-12T17:59:29 < dongs> its oscillating at like 23.98 or so

2015-09-12T22:14:52 < emeb> FOSS tools are still fragile - openocd doesn't support it yet. BMP support is there but doesn't work reliably.
2015-09-12T22:15:28 < emeb> Tried on Win / Keil - JLink doesn't see it. ST-Link V2 doesn't see it either.
2015-09-12T22:15:31 < PaulFertser> openocd doesn't support it unless you use an out of tree patch.
2015-09-12T22:15:55 < PaulFertser> I think they provided a new firmware version for stlink that supports it.
2015-09-12T22:16:16 < emeb> PaulFertser: I have the latest ST-Link firmware and Utility. That works.

2015-09-13T00:23:08 < emeb> ok - here's a funny one: working on F7 and I've seen the system hang when I try to set the clock pll
2015-09-13T00:23:23 < emeb> backtrace shows it in the default handler
2015-09-13T00:23:38 < emeb> so I added a bunch of specific handlers
2015-09-13T00:23:50 < emeb> turns out it's in SysTick
2015-09-13T00:23:55 < emeb> but I never enabled SysTick
2015-09-13T00:24:12 < emeb> and it doesn't hang when not setting the clock
2015-09-13T00:25:43 < mtbg> do you switch to other clock source before setting the pll and wait until pll is ready after setting it before switching core clock source?
2015-09-13T00:25:52 < emeb> yes
2015-09-13T00:26:19 < mtbg> did you set flash wait states properly?
2015-09-13T00:26:23 < emeb> yes
2015-09-13T00:26:32 < emeb> using code straight outta the ST examples.
2015-09-13T00:26:38 < emeb> makes heavy use of HAL routines.
2015-09-13T00:26:47 < emeb> maybe the HAL stuff is turning on Systick?
2015-09-13T00:39:32 < emeb> yep - HAL turns on systick but apparently doesn't provide a handler.
2015-09-13T00:43:35 < zyp> heh
2015-09-13T00:44:08 < zyp> well, it probably assumes systick is already set up, and just configures it for the new freq
2015-09-13T00:46:39 < emeb> there is a routine in HAL that must be called from SysTick_Handler but they want you to define the handler and call the routine.
2015-09-13T00:47:34 < emeb> note that this is my first time fooling around with HAL.
2015-09-13T00:50:46 < emeb> It's deceptively similar to StdPeriph, but has enough minor differences that I'm stumbling a bit

2015-09-13T01:31:04 < zyp> hmm, wonder how the fuck you're supposed to use nrf51's GPIOTE module
2015-09-13T01:32:08 < zyp> nrf51 has this cute event/task system, GPIOTE is a glue module that attaches to GPIO pins and gives them in events/out tasks
2015-09-13T01:32:42 < zyp> in is fair enough, it's pretty much a normal external interrupt thing
2015-09-13T01:33:30 < zyp> an out task can either set, clear or toggle a pin

2015-09-13T01:34:18 < zyp> now, here is the silly part; it can only be configured for one of those, and only one task can be attached to each pin
2015-09-13T01:34:48 < zyp> so there's no way to trigger set and clear from different events
2015-09-13T01:35:06 < zyp> (nrf52 fixes this, adds set/clear tasks to each channel)
2015-09-13T01:35:27 < zyp> this is kinda dumb

2015-09-13T01:36:44 < zyp> the timers can only generate events on match, no direct output compare to pin
2015-09-13T01:39:01 < zyp> so if I want to do pwm, I'll have to use two timer channels; one to trigger high, one to trigger low, point both to the same toggle-task, and hope it doesn't go out of sync which would result in an inverted waveform
2015-09-13T01:40:30 < zyp> nrf52 adds another solution for this as well; a separate pwm peripheral
2015-09-13T01:41:17 < upgrdman> re: nrf51, is an "event in" just an exti isr?

2015-09-13T01:42:10 < zyp> upgrdman, it can generate interrupts as well, yes
2015-09-13T01:42:34 < zyp> but mainly it generates events, which can be hooked up to other tasks
2015-09-13T01:42:41 < upgrdman> how else would it do it? you give it a function pointer or something?
2015-09-13T01:43:40 < zyp> it's a hardware thing
2015-09-13T01:45:24 < zyp> I can for instance configure GPIOTE.IN[0] to trigger on P5 high, then configure the peripheral interconnect block to use that event to trigger TIMER0.START

2015-09-13T05:08:25 < dongs> yep
2015-09-13T05:08:31 < dongs> swapped yesterdays crystal to 12mhz and everythign wroks
2015-09-13T05:08:46 < dongs> i think im gonna xray the "12"mhz one and see if it looks different from the real one
2015-09-13T05:08:56 < dongs> 24m xtal should be a lot smaller i guess
2015-09-13T05:09:12 < Sync> doesn't need to be
2015-09-13T05:09:19 < Sync> it can also be thinner
2015-09-13T05:09:22 < dongs> sync, then why are 8mhz ones huge
2015-09-13T05:09:26 < Sync> or cut differently
2015-09-13T05:09:52 < Sync> because that's one way to do it

2015-09-13T05:46:32 < dongs> just select it in debug thing
2015-09-13T05:46:41 < emeb_mac> I tried today w/ MDK 5.16a and it couldn't see the F7
2015-09-13T05:47:06 < dongs> F7 on t he f7disco with lcd?
2015-09-13T05:47:13 < emeb_mac> nah - my own F7 board
2015-09-13T05:47:19 < dongs> well, -disco worked for me
2015-09-13T05:47:21 < dongs> using onboard stlink.
2015-09-13T05:47:27 < dongs> did you upgrade firmware on wahtever stlink youre using?
2015-09-13T05:47:45 < emeb_mac> yeh - latest firmware from the latest ST-Link Util
2015-09-13T05:47:52 < dongs> hmpf
2015-09-13T05:48:00 < emeb_mac> ST-Link Util sees it OK, but not Keil
2015-09-13T05:48:13 < dongs> you didnt select jtag or something by mistake?
2015-09-13T05:48:31 < emeb_mac> hmm... need to check that. don't think so tho
2015-09-13T05:48:34 < dongs> port SW/JTAG under 'settings'
2015-09-13T05:48:38 < emeb_mac> kk
2015-09-13T05:48:43 < dongs> i think it defaults to jtag on stlink

2015-09-13T07:59:13 < PeterM> upgrdman, there are some crazy asss film ones, but they'reusually super low capacitance
2015-09-13T08:01:38 < PeterM> also, for inductors for fucking around with SMPS, i suggest you buy a fistfull of toroids and some magnet wire and make your own
2015-09-13T08:01:40 < PeterM> http://www.aliexpress.com/store/407105
2015-09-13T08:04:13 < emeb_mac> winding toroids is a PITA, but it is a lot cheaper and more flexible.
2015-09-13T08:05:36 < PeterM> its not that much of a PITA... especially for fuckign around
2015-09-13T08:06:20 < emeb_mac> just don't lose count halfway thru a 200-turn wind.
2015-09-13T08:07:30 < PeterM> +/-10% turns is probably fine anyway because you're not perfectly winding it anyway so you're going to have to measure it anyway
2015-09-13T08:09:14 < emeb_mac> place I used to work had an inductor shop where they wound toroids in bulk. The machines that do that are pretty crazy.
2015-09-13T08:12:01 < dongs> analol'g fuckin around
2015-09-13T08:14:26 < emeb_mac> analog rules
2015-09-13T08:14:46 < emeb_mac> if you can't do it with analog it's not worth doing. :P
2015-09-13T08:15:21 < PeterM> emeb_mac, the spinning ring winders?
2015-09-13T08:15:30 < emeb_mac> PeterM: yep
2015-09-13T08:15:48 < PeterM> i've never seen those for small toriods, only for big toroidal transformers
2015-09-13T08:15:54 < emeb_mac> I don't know exactly how those work, but I assume they pre-wind onto the ring the amount needed.
2015-09-13T08:18:27 < emeb_mac> R2COM: super pro RF designer
2015-09-13T08:19:15 < PeterM> but yeah, wind your own toroids for smps prototyping etc - waiting for mouser/digikey/e14 isnt worth
2015-09-13T08:20:34 < PeterM> several dollars and you have stock of a few cores and some wire and 10 mins oytu have your inductor
2015-09-13T08:23:24 < upgrdman> PeterM, how do you pick a toroid material, and how do you determine how much energy it can store?
2015-09-13T08:23:46 < PeterM> upgrdman, math and sim
2015-09-13T08:24:16 < PeterM> no fucking shit?
2015-09-13T08:25:26 < emeb_mac> who needs math? For simulations you just plop models down and push a button on the GUI.
2015-09-13T08:25:38 < upgrdman> how the fuck do you sim a china toroid?

2015-09-13T08:28:29 < PeterM> (which isnt very much)
2015-09-13T08:31:45 < upgrdman> is there a cheat sheet for this sorta shit. i dont even know where to start.
2015-09-13T08:32:28 < upgrdman> something like "this material is good for x-y kHz" and "roughly z joules per cubic centimeter of this material"
2015-09-13T08:33:08 < emeb_mac> upgrdman: there are standard core types for different frequencies & currents
2015-09-13T08:35:00 < emeb_mac> should be easy to find a table for that - Radio Amateur Handbook has all that stuff in it.

2015-09-13T08:59:44 < upgrdman> PeterM, is there any drawback, other than size and cost, for using a way oversides toroid core?
2015-09-13T09:00:16 < upgrdman> like using one of those fist-size cores, for some 5W application :)
2015-09-13T09:04:29 < PeterM> poor coupling, more losses, trouble getting the inductance down (some times you might only need half a turn to get your desired inductance kinda thing)
2015-09-13T09:05:43 < PeterM> oh, and the fact that  your probably soldering a doughnut sized toroid to a few sot 23s
2015-09-13T09:05:50 < upgrdman> ya

2015-09-13T09:09:18 < PeterM> for iron powder toroids you could probably buy it from a hobo who makes it out of ground up car parts and it would probably meet the specs for standard iron powder toroids

2015-09-13T09:10:57 < jpa-> minimizing losses is for the poor people

2015-09-13T10:23:11 < zyp> it happens when the master releases sda just before the slave grabs it to signal an ack
2015-09-13T10:24:21 < Fleck> ohh, I see

2015-09-13T10:25:55 < Fleck> then I don't understand, why PCF8574 ignores data :/
2015-09-13T10:26:42 < zyp> http://bin.jvnv.net/f/sGXj9.png <- you can see the same effect here on every transition between slave and master where both the bit before and after is 0
2015-09-13T10:27:15 < Fleck> 0b10000011 is getting ignored while 0b10001111 seems to be ok!
2015-09-13T10:27:47 < zyp> well, it's acked by the slave
2015-09-13T10:28:40 < Fleck> yep, seems to be, when I disconect PCF, I get NACK on address transfer
2015-09-13T10:29:47 < Fleck> and PCF8574 seems to be primitive device :/

2015-09-13T17:23:21 < dongs> I occasionally shine a flashlight into the roof of my mouth and feel more alert. But I am delivering 1500 lumens to the soft palate. Enough light passes to make things glow red as I illuminate my retinas from the back. And it could be a placebo effect in my application anyway.
2015-09-13T17:23:42 < dongs> gotta try this
2015-09-13T17:26:21 < dongs> which side is teh driver on
2015-09-13T17:27:25 < Steffanx> the one in the white van in on the right, when you look from the front side.
2015-09-13T17:27:51 < dongs> ok so teh car driver is probly ok
2015-09-13T17:27:54 < dongs> just pissed off.
2015-09-13T17:28:09 < dongs> unless you mean car right

2015-09-13T17:31:18 < dongs> ah
2015-09-13T17:31:30 < dongs> def gotta try.
2015-09-13T17:31:35 < dongs> will it help me get more stoned
2015-09-13T17:32:39 < Steffanx> do you grow your own weed dongs?
2015-09-13T17:32:53 < PaulFertser> I thought JP rules regarding weed were rather strict.
2015-09-13T17:33:20 < PaulFertser> But that's based on that incident with McCartney many years ago. Is it different now?

2015-09-13T18:25:26 < zyp> 16:28:22 < dongs> yesterday I had trouble remembering which side of hte road to drive on
2015-09-13T18:25:29 < zyp> haha
2015-09-13T18:27:41 < zyp> I actually find it pretty intuitive to drive in jp even if it's opposite of what I'm used to
2015-09-13T18:27:57 < zyp> the only part I'm confusing is the direction signals and the windscreen wiper
2015-09-13T18:31:04 < Sync> well there are cars that are the same in lhd and rhd
2015-09-13T18:32:41 < zyp> all the ones I've been driving have the handle for the direction signals at the same side as the driver's door and wipers on the opposite side
2015-09-13T18:33:22 < zyp> i.e. left side in lhd cars, right side in rhd cars
2015-09-13T18:35:15 < zyp> and when you're used to operate it with the left hand, it's pretty fucking easy to turn on your wipers when you're driving a rhd car and are going to turn somewhere

2015-09-13T21:46:01 < Tectu> mandatory army service. Requires you to have a rifle with you and even when you finish the mandatory courses you will have to keep the gun at your home until you are like 45 and dismissed (unless you are some super important person)
2015-09-13T21:46:28 < Steffanx> Tectu: didn't do that afaik. .. ?
2015-09-13T21:46:55 < Tectu> a few years ago you even got the amunition with the rifle when you went home
2015-09-13T21:46:57 < Tectu> they stopped doing that
2015-09-13T21:47:06 < Tectu> but it is not really that difficult to come by if you really want to fuck stuff up, of course
2015-09-13T21:47:21 < Tectu> R2COM, pretty sure nope
2015-09-13T21:47:30 < Tectu> R2COM, guns are pretty well regulated
2015-09-13T21:47:49 < Tectu> even if you are a hunter you are just allwed to have a non-automatic waepon
2015-09-13T21:47:56 < Tectu> no guns at all

2015-09-13T21:48:16 < Tectu> it is not like in america where you can walk into a store and order a gun
2015-09-13T21:48:38 < Tectu> even if you run a private detective business it is very hard to get gun clearance
2015-09-13T21:49:16 < Tectu> it was different a few years ago
2015-09-13T21:49:49 < Tectu> back then I was not old/interested enough but there was some new law a few years ago where you had to like get rid of all guns unless you get a special registration of some sort
2015-09-13T21:49:53 < Tectu> but I am not aware of how that works nowdays
2015-09-13T21:50:04 < Tectu> I just know that guns are not something you just have in .ch
2015-09-13T21:50:18 < Tectu> the irony is taht the army guns just lie around at the train station and get forgotten in train etc.
2015-09-13T21:51:03 < Tectu> I am not into that enough to give proper information. I just know that it got way better regulated during the past few days. My uncle was one of the gun persons and he doesn´t have shit anymore
2015-09-13T21:51:44 < Tectu> I don´t care, really
2015-09-13T21:53:05 < Tectu> R2COM, read up the law. I am not enough into that to give accurate information.
2015-09-13T21:53:19 < Tectu> R2COM, I just know for a fact that it is hard to get guns
2015-09-13T21:53:41 < Tectu> and getting the approval to own one is one thing, but being allowed to take it out of your house is another
2015-09-13T21:54:01 < Tectu> another thing I know for sure is that it is strictly forbidden for any citizen to carry a gun in public at all
2015-09-13T21:54:36 < Tectu> when you are a hunter you are required to take your gun from your house to the forest and back again. you are NOT allowed to even go grocery shopping in the same car trip (even when you leave the gun hidden in the trunk)
2015-09-13T21:55:01 < Tectu> and that is for even just hunting rifles which are far away from anything automatic

2015-09-14T02:40:26 < kakimir> help me chose basic wire for dupont connectors
2015-09-14T02:46:04 < kakimir> there is gauges and strandings :/
2015-09-14T02:46:36 < kakimir> and stranded wires can be bigger as gauges are by copper area
2015-09-14T02:46:46 < kakimir> *are
2015-09-14T02:48:19 < upgrdman> uh, go with maybe 22-24awg, stranded?
2015-09-14T02:48:36 < kakimir> and there are murican units involved and i'm tired and and
2015-09-14T02:49:21 < kakimir> would be interesting to be amurican engineer in company that forces imperial units
2015-09-14T02:49:53 < upgrdman> im an american ee. we use metric for ~everything
2015-09-14T02:50:09 < kakimir> sane people do
2015-09-14T02:50:57 < upgrdman> and i've never seen a company that uses imperial unless they have to (to be compat. with something else, or to meet customer requirements)
2015-09-14T02:52:19 < kakimir> mouser sells just 100ft spools
2015-09-14T02:52:38 < kakimir> 5colors it would do 120eur 0% vat
2015-09-14T02:52:50 < kakimir> maybe not
2015-09-14T02:53:04 < kakimir> ebay time
2015-09-14T02:57:02 < kakimir> 24AWG stranded should be on safe side

2015-09-14T03:07:08 < kakimir> strands?
2015-09-14T03:07:09 < upgrdman> if i need <=4, my favorite wire is usb kybd/mouse cable
2015-09-14T03:07:16 < upgrdman> no like sepeate wires

2015-09-14T03:36:53 < kakimir> why 4A upgrdman ?
2015-09-14T03:37:25 < upgrdman> because my 150mA drivers could handle driving my FETs
2015-09-14T03:38:21 < upgrdman> im using some low RdsON, high current TO220s
2015-09-14T03:38:28 < upgrdman> with an input capacitance of almost 10nF
2015-09-14T03:38:34 < kakimir> sounds sweet
2015-09-14T03:38:48 < upgrdman> so rise time was shit. could barely pwm supersonic
2015-09-14T03:39:11 < kakimir> are you going hypersonic with it?
2015-09-14T03:39:14 < upgrdman> that SEPIC i linked last week
2015-09-14T03:39:35 < upgrdman> because sonic pwm to an inductor annoys the fuck out of me?
2015-09-14T03:39:58 < upgrdman> on second thought, maybe a SEPIC that plays the Super Mario Song could have it's uses
2015-09-14T03:40:24 < GargantuaSauce> dont worry, the control loop will probably oscillate at some audible frequency under particular load conditions anyway
2015-09-14T03:40:28 < kakimir> I wonder if ultrasonic switching fucks brains out of dogs and cats
2015-09-14T03:40:36 < kakimir> and bats
2015-09-14T03:41:05 < upgrdman> R2COM, i plan to drive this at ~100kHz, and make it synchronous     http://www.farrellf.com/temp/sepic_converter_revA.jpg
2015-09-14T03:41:05 < GargantuaSauce> i find those ultrasonic rodent repellers really fucking annoying
2015-09-14T03:41:14 < GargantuaSauce> cant hear the tone but it's modulated at 120hz
2015-09-14T03:41:29 < upgrdman> GargantuaSauce, well i did a boost converter at like 50kHz and couldn't heat shit with a 80W load on it
2015-09-14T03:41:46 < GargantuaSauce> i love you capacitor family
2015-09-14T03:41:50 < upgrdman> and i can hear a little past 19kHz
2015-09-14T03:42:03 < upgrdman> GargantuaSauce, ya i know... i didnt have any high voltage caps laying around.
2015-09-14T03:42:10 < upgrdman> so i pulled those from a CRT monitor PCB
2015-09-14T03:42:13 < kakimir> do you have like goals another than learning?
2015-09-14T03:42:19 < upgrdman> hench shit output caps, but nichicon input cap :)
2015-09-14T03:42:23 < kakimir> performancewise
2015-09-14T03:42:52 < upgrdman> kakimir, not really. it'd be nice if i could do 100W, and go from 0 to 20V with 5V input. not sure how realistic that is.

2015-09-14T03:45:12 < upgrdman> i still need to get bluetooth going on it.
2015-09-14T03:45:34 < upgrdman> R2COM, giving me a more intuitive feel for inductors and caps.
2015-09-14T03:46:05 < upgrdman> and i can see myself wants a SMPS that can go above or below the input voltage
2015-09-14T03:46:16 < upgrdman> and SEPIC was the easier next choice, since i've done a boost
2015-09-14T03:46:24 < kakimir> nice telemetry software you have there
2015-09-14T03:46:28 < upgrdman> plan to try Cúk next
2015-09-14T03:46:35 < kakimir> almost makes me cry
2015-09-14T03:46:41 < upgrdman> kakimir, thx
2015-09-14T03:46:44 < upgrdman> why?
2015-09-14T03:47:09 < kakimir> it's beautyful
2015-09-14T03:47:45 < upgrdman> the code isn't :)
2015-09-14T03:47:56 < upgrdman> but ya, it fucking works. so yay for me.
2015-09-14T03:48:01 < kakimir> wait sliders are used for jerking :x
2015-09-14T03:48:26 < upgrdman> sliders show live view of data points. line graphs can be pop'd up for any data point(s)
2015-09-14T03:48:53 < kakimir> can you move sliders with pointer?
2015-09-14T03:49:37 < kakimir> those should be like grayed out to indicate no pointer action on it
2015-09-14T03:49:51 < kakimir> but less visible
2015-09-14T03:49:58 < yan_> hm anyone know why $sp would be initialized with 0xe0042300 instead of the first value in the vector table?
2015-09-14T03:50:20 < yan_> (stm32l1, cortex m3)
2015-09-14T03:50:32 < upgrdman> kakimir, i didnt disable them because i didn't want them desaturated.
2015-09-14T03:50:50 < upgrdman> so yes you can click and drag them, but the next update... in like 1ms... will redraw it correctly.
2015-09-14T03:51:25 < upgrdman> yan_, no idea. but i would be tempted to comb through the linker script
2015-09-14T03:52:12 < yan_> upgrdman: i tried to and it looks fine; it's the unchanged libopencm3 script.. starts with 'SECTIONS { .text : { *(.vectors) ....'
2015-09-14T03:52:54 < upgrdman> :( dunno then
2015-09-14T03:53:11 < upgrdman> maybe since step starting at reset?
2015-09-14T03:53:16 < upgrdman> err single step*
2015-09-14T03:53:43 < kakimir> isn't there some gauge widgets in graphics libs?
2015-09-14T03:53:55 < yan_> upgrdman: yep, that's how i arrived that it was set incorrectly.. as soon as reset_handler is hit, i dump registers
2015-09-14T03:54:09 < yan_> and then it executes okay until it needs to call a func (i.e. use the stack) it hard faults
2015-09-14T03:54:23 < upgrdman> yan_, this is beyond my knownledge. maybe someone more pro can chime in.
2015-09-14T03:54:56 < upgrdman> kakimir, i looked into it, and sorta said "fuck it. i can just nig rig it in less time that it would take to learn a proper lib"
2015-09-14T03:55:13 < upgrdman> i have since found a very line graph/chart lib, but it doesnt have gauges.
2015-09-14T03:55:25 < kakimir> yes
2015-09-14T03:55:44 < upgrdman> but line graph, bar graphs, histograms, lollipop charts... i can now do with a nice lib
2015-09-14T03:56:13 < upgrdman> i wrote some app for work that did roll-mode-oscope type of line graph, FFTs, and voltage histograms
2015-09-14T03:56:45 < upgrdman> jfreechart, if you use java
2015-09-14T03:56:58 < upgrdman> pretty easy to use once you get past a bit of learning curve
2015-09-14T03:57:09 < upgrdman> makes charts that look like office/excel style
2015-09-14T03:57:17 < yan_> huh well i'll be damned, i have two dev boards.. one of them starts just fine, the other one starts with incorrect sp

2015-09-14T05:47:43 < dongs> haha
2015-09-14T05:48:12 < dongs> i dont wanna "upgrade" from altidong to allegro
2015-09-14T05:48:24 < dongs> o wait
2015-09-14T05:48:44 < dongs> yes, but it only reads .alg files
2015-09-14T05:48:45 < dongs> the ascii shit
2015-09-14T05:48:48 < dongs> that altidong exporter makes
2015-09-14T05:49:12 < dongs> thats ok tho I forgot i grabbed 16.6 back in march, im gonna stick that trash on a vm
2015-09-14T05:49:22 < dongs> yes
2015-09-14T05:49:32 < dongs> An Altium Designer workstation that does not have a licensed Allegro installation is able to import Allegro ASCII Extract files (*.alg). The following procedure enables a Licensed Allegro user to convert Allegro binary *.brd files to Altium compatible *.alg files. The conversion must be run on the Allegro licensed machine.
2015-09-14T05:49:49 < dongs> near bottom of paeg
2015-09-14T05:50:03 < dongs> i think .brd import works if you have alleglol installed side by side
2015-09-14T05:50:13 < dongs> otherwise they make you run the batch shit on allegro machine
2015-09-14T05:50:30 < dongs> haha.
2015-09-14T05:50:43 < dongs> only if you wanna do anything useful
2015-09-14T05:50:48 < dongs> then you still need altium
2015-09-14T05:51:18 < dongs> you should
2015-09-14T05:51:19 < dongs> a2a.zip
2015-09-14T05:51:42 < dongs> and "USING ASCII CONVERSION TO IMPORT WITHOUT ALLEGRO" from that url you have
2015-09-14T05:51:53 < dongs> you'll need open command prompt where allegro shit is in path
2015-09-14T05:54:34 < dongs> attn R2COM / ds2 http://www.altium.com/switch-to-altium-designer-0/

2015-09-14T06:03:04 < dongs> i forgot to restart altidong
2015-09-14T06:03:06 < dongs> i bet it will crash
2015-09-14T06:03:08 < dongs> like last time
2015-09-14T06:05:28 < dongs> neat.. its broken out using 10/20 vias

2015-09-14T07:46:35 < dongs> from like 2011
2015-09-14T07:47:11 < upgrdman> "tented" vias means covered in solder mask, right?
2015-09-14T07:47:16 < dongs> yes
2015-09-14T07:47:32 < upgrdman> why might you want to tent or not tent? other than to make it easy to probe your circuit
2015-09-14T07:47:32 < dongs> but
2015-09-14T07:47:46 < dongs> could also refer to actually really plugging them w/copper
2015-09-14T07:47:49 < dongs> upgrdman: that
2015-09-14T07:47:55 < dongs> and you dont want untented vias under BGA
2015-09-14T07:48:13 < upgrdman> k
2015-09-14T07:48:51 < upgrdman> like why is this ground stitching not tented?  https://hackadaycom.files.wordpress.com/2015/09/simain.png?w=1600

2015-09-14T08:08:42 < dongs> after that cock massage
2015-09-14T08:08:50 < upgrdman> when i reg'd for an altium trial with my work email, the altium faggots called my cell phone like 4 times a week for about 5 weeks.
2015-09-14T08:08:58 < dongs> haha
2015-09-14T08:09:04 < upgrdman> never do that again.
2015-09-14T08:09:28 < upgrdman> next time i use the work number. i didn't use it because i didn't want to bother looking it up when reg'ing for the demo
2015-09-14T08:10:03 < upgrdman> they finally stopped calling me when my boss added me to the license pool
2015-09-14T08:11:06 < upgrdman> prolly
2015-09-14T08:11:18 < upgrdman> the first time they called i answered my phone.
2015-09-14T08:11:30 < upgrdman> dude sounded like he wanted to be the father of my children or someshit
2015-09-14T08:13:15 < talsit> how do you get altium to force complete tenting by default??
2015-09-14T08:14:51 < dongs> talsit: you dont, use pcb inspector to selct allvias and tent them
2015-09-14T08:14:58 < dongs> then make a new template in your lib w/tented stuff and use  those
2015-09-14T08:15:45 < talsit> right, cheers
2015-09-14T08:16:00 < dongs> 15,1 added some via template stuff
2015-09-14T08:16:02 < dongs> its been buggy tho
2015-09-14T08:16:19 < dongs> so i usually just select all after finishing design to amke sure they're all tented
2015-09-14T08:16:48 < ds2> tenting is so easy with Eagle :P

2015-09-14T08:34:51 < upgrdman> so for use nmos for high side switching, its common to use a diode/capacitor charge pump to feed the gate driver. but that wouldn't work to replace D1 in this circuit with an nmos right, since the source of the nmos wouldn't really be changing in voltage very much?  http://www.mouser.com/images/microsites/TI-Bourns-Sepic.png
2015-09-14T08:35:00 < hesperaux> ds2, I understand why it raises suspicion, but it doesn't automatically mean it is spyware
2015-09-14T08:35:22 < ds2> hesperaux: I consider logging usage information to be spyware.
2015-09-14T08:35:29 < hesperaux> the online features of the program are to retrieve models from the repo
2015-09-14T08:35:41 < ds2> hesperaux: you have to get the "licenses"
2015-09-14T08:36:04 < ds2> try doing a brand new install on a system that is never connected online
2015-09-14T08:36:17 < hesperaux> ds2, do you use windows or linux?
2015-09-14T08:36:43 < ds2> hesperaux: windows is not allowed online. Linux is not a stock install.
2015-09-14T08:37:00 < hesperaux> i see
2015-09-14T08:37:04 < dongs> ds2, what the fuck actually. are you paranoid or something
2015-09-14T08:37:16 < hesperaux> lol
2015-09-14T08:37:20 < hesperaux> i thought I was paranoid
2015-09-14T08:37:23 < ds2> :)
2015-09-14T08:37:35 < ds2> if they want my information, they need to be upfront and pay me for it
2015-09-14T08:37:48 < ds2> I refuse to feed their habits
2015-09-14T08:37:56 < hesperaux> how would they contact you ds2? :)
2015-09-14T08:38:09 < ds2> they don't contact me. I contact them :P
2015-09-14T08:38:21 < hesperaux> goodnight R2COM
2015-09-14T08:38:28 < hesperaux> very well
2015-09-14T08:38:40 < ds2> not a fan of "sales"
2015-09-14T08:38:53 < hesperaux> anyway, what do you guys use for stm32 development?
2015-09-14T08:39:07 < ds2> gcc
2015-09-14T08:39:19 < hesperaux> what, with make or something?
2015-09-14T08:39:25 < ds2> of course
2015-09-14T08:39:27 < hesperaux> ok
2015-09-14T08:39:52 < dongs> http://blog.circuitmaker.com/#Blogs/octopart-and-circuitmaker
2015-09-14T08:40:23 < dongs> As I am writing this blog post, work is under way to bring Octopart back into CircuitMaker as the primary component database. Ciiva links will remain in the existing component and design revisions, but we.re going to create updated versions of all the components with their matching Octopart links as well.
2015-09-14T08:40:28 < dongs> loool
2015-09-14T08:40:29 < dongs> make up your fucking mind
2015-09-14T08:42:17 < hesperaux> dongs, is circuitmaker shit?
2015-09-14T08:42:35 < dongs> absolutely
2015-09-14T08:42:43 < dongs> their biggest problem was going with ribbon
2015-09-14T08:42:47 < zyp> probably depends what you compare it to
2015-09-14T08:42:48 < dongs> and removing altium keyboard shortcuts
2015-09-14T08:42:51 < dongs> instead of just making gimped altium
2015-09-14T08:43:04 < dongs> zyp, true
2015-09-14T08:43:51 < hesperaux> ribbon?
2015-09-14T08:44:03 < hesperaux> the UI design pattern used in MS Office?
2015-09-14T08:44:10 < dongs> right
2015-09-14T08:44:16 < hesperaux> gotcha
2015-09-14T08:44:36 < hesperaux> is the model database actually good?
2015-09-14T08:44:45 < dongs> ciiva? i duno, I draw my own components
2015-09-14T08:44:50 < dongs> i did steal STM32F407 from ciiva
2015-09-14T08:44:50 < hesperaux> i haven't found a PCB tool yet that is free and also has parts I need
2015-09-14T08:44:55 < dongs> just so i didnt have to redraw it
2015-09-14T08:45:03 < dongs> but thats rare
2015-09-14T08:45:08 < dongs> all my current library is my own drawn stuff
2015-09-14T08:45:10 < zyp> hesperaux, «has parts»?
2015-09-14T08:45:16 < ds2> does circuitmaker still have STEP output?
2015-09-14T08:45:19 < dongs> zxyp, i think he means library wiht o9k parts in it
2015-09-14T08:45:25 < dongs> ds2: hm, i think it does
2015-09-14T08:45:37 < hesperaux> well, last week I had to make a part for the DRV8301
2015-09-14T08:45:37 < dongs> lemme load this trash up
2015-09-14T08:45:38 < dongs> and see
2015-09-14T08:45:38 < ds2> so it is not that stripped
2015-09-14T08:45:47 < hesperaux> had to make one for AD8237
2015-09-14T08:45:52 < dongs> hesperaux: er and
2015-09-14T08:45:56 < zyp> hesperaux, sure? when I design boards I make all parts
2015-09-14T08:45:59 < hesperaux> and STM32F303
2015-09-14T08:46:21 < hesperaux> that's why I never finish - takes a long time to do that stuff and I'm lazy
2015-09-14T08:46:43 < dongs> get a new hobby, rly
2015-09-14T08:46:51 < dongs> collect animu or somethin
2015-09-14T08:46:53 < dongs> that doesnt take effort
2015-09-14T08:46:58 < zyp> well, in that case the problem is not that you're not using tools without a lot of parts, you're using tools that doesn't make it easy to make parts
2015-09-14T08:46:59 < hesperaux> i do lots of things that take effort
2015-09-14T08:47:23 < hesperaux> zyp, that's possible. So far, DesignSpark seems to be the easiest tool I've used for making parts
2015-09-14T08:47:38 < dongs> ds2: confirmed
2015-09-14T08:47:40 < dongs> has step output
2015-09-14T08:47:41 < dongs> for pcb
2015-09-14T08:47:49 < dongs> and i guess there's 3d models in the circuitdonger db
2015-09-14T08:47:56 < dongs> i dont have any real PCB in it to try
2015-09-14T08:48:04 < dongs> since i just use it for random dicking around cuz lack of keyboard shortcuts pisses me off
2015-09-14T08:48:08 < hesperaux> the problem tends to be that I have too many hobbies, though
2015-09-14T08:48:33 < ds2> does altium have a command line thesedays?
2015-09-14T08:48:48 < zyp> not that I've seen
2015-09-14T08:48:58 < dongs> why would you even need one
2015-09-14T08:49:02 < dongs> command line sounds like some eagle crap
2015-09-14T08:49:04 < zyp> but the hotkeys mostly make up for it
2015-09-14T08:49:06 < ds2> blah that is a performance hinderence
2015-09-14T08:49:12 < dongs> performance hindrance for what
2015-09-14T08:49:13 < ds2> cuz sometimes it is easier
2015-09-14T08:49:16 < dongs> to do what
2015-09-14T08:49:18 < dongs> example
2015-09-14T08:49:19 < ds2> like doing a find by component id
2015-09-14T08:49:24 < dongs> there's that
2015-09-14T08:49:25 < zyp> and yeah, I liked the eagle command line
2015-09-14T08:49:32 < dongs> you can find by component iD.
2015-09-14T08:49:37 < dongs> nexat?
2015-09-14T08:49:39 < dongs> next?
2015-09-14T08:50:06 < ds2> deleting only specific components by id
2015-09-14T08:50:14 < dongs> ?
2015-09-14T08:50:17 < zyp> also, the inspector thing that altium has (hit F11) is more powerful than anything eagle has
2015-09-14T08:50:23 < dongs> ^ this
2015-09-14T08:52:12 < zyp> and if you want to set parameters on commands, like «via gnd» in eagle, you just select the via command, hit tab to get the parameters dialog, pick the gnd net
2015-09-14T08:52:33 < dongs> (and you can still navigate teh dialog wiht keyboard mostly, so mouse is rarely involved)
2015-09-14T08:52:42 < zyp> yes
2015-09-14T08:52:43 < dongs> tab/shfit-tab
2015-09-14T08:55:09 < ds2> in Altium, how does one move a trace X mils over ?
2015-09-14T08:55:50 < dongs> select, ctrl+arrows for grid, or emm+jl to new location
2015-09-14T08:56:10 < dongs> (i asked about relative jump in jl for a similar thing few days ago)
2015-09-14T08:56:17 < ds2> you can't type in exactly how many mils to move?
2015-09-14T08:56:19 < dongs> i think one of edit->move things has offset
2015-09-14T08:56:20 < dongs> you can
2015-09-14T08:56:25 < dongs> jl = jump location
2015-09-14T08:56:30 < ds2> ah
2015-09-14T08:56:40 < ds2> so not as bad as some mcad
2015-09-14T08:56:41 < dongs> o yea
2015-09-14T08:56:44 < dongs> you can move by offset xy
2015-09-14T08:56:59 < ds2> i have having to setup constraints to move things in mcad

2015-09-14T08:58:07 < ds2> i hate
2015-09-14T08:58:10 < dongs> anyway, yeah, edit->move->selection by xy, which can be a track or part or wahtever.
2015-09-14T08:58:22 < dongs> and xy is offset from current location.
2015-09-14T08:58:51 < dongs> i shoulda said that from beginning, cuz i use that a lot when aligning pads in shitty components that don't provide all dimensions on footprint
2015-09-14T08:59:11 < dongs> the thing that rages me the most is when they give distance between component pad EDGES
2015-09-14T08:59:15 < dongs> isntead of center
2015-09-14T08:59:38 < dongs> cuz then I have to bust out calc.exe and /2 the dimension and calculate where it should really be

2015-09-14T09:05:17 < dongs> the worst thing is probly eco scrolling by at like 1 line/second
2015-09-14T09:05:22 < dongs> when you import a large shcmeatic into pcb
2015-09-14T09:05:27 < ds2> yes, it is very annoying
2015-09-14T09:05:32 < dongs> but i think its actually gotten better in that regard
2015-09-14T09:05:45 < ds2> i have a seperate calc when doing parts
2015-09-14T09:05:53 < dongs> yeah
2015-09-14T09:06:06 < dongs> you almost need a desktop calculator unless you wanna break from your current work and do somethign
2015-09-14T09:06:13 < dongs> ;d
2015-09-14T09:06:49 < ds2> cad packages that let me enter equations would be major plus
2015-09-14T09:06:59 < ds2> ecad don't seemto allow that but mcad does
2015-09-14T09:07:14 < dongs> wat is m cad
2015-09-14T09:07:20 < ds2> mechanical cad
2015-09-14T09:07:32 < dongs> o, just general term k
2015-09-14T09:07:36 < ds2> like solidworks, pro-e, autocad, etc
2015-09-14T09:07:41 < ds2> vs electrical cad
2015-09-14T09:07:46 < dongs> rite

2015-09-14T11:31:30 < dongs> good
2015-09-14T11:32:06 < dongs> http://i.imgur.com/6jqfv3q.jpg check out 3d printer trash i saw in best korea
2015-09-14T11:33:48 < PeterM> nice, that actually loks useable unlike most 3d mess makers
2015-09-14T11:34:07 < dongs> ya. to bad its gipsum based so its brittle
2015-09-14T11:34:33 < dongs> but ok for pro
2015-09-14T11:34:36 < dongs> 3d show
2015-09-14T11:34:49 < PeterM> aww :( but gypsum is pretty heat resistant no? so you could make a mold with it, no?
2015-09-14T11:35:00 < dongs> yep definitely
2015-09-14T11:38:27 < jpa-> gypsum may be heat resistent, but isn't there a polymer-based binder there?
2015-09-14T11:38:51 < jpa-> IMO the gypsum prints are useless for anything except "i have to see what this will look like"
2015-09-14T11:39:28 < dongs> tell that to the dicks who dropped 70k on that printer

2015-09-14T13:03:20 < dongs> galileo has gen1/gen2 afaik, i duno about edison, i think theres only one version?

2015-09-14T13:04:22 < dongs> like, im sure that atom has mipi dsi or csi
2015-09-14T13:04:26 < dongs> but its not brken out
2015-09-14T13:04:32 < dongs> the edison one
2015-09-14T13:05:13 < dongs> hgm yeah theres like 2-3 versionf of edison

2015-09-14T14:49:59 < timemob> ok dumb question time
2015-09-14T14:50:31 < timemob> if I have diode in reverse will I still see vcc measuring it, just very low current?
2015-09-14T14:50:47 < timemob> or vcc-vdrop that is
2015-09-14T14:52:29 < timemob> I should probably go to that falstad site
2015-09-14T14:54:57 < jpa-> not vdrop, but a different drop
2015-09-14T14:55:35 < jpa-> for example 1n4148 gives reverse current as 2nA when reverse voltage is 2V
2015-09-14T14:56:19 < jpa-> when reverse voltage is 10V, it rises to 6nA, etc.
2015-09-14T14:56:42 < jpa-> so the drop varies on how much current your meter draws
2015-09-14T14:57:02 < timemob> well if I have say 12v and a shottky in reverse
2015-09-14T14:57:20 < timemob> I will still see ~11v out, just super low current?
2015-09-14T14:58:02 < timemob> meter will show something?
2015-09-14T14:59:33 < timemob> lol falstad is useless on mobile
2015-09-14T14:59:44 < timemob> can't drag parts around
2015-09-14T15:02:12 < mtbg> I'm pretty sure voltage drop becomes arbitrarily close to 0 at low currents
2015-09-14T15:02:44 < timemob> you mean the resulting voltage
2015-09-14T15:02:53 < timemob> not the drop

2015-09-14T16:46:25 < Tectu> wut, is there an image how they remove the labeling of a chip?!  http://www.ebay.com/itm/CNC-3020-800W-Grind-Machine-Milling-Engraving-Machine-for-iPhone-Board-Repair-/321713165138?hash=item4ae7995352

2015-09-14T16:46:37 < Tectu> hey Fleck! I am fine, man. how are you?
2015-09-14T16:46:57 < Tectu> jpa-, what is wolfmanjmware referring to?
2015-09-14T16:47:00 < englishman> im liking lunixcnc
2015-09-14T16:47:01 < jpa-> smoothieware
2015-09-14T16:47:17 < dongs> haha w
2015-09-14T16:47:18 < dongs> what
2015-09-14T16:47:21 < dongs> why is that ebay auction
2015-09-14T16:47:25 < dongs> has specific shit for itrash
2015-09-14T16:47:32 < dongs> for milling chips off of the pcb or something?!
2015-09-14T16:47:40 < Fleck> Tectu: great, thanks! :D
2015-09-14T16:47:49 < Tectu> dongs, that´s what I thought
2015-09-14T16:48:00 < jpa-> Tectu: wolfmanjm was mean to me on the internet so now i bash him together with dongs   https://github.com/Smoothieware/Smoothieware/pull/632#issuecomment-78001722
2015-09-14T16:48:18 < Tectu> dongs, I guess you can´t do it with samsung chips
2015-09-14T16:48:31 < dongs> jpa-: there was somethign else recently
2015-09-14T16:48:39 < dongs> my 3d dicker pal was looking into how z-axis leveling is done
2015-09-14T16:48:41 < dongs> and its like
2015-09-14T16:48:46 < dongs> while (1) { step; check }
2015-09-14T16:48:55 < dongs> so pro!!!111
2015-09-14T16:49:08 < jpa-> well, how else? :)
2015-09-14T16:49:21 < jpa-> the LPC1768 doesn't even allow interrupts on most pins
2015-09-14T16:49:24 < dongs> er, i duno, something proper? dont they have threads or interrupts or something that makes sense
2015-09-14T16:49:25 < Ecco> yeah, it's not like it can do a dichotomy
2015-09-14T16:49:32 < dongs> heh, aids
2015-09-14T16:49:33 < Ecco> oh, ok :)
2015-09-14T16:50:06 < jpa-> they don't have real threads, but it has an event scheduler that runs every 1 millisecond or something and executes stuff in interrupt context
2015-09-14T16:50:28 < Tectu> jpa-, whoops :/
2015-09-14T16:50:32 < jpa-> also: they have no mutexes or anything like that, it's thread safe by just being lucky
2015-09-14T16:50:43 < Tectu> jpa-, is that guy taking IRC conversations into github pull requests?
2015-09-14T16:50:45 < dongs> jpa, but they're using std::atomic
2015-09-14T16:50:47 < dongs> and osme other trash
2015-09-14T16:50:52 < dongs> from c=+112
2015-09-14T16:50:56 < dongs> so that makes them super pro
2015-09-14T16:50:58 < dongs> !!11
2015-09-14T16:51:08 < jpa-> :)
2015-09-14T16:51:21 < mtbg> they don't implement anything to preserve data integrity?
2015-09-14T16:52:17 < jpa-> mtbg: they have some things on case-by-case basis
2015-09-14T16:53:45 < jpa-> though i can kind of understand going for a lockfree design for a realtime thingy
2015-09-14T16:53:56 < jpa-> just seems that it is not done very carefully here
2015-09-14T16:54:15 < mtbg> mutexes in interrupt context would not work, except some _trylock(...)
2015-09-14T16:54:49 < Tectu> jpa-, did you take a look at ShapeOko before you bough the CNC3020?
2015-09-14T16:54:50 < mtbg> normal approach is to turn off interrupts if you can't do it atomically
2015-09-14T16:55:13 < jpa-> Tectu: yeah, seemed crappier and more expensive
2015-09-14T16:55:46 < jpa-> openness is nice, but on the commodity hardware is pretty open by itself
2015-09-14T16:55:52 < jpa-> *on the other hand
2015-09-14T16:55:58 < dongs> huh
2015-09-14T16:56:04 < dongs> whyt the fuck is boot0 on  F4-disco pulled up to vdd
2015-09-14T16:56:10 < Tectu> jpa-, 400$ shipping to europe???? (on the sapeoko 3 page for preordering(
2015-09-14T16:56:14 < jpa-> like if i break a bearing on the cnc3020, ebay is full of them
2015-09-14T16:56:31 < englishman> shapeoko looks mega crap
2015-09-14T16:56:33 < jpa-> Tectu: yeah, cnc3020 from china was 200EUR
2015-09-14T16:56:34 < englishman> belts on cnc??? lol
2015-09-14T16:56:49 < dongs> polol@you
2015-09-14T16:56:53 < Tectu> jpa-, 200 EUR sounds reasonable. 400 seems crazy
2015-09-14T16:56:58 < dongs> i wish i had time for a fucking cnc
2015-09-14T16:57:05 < dongs> or skills to acutally design something TO CNC
2015-09-14T16:57:09 < Tectu> stfu, you have a pick-n-place man
2015-09-14T16:57:20 < dongs> yeah how is taht even remotely related
2015-09-14T16:57:23 < englishman> yeah just attach endmill to picknplace
2015-09-14T16:57:29 < dongs> right lemme get right on that
2015-09-14T16:57:30 < Tectu> LOL!
2015-09-14T16:57:35 < jpa-> you can pick and place tiny bits of metal and melt them together
2015-09-14T16:57:52 < zyp> metal 3d printer!
2015-09-14T16:58:48 < jpa-> Tectu: regarding the ebay listing above, seems they are not just removing the label but removing the entire chip, easier than desoldering apparently
2015-09-14T16:59:09 < dongs> its like the xbox re-reflow all over again
2015-09-14T16:59:20 < dongs> what are they removing anway
2015-09-14T16:59:22 < dongs> emmc or something?
2015-09-14T16:59:32 < jpa-> some iphone chips apparently
2015-09-14T16:59:42 < dongs> does it make it go faster
2015-09-14T17:00:01 < Ecco> why would they remove emmc?
2015-09-14T17:00:05 < zyp> maybe they just make holes in the chip for airflow, so it doesn't get so hot!
2015-09-14T17:00:30 < Tectu> jpa-, interesting, but I´d be afraid of ripping of a pad
2015-09-14T17:00:31 < dongs> ecco, to turn 16gb itrash into 64gb itrash
2015-09-14T17:00:33 < dongs> for less than $200

2015-09-14T17:00:53 < Ecco> oooooh
2015-09-14T17:00:53 < Tectu> your soul
2015-09-14T17:00:59 < Ecco> that's actually pretty smart
2015-09-14T17:01:21 < Ecco> I wonder if there's something in the iOS software that would check for this
2015-09-14T17:01:30 < jpa-> Tectu: well, it's probably BGAs anyway so there is quite a thick amount of solder between the chip and the pad
2015-09-14T17:02:02 < Tectu> jpa-, well, I was not afraid of milling too deep but that that the solder pulls on the pad as it is getting milled away
2015-09-14T17:02:29 < dongs> duno man they're selling that means:
2015-09-14T17:02:32 < dongs> obviosuly thery've figured that part out
2015-09-14T17:02:37 < dongs> china is not liike a dickstarter
2015-09-14T17:02:41 < dongs> where you sell, then figure out how it works
2015-09-14T17:02:42 < kakimir> apparently routers can het hijacked
2015-09-14T17:02:55 < jpa-> Tectu: yeah, but milling just the chip away is enough.. solder can be removed by heating
2015-09-14T17:03:02 < kakimir> https://drive.google.com/file/d/0B2GcdpJiNGfKM1lMVXV5eExiWDg/view?usp=sharing
2015-09-14T17:03:19 < Tectu> jpa-, indeed
2015-09-14T17:03:21 < jpa-> Tectu: so one just hopes that chip -> solder is not much stronger than solder -> pad or pad -> pcb
2015-09-14T17:03:58 < Tectu> jpa-, that was the part I was unsure about, how much hope actually is needed for that
2015-09-14T17:04:06 < jpa-> probably not much
2015-09-14T17:04:16 < jpa-> but dunno
2015-09-14T17:04:43 < dongs> <zano> Based off the updates from the message boards and a reply to a contact request I was told I'll have one by the 18th. Luckily I preordered black just after the kickstarter campaign closed out and they've started fulfilling those to the US!

2015-09-14T17:29:39 < dongs> any idea what STM32 internal temperature sensor measurement range is

2015-09-14T17:29:55 < dongs> i guess ill check datasheet
2015-09-14T17:30:08 < dongs> range is between 1.8 and 3.3V
2015-09-14T17:32:36 < jpa-> did it need calibration or some shit like that
2015-09-14T17:32:44 < jpa-> i once tried to use it on stm32l151 and it sucked

2015-09-14T17:33:02 < dongs> im guessing one can linear-fit stuff in bettwene there
2015-09-14T17:34:52 < jpa-> yeah, that's the idea
2015-09-14T17:34:58 < jpa-> actual accuracy seemed quite poor
2015-09-14T17:36:11 < jpa-> though i had extra trouble due to box isolating it from what i actually wanted to measure
2015-09-14T17:36:50 < jpa-> https://svn.kapsi.fi/jpa/doglight2/sw/src/stm32l_adc.c   looks like my code considers the other calibration value as 25 celcius instead of 30..
2015-09-14T17:37:04 < dongs> 25C is the correct offset
2015-09-14T17:37:08 < dongs> thats not related to ts1/2
2015-09-14T17:37:42 < jpa-> yeah i have offset of 25C also

2015-09-15T05:07:22 < dongs> no zoom etc. it does have autofocus apparently
2015-09-15T05:08:00 < GargantuaSauce> the soc supports autofocus but it requires fancier optics
2015-09-15T05:08:14 < dongs> well, it has that
2015-09-15T05:08:26 < dongs> i mean, the module supports AF

2015-09-15T09:34:12 < emeb_mac> dongs: the F4 DAC has a range of about VDD - 3.3V. That's slightly more than line level.
2015-09-15T09:35:05 < dongs> is that good or bad
2015-09-15T09:35:18 < emeb_mac> but "decent-ish" depends - do you want lowpass filtering? What's your sample rate? What levels do you want?
2015-09-15T09:35:20 < dongs> maybe i should just add like a speaker amp
2015-09-15T09:35:35 < dongs> emeb_mac: mono speaker
2015-09-15T09:35:37 < dongs> like 11khz sample rate
2015-09-15T09:35:41 < dongs> or 22k max
2015-09-15T09:35:46 < dongs> lpf I can just make using R+C right?
2015-09-15T09:35:55 < Roklobsta> that's fine
2015-09-15T09:36:15 < Roklobsta> if you make an amp you might as well make it a 2nd order sallen+key type.
2015-09-15T09:36:29 < dongs> no, i want to have as less components as possible
2015-09-15T09:36:37 < Roklobsta> is the output from a dac or pwm?
2015-09-15T09:36:42 < dongs> dac
2015-09-15T09:36:47 < dongs> F4's dac_out thing
2015-09-15T09:36:48 < emeb_mac> dongs: with a 22kHz sample rate you'll have some serious aliasing unless you put a decent high-order lowpass reconstruction filter on it.
2015-09-15T09:37:22 < dongs> how about 11k?
2015-09-15T09:37:31 < Roklobsta> yeah, ok, 1st order RC is fine.  make the 3dB point a bit lower then fs/2
2015-09-15T09:37:33 < Roklobsta> tha
2015-09-15T09:37:34 < emeb_mac> gets worse as sample rate goes down
2015-09-15T09:37:34 < Roklobsta> n
2015-09-15T09:37:54 < dongs> wats a lowpass reconsturciton filter

2015-09-15T09:38:10 < Roklobsta> is it just for the occasional fart alert sound or will it be used a lot?

2015-09-15T09:38:33 < emeb_mac> then you don't need a filter
2015-09-15T09:38:35 < dongs> it shouldnt sound like shit
2015-09-15T09:38:52 < Roklobsta> ok, RC with a 3dB at Fs/2
2015-09-15T09:38:54 < emeb_mac> just put some rolloff in the amp
2015-09-15T09:38:57 < dongs> if i wanted sound like shit I can pickup cinese ADPCM player chip for $0.50
2015-09-15T09:39:26 < Roklobsta> don't forget the usual mid point is 1.5V and capacitively couple the speaker.
2015-09-15T09:39:52 < Roklobsta> er, mid is VDD/2
2015-09-15T09:40:08 < dongs> capacitave couple = just AC couple right? i.e. cap in the line
2015-09-15T09:40:08 < emeb_mac> 1.65 ~= 1.5

2015-09-15T09:42:53 < dongs> ok so
2015-09-15T09:43:02 < dongs> RC filter on dac output
2015-09-15T09:43:06 < dongs> ac couple speaker
2015-09-15T09:43:12 < dongs> that leaves the part about actual amplification
2015-09-15T09:43:21 < dongs> do I need amp or can I just drive shit directyly from dac?
2015-09-15T09:43:46 < Roklobsta> depends on the speaker.  you might need an amp like a shitty lm386
2015-09-15T09:44:07 < dongs> doesnt that need a lot of extra parts
2015-09-15T09:44:09 < Roklobsta> is it piezo style?
2015-09-15T09:44:14 < dongs> nah its coil
2015-09-15T09:44:25 < dongs> or watever, yanno, voice coil + diaphragm
2015-09-15T09:44:30 < Roklobsta> hmmm, should have an amp designed for 8ohm loads

2015-09-15T09:44:50 < Roklobsta> but test the dac, maybe it's ok.
2015-09-15T09:45:14 < Roklobsta> what is the dac output impedance? can it push some hefty current?
2015-09-15T09:46:17 < dongs> there's a buffer that user can on/off in the dac
2015-09-15T09:46:23 < dongs> only shows 15k impedance with that buffer off
2015-09-15T09:46:37 < dongs> 5k resistive load with buffer on
2015-09-15T09:49:27 < Roklobsta> the usual applies, for max power transfer source impedance should match load impedance.
2015-09-15T09:49:55 < Roklobsta> so you might need a simple amp.  so8 style.

2015-09-15T13:04:17 < Mr_Sheesh> Question for you folks; What STM32 discovery board would you run if you need to stay at 5V for the ARM uC's power supply? Hoping to find one that has 1 or 2 DACs on it as well; Should be easier to do this project on an STM32 than an AVR and I don't feel like using a RPi for this...
2015-09-15T13:04:41 < jpa-> there aren't any STM32 that would operate at 5V
2015-09-15T13:04:54 < jpa-> all discovery boards have 3.3V regulator on the board
2015-09-15T13:05:40 < Mr_Sheesh> Aaah; OK. Then which one would you run with, that has a DAC on there? I need to do some audio stuff, mainly lower frequencies, new to STM32s
2015-09-15T13:06:29 < jpa-> audio dac? IIRC those are on the F4 discovery
2015-09-15T13:06:49 < jpa-> most STM32's also have built-in 12 bit 2 channel DAC that is enough for crappy audio
2015-09-15T13:07:11 < Mr_Sheesh> Yeah; I just don't want to mess with an R/2R cheap junk DAC.
2015-09-15T13:07:37 < jubatus> use cheap TDA1541
2015-09-15T13:07:48 < jpa-> yeah, well F4 discovery should work fine; easier to get started with the built-in DAC and you can use the higher-quality I2S DAC chip later if you want

2015-09-15T13:11:52 < Mr_Sheesh> OK, TY, I'll look more in the morning, should be a good option. Lots more CPU speed than an AVR :)

2015-09-15T16:59:03 < emeb> so that plus 3 passive parts hooked to the F4xx DAC output would probably work fine.
2015-09-15T16:59:55 < dongs> emeb: on where? input or output
2015-09-15T17:00:10 < dongs> im gueessing input
2015-09-15T17:01:11 < emeb> F4xx DAC pin - DC blocking cap (0.1-1.0uf) - LPF & Gain resistor - PAM input
2015-09-15T17:01:24 < emeb> then an LPF cap from PAM input to GND
2015-09-15T17:01:47 < dongs> hm thats adding more parts than i really care about
2015-09-15T17:01:53 < dongs> i can understand rc lpf, what about rest of shit?
2015-09-15T17:01:54 < dongs> wahts gain for
2015-09-15T17:02:13 < emeb> DC blocking cap?
2015-09-15T17:02:28 < dongs> no like
2015-09-15T17:02:31 < dongs> i ahve dc cap now
2015-09-15T17:02:38 < dongs> dac -> cap -> pam input

2015-09-15T17:02:55 < dongs> i can add a rc lpf after cap (?or before cap?)
2015-09-15T17:02:59 < dongs> but whats the 'gain resistor' thing?
2015-09-15T17:03:26 < emeb> gain resistor is to control how hard the DAC drives the amp
2015-09-15T17:03:34 -!- intart [~intart@190.167.23.114] has quit [Quit: Leaving]
2015-09-15T17:03:44 < emeb> if DAC full swing overdrives the amp then you lose resolution
2015-09-15T17:03:55 < emeb> so resistor is there to limit gain
2015-09-15T17:04:14 < emeb> DAC gives ~3.3Vpp
2015-09-15T17:04:31 < dongs> but if you turn on buffer
2015-09-15T17:04:35 < dongs> its less
2015-09-15T17:04:40 < emeb> only slightly less
2015-09-15T17:04:47 < emeb> 3.1Vpp maybe
2015-09-15T17:05:08 < dongs> so you think its necesary
2015-09-15T17:05:23 < emeb> you could always just reduce the signal range in DSP
2015-09-15T17:05:38 < emeb> but that cuts resolution and raises noise floor
2015-09-15T17:05:48 < emeb> so it's better to use analog gain -> resistor
2015-09-15T17:06:25 < emeb> But - for minimum parts, just use DC blocking cap and make up for it in software.
2015-09-15T17:06:31 < dongs> yay
2015-09-15T17:07:21 < emeb> If it were me I'd put two more passives in the signal path just for pro / hifi. :)
2015-09-15T17:08:07 < dongs> so R in series and C to gnd right? but thats just LPF?
2015-09-15T17:08:12 < emeb> yes
2015-09-15T17:08:14 < dongs> or do you mean another R after that for gain?
2015-09-15T17:08:17 < emeb> no
2015-09-15T17:08:21 < dongs> just thast?
2015-09-15T17:08:25 < emeb> yes
2015-09-15T17:08:33 < emeb> the PAM input has 10k impedance
2015-09-15T17:08:44 < emeb> so the value of R you use affects gain too
2015-09-15T17:08:48 < dongs> ah right
2015-09-15T17:08:52 < dongs> im looking at some tarduino shit
2015-09-15T17:08:57 < dongs> 1.5k/10nF for 11khz lpf
2015-09-15T17:09:02 < Laurenceb> lol

2015-09-15T17:09:35 < Laurenceb> it was as bullshit as it sounds
2015-09-15T17:09:59 < Laurenceb> what I want to know is why theres always the same people at any bullshit event in the UK
2015-09-15T17:10:22 < dongs> emeb: wait, that RC is before or after ac bias cap
2015-09-15T17:10:32 < emeb> dongs: yes - those values give ~10.6kHz corner freq
2015-09-15T17:10:42 < Laurenceb> Quinetiq etc
2015-09-15T17:10:47 < emeb> and it doesn't matter what order you put them in
2015-09-15T17:11:04 < dongs> mmkay ill do them before
2015-09-15T17:11:06 < emeb> but I'd put DC cap @ F4 output, then R, then C
2015-09-15T17:11:12 < dongs> o okay
2015-09-15T17:11:13 < dongs> then after.
2015-09-15T17:11:37 < emeb> the 1.5k resistor won't affect gain much
2015-09-15T17:11:57 < dongs> i could always replace it wiht 0R
2015-09-15T17:11:59 < dongs> and NP the cap
2015-09-15T17:12:01 < dongs> for max pro
2015-09-15T17:12:02 < emeb> yes
2015-09-15T17:12:03 < dongs> if something isnt working

2015-09-15T17:13:18 < emeb> if you need to cut gain then just multiply R and divide C by same factor to preserve corner freq
2015-09-15T17:13:25 < emeb> (so double R, half C, etc)
2015-09-15T17:15:39 < emeb> (07:09:59 AM) Laurenceb: what I want to know is why theres always the same people at any bullshit event in the UK
2015-09-15T17:15:49 < emeb> because UK is a small place

2015-09-15T21:07:36 < tasslehoff> I'm about to start developing a userspace application in Linux to program an stm32 device over SPI, and it suddenly occured to me that maybe someone has done it before :)
2015-09-15T21:07:47 < tasslehoff> Any available apps/tools/drivers for that?
2015-09-15T21:08:11 < zyp> SPI?
2015-09-15T21:10:10 < tasslehoff> zyp: yes. is that odd?
2015-09-15T21:10:36 < mtbg> built-in bootloader supports uart and sometimes usb
2015-09-15T21:11:24 < zyp> tasslehoff, no, I'm just wondering what you're hooking it up to? something that has a kernel spi driver?
2015-09-15T21:11:49 < zyp> like an ARM SBC or something?
2015-09-15T21:11:50 -!- blight [~greg@reactos/developer/blight] has joined ##stm32
2015-09-15T21:12:20 < zyp> or are you using a different transport layer to some sort of SPI adapter?
2015-09-15T21:12:27 < tasslehoff> it's hooked up through spi (and i2c) to an arm running linux
2015-09-15T21:12:36 < zyp> right ok
2015-09-15T21:13:14 < jpa-> tasslehoff: what is wrong with swd?
2015-09-15T21:13:17 < zyp> how are you putting the device into bootloader mode? do you already have a communication framework that you can utilize?
2015-09-15T21:14:07 < zyp> jpa-, swd is nice for development, but a bit more complex than required for field upgrades
2015-09-15T21:14:14 < jpa-> true
2015-09-15T21:14:25 < jpa-> missed the part about permanently being hooked up
2015-09-15T21:15:07 < tasslehoff> jpa-: permanently hooked up, and communicating on spi/i2c after upgrade as well :)
2015-09-15T21:15:38 < Sync> why not use uart?
2015-09-15T21:16:33 < zyp> tasslehoff, in my bootloader, I have a core with three commands (prepare/write_block/finish), which I can then hook to any packet layer
2015-09-15T21:16:39 < tasslehoff> zyp: currently we are prototyping, and have connected an arm evalboard to an stlink evalboard, so I can but it in bootloader mode manually. I think hw plans to control the boot mode pin from an uC in the end.
2015-09-15T21:17:14 < zyp> I originally hooked it to USB DFU, but I later changed it to USB HID to simplify the host side software
2015-09-15T21:17:24 < tasslehoff> Sync: I don't really know. That decision was not made by me.
2015-09-15T21:17:46 < zyp> so if you already have a packet layer over SPI, I'd suggest just reusing that for transporting a few bootloader packets
2015-09-15T21:18:08 < zyp> with a custom bootloader, of course
2015-09-15T21:18:13 < Sync> because spi just seems strange
2015-09-15T21:18:29 < zyp> Sync, why? spi is perfectly fine
2015-09-15T21:18:48 < Sync> sure, idk, I just never seen somebody do it that waxy
2015-09-15T21:18:51 < Sync> -x
2015-09-15T21:18:55 < tasslehoff> zyp: I've created a loader that upgrades an stm32f4 over i2c, and the change to spi does not seem immense.
2015-09-15T21:19:04 < zyp> shouldn't be
2015-09-15T21:19:11  * tasslehoff was about to google what waxy could mean in this context :D
2015-09-15T21:19:34 < zyp> http://cgit.jvnv.net/arcin/tree/bootloader.cpp#n71 <- here's this core I mentioned
2015-09-15T21:19:39 < zyp> and the HID adapter right below it
2015-09-15T21:21:36 < tasslehoff> hm. that link does not work for me.
2015-09-15T21:21:54 < zyp> strange, it should
2015-09-15T21:22:41 < zyp> maybe your ipv6 setup is broken and doesn't fall back properly to ipv4?
2015-09-15T21:23:55 < tasslehoff> chrome handled it properly. firefox did not
2015-09-15T21:26:39 < zyp> for i2c I would probably have a command register with bits to trigger prepare/finish and a fifo register that feeds into write_block
2015-09-15T21:26:56 < zyp> either way, it's a simple model and easy to map to all sorts of transports
2015-09-15T21:27:59 < tasslehoff> zyp: thanks. I'll take a look at it.
2015-09-15T21:28:38 < zyp> if your protocol doesn't support direct error reporting, you should probably make a third error state so that an error during write_block would keep future writes from happening
2015-09-15T21:29:02 < zyp> in my case I'm returning error codes over usb as soon as an error occurs
2015-09-15T21:30:26 < tasslehoff> zyp: but do I really need a custom bootloader?
2015-09-15T21:30:52 < zyp> I don't know? does the stock one include an SPI mode?
2015-09-15T21:31:46 < tasslehoff> zyp: yes :)
2015-09-15T21:32:36 < zyp> well, if it's appropriate for your application, then I guess it's fine
2015-09-15T21:32:47 < tasslehoff> zyp: I'm fairly happy with the way my i2c loader turned out, so I'll try to adapt that one. I may be back later :)
2015-09-15T21:32:52 < tasslehoff> thanks for sparring
2015-09-15T21:33:02 < zyp> in my case, I could have gone with the USB mode in the built in one,
2015-09-15T21:34:53 < karlp> tasslehoff: you're going to have another uC to control the boot pin of the stm32 uC?

2015-09-15T21:51:27 < tasslehoff> zyp: the product is controlled from the outside, and the uC controls reset on all processors, so it fits in that it controls the boot mode as well.

2015-09-16T00:01:04 < zyp> multiple dies in a single package would be more likely, but still inconvenient
2015-09-16T00:01:20 < zyp> that's why you get PoP packages instead
2015-09-16T00:02:23 < zyp> so you put the memory on top of the cpu, which means you can mix memory and cpu chips as you like, but still get the benefit of not having to route between them on your pcb

2015-09-16T00:18:11 < neuro_sys> zyp: Fleck, right, so peripherals library is a bit high level for that, and I should just modify the registers. zyp: it wasn't SPI, but one-wire protocol, which requires configuring the pin as output and input quickly.
2015-09-16T00:20:12 < zyp> say that then :)
2015-09-16T00:21:02 < zyp> oh, and for one-wire, wouldn't you just want to run the pin in open drain mode?
2015-09-16T00:21:10 < neuro_sys> yeah
2015-09-16T00:21:29 < neuro_sys> so that is not the same as setting the pin as input?
2015-09-16T00:21:35 < zyp> no?
2015-09-16T00:22:03 < neuro_sys> (in pic16, I'd just set it as input, and hey, a fresh noob here)
2015-09-16T00:22:17 < zyp> well, does pic16 even have opendrain? :p
2015-09-16T00:22:40  * neuro_sys looks open drain (open collector?) up.
2015-09-16T00:22:49 < zyp> yeah
2015-09-16T00:23:13 < zyp> collector and drain are analogue terms
2015-09-16T00:23:29 < zyp> a bjt collector is pretty much equivalent to a fet drain
2015-09-16T00:24:23 < neuro_sys> so, if it was an open drain pin, then there'd be no need to set it as output and input constantly, right?
2015-09-16T00:24:38 < neuro_sys> because open drain lets you output a signal, and act as a drain when idle?
2015-09-16T00:25:33 < zyp> open drain means that you disable the high side driver block
2015-09-16T00:25:53 < zyp> so instead of outputting either low or high, the pin would only be outputting low or letting it float
2015-09-16T00:26:20 < zyp> which means that outputting 1 is equivalent to setting the pin in input mode, except you don't have to change modes all the time
2015-09-16T00:26:52 < neuro_sys> yeah got it
2015-09-16T00:26:59 < zyp> also, I don't remember the 1wire protocol in detail now, but IIRC it's timing based
2015-09-16T00:27:13 < neuro_sys> yes
2015-09-16T00:27:29 < zyp> and for timing based protocols, it's often convenient to generate it from a timer in output compare mode, rather than bitbanging it by hand
2015-09-16T00:27:29 < neuro_sys> and it requires a pull-up resistor on the data line
2015-09-16T00:28:30 < zyp> yes, since nobody is driving high
2015-09-16T00:28:41 < zyp> it's common for shared bus protocols, i2c works the same way
2015-09-16T00:29:37 < neuro_sys> the timings are rather irregular, is it still better to do it with timers?
2015-09-16T00:29:52 < neuro_sys> err, or no

2015-09-16T00:32:06 < karlp> bit banging means you can do it on any pin you like though, and it's normally slow enough you don't care anyway.
2015-09-16T00:32:36 < zyp> karlp, like stm32s have any shortage of timer pins :)
2015-09-16T00:32:51 < neuro_sys> there's no clock at all, there's only this timings the slaves expect as far as I understand

2015-09-16T00:33:18 < zyp> well, it's a digital protocol, obviously there's a clock
2015-09-16T00:33:23 < zyp> it's just embedded in the signal

2015-09-16T00:35:50 < zyp> which allows you to do a full transfer with dma, which means the cpu can do other stuff in the mean time
2015-09-16T00:36:13 < karlp> if that's important, yes, you can definitely use it like that :)
2015-09-16T00:37:01 < zyp> for reads you can let CH1 use OC to generate the timing pulses, while CH2 reads back CH1 to grab timings with input capture
2015-09-16T00:37:28 < zyp> assuming, of course, that the slave grabs the data line before the master releases it during the reads, like in the diagrams

2015-09-16T02:03:31 < karlp> [7]: why does your cpp layer do GPIO::setLevel(pin,...) rather than pin.setLevel? it's not even port::setlevel(pin...) but your onewire stuff operates as bus:: and device::, seemed a little odd?

2015-09-16T02:21:16 < dongs> heh
2015-09-16T02:21:32 < dongs> i should order arcin parts and have you pay for them. but dont stay up for that
2015-09-16T02:21:48 < zyp> true, I should also order digikey parts
2015-09-16T02:21:53 < zyp> hmm
2015-09-16T02:22:00 < dongs> ohh
2015-09-16T02:22:02 < dongs> those headers?
2015-09-16T02:22:08 < zyp> yeah
2015-09-16T02:22:33 < zyp> it's still weird that chinagirl can't get those, I see XH used on tons of cheap china shit
2015-09-16T02:22:51 < dongs> i can retry if you get me the spec again
2015-09-16T02:22:59 < dongs> i think the issue last time was the clones/boss stuff
2015-09-16T02:23:11 < dongs> arent the ones you asked had special alignment stuff
2015-09-16T02:24:07 < zyp> well, they have that plastic pin, but the variant without it would obviously fit as well
2015-09-16T02:24:18 < dongs> righto
2015-09-16T02:24:28 < dongs> well, gimme part#s again and  qtys and ill retry
2015-09-16T02:24:36 < dongs> and if not you can order tomrorow
2015-09-16T02:25:31 < zyp> JST-XH, 2 and 4-pin
2015-09-16T02:26:07 < dongs> vertical?
2015-09-16T02:26:16 < zyp> B2B-XH-AM and B4B-XH-AM (or replace -AM with -A for variants without the pin)
2015-09-16T02:26:17 < dongs> and how many of each
2015-09-16T02:26:17 < dongs> ok
2015-09-16T02:26:50 < zyp> 2 two-pin and 13 four-pin per board
2015-09-16T02:27:05 < zyp> IIRC I usually do 250 and 1500 respectively for a batch
2015-09-16T02:27:06 < dongs> and fr4 is 56*2
2015-09-16T02:27:43 < dongs> hm my notes say its 56 sheets w/2 per
2015-09-16T02:27:55 < dongs> were we ordering more than one m^2?
2015-09-16T02:28:05 < zyp> idk?
2015-09-16T02:28:32 < dongs> kk, will confirm later today. cuz m^2 is ordered and it should be 56*2 and there's 7 sheets remaining from previous batch
2015-09-16T02:28:36 < dongs> (unless this info is old
2015-09-16T02:28:37 < zyp> I think I just said I wanted around 100 first time, and that was somehow rounded up to 112, and that's what we've done since
2015-09-16T02:28:52 < dongs> okayh.
2015-09-16T02:29:31 < dongs> so how many is getting assembled?
2015-09-16T02:29:34 < dongs> for parts purposes
2015-09-16T02:29:38 < dongs> all, or still ~100?
2015-09-16T02:29:52 < zyp> uh, the leftover sheets, are they v1.1 or v1.1.1?
2015-09-16T02:31:05 < dongs> how can i check?
2015-09-16T02:31:10 < dongs> is there a versioN# on it?
2015-09-16T02:31:13 < zyp> it's marked on the silk
2015-09-16T02:31:17 < dongs> ok
2015-09-16T02:31:50 < zyp> first four batches were v1.1, fifth were v1.1.1, and I hope you got that right on current as well :p
2015-09-16T02:32:48 < dongs> will check. i have 1.1.1 data from 11/19/2014
2015-09-16T02:33:04 < dongs> camdata from factory.
2015-09-16T02:33:12 < dongs> the leftovers should be latest revision
2015-09-16T02:33:16 < dongs> will know after 9e
2015-09-16T02:33:42 < dongs> go to sleep, will let you know later ;d
2015-09-16T02:33:44 < zyp> okay, if they are v1.1.1 then I guess just assemble them as well
2015-09-16T02:34:45 < zyp> I don't want to deal with distinguishing between them, so I don't want any v1.1 boards assembled

2015-09-16T04:03:22 < dongs> its probly some coil coupling into the input transformer

2015-09-16T04:03:55 < dongs> or pico~
2015-09-16T04:05:21 < aandrew> ok back to basics question on stm32
2015-09-16T04:05:32 < aandrew> with the nvic is it a bad thing to have several interrupts with the same priority?
2015-09-16T04:05:57 < dongs> zyp will know, but they';ll just get handled in order or somethin
2015-09-16T04:06:27 < aandrew> that's kind of what I thought... I have three UARTs, 1,2,6. all are intialized with the same prio
2015-09-16T04:06:58 < aandrew> uart2 is my console port. if I use uart1 things work. if I use uart6 things don't and I can't figure out why
2015-09-16T04:07:15 < dongs> probly not due to pris.
2015-09-16T04:07:53 < aandrew> probably not I agree
2015-09-16T04:07:58 < aandrew> just trying to figure out what the fuck
2015-09-16T04:08:01 < aandrew> this is ridiculous

2015-09-16T04:10:02 < aandrew> I have printf() redirecting to uart2 by writing an __io_putchar() and fputc() that uses it. It just writes to the uart. nothing fancy.
2015-09-16T04:10:19 < aandrew> if I use uart1, my console shit works
2015-09-16T04:10:28 < aandrew> if I use uart6, my console shit doesn't work (nothing output)
2015-09-16T04:10:32 < aandrew> console always on uart2
2015-09-16T04:10:47 < aandrew> all I'm doing in the code is swapping the uart I initialize for the target device (uart1 or uart6)
2015-09-16T04:11:14 < dongs> and you configued AF properly and shit
2015-09-16T04:11:23 < dongs> isnt uart1 a usart and uart6 is uart?
2015-09-16T04:12:39 < dongs> init looks same anyway.
2015-09-16T04:13:28 < dongs> i have code that uses them all (not all enabled at once tho, but soemtimes yes) in dma +irq configurations
2015-09-16T04:13:33 < dongs> and they're all on priority#2
2015-09-16T04:13:39 < dongs> so its def not priority issue
2015-09-16T04:16:39 < dongs> check that you
2015-09-16T04:16:43 < dongs> 1) enabled usart6 power
2015-09-16T04:16:45 < dongs> 2) set proper af

2015-09-16T04:16:53 < dongs> etc.
2015-09-16T04:16:53 < aandrew> right
2015-09-16T04:17:04 < aandrew> I have to screw with this a bit, it's going to be something idiotic, I can feel it
2015-09-16T04:17:21 < aandrew> yep power's set up, clock is set up, GPIO is set up
2015-09-16T04:20:28 < dongs> maue sure you didnt do something dumb like passing APB2_USART6 to RCC_APB1_Power() or watever thing.
2015-09-16T04:27:05 < aandrew> indeed
2015-09-16T04:27:11 < aandrew> there's a lot of bits that have to be twiddled right
2015-09-16T04:27:23 < aandrew> pretty sure I got it though

2015-09-16T04:29:35 < hjf> why
2015-09-16T04:29:40 < dongs> are  you gonna write one?
2015-09-16T04:29:42 < hjf> i mean the bootloader is open source
2015-09-16T04:29:58 < hjf> bootloader or whatever the platform is called
2015-09-16T04:30:46 < hjf> remember that problem i was having with the stm32 that only wanted to work at certain voltages?
2015-09-16T04:30:55 < hjf> i figured it's temperature related
2015-09-16T04:30:55 < dongs> right
2015-09-16T04:31:05 < dongs> surely not, its a sideffect of somethign else
2015-09-16T04:31:16 < hjf> well i mean
2015-09-16T04:31:33 < hjf> i left some blinker code running (on top of netduino) and the stm32 gets warm
2015-09-16T04:31:42 < hjf> warm enough to feel warm at touch
2015-09-16T04:32:05 < hjf> if i unplug it and plug it back in, it won't boot until a few minutes have passed
2015-09-16T04:32:32 < dongs> < hjf> warm enough to feel warm at touch
2015-09-16T04:32:34 < dongs> you broke it
2015-09-16T04:32:40 < hjf> i mean, it wont boot by itself. i have to leave it unplugged until it cools down
2015-09-16T04:32:43 < dongs> that means you killed some pins w/ESD or so
2015-09-16T04:32:49 < dongs> next will be cratering
2015-09-16T04:33:23 < hjf> could be, i asked the owner of this board to bring me some STM32s and he put them in a... plastic bag
2015-09-16T04:33:26 < hjf> inside his wallet
2015-09-16T04:33:42 < hjf> why the fuck did he even take them off the tape n reel is beyond me
2015-09-16T04:34:34 < hjf> but anyway, i swapped the IC for one of these and i have the exact same problem anyway
2015-09-16T04:34:56 < hjf> so i doubt *that* problem is ESD related. i mean what are the fucking chances?

2015-09-16T04:38:48 < hjf> i expect it to warm up no?
2015-09-16T04:40:23 < hjf> well because 20 years ago we needed a heatsink and a fan on a pentium processor

2015-09-16T06:00:09 < aandrew> hm interesting
2015-09-16T06:00:40 < aandrew> screwing with __HAL_RCC_GPIOC_CLK_ENABLE() is causing weirdness with UART2 which is already enabled
2015-09-16T06:00:57 < aandrew> UART2's pins are on GPIOA too, so there shouldn't be any conflict yet there is
2015-09-16T06:01:32 < emeb_mac> bizarre
2015-09-16T06:01:44 < emeb_mac> I've just started messing with HAL stuff
2015-09-16T06:01:57 < emeb_mac> it's nice that so many of those RCC things are CPP macros
2015-09-16T06:02:31 < emeb_mac> but it's probably worth looking into the .h files to see if there are bugs in the implementation
2015-09-16T06:02:39 < aandrew> I don't doubt there are
2015-09-16T06:02:49 < aandrew> I still don't have it working 100% but this is a definite clue

2015-09-16T07:01:40 < upgrdman> R2COM, you ever use a gate driver for high-side nmos?
2015-09-16T07:02:49 < hjf> so i found someone who has a similar problem to mine: sometimes it will boot, sometimes it won't, on a custom board
2015-09-16T07:02:58 < hjf> but he's using chibiOS
2015-09-16T07:03:16 < hjf> the thing that fixed it for him was removing -Os
2015-09-16T07:03:36 < hjf> it made the program much larger but it worked every time
2015-09-16T07:04:12 < upgrdman> R2COM, so you know how they use a cap and diode to pump, right?
2015-09-16T07:04:53 < upgrdman> R2COM, problem i might have is the source of the high side fet could go below 0V. and i don't want to pump too high, since >20V will fuck my fet.

2015-09-16T07:09:36 < upgrdman> and one side of the diode goes negative for a period of time
2015-09-16T07:09:57 < upgrdman> while the other side of the diode stays at Vout
2015-09-16T07:11:37 < upgrdman> thats how SEPICs work
2015-09-16T07:11:55 < upgrdman> https://upload.wikimedia.org/wikipedia/commons/thumb/c/c8/SEPIC_Schematic.gif/500px-SEPIC_Schematic.gif
2015-09-16T07:12:20 < upgrdman> when S1 closes, the diode anode goes negative
2015-09-16T07:12:55 < upgrdman> and in my circuit, it can go to almost -20V
2015-09-16T07:13:21 < upgrdman> so if the charge cap of my gate drives see's that, the gate drive voltage could end up way too high and pop my poor little gate

2015-09-16T10:08:25 < TheSeven> karlp: the weird interface of GPIO has performance reasons. the way it's built it should avoid any indirect (vtable) calls as long as there's only one GPIO controller present
2015-09-16T10:08:46 < TheSeven> if there's just one GPIO controller, a GPIO::Pin object is just a uint8 pin number
2015-09-16T10:09:04 < TheSeven> if there's multiple, it's a controller number / pin number pair, 8 bits each
2015-09-16T10:09:33 < TheSeven> actually instantiating an object for all of those pins would be a problem...
2015-09-16T10:10:26 < TheSeven> this discussion is making me think about another way how it could possibly be done though... let me know if you have any clever ideas how to trick the compiler into doing what I need ;)

2015-09-16T11:39:29 < dongs> yeah, thats wat im saying, it'll work either way probly
2015-09-16T11:39:32 < Ecco> ok
2015-09-16T11:39:33 < dongs> no, its 22R resistor
2015-09-16T11:39:49 < Ecco> oh ok, I'm not used to SMD markings
2015-09-16T11:39:55 < dongs> it isnt
2015-09-16T11:39:59 < dongs> 22R = 22 ohm
2015-09-16T11:40:07 < Ecco> oh
2015-09-16T11:40:08 < Ecco> ok :-D
2015-09-16T11:40:19 < Ecco> THat seems awfully low
2015-09-16T11:40:39 < Ecco> What does it do?
2015-09-16T11:41:40 < GargantuaSauce> matches the characteristic impedance of the usb bus
2015-09-16T11:42:05 < Ecco> oh, ok
2015-09-16T11:42:13 < Ecco> I had no idea you had to do impedance matching
2015-09-16T11:42:25 < dongs> you dontreally for FS
2015-09-16T11:42:45 < GargantuaSauce> yeah and again i think the f4 might have it internally but not sure
2015-09-16T11:43:02 < GargantuaSauce> so consult the holy scriptures to conduct the rites correctly
2015-09-16T11:43:05 < dongs> their evalboards that have chips that NEED it still dont mount them
2015-09-16T11:43:28 < Ecco> GargantuaSauce: haha :-)
2015-09-16T11:43:37 < Ecco> ok
2015-09-16T11:43:42 < Ecco> I had no idea it was so simple
2015-09-16T11:44:07 < Ecco> And, correct me if I'm wrong, but USB is 5V logic
2015-09-16T11:44:25 < Ecco> Whereas my chip is powered straight from a CR2032, so somewhere between 2 and 3V
2015-09-16T11:44:35 < Ecco> Wouldn't that be problematic?

2015-09-16T11:46:11 < Ecco> oh wrong USB is not 5V?
2015-09-16T11:46:38 < Ecco> Well that's what wikipedia seems to say
2015-09-16T11:46:54 < GargantuaSauce> https://en.wikipedia.org/wiki/USB#Signaling
2015-09-16T11:47:24 < Ecco> Oh indeed
2015-09-16T11:47:44 < Ecco> In the summary of that same page, on the top
2015-09-16T11:47:58 < Ecco> it does say "Electrical : Signal  : 5V DC"
2015-09-16T11:47:59 < dongs> kikepedia is never wrong
2015-09-16T11:48:32 < GargantuaSauce> i'd tell you to go read the usb specs buuut i am not sure i would wish that on another living being
2015-09-16T11:48:43 < Ecco> :-D
2015-09-16T11:49:31 < GargantuaSauce> think i have a decent tutorial somewhere but not at hand so get googling
2015-09-16T11:50:14 < Ecco> will do
2015-09-16T11:50:28 < PaulFertser> http://www.beyondlogic.org/usbnutshell/usb1.shtml ?
2015-09-16T11:55:40 < PaulFertser> What do you guys think of https://ncrmnt.org/wp/2015/09/02/stencils/ ?
2015-09-16T12:04:46 < zyp> no, usb is 3.3V signalling
2015-09-16T12:05:05 < zyp> well, LS/FS is
2015-09-16T12:05:15 < zyp> HS is even lower, some current loop mode
2015-09-16T12:06:05 < dongs> OK
2015-09-16T12:06:08 < dongs> GD32 i2C is definitely fixed
2015-09-16T12:06:21 < dongs> from stm32
2015-09-16T12:07:54 < qyx_> how much is this gd32 cbt6?
2015-09-16T12:08:00 < dongs> less than f103
2015-09-16T12:08:03 < dongs> gonna try software i2c first
2015-09-16T12:08:05 < dongs> since i know that works
2015-09-16T12:08:07 < dongs> to see if other shit is ok
2015-09-16T12:08:36 < Lux> dongs: so something between 1$ and 2$ ?
2015-09-16T12:09:46 < dongs> heh yeah software i2c works
2015-09-16T12:10:20 < dongs> so i just fix that and i can use GD32 as substitutte

2015-09-16T12:49:31 < Ecco> I just googled them up
2015-09-16T12:49:44 < Ecco> holly shit, they're like €500+
2015-09-16T12:50:03 < Ecco> I quite don't see how this beats a $3 st-link
2015-09-16T12:50:21 < PaulFertser> "You can get one for about 150$ on ebay"
2015-09-16T12:50:24 < Ecco> (I'm pretty sure it does, but in practice I wonder what it does better)
2015-09-16T12:50:36 < Roklobsta> PaulFertser: East Germany.
2015-09-16T12:50:39 < Ecco> Well, that's would still be 50x more expensive :-D
2015-09-16T12:51:17 < Ecco> (well ok, the stlink is not $3, but you're very likely to have one lying around since ST seems to be putting one on pretty much all their dev boards
2015-09-16T12:51:18 < PaulFertser> Ecco: ah, talking about j-link, well, they have more features. Support for arbitarary JTAG operations, automatic software breakpoints for flash regions.
2015-09-16T12:51:35 < Laurenceb_> I'm betting SWO is faster?
2015-09-16T12:51:44 < Ecco> how would that translate over once in GDB?
2015-09-16T12:51:59 < Ecco> So far I'm using openocd+stlink and I don't feel like I've hit any restriction
2015-09-16T12:52:11 < Laurenceb_> in b4 dongs
2015-09-16T12:52:13 < PaulFertser> Yes, a bit, IIRC it's ~7.5MHz max with J-Link and 2MHz max with st-link. But you can get 12MHz with FT232H :)
2015-09-16T12:52:57 < PaulFertser> Ecco: you can't place too many breakpoints on flash.
2015-09-16T12:53:15 < Ecco> hmm
2015-09-16T12:53:21 < PaulFertser> Ecco: also, you do not need to work with MIPS or Cortex-A etc. Then stlink wouldn't be adequate.
2015-09-16T12:53:30 < Ecco> Ok, makes sense
2015-09-16T12:53:38 < Ecco> Regarding the number of breakpoints
2015-09-16T12:53:55 < Ecco> I've been developing software for a while now, and I find that having too many breakpoints is actually a pain
2015-09-16T12:53:58 < PaulFertser> Also, with jlink you can mass-erase kinetis, with stlink -- no.
2015-09-16T12:54:04 < Ecco> and a symtom of poorly placed breakpoints
2015-09-16T12:54:28 < PaulFertser> I'm sure dongs can tell you more about why jlink is great.
2015-09-16T12:54:36 < Ecco> ok :)
2015-09-16T12:55:58 < dongs> jlink goes up to 50mhz
2015-09-16T12:56:00 < dongs> swd
2015-09-16T12:56:07 < dongs> lol @ ft232h garbage
2015-09-16T12:56:09 < dongs> fuck right off.
2015-09-16T12:56:56 < PaulFertser> dongs: SWD, and I'm talking about SWO capture.
2015-09-16T12:57:13 < PaulFertser> dongs: ft232h garbage goes up to 30MHz.
2015-09-16T12:57:29 < dongs> PaulFertser: is that with FREE AS IN BEER driver
2015-09-16T12:57:32 < PaulFertser> Show me someone who uses higher than that.
2015-09-16T12:57:38 < dongs> or with FILTHY COMMERCIAL SHIT THAT REQUIRES YOU TO RECOMPILE OPENOCD
2015-09-16T12:58:29 < PaulFertser> dongs: 30MHz is obtainable with either, that's how the HW works.
2015-09-16T12:58:48 < dongs> PaulFertser: somehow i dont think so
2015-09-16T12:59:09 < PaulFertser> dongs: I've seen 30MHz on a scope myself.

2015-09-16T12:59:43 < PaulFertser> Why wouldn't it work? It's just a configuration register, you set whatever prescaler, bah, ftdi chip talks on the choosen frequency.
2015-09-16T13:00:11 < dongs> ftdi has manchester decoding for SWO?
2015-09-16T13:00:30 < PaulFertser> No.
2015-09-16T13:00:35 < PaulFertser> UART only.
2015-09-16T13:00:46 < PaulFertser> Did you ever really need manchester?
2015-09-16T13:03:11 < PaulFertser> You pay 30$ for TUMPA and get almost the same speed as j-link. With faster (TUMPA does 12MHz, j-link 7.5MHz) SWO capture.

2015-09-16T17:26:09 < Laurenceb>  1 slight issue: the nuts fly off - thats why theres tape
2015-09-16T17:29:45 < mtbg> so maybe metal sheet cans over the nuts for next version?
2015-09-16T17:30:12 < Laurenceb> yeah - just SLS nylon from the central shaft adaptor

2015-09-16T17:31:48 < mtbg> you could also use some lead or bismuth fishing weights and cut/mold them is more convenient shape

2015-09-16T17:44:27 < yan_> ugh talk about scope creep.. i didn't like having a single large header file containing all the pin/gpio definitions so i spent three days writing a custom language description for the hardware and a parser for it to generate the pin file automatically and cross-reference all the buses to pins to peripherals to timers

2015-09-16T17:46:19 < yan_> i was porting old code to new hardware i just finished assembling
2015-09-16T17:46:45 < yan_> firmware's 50% done, hardware is on second prototype, and i also spent a few days reworking the build system to make crosscompiling easier (for testing)
2015-09-16T17:46:52 < yan_> i don't usually take detours until i have shit sort of working

2015-09-16T23:20:09 < upgrdman_> "specialized op amps" you mean high-side current amp ic?
2015-09-16T23:20:13 < GargantuaSauce> oh yes use one of those
2015-09-16T23:20:13 < qyx_> yes
2015-09-16T23:20:20 < upgrdman_> like ti ina199 or whatever its called
2015-09-16T23:20:27 < qyx_> yep
2015-09-16T23:20:38 < qyx_> also zetex has some
2015-09-16T23:20:41 < upgrdman_> ya i use some from ti. work great. super easy.
2015-09-16T23:21:09 < upgrdman_> and they can drive an adc pin without needing to increase stm's sampling period
2015-09-16T23:22:25 < kakimir> upgrdman_: low side definitelly
2015-09-16T23:23:09 < kakimir> I don't want to rely on special parts
2015-09-16T23:23:26 < upgrdman_> kakimir, so i came to this conversation late. wtf are you trying to do now?
2015-09-16T23:23:28 < GargantuaSauce> they arent really special
2015-09-16T23:23:52 < kakimir> gatedriver lowside shunt
2015-09-16T23:24:19 < kakimir> posibility to range bidirectional current to 0-3v3 output range
2015-09-16T23:25:05 < upgrdman_> bidir low side?
2015-09-16T23:25:15 < kakimir> yes
2015-09-16T23:25:22 < upgrdman_> so your gate will have a negative voltage at it's drain?
2015-09-16T23:25:35 < upgrdman_> *so your FET
2015-09-16T23:25:36 < kakimir> no

2015-09-17T07:02:04 < yan_> ok this is driving me nuts. every time i flash my binary via openocd and connect via openodb, symbols have different values.. _data is an export in my linker file that should point to the start of data section. readelf on the binary confirms it. yet when i 'p/x _data' after a fresh reset, each time it's something different
2015-09-17T07:02:48 < yan_> *connect via gdb
2015-09-17T07:03:24 < yan_> and it's sometimes 0xe0042300, which i can't google as a magic value.. i sometimes get sp set to that too
2015-09-17T07:06:59 < jpa-> what does    info symbol _data   tell?
2015-09-17T07:07:52 < jpa-> also maybe you are printing the data at the start of the data section (uninitialized ram?) instead of the address of _data

2015-09-17T07:17:29 < upgrdman> and before you comment about the ringing, that isn't causing this particular problem. replacing the gate with a real 10nF cap to sim it, and the waveform has that slow rise time too
2015-09-17T07:19:37 < upgrdman> i tried 2.2nf iirc, and it was cleaner
2015-09-17T07:20:10 < upgrdman> so, ya. 4A driver, plan to PWM at 100kHz+, should be decent

2015-09-17T12:19:04 < Ecco> hmm, ok I've a very very weird bug :(
2015-09-17T12:19:24 < Ecco> float my_function() { ... };
2015-09-17T12:19:39 < Ecco> In this function, I build a float manually, according to the IEEE754 spec
2015-09-17T12:19:56 < Ecco> If I inspect the return value in GDB, it's 0x3f800000 which is 1.0f
2015-09-17T12:20:23 < Ecco> and, strangely, I get a fault on the last line of my_function, on the return statement
2015-09-17T12:21:12 < zyp> which platform?
2015-09-17T12:21:17 < Ecco> STM32F401
2015-09-17T12:21:36 < zyp> have you enabled the FPU?
2015-09-17T12:21:38 < Ecco> so the core is CM4F
2015-09-17T12:21:44 < Ecco> zyp: Not manually
2015-09-17T12:21:49 < Ecco> Well, no
2015-09-17T12:22:06 < Ecco> Am I supposed to do it myself?
2015-09-17T12:22:12 < zyp> right, but you're still compiling with hardfloat-ABI?
2015-09-17T12:22:22 < Ecco> yes

2015-09-17T12:22:40 < Ecco> oh no
2015-09-17T12:22:43 < zyp> hardfloat-ABI says that a function returning float will return it in one of the FPU registers, not the CPU registers
2015-09-17T12:22:52 < Ecco> oh
2015-09-17T12:22:53 < Ecco> ok
2015-09-17T12:23:29 < zyp> well, softfp means you're not
2015-09-17T12:23:33 < Ecco> Actually I wonder why I have to worry about such details myself. Shouldn't the compiler handle that for me anyway?
2015-09-17T12:23:40 < zyp> sure

2015-09-17T12:23:45 < Ecco> yeah I thought I used hardfloat, but in fact I don't
2015-09-17T12:23:53 < zyp> but if it requires usage of the FPU, it need to be enabled
2015-09-17T12:24:04 < zyp> which you have to do manually during startup code
2015-09-17T12:24:20 < Ecco> oh, ok
2015-09-17T12:24:23 < Ecco> Gotcha
2015-09-17T12:24:41 < Ecco> So a way to test that this is indeed the issue
2015-09-17T12:24:49 < Ecco> could be to just write some generic code that uses floats
2015-09-17T12:24:52 < Ecco> and see what it does
2015-09-17T12:24:55 < zyp> yes
2015-09-17T12:24:59 < Ecco> ok, excellent
2015-09-17T12:25:02 < Ecco> let me try that
2015-09-17T12:25:06 < Ecco> and thanks a lot already!

2015-09-17T12:27:53 < zyp> http://infocenter.arm.com/help/topic/com.arm.doc.dui0553a/BABDBFBJ.html <- read up here on how to enable it
2015-09-17T12:36:27 < Ecco> Why isn't it enabled by default? It eats up power?
2015-09-17T12:36:38 < Ecco> Should I disable it to save battery when i don't use it?
2015-09-17T12:38:14 < jpa-> IIRC the difference in power usage is pretty small
2015-09-17T12:38:23 < Ecco> so why bother?
2015-09-17T12:39:11 < jpa-> good question
2015-09-17T12:39:14 < Ecco> :-)
2015-09-17T12:39:42 < Ecco> So i've written my own "crt0" code
2015-09-17T12:39:44 < jpa-> if you enable FPU saving in interrupts, that takes significantly more stack RAM
2015-09-17T12:39:47 < Ecco> would that be a good time to enable FPU?
2015-09-17T12:40:12 < jpa-> i would enable it in the same place where clock is initialized, flash wait states is set etc.
2015-09-17T12:40:20 < Ecco> uuuhhhh
2015-09-17T12:40:27 < Ecco> I'm not doing any of this
2015-09-17T12:40:31 < Ecco> :-D
2015-09-17T12:40:36 < jpa-> so you are running in just 8MHz?
2015-09-17T12:40:39 < Ecco> yes
2015-09-17T12:40:51 < Ecco> Or 16 maybe? I don't remember the default clock
2015-09-17T12:40:56 < jpa-> ok, well i think at some point you'll want to run faster :)
2015-09-17T12:41:09 < jpa-> usually the code where you initialize that is called "system init" or similar
2015-09-17T12:41:12 < Ecco> or slower :-D
2015-09-17T12:41:15 < Ecco> ok

2015-09-17T14:53:24 < qyx_> for potting dc-dc converters in aluminum cases
2015-09-17T14:54:49 < dongs> i used epoxy shit

2015-09-17T15:39:56 < jubatus> did you use a potting compound specifically made for electronics ?
2015-09-17T15:40:24 < jubatus> e.g. if you use normal silicone on a PCB the acetic acid will kill the chips.

2015-09-17T15:41:40 < qyx_> this one seems good

2015-09-17T16:07:58 < Sync> but yeah I designed gen2 hardware
2015-09-17T16:10:24 < dongs> cool
2015-09-17T16:11:05 < Sync> we can drive rexroth 600V servos rock solid

2015-09-17T17:09:49 < ReadError> A Doctor of Philosophy degree (often abbreviated Ph.D., PhD, D.Phil., or DPhil[1]) or a Doctorate of Philosophy, from the Latin Doctor Philosophiae, is a type of doctorate awarded by universities in many countries.
2015-09-17T17:09:49 < ReadError> The degree varies considerably according to the country, institution, and time period, from entry-level research degrees to higher doctorates. A person who attains a doctorate of philosophy is automatically awarded the academic title of doctor. During the studies that lead to the degree, the student is called doctoral student, Ph.D. student, or D.Phil. student.
2015-09-17T17:11:11 < ReadError> Philosophy is the study of the general and fundamental nature of reality, existence, knowledge, values, reason, mind, and language.

2015-09-17T17:16:31 < PaulFertser> When you're calculating led resistors with Ohm's law, can it be called applied mathematics? No way, you're just using the tool the mathematicians gave you without understanding it at all. You're just applying (trivial in your view) subset of what the real scientists provided you with. And if all you do is using a "magic wand" how is that can be called a part of a science when in fact that wand is

2015-09-17T17:37:38 < Ecco> My naive way is columns = outputs, and row = inputs pulled down
2015-09-17T17:38:06 < Ecco> IIRC, the issue was that two columns could end up being short-circuited if pressed together
2015-09-17T17:38:22 < Ecco> so having outputs trying to drive both low *and* high at the same time

2015-09-17T17:59:50 < Ecco> input has pull-up
2015-09-17T17:59:56 < Ecco> but it's a pull-up, not a "drive" up
2015-09-17T18:00:09 < Ecco> i.e. if open drain drives low, very little current will actually flow
2015-09-17T18:00:10 < Ecco> right?
2015-09-17T18:01:13 < BrainDamage> if open drain drives low, you have a direct crossbar current from the pullup to gnd trough the output transistor
2015-09-17T18:01:20 < BrainDamage> the amount of current depends on the transistor
2015-09-17T18:01:43 < BrainDamage> err, te resistor
2015-09-17T18:01:56 < BrainDamage> plus some extra to charge parasitic capacity
2015-09-17T18:02:23 < Ecco> but that would be small because there's a resistor in the circuit
2015-09-17T18:02:25 < BrainDamage> when the transistor opens, the static current will be from leak, and the dominant current instead is an ephemeral one to charge the cap
2015-09-17T18:02:30 < Ecco> (likely to be in the thousands of ohms)
2015-09-17T18:02:37 < BrainDamage> depends on the resistor, but yes
2015-09-17T18:02:50 < Ecco> ok :)
2015-09-17T18:02:56 < Ecco> Great

2015-09-17T18:03:39 < PaulFertser> Getty: I tried watching those series but couldn't manage for more than 5 minutes, the background laughter was intolerable for me.
2015-09-17T18:04:11 < BrainDamage> ideally the resistor will be a tradeoff between noise tollerance, static power consumption and switch speed, in pratice everyone slaps a value around 10k
2015-09-17T18:04:15 < dongs> typical american garbage
2015-09-17T18:04:19 < Getty> PaulFertser: the jokes are really good, like it

2015-09-17T20:51:54 < Ecco> ok. Why?
2015-09-17T20:52:27 < mtbg> because the pullups have to reload the small capacitance of pcb traces and input pins

2015-09-17T20:53:32 < mtbg> it should reload in some hundreds nanoseconds
2015-09-17T20:53:35 < Ecco> (I mean, something that would wait and not eat a lot of power)
2015-09-17T20:54:19 < mtbg> which can require some dozen clock cycles depending on the frequency
2015-09-17T20:54:32 < Ecco> mtbg: ok:)

2015-09-17T23:20:25 < yan_> qyx_: hm thanks. my stm32 is hanging on recv(), trying to rule out issues.. RCC clocks are enabled, gpio is enabled+configured
2015-09-17T23:21:22 < zyp> yan_, you say clocks are enabled, but are they correctly configured?
2015-09-17T23:21:46 < zyp> IIRC L1 has source selectors for those clocks in RCC
2015-09-17T23:22:09 < zyp> you might be running off a clock that's way slower than you thing and thus get a completely wrong baudrate
2015-09-17T23:22:43 < zyp> I suggest testing TX first, check that the output signal looks sane on a logic analyzer
2015-09-17T23:23:13 < yan_> zyp: i'm doing 'rcc_periph_clock_enable(RCC_USART1); rcc_peripheral_enable_clock(&RCC_APB2ENR, RCC_APB2ENR_USART1EN);'
2015-09-17T23:23:27 < yan_> zyp: that's via libopencm3.. i don't have access to my scope right now, trying to rule out any software issues first
2015-09-17T23:23:46 < zyp> read the RCC chapter in the RM on clock sources
2015-09-17T23:24:33 < yan_> zyp: looking at it now.. in the meantime, do i need to do anything special to run it in asynchronous mode?
2015-09-17T23:24:51 < zyp> no, it's async by default
2015-09-17T23:25:40 < zyp> hmm, actually, disregard what I said about clock sources, L1 doesn't have those
2015-09-17T23:26:39 < yan_> zyp: yeah, none of the example code i've seen used them
2015-09-17T23:28:32 < yan_> zyp: the way i configure: https://gist.github.com/anonymous/10d7ab3180f4e8c8c9f3

2015-09-18T07:26:50 < upgrdman> BuildSmart, uh what? fpga's and mcu's fill different purposes
2015-09-18T07:27:53 < BuildSmart> examples are LPC1768, this is an FPGA if I'm not mistaken.
2015-09-18T07:29:20 < ds2> hmmm?

2015-09-18T07:43:33 < BuildSmart> due to the limited IO's in the AVR I've we've decided to move to STM32 where we have 113 useable IO lines.

2015-09-18T07:47:53 < BuildSmart> for a 5-axis machine, just to drive motion homes and limits requires 35 IO, add spindle control, a tool changer, live tooling and you need about 90 IO
2015-09-18T07:49:32 < BuildSmart> since you can't buy a development board that can be used as a backbone because it provides stuff you don't need that waste IO lines we have decided we will produce all boards as required.
2015-09-18T07:50:59 < dongs> yeah i duno, plus i dont think you really need all that I/O for ALL of them
2015-09-18T07:51:02 < BuildSmart> I've thought about the EPM240, have done a little work with one but I'm not comfortable with it.

2015-09-18T07:56:50 < BuildSmart> memory is managed by hardware
2015-09-18T07:57:15 < dongs> what "hardware" would that be?
2015-09-18T07:58:38 < dongs> http://forum.flyzano.com/viewtopic.php?p=11739#p11739
2015-09-18T07:59:06 < BuildSmart> TI produces a DDR3 memory controller, they have some reference designs and application notes.
2015-09-18T08:01:47 < dongs> link
2015-09-18T08:02:28 < BuildSmart> initially we thought that we could make the entire controller with minimal parts however, this has proven to be impossible due to the requirements, moving tp a 176pin STM32F4 helped regain some lost IO but as we fix problems we lose IO and are now again running low.
2015-09-18T08:02:32 < BuildSmart> link for what?
2015-09-18T08:02:59 < dongs> the "TI DDR3 memory controller"
2015-09-18T08:03:04 < dongs> and what is its output?
2015-09-18T08:03:09 < BuildSmart> sec
2015-09-18T08:04:21 < BuildSmart> http://www.ti.com/lit/ug/sprugv8e/sprugv8e.pdf
2015-09-18T08:05:37 < BuildSmart> without a full BIOS it's impossible to detect memory size and speed so it's hard-coded for a single 256MB dimm
2015-09-18T08:08:33 < dongs> uh
2015-09-18T08:08:42 < dongs> this is describing some DDR3 controller in omap or someshit
2015-09-18T08:09:26 < dongs> KeyStone II aka TMS320C66whatever
2015-09-18T08:10:26 < dongs> what does this have todo with STM32
2015-09-18T08:10:48 < PaulFertser> Also, one hardly needs any "BIOS" to read SPD data from a memory stick: https://en.wikipedia.org/wiki/Serial_presence_detect#DDR3_SDRAM
2015-09-18T08:11:12 < dongs> 256mb? they dont evne make DDR3 in 256mb
2015-09-18T08:11:40 < BuildSmart> sorry DDR2 SO-DIMM
2015-09-18T08:12:14 < BuildSmart> no it is a DDR3 SO-DIMM 256MB
2015-09-18T08:12:30 < BuildSmart> I just read the labbel on it.
2015-09-18T08:14:09 < dongs> you're full of shit
2015-09-18T08:14:15 < PaulFertser> BuildSmart: so, what IC is it actually connected to?
2015-09-18T08:14:56 < upgrdman> so annoying that amazon can sell a 7" tablet for $50 but you cant even but the lcd for that price.
2015-09-18T08:15:12 < dongs> STM32F429 has SDRAM controller, i suppose there's some slight chance you can interface it with an ancient SDRAM so-dimm
2015-09-18T08:15:18 < dongs> but not DDR1/2/3
2015-09-18T08:17:25 < BuildSmart> it says DDR3-800 256MB X 8, we show the full 256MB as writable memory.
2015-09-18T08:19:40 < BuildSmart> we've already off-loaded video onto a second STM32 to gain some IO back but everything is getting complicated and large and we're looking for a way to simplify things as making all these custom boards for velopment work is becoming counter-productive.

2015-09-18T08:21:23 < BuildSmart> I bought a 7.0in TFT for a Mega2560, it chewed up 42 IO lines

2015-09-18T08:26:37 < BuildSmart> the SAM is providing ethernet and other non-required hardware and the number of available IO lines is in question.
2015-09-18T08:28:48 < BuildSmart> a TI memory controller.
2015-09-18T08:34:26 < PaulFertser> BuildSmart: but the link you gave is describing a module in some SoC, not a dedicated controller IC.
2015-09-18T08:36:04 < BuildSmart> if you read it it describes a collection of IC's to manage the memory
2015-09-18T08:36:24 < BuildSmart> TI provides applicaiton notes and engineering bulletins.
2015-09-18T08:37:26 < PaulFertser> BuildSmart: so, what specific IC are you using and how do you interface that IC to stm32f4?

2015-09-18T08:54:12 < BuildSmart> PaulFertser: TMS320DM696TL is the external memory interface IC
2015-09-18T08:54:21 < dongs> uh
2015-09-18T08:54:31 < dongs> thats a DSP that can probably run all your CNC crap by itself
2015-09-18T08:54:35 < dongs> why is STM32 even involved
2015-09-18T08:55:52 < BuildSmart> a DSP, the application note calls it an External Memory Controller so we got some samples.
2015-09-18T08:56:49 < dongs> yaman
2015-09-18T08:57:03 < dongs> I've got this bridge i can sell you

2015-09-18T08:57:43 < dongs> if this isnt CNC equivalent of ZANO i duno wat it is
2015-09-18T08:58:51 < BuildSmart> what do I need the bridge for??
2015-09-18T08:59:09 < BuildSmart> the circuit has gotten complicated enough all on it's own.
2015-09-18T08:59:32 < BuildSmart> I'm trying to simpllfy it
2015-09-18T09:00:53 < qyx_> why do you need DDR3 memory on a CNC controller?
2015-09-18T09:01:05 < qyx_> keep it simple, remove it
2015-09-18T09:01:24 < dongs> qyx, he doesn't have enough I/O
2015-09-18T09:01:50 < BuildSmart> dongs, we need memory and IO
2015-09-18T09:01:56 < dongs> for what
2015-09-18T09:02:00 < qyx_> memory for hat
2015-09-18T09:02:42 < BuildSmart> to load in a NC file, to utilize a look-ahead buffer, to allow funcitons in the NC code so it all has to be resident.
2015-09-18T09:03:09 < dongs> fseek() works pretty good
2015-09-18T09:03:22 < dongs> i heard its a cool function
2015-09-18T09:04:59 < BuildSmart> maybe for a simple single subroutine in an NC file you can get away with seek
2015-09-18T09:05:22 < dongs> what programming genius is writting your shit, since its not "grbl garbage"
2015-09-18T09:05:43 < dongs> that he needs entire file cached in ram
2015-09-18T09:06:31 < BuildSmart> the code is from a known manufacturer and it's RS274 compliant
2015-09-18T09:06:58 < sadara> motion control can get pretty complex, software wise...
2015-09-18T09:07:33 < sadara> what type of motion?
2015-09-18T09:07:59 < BuildSmart> it's 3-dimensional spatial interpolating 5-axis simultaneously
2015-09-18T09:08:52 < sadara> is it snap crackle or pop?
2015-09-18T09:09:37 < BuildSmart> GRBL is got so much missing it wasn't worth considering, the planner code has so many errors and flaws and with such crucial gcode missing it's pretty much useless in a real environment.
2015-09-18T09:10:28 < BuildSmart> at least ECM2 is using RS274ngc code which is ppretty much compliant.
2015-09-18T09:11:38 < sadara> EMC is pretty advanced, I think it is a snap derivative
2015-09-18T09:12:00 < sadara> One  of the reasone the path planner needs so much RAM
2015-09-18T09:12:49 < sadara> *reasone = reasons
2015-09-18T09:14:10 < BuildSmart> the RS274ngc code is the open source version of the FANUC RS274 code

2015-09-18T09:43:19 < BuildSmart> I didn't say it was easy or simple
2015-09-18T09:43:57 < BuildSmart> the board has gotten extremely complicated and large, we're looking to find a simpler solution.
2015-09-18T09:44:17 < sadara> that is not a memory interface
2015-09-18T09:45:15 < sadara> that is the same as calling a STM32F7 a GPIO expander
2015-09-18T09:45:52 < BuildSmart> funny cause on the main page it says it's a memory interface.

2015-09-18T09:56:55 < sadara> on RAM, but it is I2C
2015-09-18T09:57:49 < sadara> yeah, it's called SPD
2015-09-18T10:01:39 < BuildSmart> all I can say is that it's gotten extremely complicated and large, the guy making the decisions on required hardware has made decisions based on percieved needs, from what should have been a small simple board has turned into an extremely large and complicated board and I was hoping to find someone who is more equiped to make the right decisions join us as anything more than Z80/6502/68000 is beyond my abilities.

2015-09-18T10:52:15 < sadara> do your pathing in a m4 if you want a gui, and a seperate system for the gui
2015-09-18T10:52:23 < Sync> we have a time-optimal path planner running on an f7

2015-09-18T10:54:19 < sadara> the pathing wont be the hard part, as long as the machine is insane acceleration
2015-09-18T10:55:21 < BuildSmart> machine hardware is my area of expertise
2015-09-18T10:55:42 < sadara> BuildSmart, specifically?
2015-09-18T10:56:04 < BuildSmart> I've designed, built and sold miniature ATC spindles and small frames with insane rigidity.

2015-09-18T10:59:02 < Sync> the motion controllers are not really an issue
2015-09-18T10:59:20 < sadara> Sync, I know you don't need an FPGA, it does kill a few birds cheply though. (field IOs, encoder inputs, servo pids etc)
2015-09-18T10:59:59 < BuildSmart> see the pull-down   http://www.dalecnc.com/

2015-09-18T11:00:52 < Sync> all position control is done in the motion controller itself
2015-09-18T11:00:59 < Sync> everything else is just eh
2015-09-18T11:01:13 < Sync> closing the loop outside the motion controller is not the right way to do it imho
2015-09-18T11:01:17 < PaulFertser> BuildSmart: if you really mean TMS320DM6467 , do you understand that it's an ARM9 core plus a DSP core? And you can do everything you need on it. If someone who designed a board with that part says you should have an stm32 as well to run your application and use that TI SoC as a DDR interface IC, it's just plain BS.
2015-09-18T11:01:44 < sadara> Sync, on a full size CNC maching centre, the "everything else" takes more resources than the motion control
2015-09-18T11:02:40 < sadara> Sync, Your suggesting realtime / JIT path planning in the main loop?

2015-09-18T11:03:28 < BuildSmart> THAT BOLD TEXT!!!!
2015-09-18T11:03:28 < Sync> no, but the path planner just bangs in position commands into the servo drives
2015-09-18T11:03:39 < Sync> and they care about everything else acheiving the position
2015-09-18T11:04:26 < sadara> Sync, that does have several problems if one servo lags
2015-09-18T11:04:39 < BuildSmart> "What bold text?" and "WHAT BOLD TEXT?????" are bold

2015-09-18T11:06:58 < sadara> most ethercat machines can't rigid tap
2015-09-18T11:07:03 < BuildSmart> if you servo lags during rigid taping it either errors out or breaks the tap.
2015-09-18T11:07:19 < sadara> (or the part)
2015-09-18T11:07:22 < BuildSmart> can't rigd tap?
2015-09-18T11:07:59 < Sync> I don't see any reason why they could not rigid tap, and in fact they can do it
2015-09-18T11:08:00 < BuildSmart> what VMC can't rigid tap?
2015-09-18T11:08:10 < sadara> I am probably wrong, but I believe ethercat machines are "loosly coupled"
2015-09-18T11:08:19 < sadara> ethercat, not VMC
2015-09-18T11:08:33 < Sync> most VMCs are now using ethercat or something similar
2015-09-18T11:08:34 < sadara> ethercat is a type of servodrive interconnect
2015-09-18T11:08:49 < Sync> it is designed for stuff like that
2015-09-18T11:09:21 < sadara> if an ethercat machine can rigid tap, it is getting feedback from the drives
2015-09-18T11:09:40 < Sync> it does not need to
2015-09-18T11:10:15 < sadara> you can't path plan drag
2015-09-18T11:10:45 < Sync> you can't, but the drive can follow your position just fine
2015-09-18T11:11:18 < BuildSmart> also the spindle (or spindle motor) requires an encoder to do rigid taping
2015-09-18T11:12:05 < BuildSmart> an encoder is required to orient the spindle for ATC
2015-09-18T11:12:13 < sadara> ok, look at it this way. Your saying that information flow from motion planner to drive is one way, am I understanding you correctly?
2015-09-18T11:12:44 < Sync> yes, which works perfectly well
2015-09-18T11:13:20 < sadara> BuildSmart, he is saying all axis (inc spindle) have encoders, just that the encoder is only connected to the drive, not as a feedback path for the motion controller
2015-09-18T11:13:31 < BuildSmart> no
2015-09-18T11:13:36 < sadara> Sync, your wrong.
2015-09-18T11:13:54 < Sync> then why does my machine do exactly that and works? :)
2015-09-18T11:13:59 < sadara> in theory, reality is a wonderful place.
2015-09-18T11:14:06 < BuildSmart> I have several real CNC panels, encoders are connected to the panel as well as the drive.
2015-09-18T11:14:14 < sadara> Sync, because you built it like that
2015-09-18T11:14:18 < Sync> and so does the datron
2015-09-18T11:14:28 < sadara> specsheet?
2015-09-18T11:14:39 < Sync> there is nothing to see from the specsheet
2015-09-18T11:14:47 < BuildSmart> thre is no way you can rigid tap without at least an encoder on the spindle connected to the panel.
2015-09-18T11:15:15 < Sync> I never said anything about encoders on the spindle
2015-09-18T11:15:28 < BuildSmart> I did
2015-09-18T11:15:28 < Sync> it's just that you don't need to feedback position in the path planner
2015-09-18T11:15:48 < sadara> there is no way you can do "closly coupled"  motion, (read that as fast AND accurate), without feedback
2015-09-18T11:15:49 < BuildSmart> only for Z-axis during rigid taping
2015-09-18T11:16:17 < sadara> so, you either cripple your machine by slowing it down, or by reducing the accuracy
2015-09-18T11:16:28 < Sync> there is feedback, it just is in the servo amp
2015-09-18T11:16:36 < Sync> I'm using glass scales as well
2015-09-18T11:16:38 < sadara> that is not feedback
2015-09-18T11:16:44 < Sync> but they don't have anything to do with the servo amp
2015-09-18T11:16:45 < Sync> eh
2015-09-18T11:16:47 < Sync> path planner
2015-09-18T11:17:12 < Sync> if I'm within my accel and speed limits of the machine, my amp will follow
2015-09-18T11:17:14 < sadara> Sync, so you have crippled your machines speed potential for accuracy
2015-09-18T11:17:20 < Sync> I have not
2015-09-18T11:17:23 < BuildSmart> so your Z is aware of the position of the spindle at all times and you have no spindle encoder feedback to your panel?
2015-09-18T11:18:28 < BuildSmart> that would be a major feat to accomplish without some special tooling
2015-09-18T11:18:53 < Sync> currently I'm using the spindle encoder to feedback into the pathplanner but theoretically (and practically I've tested that) I can just command the spindle to go to an angle and it will do that
2015-09-18T11:19:00 < Sync> and the rest just goes from there
2015-09-18T11:19:20 < Sync> and for the other moves feedback into the path planner is simply not needed
2015-09-18T11:19:39 < sadara> He is saying he would just put a 500hp spindle on, and let the servo drive tell it what to do. and as long as he has a really large saftey margin (like 1000%) and moves the spindle slowly enough the rest of the slow moving 500hp spindles will orient themselves correctly around the spindle, reguardless of if they have to punch through the solid block of cast iron he is machining
2015-09-18T11:20:17 < BuildSmart> for A and C there is also encoder feedback
2015-09-18T11:20:24 < sadara> and only take really light cuts
2015-09-18T11:20:27 < BuildSmart> for X and Y there  isn't
2015-09-18T11:21:05 < sadara> BuildSmart, the only reason that X and Y wouldn't have feedback is economics
2015-09-18T11:21:07 < BuildSmart> there are ports for encoders but neither the Okuma or DooSan have encoders connected on X or Y

2015-09-18T11:23:08 < sadara> with the cost of a couple of timers or gates on a FPGA being close to zero, there is no reason modern CNC equiptment shouldn't be tightly coupled
2015-09-18T11:23:39 < sadara> ie, if an axis slow down, all other axis slow down the exact same amount
2015-09-18T11:24:33 < mervaka> just keep everything in lock-step?
2015-09-18T11:24:37 < sadara> Why would an axis slow down? Maybe it is carrying a heavy part or tool, maybe lack of maintainance/oil/grease, maybe it is overcutting/blunt tool
2015-09-18T11:25:20 -!- Niedar [~nnscript@c-73-133-253-215.hsd1.md.comcast.net] has joined ##stm32
2015-09-18T11:25:43 < sadara> mervaka, you don't do rapids in lock step, but when cutting, it isn't important what speed 1 axis moves, as long as all axis mave at the correct rate
2015-09-18T11:26:05 < BuildSmart> if I pause a running NC, use the MPG to tilt the table, Z auto-position relocates
2015-09-18T11:26:42 < sadara> as I said above, there are many reasons the ACCELERATION/JERK/JOUNCE of an axis may change
2015-09-18T11:27:25 < mervaka> i'll admit motor control isn't something we deal with here much, but that's how i'd approach the problem.
2015-09-18T11:27:59 < sadara> It really comes done to "Why wouldn't you"
2015-09-18T11:28:21 < mervaka> take small steps, and make sure everyone's where they need to be before taking the next steps
2015-09-18T11:28:46 < mervaka> this is of course assuming stepper motors
2015-09-18T11:29:37 < mervaka> but all our motor control systems are just PIDs, and one axis at that.
2015-09-18T11:30:03 < mervaka> so that experience is pretty irrelevant
2015-09-18T11:30:22 < sadara> mervaka, most controllers take it much further than that, they predict the path of each axis, and then calculate correction for all axis in the future, usually in a quaternion matrix, and then decimated into machine "plank" lengths
2015-09-18T11:30:50 < mervaka> it seems motor control theory goes far beyond what i know :)
2015-09-18T11:31:11 < sadara> moving 1 axis is easy
2015-09-18T11:31:22 < sadara> moving two is hard
2015-09-18T11:31:34 < mervaka> i can imagine
2015-09-18T11:32:04 < sadara> but the cost of hardware now makes it possible
2015-09-18T11:32:43 < mervaka> i'll just go back under my rock and continue playing with TFT screens :)
2015-09-18T11:33:01 < sadara> a CNC controller that cost $200000  20 years ago is less powerfull than some of the better opensource controllers used for 3d printers
2015-09-18T11:34:24 < sadara> BuildSmart, google MESANET for an idea about how modern Realtime control is done.
2015-09-18T11:35:11 < sadara> You have a non realtime GUI, a non realtime path planner, and then a real time controller that keeps track of everything

2015-09-18T13:48:07 < Fleck> this is better Laurenceb ;D
2015-09-18T13:52:36 < Bundestrojaner> I try to read Data on a model vehicle with a photo transistor when driving over a IR LED.
2015-09-18T13:52:36 < Bundestrojaner> I use the USART to send and read and i send a 5 Byte-Frame at 19200baud: 0Byte as preamble, 3 Byte Data, a checksum (XOR of the 3 Bytes).
2015-09-18T13:52:36 < Bundestrojaner> Receiving is done with a state-machine and a timeout: the statemachine is resetted if the usart doesn't receive a byte for >3ms.
2015-09-18T13:54:57 < Bundestrojaner> my problem is, that the vehicle starts to receive when it comes into the range of the IR-LED. So i need a possibility to synch...
2015-09-18T13:54:57 < Bundestrojaner> What's the easiest way to do that? My idea is a break of 1,5Byte (=625µs)
2015-09-18T13:55:38 < jpa-> yeah, that is a typical way and works pretty way
2015-09-18T13:55:50 < jpa-> have a 2 bytes worth of pause between the frames
2015-09-18T13:55:53 < jpa-> *pretty well
2015-09-18T13:56:38 < Bundestrojaner> jpa-: i'll try that, thanks :)

2015-09-18T13:57:27 < jpa-> actually 2 bytes pause is not enough for your 3ms timeout - but yeah, adjust as needed
2015-09-18T13:57:43 < jpa-> you could lower the timeout to 0.5ms IMO

2015-09-18T13:59:03 < Bundestrojaner> jpa-: i created the timeout for the case when the vehicle leaves the range of the IR-LED
2015-09-18T14:00:46 < Bundestrojaner> jpa-: i think the usart has a "timeout" itself, because during the break it finishes its last byte and will wait for a startbit

2015-09-18T14:02:12 < Bundestrojaner> btw: do i need an extra break after the 2 stopbits between 2 bytes? because i implemented the usart in software, so i can feed several IR-LEDs with a single ATMega8

2015-09-18T18:41:53 < Ecco> Guys, I really cannot figure out why this effing matrix keyboard doesn't work :(
2015-09-18T18:42:09 < Ecco> SO, I've this row that output key presses from that other row
2015-09-18T18:42:19 < Ecco> all the other rows/columns work just fine
2015-09-18T18:42:46 < Ecco> so naturally, I thought that the defective row was shorted to the row whose keys it outputs
2015-09-18T18:42:50 < Ecco> -> there is no short
2015-09-18T18:42:59 < Ecco> Now, my outputs are OD
2015-09-18T18:43:21 < Ecco> And when I measure an OD output with my multimeter, it keeps beeping
2015-09-18T18:43:29 < Ecco> when the output is floating
2015-09-18T18:43:43 < Ecco> and it shows something near 0V when the OD is pulled low
2015-09-18T18:43:57 < Ecco> so I think I can tell when a row is pulled down or floating
2015-09-18T18:44:32 < Ecco> thing is, the "defective" row is indeed also pulled down when the row whose keys it outputs is pulled down
2015-09-18T18:44:47 < Ecco> so that would look like a short, but when I unplug and test with an ohmmeter, there is no short
2015-09-18T18:45:33 < Ecco> I triple-checked the GPIO_ODR register, and yes, I'm only driving a single row low

2015-09-18T19:12:11 < Ecco> What's stupid is that I actually didn't need the ground plane to be that close to the tracks

2015-09-18T19:19:32 < Ecco> I don't know how big of a fuckup that is
2015-09-18T19:19:39 < Ecco> but they did ground a track
2015-09-18T19:19:51 < Ecco> by bridging it to ground plane nearby
2015-09-18T19:20:14 < Ecco> (and wasted an afternoon for me, because I really thought I was doing things wrong in software)
2015-09-18T19:21:50 < Ecco> Note that out of the 3 PCBs I ordered

2015-09-18T19:28:06 < Ecco> (/me comes from the SE world)
2015-09-18T19:28:24 < Ecco> Question: how do I tell Altium to space out my polygon fill?
2015-09-18T19:28:25 < Getty> i mean, think about, you cant really get forward if you cant save a state
2015-09-18T19:28:34 < Getty> on software development
2015-09-18T19:28:41 < Getty> you cant like "preplan" the thing in detail in your head
2015-09-18T19:28:48 < Ecco> Does it infer the spacing from the design rules?
2015-09-18T19:28:49 < Getty> and then just woop it out when needed
2015-09-18T19:29:48 < Ecco> Oh NVM, found it
2015-09-18T19:29:52 < Ecco> (it's in the polygon manager)
2015-09-18T19:30:30 < BrainDamage> Ecco: e-test is board layout testing, they connect probes to the pcb and check that the implementation matches the design
2015-09-18T19:30:43 < Ecco> Can they do that only with Gerber files?
2015-09-18T19:30:56 < Ecco> Wouldn't then need the schematics info?
2015-09-18T19:30:56 < BrainDamage> sure, why not?
2015-09-18T19:31:10 < Ecco> Well, I guess you can rebuild it from the Gerber
2015-09-18T19:31:18 < Ecco> (my understanding is that gerbers == vector image)
2015-09-18T19:31:48 < Ecco> Another question : why does Altium do this : http://i.imgur.com/s93MTf1.png ? I mean, why bother with the "1 GND" pad? Why not fuse it completly in the polygon fill?

2015-09-18T19:48:00 < aandrew> Ecco: you can tell it not to make thermals with the polygon properties, but you want them
2015-09-18T19:48:46 < aandrew> the problem with large copper pours is that they're a bitch to reflow properly. That owuld be a prime target for that component to "tombstone" (stand up on its end) if the GND were not connected to the plane with a thermal
2015-09-18T19:49:08 < aandrew> the thermal gives a good solid ground connection but helps limit the polygon's ability to suck the heat out of the pad

2015-09-19T01:30:30 < Bundestrojaner> good evening
2015-09-19T01:31:49 < Bundestrojaner> Are there any tricks to get a phototransistor (Vishay TEMT1020) fast (~40KHz rect) (sry for OT)
2015-09-19T01:33:28 < Bundestrojaner> it can't pull a low pullup-R down and with a high pullup, it gets slow

2015-09-19T01:36:11 < zyp> other than that, I can't imagine anything but reducing the impedance on whatever signal you're driving

2015-09-19T01:44:01 < Bundestrojaner> zyp: the only "load" is atm my dso but later an input-pin of stm32
2015-09-19T01:45:16 < upgrdman> ya... you need a stronger phototransistor, or a super-low-input-cap buffer right after it.
2015-09-19T01:46:11 < Bundestrojaner> does it make sens to take 2 phototransistors parallel?
2015-09-19T01:47:36 < zyp> what's your application anyway? what's the light source?
2015-09-19T01:48:58 < Bundestrojaner> zyp: the light source is an IR-LED.
2015-09-19T01:48:58 < Bundestrojaner> my application is a "milestone" for model vehicles
2015-09-19T01:49:31 < zyp> as far as I can tell from the datasheet, 40kHz should be within what's possible for that phototransistor, provided it gets enough light
2015-09-19T01:49:56 < zyp> which pullup values have you tested with?
2015-09-19T01:50:41 < Bundestrojaner> 220, 680, 1K, 2K2
2015-09-19T01:51:23 < Bundestrojaner> 680 works if the transistor is exactly over the led
2015-09-19T01:51:53 < zyp> oh, and which voltage are you pulling to?
2015-09-19T01:52:15 < Bundestrojaner> it can't pull down 220 (even over the led) and >=1K is too slow
2015-09-19T01:52:21 < Bundestrojaner> the pullup is on 5V
2015-09-19T01:52:34 < zyp> yeah, that sounds fair
2015-09-19T01:52:41 < Bundestrojaner> i guess i need <=1,6V for the STM to read low?
2015-09-19T01:53:12 < kakimir> can you do trace impendance matching by trace width transition?
2015-09-19T01:54:00 < zyp> Bundestrojaner, idk, you can/should use some sort of comparator if you need accurate control of that
2015-09-19T01:54:45 < Bundestrojaner> kakimir: what do you mean with impendance matching?
2015-09-19T01:54:58 < Bundestrojaner> what would happen if i use 2 of them in parallel?
2015-09-19T01:55:01 < zyp> but it sounds like it's simply not getting enough light
2015-09-19T01:55:50 < zyp> two in parallel might help
2015-09-19T01:56:09 < Bundestrojaner> zyp: i think the problem is the small distance between diode and transistor
2015-09-19T01:56:15 < kakimir> if I need 2point something millimeter trace to get 50ohm trace in 1point something millimeter board and I don't want to trace that 2point something trace around the board
2015-09-19T01:56:53 < kakimir> but thin it down
2015-09-19T01:56:59 < zyp> kakimir, use a four layer board
2015-09-19T01:57:02 < kakimir> is it okay with transition
2015-09-19T01:57:11 < kakimir> money zyp money
2015-09-19T01:57:25 < zyp> a typical four layer stackup will give you a ground plane under a thin prepreg, which will decrease the trace width for a given impedance
2015-09-19T01:58:31 < kakimir> I'm just trying the get the best out of this 2layer
2015-09-19T01:59:07 < kakimir> if there is application where impendance is priority then it's 4layer
2015-09-19T01:59:11 < zyp> Bundestrojaner, I'd just look for a phototransistor with a higher gain, i.e. more drive current for a given irradiance
2015-09-19T01:59:12 < kakimir> but not this time
2015-09-19T01:59:25 < zyp> Bundestrojaner, perhaps some sort of darlington construction
2015-09-19T02:00:07 < Bundestrojaner> zyp: you mean driving a bc548 with a photo transistor?

2015-09-19T02:01:00 < zyp> oh, yeah, you can make the darlington construction yourself
2015-09-19T02:01:32 < zyp> I was thinking about finding one with it internally, but just adding another transistor should also help
2015-09-19T02:01:56 < Bundestrojaner> zyp: at first i'll try 2 in parallel
2015-09-19T02:02:16 < Bundestrojaner> would improve the positioning problem too

2015-09-19T02:06:14 < kakimir> if I do this trace width thing in application where impendance is not priority do I get away with it?
2015-09-19T02:06:24 < kakimir> *width transition
2015-09-19T02:06:41 < zyp> kakimir, what do you mean by width transition anyway?
2015-09-19T02:07:51 < kakimir> triangle type of thing
2015-09-19T02:09:13 < kakimir> from 2.Xmm to 0.Xmm
2015-09-19T02:11:34 < zyp> so what you're really saying is that you don't want to make a 50ohm impedance trace, because it would be too wide
2015-09-19T02:11:40 < kakimir> yes
2015-09-19T02:11:46 < kakimir> fukin huge
2015-09-19T02:12:01 < kakimir> and many of those
2015-09-19T02:12:12 < kakimir> and parts are smaller than trace
2015-09-19T02:12:52 < zyp> well, then you either have to do an impedance matching network to connect it to the 50ohm line or live with the effects of an impedance mismatch
2015-09-19T02:13:15 < zyp> what's the signal anyway? what connects to each end of this trace?
2015-09-19T02:15:00 < kakimir> there is
2015-09-19T02:16:04 < kakimir> sma in the other end and half bridge driver input in the other
2015-09-19T02:16:10 < kakimir> 8)
2015-09-19T02:16:35 < kakimir> don't say what you want to say
2015-09-19T02:16:48 < zyp> is this half bridge driver even a 50ohm impedance output?
2015-09-19T02:17:23 < kakimir> input
2015-09-19T02:17:31 < zyp> oh, input
2015-09-19T02:17:35 < zyp> well, is it 50ohm?
2015-09-19T02:17:55 < zyp> or are you just putting SMA on everything for show?
2015-09-19T02:19:26 < kakimir> there isn't really any reason not to
2015-09-19T02:20:34 < kakimir> I use em until I get bored
2015-09-19T02:20:37 < kakimir> then another thing
2015-09-19T02:20:43 < zyp> ok, then I'd suggest putting some sort of input buffer close to the sma, with a 50-ohm matched input
2015-09-19T02:21:19 < zyp> so the transmission line gets properly terminated and doesn't get reflections going back into the cable
2015-09-19T02:21:32 < zyp> then just run whatever width across the board
2015-09-19T02:22:28 < kakimir> yes that is obivious solution
2015-09-19T02:22:49 < zyp> or if you're only ever going to use it with short cable then fuck impedance matching at all
2015-09-19T02:22:57 < kakimir> but I want it to cost around 0<monetary unit>
2015-09-19T02:23:21 < kakimir> 20cm cable
2015-09-19T02:23:40 < zyp> heh
2015-09-19T02:25:08 < kakimir> there isn't reflection problems I guess
2015-09-19T02:25:18 < kakimir> as there is driver series resistor too
2015-09-19T02:25:23 < kakimir> ?
2015-09-19T02:27:05 < zyp> at 20cm the signal takes around a nanosecond to transition the cable, it'll hardly matter much
2015-09-19T02:29:01 < zyp> you'll get some ringing at the transitions, but it shouldn't matter much for the signal itself
2015-09-19T02:29:07 < kakimir> yes
2015-09-19T02:31:14 < Laurenceb_> hahah owned

2015-09-19T02:33:36 < kakimir> zyp: but if I stick to getting it right in principle

2015-09-19T05:24:13 < upgrdman> usa
2015-09-19T05:24:29 < upgrdman> 240v stuff uses it sometimes
2015-09-19T05:24:41 < upgrdman> high power stuff, like some cloths dryers, etc.
2015-09-19T05:24:44 < dongs> thats what my chinaoven 200V oplug looks like
2015-09-19T05:24:45 < kakimir> kind of australia/china but earth pin is weird
2015-09-19T05:25:11 < upgrdman> from here  https://www.reddit.com/r/Justrolledintotheshop/comments/3lgyag/this_is_why_i_never_trust_the_previous_tech/
2015-09-19T05:26:11 < upgrdman> it's a NEMA 10-30. rated for 240V 30A.  https://en.wikipedia.org/wiki/NEMA_connector#/media/File:NEMA_simplified_pins.svg
2015-09-19T05:26:46 < upgrdman> and hmm, welder makes more sense.
2015-09-19T05:27:30 < kakimir> what is main voltage in states is just a phase voltage here
2015-09-19T05:27:40 < kakimir> I wonder how serious tools are powered
2015-09-19T05:27:41 < upgrdman> 120V, but it's split phase
2015-09-19T05:28:00 < upgrdman> usa is 240V with center tap. most circuits are center tap + one "leg"
2015-09-19T05:28:02 < upgrdman> so 120V
2015-09-19T05:28:25 < upgrdman> kakimir, anything >1.5kW is ~always 240V
2015-09-19T05:28:37 < upgrdman> electric stove/oven, washer, dryer, big air conditioner, etc.
2015-09-19T05:29:02 < kakimir> how about 5kw workshop tools
2015-09-19T05:29:11 < kakimir> or more
2015-09-19T05:29:16 < upgrdman> i was kinda amused to find out that my 240V stove/oven uses WIRE NUTS instead of a plug.
2015-09-19T05:29:25 < upgrdman> kakimir, 240V
2015-09-19T05:30:11 < upgrdman> 240V 50A is the biggest i've seen, which would be 12kW
2015-09-19T05:31:10 < kakimir> and all phases of course?
2015-09-19T05:31:17 < kakimir> 3 phases*
2015-09-19T05:31:48 < upgrdman> not in residental. but for commercial/industrial, sure. and prolly offer >240V too
2015-09-19T05:31:52 < kakimir> oh only 2 in typical households
2015-09-19T05:32:04 < upgrdman> no. single phase for households
2015-09-19T05:32:18 < upgrdman> single phase, split. not two phases.
2015-09-19T05:33:17 < kakimir> we have 3phases for apartments
2015-09-19T05:33:26 < kakimir> 400V main voltages
2015-09-19T05:33:36 < kakimir> 230V phase voltages
2015-09-19T05:34:05 < kakimir> nowdays even flats have such because stoves and saunas

2015-09-19T05:48:36 < kakimir> fun thing about that italian socket is that you are about to charge your phone in the evening in your hotel room and try to plug charger and connector pitch doesn't match
2015-09-19T05:50:46 < kakimir> get adapter from reseption for 20eur
2015-09-19T05:53:05 < kakimir> are those holes in us plug really for connecting device with bare wires?
2015-09-19T05:53:21 < kakimir> in those flat pins
2015-09-19T05:54:11 < kakimir> just looked at socket and it seems to be for spring loading
2015-09-19T05:54:18 < kakimir> it into place
2015-09-19T06:02:35 < kakimir> oh wait that italian socket had too small holes for schuko
2015-09-19T06:05:45 < kakimir> for a laptop
2015-09-19T06:18:52 < upgrdman> kakimir, what about the holes in us plugs?
2015-09-19T06:18:59 < upgrdman> they're not for wires.
2015-09-19T06:19:15 < upgrdman> they're so little bulges in the receptable can key into the holes and securely hold the plug
2015-09-19T06:19:32 < upgrdman> e.g. so your heavy wall wart doesnt fall out easily
2015-09-19T06:24:17 < dongs> eh?
2015-09-19T06:24:29 < dongs> oh you mean the hoels in flat plug?
2015-09-19T06:24:34 < kakimir> yes
2015-09-19T06:24:45 < dongs> yea i always thought those were for threading wire  through it
2015-09-19T06:24:48 < dongs> when making a plug adapter
2015-09-19T06:24:54 < dongs> those dumb round plugs piss me off cuz y ou cant do that
2015-09-19T06:24:57 < dongs> when making adapter to a flat american plug
2015-09-19T06:25:11 < kakimir> freedom people can choose if have socket or connect directly
2015-09-19T06:25:17 < dongs> ya
2015-09-19T06:28:00 < upgrdman> dongs, i was serious. those holes are for better retention.
2015-09-19T06:28:50 < upgrdman> sad thing is many sockets dont have the bumps anymore, since it take a bit more effect to shape contacts instead of just bending them.
2015-09-19T06:29:13 < upgrdman> although, with transformer wall warts a thing of the past, you don't really need them anyway
2015-09-19T06:33:39 < dongs> ya i dont doubt it
2015-09-19T06:34:00  * emeb having fun converting F7 StdPeriph to HAL
2015-09-19T06:34:09 < dongs> why would you do that
2015-09-19T06:35:08 < emeb> because there is no StdPeriph for F7 - only HAL
2015-09-19T06:35:25 < emeb> so I take my old F4 StdPeriph code and migrate to HAL on F7
2015-09-19T06:35:53 < dongs> i would have imagined it would be easier to take what useful bits of F7 hal and fix them into stderpiph.
2015-09-19T06:36:17 < emeb> It's a bastard half-breed
2015-09-19T06:36:42 < emeb> HAL is a lot higher-level code and does a lot of things I'd rather do for myself
2015-09-19T06:36:49 < emeb> so I end up bypassing a lot of it.

2015-09-19T10:16:25 < Roklobsta> well i won't exceed that
2015-09-19T10:24:35 < jubatus> 25mA is probably short cicuit current
2015-09-19T10:24:59 < jubatus> if you want to maintain a decent voltage, it will be under 10mA

2015-09-19T10:40:06 < Ecco> hi :)
2015-09-19T10:41:08 < Ecco> PeterM: So you're saying that HobbyKings NiMH AA and AAA are very good then?
2015-09-19T10:41:39 < Ecco> I've bought a fair share of LiPo from them (to fly model airplanes). They were "meh", but incredibly cheap.
2015-09-19T10:48:23 < Sync> mine were not bad so far
2015-09-19T10:48:34 < Sync> low internal resistance and good capacity
2015-09-19T10:48:51 < Ecco> the ones I purchased were working great but eventually died pretty quickly
2015-09-19T10:50:32 < Sync> I got one in my motorcycle
2015-09-19T10:50:39 < Sync> survived two winters now
2015-09-19T10:50:44 < Ecco> LiPo?
2015-09-19T10:50:51 < Sync> yeah
2015-09-19T10:51:05 < Ecco> How do you charge it?
2015-09-19T10:51:32 < Sync> it just replaced the original battery
2015-09-19T10:53:29 < Sync> it's great, saves around 6kg above the CG
2015-09-19T10:53:46 < Ecco> I had no idea LiPos could be charged as Pb batteries
2015-09-19T11:02:38 < PeterM> Ecco, yeah their AAs and AAAs are very good value for money - i have bought them in bulk to be included with products i have made too
2015-09-19T11:03:41 < PeterM> their nimhs for model use are pretty average, but thats just a part of the technology, not hobbykings fault

2015-09-19T13:36:58 < Ecco> Hmm, I still can't figure out what would be the proper way to write a usleep function
2015-09-19T13:37:05 < Ecco> if I'm running bare-metal, without any RTOS
2015-09-19T13:38:23 < kakimir> is there even more than 1 way to do such?
2015-09-19T13:38:32 < Ecco> I have no idea :)
2015-09-19T13:38:43 < Ecco> I'm not talking about putting the device in a "deep" sleep mode
2015-09-19T13:39:00 < Ecco> I'm talking about "how do you wait a few msec without wasting energy"
2015-09-19T13:39:07 < kakimir> using one of timers to interupt sleep
2015-09-19T13:39:42 < kakimir> which one you use and how you do it it's technical detail
2015-09-19T13:39:48 < Ecco> ok
2015-09-19T13:39:55 < Ecco> then I guess I have to "wait for interrupt"?
2015-09-19T13:40:17 < Ecco> so that my sleep routine looks like "1/ Setup timer, 2/ Wait for timer to expire"
2015-09-19T13:40:28 < kakimir> if you have excess timer just get that to use
2015-09-19T13:40:39 < Ecco> no comprendo

2015-09-19T13:42:27 < kakimir> yes next after function that enters core into sleep is function to be called after wakeup
2015-09-19T13:42:38 < Ecco> ok :)
2015-09-19T13:42:41 < kakimir> there is no loops or anything
2015-09-19T13:42:51 < Ecco> Yes I understand
2015-09-19T13:42:59 < Ecco> Can this be done in C?
2015-09-19T13:43:04 < Ecco> Or do I need assembly?
2015-09-19T13:43:20 -!- PaulFertser [paul@paulfertser.info] has joined ##stm32
2015-09-19T13:43:31 < kakimir> I bet you don't need assembly
2015-09-19T13:43:35 < Ecco> ok
2015-09-19T13:43:40 < Ecco> how do I generate the WFI instruction?
2015-09-19T13:45:57 < kakimir> hmm
2015-09-19T13:46:39 < Roklobsta> dunno.  i did a simple preeptive scheduler for the AVR that went into sleep mode during the idle task.  Pretty easy to do.  Not having done ARM *yet* I'd expect it to be the same process though, going into sleep mode then using a timer IRQ to wake up.
2015-09-19T13:47:09 < Ecco> ok
2015-09-19T13:47:28 < kakimir> if it's actual arm instruction you may enter it in inline asm function but I bet there is something to use for power modes in headers or HAL if such used
2015-09-19T13:48:40 < kakimir> someone who have done power modes with cortex would know better
2015-09-19T13:48:44 < obsrwr> any of you guys ever used a BusPirate 3.6 on linux?
2015-09-19T13:48:49 < obsrwr> I think the one i have is fried
2015-09-19T13:48:53 < Ecco> I have
2015-09-19T13:48:57 < Ecco> well, on OS X
2015-09-19T13:48:59 < obsrwr> i connect it to the laptop but linux doesn't enumerate it
2015-09-19T13:49:02 < Ecco> but it's pretty similar
2015-09-19T13:49:04 < obsrwr> the PWR led is on
2015-09-19T13:49:05 < Ecco> Does it light up?
2015-09-19T13:49:06 < obsrwr> but that's about it
2015-09-19T13:49:09 < Ecco> hmm, weird
2015-09-19T13:49:15 < Roklobsta> You're right, WFI.  ARM made this easy.  http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0497a/BABHHGEB.html
2015-09-19T13:49:19 < Ecco> Probably dead indeed
2015-09-19T13:49:29 < obsrwr> alright, thanks Ecco
2015-09-19T13:49:51 < Ecco> when you plug it in, dmesg doesn't say anything?
2015-09-19T13:49:56 < obsrwr> nothing at all
2015-09-19T13:50:05 < Ecco> That's weird
2015-09-19T13:50:07 < obsrwr> and i even recompiled the kernel with all USB serial options i could find
2015-09-19T13:50:19 < Ecco> Do you have any other machine lying around?
2015-09-19T13:50:35 < obsrwr> i tried it on an ibm thinkpad running arch linux
2015-09-19T13:50:37 < obsrwr> same
2015-09-19T13:50:44 < Ecco> ok
2015-09-19T13:50:52 < Ecco> on OS X it works out of the box
2015-09-19T13:50:57 < Ecco> I guess it should on linux as well
2015-09-19T13:50:59 < obsrwr> it should on linux as well
2015-09-19T13:51:04 < Ecco> it *definitely* should be enumerated
2015-09-19T13:51:09 < zyp> if dmesg doesn't say anything at all, the device isn't signalling presence with a pullup on d+

2015-09-20T05:41:23 < upgrdman> very badly
2015-09-20T05:42:01 < upgrdman> irs21867s gate driver
2015-09-20T05:42:22 < upgrdman> it gets warmer than the normal fet. i wonder if im using the fet wrong
2015-09-20T05:42:44 < upgrdman> since im having conventional current go from source to drain.
2015-09-20T05:43:04 < upgrdman> but i am driving the gate 12V above source to turn it on
2015-09-20T05:43:33 < upgrdman> "it gets warmer" referred to the high side fet, not the gate driver

2015-09-20T05:44:47 < PeterM> ok, a few things to help
2015-09-20T05:45:10 < PeterM> 1) got a diode in parallel with it? a schoittky diode will stop the body diode turning on
2015-09-20T05:45:26 < PeterM> and will stop the current from flowing through it when the fet turns off
2015-09-20T05:45:28 < upgrdman> it's a avalanche-rated FET with power diode inside
2015-09-20T05:45:33 < PeterM> link?
2015-09-20T05:46:08 < PeterM> if the diodes reverse recovery is crap it wont help
2015-09-20T05:46:44 < upgrdman> http://pdf.datasheetcatalog.com/datasheet/toshiba/2986.pdf
2015-09-20T05:46:50 < PeterM> 2) are you jsut driving it out of phase with your boost fet?
2015-09-20T05:46:57 < upgrdman> yes
2015-09-20T05:47:27 < PeterM> you should ideally be driving it with zero crossing detection so current doenst flow backwards through it to ground after the coupled current
2015-09-20T05:48:33 < upgrdman> oh shit ya. lol.
2015-09-20T05:48:39 < upgrdman> totally didn't think of that.
2015-09-20T05:49:08 < PeterM> i think i mentioned it to you but you didnt notice
2015-09-20T05:49:32 < upgrdman> prolly
2015-09-20T05:51:30 < PeterM> also, the reverse recovery on that fets diode is pretty slow, you want a schottky or a high speed silicon diode, they have 0-4ns reverse recovery, compared to the 60ns of the fet
2015-09-20T05:51:55 < upgrdman> k
2015-09-20T05:51:55 < PeterM> they don't have to be high continuous current because your fet will be doign the heavy lifting, but they need to be pulse rated
2015-09-20T05:57:26 < PeterM> also, what voltage are you driving the gate with? if you're driving it with more than the minimum voltage of that driver you're probably just wasting power and probably also slowing down switching
2015-09-20T05:58:19 < upgrdman> driver is rated for 5-20V
2015-09-20T05:58:23 < upgrdman> im using 6V
2015-09-20T05:58:23 < PeterM> the more charge you put into the  gate the mroe you have to take out
2015-09-20T05:58:27 < PeterM> 6v is good
2015-09-20T05:58:47 < PeterM> i thought you mi9ght be using 12 or so (which is pretty standard)
2015-09-20T05:58:58 < PeterM> 6-8 is optimal imho
2015-09-20T05:59:03 < upgrdman> well correction: 6v for low side fet
2015-09-20T05:59:18 < upgrdman> high side boost voltage gets very high, and i clamp it to 12v to a zener
2015-09-20T06:00:24 < upgrdman> *12v above high-side source. not 12v from ground.
2015-09-20T06:00:32 < PeterM> yeah
2015-09-20T06:00:33 < PeterM> ofc
2015-09-20T06:02:18 < PeterM> but yeah, those two things should make the fet a bit cooler, should also make your converter more efficient
2015-09-20T06:03:41 < upgrdman> ya
2015-09-20T06:04:16 < PeterM> how much dissipation would you guess your fet has? 1-2w or more?

2015-09-20T06:05:08 < upgrdman> maybe. not really good at est'ing that.
2015-09-20T06:05:50 < PeterM> use a heatsink with known dissipation, measure temp, approximate power
2015-09-20T06:05:55 < upgrdman> heatsinks gets about as hot as i'd expect with a 3w led... so prolly around there
2015-09-20T06:06:17 < upgrdman> ya, about that... i just use heatsinks from shit pc's or other stuff that's getting thrown away
2015-09-20T06:06:17 < PeterM> mmhm
2015-09-20T06:07:34 < PeterM> you can still approximate thermal conductivity though, just digikey for a similar size/shape heatsinks and look at its numebrs, - provided its the same materials it should be atleast i nthe same ballpark

2015-09-20T06:15:27 < upgrdman> well they get to about 150F with 73F ambient... so 83F is ~28C
2015-09-20T06:16:11 < upgrdman> err 77F, so 25C
2015-09-20T06:16:31 < upgrdman> so that's 1w :)
2015-09-20T06:16:33 < PeterM> its to reset the transformer core to stop it saturating over time

2015-09-20T06:26:00 < PeterM> aandrew, they aren't *that* bad, it's just that they are "real" electronics opposed to embedded electronics
2015-09-20T06:26:19 < aandrew> oh I agree
2015-09-20T06:27:11 < aandrew> I designed a couple of them over the years. I'm not very good at it. that third winding is the magic
2015-09-20T06:29:42 < upgrdman> well this sepic project has already been worth while for me. forced me to finally learn a bit about RLC circuits. when i bumped up to 125kHz PWM, and the 4A gate driver, i got some awesome ringing on the gates:  http://www.farrellf.com/temp/sepic_fast_pwm_ringing.png    :D
2015-09-20T06:30:00 < PeterM> JESUS FUCK
2015-09-20T06:30:07 < upgrdman> >:)
2015-09-20T06:30:14 < PeterM> you need soem termination there
2015-09-20T06:30:21 < PeterM> or shorter leads
2015-09-20T06:30:23 < PeterM> or both
2015-09-20T06:30:25 < upgrdman> i know. both
2015-09-20T06:30:38 < aandrew> is that real ringing? how long are your grounds?
2015-09-20T06:31:24 < upgrdman> yes. i even probed with a spring ground, and it only cleaned up a little
2015-09-20T06:31:44 < upgrdman> note that that screenshot has all four channels limited to 20MHz bandwidth :) :)
2015-09-20T06:32:02 < PeterM> it looks real because it doesn't just show o nthe gate, but also shows on the signal switched by the fet
2015-09-20T06:32:24 < upgrdman> ya
2015-09-20T06:32:54 < upgrdman> yellow = low side gate         dark blue = high side gate            light blue = high side source          magenta = output voltage
2015-09-20T06:33:12 < aandrew> I see ringing on all the lines
2015-09-20T06:33:25 < PeterM> indeed
2015-09-20T06:34:06 < upgrdman> most of it seems to be from wires for the gate driver.
2015-09-20T06:34:18 < upgrdman> it was even worse with the longer wires shown in the RevA photo
2015-09-20T06:34:30 < upgrdman> i cut them to half the length and it cleaned up noticably
2015-09-20T06:35:08 < PeterM> i wouldnt be surprised if the fet was gettign super hot when you first tried it
2015-09-20T06:35:40 < upgrdman> prolly
2015-09-20T06:36:24 < upgrdman> i measure about 80nH per wire going between fet / driver, and about 50mOhm or resistance per wire
2015-09-20T06:36:34 < upgrdman> sim'd in ltspice... and looks just like my scope

2015-09-20T06:37:26 < upgrdman> PeterM, in my sim it looks like 5 ohm termination resistors would helps a lot. why? is it because it keeps the parasitic inductors "saturated" ?
2015-09-20T06:37:29 < PeterM> that fet is pretty huge (unnessecaryily[sp?] so)

2015-09-20T06:42:15 < upgrdman> PeterM, for more "jesus fuck", here's some waveforms from a 100W boost converted i was similarly half-ass-prototyping a year ago: http://www.farrellf.com/temp/adjustable_load.jpg
2015-09-20T06:49:39 < PeterM> it limits the risetime from the inductor once the cap is charged, since the risetime is limited it requires a much bigger capacitor to resonate with, but also, if it did have a bigger capacitor, it wouldn't resonate much anyway because the resistor would dissipate out the energy (the amount of energy stored inthe inductance of the wire would be tiny)
2015-09-20T06:50:25 < PeterM> what was that boost converter?
2015-09-20T06:51:57 < upgrdman> something i designed, very poorly (my first SMPS) for a 100W china led
2015-09-20T06:52:35 < upgrdman> 12V boosted to 35ish V
2015-09-20T06:53:37 < PeterM> i dont think that would have looksed so bad on the scop if you probed it properly and you had all your leads short etc
2015-09-20T06:54:12 < upgrdman> ya
2015-09-20T06:54:29 < upgrdman> i etched a pcb and ~all noise went away
2015-09-20T06:54:55 < PeterM> also, for fixed constant current, in higher voltage supplies you can be pretty lazy
2015-09-20T06:55:09 < upgrdman> but i didnt use proper current sensing, just a resistor, so the stm adc only had a few hundred counts to work with, and was noisey as fuck, so the feedback loop was not stable.
2015-09-20T06:55:35 < upgrdman> well it would "flicker"
2015-09-20T06:55:51 < upgrdman> if i would have used a current amp and proper shunt, im sure i could have made it work quite nicely

2015-09-20T06:59:17 < PeterM> with a stnadard boost converter ic, you could jsut put in a low side current shunt of the appropriate value and fed that straight to the feedback pin - say 0.38ohm, would give 1.25v~ @ 3.33A~
2015-09-20T07:00:01 < PeterM> love that fuse holder
2015-09-20T07:00:02 < PeterM> lol
2015-09-20T07:01:10 < PeterM> is that stack of 4 resistors your shunt?
2015-09-20T07:01:23 < upgrdman> PeterM, ya. it looks super ghetto because i made it over a 3 day weekend (layout to etch to populate to test) and only bought the fuse. everything else was laying around or pulled from random trash
2015-09-20T07:01:41 < upgrdman> PeterM, the four was for input current sensing, but i fucked it up, so couldn't use it
2015-09-20T07:01:53 < upgrdman> the one power resistor is for low side current sensing.
2015-09-20T07:02:20 < PeterM> ahh yep

2015-09-20T08:54:16 < upgrdman> aandrew, re: laminator. the $20 one i use is good for my application, but it's like the cheapest piece of shit you can get away with.
2015-09-20T08:54:41 < upgrdman> there's much better ones that support more temps, heat up/stay hot better, etc.

2015-09-20T08:55:32 < upgrdman> and it prolly cost like $3 to make. it's just a pair of rollers, some heating element, and what looks like a 555 + triac or equiv
2015-09-20T08:55:52 < upgrdman> + geared AC motor to move the rollers
2015-09-20T08:56:45 < dongs> what's innovating
2015-09-20T08:57:01 < upgrdman> my sepic is LOL-worthy

2015-09-20T08:57:21 < dongs> i bet it would cost less to just use a proper contorller

2015-09-20T19:53:59 < upgrdman> they wont? wow. that sux
2015-09-20T19:54:44 < dongs> yeah, beacuse me making a fake usa paypal with non-existent address and shit is safer then allowing international buyers
2015-09-20T19:55:09 < dongs> newegg gladly ships to unconfirmed address thats not even on file with my fakepaypal.
2015-09-20T19:55:11 < upgrdman> *nods*

2015-09-20T20:50:56 < upgrdman> looks like it should be fun to fly tho

2015-09-20T20:51:07 < zyp> upgrdman, uh, your dick sounds kinda weird
2015-09-20T20:51:30 < upgrdman> right
2015-09-20T20:51:58 < upgrdman> when i first looked at the second photo, i thought the arms were like 10mm thick. then i realized theyre just landing pads at the ends.

2015-09-20T21:14:48 < upgrdman> yes. yes it is.
2015-09-20T21:15:05 < ReadError> pretty much
2015-09-20T21:17:35 < Steffanx> personal preferences?
2015-09-20T21:19:03 < upgrdman> easystar
2015-09-20T21:19:30 < upgrdman> dont buy a kit if your a noob
2015-09-20T21:19:38 < upgrdman> that first link is an easystar clone
2015-09-20T21:21:04 < upgrdman> R2COM, kits dont come with electronics usally, and also assume you know what youre doing. so very little advise, if any, in the manual
2015-09-20T21:21:16 < upgrdman> first
2015-09-20T21:21:20 < upgrdman> if its RTF
2015-09-20T21:21:35 < upgrdman> ready to fly
2015-09-20T21:21:38 < upgrdman> and looks like its not
2015-09-20T21:21:43 < upgrdman> you need to provide your own radio and lipo
2015-09-20T21:21:48 < upgrdman> gay
2015-09-20T21:21:53 < upgrdman> gimma a sec
2015-09-20T21:22:10 < upgrdman> true
2015-09-20T21:22:32 < upgrdman> but if you need it all, and dont have preferences for quality, it much cheaper to buy RTF than piece meal
2015-09-20T21:22:52 < upgrdman> ok sure, if you plan to be in RC for a while, definitely buy a nice one
2015-09-20T21:23:12 < upgrdman> if you're not sure... but a cheap RTF and see if RC is for you
2015-09-20T21:23:20 < upgrdman> not the second. it's a kit.
2015-09-20T21:23:49 < upgrdman> also, balsa models are more of a pain to repair. and you
2015-09-20T21:24:01 < upgrdman> also, balsa models are more of a pain to repair. and you're a noob, so you will crash it on your first day out
2015-09-20T21:24:18 < upgrdman> foam is MORE durable that wood is most cases
2015-09-20T21:24:28 < upgrdman> also foam is fucking trivial to fix
2015-09-20T21:24:52 < upgrdman> no you get foam-safe ca, foam-safe accelerator... and like two seconds and it's glued back together and ready to fly
2015-09-20T21:24:58 < zyp> I remember one of my friends bought a cheap rtf plane
2015-09-20T21:25:13 < zyp> after a few flights, it was more glue than foam
2015-09-20T21:25:26 < upgrdman> ya you're going to crash almost immediately. and thats ok, but realize it.
2015-09-20T21:26:39 < upgrdman> R2COM will do this: https://www.youtube.com/watch?v=3hpv6N5ly0I
2015-09-20T21:26:54 < upgrdman> R2COM, no it can be lighter. because its mostly hollow air cavities
2015-09-20T21:27:08 < upgrdman> balsa is often better, but more of a bitch to fix
2015-09-20T21:28:24 < upgrdman> R2COM, and i know you don't want to hear this, but seriously: buy one of the RC flight sims. with a fake transmitter. it helps a fuck ton. and no, your flight sim games do not compare.
2015-09-20T21:28:53 < ReadError> R2COM you can get a bixler

2015-09-20T21:30:48 < upgrdman> BUY ONE WITH A FAKE TRANSMITTER

2015-09-20T21:31:11 < ReadError> ya
2015-09-20T21:31:16 < upgrdman> but you need it if you don't want to crash non stop in real life
2015-09-20T21:31:40 < upgrdman> i have the Phoenix Sim, but i use my own real transmitter with it
2015-09-20T21:31:46 < upgrdman> realflight is very nice too
2015-09-20T21:31:50 < upgrdman> i have only flown those two
2015-09-20T21:32:19 < upgrdman> you plug a dongle into the tx trainer port
2015-09-20T21:32:26 < upgrdman> and a usb dongle plugs into that dongle

2015-09-20T22:23:03 < ReadError> englishman ya but for the price its not bad

2015-09-20T22:26:53 < englishman> 1st is no rx 3rd is with rx

2015-09-20T22:51:33 < englishman> this is video transmitter
2015-09-20T22:51:44 < englishman> i used this one at 4km with the stupid antenna it comes with

2015-09-20T22:54:18 < englishman> http://www.myrcmart.com/rc-accessories-fpv-first-person-view-c-22_333.html
2015-09-20T22:54:23 < englishman> a pal bought some of these screens
2015-09-20T22:54:25 < englishman> should be good
2015-09-20T22:54:38 < ReadError> screens lack the immersionrc
2015-09-20T22:54:40 < englishman> "snowflake screen" means you see static instead of bluescreen
2015-09-20T22:54:49 < englishman> cuz bluescreening is annoying as fuck as signal drops
2015-09-20T22:55:46 < englishman> right
2015-09-20T22:55:49 < englishman> but
2015-09-20T22:55:55 < englishman> notice that your rc is 2.4g
2015-09-20T22:56:00 < englishman> so using 2.4g video is a nogo
2015-09-20T22:56:01 < englishman> rite
2015-09-20T22:56:17 < englishman> the video tx knocks out your rc rx
2015-09-20T22:56:25 < englishman> so your shit will fall out of the sky at 50ft
2015-09-20T22:56:28 < englishman> ask how we know
2015-09-20T22:56:40 < englishman> which is why 5.8g video is mega popular

2015-09-20T23:08:51 < upgrdman> it needs DC input tho. so car battery, or lab psu or atx psu
2015-09-20T23:15:12 < karlp> foam is bouncy enough to land on grass

2015-09-21T00:56:24 < upgrdman> the gimbals on futaba radios feel nice to me.
2015-09-21T00:56:28 < upgrdman> yes
2015-09-21T00:56:35 < upgrdman> the sticks... are on gimbals
2015-09-21T01:03:09 < upgrdman> going hard is easy
2015-09-21T01:03:14 < upgrdman> you can change springs
2015-09-21T01:03:38 < upgrdman> and if you like stiff gimbals, you wont mind the cheap radio so much.
2015-09-21T01:03:52 < upgrdman> most of the quality goes into making them feel smoother, which you wouldnt notice as much

2015-09-21T01:23:56 < Laurenceb__> but SEPIC will bite you in the ass if you dont get it 100% right
2015-09-21T01:24:02 < upgrdman> http://www.farrellf.com/temp/sepic_fast_pwm_ringing.png
2015-09-21T01:24:02 < Laurenceb__> heh what upgrdman said
2015-09-21T01:24:17 < Laurenceb__> heh I've seen that
2015-09-21T01:24:25 < Laurenceb__> mine issue was layout related
2015-09-21T01:24:27 < Laurenceb__> *my
2015-09-21T01:24:37 < upgrdman> my issue is 6" leads for gate/source
2015-09-21T01:24:44 < upgrdman> because im doing a ghetto prototype
2015-09-21T01:24:49 < Laurenceb__> lol
2015-09-21T01:24:57 < Roklobsta> kill the parasites.  with DDT.
2015-09-21T01:24:59 < Laurenceb__> I had parasitic inductance on a PCB
2015-09-21T01:25:26 < Laurenceb__> also SPICE is your friend
2015-09-21T01:25:27 < upgrdman> long traces?
2015-09-21T01:25:28 < Roklobsta> try follow the layout guide on the data sheet
2015-09-21T01:25:30 < BrainDamage> on my dcdc i get ringing even just from the scope probes if i don't use the spring clip
2015-09-21T01:25:54 < Laurenceb__> SPICE everything with the most accurate models you can find
2015-09-21T01:26:16 < Roklobsta> then add low esr caps.
2015-09-21T01:26:18 < upgrdman> ya i was able to duplicate my waveforms in ltspice
2015-09-21T01:26:44 < upgrdman> it doesn't help that my fets have FUCK TONS of input capacitance. almost 10nF
2015-09-21T01:27:05 < Roklobsta> i am surprised ltspice ever agreed to run. 'You want me to model this!?...'
2015-09-21T01:27:21 < BrainDamage> you can force sims to like dcdc
2015-09-21T01:27:34 < BrainDamage> like explicitly adding cap loading to switch nodes
2015-09-21T01:27:47 < BrainDamage> so that during small timesteps it never ends up floating
2015-09-21T01:27:56 < Roklobsta> upgrdman: can you add a another fet driver?
2015-09-21T01:27:57 < upgrdman> i learned that ltspice will gladly simulate PWM with zero rise/fall time... by assigning some rise/fall time of its choosing. instead of warning like a good tool should
2015-09-21T01:28:18 < upgrdman> Roklobsta, my gate driver isn't the problem. it can do 4A
2015-09-21T01:28:25 < upgrdman> the problem is 6" flying wires
2015-09-21T01:28:34 < Roklobsta> yeah, i have fixed it in the past with forcing Tstep and Trise/fall like you did
2015-09-21T01:29:06 < Roklobsta> well
2015-09-21T01:29:18 < Roklobsta> nothing like a short wide trace and a big fat groundplane
2015-09-21T01:32:22 < upgrdman> i still dont know how to pick the capacitance of a SEPICs coupling cap.
2015-09-21T01:32:54 < Roklobsta> upgrdman: bastard, what rigol is that?

2015-09-21T03:54:05 < upgrdman> fuel mix was approximately: 30% nitromethane, 18% synthetic oil, 52% methanol
2015-09-21T03:54:28 < upgrdman> actual gasoline is very rare except for the VERY big models
2015-09-21T03:54:45 < upgrdman> because the engines are VERY heavy for the amount of power they produce, compared to nitro or elec
2015-09-21T03:54:55 < upgrdman> magneto or CDI also adds weight
2015-09-21T03:55:37 < upgrdman> here's the inside of a 0.39 cubic inch nitro engine i had:  http://www.rcheliguy.com/images/temp_tt39h/

2015-09-21T03:56:13 < upgrdman> that one had a bad con rod that gal'd to the crankshaft before getting a gallon of fuel through it
2015-09-21T03:56:44 < upgrdman> gas = gasoline
2015-09-21T03:56:46 < upgrdman> glow = nitro
2015-09-21T03:57:31 < upgrdman> they call them glow because they use glow plugs instead of spark plugs. and technically you dont need nitromethane, can run on just oil/methanol, but then they're weak little pussy engines
2015-09-21T03:58:01 < upgrdman> iirc only the europenas run glow engines on 0% nitro, because of cost or regulations

2015-09-21T04:02:44 < upgrdman> for big models, gas. by far.
2015-09-21T04:02:45 < fenugrec> glow burn fuel like there's no tomorrow
2015-09-21T04:02:54 < upgrdman> elec flight times are often <15 mins
2015-09-21T04:03:03 < upgrdman> nitro flight times are 10 - 30 mintues
2015-09-21T04:03:09 < upgrdman> gas can be over an hour if you want
2015-09-21T04:04:03 < upgrdman> yes
2015-09-21T04:04:07 < upgrdman> also gas is more dangerous
2015-09-21T04:04:28 < upgrdman> gasoile burns hotter. can start fires if you do stupid shit like rest fuel line on your exhaust pipe

2015-09-21T04:05:49 < upgrdman> R2COM, but stick with electric for your first model(s)
2015-09-21T04:05:58 < upgrdman> tuning an engine is just another thing you can fuck up

2015-09-21T04:11:46 < upgrdman> its a 30-60 min drive to the flying field (can't fly nitro in your backyard...) and the local fields got popular and overcrowded
2015-09-21T04:11:52 < upgrdman> i hate flying near other people
2015-09-21T04:13:45 < upgrdman> most parks prohibit anything rc
2015-09-21T04:13:54 < upgrdman> i would fly at legic RC flying sites.
2015-09-21T04:14:01 < upgrdman> like, with paved runways.
2015-09-21T04:14:22 < upgrdman> you joing the "club" and pay like $100/yr, and you get a key to the gate.
2015-09-21T04:15:00 < upgrdman> for little electric toys, you can prolly get away with flying in a big park if you dont bother people
2015-09-21T04:15:38 < upgrdman> if you live in a rich area, expect dumb cunts to come up to you and bitch about how you're endangering them

2015-09-21T04:16:14 < upgrdman> ya
2015-09-21T04:16:32 < upgrdman> most clubs require AMA insurance. which is like $50/year RC liability insurance
2015-09-21T04:16:45 < upgrdman> so if your toy kills someone, there's some insurance
2015-09-21T04:17:04 < upgrdman> more likely, so if you crash into someones car and scratch the paint...
2015-09-21T04:20:23 < upgrdman> yes
2015-09-21T04:20:26 < upgrdman> and follow rules
2015-09-21T04:20:46 < upgrdman> e.g. no insurance coverage if you drink alcohol, etc.
2015-09-21T04:24:54 < upgrdman> i think you can? float planes are common in areas with bodies of water
2015-09-21T04:27:10 < upgrdman> i think AMA covers you any time you abide by their rules, so long as you are not also violating any local rules or laws
2015-09-21T04:27:22 < upgrdman> ama has docs covering their rules on their web site
2015-09-21T04:33:33 < upgrdman> right
2015-09-21T04:35:21 < zyp> there's limits to how much you can hurt somebody with an RC craft :p

2015-09-21T04:38:09 < upgrdman> Roklobsta, if you loose orientation AND are dumb enough to be flying close to yourself
2015-09-21T04:39:47 < upgrdman> e.g you fly behind a tree (or anything else) by accident and momentarily look track of the model
2015-09-21T04:41:25 < upgrdman> R2COM, and this is something you should practice with the rc flight sim. like look away from your screen for 3 seconds, then look back and try to regain control
2015-09-21T04:41:51 < upgrdman> not such a big deal with planes, but still helpful
2015-09-21T04:43:06 < upgrdman> unless you loose signal :)

2015-09-21T04:47:25 < upgrdman> and if it did, it would just keep your head in tact, but the force would likely break your spinal cord or other goodies

2015-09-21T04:54:50 < upgrdman> R2COM, https://youtu.be/qQ9dSrrBN28?t=53
2015-09-21T04:55:03 < upgrdman> also, turbine rc models crash just like the real ones. HUGE fire ball.
2015-09-21T04:56:14 < upgrdman> crash:  https://www.youtube.com/watch?v=Aajp-A43glA

2015-09-21T04:59:09 < upgrdman> no
2015-09-21T04:59:16 < upgrdman> but there is a woman's prison up the road
2015-09-21T04:59:28 < kakimir> oh
2015-09-21T05:00:46 < upgrdman> >$15K iirc
2015-09-21T05:00:49 < upgrdman> rich boy toys
2015-09-21T05:01:12 < kakimir> jet engines from 2000$ smallest ones
2015-09-21T05:01:23 < upgrdman> engine is but a small cost
2015-09-21T05:01:24 < kakimir> up to.. 10k ?
2015-09-21T05:01:34 < upgrdman> for those models, you often need high quality electronics

2015-09-21T05:01:46 < upgrdman> don't be surprised to pay $150+ per servo, etc.
2015-09-21T05:02:01 < upgrdman> at high speeds, you really dont want your control surfaces fluttering, etc.
2015-09-21T05:02:02 < kakimir> or more
2015-09-21T05:02:22 < upgrdman> R2COM, for anything bigger than a backyard toy, yes
2015-09-21T05:03:33 < upgrdman> just less likely to run into people bitching
2015-09-21T05:03:45 < upgrdman> and you can make friends with like minded people
2015-09-21T05:04:15 < upgrdman> bigger clubs often offer free rc flight lessons
2015-09-21T05:07:36 < upgrdman> it would be awesome if ##stm32 did a meetup.
2015-09-21T05:08:06 < upgrdman> we could all call eachother fags in real life, etc.
2015-09-21T05:08:35 < kakimir> I thought feminists had their own institution and runway
2015-09-21T05:08:41 < kakimir> that would have been bad
2015-09-21T05:09:44 < upgrdman> i remember being there one time when there was a prison break and one girl got out. police helicopter flying LOW and combing the area. we all kinda stood there with a mix of WTF/aweome!

2015-09-21T05:17:19 < upgrdman> ya
2015-09-21T05:17:24 < upgrdman> play on a sim first
2015-09-21T05:17:31 < upgrdman> it will save you LOTS of time and money
2015-09-21T05:17:40 < upgrdman> and give you some confidence for your first flight
2015-09-21T05:18:01 < fenugrec> most discouraging hobby eva
2015-09-21T05:19:12 < kakimir> my first rc plane 500eur ducted fan
2015-09-21T05:19:30 < upgrdman> because RC is a hobby with "strings attched"
2015-09-21T05:19:35 < upgrdman> you need to fly during the day
2015-09-21T05:19:57 < upgrdman> you need to fly when the wind isn't too high (but flying in the wind is fun!)
2015-09-21T05:20:10 < kakimir> I think I move completelly to DLG
2015-09-21T05:20:15 < upgrdman> i need to fly where there aren't many people (or else i dont find it fun)
2015-09-21T05:20:21 < kakimir> keeps blood pumping
2015-09-21T05:20:36 < upgrdman> so RC just become more of a hassle
2015-09-21T05:20:52 < upgrdman> with electronics as a hobby... i can do anytime i damn well please
2015-09-21T05:21:00 < upgrdman> day, night, rain, wind, holidays...
2015-09-21T05:21:47 < upgrdman> if i even move out into the "country" and have a plot of open land... i will have a HOUSE FULL of rc toys
2015-09-21T05:23:02 < upgrdman> no
2015-09-21T05:23:07 < upgrdman> i sold ~all of my rc stuff
2015-09-21T05:23:26 < upgrdman> im down to two 450 size electric helis, and two small indoor quads
2015-09-21T05:23:48 < upgrdman> because i dont want to drive an hour to the flying field, show up to a packed field, and not enjoy the day?
2015-09-21T05:24:05 < upgrdman> i live in so cal. not really any open plots of land. i have to go out of my way to do it
2015-09-21T05:24:27 < upgrdman> ya
2015-09-21T05:24:45 < upgrdman> its like a bike. i can fly on the sim just fine.
2015-09-21T05:25:02 < upgrdman> will take a bit of practice to clean up my skills, but you don't forget how to fly
2015-09-21T05:27:00 < upgrdman> that was one of the saddening parts of my trip to china. despite the pop density of shanghai, in the industrial zones, theres tons of open land. i would have loved to fly rc over there.
2015-09-21T05:44:31 < kakimir> are cali kids okay?
2015-09-21T05:44:31 < upgrdman> kinda
2015-09-21T05:44:38 < upgrdman> but im fat, so don't bike very much
2015-09-21T05:44:58 < kakimir> or are they like on drugs and all that
2015-09-21T05:45:14 < upgrdman> kakimir, just like everthing else, there's a bell curve
2015-09-21T05:45:25 < upgrdman> usually it's the poor ones that are drug addicts
2015-09-21T05:45:37 < emeb_mac> usually
2015-09-21T05:45:40 < upgrdman> in my area, that means the black people (no joke)
2015-09-21T05:45:40 < emeb_mac> not always
2015-09-21T05:46:13 < emeb_mac> rich kids in scottsdale have a higher incidence of heroin use than the poorer neighborhoods
2015-09-21T05:46:26 < upgrdman> seems like ~all of the trouble makers in my neighborhood are black. super annoying. BUT there's also lots of blacks that are wonderful or no problem
2015-09-21T05:47:51 < upgrdman> its kinda funny. there's a driver way with a gate to get into my community. when i pull into the driveway and use my remote to open the gate, if there's any black kids around, they look intensely to make sure im not some rival gang member or some shit
2015-09-21T05:48:07 < upgrdman> white kids? no fucks given.
2015-09-21T05:48:50 < upgrdman> mexian kids? no fucks given either.
2015-09-21T05:48:57 < upgrdman> lol
2015-09-21T05:49:07 < upgrdman> asian kids? no fucks given either.
2015-09-21T05:49:20 < kakimir> communities with gates :oo
2015-09-21T05:49:39 < upgrdman> kakimir, its mostly a joke. but it keeps random idiots out
2015-09-21T05:49:41 < upgrdman> like bums
2015-09-21T05:49:43 < upgrdman> and salemen
2015-09-21T05:49:46 < upgrdman> salemen
2015-09-21T05:49:50 < upgrdman> err salesmen
2015-09-21T05:50:10 < kakimir> I would pay for that
2015-09-21T05:50:11 < upgrdman> dont have many of those in this city
2015-09-21T05:50:33 < upgrdman> in rich cities, i would get jahovahs witnesses knocked on my door like once a month
2015-09-21T05:50:40 < englishman> Gated ghettos astound me whenever I go to americaland
2015-09-21T05:50:44 < englishman> There are so many
2015-09-21T05:50:48 < englishman> Its like nicaragua
2015-09-21T05:51:04 < upgrdman> gates ghettos?
2015-09-21T05:51:10 < upgrdman> like poor people inside the gates?
2015-09-21T05:51:13 < englishman> Ya like your place
2015-09-21T05:51:28 < englishman> Community, call it what you will
2015-09-21T05:51:35 < upgrdman> my place is actually kinda nice. it's just surrounded by shit. its like an oasis
2015-09-21T05:51:53 < englishman> Put up walls to keep the darkies out
2015-09-21T05:52:06 < upgrdman> whenever a new pizza delivery guy comes to my door, he seems amazed by the quality of my place. water fountain in the middle, etc.
2015-09-21T05:52:45 < upgrdman> englishman, it's not like that here. we have "darkies" in my place too. and outside it.
2015-09-21T05:53:04 < upgrdman> the gates aren't to separate races. they're to keep bums away
2015-09-21T05:53:40 < kakimir> there is no gated communities in here
2015-09-21T05:53:50 < englishman> That's fucked up, I don't even lock my doors
2015-09-21T05:53:59 < kakimir> never seen even one
2015-09-21T05:54:13 < upgrdman> ya i live in an area where you lock your doors, but would not expect anyone to try getting in.
2015-09-21T05:54:23 < upgrdman> like i feel safe, but i wouldn't tempt someone
2015-09-21T05:54:38 < upgrdman> i bought this place when i was poor
2015-09-21T05:54:38 < kakimir> maybe in cities like inside yaerds of flats
2015-09-21T05:54:42 < upgrdman> so it's in a shit area
2015-09-21T05:54:56 < upgrdman> but im saving up to buy a house in a middle class neighborhood.

2015-09-21T09:10:07 < jpa-> emeb_mac: well, the people who own the buildings have the money, the city who owns the sewers does not or does not care
2015-09-21T09:10:29 < jpa-> it's probably not easy to build your own sewers that go through other peoples land
2015-09-21T09:11:03 < emeb_mac> jpa-: no argument. doesn't make it any less amusing.
2015-09-21T09:11:17 < jpa-> maybe :)
2015-09-21T09:11:39 < emeb_mac> I suppose one should be glad that they're not hand-carrying it out with buckets & shoulder-yokes.
2015-09-21T09:12:11 < jpa-> whereas if they had used dry toilets, it would be so green that it would be cool, no matter how much poopcarrying is involved :)

2015-09-21T09:12:16 < dongs> 480fps video whoa
2015-09-21T09:13:02 < jpa-> collecting sewage by trucks is quite common in the sparsely populated areas in finland
2015-09-21T09:13:42 < jpa-> though they have a system that separates most of the water out of it, so it is mostly sludge that is collected
2015-09-21T09:14:06 < emeb_mac> interesting
2015-09-21T09:14:27 < emeb_mac> so sparsely populated areas don't just use septic tanks?
2015-09-21T09:14:52 < jpa-> some do, but generally it is cheaper to have a filter system so that it doesn't have to be emptied so often
2015-09-21T09:14:56 < jpa-> usually only once a year
2015-09-21T09:15:32 < emeb_mac> hmmm... environmental conditions must be very different there - septic tanks here rarely need pumping.
2015-09-21T09:15:46 < emeb_mac> usually it's an indication that something has gone wrong.
2015-09-21T09:15:47 < jpa-> atleast burj khalifas is more advanced than moscow, where they still just dump the sewage to rivers :)
2015-09-21T09:16:04 < jpa-> emeb_mac: maybe we are thinking about different kinds of septic tanks..
2015-09-21T09:16:39 < emeb_mac> perhaps.
2015-09-21T09:17:00 < jpa-> emeb_mac: where do the solids go in the septic tank that doesn't need to be pumped?

2015-09-21T09:18:46 < emeb_mac> jpa-:  they build up over time - pumping is required at intervals, generally 5-10yrs
2015-09-21T09:18:58 < jpa-> wikipedia's "septic tank" matches pretty much what i called "filter system" above - but some summer houses etc. just choose to put everything into tank raw and have it pumped more often
2015-09-21T09:19:15 < emeb_mac> ah
2015-09-21T09:19:26 < emeb_mac> those are rare here
2015-09-21T09:19:26 < jpa-> hm, has to be a pretty large tank if it can take 10 years of household solids

2015-09-21T09:20:24 < jpa-> but wikipedia seems to agree that they can be pumped quite rarely
2015-09-21T09:20:28 < emeb_mac> much of what counts as solids is able to decompose further
2015-09-21T09:20:45 < emeb_mac> the microbiota in the tank is very important

2015-09-21T09:24:28 < jpa-> seems like the systems here in finland do not take much advantage of decomposing the solids - most of the solids are separated as first step in the process and microbiological processes happen later only to clean the water further
2015-09-21T09:24:56 < jpa-> and it is the first step container that needs to be emptied yearly

2015-09-21T09:26:30 < jpa-> i wonder if that is related to temperature or something.. decomposing might not work very well in here at winter time, it barely stays above 0 at the depth where they are usually buried
2015-09-21T09:26:52 < emeb_mac> good point
2015-09-21T09:30:16 < emeb_mac> there are parts of this city that were only recently annexed and the houses in those areas still aren't on the city sewer and water systems.

2015-09-21T09:31:08 < emeb_mac> so the city is trying to force the people to hook up & remove the septic tanks at great expense. not surprisingly they are resisting.
2015-09-21T09:31:43 < jpa-> yeah, similar here; the nationwide requirements for wastewater processing where made more strict and a lot of people are facing expensive upgrades

2015-09-21T09:34:06 < ds2> oh that city is surrounded
2015-09-21T09:34:21 < emeb_mac> not at all
2015-09-21T09:34:26 < emeb_mac> Tempe is surrounded
2015-09-21T09:34:41 < ds2> isn't Chandler to the south and gilbert to the east?
2015-09-21T09:34:45 < emeb_mac> Mesa has plenty of borders that are still open
2015-09-21T09:35:01 < emeb_mac> to the north, and also to the east of Gilbert
2015-09-21T09:35:25 < ds2> mesa must be bigger then what i am picturing

2015-09-21T17:10:34 < Roklobotomy> i have seen an appnote for the avr showing how to use aes to encrypt firmware.  mebbe they use something like it?
2015-09-21T17:10:43 < dongs> aes would be noise
2015-09-21T17:10:46 < dongs> and wouldnt compress 50%.
2015-09-21T17:10:49 < Roklobotomy> true
2015-09-21T17:11:11 < dongs> my guess is this is xor'd wiht some constant

2015-09-21T17:15:04 < englishman> rot13 is encryption
2015-09-21T17:17:50 < jpa-> lora has funny encryption.. they use aes_encrypt() on uplink, and aes_decrypt() on downlink - so that the end device only needs to support aes_encrypt()

2015-09-21T19:14:03 < dongs> This is especially useful if a menu contains extremely common commands that a user may want to have ready access to at all times, but that some users may not need (so it doesn.t need to be a window all the time).
2015-09-21T19:14:09 < dongs> its called "shortcut key"

2015-09-21T20:20:31 < karlp> no, I never tried the vendor code directly.

2015-09-21T20:22:05 < karlp> Needed a sane way of testing that all the things worked
2015-09-21T20:22:47 < karlp> that got "hard" and I got a little bored trying to figure out what this weeks flavour of how the tty layer was meant to be used
2015-09-21T20:23:09 < fenugrec> Well I have a testsuite of sorts - I connect as half-duplex, and test writes/reads, and with a scope I can verify pattern generation (0x55 bytes @ 10.4k and 15kbps, RTS / CTS twiddling, 25ms / 500ms break on TXD)
2015-09-21T20:23:18 < fenugrec> but it's extra hard to automate
2015-09-21T20:23:43 < karlp> yeah, that's just manual testing.

2015-09-21T20:25:18 < fenugrec> (it lives on my desk now... sooo much easier than going to the garage every time)
2015-09-21T20:25:30 < karlp> I'm not interested in loopback at all, as if you try and set parity and it is ignored for instance, loopback wouldn't catch that at all.
2015-09-21T20:25:57 < fenugrec> Well I'm not interested in parity at all p-))
2015-09-21T20:26:09 < karlp> parity was just an example.
2015-09-21T20:26:21 < fenugrec> (Except for a single 7E1 byte that gets transmitted during init)
2015-09-21T20:26:23 < karlp> ifyou try setting rts and it doesn't set any rts features, loopback would still work too.
2015-09-21T20:27:01 < fenugrec> karlp true. The best would almost be an oldschool modem that honours flow ctl, etc
2015-09-21T20:27:20 < karlp> just needs testtools that can be given a "left" and "right" device
2015-09-21T20:27:25 < fenugrec> but you won't make me believe that all the other serial drivers in the kernel are tested to such an extent
2015-09-21T20:27:38 < karlp> only serial port testing stuff I found was for loopback single device, mostly caring about speed
2015-09-21T20:27:52 < karlp> yeah, they're mostly just tested by lots of users with eweird edge cases
2015-09-21T20:27:58 < fenugrec> hah, simpler even : null-modem two serial ports on the same comp; one "known-good" (or known-better)
2015-09-21T20:28:05 < karlp> hence what I mean about being sad at the state of comprehensive serial port test suites
2015-09-21T20:28:14 < karlp> yeah, that's the way I wanted it.

2015-09-21T20:42:32 < karlp> but I never understood the way the drivers are _meant_ to be called, and "use the source luke" with the entire kernel tree wasns't super helpful.
2015-09-21T20:43:59 < fenugrec> oh yeah I know what you mean. And existing serial driver seems to be architected in a different way

2015-09-22T03:27:26 < dongs> beyond garbage
2015-09-22T03:27:31 < dongs> Wissel, many thanks for the video. If that was your first time flying a drone and controlling it in windy conditions with just your phone/tablet to boot and no GPS then I think that was pretty impressive and those muttering criticisms are being somewhat harsh..
2015-09-22T03:27:32 < Lux> doesn't even look like they tuned the pids properly

2015-09-22T03:28:29 < GargantuaSauce> you pay $60 to china for one with better performance on ALL FRONTS
2015-09-22T03:28:30 < Lux> it's not that hard either
2015-09-22T03:28:42 < Roklobsta> i bet not one of those numpty programmers even sat through a single control system lecture
2015-09-22T03:28:49 < Roklobsta> WIKI PID.  Done.
2015-09-22T03:29:21 < Lux> to be fair it's not like those lectures are that useful
2015-09-22T03:29:48 < Sync> well at least you understand what to do
2015-09-22T03:29:49 < GargantuaSauce> brian douglas youtube lectures are pretty decent
2015-09-22T03:30:00 < GargantuaSauce> as an introduction at least
2015-09-22T03:30:26 < Roklobsta> They think a 'root locus' is something deep fried in tempura batter at a hipster Japanese/Eskimo mashup cafe.
2015-09-22T03:30:31 < Sync> although I'm not sure if PID is right for drones
2015-09-22T03:30:47 < Lux> cascaded pids work well
2015-09-22T03:30:51 < GargantuaSauce> for rate control with a person in the loop it's perfect
2015-09-22T03:31:04 < dongs> Roklobsta: but hand-tuned PIC32 ASM
2015-09-22T03:31:05 < Sync> with a right model you should only need PI
2015-09-22T03:31:23 < Sync> or rather P with feed forward
2015-09-22T03:31:30 < Lux> nah
2015-09-22T03:31:58 < Lux> that won't feel good
2015-09-22T03:32:32 < dongs> 3. The quality of the video is appalling, hopefully this will get better but at the minute that's just horrendous!!
2015-09-22T03:32:35 < dongs> lolz
2015-09-22T03:32:48 < GargantuaSauce> its ok, they have a hpc to stabilize your video in post
2015-09-22T03:32:55 < GargantuaSauce> the cloud solves everything
2015-09-22T03:33:15 < Sync> Lux: my motorcontroller does that
2015-09-22T03:33:25 < Sync> we have no D anywhere
2015-09-22T03:33:36 < Sync> and very little PI components
2015-09-22T03:33:40 < Sync> most is P and FF
2015-09-22T03:35:13 < Lux> but a quad is quite a bit different from a motorcontroller
2015-09-22T03:35:43 < Lux> more like controlling a dc motor for position control i guess
2015-09-22T03:36:28 < Sync> bldc servos with FOC
2015-09-22T03:37:13 < Sync> but it basically is the same
2015-09-22T03:37:18 < dongs> Next question: did you run the resulting 13fps file through the HPC first or not?
2015-09-22T03:37:21 < dongs> posted for lulz
2015-09-22T03:37:42 < Sync> as you know how the thing will react
2015-09-22T03:37:45 < Roklobsta> HPC must be using some open sores image processing.
2015-09-22T03:38:06 < Sync> ffmkek like yotube
2015-09-22T03:38:27 < mtbg> they will increase fps by morphing a frame into next one in a few steps
2015-09-22T03:38:58 < Lux> Sync: true, it's not too hard to simulate and mathematically describe the physical model
2015-09-22T03:39:25 < Lux> but i haven't done that, my experience is more from coding stuff and trying it out
2015-09-22T03:39:35 < Sync> we're running a full physical model in my motor controller
2015-09-22T03:39:56 < Sync> so that we can calculate gravity torque offsets
2015-09-22T03:40:03 < Sync> for e.g. roboter arms
2015-09-22T03:40:52 < Roklobsta> Sync: you planning on flying on Jupiter?
2015-09-22T03:41:06 < Lux> that'll get complex on a quad
2015-09-22T03:41:52 < Lux> you'll also need motors where you can actually set the force they apply and all the physical dimensions etc
2015-09-22T03:41:53 < Roklobsta> eh, big nasty simultaneous equation solver in realtime with fixed point maths at 24MHz.  What could possibly go wrong?
2015-09-22T03:41:57 < Lux> sounds like a pita to me
2015-09-22T03:42:12 < Sync> no, but it is important for roboter arms or linear axis if you want to command a pure torque
2015-09-22T03:42:45 < Lux> heavy industrial roboter arms ?
2015-09-22T03:44:56 < Sync> doesn't really matter
2015-09-22T03:45:15 < Lux> sure does
2015-09-22T03:45:24 < Sync> that way we don't need an integral part in the torque control
2015-09-22T03:45:31 < Sync> nah, the values are just differen
2015-09-22T03:45:32 < Sync> t
2015-09-22T03:45:54 < GargantuaSauce> those usually just use position control i think
2015-09-22T03:46:07 < GargantuaSauce> the fancy newer ones with compliance and stuff have force control

2015-09-22T11:05:33 < jpa-> PeterM: then i fail to see what relevance your ranting has - i haven't seen much disconnections due to any failure in ircclouds connections

2015-09-22T11:14:39 < dongs> I'm really looking forward to the proper app with more of the functions working. This will be great for a newb like me. But what I'm really looking forward to is version 1.1 as I think this is when Zano will really start to shine.

2015-09-22T11:16:58 < icee> dongs: you make me want to find and help the zano guys just for how incredulous you'll be if they actually ship
2015-09-22T11:18:24 < dongs> icee, hte only "help" they need is to throw away everythign tehy have and actually do a proper design
2015-09-22T11:21:32 < PaulFertser> jpa-: also, in gdb "start" and "run" work to reset if extended-remote is used.

2015-09-22T11:22:49 < PaulFertser> Of course, "reset_config srst_only" should be used to actually pull the SRST line down.
2015-09-22T11:24:52 < icee> dongs: yah, but that's the only help anyone ever needs :P
2015-09-22T11:25:02 < ReadError> i searched youtube for zano + past week
2015-09-22T11:25:07 < ReadError> no flying vids ;(
2015-09-22T11:27:27 < emeryth> realistically, what's the highest possible baudrate for a uart on f4?
2015-09-22T11:28:16 < Sync> I have run it at full tilt
2015-09-22T11:29:24 < emeryth> that is?
2015-09-22T11:30:32 < icee> i think some of the usarts you can run at ~3.5MHz
2015-09-22T11:32:55 < Sync> look in the datasheet
2015-09-22T11:36:58 < jpa-> yeah, depends on which uart and which clock speed and whether you need to match some standard rate
2015-09-22T11:37:05 < simoneferrini> And what about the user-defined commands in the console? I'm trying to add a command like "rst" which does "monitor reset halt" as a shortcut
2015-09-22T11:37:33 < simoneferrini> Seems I misunderstood the "define" command
2015-09-22T11:37:56 < PaulFertser> simoneferrini: duh, just use "run" or "start".
2015-09-22T11:38:10 < jpa-> alias rst = monitor reset halt
2015-09-22T11:38:49 < jpa-> but yeah, what PaulFertser says works also, atleast as long as you are debugging the .elf that you are running
2015-09-22T11:39:15 < jpa-> (run/start sets PC to value from .elf i think, not the value from vector table)
2015-09-22T11:39:33 < simoneferrini> jpa-: invalid command to alias to:monitor reset halt
2015-09-22T11:39:33 < jpa-> (or maybe what i remember doesn't apply to extended remote)
2015-09-22T11:40:01 < jpa-> simoneferrini: ah, too bad
2015-09-22T11:40:19 < jpa-> just use define then
2015-09-22T11:40:26 < jpa-> or "run" :P
2015-09-22T11:40:33 < jpa-> or, "r" for short
2015-09-22T11:41:06 < PaulFertser> jpa-: (setting PC) can't confirm or deny, but should be trivial to discover with "set debug remote 1".
2015-09-22T11:41:53 < simoneferrini> The "remote" target does not support "run" :(
2015-09-22T11:42:04 < simoneferrini> Neither "start"
2015-09-22T11:42:33 < PaulFertser> simoneferrini: ``in gdb "start" and "run" work to reset if extended-remote is used. ''
2015-09-22T11:42:47 < PaulFertser> simoneferrini: just do not use remote.

2015-09-22T13:27:18 < qyx_> huh, are they serious?
2015-09-22T13:27:30 < jpa-> why not?
2015-09-22T13:28:31 < jpa-> if they already have the towers, adding the gateways is not that much per tower and range is some 10km
2015-09-22T13:28:36 < qyx_> are they going to shit over the whole ism band with that chirp spread spectrum no-one-knows-how proprietary thing?
2015-09-22T13:29:08 < qyx_> besides that there is only one manufacturer of that stuff and it is not standardised iirc
2015-09-22T13:29:10 < jpa-> over the 868 band within the limits specified, sure
2015-09-22T13:29:37 < kakimir> I wonder if I should get mobira cityman or whatever that was and then hack it with radio firmware
2015-09-22T13:29:50 < kakimir> that thing you carry around
2015-09-22T13:30:00 < jpa-> kakimir: eh, why?
2015-09-22T13:30:06 < kakimir> friend had one
2015-09-22T13:30:33 < kakimir> as radio for ~450mhz area
2015-09-22T13:30:54 < kakimir> there is firmware available for it
2015-09-22T13:31:12 < kakimir> he had a pile of those phones
2015-09-22T13:31:16 < jpa-> qyx_: dunno how standard you consider this, but spec is available  https://www.lora-alliance.org/kbdetail/Contenttype/ArticleDet/moduleId/583/Aid/23/PR/PR
2015-09-22T13:31:21 < kakimir> got them free
2015-09-22T13:32:14 < kakimir> but I think I want something smaller and more modern
2015-09-22T13:33:49 < jpa-> to use for what purpose?
2015-09-22T13:35:18 < kakimir> to be radio faggot
2015-09-22T13:35:25 < kakimir> idk.
2015-09-22T13:36:42 < jpa-> for reception, just use rtl sdr
2015-09-22T13:36:56 < jpa-> for transmission, get hackrf
2015-09-22T13:37:28 < kakimir> crappy stuff
2015-09-22T13:37:50 < jpa-> unless your aim is to talk on amateur radio freqs - but it seems to me that 450MHz is not any amateur band in europe
2015-09-22T13:38:17 < kakimir> he used ism area but with half a watt power
2015-09-22T13:38:23 < kakimir> 433 or so
2015-09-22T13:38:28 < Ecco> What's the difference between the B and BL instructions?
2015-09-22T13:38:41 < kakimir> letter L
2015-09-22T13:38:46 < Ecco> :-D
2015-09-22T13:38:53 < Ecco> sure :)
2015-09-22T13:39:09 < jpa-> kakimir: so hm, transmitting what? or just chatting? is that even legal amount of power for that freq?
2015-09-22T13:39:24 < jpa-> Ecco: bl loads the LR so that you can return from sub routine
2015-09-22T13:39:31 < Ecco> oh ok
2015-09-22T13:39:38 < Ecco> so it's jump vs "jump to subroutine"
2015-09-22T13:39:43 < Ecco> got it, thanks
2015-09-22T13:39:55 < Ecco> ok, GDB is driving me crazy
2015-09-22T13:40:06 < Ecco> when I "step", it actually does "next"
2015-09-22T13:40:14 < jpa-> use "stepi"
2015-09-22T13:40:18 < jpa-> and "display /i $pc"
2015-09-22T13:40:21 < Ecco> ok
2015-09-22T13:41:18 < Ecco> this does work
2015-09-22T13:41:29 < Ecco> but why doesn't it work the "normal" way
2015-09-22T13:41:49 < jpa-> probably compiler optimizations confuse gdb
2015-09-22T13:41:53 < Ecco> hmm
2015-09-22T13:41:57 < Ecco> I build with -O0
2015-09-22T13:42:01 < jpa-> hm
2015-09-22T13:42:09 < jpa-> then it is just open sores crap ;)
2015-09-22T13:42:16 < Ecco> The line I'm debugging is "Obj a = b +c;"
2015-09-22T13:42:25 < Ecco> (that's C++ with operator overloading, "+" should call a function)
2015-09-22T13:42:30 < Ecco> which it does when I stepi
2015-09-22T13:42:42 < Ecco> unfortunately I'm not fluentin ARM asm
2015-09-22T13:43:04 < Ecco> oh wait
2015-09-22T13:43:07 < Ecco> I'm not doing -O0
2015-09-22T13:43:12 < Ecco> I'm just not specifying any -O flag
2015-09-22T13:44:09 < Ecco> Doesn't change a damn thing :(
2015-09-22T13:44:28 < Ecco> also I wrote my own "abort" function, and when I break on it the backtrace is empty :-/
2015-09-22T13:44:38 < kakimir> jpa-: he is radio amateur. he can do the fuk he wants
2015-09-22T13:44:39 < Ecco> (which makes no sense)
2015-09-22T13:44:52 < jpa-> kakimir: nope, limits apply
2015-09-22T13:45:16 < kakimir> chat and modem
2015-09-22T13:45:41 < jpa-> but yeah, looks like amateurs can transmit quite a bit of power on 433 MHz
2015-09-22T13:52:05 < Ecco> Hmm, I feel like I have an issue with my C++ runtime init
2015-09-22T13:52:14 < Ecco> What should be done prior to running C++ code?
2015-09-22T13:53:23 < Ecco> (iow, just like C code expects you to zero-out bss and copy data to RAM)
2015-09-22T13:53:32 < Lux> You need to fix the startup code
2015-09-22T13:53:38 < Ecco> Yes I guess Id o
2015-09-22T13:53:44 < Ecco> but what should it do?
2015-09-22T13:54:11 < jpa-> Ecco: well, if you need the construction of static objects, you should do that
2015-09-22T13:54:12 < Lux> With cpp you also need to run the constructors of global objects
2015-09-22T13:54:24 < Ecco> Yes. This I've explicitely avoided so far.
2015-09-22T13:54:34 < Ecco> I will need it at some point though, but I'm not using any for now
2015-09-22T13:54:37 < Ecco> Supposedly, though
2015-09-22T13:54:39 < jpa-> other than that, crt0 has been enough for all my c++ needs also
2015-09-22T13:54:47 < Ecco> ok
2015-09-22T13:54:55 < Ecco> I've rolled my own crt0
2015-09-22T13:54:58 < Ecco> It's very simple
2015-09-22T13:55:04 < Ecco> Maybe I missed something there

2015-09-22T14:22:28 < karlp> port 3 on the hub works, going to an onboard ft230x, port2 runs across to another riser pcb, then a A socket,
2015-09-22T14:22:44 < mitrax> Ecco: but besides that does everything work properly?
2015-09-22T14:22:48 < karlp> and plugging in one devices just gives "cannot enable port, maybe the cable is bad?" with a usb memory stick,
2015-09-22T14:22:49 < Ecco> mitrax: apparently
2015-09-22T14:22:56 < karlp> and nothign at all with other usb devices I've tired
2015-09-22T14:23:05 < Cyric> is it better to declar a static method inside the class or to have a function in a normal namespace
2015-09-22T14:23:15 < karlp> I wonder if we've got signal integreity problems on getting out to the external connector
2015-09-22T14:23:20 < karlp> that woudl be teh suck.
2015-09-22T14:23:29 < mitrax> Ecco: sounds like something is being optimizated / inlined then, as jpa said, i doubt it has anything to do with some initialization code missing
2015-09-22T14:23:30 < karlp> I didn't think it was _that_ critical.

2015-09-22T14:27:00 < jpa-> dongs: yeah, if you bother to find an intrinsic for setting stack pointer then it should be portable to other compilers also
2015-09-22T14:27:17 < jpa-> dongs: or just rely on the stack pointer from vector table
2015-09-22T14:29:07 < dongs> jpa, __SETMSP()?

2015-09-22T14:45:12 < jpa-> otherwise sounds like a normal idle state, but should be only through the N kilo-ohm resistors
2015-09-22T14:45:22 < karlp> ah, no, turning up the time base, I do see some traffic when I plug in the device
2015-09-22T14:45:32 < karlp> I think these 67ohm resistors are garbage, going to take them off.
2015-09-22T14:45:36 < karlp> no idea where that figure came from
2015-09-22T14:45:42 < karlp> and the hub says it has series resistors built in

2015-09-22T15:56:54 < karlp> a different usb device just pulls high then up and down a lot as I guess the device tries resetting to try and enumerate, but they don't even get as far as logging anything in dmesg

2015-09-22T15:58:37 < zyp> remember that HS signalling uses a much lower voltage than FS
2015-09-22T15:58:51 < karlp> hrm, didn't know that.
2015-09-22T15:59:02 < karlp> the stick is HS card reader, so maybe that's correct then?
2015-09-22T15:59:04 < zyp> HS uses some current loop mode
2015-09-22T15:59:25 < karlp> the FS device I've tried is just another ft232 dongle, it just sits there resetting and never being recognised

2015-09-22T16:00:08 < Ecco> Before that BL instruction, the backtrace as displayed by GDB is OK
2015-09-22T16:00:16 < zyp> karlp, but anyway, this is the hub being defective on one port?
2015-09-22T16:00:23 < Ecco> and right after that BL, the backtrace is empty and only shows __assert
2015-09-22T16:00:23 < zyp> am I reading that right?
2015-09-22T16:00:44 < karlp> well, hub or our layout, yeah.
2015-09-22T16:00:54 < zyp> oh, a hub you're making

2015-09-22T16:01:30 < karlp> neither HS nor FS devices are recognised on port 2, which is the only external port we've made,
2015-09-22T16:01:43 < karlp> the ft230x on port 3 is permanently attached, and it works just fine.
2015-09-22T16:01:43 < zyp> but the other ports work?
2015-09-22T16:01:51 < zyp> huh
2015-09-22T16:01:55 < karlp> and port 1 is an embedded card reader, also works just fine
2015-09-22T16:02:09 < karlp> and it doesn't help if I have it plugged in at power on either,

2015-09-22T16:06:29 < zyp> yeah
2015-09-22T16:06:52 < zyp> if FS is not detected at all, it sounds kinda like bad connection on d+ line
2015-09-22T16:07:38 < karlp> ok, with the FS device, I see D+ high and being pulled low regularly, by device resets I presume.
2015-09-22T16:07:42 < zyp> does this happen on multiple boards, or can it just be a dry solder joint on this one?
2015-09-22T16:07:43 < karlp> for LS device, same behaviour on D- line
2015-09-22T16:07:56 < karlp> well, happened on the only two we've built up.
2015-09-22T16:08:06 < zyp> on both, ok
2015-09-22T16:08:33 < karlp> this third port runs down from a left riser, across the base pcb and up a right hand riser to the extgernal usb port
2015-09-22T16:08:40 < karlp> the working usb devbice is on the base board
2015-09-22T16:09:00 < karlp> but I don't _reallly_ expect the traces are too long or too mismatched or anything.
2015-09-22T16:09:11 < zyp> nah, not for LS/FS
2015-09-22T16:09:17 < zyp> you could run that over coat hangers
2015-09-22T16:09:26 < karlp> that's what I expected.
2015-09-22T16:09:46 < karlp> hmm, D+ is solid low for the LS device resetting
2015-09-22T16:09:51 < zyp> anyway, where are you measuring? close to the hub chip?
2015-09-22T16:10:09 < karlp> closeish to the hub chip.
2015-09-22T16:10:18 < karlp> where the hubchip lines run down onto th ebase board.

2015-09-22T16:11:21 < karlp> but total length from hub down and across and up is ~60-70mm?
2015-09-22T16:12:07 < karlp> yarh, fs is D- solid low, and D+ toggling as it gets pulled low periodically

2015-09-22T16:18:13 < zyp> were the guy designing that drunk? 100n is fucking power decoupling, not signal conditioning

2015-09-22T16:21:46 < zyp> neat, the chip supports swapping D+/D-
2015-09-22T16:21:46 < karlp> thanks for the the help, much appreciated.
2015-09-22T16:21:55 < zyp> in case you fuck up that
2015-09-22T16:21:55 < karlp> yeah, but you need to drop an eeprom down for that.
2015-09-22T16:22:01 < zyp> (or just don't want to route around)
2015-09-22T16:22:05 < zyp> true
2015-09-22T16:22:24 < karlp> it claims you can program the eeprom from the hub, but I can't find any docs on it
2015-09-22T16:23:13 < karlp> and we had an eeprom on a beta board, but though they claim to release the i2c lines if you hold the hub in reset, it kept holding one of the lines, so I couldn't program the eeprom insitu anyway.
2015-09-22T16:24:04 < karlp> there's some windows software for "configuring" the hub, but I don't have it laid out anywhere for eval with the upstream port on a plug, it's permanently on this board, so can't play with any of those features much.
2015-09-22T16:24:35 < karlp> you can run your own entire firmware there too, and have gpios and shit as well as the hub, but even less support for that in the docs, other than, "rom goes here"
2015-09-22T16:25:12 < zyp> you probably don't want to dick around with 8051 anyway
2015-09-22T16:25:35 < karlp> no fucking way
2015-09-22T16:25:47 < karlp> I bought a hub with a sd card reader, not a usb capable 8051 :)

2015-09-22T17:46:14 < gxti> what the hell is a pre-charge FET
2015-09-22T17:46:15 < dongs> 16x32 display?
2015-09-22T17:47:08 < dongs> huh wat
2015-09-22T17:47:19 < dongs> it doesnt have support for selecting /32 duty stuff
2015-09-22T17:47:21 < dongs> thats still external
2015-09-22T17:47:26 < gxti> The internal pre-charge FET can prevent ghosting of multiplexed LED modules. One cause of this phenomenon is the charging current for parasitic capacitance of the OUTXn through the LED when the supply voltage switches from one common line to the next common line.
2015-09-22T17:47:30 < gxti> waow~~

2015-09-22T17:53:13 < dongs> checking zano crap then sleeping
2015-09-22T17:53:19 < gxti> looks like the idea is you have a counter or shitty mcu somewhere driving the row mux, but because of the ram you can do it faster than you can load actual data in
2015-09-22T17:53:31 < dongs> gxti, right
2015-09-22T17:53:33 < gxti> still don't know what the hell the precharge shit is
2015-09-22T17:53:45 < dongs> you load all rows, then shift out /32 thing
2015-09-22T17:54:11 < dongs> it cant be shitty mcu doing it tho
2015-09-22T17:54:14 < gxti> two banks so you can probably also load stuff in in parallel
2015-09-22T17:54:15 < dongs> you'd need to send it at ~max of 25mhz
2015-09-22T17:54:50 < gxti> anyway it's not like i'm going to use this shit. just curious.
2015-09-22T18:03:10 < dongs> Sorry to do a reality check but The zano can never. NEVER achieve stable footage without a built in gimble. Prove me wrong otherwise. It's a hardware limitation and people should not expect it to work like how the marketing video has lead you to believe. It is constantly fighting against the wind and many other environmental variables.The hpc or whatsoever software stabilisation programs can only do so much. If you watch previous videos of the Zano going through the 
2015-09-22T18:03:57 < dongs> Kind of confusing on the explanation there, but nevertheless, unless there is video evidence of the Zano working as per the marketed video. So far all that is showing are crappy videos that I could get from a Chinese drone right now in the market for $100 tbh. Even Chinese drones now has 1080p as basic!!! So what difference is the zano to current drones? An extra LED panel?
2015-09-22T18:04:02 < dongs> haha
2015-09-22T18:04:18 < Sync> I mean if they had a 4k imager and output 1080p I could imagine *some* stabilization out of the hpc

2015-09-22T21:50:19 -!- trepidacious [~trepidaci@217.155.204.2] has joined ##stm32
2015-09-22T21:50:25 < FAalbers> I have a UART question ...
2015-09-22T21:52:06 < FAalbers> I created a simple program that sets up USART6 on the STMF401RE Nucleo dev board and I just want to send out a serial bid stream of the charachter 'a' just to test it out
2015-09-22T21:53:02 < Ecco> ok
2015-09-22T21:53:11 < Ecco> So QFN with hot air gun = not even funny
2015-09-22T21:53:11 < FAalbers> It lights up a LED through GPIO , then transmits the character through USART , and then turns off the LED to make sure it got through the transmission command
2015-09-22T21:53:25 < FAalbers> Here is a link to the simple code
2015-09-22T21:53:29 < Ecco> I don't remember who advised I get a 858D
2015-09-22T21:53:32 < Ecco> but thanks a lot!
2015-09-22T21:53:39 < FAalbers>  https://github.com/faalbers/STM32_f401re_eclipse_UART/blob/master/src/main.c
2015-09-22T21:53:54 < Ecco> it looks *so much* nicer than when I did it with the iron
2015-09-22T21:54:07 < Ecco> Actually the "magic" part is that the chip can auto-align itself with the pads
2015-09-22T21:54:08 < ReadError> Ecco me ;)
2015-09-22T21:54:12 < ReadError> ya
2015-09-22T21:54:18 < ReadError> surface tension
2015-09-22T21:54:20 < Ecco> indeed
2015-09-22T21:54:21 < ReadError> floats er in to place
2015-09-22T21:54:23 < FAalbers> It turns on the LED, but the transmission command gets stuck. Anyone know what I'm doing wrong ?
2015-09-22T21:54:33 < Ecco> which was the biggest source of "uglyness" with the iron
2015-09-22T21:54:43 < ReadError> FAalbers ya you are using that horrible timecube code
2015-09-22T21:54:57 < Ecco> I followed that tutorial : https://www.youtube.com/watch?v=c_Qt5CtUlqY
2015-09-22T21:54:58 < FAalbers> ReadError, Heeey ! You here to
2015-09-22T21:55:17 < FAalbers> ReadError, Wel, that's supposed to be the one to be used no ?
2015-09-22T21:56:22 < Ecco> FAalbers: I don't know how much time you want to put into this
2015-09-22T21:56:40 < Ecco> but you really should consider reading the whole datasheet of your chip
2015-09-22T21:56:41 < FAalbers> Ecco, Enough to get it to work I guess
2015-09-22T21:56:43 < Ecco> yes, it's a long read
2015-09-22T21:57:01 < ReadError> or use chibios and do it in a few lines ;)
2015-09-22T21:57:04 < Ecco> but it's worth every minute
2015-09-22T21:57:10 < Ecco> ReadError: You recommend chibios?
2015-09-22T21:57:45 < FAalbers> Ecco , I did read the datasheet and checked what to turn on and set , but somehow I guess I'm missing something
2015-09-22T21:58:53 < FAalbers> Ecco, I was just hoping USART was common enough for someone to go find the problem right away in my code :)
2015-09-22T21:59:57 < FAalbers> Will have another readup through the HAL Drivers documentation and Datasheet
2015-09-22T22:00:21 < ReadError> Ecco, ya i like chibios

2015-09-22T22:07:45 < Ecco> ok
2015-09-22T22:30:06 < Ecco> Question: is there a way to detect when there's a stack overflow?
2015-09-22T22:32:14 < Tectu> it crashes :)
2015-09-22T22:32:34 < Tectu> make the stacks too big to develop, when it comes to production decrease the size until it crashes. then add a bit of margin
2015-09-22T22:32:45 < Ecco> hmm
2015-09-22T22:32:49 < Ecco> ok, that's one way to do it
2015-09-22T22:33:04 < Tectu> Ecco, ChibiOS/RT also allows you to initialize the stack with a known patter (afaik 0xAA or 0x55). Then there is a scrip that reads out the memory via GDB and tells you how much stack you are using
2015-09-22T22:33:19 < Tectu> Ecco, because obviously the used area will not be continious 0x55/0xAA where the unused area will be
2015-09-22T22:33:27 < Ecco> thing is, the stack grows down, depending on my memory layout it may first overwrite some heap
2015-09-22T22:33:33 < Tectu> Ecco, afaik ChibiOS/RT has an official guide on that
2015-09-22T22:33:37 < Ecco> ok
2015-09-22T22:33:41 < Ecco> I'm not using ChibiOS btw
2015-09-22T22:33:47 < Tectu> ah, sorry.
2015-09-22T22:33:54 < Ecco> interesting read nontheless
2015-09-22T22:36:01 -!- imbearr [~max@193.106.43.227] has joined ##stm32
2015-09-22T22:38:58 < qyx_> Ecco: there is a gcc warning option -Wstack-usage=n which generates a warning if your function computed stack usage is higher than n bytes
2015-09-22T22:39:13 < qyx_> also as Tectu says, your rtos may support stack watermarking
2015-09-22T22:39:18 < qyx_> freertos does that too
2015-09-22T22:39:47 < qyx_> you can even enable runtime checking and theres also API which enables you to retrieve current thread stack usage
2015-09-22T22:40:15 < Ecco> I'm not using any RTOS
2015-09-22T22:40:24 < Ecco> but I'm curious about how it could be done
2015-09-22T22:40:29 < Ecco> at runtime, especially
2015-09-22T22:40:52 < Ecco> also, what happens if I try to access a "reserved" memory area?
2015-09-22T22:41:10 < qyx_> nothing if it is valid
2015-09-22T22:41:12 < Ecco> Because since the SRAM is surrounded by such areas, I could stick the stack on one end
2015-09-22T22:41:15 < Ecco> crap
2015-09-22T22:41:27 < Tectu> you kind of use a linkerscript for that
2015-09-22T22:41:32 < Tectu> to define where your memory starts and where it ends
2015-09-22T22:41:40 < Ecco> Yes I know. This I have written :)
2015-09-22T22:42:05 < Ecco> but I thought some kind of exception would happen if I tried to access a "reserved" memory area
2015-09-22T22:42:07 < qyx_> you could catch bus errors and handle them
2015-09-22T22:42:32 < Ecco> or just crash
2015-09-22T22:42:36 < qyx_> *hard faults
2015-09-22T22:42:43 < Ecco> which would already be better than overwriting memory and crashing later
2015-09-22T22:42:51 < Ecco> but I thought you said nothing would happen, qyx_

2015-09-22T22:43:22 < qyx_> nothing if that accessed memory area is valid
2015-09-22T22:43:37 < Ecco> what do you mean by valid then?
2015-09-22T22:43:43 < Ecco> I mean, given this mapping :
2015-09-22T22:44:05 < Ecco> http://i.imgur.com/rIgOtfS.png
2015-09-22T22:44:23 < qyx_> you can get stack overflow without triggering any exception
2015-09-22T22:44:24 < Ecco> what if I access 0x1FFF CFFF
2015-09-22T22:44:30 < qyx_> and overwrite other parts of your sram
2015-09-22T22:44:35 < qyx_> (outside of your stack)
2015-09-22T22:44:44 < Ecco> yes, of course, if the stack is positionned "in the middle" of SRAM
2015-09-22T22:44:56 < Ecco> but what if I carefully put it right by a "reserved" area?
2015-09-22T22:45:23 < Ecco> (also, this seems like a very simple idea : if it works, why isn't everyone doing this?
2015-09-22T22:45:57 < qyx_> you can overflow your stack in a variety of ways and in bith directions

2015-09-22T22:47:13 < qyx_> the other direction is not actually a stack overflow
2015-09-22T22:47:40 < qyx_> so i am telling a half bullshit now

2015-09-22T22:55:33 < Ecco> so how comes this technique isn't more widely applied?
2015-09-22T22:55:44 < Ecco> (glueing the stack to a "reserved" region)
2015-09-22T22:58:02 < qyx_> it is, you can use MPU for that
2015-09-22T22:58:03 < Sync> goddamn japanese companies
2015-09-22T22:58:18 < Ecco> Oh indeed

2015-09-22T23:13:29 < mtbg> core features are in separate document
2015-09-22T23:13:32 < Ecco> oh ok
2015-09-22T23:13:38 < Ecco> I thought it was STM-specific
2015-09-22T23:13:45 < Ecco> it's actually a cortex-m thing, ok :)
2015-09-22T23:14:03 < mtbg> but it still wont give you full protection
2015-09-22T23:14:15 < Ecco> ok
2015-09-22T23:14:17 < Ecco> I guess
2015-09-22T23:15:17 < mtbg> defining variables on stack can shift sp without trying to write to that locations (i.e. you can skip your canary)
2015-09-22T23:15:34 < Ecco> indeed
2015-09-22T23:16:01 < Ecco> by canary you mean the area that is "reserved" and which I would make trigger an exception?
2015-09-22T23:16:10 < Ecco> (thanks to the MPU)
2015-09-22T23:16:33 < mtbg> yep
2015-09-22T23:16:36 < Ecco> ok
2015-09-22T23:16:41 < Ecco> but if I make it large enough
2015-09-22T23:16:46 < Ecco> Then the risk should be small
2015-09-22T23:17:00 < Ecco> Note that this whole thing doesn't make bad code run
2015-09-22T23:17:01 < mtbg> then probably you are wasting your memory
2015-09-22T23:17:13 < Ecco> My aim here is to catch error when they happen
2015-09-22T23:17:34 < Ecco> Why would I waste memory
2015-09-22T23:17:39 < Ecco> for example, on STM32F401
2015-09-22T23:17:45 < Ecco> SRAM starts at 0x2000000
2015-09-22T23:17:49 < Ecco> Since stack grows down
2015-09-22T23:17:56 < Ecco> I could reserve the first 4KB to stack
2015-09-22T23:18:05 < Ecco> and mark everything below 0x200000 to trigger an exception
2015-09-22T23:18:21 < mtbg> ok
2015-09-22T23:18:23 < Ecco> below that, there is a "reserved" area, then "option bytes" which I don't need just yet
2015-09-22T23:18:29 < Ecco> then again reserved
2015-09-22T23:18:34 < Ecco> and eventually system memory
2015-09-22T23:18:43 < Ecco> (I'm not sure I'm even accessing it at all
2015-09-22T23:18:45 < mtbg> you can do that
2015-09-22T23:18:53 < Ecco> so that would be quite a large area actually
2015-09-22T23:19:01 < Ecco> and I don't see where I "waste" anything
2015-09-22T23:19:04 < Ecco> ok, excellent
2015-09-22T23:19:06 < Ecco> thanks mtbg :)
2015-09-22T23:19:07 < mtbg> then you have fixed maximum stack depth, not sharing the space with heap
2015-09-22T23:19:24 < Ecco> oh I see
2015-09-22T23:19:27 < Ecco> but then
2015-09-22T23:19:34 < Ecco> do people really share memory between stack and heap?
2015-09-22T23:19:41 < Ecco> That would seem awfully complicated
2015-09-22T23:20:11 < Ecco> I see how it could work, but that would require incredible complex engineering
2015-09-22T23:20:19 < Ecco> and would be very hard to maintain
2015-09-22T23:21:42 < mtbg> yep, if you have a way to fail gracefully when you run out of stack or heap, then your solution can make use of it
2015-09-22T23:22:01 < Ecco> Currently, I don't
2015-09-22T23:22:16 < Ecco> but I would much, much prefer a crash
2015-09-22T23:22:22 < Ecco> than stack overwriting heap w/o me knowing

2015-09-22T23:54:22 < Roklobsta> latest i heard is he put a clock guts in a different box and didn't make anything.
2015-09-22T23:54:44 < Roklobsta> reflecting on my own misdirected youth he did it to get a rise out of someone at school and it paid off.
2015-09-22T23:54:58 < Laurenceb__> yeah but microshaft shifted their first unit of stock in years
2015-09-22T23:55:50 < Roklobsta> wait 4 years and hear how he failed 1st semester at caltech or wherever.
2015-09-22T23:56:01 < Roklobsta> because all he can do is swap clock guts.
2015-09-22T23:56:44 < Laurenceb__> lol
2015-09-22T23:57:11 < BrainDamage> he should do sociology / marketing / letters instead

2015-09-23T02:15:07 < FAalbers> karlp, Problem is , I never got an answer. Just RTFM. Which I did ... so I was trying again if someone else connected.
2015-09-23T02:15:47 < FAalbers> If not too bad, I tried
2015-09-23T02:18:24 < karlp> well, the problem with repeating what you're repeating is that anyone new who might help doesn't have any context, they're just seeing a shitty "who knows x" query
2015-09-23T02:18:29 < karlp> which tends to go badly.
2015-09-23T02:18:57 < karlp> you kinda dumped some code and said, "it' don't work" I didn't see any further explanation of what you'd tried further at all

2015-09-23T02:40:51 < FAalbers> karlp, Not true ... This is what I posted
2015-09-23T02:41:12 < FAalbers> I have a UART question ...
2015-09-23T02:41:21 < FAalbers> I created a simple program that sets up USART6 on the STMF401RE Nucleo dev board and I just want to send out a serial bid stream of the charachter 'a' just to test it out
2015-09-23T02:41:31 < FAalbers> It lights up a LED through GPIO , then transmits the character through USART , and then turns off the LED to make sure it got through the transmission command
2015-09-23T02:41:56 < FAalbers> Here is a link to the simple code
2015-09-23T02:42:05 < FAalbers>  https://github.com/faalbers/STM32_f401re_eclipse_UART/blob/master/src/main.c
2015-09-23T02:42:18 < FAalbers> It turns on the LED, but the transmission command gets stuck. Anyone know what I'm doing wrong ?
2015-09-23T02:42:29 < FAalbers> Is that not enough context ?

2015-09-23T02:43:46 < karlp> so...
2015-09-23T02:43:47 < FAalbers> I don't know what else I need to ask to make my problem clear
2015-09-23T02:43:51 < karlp> does it send, and then get stuck?
2015-09-23T02:43:55 < karlp> or does it not get sent at all?
2015-09-23T02:44:11 < karlp> you need to keep digging, looking for edges you can cut off
2015-09-23T02:44:15 < FAalbers> karlp, It gets stuck on that command and it does not send anything
2015-09-23T02:44:54 < karlp> dumping entire programs is normally tedious for other people
2015-09-23T02:45:03 < karlp> first off. check whether you've reallly enabled the clocks you think you have.
2015-09-23T02:45:13 < FAalbers> karlp, Was just hoping someone would see the obvious I'm doing wrong in that small code fragment.
2015-09-23T02:45:14 < karlp> if peripherals don't work, it's always first check
2015-09-23T02:45:25 < karlp> I want you to see it :)
2015-09-23T02:45:42 < FAalbers> It's a very small fragment in main() ... made it as simple as possible
2015-09-23T02:45:59 < karlp> good, nice and small, so look at it closely, and check whether you're enabled the clocks you need.
2015-09-23T02:47:00 < FAalbers> karlp, I use RCC->AHB2ENR |= RCC_APB2ENR_USART6EN;

2015-09-23T02:47:23 < FAalbers> It works with the GPIO clock for the LED
2015-09-23T02:47:45 < karlp> but it doesn't work for the usart maybe?
2015-09-23T02:47:51 < karlp> look closer...
2015-09-23T02:48:25 < FAalbers> karlp, In the datasheet USART6 is under AHB2
2015-09-23T02:48:43 < karlp> are you _sure_ ?
2015-09-23T02:48:48 < karlp> look at that line more closely....
2015-09-23T02:48:59 < FAalbers> karlp, And RCC_APB2ENR_USART6EN exists
2015-09-23T02:49:11 < karlp> and where are you writing that bit numbnuts? how long are you going to take?
2015-09-23T02:49:38 < FAalbers> karlp, to RCC->AHB2ENR
2015-09-23T02:49:46 < karlp> and do you think that's correct?
2015-09-23T02:50:28 < FAalbers> karlp, Wel, that's how it's done for GPIO pin 5
2015-09-23T02:50:41 < FAalbers> RCC->AHB1ENR |= RCC_AHB1ENR_GPIOAEN
2015-09-23T02:50:42 < zyp> spoiler: AHB2 != APB2
2015-09-23T02:50:43 < karlp> you need to _actually_ look at what you're doing.
2015-09-23T02:50:45 < FAalbers> And that works
2015-09-23T02:50:54 < karlp> aw zyp, you're no fun
2015-09-23T02:51:03 < karlp> he had the line and everything, he would have gotten there eventually.
2015-09-23T02:51:12 < karlp> (hopefully)
2015-09-23T02:51:14 < FAalbers> Oh fuck :)
2015-09-23T02:51:22 < zyp> I though you've made him waste enough time already
2015-09-23T02:51:23 < karlp> always check the clocks :)
2015-09-23T02:51:27 < karlp> yeah, I guess.
2015-09-23T02:51:38 < karlp> I didn't actually look at it earlier today, it was stdperiph shitz
2015-09-23T02:51:44 < FAalbers> See it karlp :)
2015-09-23T03:02:39 < FAalbers> karlp, Thanks a bunch ! :) Doesn't get stuck anymore :) Logic Analyzer doesn't detect stream though . Will check first why that is

2015-09-23T06:06:08 < upgrdman> i might etch a PCB to get things nice and close together, but im not sure if i care enough to go through that trouble
2015-09-23T06:07:16 < upgrdman> also, still thinking of how i want to properly drive the high side FET, since i would need to monitor the voltage between source and drain to model a diode
2015-09-23T06:07:51 < upgrdman> no
2015-09-23T06:07:55 < upgrdman> but i'll pass
2015-09-23T06:08:38 < upgrdman> etching at homo is coming to an end for me. i will keep doing little breakouts, but i now have plenty of shit to keep me occupied, so i might as well have china fab me some boards for less than it would cost me to make them
2015-09-23T06:09:02 < upgrdman> and im not poor anymore, so 4L all-the-things

2015-09-23T06:11:44 < upgrdman> and connect all grounds via thin-ish traces?

2015-09-23T06:21:05 < upgrdman> my segway was 9DOF, althrough i never used the 3axis magnetometer
2015-09-23T06:21:41 < upgrdman> i wrote it

2015-09-23T06:22:07 < upgrdman> i gave up when i got to kalman filters
2015-09-23T06:22:24 < upgrdman> but i have since learned a bit of linear algebra so i want to revisit it
2015-09-23T06:22:56 < upgrdman> because at the time it was way over my head, and its a hobby so i do NOT want to just copy someones code to get things working. i want to FULLY understand what im doing.
2015-09-23T06:23:42 < upgrdman> so i just used a crappy PID loop, but i think i made D zero due to noise.
2015-09-23T06:24:18 < upgrdman> and i use my super shit wheel encoders to help when not driving on perfectly level surfaces

2015-09-23T06:30:19 < upgrdman> mostly because most coax helis use two motors
2015-09-23T06:30:37 < upgrdman> so each rotor has slightly different torque, etc.
2015-09-23T06:30:50 < upgrdman> yes they can
2015-09-23T06:30:57 < upgrdman> if they are flying level
2015-09-23T06:31:20 < upgrdman> coax heli dont have that characteristic tilt of normal heli
2015-09-23T06:33:07 < upgrdman> ahahah  http://imgur.com/gallery/qIG7K9X
2015-09-23T06:37:49 < upgrdman> ya
2015-09-23T06:37:53 < upgrdman> nice
2015-09-23T06:38:05 < upgrdman> most rc coax helis are fixed pitch toys.
2015-09-23T06:38:24 < upgrdman> collective pitch ones should be able to do anything the real coax ones can, and more

2015-09-23T07:34:43 < emeb_mac> heh
2015-09-23T07:34:53 < emeb_mac> +1 for the LOL
2015-09-23T07:37:10 < PaulFertser> jpa-: this patch might be related: http://openocd.zylin.com/#/c/2343/
2015-09-23T07:37:51 < ds2> speaking of openocd, how generic is the CMSIS-DAP support?
2015-09-23T07:38:07 < PaulFertser> ds2: what exactly do you mean?
2015-09-23T07:38:08 < jpa-> PaulFertser: nah.. seems to be something else.. it is a nucleo board and shows up as different usb id
2015-09-23T07:38:47 < ds2> PaulFertiser: is that driver generic enough to say, work on an Atmel XplainPro board, LPCXpresso or does one need specific drivers for each variant?
2015-09-23T07:39:10 < PaulFertser> jpa-: it touches error reporting though. I can create an SF ticket later but I'm unlikely do fix it myself, I rarely use stlink.
2015-09-23T07:39:33 < PaulFertser> ds2: generic but only SWD is supported for now.
2015-09-23T07:39:43 < PaulFertser> And no vendor extensions.
2015-09-23T07:39:57 < ds2> PaulFertser: so that means I can flash all those chips?
2015-09-23T07:40:23 < ds2> <--- at the end of the rope with dealing with #@$#!@$!@@!$#!@$# programmers/utilities to flash a damn .hex file
2015-09-23T07:41:08 < PaulFertser> ds2: if the flash in that chip is supported, yes.

2015-09-23T07:49:25 < jpa-> it supports stm32.. and nxp.. and well that's all that i've ever used anyway!

2015-09-23T08:09:11 < upgrdman> ya
2015-09-23T08:09:47 < ds2> the more interesting question is what sort of mount
2015-09-23T08:10:08 < upgrdman> mike shows a few ways
2015-09-23T08:10:30 < upgrdman> i might use his "disk with a hole" style diy mount
2015-09-23T08:10:41 < ds2> there is about 3 3D printed designs
2015-09-23T08:11:02 < upgrdman> ya well i already gave back the 3d printer i was lent
2015-09-23T08:11:14 < ds2> shapeways!
2015-09-23T08:11:19 < upgrdman> fuck that
2015-09-23T08:11:44 < upgrdman> i'd rather buy a laser cutter and make proper shit than pay for some 3d dicked thing
2015-09-23T08:12:02 < ds2> I see
2015-09-23T08:12:22 < ds2> shapeways does an okay job... but then my experience is with metal stuff from them
2015-09-23T08:12:30 < upgrdman> k
2015-09-23T08:13:54 < jpa-> and for laser cutting ponoko works fine

2015-09-23T08:26:29 < upgrdman> anyone know if UML diagrams are useful for C code (no classes) ?
2015-09-23T08:26:47 < upgrdman> like to visualize a state machine, or general control flow
2015-09-23T08:27:34 < jpa-> well, state machines sure, and data structures also
2015-09-23T08:28:43 < jpa-> control flow maybe, though very rarely is an algorithm such that the flow is 1) not apparent from the code and 2) still simple enough to be represented in a graph of reasonable size
2015-09-23T08:31:22 < upgrdman> well for example, firmware. typical scenario is main() configures all of the peripherals, then enters an infinite loop to do some tasks. behind the scenes, ISRs and DMA get stuff done too. would it not be helpful to make a "big picture" type of diagram for this, so someone new to a codebase can more quickly get a feel for things?
2015-09-23T08:32:38 < jpa-> possibly - though i have never seen an useful figure that does that on the control flow level
2015-09-23T08:32:52 < jpa-> more like block diagram level "these are the big modules and they talk with each other"
2015-09-23T08:32:52 < upgrdman> k
2015-09-23T08:33:02 < upgrdman> ya that makes sense
2015-09-23T08:44:05 < jubatus> isn't the point of UML that it is a tool for systems analysis and design
2015-09-23T08:45:05 < jubatus> (therefore it should certainly be useful for high level design before you start bashing out C code)
2015-09-23T08:45:14 < ReadError> i took an entire class on UML
2015-09-23T08:45:25 < jpa-> jubatus: yeah, rarely seen it usefully used
2015-09-23T08:45:26 < ReadError> what a miserable class
2015-09-23T08:45:42 < jpa-> jubatus: it does work fine for documentation after-the-fact, though

2015-09-23T12:23:06 < Roklobsta> i forgot about my electric fence the other day.  both hands on it to lean on the fence.
2015-09-23T12:23:35 < Roklobsta> it's like grabbing a chainsaw i guess
2015-09-23T12:24:12 < PeterM> "huh... its not on..." *moment later* "fuck fuck jesus fuck shit fuck cunt fuck"
2015-09-23T12:24:57 < Roklobsta> something like that.  the spasm that went across my hands, arms and chest were something.
2015-09-23T12:25:18 < PeterM> i know electric fences well
2015-09-23T12:25:29 < Roklobsta> earlier this year i had bare feet and touched it by mistake.  that was worse.
2015-09-23T12:25:52 < Roklobsta> even gumboots don't save you
2015-09-23T12:25:59 < emeryth> Roklobsta: why do you have it in the first place?
2015-09-23T12:26:46 < Roklobsta> i have an acre and 3 goats mow 1/3 of it for me. but an electric fence is needed.  goats are purely driven by eating.
2015-09-23T12:27:08 < PeterM> goats have only little respect for normal fences
2015-09-23T12:27:45 < Roklobsta> damned things can stand on 2 feet for many minutes if they can get at an overhanging branch.  the buggers even eat gum tree bark
2015-09-23T12:27:46 < PeterM> they are quite...ninja like? animals, surprisngly

2015-09-23T13:25:36 < jpa-> do you even have the permit to make three-phase mains installations?
2015-09-23T13:25:54 < jpa-> if you are seeking assistance in burning down the building, there are easier ways
2015-09-23T13:26:44 < jpa-> but mp is probably "motor protector"
2015-09-23T13:26:57 < jpa-> i.e. a fancy kind of fuse
2015-09-23T13:27:16 < artag> i thouhgt that, but don't they usually span all 3 phases ?
2015-09-23T13:27:55 < jpa-> seems that it is present only on the single phase charts

2015-09-23T13:29:00 < artag> i think it's a centrifugal switch for the start capacitor
2015-09-23T13:30:22 < artag> or maybe in the weird world of electricals where contacts are drawn as capacitors, its actually the capacitor and the object near Z1/U2 is the switch
2015-09-23T13:30:30 < jpa-> hm yeah, or could be a combination device.. does that try to say it is internal to the motor, because seems input is on the bottom
2015-09-23T13:31:04 < artag> maybe it's even a PTC, guess that could be used as a start/run switch
2015-09-23T13:31:49 < jpa-> hm, not being in series with the L, i guess a switch for the starter cap makes more sense
2015-09-23T13:32:37 < jpa-> unless the "L" marked there is just a screw terminal and actual motor is on U2
2015-09-23T13:33:16 < artag> motor diagrams tend not to show windings, they're just from the point of view of conneting things to the terminals
2015-09-23T13:34:00 < jpa-> yeah
2015-09-23T13:34:10 < jpa-> i just wonder what the U1 and U2 actually are
2015-09-23T13:34:28 < jpa-> because three-phase case doe not have a terminal called "L" at all
2015-09-23T13:35:17 < artag> 3-phase has L1 L2 L3 and no neutral
2015-09-23T13:35:21 < artag> delta connection
2015-09-23T13:35:49 < jpa-> i guess the layout of the 6 terminals stays the same.. so it is called "U1" in three-phase diagrams
2015-09-23T13:36:00 < artag> U V W are usually the markings for the winding terminals
2015-09-23T13:36:25 < artag> usually/often
2015-09-23T13:36:49 < karlp> U1 U2 for voltages?

2015-09-23T15:11:34 < artag> where are you located ? There are mostly less strict laws in the UK on 3-phase because industrial places usually have proper staff and the laws are to protect domestic users from cowboy fitters

2015-09-23T15:49:10 < dongs> Idea is to double flight time by transporting a second battery.
2015-09-23T15:49:10 < dongs> To switch if first gets empty to second via electrical circuit is not such a big challenge.

2015-09-23T15:50:09 < jpa-> well, both of those would be permit-requiring installations here
2015-09-23T15:50:35 < zyp> I think there are single phase 32A CEE connectors
2015-09-23T15:51:13 < karlp> our single phase measurement devices go to 32amp, but customers want them to go to higher, we have a newer one to 63A now.

2015-09-23T15:54:19 < zyp> then again, norway is weird that most of the country is IT rather than TN
2015-09-23T15:54:26 < zyp> i.e. delta vs wye

2015-09-23T15:55:27 < zyp> this means electric cars can't charge from a 3-phase IT outlet, because they are all wired for wye

2015-09-23T16:35:06 < dongs> but you drop it of at post office.
2015-09-23T16:43:04 < dongs> As for the video quality mentioned above: we haven't even seen video quality from the SDcard yet. That part was not even part of the original campaign. The idea of the original campaign was to stream the video in full quality to the phone with no storage on Zano and that's that. When the idea of the onboard storage got implemented and other additions like swarming came onboard, CPU time was conserved in not streaming at full FPS, but store the video in full frame rat

2015-09-24T03:54:02 < dongs> my CX-10C shipped
2015-09-24T03:54:09 < dongs> by freeairmale so probly a week or two
2015-09-24T04:03:18 < dongs> Are you going to wait for them to tell you that the features are complete before you deem that they've not delivered features that were promised? Until such time that they tell you they have stopped development of, or do not plan to add specific features then they have not failed to deliver promised features... they are just still under development.

2015-09-24T04:16:51 < upgrdman> dongs, neat
2015-09-24T04:17:05 < dongs> they're pretty pro
2015-09-24T04:17:07 < dongs> sharp as fuck
2015-09-24T04:17:21 < dongs> which was the point mostly, i had t hese original fluke leads
2015-09-24T04:17:29 < dongs> that were like 1mm ^2 dullpoint
2015-09-24T04:17:34 < dongs> it was kinda hard to poke into anything small
2015-09-24T04:17:41 < upgrdman> ya hate those
2015-09-24T04:25:14 < dongs> Sense and avoid obstacles with ZANO.s revolutionary 5-axis infrared obstacle avoidance system.
2015-09-24T04:29:53 < upgrdman> so that should obviously be 5DOF. but i forget... what's the diff between an axis and a degree of freedom?
2015-09-24T04:31:32 < dongs> doesnt matter
2015-09-24T04:31:38 < dongs> it doesnt even work
2015-09-24T04:31:44 < dongs> the guy flying it crashed it right into a fucking rock
2015-09-24T04:31:45 < dongs> on first flight
2015-09-24T04:31:48 < upgrdman> lol.
2015-09-24T04:31:49 < dongs> so much for avoidance
2015-09-24T04:31:57 < upgrdman> but seriously, im curious. diff between the two
2015-09-24T04:32:34 < dongs> one is not revolutionary
2015-09-24T04:33:28 < dongs> Having different colored PCB's is definatly an problem, but it just shows how much they went into weight saving.
2015-09-24T04:33:31 < dongs> wat
2015-09-24T04:33:32 < dongs> > different color pcb
2015-09-24T04:33:34 < dongs> > weight saving
2015-09-24T04:33:44 < upgrdman> dat pigment is heavy bro
2015-09-24T04:33:45 < dongs> surely if they wanted to save weight they'd just leave mask fof completely

2015-09-24T15:38:44 < Bundestrojaner> After uint8_t dat=USART2->RDR; in my irq-handler, dat always contains 254 or 255. i've tried PA3 and PA15...
2015-09-24T15:38:44 < Bundestrojaner> here's my config: http://paste.ubuntu.com/12541530/
2015-09-24T15:58:33 < Bundestrojaner> i have set it up to echo what i send on tx.
2015-09-24T15:58:33 < Bundestrojaner> when i send 00, i get 00 e0. Anything else tested returns only e0

2015-09-24T16:17:13 < jpa-> Bundestrojaner: maybe your baudrate is wrong? i.e. clock speed not what you expect
2015-09-24T16:18:02 < jpa-> you can try transmitting from the stm32 and see if that has the correct baudrate
2015-09-24T16:18:23 < Bundestrojaner> jpa-: good idea, thx. I'll try that
2015-09-24T16:23:59 < Bundestrojaner> is there a way to "restart" openocd?
2015-09-24T16:24:39 < jpa-> meaning what?
2015-09-24T16:24:45 < Bundestrojaner> after a few debug-sessions in eclipse, i encounter problems. restarting eclipse and reconecting the discovery-board doesn't fix it.
2015-09-24T16:24:51 < Bundestrojaner> after rebooting my pc, it works again
2015-09-24T16:25:02 < jpa-> umm, close openocd and open it again?
2015-09-24T16:25:28 < Bundestrojaner> jpa-: i don't start it, i guess eclipse does it in background

2015-09-24T20:19:11 < karlp> there's stm32studio, which is an st packaged hacked up eclipse,

2015-09-24T23:51:03 < aandrew> that's a really nice idea built on top of a shit ide :-(
2015-09-24T23:53:26 < upgrdman_> i find the more i use eclipse the better i can tolerate it. it still sucks in many areas, but you get a feel for how to quickly work around most of them
2015-09-24T23:53:58 < upgrdman_> but i still prefer something lighter weight for most tasks
2015-09-24T23:55:11 < upgrdman_> at this point my biggest nags with eclipse are that it's ugly and slow to start up.
2015-09-24T23:55:42 < upgrdman_> oh and it still sucks with a high-dpi monitor
2015-09-24T23:57:19 < Bundestrojaner> aandrew, upgrdman_: has one of you tried code::blocks?
2015-09-24T23:57:48 < Bundestrojaner> i like the ide, but i use it only for atmel's 8bit-µcontrollers
2015-09-24T23:57:57 < upgrdman_> i installed it, found it kinda annoying, and removed it
--- Day changed Fri Sep 25 2015
2015-09-25T00:04:35 < mitrax> what i hate with eclipse is how the project files are tied to the filesystem directory structure, iirc you can't simply add individual files you have to map whole sub-folders, maybe there's a way around it but the UI is super convoluted

2015-09-25T00:24:35 < jadew> in neighbouring countries as well
2015-09-25T00:25:02 < jadew> so I wonder if it's a mentality thing or if the media is spewing lies

2015-09-25T00:33:52 < englishman> simple and popular control arm type for front wheels
2015-09-25T00:34:00  * Laurenceb__ googles
2015-09-25T00:34:17 < Sync> I always wondered why audi did not use mcpherson on the b6
2015-09-25T00:34:20 < Laurenceb__> wait wut
2015-09-25T00:34:26 < Laurenceb__> how can that possibly work
2015-09-25T00:34:29 < englishman> coupld reasons
2015-09-25T00:34:31  * Laurenceb__ brain melt
2015-09-25T00:34:32 < englishman> awd
2015-09-25T00:34:38 < englishman> dual wishbone way much better
2015-09-25T00:34:41 < Laurenceb__> https://en.wikipedia.org/wiki/MacPherson_strut#/media/File:Mcpherson_strut.jpg
2015-09-25T00:34:51 < englishman> audi control arms have more engineering in them than vw entire car
2015-09-25T00:35:02 < englishman> whats wrong Laurenceb__
2015-09-25T00:35:12 < Laurenceb__> it looks like it should turn into twisted metal
2015-09-25T00:35:19 < englishman> what kind of car you have
2015-09-25T00:35:20 < Laurenceb__> wheres the second wishbone?
2015-09-25T00:35:27 < englishman> macpherson isnt double wishbone
2015-09-25T00:41:35 < Laurenceb__> non lol
2015-09-25T00:41:35 < Sync> the s3 has the same setup as the golf englishman :P
2015-09-25T00:41:35 < Laurenceb__> need to get myself one
2015-09-25T00:41:35 < Sync> dual wishbone only is more versatile in setting the camber curve, but mcpherson tends to be lighter or cheaper
2015-09-25T00:41:35 < Laurenceb__> oh
2015-09-25T00:41:35 < Laurenceb__> I understand now
2015-09-25T00:41:36 < Laurenceb__> I didnt realise the camber was allowed to be screwed up
2015-09-25T00:41:36 < Sync> it is not allowed to screw up
2015-09-25T00:41:36 < Sync> it is controlled over the suspension travel
2015-09-25T00:41:36 < Sync> incrasing with moar travel

2015-09-25T00:41:36 < kakimir> Sync: I figured it out as I tried to put new arm in
2015-09-25T00:41:37 < kakimir> It's hard to put bolt in when spring is just in line with hole
2015-09-25T00:41:45 < Sync> that's the wrong way to do it
2015-09-25T00:41:51 < Sync> you remove the thing on top
2015-09-25T00:41:57 < Sync> and the whole assembly drops out
2015-09-25T00:42:17 < englishman> yeah a3 is the odd child
2015-09-25T00:42:29 < englishman> Laurenceb__: thats a drawback in macpherson
2015-09-25T00:42:34 < englishman> as spring compresses camber changes
2015-09-25T00:42:40 < englishman> go watch s1e1 of miami vice
2015-09-25T00:42:45 < englishman> where theyre rolling around in the ferrari
2015-09-25T00:42:48 < englishman> you can see the camber change
2015-09-25T00:42:51 < Sync> which is you want
2015-09-25T00:42:52 < englishman> so you know its a replica
2015-09-25T00:43:00 < englishman> actually a jag underneath.
2015-09-25T00:43:07 < kakimir> need to sleep first
2015-09-25T00:43:19 < Sync> even double wishbone suspensions will follow a camber curve
2015-09-25T00:43:28 < kakimir> I hope there is no alignment shiet when it's placed back to it's place
2015-09-25T00:43:36 < Sync> as it gives you MOAR traction
2015-09-25T00:44:26 < englishman> oh also macpherson has bump steer
2015-09-25T00:44:32 < englishman> due to castered struts
2015-09-25T00:44:38 < englishman> depends on car
2015-09-25T00:45:25 < Laurenceb__> cars are so full of hacks
2015-09-25T00:45:37 < Laurenceb__> like some 80s PC
2015-09-25T00:45:37 < Sync> yeah but you can dial bumpsteer out by adjusting the steering arm connection point
2015-09-25T00:45:44 < englishman> yes cars are junk
2015-09-25T00:45:56 < englishman> Laurenceb__: some pr0n http://i.imgur.com/d7F79af.jpg
2015-09-25T00:46:48 < kakimir> Sync: right way to do stuff 1) remove tonne of plastic and panels
2015-09-25T00:47:14 < kakimir> 2) remove engine and transmission
2015-09-25T00:47:15 < Sync> you only need to remove the rain pan
2015-09-25T00:47:28 < kakimir> 3) change light bulb
2015-09-25T00:47:49 < upgrdman_> 4) insert old light bulb into ass

2015-09-25T02:22:02 < jadew> Sync, not sure if this made the news in germany, but it's all over the place in here and it was the main concern even before it hit the news: http://www.dailymail.co.uk/news/article-3240010/Number-refugees-arriving-Europe-soars-85-year-just-one-five-war-torn-Syria.html
2015-09-25T02:22:37 < jadew> this is the primary reason why the migrants are facing such resistence
2015-09-25T02:24:24 < jadew> the thing is that everyone feels sorry for the refugees, but given the stories that were circulating in our country, people panicked
2015-09-25T02:29:12 < jadew> anyway, I hope this horror will end soon and everyone in need of help will get it, there are clearly lots of people in distress among them
2015-09-25T02:45:04 < Bundestrojaner> jadew: "I'm just wondering because the attitude of the germans is being portrayed as welcoming and chill"

2015-09-25T03:55:02 < dongs> The guys here are also very busy putting Zano's through the rig. Hundred and hundreds have been put through, boxed and some have been dispatched. The Android app should also be on the Google Play store before 5pm today. Might even be up there in an hour. Just a bit of testing left to do.
2015-09-25T03:56:49 < dongs> That being said, Torquing is not new in the field. They just never have delivered a product to consumers and at that volume. Either way, my comparison above stands. Even if you don't get all features as promised, the Kickstarter will be considered fulfilled based on the guidelines from Kickstarter.
2015-09-25T04:00:00 < karlp> a friends kickstarter just got funded, pretty sure they'll deliver without any real delay

2015-09-25T04:03:06 < zyp> how can you tell it's pirated?
2015-09-25T04:03:52 < ds2> the nrf51 is a fine chip
2015-09-25T04:04:15 < artag> except for the 51 bit ?
2015-09-25T04:04:19 < zyp> yeah, it's cool
2015-09-25T04:04:27 < zyp> but the peripherals are a bit limited
2015-09-25T04:04:30 < ds2> it is not an 8051
2015-09-25T04:04:33 < ds2> :P
2015-09-25T04:05:03 < jadew> what is CaH?
2015-09-25T04:05:10 < dongs> dongs against humanity
2015-09-25T04:05:14 < zyp> esp. the GPIOTE module
2015-09-25T04:05:33 < ds2> limited depends on how you view it
2015-09-25T04:05:42 < ds2> as a slave radio chip, the peripherals are fine
2015-09-25T04:05:48 < ds2> and the mux really helps with layout
2015-09-25T04:06:32 < zyp> if you only want a slave radio, there's plenty of other choices
2015-09-25T04:06:56 < ds2> you mean the nRF2x or the CC stuff?
2015-09-25T04:07:06 < zyp> I'm talking about it's role as a full single chip solution
2015-09-25T04:07:21 < ds2> what do you expect to do on there?
2015-09-25T04:07:31 < zyp> I want to make a pwm control signal
2015-09-25T04:07:52 < ds2> it does that
2015-09-25T04:08:02 < ds2> did PWM LEDs on it
2015-09-25T04:08:05 < dongs> barely
2015-09-25T04:08:06 < zyp> sure
2015-09-25T04:08:25 < ds2> would have liked to have more pwm channels but that's a different thing
2015-09-25T04:08:32 < zyp> you can hook a timer to GPIOTE in toggle mode
2015-09-25T04:09:14 < dongs> zyp, it says "licensed to altium parnter #1" or osmething in the closeup video
2015-09-25T04:09:28 < dongs> in <title>
2015-09-25T04:09:36 < zyp> but you'll have to rely on it keeping it sync, since you can't hook one event to high and one event to low, you'll have to hook both events to toggle
2015-09-25T04:09:51 < zyp> nrf52 fixes this and adds set/clear tasks to GPIOTE
2015-09-25T04:10:00 < ds2> ah I see what you mean
2015-09-25T04:10:20 < ds2> didn't care too much for LEDs but if you want to do control like the RC crap...
2015-09-25T04:10:43 < zyp> I don't like the fragility of that
2015-09-25T04:14:00 < zyp> oh, and at 0% duty you'll pretty much get the two events firing simultaneously, are they guaranteed to trigger the task twice when they are both pointed at the same task?
2015-09-25T04:15:01 < zyp> if one of the events suddenly get dropped from that then you're at 50% duty at half the frequency
2015-09-25T04:18:39 < zyp> hmm, set/clear tasks doesn't really solve that either, if you had that then you could get a race condition where clear get triggered after set
2015-09-25T04:25:49 < dongs> does IOS broadcast notifications to BT devices or something?
2015-09-25T04:25:58 < dongs> i dont understand how that idicky thing doesnt need an app to go with it

2015-09-25T04:57:09 < Roklobsta> his control loop was overshooting?

2015-09-25T04:57:26 < jadew> upgrdman, if they would be enforced they would behave
2015-09-25T04:57:50 < jadew> on top of that, better education might help avoid that stuff
2015-09-25T04:57:52 < Roklobsta> his step response was pretty good though.

2015-09-25T08:46:38 < dongs> in 1999 on lunix you had to buy one of like 3 supported cards for it to even try working, and never mind dragging windows across desktops etc

2015-09-25T09:30:56 < PaulFertser> sadara: duh man, LDAP is just one part of the AD, not the main part even I'd say. LDAP is just a specialised database one queries to get some info about computers and users belonging to a domain.
2015-09-25T09:31:00 < sadara> LDAP and  Kerberos == standard
2015-09-25T09:31:23 < sadara> LDAP is the database that serves policy
2015-09-25T09:31:46 < sadara> your either talking about policy or auth
2015-09-25T09:31:52 < PaulFertser> sadara: and how do you apply any policy to a GNU/Linux desktop?
2015-09-25T09:32:04 < sadara> PAM
2015-09-25T09:32:29 < sadara> is one example
2015-09-25T09:32:43 < sadara> How do you apply policy to your users iphones?
2015-09-25T09:33:35 < PaulFertser> sadara: what kind of policy is applicable with PAM? Ulimit for cpu time and ram consumption? Well, and disk quota? Compare that to the extensive security policies as available to a windows workstation that's joined to a domain.
2015-09-25T09:33:41 < sadara> KDE has ldap policy
2015-09-25T09:33:50 < sadara> your asking differnet questions
2015-09-25T09:34:17 < sadara> how do you allpy polict to a windows desktop? You can't, you can only apply it via an accout
2015-09-25T09:34:45 < PaulFertser> sadara: please share a link explaining KDE and LDAP policies.
2015-09-25T09:34:46 < sadara> managed desktops are a falicy in windows, short of encrypting the drive and storing the keys in AD
2015-09-25T09:36:05 < PaulFertser> sadara: of course you apply policy via an account, so what? AD provides both auth (via Kerberos, and that's a completely effortless SSO) and policy via LDAP and also phone numbers and emails for the domain users available right there in one's MUA etc etc.
2015-09-25T09:37:35 < sadara> you do understand that AD is essentially a slightly proprietary version of ldap/kerberos
2015-09-25T09:38:37 < sadara> and that you can emulate an AD server with standard openLDAP/MIT kerberos

2015-09-25T09:41:08 < sadara> Your saying that ldap+kerberos !=  AD. AD = a "standard" for use of ldap and kerberos. there is no reason for linux not to use AD (as you don't even have to have a MS AD server)
2015-09-25T09:41:41 < sadara> the same as saying windows can use HTTP/HTML, even though it's not a MS standard
2015-09-25T09:44:20 < PaulFertser> sadara: no, I'm saying that from a system administrator point of view when you need to manage a big corporate network you can just install w2k8 or whatever and get full integration right away. That's SSO for all network resources (printers, file servers, HTTP proxy etc), fine-tuned security policies, remote access to all domain machines etc etc. Of course, you can try to emulate most of this with
2015-09-25T09:44:26 < PaulFertser> a GNU/Linux server. But are you sure you'll manage? And how much extra time would be spent?
2015-09-25T09:45:20 < sadara> I'll agree that policy enforcement of linux desktops sucks
2015-09-25T09:45:38 < sadara> compared to the same on windows desktops
2015-09-25T09:45:58 < sadara> But the flip side of that is you don't really need as much enforcement

2015-09-25T09:48:52 < PaulFertser> sadara: and btw, do you know windows provides ACLs for every file and resource and that you can't possibly emulate that even for files with POSIX ACLs? Also, windows provides the same sophisticated system for auditing access to them.
2015-09-25T09:50:21 < sadara> give an example of an windows ACL feature (real world) that is not possible on linux
2015-09-25T09:51:26 < PaulFertser> sadara: not sure about real world as I'm not a sysadmin. But if you know windows ACLs you know what I'm talking about. It's just several times more sophisticated and powerful.
2015-09-25T09:52:32 < sadara> PaulFertser, not true. I'm not sure where your getting your info from? I do know windows ACLs, and the auditing framework of both windows and linux
2015-09-25T09:52:57 < sadara> as far as "fine grained" windows really has nothing on linux (selinux)

2015-09-25T09:54:39 < sadara> windows can really only control file policies, from an account point of view. linux allows you to control file access policies similar to the windows method, but also security policies for programs, system resorces, io paths, memory, network resorces
2015-09-25T09:55:04 < sadara> No, we are comparing apples to apples
2015-09-25T09:56:14 < sadara> if you want to compare the complete windows security system, you need to compare it to the complete linux security system, that includes apparmor, selinux, and even LXC
2015-09-25T09:56:42 < PaulFertser> sadara: please show me an example of using selinux for enforcing file-level ACLs integrated in a way that makes it easy to use by a sysadmin.

2015-09-25T09:57:22 < dongs> the joke that everyone turns off
2015-09-25T09:57:23 < sadara> ok, so your comparing windows ACLs to only linux ACLs?
2015-09-25T09:57:38 < PaulFertser> sadara: also, how is it easier to manually configure kerberos, ldap, samba etc to play together nice than installing w2k and creating a domain?
2015-09-25T09:57:45 < sadara> dongs, It's enabled by default on almost all linux desktops
2015-09-25T09:57:59 < PaulFertser> sadara: well, I was comparing windows ACLs with POSIX ACLs (not sure what you mean by "linux ACLs".
2015-09-25T09:58:06 < dongs> sadara, since "lunix desktop" doesn't exist, you are probably wrong.
2015-09-25T09:58:42 < sadara> dongs, Is that like a "windows server" (/ desktop that runs server apps)
2015-09-25T09:58:42 < PaulFertser> sadara: you said I should be comparing windows ACLs with SELinux. OK, I can imagine how selinux can be used to do that and much more, but I haven't seen a nice ready-to-use integrated system that provided that facility.

2015-09-25T10:06:07 < PaulFertser> sadara: xattrs allow one to store any additional metadata for the files. xattrs used to store selinux labels etc. But xattrs do not have any meaning per se, just a storage mechanism for other frameworks to use.
2015-09-25T10:06:10 < sadara> I have a simalar view. I think linux has all the underlying tools to make a good enterprise desktop, but lacks the managment
2015-09-25T10:06:30 < PaulFertser> sadara: linux has no tools, it's just a kernel.

2015-09-25T10:07:38 < PaulFertser> sadara: also, there's no windows ntfs acls, there're windows acls and they are used for many different resources (e.g. individual registry keys, shared memory, sockets etc) and ntfs is a filesystem that supports attaching them to filesystem objects.

2015-09-25T10:07:54 < sadara> PaulFertser, Not true
2015-09-25T10:08:26 < PaulFertser> sadara: isn't https://msdn.microsoft.com/en-us/library/aa374872%28VS.85%29.aspx convincing enough?
2015-09-25T10:08:52 < sadara> PaulFertser, there are only ntfs file system ACLs, there is no way of doing file system access controll without the "NTFS ACLs"
2015-09-25T10:09:05 < sadara> can you do AC on a FAT filesystem?
2015-09-25T10:09:33 < PaulFertser> sadara: no, because FAT has no means to store windows acl objects.
2015-09-25T10:09:54 < sadara> what file systems can srote "windows ACLs"?
2015-09-25T10:10:13 < sadara> what file systems can store "Windows ACLs"?
2015-09-25T10:10:47 < PaulFertser> sadara: NTFS is one I know. But that's not the point. The point is that the same security framework, the same ACLs are used for all the resources, not just files.
2015-09-25T10:11:01 < PaulFertser> Storing something on disk is not the only important usecase.
2015-09-25T10:11:29 < sadara> how do I enforce a bw limit on a network port using an ACL?
2015-09-25T10:11:35 < sadara> sorry, Windows ACL?
2015-09-25T10:12:19 < PaulFertser> sadara: I do not think you can do that.
2015-09-25T10:13:30 < sadara> This is one of those discussions that doesn't really have an end
2015-09-25T10:14:37 < PaulFertser> sadara: have you tried managing an AD network and comparing that to managing a network where you have a GNU/Linux server that you use to provide the services? What were the advantages and disadvantages of both?
2015-09-25T10:15:20 < sadara> Windows ADS = ease of use for the general cases, but also a system lack of flecibility
2015-09-25T10:15:35 < sadara> * flexibility
2015-09-25T10:16:21 < sadara> I found that having a single AD server, and then seconday linux servers was the best comprimist (and windows desktops for the most part)
2015-09-25T10:16:35 < PaulFertser> I wonder what flexibility issues did you really face.
2015-09-25T10:17:10 < sadara> for example, distributing file locks
2015-09-25T10:17:29 < sadara> for versioning of datasheets was a pain
2015-09-25T10:18:00 < sadara> We found no suitable way to do that in a multisite environment with windows only

2015-09-25T10:21:18 < PaulFertser> sadara: well, how is versioning possible otherwise? And is SMBv2 not capable of file locks?
2015-09-25T10:21:42 < PaulFertser> Or just use TortoiseGit which costs nothing.
2015-09-25T10:21:48 < sadara> PaulFertser, smbv2 / CIFS can do locks, but you can't disribute them

2015-09-25T10:23:56 < sadara> you have two file systems, mirrored at two different sites. I want to update a file
2015-09-25T10:24:07 < sadara> in windows, how do you do this?
2015-09-25T10:24:13 < PaulFertser> sadara: mirrored how?
2015-09-25T10:24:25 < PaulFertser> And why?
2015-09-25T10:24:26 < sadara> you tell me?
2015-09-25T10:24:45 < PaulFertser> sadara: I mean I do not get the usecase yet.
2015-09-25T10:24:58 < sadara> I have 4TB of documents on each server, that need constant acces by each site
2015-09-25T10:25:09 < PaulFertser> sadara: DFS probably?
2015-09-25T10:25:57 < sadara> using DFS, if a file is edited at site 1 and 2 at the same time, a collision occures
2015-09-25T10:26:33 < sadara> so person 1 edited a file, person 2 edited the same file, and now person 3 has to merge the changes
2015-09-25T10:27:12 < PaulFertser> I'll let windows experts to answer that. dongs?
2015-09-25T10:27:20 < sadara> person 3 needs a complete copy of both files, so all of one file has to be transfered

2015-09-25T10:28:15 < PaulFertser> To me, that sounds like some poorly organised workflow. When it comes to versioning and merging, one needs VCS. Or else you'll end up with some ad-hoc half-assed ghetto solution.

2015-09-25T10:30:09 < sadara> our solution was to readonly files that were opened for writing at another site, just like what would happen if you were in the same site. I don't see that providing expected behaviour is a "getto" solution
2015-09-25T10:30:57 < PaulFertser> Was it truly safe from race conditions?
2015-09-25T10:31:40 < sadara> yes, a file saved at site 1 was readonly until changes were replicated to site 2, and then reopened
2015-09-25T10:32:17 < sadara> this is only 1 of hundreds of examples
2015-09-25T10:32:32 < sadara> using standard posix tools
2015-09-25T10:33:55 < sadara> the changes were replicated over an rsync connection to save bandwidth, and the locking was handled with a couple of 3 line scripts
2015-09-25T10:34:24 < sadara> this is what my point is, the "corner case" was easy to solve in linux
2015-09-25T10:37:05 < PaulFertser> dongs?
2015-09-25T10:39:06 < sadara> this is a know problem with windows DFS since the beginning btw. and micosofts responce has always been "use a third party solution". It also happens with clustered DFS systems at the same site

2015-09-25T13:02:47 < artag> sorry, I meant MS couldn't turn 10 up to 11. And can't outnumber apple by 10->11. all of which seems a bit restrictive for a numbering scheme that lost all sense of reality at about 3.1
2015-09-25T13:03:21 < artag> whereas Apple went from OS 9 to OS X and afaik didn't preclude anything else
2015-09-25T13:05:00 < artag> the idea of 10 being 'the last windows' is such obvious bullshit that I choose to interpret it as 'end of life'
2015-09-25T13:05:23 < artag> which at least has the advantage of mocking them

2015-09-25T15:39:46 < Ecco> Hmm, building my firmware with -Os "breaks" the LCD panel
2015-09-25T15:39:53 < Ecco> (driver via DMA'ed SPI)
2015-09-25T15:40:00 < Ecco> Is there an easy way to debug this?
2015-09-25T15:43:34 < Laurenceb> use of volatile perhaps?
2015-09-25T15:43:41 < Ecco> yeah that's probably the root cause
2015-09-25T15:43:48 < Ecco> But I've lots of code
2015-09-25T15:43:49 < Ecco> I know
2015-09-25T15:43:55 < Ecco> I'm going to build parts of my code with Os
2015-09-25T15:43:58 < Ecco> and parts with O0
2015-09-25T15:44:12 < Ecco> and bissect which file(s) fuck things up when built w/ 0s
2015-09-25T15:44:14 < Ecco> Os
2015-09-25T15:46:24 < Ecco> yay

2015-09-25T15:55:29 < Ecco> weird
2015-09-25T15:55:42 < Ecco> apparently there are *two* files that need to be built with Os for the bug to appear
2015-09-25T15:55:59 < Ecco> if any of them is built without any "-O" option, the LCD panel works just fine
2015-09-25T15:59:57 < karlp> you're probably relying on undefined behaviour somewhere, you'll find it :)
2015-09-25T16:05:01 < Ecco> Hmm
2015-09-25T16:05:06 < Ecco> ok, I have a possible case
2015-09-25T16:05:32 < Ecco> could "for (int i=0;i<1000;i++){}" be removed entierly by the compiler?
2015-09-25T16:07:50 < dongs> yes
2015-09-25T16:07:57 < Ecco> ok
2015-09-25T16:08:07 < dongs> for (volatile int... ) might not be.
2015-09-25T16:08:09 < Ecco> ok
2015-09-25T16:08:38 < Ecco> indeed that fixed it!
2015-09-25T16:08:50 < Ecco> Seems a bit fragile though
2015-09-25T16:10:39 < dongs> why are you using loops to delay
2015-09-25T16:11:49 < Ecco> I know…
2015-09-25T16:12:00 < Ecco> I just haven't taken the time to write a proper usleep() function just yet
2015-09-25T16:13:04 < Ecco> I might as well write one now
2015-09-25T16:13:09 < Ecco> How should I do it?

2015-09-25T16:17:08 < Ecco> ok wait I didn't get it
2015-09-25T16:17:24 < Ecco> so SysTick can generate an interrupt at a given frequency
2015-09-25T16:17:34 < Ecco> what about the cycle counter? How should I use it?

A series of simple tutorials to help first time drone operators start off with the basics and grow in the confidence and ability along with Zano as over time, Zano will get smarter and better as we release software updates.
2015-09-25T17:25:48 < dongs> play store:
2015-09-25T17:25:48 < dongs> GPS, Sonar, infrareds, gyroscopes, accelerometers and barometric air pressure sensors all combine to give ZANO unparalleled flying intelligence. Giving you the freedom to capture fantastic aerial photos and videos without any flight training at all.

We will publish a priority list soon showing what we are working on and expected release dates for each piece of functionality.

2015-09-25T23:35:59 < GargantuaSauce> jeez just a length of dowel
2015-09-25T23:39:02 < upgrdman_> well but i mean the brackets to hold it too. was tempted to bolt some conduit between legs of a workbench, but it would be nice if it was portable instead
2015-09-25T23:39:34 < upgrdman_> like two triangle that hold the shaft, so you can pick it up and move it wherever you need
2015-09-25T23:39:39 < GargantuaSauce> sounds like you should go to the hardware store with a ten dollar bill
2015-09-25T23:39:45 < upgrdman_> lol k

2015-09-26T00:43:35 < Laurenceb__> whats the smallest stm32?
2015-09-26T00:44:30 < Laurenceb__> physical size wise
2015-09-26T00:45:27 < GargantuaSauce> there's that f030 in tssop-20 or something
2015-09-26T00:46:11 < GargantuaSauce> oh there's newer ones in smaller packages
2015-09-26T00:46:16 < aadamson> the bgas are probably the smallest
2015-09-26T00:46:21 < aadamson> 2.1 x 2.1mm
2015-09-26T00:46:27 < Laurenceb__> ah thats nice
2015-09-26T00:46:38 < Laurenceb__> I need < 3.5mm x 3.5mm
2015-09-26T00:46:51 < aadamson> depends on the family/features you want I would presume
2015-09-26T00:47:20 < Laurenceb__> I only need half decent sleep mode and spi with a couple of gpio
2015-09-26T00:47:42 < Laurenceb__> just a really simple spi controlling application
2015-09-26T00:47:46 < aadamson> yeah, probably the F0's then in that bga package
2015-09-26T00:48:02 < Laurenceb__> ok
2015-09-26T00:48:11 < aadamson> or the regular f0's are in 5x5 at 32 pins but that might be larger than you want
2015-09-26T00:48:24 < Laurenceb__> yeah I might just fit 4x4mm
2015-09-26T00:48:28 < Laurenceb__> but prefer smaller
2015-09-26T00:48:31 < aadamson> L0's too probably
2015-09-26T00:48:51 < GargantuaSauce> WLCSP36 2.6x2.7 mm
2015-09-26T00:48:56 < GargantuaSauce> f051
2015-09-26T00:48:57 < aadamson> but they are a RPITA to program as you have to deal with CUBE :)
2015-09-26T00:49:43 < aadamson> there is also a 4x4 QFN (but pin size will increase the size) also in the F0's
2015-09-26T00:50:48 < Laurenceb__> yeah I'd fit QFN if it wasnt for the pads
2015-09-26T00:51:06 < Laurenceb__> I have a pcb that needs to fit flush with a plastic housing
2015-09-26T00:51:13 < Laurenceb__> and the solder will get in the way
2015-09-26T00:51:27 < Laurenceb__> unless i dremel the housing on the whole production run lol
2015-09-26T00:51:53 < aadamson> oh, sorry, I did say QFN, but was thinking QFP... duh
2015-09-26T00:52:00 < aadamson> there is a 4x4 qfn - f038x
2015-09-26T00:52:07 < aadamson> no pins :)
2015-09-26T00:52:38 < GargantuaSauce> it looks like the chipscale ones arent out yet
2015-09-26T00:52:41 < aadamson> 031, 038, 042, 048
2015-09-26T00:53:22 < Laurenceb__> maybe I'll have to use avr

2015-09-26T00:58:49 < aadamson> check octopart if you didn't, but I suspect you are right, st has a bunch of new parts out that aren't avail yet
2015-09-26T00:58:53 < aadamson> might also look at nxp

2015-09-26T01:21:33 < englishman> Laurenceb__: there are like 2.1x2.1mm wlcsp
2015-09-26T01:21:43 < englishman> o already answered :/
2015-09-26T01:22:44 < Laurenceb__> there is like 0 stock :P
2015-09-26T01:23:15  * Laurenceb__ returns to raging at his broken flexipcb
2015-09-26T01:23:39 < Laurenceb__> anyone know anywhere that does flexi with FR4 reinforcement?
2015-09-26T01:23:52 < Laurenceb__> I'm using pcbpool but the reinforcement sucks
2015-09-26T01:25:05 < englishman> im sure theres a bunch of dudes prototyping with wlcsp from digikey thats why thers no stock
2015-09-26T01:25:34 < Laurenceb__> digikey did have some stock?
2015-09-26T01:26:03 < Laurenceb__> I like the slcsp 25 pinout, the internal pins can be left unused

2015-09-26T06:56:15 < upgrdman> ya im trying to use a nmos for high side.
2015-09-26T06:58:07 < PeterM> upgrdman, yeah, you put a zero crossing detector on the end of the output inductor so when the coupled charge stops flowing it turns off before it reverses ( from the output caps back down to ground)
2015-09-26T06:59:20 < upgrdman> how would i made a zero crossing detector? op amp as comparator?
2015-09-26T07:01:03 < PeterM> you could just do a shitty one with series resistor, clamping diode and a fast gpio, and detect at the gpio low threshold
2015-09-26T07:01:28 < PeterM> interrupt even
2015-09-26T07:02:24 < upgrdman> series resistor as high-side current shunt?

2015-09-26T07:07:08 < PeterM> between the inductor and the fet, put like a 100k resistor to an IO, and then on hte IO put a low vf signal diode to clamp it to -0.4v~, and another to clamp it to ~3.7v, when the input is high, the input is high, when it goes negative the inpout is low?
2015-09-26T07:08:30 < upgrdman> hmm ok. i think i understand.

2015-09-26T07:38:08 < upgrdman> PeterM, been thinging about that zero crossing detector. as soon as the high-side fet gets turned on, that 100k resistor will see Vout. so it will zero cross back to zero until the output cap is fully drained.
2015-09-26T07:38:32 < upgrdman> *so it will never cross back to zero
2015-09-26T07:47:38 < PeterM> this is true
2015-09-26T07:47:53 < PeterM> i will ponder some more
2015-09-26T07:48:16 < upgrdman> much appreciated.
2015-09-26T07:48:38 < upgrdman> the only think i can thing of is a current shunt + high side current sense amp... but that seems way overkill.

2015-09-26T07:56:44 < upgrdman> i should redo my segway robot and do it moar better
2015-09-26T07:57:09 < PeterM> i think yo ucould do it bodge and put a diode in parallel to the fet (like you should anyway) and then tunr the fet off before the current drops too much, so when the fet turns off the diode handles it until it drops to 0
2015-09-26T07:57:58 < upgrdman> ya but fuck it. the sepic is no longer fun ;(

2015-09-26T08:03:54 < PeterM> more parts but they keep themselves under cdontrol
2015-09-26T08:04:13 < upgrdman> PeterM, oh ya, that's why the other coil and diode are needed huh?
2015-09-26T08:06:42 < upgrdman> PeterM, iirc forward converters are common in atx psus? they often ground the outputs to mains earth, so why did they pick that topology?
2015-09-26T08:08:11 < PeterM> forward converters are efficient in silicone, in copper and magnetics
2015-09-26T08:08:43 < PeterM> the output is electrically isolated from the input too which is very important

2015-09-26T08:14:09 < PeterM> if you have a non isolated supply and you use a buck topology or something, if the main switch gets stuck closed you get mains voltage on hte output, also, when you rectify the mains, even though the voltage on the filter cap is at 280v or 333v or whatever, that varies in polarity to earth ground depending on what side of the diode bridge is turned on
2015-09-26T08:14:48 < PeterM> that meanas you'd need to then refrence your computers case to the capacitor - not earth ground
2015-09-26T08:15:21 < PeterM> and since the cap is directly connected to the diode bridge, you get mains voltage on your case
2015-09-26T08:16:00 < PeterM> if you use an isolated supply it is always mains earth + 12v or whatever
2015-09-26T08:20:23 < upgrdman> hmm
2015-09-26T08:21:10 < PeterM> its a bit unintuitive compared to how you are taught in school etc
2015-09-26T08:21:39 < upgrdman> my formal training is in comp sci, i just do ee for fun and work :)
2015-09-26T08:22:08 < upgrdman> but ee work stuff is mostly just firmware and test software

2015-09-26T08:23:13 < upgrdman> orly
2015-09-26T08:23:39 < PeterM> the unrectified trace is measured between the transformer windings/mains right
2015-09-26T08:23:41 < Bright> why's it only go to 2 on the rectified output
2015-09-26T08:23:56 < PeterM> but the rectified output is measued between the oputput of the rectifier
2015-09-26T08:23:57 < upgrdman> Bright, chinese diodes?
2015-09-26T08:23:59 < Bright> lol
2015-09-26T08:24:06 < Bright> i use a FET bridge
2015-09-26T08:24:15 < Bright> or i would if i designed products
2015-09-26T08:24:17 < Bright> which i don't...
2015-09-26T08:25:28 < PeterM> since the rectifier is switchging polarity every half cycle you would actually get a offest between one side of the input and the output

2015-09-26T08:43:53 < PeterM> with the bridge rectifier you arent chaging the polarity of the mains, you're just changing the way it connects to your circuit
2015-09-26T08:44:02 < upgrdman> ya
2015-09-26T08:46:10 < PeterM> i think that drawing is wrong sorry

2015-09-26T08:46:35 < PeterM> the B example is qwrong
2015-09-26T08:46:43 < PeterM> ill fix it again
2015-09-26T08:47:12 < PeterM> its equally as bad the outcome though
2015-09-26T08:47:41 < mtbg> B will be dependent on what the load of this bridge is
2015-09-26T08:48:20 < PeterM> n0 b will be completely different

2015-09-26T08:57:35 < mtbg> yep
2015-09-26T08:58:44 < PeterM> so every half cycle, your case is essentially connected to the live of your mains
2015-09-26T09:00:06 < PeterM> but even worse, if you put that cap there, on the other half cycle you get rectified mains minus regulated output voltage on your case
2015-09-26T09:00:31 < PeterM> because the cap level shifts the ground when the other diodes dont conduct
2015-09-26T09:00:40 < PeterM> or someting like that

2015-09-26T09:14:17 < upgrdman> i want to mod these for continuous rotation
2015-09-26T09:14:31 < upgrdman> and some servos use a half-moon output gear so you cant do that
2015-09-26T09:14:53 < upgrdman> others just use a press-in pin to limit travel... which can be removed

2015-09-26T11:24:48 < mtbg> the connection probably is meant to be outside the device and is presented on the schematic just to give an idea about potentials relative to PE
2015-09-26T11:25:00 < mtbg> if you are refering to that PeterM schematic
2015-09-26T11:27:59 < mtbg> any modern installation has RCD which will likely turn off when you connect N with PE anywhere after the breaker if there was enough current in L - N loop
2015-09-26T11:28:21 < kakimir> yes
2015-09-26T11:40:06 < kakimir> 30mA RDC would turn off at ~60mA

2015-09-26T13:01:35 < GargantuaSauce> that is weird
2015-09-26T13:04:54 < GargantuaSauce> it does just seem like an oversight but it's lasted through 10 revisions...

2015-09-26T13:11:57 < GargantuaSauce> crazy right
2015-09-26T13:13:37 < jpa-> there is no gap in binary values, so does there even exist /32 factor?
2015-09-26T13:13:59 < fenugrec> hehe, like they copy-pasted some chapters on the timers and one of them lets you think TIM15/16/17 have a downcounting mode. So you try to use that in your code, only to realize a few hours later that those timers don't have such a mode
2015-09-26T13:14:15 < jpa-> it seems to me that documentation is correct and hardware is weird
2015-09-26T13:15:06 < fenugrec> jpa- I think the only real answer would be to rig a test a measure the actual frequencies... that's a prescale selector, right ?
2015-09-26T13:15:57 < jpa-> well, stm32f4xx.h agrees on there not being a DIV32 factor
2015-09-26T13:18:37 < ReadError> anyone have or seen some decent 5x5 or 10x10cm breakout boards ?

2015-09-26T13:18:54 < decimad> Well, then I'll document it as weird in my sources... the hardware must be more complex because this encoding needs special cases... strange people

2015-09-26T13:19:23 < jpa-> decimad: i think it is a consequence of having the div factor be 2 at the minimum

2015-09-26T13:23:57 < decimad> jpa- which factor do you mean? the ahb prescaler factor can be 1 as well... though I wonder why they didn't encode it as a normal exponent... 0 => 2^0, 1001 => 2^1
2015-09-26T13:24:25 < GargantuaSauce> i'd call it a consequence of 0xxx being no division

2015-09-26T13:25:38 < jpa-> yeah, it makes more sense if you reorder the bits so that it is xxx0 instead of 0xxx
2015-09-26T13:26:01 < GargantuaSauce> > The clocks are divided with the new prescaler factor from 1 to 16 AHB cycles after HPRE write.
2015-09-26T13:26:04 < jpa-> they have just for some reason added AND gate so that other bits are don't-care if the lowest bit (for 2x divider) is 0
2015-09-26T13:26:15 < GargantuaSauce> so it's a weird 2-stage thing
2015-09-26T13:26:28 < GargantuaSauce> where it will only write to the register after the first stage strobes
2015-09-26T13:28:34 < decimad> stage strobe? are you talking vhdl-level stuff?
2015-09-26T13:29:43 < GargantuaSauce> yeah the second bit just enables an extra /4 instead of /2
2015-09-26T13:30:05 < decimad> I can see that a special activated-bit is necessary in order to bypass the dividing counter... otherwise /2 would be the min... but still, with the other bits you'd index the bits in the counter and they artificially added a gap in there

2015-09-26T16:21:35 < ehsanv1> hi, please help me. http://pastebin.com/QmrFqqWe
2015-09-26T16:21:46 < ehsanv1> i have problem in set and get time
2015-09-26T16:21:59 < ehsanv1> specially in daylight saving time
2015-09-26T16:22:02 < dongs> awful indentation and coding style
2015-09-26T16:23:02 < ehsanv1> dongs: me?!
2015-09-26T16:23:07 < dongs> yes
2015-09-26T16:23:12 < ehsanv1> thanks :D
2015-09-26T16:23:45 < dongs> does localtime() return allocated struct tm?
2015-09-26T16:23:47 < ehsanv1> time does not get 1 hour back after 22Sep
2015-09-26T16:24:23 < ehsanv1> dongs: yes, allocated
2015-09-26T16:24:41 < PaulFertser> ehsanv1: if(ti->tm_mon >= 9 && ti->tm_mday > 22) ti->tm_isdst = 1; // dst effect doesn't look ok
2015-09-26T16:25:21 < ehsanv1> PaulFertser: i did it because dst (-1 hour) after 22 sep
2015-09-26T16:25:31 < ehsanv1> PaulFertser: so how can i do that
2015-09-26T16:25:41 < PaulFertser> ehsanv1: think again about logic of your condition.
2015-09-26T16:25:56 < ehsanv1> and beside, user does not set every day. so somehow it should calculate by GetTime
2015-09-26T16:26:06 < dongs> as i said.
2015-09-26T16:26:08 < dongs> the problem with your code
2015-09-26T16:26:12 < dongs> is awful fucking coding style
2015-09-26T16:26:17 < dongs> indent it and you will see the problem
2015-09-26T16:26:29 < PaulFertser> ehsanv1: also, what country is that? I thought DST transition always take place saturday night, not really some specific date.
2015-09-26T16:26:47 < ehsanv1> +3:30
2015-09-26T16:26:49 < ehsanv1> Tehran

2015-09-26T16:27:42 < GargantuaSauce> rolling your own datetime logic is such a losing battle
2015-09-26T16:28:06 < PaulFertser> PeterM: specific hour depends on timezone and country, but yes, it's always on early sunday, not strictly after the 22nd Sep.
2015-09-26T16:28:27 < PaulFertser> GargantuaSauce++ ehsanv1, just use what POSIX features newlib already provides.
2015-09-26T16:28:36 < GargantuaSauce> and certainly not after the 22nd of every month after september
2015-09-26T16:28:57 < ehsanv1> PaulFertser: i'm using IAR, does it have newlib?
2015-09-26T16:29:14 < PaulFertser> ehsanv1: ask dongs how to do it properly with Keil and other proprietary toolchains :)

2015-09-26T16:30:11 < PaulFertser> ehsanv1: anyway, I recommend always keeping UTC in your RTC and convert it to time_t whenever needed. And when you have to present the time to the user, use library functions to account for timezones and such.
2015-09-26T16:30:35 < ehsanv1> PaulFertser: as i dont have touch device, i just rewrite and send hex by email and they call me back and say what happen ! this process really ugly

2015-09-26T17:34:12 < Laurenceb__> I "solved" this problem using FAT32
2015-09-26T17:34:30 < Laurenceb__> it doesnt really have a concept of local versus UTC
2015-09-26T17:34:56 < Laurenceb__> but the files are usually timestamped with an appropriate time :P
2015-09-26T17:35:07 < Laurenceb__> so I use that to set the RTC
2015-09-26T17:36:36 < jpa-> Laurenceb__: you mean, pc saves file to usb, stm32 takes timestamp from that?
2015-09-26T17:36:54 < Laurenceb__> yes
2015-09-26T17:37:08 < Laurenceb__> its a bit goofy to use, but I dont care lol
2015-09-26T17:37:14 < jpa-> yeah, i've thought about that sometimes :P
2015-09-26T17:37:21 < Laurenceb__> there are detailed step by step instructions in the manual
2015-09-26T17:37:29 < jpa-> too bad there isn't standard usb class for "just tell me the time thx"
2015-09-26T17:37:37 < Laurenceb__> also I "factory" trim the RTC to +-1ppm
2015-09-26T17:37:39 < Laurenceb__> yeah
2015-09-26T17:38:17 < Laurenceb__> user has to save a file called time.txt to the device
2015-09-26T17:40:12 < emeb> filename should be 'jihad.txt"
2015-09-26T17:41:04 < Laurenceb__> only really fail part is that I set it to follow UK daylight saving time
2015-09-26T17:41:52 < emeb> contents of "time.txt" file could be offset from UTC

2015-09-26T17:49:34 < jpa-> "supposed to"
2015-09-26T17:49:37 < Sync> by not being dissipative
2015-09-26T17:49:41 < Sync> and charging you up
2015-09-26T17:50:06 < jpa-> yeah, if it was not conductive to ground, fans and similar quite easily charge things up
2015-09-26T17:50:20 < jpa-> and even if you are not supposed to touch it to stuff, you know, things happen
2015-09-26T17:50:29 < Ecco> I see

2015-09-26T18:18:43 < Ecco> So the camera had a different power source
2015-09-26T18:18:56 < dongs> that was teh case until kids started flying
2015-09-26T18:19:12 < dongs> anyway, thats from gopro or similar cam

2015-09-26T18:19:22 < dongs> but for a while even fpv stuff had a separate battery

2015-09-26T18:21:35 < dongs> and it works better cuz if you fly on 3S your 12V cam/vtx don't cut out when voltage drops below 10V or whatever

2015-09-26T20:32:04 < PaulFertser> ReadError: so quad control is more similar to a CP heli than that of an FP heli? News to me.
2015-09-26T20:32:08 < Lux> isn't a quad a lot easier to fly ?
2015-09-26T20:32:21 < ReadError> Lux, ehhh a bit
2015-09-26T20:32:25 < Lux> even in acro mode i'd imagine
2015-09-26T20:32:28 < ReadError> but most FBL helis have similar feel
2015-09-26T20:32:36 < ReadError> since thats the direction helis are going now too
2015-09-26T20:32:50 < Lux> ah ok, so they have gyro stab too
2015-09-26T20:32:52 < ReadError> so some stab
2015-09-26T20:33:13 < ReadError> PaulFertser, yea its pretty much indentical
2015-09-26T20:33:25 < ReadError> in terms of muscle memory and how you fly it around
2015-09-26T20:33:43 < PaulFertser> ReadError: and an FP is different?
2015-09-26T20:33:57 < ReadError> FP is less responsive
2015-09-26T20:35:04 < PaulFertser> I had an impression it's way more different...
2015-09-26T20:35:51 < PaulFertser> That an FP will hover still if I let the stick go, and a CP would continue wandering to where I directed it just before.
2015-09-26T20:35:57 < ReadError> well
2015-09-26T20:36:00 < ReadError> coaxial will
2015-09-26T20:36:13 < PaulFertser> No, not talking about coax here.
2015-09-26T20:36:30 < upgrdman> PaulFertser, fp would help with orientation
2015-09-26T20:36:54 < upgrdman> my first rc heli was fp, and it helped a lot
2015-09-26T20:37:18 < upgrdman> fp also tends to a tolerate crash a little better (but not by much)
2015-09-26T20:38:00 < ReadError> yea, seriously though, look in to a cheap quad

Am I supposed to drill the figures on sim again and again and again for hours then try it live, fail, crash, repair, try it again, order parts, wait (while having quality sim time), repair, finally manage it and then show to some friend and he'll say either "duh" or "I can't understand anything" and then you proceed to the next trick. Is that the way?

2015-09-26T23:35:34 < Laurenceb__> thats a huge stray capacitance
2015-09-26T23:35:47 < aadamson> yeah, that's key figuring out the right *stray* cap...
2015-09-26T23:35:52 < aadamson> or should I say the magic
2015-09-26T23:35:53 < Laurenceb__> there are, iirc its ~1pF or less
2015-09-26T23:36:19 < Laurenceb__> so basically a rounding error when choosing the right cap
2015-09-26T23:36:27 < aadamson> if you read the STM manuals they also reference a very large stray value... somewhere there is an APPnote about it
2015-09-26T23:36:33 < Laurenceb__> as you have to pick a value you can find
2015-09-26T23:36:36 < Laurenceb__> really
2015-09-26T23:37:05 < aadamson> found it - http://www.st.com/web/en/resource/technical/document/application_note/CD00221665.pdf
2015-09-26T23:38:43 < aadamson> FWIW, I typically use 1-3 assuming I can get traces equal length and *next* to the pins or as reasonable as possible given component sizes
2015-09-26T23:41:23 < Laurenceb__> looks complex
2015-09-26T23:41:29 < Laurenceb__> gain margin :S
2015-09-26T23:42:06 < kakimir> 3pF pad capacitance
2015-09-26T23:42:18 < decimad> why is he trying out capacitance values if he could just calculate them to fit perfectly?
2015-09-26T23:42:33 < decimad> in aadamson's link
2015-09-26T23:44:35 < kakimir> and when load capacitance is 6pF
2015-09-26T23:44:41 < kakimir> then cap size is 6pF
2015-09-26T23:44:45 < kakimir> rite?
2015-09-26T23:46:29 < aandrew> yeah those rules of thumb need to be taken with a grain of salt
2015-09-26T23:46:40 < Laurenceb__> hmm
2015-09-26T23:46:46 < Laurenceb__> I think its 2.5pF
2015-09-26T23:46:59 < Laurenceb__> as each pin is typically ~5pF to gnd
2015-09-26T23:47:11 < decimad> That link's calcs would suggest C = Cl +- sqrt(Cl²-Cs)
2015-09-26T23:47:30 < aandrew> they assume 2-layer boards or specific stackups etc
2015-09-26T23:47:46 < aandrew> when you're talking about individual picoFarads you need to actually do the math
2015-09-26T23:48:34 < aandrew> things like differential microstrip and such talk about the 3H rule which is a much better way to look at things becuase they take into account the distance to the reference
2015-09-26T23:49:19 < decimad> It's a miracle our oscillators work at all, right
2015-09-26T23:49:38 < kakimir> I use 6pF and if it works it works
2015-09-26T23:49:58 < decimad> Try and see if 12pF would work too ;)
2015-09-26T23:50:07 < kakimir> and never have another thought about it
2015-09-26T23:50:33 < aandrew> kakimir: if you just need the thing to oscillate that approach works fine
2015-09-26T23:51:02 < aandrew> if you're trying to hit a spec or minimize PVT you need to do some math and measurement
2015-09-26T23:51:15 < decimad> I like oscillations, mostly those vertical ones
2015-09-26T23:52:17 < Laurenceb__> oops I was wrong earlier
2015-09-26T23:53:04 < Laurenceb__> double the specified loading capacitance, then take off ~5pF
2015-09-26T23:55:12 < kakimir> how to measure it
2015-09-26T23:55:51 < kakimir> can I put scope probe there without interference?
2015-09-26T23:56:00 < kakimir> I bet not
2015-09-26T23:56:08 < Laurenceb__> just estimate lol
2015-09-26T23:56:15 < Laurenceb__> it doenst make too much difference
2015-09-26T23:56:51 < Laurenceb__> about 50ppm if you are out by ~10pF in my experience
2015-09-26T23:56:53 < kakimir> how about find both ends and choosing one in the middle
2015-09-26T23:57:43 < kakimir> can you measure it from frequency or jitter?
2015-09-26T23:57:57 < kakimir> with software and external clock input?
2015-09-26T23:58:46 < kakimir> I need to buffer my rubidium soon

2015-09-27T00:54:35 < decimad> 50 ppm is a lot! ;)
2015-09-27T00:55:01 < Laurenceb__> yeah but thats with 10pF error iirc
2015-09-27T00:55:10 < decimad> I could not believe how bad computer clocks really are, when I started worrying about that...
2015-09-27T00:55:14 < Laurenceb__> if you are arguing over 1pF thats like 5ppm
2015-09-27T00:55:25 < Laurenceb__> so who cares
2015-09-27T00:55:43 < Laurenceb__> xtals are usually >5ppm error, otherwise you use a TCXO

2015-09-27T01:01:10 < emeb> elastic buffer + adaptive rates?
2015-09-27T01:01:26 < upgrdman> Laurenceb__, that ufo youtube video reminded me... i have to use that shitty software at work. wtf can't data logger companies make decent software. that shit looks AND acts like it was ported from DOS or Win3.1
2015-09-27T01:02:28 < decimad> well, say the master provides data at its own frequency of say 1 kHz ... now the slaves consume it at their 1kHz ... if a slave runs fast, it is left without data for a timespan, if it runs slow, it will skip values (and the slaves will only notice that when it happens)

2015-09-27T01:04:33 < decimad> now the slaves could say: dude, send me data, or dude, make slower ... but then they would drift against each other ... so the slave somehow needs to smear or resample the sampled data from the master if they notice they're running fast or slow...

2015-09-27T01:12:09 < decimad> otoh the slave could do the same... but this surely seems to be non-trivial to handle well

2015-09-27T01:45:35 < ColdKeyboard> upgrdman: I saw two types of them, one is for the doors when they are on hinges (I don't know if I spelled this right) and another one is when doors are on "shock absorbers"

2015-09-27T02:19:24 < ColdKeyboard> I have a phobia of eclipse since I never worked with it before, then after I did my firs project with it, for some reason after closing the project I wasn't able to import it back in eclipse... :(
2015-09-27T02:20:03 < decimad> yeah, this workspace concept is a bit strange
2015-09-27T02:21:34 < decimad> but it's free and cross platform... then there are some shitty stripped down eclipse editions like coocox...
2015-09-27T02:22:18 < ColdKeyboard> Yea, that one was even more confusing to use
2015-09-27T02:22:51 < decimad> visual studio has basic gdb support, with which I could debug a running target programmed from eclipse... there isn't missing much actually... make support is there...
2015-09-27T02:22:52 < ColdKeyboard> How do you import project into workspace if it isn't located/from the "original" workspace or whatever the correct term is? :)
2015-09-27T02:23:58 < decimad> so my working is like this: use visual studio 2015 community edition to develop and test constexpr/template stuff... then build with eclipse/arm gcc

2015-09-27T04:49:30 < ColdKeyboard> karlp: I know, I asked in STM32 instead of electronics :)
2015-09-27T04:50:16 < ColdKeyboard> Anyway, I have a great dificulity getting newer chips here in Serbia...
2015-09-27T04:50:30 < ColdKeyboard> Thankfully I'm moving to Canada next year :)
2015-09-27T04:51:08 < aandrew> ColdKeyboard: really? where in Canada?
2015-09-27T04:51:25 < ColdKeyboard> aandrew: Toronto :)
2015-09-27T04:51:32 < aandrew> nice, I'm about an hr away
2015-09-27T04:51:36 < aandrew> I'm in Kitchener
2015-09-27T04:51:46 < zyp> cool, then you could start a pic club ;)
2015-09-27T04:51:50 < ColdKeyboard> Awesome
2015-09-27T04:51:55 -!- Viper168 [~Viper@unaffiliated/viper168] has joined ##stm32
2015-09-27T04:52:11 < ColdKeyboard> zyp: yea ;)
2015-09-27T04:52:21 < aandrew> lol
2015-09-27T04:52:26 < aandrew> there are still tons of pics used
2015-09-27T04:52:34 < zyp> no, seriously, spend your time learning modern chips
2015-09-27T04:52:41 < aandrew> but I agree, paying for a compiler in 2015 is ridiculous
2015-09-27T04:53:04 < aandrew> having proprietary screwy tools such as MPLAB and PicKit3 in 2015 is stupid
2015-09-27T04:53:27 < ColdKeyboard> I agree. However I'm "forced" to use this particular chip :\
2015-09-27T04:53:27 < aandrew> Microchip has spent a pile of money trying to create this ecosystem but ARM is killing them
2015-09-27T04:53:34 < zyp> idk, people still pay for armcc/keil/etc
2015-09-27T04:53:38 < aandrew> AVR is in the same boat, but at least their compiler is free
2015-09-27T04:53:53 < zyp> well
2015-09-27T04:53:53 < aandrew> zyp: yes, we call those people idiots :-)
2015-09-27T04:54:16 < ColdKeyboard> Microchip also has free compilers but they are really crappy
2015-09-27T04:54:24 < zyp> the problem about pic is that the arcitecture is outdated and doesn't really apply well to C
2015-09-27T04:54:33 < aandrew> ColdKeyboard: yes, they disable optimization
2015-09-27T04:54:48 < aandrew> zyp: well PIC12 maybe. PIC18/24 are absolutely geared to C
2015-09-27T04:54:52 < zyp> banked memory is shit to deal with
2015-09-27T04:54:55 < ColdKeyboard> And I think (hope) Microchip and Atmel will be pushed out of the market completely by ARM
2015-09-27T04:55:06 < aandrew> my first professional design was on a PIC16C74A
2015-09-27T04:55:16 < aandrew> went from C74A -> F77 -> F877
2015-09-27T04:55:29 < ColdKeyboard> By the chip I'm guessing that was a long time ago? :)
2015-09-27T04:55:45 < aandrew> that particular product ended up being 65% of the company's sales. not bad for a 19yo kid's first project :-)
2015-09-27T04:55:53 < aandrew> ColdKeyboard: yes, this was 1996ish
2015-09-27T04:56:04 < ColdKeyboard> :)
2015-09-27T04:56:23 < aandrew> now my oldest child is 20. a long time ahs passed :-)
2015-09-27T04:57:03 < ColdKeyboard> Time flies :)
2015-09-27T04:58:02 < zyp> there's multiple reasons pic was a bad fit for C; banked memory, only one working register, dedicated call stack…
2015-09-27T04:58:08 < aandrew> yep
2015-09-27T04:58:16 < aandrew> that product was written in assembly
2015-09-27T04:58:17 < ColdKeyboard> The main reason why I'm "lazy" and don't make my own nRF library for PIC is because I'm not planning on using them after this project :)
2015-09-27T04:58:31 < aandrew> monitor three phase voltage/current, phase angle fire, display/kb mux, etc.
2015-09-27T04:58:40 < aandrew> it was a busy little fucker
2015-09-27T04:59:10 < aandrew> ColdKeyboard: you shoudl be able to find a nice nrf24l01+ lib on github and just port the hw access
2015-09-27T05:00:09 < ColdKeyboard> I tried porting Maniacbug's library from GitHub but I was stuck in the middle of the process
2015-09-27T05:01:06 < zyp> why do you even need a lib? isn't nrf24 so simple that you can use it directly?
2015-09-27T05:01:58 < zyp> I mean, grab a header file with definitions if you don't want to write them yourself
2015-09-27T05:02:20 < zyp> but the package structure and shit is really simple, no?
2015-09-27T05:02:47 < ColdKeyboard> Yes it is. However I was trying to avoid writing my own library but at this point it seems inevitable
2015-09-27T05:17:06 < Roklobsta> ColdKeyboard: there is room for low power 8 bit cpus
2015-09-27T05:17:29 < Roklobsta> the days of big atmegas are numbered though
2015-09-27T05:29:40 < zyp> idk, they don't really seem to have much of an advantage over small cortex-m0s
2015-09-27T05:30:29 < mtbg> they mine bitcoins faster than pi
2015-09-27T05:35:56 < upgrdman> so i replaced my portable air conditioned with a dual-hose ac (more efficient) and thought i'd take apart my old ac to save it's compressor for later use. then i realized that the air filter only filtered the cold-side air. wtf. no wonder this unit was shit.  http://www.farrellf.com/temp/portable_air_conditioner.jpg
2015-09-27T05:38:46 < upgrdman> also, any idea why there's rust "dripping" from the copper tubes on the upper radiator? it should just be copper and aluminum, right? they don't rust like that?
2015-09-27T05:44:42 < PeterM> the housing might be made of a thin sheet of galvanized steel or tin
2015-09-27T05:45:06 < PeterM> the radiator housing that surrounds the core that is
2015-09-27T05:45:39 < PeterM> are you just going to keep the compressor  or you going to keep the heat exchangers/radiators too?
2015-09-27T05:47:01 < upgrdman> well for now im planning to keep the comp and radiators.
2015-09-27T05:47:37 < upgrdman> i'd toss the radiators, but i dont want to vent the refridgerant. i have no backyard or garage... so i'd have to vent it to my living room :/
2015-09-27T05:47:55 < upgrdman> or piss off my neighbors and vent it in our hallway :)
2015-09-27T05:48:08 < PeterM> you can use the radiators/jheat exchangers with water, jsut gotta load the water with anti corrosion stuff and use demineralized/diionized water
2015-09-27T05:48:49 < upgrdman> copper doesn't like water?
2015-09-27T05:49:27 < PeterM> when used with dissimilar metals in a closed loop it can corrode very quickly
2015-09-27T05:50:05 < upgrdman> but the dis. metals are on the outside of the copper tube, no?
2015-09-27T05:50:09 < PeterM> also, to vnt it, you coulkd cut the capillary line and feed it out a window or something?
2015-09-27T05:50:19 < upgrdman> good idea
2015-09-27T05:50:39 < PeterM> i mean if you use it to cool say a aluminium waterblock, or a copper waterblock but with nickle plated ifttings etc
2015-09-27T05:50:58 < upgrdman> oh ok
2015-09-27T05:51:12 < upgrdman> what if i couple to the copper coil with silicone tubing? then no problem?
2015-09-27T05:53:07 < PeterM> if you still have dissimilar metals and you dont use deionized water and or anti corrosion stuff, the water is slightly conductive and you get slight electrolytic corrosion, dissolving mroe ions into the water makeing it more conductive making everythign worse
2015-09-27T05:53:21 < PeterM> if its jsut copper and silicone tubing and water you're fine though
2015-09-27T05:53:34 < upgrdman> ok. TIL. thanks.

2015-09-27T07:44:35 < ReadError> ya him
2015-09-27T07:45:02 < PeterM> the box caps are "run capacitors" and the big electro is a start capacitor
2015-09-27T07:45:34 < upgrdman> can either of them handle high ripple currents?
2015-09-27T07:46:09 < PeterM> the run caps, yeah, a bit
2015-09-27T07:46:26 < upgrdman> guess i could try them on my little induction heater
2015-09-27T07:46:34 < upgrdman> approx 30A ripple current
2015-09-27T07:47:07 < PeterM> they'll probably handle it better than the tiny cerams
2015-09-27T07:47:10 < PeterM> but not  much
2015-09-27T07:48:12 < upgrdman> and, you said the can one is electro? but its an AC cap...
2015-09-27T07:48:58 < PeterM> you can get  non polarized electros
2015-09-27T07:49:19 < upgrdman> oh ya. i think i have some little ones from NTE.
2015-09-27T07:49:43 < upgrdman> so is it so big for 250V 60uF ?
2015-09-27T07:49:47 < upgrdman> so why is it*
2015-09-27T07:50:35 < PeterM> because its nonpolarized
2015-09-27T07:51:49 < PeterM> the little oens are designed to be connected practically accross the mains for teh entire motors life
2015-09-27T07:52:02 < PeterM> the big one is jsut there to provide extra torque during starting
2015-09-27T07:53:28 < upgrdman> and puts caps across mains is to reduce emi?
2015-09-27T07:54:54 < PeterM> they ac couple a second winding on the motor to provide an out of phase voltage to ti
2015-09-27T07:55:28 < PeterM> so it is essentially accross the mains

2015-09-27T08:41:50 < upgrdman> wonder how they will tolerate 40 - 90 kHz
2015-09-27T08:41:58 < upgrdman> guess there's only one way to find out for sure
2015-09-27T08:42:58 < PeterM> oh, 40-90khz should be nothing

2015-09-27T11:26:41 < decimad> jpa- it's enough to get the boring stuff running quickly, and then there's hardware support to do the nifty stuff
2015-09-27T11:29:43 < jpa-> yet only a bit more advanced timer api does a lot more for even the nifty stuff
2015-09-27T11:31:08 < decimad> but it will still not suffice for all cases... iirc chibios introduced tickless and high precision timers... but it's not worth the change in licensing imho
2015-09-27T11:31:44 < jpa-> i don't really like how the chibios high precision timers were done
2015-09-27T11:32:31 < decimad> the os vendors can't know that I don't want high precision timing using systick or something, i need scheduling by the ptp clock...
2015-09-27T11:33:25 < jpa-> at one work project i have simply      typedef uint64_t systime_t; systime_t get_systime(); void schedule_callback(systime_t time, void (*callback)(void*), void* arg);
2015-09-27T11:33:49 < jpa-> at the same time also gets rid of annoying bugs that occur when uint32_t counters overflow
2015-09-27T11:34:54 < jpa-> actually i think it is    typedef int64_t systime_t;   to get rid of annoying comparison bugs also

2015-09-27T13:43:41 < dongs> it was some 4 or 6 port thing
2015-09-27T13:43:44 < dongs> that took 2.0 devices
2015-09-27T13:43:48 < dongs> and trunked them over usb 3

2015-09-27T13:43:56 < dongs> doing it the super dumb way in 3.0
2015-09-27T13:44:01 < dongs> and just having usb2 hub on the 2.0 pins
2015-09-27T13:44:24 < zyp> oh, right
2015-09-27T13:44:35 < zyp> is that even supported by the protocol?

2015-09-27T13:44:54 < zyp> or was it a full EHCD that happened to be connected over usb3?

2015-09-27T13:46:30 < zyp> jpa-, well, you can use it as «interrupt me in n cycles»
2015-09-27T13:47:15 < zyp> but then you can't really use it as an accurate way to tell how much time passed
2015-09-27T13:47:31 < zyp> because you're losing accuracy every time you change the timeout
2015-09-27T13:47:46 < jpa-> ah, right
2015-09-27T13:47:59 < jpa-> preload missing
2015-09-27T13:48:29 < zyp> a free running upcounting timer with a separate deadline register would be much more appropriate
2015-09-27T13:48:41 < jpa-> could use DWT as the "how much time passed" separately, though
2015-09-27T13:48:43 < zyp> i.e. any other timer with a compare channel

2015-09-27T15:15:26 < PeterM> no idea, but i'd guess 4.2v would be 100% safe
2015-09-27T15:15:53 < jpa-> so at most 2S pack?
2015-09-27T15:16:37 < jpa-> i'm planning to add schottkys in parallel in my 10S pack so that the protection circuits can still do their job - but it's annoying having to have one pretty beefy diode per cell
2015-09-27T15:16:52 < jpa-> perhaps i should look into more complex whole-pack protection chips

2015-09-27T15:25:51 < PeterM> ahhh
2015-09-27T15:26:04 < jpa-> if a cell fails, protection circuit will disconnect => instant -40V over protection circuit => funny stuff

2015-09-27T15:36:03 < PeterM> ahhh
2015-09-27T15:36:22 < PeterM> in that case i'd most vertainly want pack level protection
2015-09-27T15:36:34 < jpa-> why?
2015-09-27T15:37:09 < PeterM> because if you drop a cell and bypass it with a diode you could not know it until you ahve a ball of fire between your legs
2015-09-27T15:37:38 < jpa-> why would it fire up in that situation?
2015-09-27T15:37:51 < jpa-> the per-cell protection circuit would have disconnected it anyway
2015-09-27T15:38:34 < PeterM> the cell could have in internal short or something, but you wouldnt know because it would be bypassed, you keep riding, you get a fire between your legs
2015-09-27T15:39:10 < jpa-> so in alternative case, the controller shuts down and i do what to prevent the fire?
2015-09-27T15:39:50 < PeterM> get off teh bike, unplug the pack and remove it from the bike? you still ahev a fire but your bike isn't part of it
2015-09-27T15:40:10 < jpa-> any ideas about handling cell internal failures would be very welcome - i'm not that worried about fire while biking, but fire while charging would not be nice
2015-09-27T15:40:55 < jpa-> it's not like i'll leave the battery pack on the roadside, nor skip work for the day - so it'll be on my bike anyway
2015-09-27T15:45:44 < PeterM> i dunno, i feel that if all the cells have experiencedthe same lifetime conditions and one from the pack fails, fuck it, the pack is dead to me

2015-09-27T15:48:42 < jpa-> not really point wasting 60mohm series resistance on per-cell protection if it cannot work anyway due to reverse voltage
2015-09-27T15:49:22 < jpa-> ReadError: no, it does not - because the cell protection fails immediately because it gets -40V over it after it disconnects

2015-09-27T19:36:44 < upgrdman> zyp, what the difference between a "free running timer" and systick?
2015-09-27T19:37:41 < zyp> systick is a downcounting timer, starting at the interval and counting down to 0
2015-09-27T19:38:06 < zyp> a free running timer is a timer that runs continously to wraparound, independent of the target
2015-09-27T19:38:29 < zyp> and then you have a separate deadline register to match against
2015-09-27T19:39:20 < upgrdman> so free running can interupt you at the deadline, but keep running like normal in the background?
2015-09-27T19:39:29 < zyp> yes
2015-09-27T19:39:44 < upgrdman> ok thx

2015-09-27T19:40:41 < zyp> the counter register will contain the low part of the system time, so you can reference any deadline against that
2015-09-27T19:41:37 < zyp> it's pretty hard to use systick in a tickless manner
2015-09-27T19:46:22 < dongs> The Zano's ability to stop in mid-air and hold its position and then return to home at the tap of a button is really impressive ... or would have been had they shown that. Instead I see a drone that is LESS capable than the $50 toy on my desk. I have a very bad feeling about this.

2015-09-27T19:52:52 < Steffanx> Not sure why im surprised
2015-09-27T19:54:03 < jpa-> the video looks like it is cut always at the point where the zano crashes somewhere :P
2015-09-27T19:56:02 < dongs> the one with zano not yawing?

2015-09-27T21:29:40 < upgrdman> kakimir, its useful for someone who just want to see a fucking schematic
2015-09-27T21:29:45 < upgrdman> err useLESS
2015-09-27T21:30:05 < upgrdman> ya. wtf. schematics as pdf or jpg (if one page) are so much better
2015-09-27T21:37:20 < karlp> especially when the tarball contains files like "kicad-broken" and "blah.bak" and "kicad-new" and shit
2015-09-27T21:37:37 < upgrdman> lol
2015-09-27T21:38:20 < decimad> kicad uses shouting classes
2015-09-27T21:38:27 < decimad> and avoids namespaces
2015-09-27T21:38:58 < decimad> Hey, I'm a KICAD_CLASS
2015-09-27T21:40:14 < decimad> I really wanted to add an instancing facility to it... but I could just not do it... constant friction...
2015-09-27T21:40:16 < ReadError> i remembered I tried to find a copy of kicad for windows
2015-09-27T21:40:20 < ReadError> it wasnt trivial
2015-09-27T21:40:55 < decimad> it looks to me as if it started by some engineer who wasn't really a good coder...
2015-09-27T21:41:08 < ReadError> ole dick
2015-09-27T21:41:22 < BrainDamage> isn't that the usual pattern tough?
2015-09-27T21:41:37 < BrainDamage> like you need a specialized software and you make it for yoursel
2015-09-27T21:42:13 < karlp> https://www.own-mailbox.com/src/Own-Mailbox2.tar.gz if anyone's super keen on making a pdf and commenting onit :)
2015-09-27T21:42:43 < decimad> sure... it's just like they missed so many opportunities to refactor the basic stuff, that now everything depends on that
2015-09-27T21:43:39 < decimad> You can't go in there as a developer and improve a tiny bit... it bleeds through the whole source
2015-09-27T21:44:38 < BrainDamage> that lovely schematic references libs with absolute paths to the home dir of the author
2015-09-27T21:44:39 < BrainDamage> a++
2015-09-27T21:44:50 < decimad> Do you know a pcb software which supports instancing circuits and schematics comfortably?
2015-09-27T21:45:09 < decimad> not even eagle can do it, i believe...
2015-09-27T21:45:20 < zyp> «not even»?
2015-09-27T21:45:36 < zyp> eagle isn't particularly advanced
2015-09-27T21:45:45 < decimad> well, they charge a price, that's what I mean
2015-09-27T21:46:05 < decimad> so I guess you need to go 4 digits for such a basic functionality any normal coder would implement right away?
2015-09-27T21:46:23 < zyp> altium lets you do hierarchical schematics with instances of sub-schematics
2015-09-27T21:46:30 < zyp> but I'm not sure how comfortable it is
2015-09-27T21:46:38 < zyp> haven't used it myself yet

2015-09-27T22:09:57 < karlp> decimad: what do you mean by "instancing" circuits?
2015-09-27T22:10:54 < decimad> it might be a c++ish term... I'm saying "declare a template" and replicate it n times with instanced net names
2015-09-27T22:11:53 < karlp> that's what I thought.
2015-09-27T22:12:11 < karlp> while it's probably nice, it's not really number 1 list of must have features

2015-09-27T22:15:46 < decimad> so I was thinking, yay, you could implement that in kicad... and then I saw kicads source
2015-09-27T22:16:36 < Steffanx> when was that decimad?

2015-09-28T00:32:00 < kakimir> how is projects guys
2015-09-28T00:33:34 < karlp> receiving take downs...
2015-09-28T00:34:12  * [7] just tossed his PCB design into the trash and started over
2015-09-28T00:35:11 < [7]> why do microsd cards have to be so huge! :P
2015-09-28T00:36:47 < Roklobsta> you need femtosd
2015-09-28T00:37:00 < PeterM> i wonder how practical it would be so mount a micro sd card dfn style
2015-09-28T00:37:22 < [7]> might actually work with reflow
2015-09-28T00:37:41 < [7]> but I guess you can't hand solder such a thing ;)
2015-09-28T00:37:53 < [7]> the pads don't extend all the way to the edge
2015-09-28T00:38:48 < karlp> PeterM: I've seen it done, on hackaday even iirc.
2015-09-28T00:39:14 < PeterM> karlp in that case i'd forget aboutit and jsut use a socket
2015-09-28T00:41:26 < karlp> tell 7, I have a socket on my project with a uSD card :)
2015-09-28T00:55:35 < [7]> yeah I have as well, but it's blocking a bit more PCB area than I'd like it to...
2015-09-28T00:56:11 < [7]> especially if you want to make a board that plugs into a breadboard with two rows of pin headers, a microsd slot can become a limiting factor rather quickly
2015-09-28T00:56:39 < [7]> I'm basically locked into 700 mils of width
2015-09-28T00:59:36 < upgrdman> so stand the card up on end and solder it?

2015-09-28T01:05:50 < [7]> probably easier to fix it by just adding more layers to the board, but I want to keep the cost down as well
2015-09-28T01:06:10 < [7]> the finished kits should be as affordable as possible ;)
2015-09-28T01:06:25 < [7]> like $5 in parts or something
2015-09-28T01:11:50 < karlp> there's those sd card slots that are only the very edge,
2015-09-28T01:12:05 < karlp> super fragile though, wouldn't want to put it in a kit for breadboarding

2015-09-28T04:13:27 < dongs> talsit: i have components like this: http://i.imgur.com/v4MaouH.png
2015-09-28T04:13:56 < dongs> top copper region for the outline, and pads for solder tabs
2015-09-28T04:20:15 < upgrdman> dongs, that "knob gobbler" actually looks somewhat useful, if retarded
2015-09-28T04:26:39 < dongs> sure
2015-09-28T04:26:43 < dongs> the namae is teh best part tho
2015-09-28T04:26:49 < dongs> name, too
2015-09-28T04:27:10 < dongs> made in usa tho, they've fucked themselves out of ever makign any profit
2015-09-28T04:28:12 < talsit> dongs: so, no mech13,mech15 layers?
2015-09-28T04:28:38 < dongs> for what?
2015-09-28T04:28:56 < dongs> i sometimes put a translucent rectangle on it for 3d purposes
2015-09-28T04:28:59 < dongs> i didnt on that one
2015-09-28T04:33:00 < talsit> just asking
2015-09-28T04:33:20 < talsit> the mech15 layer seems to be the one over which altium chucks a hissy fit
2015-09-28T04:34:23 < dongs> er,, why would it be?
2015-09-28T04:34:29 < dongs> unless you wr ote a rule for it

2015-09-28T04:37:25 < talsit> the default rules basically chuck the hissy fit because it claims of component overlap
2015-09-28T04:37:55 < dongs> if you actually care aboiut that, make a new overlap rule InComponent(YourSHieldThing) and set clerance to 0/0
2015-09-28T04:38:01 < dongs> or else just set clearance to 0

2015-09-28T04:41:13 < gxti> i suggest giving it an actual 3d model, even if it's crude
2015-09-28T04:41:37 < dongs> talsit: you did it wrong then
2015-09-28T04:41:39 < gxti> any parts without a model are assumed to be infinitely tall, i think
2015-09-28T04:42:24 < talsit> gxti: will try that
2015-09-28T04:42:31 < dongs> the problem there is not model
2015-09-28T04:42:36 < talsit> dongs: i know, hence me asking like a n00b

2015-09-28T04:44:02 < dongs> i dont see any actual pads connected to that outline
2015-09-28T04:44:06 < dongs> how are you connecting it to a net?
2015-09-28T04:44:23 < dongs> do you have some top-layer smt pads that arent visible?
2015-09-28T04:44:26 < talsit> component collision
2015-09-28T04:44:33 < talsit> not et
2015-09-28T04:44:35 < talsit> *yet
2015-09-28T04:44:39 < gxti> yeah that's a model problem, not anything electrical
2015-09-28T04:45:18 < dongs> gxti: wat woudl you do then.
2015-09-28T04:45:26 < gxti> make a model for the shield
2015-09-28T04:45:33 < talsit> just a simple extruded?
2015-09-28T04:45:39 < dongs> something more involved than just a slab?
2015-09-28T04:45:52 < gxti> something that doesn't occupy the middle part where the other components are
2015-09-28T04:45:55 < dongs> im thinking he means to make an actual shield model
2015-09-28T04:45:56 < dongs> yeah
2015-09-28T04:46:04 < gxti> you can do it with simple boxes
2015-09-28T04:46:10 < gxti> just draw 4 boxes over the 4 walls
2015-09-28T04:46:18 < dongs> an, right
2015-09-28T04:46:20 < dongs> and a box on top
2015-09-28T04:46:25 < dongs> to cover it up.
2015-09-28T04:46:31 < dongs> i suppose that might work.
2015-09-28T04:46:50 < gxti> optionally yeah
2015-09-28T04:47:15 < gxti> i'd probably leave it off so i can see what's under, but if you add it then you can do actually clearance checks
2015-09-28T04:47:27 < dongs> gxti: er, you can set transparency of extruded shit

2015-09-28T04:47:29 < gxti> but until you add *some* model it's assuming the component is a solid box occupying that whole area
2015-09-28T04:47:30 < dongs> to like 20%
2015-09-28T04:47:32 < dongs> tehn you can stil lsee stuff
2015-09-28T04:47:32 < gxti> true
2015-09-28T04:47:50 < dongs> like i said other shield model i did, i just slapped a transparent rectangle over it.
2015-09-28T04:48:02 < dongs> but I usually just turn of fcomponent clearance rule
2015-09-28T04:49:24 < talsit> hey, that worked, cheers
2015-09-28T04:49:34 < talsit> just drew 4 walls
2015-09-28T04:49:37 < talsit> left the top off
2015-09-28T04:50:35 < talsit> i'll probably just make something in solidworks
2015-09-28T04:50:49 < talsit> but for the moment, it's 99.5% less annoying

2015-09-28T07:20:12 < talsit> i thought of doing as if it was flex boards
2015-09-28T07:20:25 < dongs> i havent poked wiht flex stuff on altidong at all
2015-09-28T07:20:29 < dongs> so i dont evne know how it works
2015-09-28T07:20:33 < talsit> and define bending areas and then just v-cut them off
2015-09-28T07:20:44 < talsit> me neither, just thought of that as an option
2015-09-28T07:20:59 < dongs> youre gonna end up having to "panel" your board anyway
2015-09-28T07:21:08 < gxti> nah i haven't done anything fancy, i just use separate projects
2015-09-28T07:21:24 < talsit> not yet - still only doing <10qty runs
2015-09-28T07:21:29 < dongs> no i mean
2015-09-28T07:21:42 < dongs> even flex, gerber export will be a single sheet right

2015-09-28T08:07:17 < tylerdurden> Hi I am using a GSM module and controlling it with stm32l MCU but it goes to hardfault when call is made to GSM, i was assuming that it is due to interference. What might be the exact reason for this error??
2015-09-28T08:08:47 < tylerdurden> I checked the pins with the scope and the pin which i configured for led goes high whenever a voice call is made. Is this the reason for hardfaults?
2015-09-28T08:09:12 < jpa-> tylerdurden: what does the CFSR say as the reason for hardfault?
2015-09-28T08:09:28 < jpa-> what line does the debugger say the hardfault occurred on, does it vary?
2015-09-28T08:09:51 < jpa-> do you have any reason to rule out your software simply crashing?
2015-09-28T08:10:55 < tylerdurden> CFSR most of the time i got is as memmanage fault
2015-09-28T08:11:04 < tylerdurden> yes the line varies
2015-09-28T08:11:31 < tylerdurden> i am running a while(1) loop for testing and i made a voice call to the device and found that it goes to hardfault
2015-09-28T08:11:58 < jpa-> ok, so sounds like interference indeed
2015-09-28T08:12:37 < jpa-> how is your schematic and layout? do the modem and stm32 share power supplies?
2015-09-28T08:12:40 < tylerdurden> jpa--is there any way to make the pins not respond to the interference . some way to configure
2015-09-28T08:13:00 < tylerdurden> yes 3.7V battery is shared
2015-09-28T08:13:22 < jpa-> what is the internal resistance of battery? how much capacitors do you have and what ESR do they have?
2015-09-28T08:13:42 < jpa-> have you checked how the power rail looks on a fast scope?
2015-09-28T08:14:19 < jpa-> what is the drop-out voltage of your (3V? 3.3V?) ldo for the processor?
2015-09-28T08:14:31 < tylerdurden> No but i checked all the common grounds on the pcb and it fluctuates whenever a call is made
2015-09-28T08:14:42 < jpa-> fluctuates compared to what?
2015-09-28T08:14:44 < tylerdurden> its 3.3V .
2015-09-28T08:16:00 < tylerdurden> Initially the plot is stable when all common grounds are observed and as soon as call is made the voltage value goes to 200mV
2015-09-28T08:16:41 < jpa-> 200mV compared to what reference point?

2015-09-28T08:18:13 < jpa-> eh
2015-09-28T08:18:26 < tylerdurden> so i tried to shield the MCU with aluminium foil but no luck
2015-09-28T08:19:25 < jpa-> GND fluctuates by 200mV compared to 0V.. not sure how i should parse that :)
2015-09-28T08:19:49 < talsit> 0V != GND?
2015-09-28T08:20:11 < jpa-> do you have a solid ground plane? if not, is the GSM power supply traces dimensioned for 2A peak loads, and routed separate from other grounds to the battery connector?
2015-09-28T08:21:39 < tylerdurden> yeah the ground plane is messed up but right now we dont have time to redesign a new pcb. Is there any way to configure the unused pins to resolve the issue temporarily
2015-09-28T08:22:22 < tylerdurden> right now i have the luxury to change only the software
2015-09-28T08:24:26 < jpa-> i doubt you can resolve this issue in software.
2015-09-28T08:25:04 < jpa-> do you have a reason to believe the interference comes through io pins, and not through the power supply pins?
2015-09-28T08:25:29 < jpa-> putting the unused io pins to output mode should resolve the issue if they come from there, though
2015-09-28T08:25:32 < talsit> can you try adding some bulk caps to see if it improves?

2015-09-28T08:26:48 < tylerdurden> i have an output pin connected to led and it goes high and blinks the led whenever a call is made
2015-09-28T08:26:54 < jpa-> i would try cutting the gsm's connection to local ground and power and solder flywires for it
2015-09-28T08:27:11 < jpa-> tylerdurden: well that is more probably due to the cpu going wonky
2015-09-28T08:28:22 < jpa-> adding capacitors will help also if you currently have too few - perhaps you can change a few caps to a bigger capacitance versions?
2015-09-28T08:29:12 < tylerdurden> ok i will check with the bigger capacitors if possible
2015-09-28T08:29:35 < jpa-> fix the ground also
2015-09-28T08:29:52 < jpa-> apparently this is just a proto so flywires should be enough
2015-09-28T08:30:27 < tylerdurden> I tried the flywires last week it didnt work...same issue
2015-09-28T08:31:08 < jpa-> did you remove the connection to local ground, in order to make it star-grounded?
2015-09-28T08:31:52 < tylerdurden> yeah the ground trace is disconnected to battery
2015-09-28T08:37:25 < mtbg> what is between microcontroller supply pins and the battery, and also gsm module supply pins and the battery?
2015-09-28T08:37:40 < mtbg> some kind of dc-dc converter, or LDO?
2015-09-28T08:38:07 < tylerdurden> btw MCU and battery--> LDO
2015-09-28T08:38:28 < tylerdurden> gsm direct connection to battery

2015-09-28T13:04:42 < Lux> on the stm32f405 mcus, do i need anything else than 22ohm series resistors for the usb interface to work ?
2015-09-28T13:06:15 < Ecco> Lux: Apparently you don't need anything, just plug it straight away
2015-09-28T13:06:31 < jpa-> copy the discovery board schematics :P
2015-09-28T13:06:42 < jpa-> i can't remember if that specific one has the pull-up internally
2015-09-28T13:06:47 < Ecco> (sure the resistor is better, but from what I understood last time we talked about this subject here, they're not even needed)
2015-09-28T13:06:52 < jpa-> and in some cases you might want to be able to sense the Vbus also
2015-09-28T13:07:44 < Lux> i copied the discovery board design without that esd chip
2015-09-28T13:07:51 < Ecco> esd chip?
2015-09-28T13:07:57 < Lux> maybe something else is fucked up
2015-09-28T13:08:08 < jpa-> hm, my STM32F407 design does not have the series resistors.. IIRC they are internal
2015-09-28T13:09:28 < Lux> Ecco: EMIF02-USB03F2
2015-09-28T13:09:52 < Ecco> Oh, interesting
2015-09-28T13:09:56 < dongs> jpa-: anything with OTG would have it inside
2015-09-28T13:09:58 < Ecco> I had no idea this even existed
2015-09-28T13:10:01 < dongs> i guess?
2015-09-28T13:10:08 < dongs> or anything with USB bootloader
2015-09-28T13:10:12 < dongs> eyah, teh 2nd
2015-09-28T13:10:19 < dongs> cuz.. USB bootloader needs to be able to pull up the line
2015-09-28T13:10:28 < Ecco> What happens if you don't use an EMI filter / ESD protection chip?
2015-09-28T13:10:33 < dongs> you get FRIED
2015-09-28T13:10:44 < dongs> Lux: esd wouldnt matter
2015-09-28T13:10:48 < Ecco> That's for the ESD part right?
2015-09-28T13:10:58 < dongs> they're straight through parts anyway
2015-09-28T13:10:58 < Ecco> How can this happen, in practice ? And how likely is it?
2015-09-28T13:11:04 < Lux> so i don't need any pullups ?
2015-09-28T13:11:06 < dongs> no
2015-09-28T13:11:11 < Lux> good
2015-09-28T13:11:13 < dongs> not on any chip with usb bootlaoder
2015-09-28T13:11:18 < dongs> you sure you didnt swap D+/D-
2015-09-28T13:11:30 < Lux> that's probably the case :/
2015-09-28T13:11:38 < jpa-> hmm, STM32F407 discovery *does* have the 22 ohm series resistors, but in combination with the funnychip (tm)
2015-09-28T13:11:43 < dongs> is your schematic in EAGLE
2015-09-28T13:11:54 < Lux> nah altium, but i didn't design it
2015-09-28T13:12:06 < Lux> my colleague also put in 68ohms
2015-09-28T13:12:13 < Lux> yay
2015-09-28T13:12:24 < dongs> 68ohm in series?
2015-09-28T13:12:26 < jpa-> while the funnychip (
2015-09-28T13:12:38 < Lux> yep
2015-09-28T13:12:42 < jpa-> EMIF02-USB03F2) has 33 ohm internally in parallel with the external 22 ohm
2015-09-28T13:12:53 < dongs> oh, hah.
2015-09-28T13:13:02 < dongs> thats why if I do usb protection i just use non-weird shit
2015-09-28T13:13:15 < dongs> something that just sits on the lines in passthrough mode
2015-09-28T13:13:17 < dongs> not active shit
2015-09-28T13:13:20 < jpa-> yeah, i just have PRTR5V in parallel with the usb lines
2015-09-28T13:13:22 < dongs> Rclamp02something or ot her
2015-09-28T13:13:23 < dongs> yeah
2015-09-28T13:13:51 < karlp> Lux: any idea where that 68ohm came from? I just took off 68ohm resistors a colleague of mine put on :)
2015-09-28T13:13:56 < jpa-> but that st chip does some EMI filtering also apparently
2015-09-28T13:14:15 < dongs> besides
2015-09-28T13:14:20 < dongs> this is FS-USB on F4
2015-09-28T13:14:25 < dongs> it needs no filtering
2015-09-28T13:14:29 < jpa-> karlp: 5V avr's driving vusb? http://www.frank-zhao.com/pics/usbbusinesscard_circuit.png
2015-09-28T13:14:45 < dongs> ror
2015-09-28T13:14:51 < dongs> fucking awful
2015-09-28T13:15:18 < karlp> I wonder if that all goes back to someone not having the right sized resistors back in the day, and saying, "I used the smallest I had, it worked" and now we keep seeing it copypasta'd all over the world?
2015-09-28T13:15:35 < karlp> I haven't read the usb1 spec, but usb2 says it should be whatever you need to make 50ohms
2015-09-28T13:15:48 < karlp> and I can't imagine many situations where you need >50 to get to 50.
2015-09-28T13:16:16 < mtbg> I wonder if there are any commercial products based on avr + vusb
2015-09-28T13:16:23 < karlp> mtbg: you bet
2015-09-28T13:16:26 < mtbg> with these zener diodes on USB data lines
2015-09-28T13:16:49 < mtbg> there surely is usbasp programmer
2015-09-28T13:17:02 < mtbg> which is sold commercially by multiple manufacturers
2015-09-28T13:17:08 < dongs> haha
2015-09-28T13:17:10 < mtbg> but, anything more serious?
2015-09-28T13:17:30 < dongs> probably s omething on dickstarter
2015-09-28T13:18:16 < jpa-> karlp: for AVR crap, the 68 ohm is due to their 3.3V zeners, i.e. to limit maximum current from IO to 25mA
2015-09-28T13:20:24 < Lux> karlp: apparently some random schematic on the internet
2015-09-28T13:20:26 < dongs> ID LIKE TO ADD YOU TO MY PROFESSIONAL NETWORK ON DICKED-IN
2015-09-28T13:20:47 < Lux> so googled usb stuff and copied what he found
2015-09-28T13:21:03 < dongs> lux, is this for your clonefc, or some unrelated work
2015-09-28T13:21:13 < dongs> you should stop having "colleagues" that google schematics
2015-09-28T13:21:24 < dongs> it's gonna end like a typical dickstarter
2015-09-28T13:21:51 < jpa-> eh, when they google schematics, i can then google the codes
2015-09-28T13:22:06 < dongs> Dear Supporters,
2015-09-28T13:22:07 < dongs> We really apologize for lack of updates. We are about to complete the complex internal circuits and LED assembling, the same will be done by end of October.

2015-09-28T15:39:33 < Laurenceb__> who needs eMMC
2015-09-28T15:40:53 < Laurenceb__> stick it on a SD card footprint pcb with microcontroller and itd be a good datalogger
2015-09-28T15:41:50 < PaulFertser> Laurenceb__: didn't you have enough fun with SD cards? ;)
2015-09-28T16:05:21 < scrts_w> I saw DRAM and eMMC in one package
2015-09-28T16:05:33 < scrts_w> seemed useful for processors
2015-09-28T16:10:44 < dongs> scrts_w: cheap chinatrash phoens use that
2015-09-28T16:10:54 < dongs> the size is not very big
2015-09-28T16:10:58 < dongs> either dram or emmc

2015-09-28T16:21:20 < dongs> Regarding the laggy video. Those videos were shot with the app in photo mode so only running very low FPS. In video mode (which is what the next set of videos will use) you should see a huge improvement in frame rate and reduction in lag.

2015-09-28T23:35:10 < kakimir> good almost midnight guys
2015-09-28T23:44:47 < kakimir> have you ever concidered why
2015-09-28T23:45:49 < Ecco> why what?
2015-09-28T23:46:27 < kakimir> society and technology is still so primitive
2015-09-28T23:46:41 < Ecco> philosophy time?
2015-09-28T23:47:24 < kakimir> and most of things we know or are in our "scope" have come up latelly
2015-09-28T23:53:20 < kakimir> I wonder if aliens have something to do with it
2015-09-28T23:53:53 < ColdKeyboard> Is there a built in function like strstr() that would return the integer representing where does the needle exist in the haystack?
2015-09-28T23:54:21 < mtbg> I believe there are many factors that contribute to it, but major reason can be that most people can't think for themself
2015-09-28T23:54:59 < mtbg> they are taught to memorize rules and facts, instead of developing their own, consistent model of reality

2015-09-28T23:55:37 < kakimir> by who?
2015-09-28T23:56:29 < mtbg> by their environment, and mostly by public education
2015-09-28T23:56:44 < kakimir> you think it just happen to be there?
2015-09-28T23:56:52 < kakimir> doing it's thing
2015-09-28T23:58:37 < mtbg> no one really researched and developed the way of educating people, it just emerged itself not so long ago in almost its current form
2015-09-28T23:59:05 < mtbg> there was not so much and not so deep things to understand and learn back then
2015-09-28T23:59:49 < mtbg> but it happens to be really blasphemous for human cognition
2015-09-28T23:59:52 < kakimir> what if there was generation zero and all before that is just story?
--- Day changed Tue Sep 29 2015
2015-09-29T00:00:14 < mtbg> considering what we evolved to
2015-09-29T00:01:26 < kakimir> I can't help thinking sometimes that we are generation zero
2015-09-29T00:01:37 < mtbg> too little individualism, and too little freedom in one's own development
2015-09-29T00:02:32 < mtbg> what you mean, that all before is "just story"?
2015-09-29T00:03:05 < kakimir> just a plant image of the past
2015-09-29T00:04:24 < kakimir> that has no validity

2015-09-29T00:04:35 < mtbg> I sometimes wonder that we, in general, spend too much time and effort in analysis and, what is worse, cultivation of past things even if there are much better ways to do something
2015-09-29T00:05:19 < mtbg> instead of applying standard logical reasoning considering current state
2015-09-29T00:07:55 < ColdKeyboard> How do I redirect printf() to SWO of ST-Link2?
2015-09-29T00:07:56 < kakimir> logical reasoning says to me that I need to chill a lot

2015-09-29T00:10:29 < kakimir> is there such thing as swo putchar.. must be.
2015-09-29T00:10:31 < Steffanx> you could also try to go sleep early and have some nice dreams kakimir

2015-09-29T00:43:54 < kakimir> I meant myself
2015-09-29T00:44:51 < mtbg> the further we go away from what we evolved to, the less productive and more just resource-wasting people become
2015-09-29T00:45:30 < mtbg> no one benefits from it

2015-09-29T05:52:21 < dongs> Buying used airbags is a viable solution for rebuilding crashed vehicles!
2015-09-29T05:52:22 < dongs> But are recycled airbags safe to use?
2015-09-29T05:52:22 < dongs> As a company who has been distributing airbags since 1999 it is our opinion that used airbags are a safe alternative for vehicles who are totaled solely on the replacement cost of new airbags. But more importantly, they are a viable solution for individuals who can not afford to buy new airbags based on the current blue book value of their vehicle. However, it is important to educate yourself to learn about critical differences when purcashing a used airbag.

2015-09-29T05:55:48 < upgrdman> nsfw recycling  http://imgur.com/gallery/65A3LlE
2015-09-29T05:55:50 < dongs> well, its just stm32 with tarduino headers right
2015-09-29T05:56:17 < FAalbers> I have a question about USART2 on the STM32F401RE Nucleo board
2015-09-29T05:57:03 < dongs> i have it
2015-09-29T05:57:05 < dongs> (that board)
2015-09-29T05:57:12 < dongs> have you looked at schematics?
2015-09-29T05:57:13 < FAalbers> When I use the USART2 , the STLink makes it a Virtual COM link through the USB . All that works fine
2015-09-29T05:57:25 < FAalbers> dongs yest I have
2015-09-29T05:58:25 < dongs> so whats the problem
2015-09-29T05:58:37 < FAalbers> dongs , the thing is , if I look at the schematics , it says to use PA2/PA3 as TX/Rx , which I do .
2015-09-29T05:59:28 < FAalbers> I activate those pins and initialize them. But When I attach the Logic Analyzer, I see no changing output.
2015-09-29T06:00:27 < FAalbers> Strangely enough , when I use USART6 with the proper pins , it DOES stream the bitstream correctly and I can read with the Logic Analyzer.
2015-09-29T06:01:05 < FAalbers> Is there maybe a setting that sets USART2 to be used as Virtual COM or through the GPIO ?
2015-09-29T06:01:12 < FAalbers> Hope I make senes
2015-09-29T06:01:35 < FAalbers> sense :)
2015-09-29T06:02:34 < dongs> are you using tehse off nucleao board
2015-09-29T06:02:36 < dongs> or on your own shit?
2015-09-29T06:02:43 < dongs> PA2/3 is indeed usart2tx/rx
2015-09-29T06:02:52 < dongs> AF7
2015-09-29T06:02:56 < dongs> did you set AF?
2015-09-29T06:03:34 < FAalbers> On the nucleo board , just started to learn it
2015-09-29T06:03:36 < dongs> there's also jumpers
2015-09-29T06:03:55 < FAalbers> dongs, YEs , GPIO_AF7_USART2
2015-09-29T06:04:26 < upgrdman> stm adc can handle -0.3V right?
2015-09-29T06:04:27 < FAalbers> dongs, Not sure if I mentioned , but when using USART2 the virtual COM does work alright
2015-09-29T06:04:36 < FAalbers> dongs, just not the pins
2015-09-29T06:04:39 < dongs> er?
2015-09-29T06:05:19 < FAalbers> dongs, jumpers ? I kinda expected that, but could not find which ones they are and how to set them
2015-09-29T06:06:18 < FAalbers> dongs, Let me try again , maybe it was just a typo. Will post the actual code in a bit , it's short
2015-09-29T06:06:45 < FAalbers> dongs, Was just asking if there was something obvious I was missing

2015-09-29T06:07:21 < dongs> those are rx/tx lines

2015-09-29T08:17:20 < jpa-> that one also.. maybe it is because they want the leakage current monitor, and it would be disturbed by grounding

2015-09-29T08:22:27 < jubatus> upgrdman: if you have inductors in the power line

2015-09-29T08:23:12 < upgrdman> ya
2015-09-29T08:23:36 < upgrdman> but the current flow would not stop abruptly, it would slow, no? since the load would still draw as the voltage sags
2015-09-29T08:24:19 < jubatus> it happens, and people don't expect it so I mentioned it
2015-09-29T08:24:47 < jubatus> *it happens sometimes
2015-09-29T08:24:50 < upgrdman> sure, but why would it happen?
2015-09-29T08:25:13 < upgrdman> the load is still drawing current, just more slowly as the voltage dips
2015-09-29T08:26:11 < jubatus> drawing from the capacitor, not the inductor (if its an LC filter)
2015-09-29T08:26:36 < jubatus> no that doesn't make sense either

2015-09-29T08:28:26 < jpa-> upgrdman: well yeah, though switch sees a spike also if you switch off a transformer (with or without filters)
2015-09-29T08:28:46 < upgrdman> true
2015-09-29T08:29:01 < jubatus> in my case the spikes were downstream of the CLC filter
2015-09-29T08:29:09 < jpa-> jubatus: do you remember what components got broken by that?
2015-09-29T08:29:24 < jubatus> varistors
2015-09-29T08:29:31 < jubatus> (MOVs)
2015-09-29T08:31:17 < jpa-> was it transformer-based power supply or smps?
2015-09-29T08:31:27 < jubatus> it was a mains filter
2015-09-29T08:31:40 < jubatus> 240V in 240V out
2015-09-29T08:31:43 < jpa-> ah, so unknown load connected?
2015-09-29T08:31:47 < jubatus> yes
2015-09-29T08:31:51 < jpa-> hmm
2015-09-29T08:32:39 < ReadError> problem im running in to, to get the desired current handling I need a fairly large inductor
2015-09-29T08:32:46 < ReadError> (using vanilla LC)
2015-09-29T08:33:18 < ReadError> so was wondering if I could achieve a similar cutoff/current with another type of filter
2015-09-29T08:35:23 < ReadError> but theres probably a lot more i havent come across

2015-09-29T08:41:44 < jpa-> jubatus: hmm, maybe something like this? atleast it gives a spike when i switch it off  http://goo.gl/v5UOyt
2015-09-29T08:44:35 < jubatus> it was a CLC filter basically. is there any particular reason why you've simulated 2 1mH inductors ? should be the same with just one no ?
2015-09-29T08:44:46 < jubatus> how do you simulate switching it off ?
2015-09-29T08:45:07 < jubatus> oh ok
2015-09-29T08:45:39 < jubatus> the numbers were changing too fast for me to read
2015-09-29T08:45:45 < jpa-> ah well, missed the part about it being CLC filter
2015-09-29T08:45:52 < jpa-> there should be a scope display at the bottom
2015-09-29T08:47:13 < jubatus> yeah I think the spike in your simulation is from the transformer, not the inductors
2015-09-29T08:48:39 < jpa-> yeah, probably - but couldn't it been the same for your unknown load?
2015-09-29T08:49:18 < jubatus> no, because the problem went away when we removed the L from the filter
2015-09-29T08:50:51 < jpa-> hm, i wonder how you could get a bigger spike from the filter L than from a transformer
2015-09-29T08:54:07 < jubatus> might have been something related to slew rate. the transformers are iron and slow. the filter was ferrite - so it would have been fast.

You could however, log your friends into your account on their phone. They could then use your Zano. Its one account, multiple Zano's.
2015-09-29T10:14:44 < dongs> people need to actually have zanos to have them stolen
2015-09-29T10:14:55 < dongs> assuming anyone would evne want that shit in the first palce
2015-09-29T10:16:11 < jpa-> maybe they'll report zanos as stolen and recover money from insurance
2015-09-29T10:16:44 < dongs> haha
2015-09-29T10:24:57 < PaulFertser> I wonder what might have been their reasoning when deciding to ship to some UK customers ahead of the die-hard kickstarter "super-early-preorder" fans.
2015-09-29T10:25:07 < dongs> yeah, right?
2015-09-29T10:25:26 < dongs> PaulFertser: rumor is, they can actually lose money on preorders
2015-09-29T10:25:32 < dongs> as they're protected by various EU laws
2015-09-29T10:25:38 < dongs> whereas dickstarter guys are fucked
2015-09-29T10:28:39 < PaulFertser> dongs: heh, I'd expect them to be able to produce as many of those loosy drones as needed by now. It's funny to see how those forum dickheads are still all enthusiastic and keep proposing new "great ideas" and thanking TG etc.
2015-09-29T10:28:52 < PaulFertser> Eh, s/drones/quads/ I meant.
2015-09-29T10:30:13 < dongs> PaulFertser: they made the assembly fucktardedly difficult and requiring tons of manual labor
2015-09-29T10:31:07 < PaulFertser> Heh, that would explain it.
2015-09-29T10:31:18 < dongs> but
2015-09-29T10:31:33 < dongs> they're also clearly not making a shitload because at least someone there fucking knows this stuff cant work

2015-09-29T12:01:13 < dongs> Understandable, but like Ivan said, registration needs to take into account the configuration of a particular Zano and it's calibration profile.
2015-09-29T12:01:16 < dongs> Also, if they don't register they can't use the HPC so don't get the best quality video output. As such, why would they want to buy one if they only had access to the raw video and not the finely tuned HPC video?

2015-09-29T16:51:30 < Ecco> Guys, I've just built something
2015-09-29T16:51:37 < Ecco> and I'd like to know if you find this interesting
2015-09-29T16:51:43 < dongs> mtbg: they shoulda used a galvanometer
2015-09-29T16:51:48 < dongs> instead of a strand
2015-09-29T16:51:58 < Ecco> My current firmware was heavily overflowing the stack I had allocated for it
2015-09-29T16:51:58 < dongs> then you could shave  your ENTIRE FUCKIGN FACE in liek 5 seconds
2015-09-29T16:53:33 < Ecco> so I really wondered "what the hell goes in the stack?"
2015-09-29T16:53:38 < Ecco> So I wrote a valgrind plugin
2015-09-29T16:53:42 < Ecco> that tracks stack usage
2015-09-29T16:53:53 < Ecco> and display a frame-by-frame breakdown of stack usage
2015-09-29T16:58:12 < dongs> well that is cool and all but
2015-09-29T16:58:17 < dongs> if you'd just write non-shitty code to begin wiht
2015-09-29T16:58:24 < dongs> this wouldn't even become a problem
2015-09-29T16:58:35 < dongs> i mean, ways to trash your stack is like...
2015-09-29T16:58:36 < PaulFertser> Ecco: how does that work, where is your firmware running, on your target?
2015-09-29T16:58:50 < dongs> arrays out of bounds, recursion, huge local vars, etc
2015-09-29T16:59:07 < Bundestrojaner> mtbg: Resethandler -> _start() -> initialize_hardware() -> System_Init() -> SetSysClock();
2015-09-29T16:59:42 < dongs> Bundestrojaner: the order doesnt really matter, why not setclock early so the rest of the code runs at full speed isntead of default 8mhz or whatever
2015-09-29T17:00:08 < Bundestrojaner> dongs: this is pretty the first thing it does
2015-09-29T17:00:08 < Ecco> dongs: I'm sorry I don't get it
2015-09-29T17:00:15 < Ecco> I'm not destroying my stack
2015-09-29T17:00:21 < dongs> Ecco: yeah, you're running out of it
2015-09-29T17:00:23 < Ecco> (hopefully though)
2015-09-29T17:00:24 < Ecco> yes
2015-09-29T17:00:28 < dongs> which can only come from shitty coding
2015-09-29T17:00:33 < Ecco> well
2015-09-29T17:00:37 < Ecco> no?
2015-09-29T17:00:38 < Bundestrojaner> _start calls main() after initialize_hardware()
2015-09-29T17:00:38 < Sync> mtbg: obviously pros working on the optical bench without glasses
2015-09-29T17:00:54 < Ecco> I mean, maybe, but in any way, it's very hard to diagnose
2015-09-29T17:01:02 < decimad> I don't overflow my 1 byte stacks
2015-09-29T17:01:07 < decimad> because I'm leet
2015-09-29T17:01:21 < Ecco> PaulFertser: the firmware is running on my PC
2015-09-29T17:01:39 < Ecco> So it's not exactly like it would be on the end device
2015-09-29T17:01:48 < Ecco> but that is similar enough I think
2015-09-29T17:01:53 < dongs> so have you found what hte problem was?
2015-09-29T17:01:56 < Ecco> Yes
2015-09-29T17:02:10 < Ecco> I'm using yacc to parse a file
2015-09-29T17:02:22 < Ecco> and apparently yacc has a 2200 bytes long stack frame
2015-09-29T17:02:32 < dongs> ... lol.

2015-09-29T17:02:57 < dongs> i bet it does lots of actual allocations, too.
2015-09-29T17:03:11 < dongs> also uh
2015-09-29T17:03:13 < Ecco> I haven't checked that
2015-09-29T17:03:22 < dongs> doesnt your gcc tell you you're out of stack when you compile?
2015-09-29T17:03:28 < dongs> i remember armcc did that
2015-09-29T17:03:29 < Ecco> why? no
2015-09-29T17:03:33 < Ecco> How could it know?
2015-09-29T17:03:35 < dongs> well, sux 4 u i guess
2015-09-29T17:03:42 < dongs> duno, by static analysis?
2015-09-29T17:03:45 < mtbg> in such confined environment, maybe writing your own parser is the way to go
2015-09-29T17:03:50 < Ecco> Yeah but that's dynamic behavior
2015-09-29T17:03:55 < Ecco> mtbg: yeah, maybe
2015-09-29T17:04:03 < dongs> shrug
2015-09-29T17:04:07 < Ecco> but that's slightly off-topic
2015-09-29T17:04:12 < Ecco> I think the tool is still useful :)
2015-09-29T17:04:38 < Viper168> ecco the dolphin is here?
2015-09-29T17:04:39 < Ecco> Better than "fill the stack w/ a pattern and see how it looks like after a while"
2015-09-29T17:04:47 < Viper168> why didn't you guys tell me
2015-09-29T17:04:58 < Ecco> With this tool, you can see which function is using what
2015-09-29T17:05:09 < Viper168> I loved your games Ecco
2015-09-29T17:05:10 < Ecco> and also figure out exactly when the max stack usage is reached
2015-09-29T17:05:44 < mtbg> Bundestrojaner: and how does SetSysClock set the clock? it always enables pll and sets your frequency regarding SystemCoreClock variable?
2015-09-29T17:05:59 < mtbg> or it takes into account something other or else?
2015-09-29T17:11:44 < Viper168> I guess the fame has gotten to his head
2015-09-29T17:11:55 < Viper168> not even dolphins are immune
2015-09-29T17:12:15 < Viper168> I heard flipper was a rapist too
2015-09-29T17:12:22 < Bundestrojaner> mtbg: as far as i understand, it sets the pll always to 6*8MHz, waits for pll to work, sets pll as clock source and waits again till system runs on pll
2015-09-29T17:12:22 < Bundestrojaner> http://paste.ubuntu.com/12612602/
2015-09-29T17:16:17 < aadamson> I'm not sure what platform you are working with/on, but if using and STM32 that isn't all wrapped up in the CUBE crap.  There is an AppNote for each and an excel spreadsheet that is a clock tool
2015-09-29T17:16:39 < aadamson> it generates the systemxxx.c file for the specific processor based upon how you want your clock(s) setup
2015-09-29T17:16:48 < aadamson> e.g (let me see if I can find an example)
2015-09-29T17:16:58 < dongs> that looks like F103 stuff
2015-09-29T17:17:04 < dongs> you dont need excel for that shit
2015-09-29T17:17:08 < dongs> its like 3 lines of actual code
2015-09-29T17:17:11 < dongs> if you dont want error checking
2015-09-29T17:17:17 < aadamson> here's the one for the F4 - http://www.st.com/web/catalog/tools/FM147/CL1794/SC961/SS1533/PF257927
2015-09-29T17:17:22 < aadamson> and dongs is also correct
2015-09-29T17:17:49 < aadamson> but you *can't* just use the systemxxx.c file that was included with the environment that you are using, who knows how it's configured for the clock
2015-09-29T17:18:22 < aadamson> Well, I suppose you can *if* you want whatever it was setup with
2015-09-29T17:19:02 < mtbg>  /* If HSE fails to start-up, the application will have wrong clock  configuration. User can add here some code to deal with this error */
2015-09-29T17:19:20 < mtbg> wonderful piece of code, that lets user handle errors
2015-09-29T17:19:25 < aadamson> if this is by chance the gnueclipse plugin, then you set a define for the crystal speed and it's systemxxx.c file will assume the fastest speed possible I believe
2015-09-29T17:19:26 < dongs> ya thats copypaste from f103 system.c
2015-09-29T17:19:28 < mtbg> by digging into its files
2015-09-29T17:19:40 < mtbg> and finding right place reading the comments
2015-09-29T17:20:29 < aadamson> anyway, this aint arduino land (thank heavens) and something the programmer needs to deal with (and probably should)
2015-09-29T17:20:39 < Bundestrojaner> aadamson: yes, i use the gnu arm eclipse-plugins
2015-09-29T17:21:09 < aadamson> Bundestrojaner, so do I, but I always handle the clock stuff myself either via a clock tool, or making the changes as needed
2015-09-29T17:21:23 < mtbg> Bundestrojaner: do you have external crystal oscillator?
2015-09-29T17:22:01 < Bundestrojaner> mtbg: i use the stm32f0-discovery board. as far as i know, it has a 8MHz crystal
2015-09-29T17:22:09 < mtbg> ok
2015-09-29T17:22:25 < aadamson> Bundestrojaner, I think you need to go read the docs, it does not
2015-09-29T17:22:45 < aadamson> and it has a number of internal clocking options or external ones.  The schematic for all the discovery boards are available
2015-09-29T17:22:59 < aadamson> I just finished an application with the f051 so I've been through all of this

2015-09-29T17:23:37 < zyp> the stm32f0 discovery doesn't have a crystal, but OSC_IN is fed by an 8mhz signal from the onboard st-link, which is equivalent to having an 8mhz crystal

2015-09-29T17:24:36 < zyp> see how?
2015-09-29T17:24:44 < zyp> the st-link has an 8mhz crystal
2015-09-29T17:24:55 < Bundestrojaner> by looking at the pcb
2015-09-29T17:25:16 < Bundestrojaner> it's between stlink and the arm
2015-09-29T17:25:33 < karlp> I can see dead people, but it doesn't mean they're real.
2015-09-29T17:26:06 < aadamson> hehe... "stlink and the arm"... that would be f103 and the f051 - both arms ... to nit pick... in jest
2015-09-29T17:26:17 < decimad> https://github.com/decimad/stmlib/blob/master/stmlib/rcc/pll_parameters.hpp you can also do those calcs with a full search during compile time ;)
2015-09-29T17:27:02 < aadamson> anyway, the f051 is pretty flexible, and it will run by default with no external osc attached, so it's kinda important that whatever clock you think you have, you really have - configured.
2015-09-29T17:27:03 < karlp> yeah, if you'd rather save 20 bytes of flash in exchange for 10000 lines of c++ template magic goop

2015-09-29T17:29:00 < decimad> also this isn't about saving space or anything, the constants will be as small... it's about having to start an external tool or not
2015-09-29T17:29:42 < aadamson> decimad, but that's the whole point, you don't need too, it's only a hand ful of registers that need to be diddled
2015-09-29T17:29:46 < aadamson> to do what you want
2015-09-29T17:30:07 < decimad> what do I want?
2015-09-29T17:30:45 < aadamson> I haven't a clue - thankfully, but most will want to enable a clock, pll, etc and on the f1's, it's only a handful lines of code to do that
2015-09-29T17:31:48 < karlp> aadamson: you're not going to win having a lengthy chat with him, he's pretty deeply committed to constexpr templating all the things :)
2015-09-29T17:32:19 < decimad> yeah, with the constexpr it's one line and you don't need to calc the constants (and you don't need to comment them, because all whats in the code is src clock and dest clock)
2015-09-29T17:32:19 < aadamson> hehe... not about to try, I can barely hold my head above water with cpp anyway :0
2015-09-29T17:33:06 < karlp> one line... heh, links to 100s of lines of goop to set the pll :)
2015-09-29T17:33:25 < decimad> those hundreds of lines are the calculation
2015-09-29T17:33:27 < aadamson> https://dl.dropboxusercontent.com/u/6730484/ScreenClip.png - may latest science experiment - let's see how many switching supplies you can cram in the physical size of an AA battery :)...
2015-09-29T17:33:41 < aadamson> oh and the f051.
2015-09-29T17:33:43 < decimad> and it does a full search... something you would have to do in non-trivial cases
2015-09-29T17:33:50 < aadamson> but just a fun toy for now...
2015-09-29T17:35:01 < karlp> nice break off programming tab, cute
2015-09-29T17:35:30 < aadamson> hehe... PITA is what it si actually...
2015-09-29T17:35:32 < karlp> I like how it leaves them on the pins there.
2015-09-29T17:35:45 < karlp> what's the problem with it?
2015-09-29T17:35:57 < aadamson> made panelizing a bit of a PITA
2015-09-29T17:36:10 < karlp> yeah, was thinking panelling would be a downside :)
2015-09-29T17:36:19 < zyp> I don't like the idea of automatically calculating the PLL parameters, it obscures some of the complexity that you should be aware of
2015-09-29T17:36:20 < karlp> should put it beside the antenna protrosion
2015-09-29T17:36:40 < aadamson> one of those had I moved it forward or back you could flip one and dovetail, but nope not on this rev
2015-09-29T17:36:48 < aadamson> yeah, karlp, I'll move it at some point
2015-09-29T17:37:12 < zyp> like the fact that sysclk have to be a multiple of 24 if you want to be able to generate 48mhz for usb
2015-09-29T17:37:43 < decimad> zyp: that's all static assertable
2015-09-29T17:39:07 < upgrdman_> any statistic pros in here? i have a stupid homework problem that i simulated but the results surprise me. not sure how to solve the problem mathematically. if you have six dice, and roll them, on average how many rolls would be needed to see at least once di be a six? from sim'ing, i get 1.49 rolls on average.
2015-09-29T17:40:26 < Bundestrojaner> once di be a six? you mean at least one dice is a 6?
2015-09-29T17:40:43 < upgrdman_> ya
2015-09-29T17:41:10 < decimad> (5/6)^6  are the odds to not hit a 6 :)
2015-09-29T17:41:53 < decimad> 1 - (5/6)^6 are the odds to hit at least one six
2015-09-29T17:42:00 < mtbg> (5/6)^n
2015-09-29T17:42:02 < upgrdman_> which is 0.6651
2015-09-29T17:42:05 < mtbg> in n rolls
2015-09-29T17:42:13 < Bundestrojaner> the prob for a six is 1/6 per dice or 5/6 to be something else. so 1-(5/6)^6
2015-09-29T17:42:50 < zyp> 1/(1-(5/6)^6) is around 1.50
2015-09-29T17:43:04 < upgrdman_> yay my sim is right :)
2015-09-29T17:43:35 < upgrdman_> now the weird part: part 2: roll 18 dice, how many rolls on average needed to see at least 3 dice come up as sixes.
2015-09-29T17:43:40 < upgrdman_> i got 1.67
2015-09-29T17:43:45 < upgrdman_> shouldn
2015-09-29T17:43:53 < upgrdman_> shouldn't it be the same 1.5
2015-09-29T17:44:45 < zyp> no

2015-09-29T17:49:55 < decimad> hrmm, I think I could only do that with (2 over 18) * 5^16 + (1 over 18) * 5^17 + (0 over 18) * 5^18 so I'd need huge numbers
2015-09-29T17:51:19 < decimad> what's the short answer? :)

2015-09-29T17:52:47 < decimad> so that'd mean 1 - 6^18 / ( the term I stated )
2015-09-29T17:52:57 < decimad> erm
2015-09-29T17:53:00 < decimad> the other way around
2015-09-29T17:53:17 < decimad> (the term I stated / 6^18)
2015-09-29T17:53:31 < decimad> let's see
2015-09-29T17:58:40 < decimad> yeah, it's the simple binomial case, right? ;)
2015-09-29T17:59:23 < fenugrec> https://en.wikipedia.org/wiki/Binomial_distribution
2015-09-29T18:00:36 < zyp> oh, right, you're subtracting the probability of 2, 1, or 0
2015-09-29T18:01:49 < decimad> 1/6 success, then we need that we have less or equal to 2 successes... so binomial distribution of 0, 1, 2 (that's actually what I wrote up there, but I wasn't aware of the distribution anymore), sum them up and you have the anti-event
2015-09-29T18:02:11 < zyp> yeah

2015-09-29T18:13:57 < rewolff> I played "find-the-chip" yesterday..... Found it... http://prive.bitwizard.nl/stm32f030f.jpg
2015-09-29T18:14:36 < rewolff> The STM32F030F processor is NOT in the center of its package....
2015-09-29T18:14:41 < zyp> more like find the die
2015-09-29T18:14:49 < rewolff> :-)
2015-09-29T18:14:54 < Ecco> weird
2015-09-29T18:14:54 < zyp> laser cut?
2015-09-29T18:14:58 < Ecco> why?
2015-09-29T18:14:59 < rewolff> Yep.
2015-09-29T18:15:05 < Ecco> what package is that BTW?
2015-09-29T18:15:07 < rewolff> For fun. :-)
2015-09-29T18:15:09 < rewolff> TSOP20.
2015-09-29T18:15:11 < Ecco> ok
2015-09-29T18:15:23 < Ecco> so like 5mmx5mm?
2015-09-29T18:15:40 < chris_99> going to use a microscope on it?
2015-09-29T18:16:22 < zyp> uh, looks like you're mostly going to see residue from the package if you try that
2015-09-29T18:16:22 < rewolff> I think we still have some gunk on most of the die's we tried.
2015-09-29T18:16:35 < zyp> yeah
2015-09-29T18:16:45 < Ecco> maybe acetone can clean that shit?
2015-09-29T18:16:49 < rewolff> So next time we'll do a few more passes.
2015-09-29T18:16:54 < rewolff> I tried IPA.
2015-09-29T18:17:00 < zyp> burn the die as well? :)
2015-09-29T18:17:06 < rewolff> i.e. this is with IPA cleaning.
2015-09-29T18:17:39 < rewolff> We tried to laser-cut PCBs. The 35 micro-meter copper doesn't give a F*** how much you laser it.
2015-09-29T18:18:02 < rewolff> It dissipates the heat too quickly to parts not-currently-under-laser-fire.
2015-09-29T18:18:46 < zyp> haha
2015-09-29T18:19:03 < rewolff> It seems the actual die behaves the same. This makes lasering the black stuff that directly contacts the die a bit harder....
2015-09-29T18:19:21 < chris_99> acetone probably won't work alas
2015-09-29T18:19:22 < zyp> and even if you could burn through it, you'll instantly vaporize the fiberglass behind it
2015-09-29T18:19:40 < mtbg> try dimethylformamide
2015-09-29T18:19:42 < rewolff> The guy on hackaday had most of the bonding wires intact before cleaning. Our attemts fried those bonding wires pretty good.....
2015-09-29T18:20:12 < Sync> rewolff: depends on the power your lazor has
2015-09-29T18:20:16 < Sync> but yeah the copper is an issue
2015-09-29T18:21:56 < rewolff> Re Copper PCB lasering: Yeah, we found that as well. Cuts nicely (NOT!) through the PCB, while leaving the copper completely alone.... So to laser just the copper we'd have to make it vaporize the copper and then stop at exactly the right moment before it ruins the fibreglass. Not doable. Project scrapped. Worth a try though.

2015-09-29T18:26:41 < fenugrec> acetone will not attack anything metallic, and I suspect IC packaging plastic will just say "lol" when drowned in acetone
2015-09-29T18:26:58 < Ecco> ok :)

2015-09-29T18:32:00 < rewolff> Didn't you expect the die to be in the middle of the package? I did. The attiny44 is in the middle of the package.
2015-09-29T18:32:05 < fenugrec> I'm assuming you already know what the IC does ? So many other things you could be reverse-engineering instead p-)
2015-09-29T18:32:35 < rewolff> The FT232R is only slightly asymmetric.
2015-09-29T18:33:30 < rewolff> (but maybe its a fake....) (I don't think I have enough die visible to do the compares with the die fotos of the fake vs real ones yet).

2015-09-29T19:10:28 < jon1012> decimad, why ?
2015-09-29T19:12:20 < decimad> Because it had so many quirks at the low level of circuit data structures. It was invented before stl containers and smart pointers it seems
2015-09-29T19:13:02 < decimad> on top of those coding issues came the I_WANT_NO_NAMESPACE_ITEM class naming

2015-09-29T19:16:52 < jon1012> decimad, oh yeah

2015-09-29T19:17:36 < decimad> yeah, that one was nice, I used it too... besides a few crashes... but I could live with it
2015-09-29T19:17:36 < jon1012> decimad, they were implementing features one by one if I recall well, so I guess it's a rewrite
2015-09-29T19:18:32 < fenugrec> kicad will become seriously interesting when they get around to full sch<->pcb fwd/back annotation
2015-09-29T19:18:48 < fenugrec> with pin/gate swapping, etc.
2015-09-29T19:19:17 < jon1012> fenugrec, I only used eagle and geda before, so those aren't missing for me
2015-09-29T19:19:25 < decimad> with reasonable data structures this seems doable... except those ambiguous corner cases which are bound to happen
2015-09-29T19:19:59 < fenugrec> eagle does it... the problem (IIRC) was transferring, without races, changes between 2 processes
2015-09-29T19:20:17 < jon1012> fenugrec, well, only from sch to brd no the other way around
2015-09-29T19:20:33 < jon1012> fenugrec, and when you do, it just erases traces and places new components
2015-09-29T19:20:41 < jon1012> fenugrec, on kicad, if you reload netlist it does the same
2015-09-29T19:20:47 < fenugrec> eagle is all single-process so it's "easy". In Eagle you can pinswap from the brd view no ?
2015-09-29T19:20:48 < decimad> What I was wondering, is it normal that schematic traces are 'drawn' instead of a real connected graph?

2015-09-29T19:24:00 < decimad> But since I dont come from the pcb area, I had expected this stuff work like "normal" software. Like, you click a net, and then you can move it... you click a corner, then you can move the point, etc...
2015-09-29T19:24:24 < fenugrec> jon1012 I had doubts for a second, but in Eagle 5 you can pinswap in the BRD, and the SCH will follow. That's back-annotation, and can be extra super useful
2015-09-29T19:24:35 < jon1012> fenugrec, never used it
2015-09-29T19:24:58 < decimad> oh, I'm talkin eeschema here... the router was okay
2015-09-29T19:25:00 < fenugrec> jon1012 what about re-numbering parts inside a PCB view ? Not sure kicad can do that
2015-09-29T19:25:15 < fenugrec> i.e. R12 <-> R394874
2015-09-29T19:25:33 < jon1012> fenugrec, each time I tried to change something in pcb view I got "please do it in schematic view" message
2015-09-29T19:25:44 < decimad> when I last looked, eeschema and pcbnew didnt know anything about each other
2015-09-29T19:25:50 < decimad> the data was transferred over a file format
2015-09-29T19:25:52 < fenugrec> (jon1012 gate-swap is also precious when you have a bunch of quad op-amps and a tight layout, and not 8 layers to play with  p-)
2015-09-29T19:25:55 < jon1012> fenugrec, and when I tried harder got "anottation has been severed" crap
2015-09-29T19:25:57 < fenugrec> hehe, there you go
2015-09-29T19:26:26 < decimad> and pcbnew would cache the data and could update it from a new input file
2015-09-29T19:26:36 < fenugrec> So yeah, I'm not using kicad yet.
2015-09-29T19:28:05 < fenugrec> (For me the move VS drag thing was "obvious" because it's the same in LTSpice p-))
2015-09-29T19:28:46 < Bundestrojaner> mtbg: i have found the usart-problem (and the explanation why all timers work): USART_Init calls RCC_GetClocksFreq(&RCC_ClocksStatus);, which returns 288MHz for System_CLK and (more important) USART2_CLK...
2015-09-29T19:28:46 < Bundestrojaner> 48*6=288 -> baudrate = 19200/6
2015-09-29T19:32:28 < Fleck> zyp: http://imgur.com/lIHDVJV :D I need more power :D I can't just push it out
2015-09-29T19:33:05 < Fleck> that cap is messed up now :D used screwdriver :p
2015-09-29T19:33:38 < mtbg> Bundestrojaner: ok, so then you were supposed to set that variable to your crystal frequency?
2015-09-29T19:34:01 < Fleck> they could just sell them like that, not put together :/

2015-09-29T20:33:08 < Bundestrojaner> i thought the systemclk is wrong
2015-09-29T20:34:01 < aadamson> nope, sorry, should have mentioned it was *that* define... just set it to the main osc freq... if on a discovery just set it to 8mhz then
2015-09-29T20:34:08 < aadamson> the build process will take care of the rest.
2015-09-29T20:34:52 < aadamson> *I* didn't like all the *old std perip* and cmsis, etc, so I upgraded mine all to the latest after the fact and when I did that, I updated the systemxxx.c file with a clock tool built version
2015-09-29T20:36:19 < aadamson> but it's *NOT* straigh forward in how you do that, you can't just copy over the later files (well you can, but you'll end up with some built errors depending on what you have your warnings set too, - I prefer pretty strong ones)

2015-09-29T20:41:58 < aadamson> I suppose that really an FPU related issue for the processors, but fyi... you can look up single-precision-constant for specifics
2015-09-29T20:43:11 < Bundestrojaner> aadamson: how is that floating-point-related?
2015-09-29T20:43:45 < aadamson> Well, it's supposed to be defined in the project->properties->c/c++ general->paths and symbols->symbols tab

2015-09-29T20:46:01 < aadamson> not sure if that covers the newer *big arms*, I've not messed with them
2015-09-29T20:47:38 < aadamson> Bundestrojaner, btw, with that !defined in the .h file, you could actually *remove* that system define in the project properties if you are only going to be messing with the 8mhz disocovery clock setup (and any other defines that you've added)
2015-09-29T20:48:11 < aadamson> btw, putting in in main.h, you then have to make sure that it's precidence is correct or some files may miss it... better to put that in the commandline like it was intended

2015-09-30T01:23:52 < upgrdman_> anyone here familiar with induction heaters? the pro ones let you adjust the frequency, while hobby ones are usually a ZVS setup to make it gentler on the FETs. for variable frequency setups, do they just PWM the gate open-loop and accept the inductive spikes? its not like they can change the parallel capacitance, so im not sure how else they might do it.
2015-09-30T01:27:06 < Sync> they are simply driving it hard
2015-09-30T01:27:17 < Sync> but most high power units actively track resonance
2015-09-30T01:27:26 < Sync> as you can push moar power there

2015-09-30T02:23:02 < BFreeze> I agree with flyback. High current inductive loads are typically FETs.
2015-09-30T02:23:25 < BFreeze> Ooops
2015-09-30T02:23:27 < BFreeze> lol
2015-09-30T02:23:36 < BFreeze> Yeah, IGBTs.
2015-09-30T02:23:58 < BFreeze> Hybrid electric vehicles and full-electric vehicles use IGBTs. I have a small inductive cooktop I took apart; It uses IGBTs, too.
2015-09-30T02:24:55 < GargantuaSauce> i think the intent is to supply it with low voltage dc
2015-09-30T02:25:07 < Laurenceb__> flyback is here
2015-09-30T02:25:07 < GargantuaSauce> which IGBTs are not particularly suitable to switch

2015-09-30T02:40:51 < Sync> flyback: that's not really true
2015-09-30T02:41:00 < Sync> modern mosfets are usually more efficient at higher voltages

2015-09-30T03:32:27 < zyp> Sync, depends
2015-09-30T03:32:37 < Sync> sure
2015-09-30T03:32:48 < Sync> but in my experience they are
2015-09-30T03:32:58 < Sync> especially in resonant apps
2015-09-30T03:33:11 < Sync> hardswitching it is so-so
2015-09-30T03:34:54 < zyp> for high voltages, IGBTs tends to have lower on-state resistance than FETs but FETs tend to be faster, so frequency is an important part of the equation
2015-09-30T03:35:32 < Sync> igbts do not have a on resistance
2015-09-30T03:35:40 < Sync> they have a voltage drop at saturation
2015-09-30T03:35:58 < Sync> so I*Usat vs I²*Rdson
2015-09-30T03:36:03 < Sync> + dynamic losses

2015-09-30T03:36:31 < zyp> doesn't have to be linear to be a resistance
2015-09-30T03:36:59 < zyp> or constant for that matter
2015-09-30T03:37:20 < Sync> sure but it is unusual to describe it as a resistance
2015-09-30T03:37:24 < zyp> the voltage drop isn't strictly constant with varying current anyway
2015-09-30T03:37:46 < Sync> the saturation voltage stays pretty much the same
2015-09-30T03:39:26 < Sync> it increases with current, of course but for most purposes it is fine to say it stays the same
2015-09-30T03:39:33 < Sync> or rather for comparison purposes

2015-09-30T03:40:17 < zyp> my point still stands, the on state voltage drop and hence dissipated power tends to be lower
2015-09-30T03:44:47 < Sync> ok, lets compare FGH60N60SMD vs IPW65R019C7
2015-09-30T03:45:00 < Sync> the igbt says 1.9V Uds at 60A
2015-09-30T03:45:32 < Sync> which is 114W, the fet says 19mOhm at 25°C junction temp, thus 68W
2015-09-30T03:46:43 < zyp> that's a pretty small IGBT
2015-09-30T03:47:19 < Sync> both are used in similar applications
2015-09-30T03:47:26 < Sync> which is why I'm comparing them
2015-09-30T03:47:45 < Sync> if we are going for big tractive apps igbts are better as there are not a lot of mosfet bricks
2015-09-30T03:48:18 < Sync> although up to 20-40kW I'm seeing more and more fets
2015-09-30T03:50:14 < fenugrec> I doubt the jct will stay at 25C very long @ 68W p-)
2015-09-30T03:50:29 < zyp> was about to remark on that
2015-09-30T03:50:34 < Sync> sure
2015-09-30T03:51:20 < Sync> but if you look at the high temp spec they come out exactly even
2015-09-30T03:52:15 < Sync> the game has changed in the last years in favor of fets, although igbts also have gotten better dynamically
2015-09-30T03:53:17 < fenugrec> interesting
2015-09-30T03:54:25 < Sync> and you can decrease overall system losses by throwing fets at it because they parallel and decrease resistance
2015-09-30T03:54:30 < Sync> which igbts cannot
2015-09-30T03:54:57 < zyp> looking at the high temp spec I see 144W, that's higher than 126W for the FET
2015-09-30T03:56:07 < dongs> sup dongs

2015-09-30T03:56:50 < dongs> they will deliver it by zano
2015-09-30T03:57:29 < Sync> I was looking at the graph below and used 35mOhm
2015-09-30T03:57:38 < Sync> but yeah, still
2015-09-30T03:58:30 < zyp> what happens if you look at twice that voltage?
2015-09-30T03:58:44 < Sync> 1200V?
2015-09-30T03:59:01 < Sync> well, then it shifts to igbts again
2015-09-30T04:00:13 < Sync> but you see my point, for most off-line applications fets are very good candidates

2015-09-30T06:02:31 < dongs> so do the opposiute of how youre enabling it
2015-09-30T06:02:35 < dongs> god damn man, is this so difficul
2015-09-30T06:02:37 < dongs> t
2015-09-30T06:02:58 < upgrdman> NVIC_EnableIRQ(EXTI0_1_IRQn); // irq for pins 0,1

2015-09-30T06:03:13 < dongs> nice link bro
2015-09-30T06:03:25 < dongs> upgrdman: surely disabling it in EXTI would make 1000x more sense
2015-09-30T06:03:27 < upgrdman> ColdKeyboard, and correspondign Disable function too
2015-09-30T06:03:33 < ColdKeyboard> upgrdman: Thanks! :)
2015-09-30T06:04:11 < upgrdman> dongs, oh ya. doh.
2015-09-30T06:04:15 < upgrdman> ColdKeyboard, look into SYSCFG->EXTICR
2015-09-30T06:04:24 < upgrdman> its probably the better way than what i just mentioned

2015-09-30T09:15:34 < dongs> Really sorry to all the lucky preorder customers that have received their Zano's but, I still can't believe they are getting Zano's before backers. Did we back this project so that preorders would get theirs first, would we have backed Zano if we knew that preorders would ship first?
2015-09-30T09:15:39 < dongs> I think not! TG has made a huge and unforgivable mistake by doing this. And as an even bigger slap in the face, early backers in the UK have had to watch later preorders receive their Zano's, I mean come on, at least ship to backers in each region first. This has become ridiculous!
2015-09-30T09:16:27 < Getty> so there are people with a zano?
2015-09-30T09:16:33 < Getty> that is actually far more surprising
2015-09-30T09:16:34 < dongs> like 3
2015-09-30T09:16:39 < aandrew> I was going to say the same
2015-09-30T09:16:43 < dongs> but there's no app to fly it

2015-09-30T09:17:14 < Getty> dongs: everything you say about zano makes no sense.....
2015-09-30T09:17:55 < Getty> so 3 people have it, cant fly it, and the others are complaining cause those 3 actually preordered and.... they.... dont complain? show off... nothing? i dont get it

2015-09-30T09:20:03 < dongs> well, thats where 2.3mil came from
2015-09-30T09:20:11 < Getty> yeah but its there, done
2015-09-30T09:20:13 < Getty> there will not be more
2015-09-30T09:20:16 < dongs> right
2015-09-30T09:20:29 < Getty> and there will be no turn back (or at least, that would be anyway holocaust)
2015-09-30T09:20:49 < Getty> i dont think just some bad reviews could bring down the kickstarter
2015-09-30T09:20:58 < Getty> does kickstarter at all has a payback strategy?!?!
2015-09-30T09:21:06 < dongs> no but
2015-09-30T09:21:20 < dongs> for 2.3gbp in EU, there is bound to be some class - action like thing
2015-09-30T09:21:37 < jpa-> more likely the theory that preorders have a bit of customer protection (and perhaps within credit card claim period), while backers are screwed already
2015-09-30T09:21:39 < dongs> also, dickstarter is "public" forum
2015-09-30T09:21:49 < dongs> people searchin zano -> go to dickstarter -> click preorder button
2015-09-30T09:21:55 < dongs> they go read comments

2015-09-30T09:24:13 < Getty> mh they probably backed a lot themself
2015-09-30T09:24:31 < Getty> like taking half the base investment money they might have gathered from the bank to bake themself
2015-09-30T09:24:53 < Getty> i mean.... most of the time i was reading the comments and was just wondering how much passion someone can give for someone who has proven nothing of competence

2015-09-30T09:25:04 < dongs> right
2015-09-30T09:25:12 < dongs> the cock-stroking
2015-09-30T09:25:43 < Getty> i mean, that is even more stupid as the apple loving... there at least is some "preproduct" where you can say "it will be that quality again, i like that quality"
2015-09-30T09:25:56 < Getty> but there..... what the hell are they cheering for? why can people be so illusioned?
2015-09-30T09:26:44 < Roklobsta> they got zano religion.
2015-09-30T09:27:10 < Getty> we already call the apple stuff religion, that with zano is more like a cult
2015-09-30T09:27:24 < Getty> and at some point they all drink poison
2015-09-30T09:27:41 < Roklobsta> coz when you die you get 72 zanos
2015-09-30T09:27:46 < Getty> hahahhahahahaaha
2015-09-30T09:28:06 < Getty> now it all makes sense
2015-09-30T09:28:21 < dongs> The Zano's ability to stop in mid-air and hold its position and then return to home at the tap of a button is really impressive ... or would have been had they shown that. Instead I see a drone that is LESS capable than the $50 toy on my desk. I have a very bad feeling about this.

2015-09-30T13:21:17 < Sync> sounds reasonable
2015-09-30T13:21:47 < Bundestrojaner> can i work with intentional overflows or will they cause any problems because the HW knows it's an overflow?
2015-09-30T13:21:47 < Bundestrojaner> i want to use an array (256 Bytes) as ringbuffer. my indices (beginning and length) are both uint8_t.
2015-09-30T13:21:47 < Bundestrojaner> new data is inserted at array[beginning+length]. So if beginning is at 250 and length is 30, the next byte is written to array[25]
2015-09-30T13:22:35 < qyx_> this probably won't work
2015-09-30T13:25:42 < Bundestrojaner> what's the best way to make it work? beginning as uint16_t and insert data at array[(beginning+length)&0x00FF]?
2015-09-30T13:30:21 < dongs> qyx, why wouldnt it
2015-09-30T13:30:23 < dongs> itll work just fine
2015-09-30T13:33:21 < Bundestrojaner> thx, I asked because this buffer is driven by usart- and i2c-interrupts and debugging this would be crap...
2015-09-30T13:33:21 < Bundestrojaner> but i forgot i need a 16bit-index anyway because my i2c-flash doesn't support sequential write
2015-09-30T13:34:10 < karlp> get better debugging.
2015-09-30T13:34:14 < karlp> trace for the win.
2015-09-30T13:34:33 < karlp> also wat, how does not supporting sequential write relate to your indices?

2015-09-30T13:36:18 < jpa-> Bundestrojaner: remember that C quite often automatically casts calculations to 'int' type, i.e. 32 bits
2015-09-30T13:36:40 < jpa-> so using (beginning+length)&0xFF is safer, and the compiler will optimize the & operation just fine
2015-09-30T13:36:55 < Bundestrojaner> jpa-: thx
2015-09-30T13:41:04 < Bundestrojaner> karlp: because it doesn't support sequential write, i have to tell it every time where it should write to.
2015-09-30T13:41:04 < Bundestrojaner> i have a 16bit-index now. this index is increased everytime by one when a byte is succesfully written to the i2c-flash and never decreased.
2015-09-30T13:41:04 < Bundestrojaner> so beginning is the adress for the i2c-flash to write to. beginning&0x00FF is the index to read from the ringbuffer. and (beginning + length)&0x00FF is the index to write to the ringbuffer

2015-09-30T14:27:05 < decimad> also consider using (beginning+length) % size because it expresses intent
2015-09-30T14:27:25 < rewolff> Bundestrojaner: If you do uint_8 pos = beginning + length;  .... array[pos] ... that should work. (the array[beginning+length] will possibly be upgraded to ints before doing the array indexing, as said before. )
2015-09-30T14:27:49 < rewolff> but I agree with ZYP: Write: #define BUFBITS 8
2015-09-30T14:27:58 < rewolff> #define BUFSIZE (1<<BUFBITS)
2015-09-30T14:28:09 < rewolff> #define BUFMASK (BUFSIZE - 1)
2015-09-30T14:28:23 < rewolff> and then mask with BUFMASK...
2015-09-30T14:28:30 < decimad> Is that defined to be workable for buffbits = 32?
2015-09-30T14:28:43 < rewolff> Sure!
2015-09-30T14:28:47 < Bundestrojaner> why not just &0x00FF?
2015-09-30T14:29:11 < decimad> so c actually defines max+1-1 to equal max?
2015-09-30T14:29:16 < rewolff> But not on STM32 as it would be difficult to define the buffer to be 4G and be able to address it....
2015-09-30T14:30:50 < decimad> I'd really think that int(1)<<32 is undefined
2015-09-30T14:30:52 < rewolff> decimad: Oh. the overflow at 32bit ints I didn't thing about that. Sorry. But anyway, 32 bits is not reasonable. It was meant for bufbits  between say 4 and 10.
2015-09-30T14:31:02 < decimad> yeah...
2015-09-30T14:32:18 < rewolff> Writing it with the bufbits being the only "changeable" define, makes things clear and will optimize with a byte move if you define it to 8...
2015-09-30T14:33:45 < karlp> I'd use % and let the compiler sort it out.
2015-09-30T14:33:50 < rewolff> Bundestrojaner: if your level of programming expertise is such that you prefer & 0xff  over & BUFMASK, then go ahead and do it that way. I find the latter preferable.
2015-09-30T14:38:59 < zyp> I'd probably prefer & myself if I wanted to be certain to not invoke a division/modulo operation on hardware without fast division
2015-09-30T14:39:24 < zyp> and then just a static assert on size to ensure it's a power of 2
2015-09-30T14:40:54 < zyp> i.e. static_assert(size & (size - 1) == 0, "Size must be a power of 2.");

2015-09-30T14:42:59 < mtbg> it can still invoke if one's circular buffer is handled by some generic functions which take size from buffer structure or argument
2015-09-30T14:43:05 < karlp> as longa s you like telling people to think about how big a buffer they need in terms of the number of bits it has
2015-09-30T14:43:17 < zyp> that's silly
2015-09-30T14:43:20 < karlp> % will always work, jsut you'll get less performance if you choose a "bad" buffer size.

2015-09-30T15:31:17 < Ecco> the core prevents you from shooting yourself in the foot ("key" on reset for example)
2015-09-30T15:31:23 < Ecco> but you can shoot yourself in the hand just fine
2015-09-30T15:31:39 < Tectu> lolwut?
2015-09-30T15:31:50 < Tectu> just go the last two lines, but wtf, what a comparasion :D
2015-09-30T15:32:32 < Ecco> :-D
2015-09-30T15:32:53 < Ecco> We were talking about how you need to write a certain pattern to some Cortex M4 registers for the rest of the write to be accepted
2015-09-30T15:32:58 < zyp> rewolff, not really
2015-09-30T15:33:07 < Ecco> that seems like a good idea, but I was wondering *why* it was present only on certain parts
2015-09-30T15:33:35 < zyp> you can just do if(index >= size) { index -= size; } instead of index = 0
2015-09-30T15:33:41 < Ecco> The way I see it is that either it's a good idea so do it everywhere, either it's not so stop doing it :)

2015-09-30T16:04:11 < Ecco> well
2015-09-30T16:04:20 < Ecco> Not sure if that'd be a good thing
2015-09-30T16:04:25 < Ecco> I mean, with such little RAM
2015-09-30T16:04:56 < Ecco> I'm much more concerned by the increased RAM usage (pointers 2x as big) than by the gain in processing power
2015-09-30T16:05:51 < zyp> you could have 64-bit working registers but keep a 32-bit address space
2015-09-30T16:06:18 < zyp> 64-bit address space doesn't really make sense on a platform without MMU and kilobytes of memory
2015-09-30T16:09:19 < Ecco> indeed
2015-09-30T16:09:30 < Ecco> Wouldn't that trigger a bunch of weird bugs though?
2015-09-30T16:09:47 < zyp> why?
2015-09-30T16:09:49 < Ecco> I mean, in general, 64-bit machines use 64-bit pointers
2015-09-30T16:10:23 < zyp> avr has 8-bit registers and 16-bit pointers
2015-09-30T16:10:25 < Ecco> (so if some code detects a 64bit processor and assumes pointers will be 64-bits long -> bug)
2015-09-30T16:10:29 < Ecco> hmm, ok :)
2015-09-30T16:10:31 < zyp> there's no fixed relation between those
2015-09-30T16:10:45 < Ecco> indeed
2015-09-30T16:10:54 < zyp> that's a bad assumption to make
2015-09-30T16:10:59 < zyp> this is why intptr_t exists
2015-09-30T16:11:19 < Ecco> yeah but not sure everyone's using it
2015-09-30T16:11:46 < zyp> not my fault you're writing shitty code
2015-09-30T16:12:43 < Ecco> not your fault

2015-09-30T16:53:43 < rewolff> RE: "It looks like the hardware is not fully reset" Your LCD is not reset by writing to SYSRESETREQ. So apparently your code works when the LCD comes up from "powerup" but not when it has already been initialized.

2015-09-30T17:51:02 < dongs> The registration process will be open in the next 24 hours. We are testing, testing testing internally, on loads of devices, lots of Zano's and trying to make sure we have everything covered.
2015-09-30T17:51:06 < dongs> When you first go to fly. I'd suggest either a nice large room free of objects (3m * 3m) is a nice area if your not used to Zano or ideally outside on a grass oval. Gives you a great chance to put Zano through its paces without risk of hitting something.
2015-09-30T17:51:33 < dongs> aandrew: they have a video of it cutting some stubble

2015-09-30T17:52:48 < aandrew> that what it looks like
2015-09-30T17:52:55 < aandrew> they call it a "fiber" that the laser runs within
2015-09-30T17:53:06 < jon1012> they cut it with that hot wire
2015-09-30T17:53:19 < dongs>  Japan uses 920MHz which is a software retune of the 915MHz unit. So the white for UK/EU is an 868MHz unit, the others are 915MHz and I think there is also a software retune of the 868MHz for where I can not recall at this moment.

2015-09-30T17:53:23 < dongs> All these variations of Zano's have their data encoded into the serial number programmed into Zano. This is so the operating system can identify the hardware and correctly configure it for the relevant region.
2015-09-30T17:53:41 < dongs> so amaze
2015-09-30T17:53:45 < aandrew> they are smart to go after the other ISM bands, 2.4G is shit

2015-09-30T20:41:16 < ReadError> do they make any specific diodes for logic level stuff
2015-09-30T20:41:32 < ReadError> something that has a very low voltage drop and just stops a signal from traversing back?
2015-09-30T20:42:41 < ReadError> or hm CMOS is unidirectional, maybe some device there i could use
2015-09-30T20:43:41 < fenugrec> ReadError  schottky not good enough ?
2015-09-30T20:44:17 < ReadError> it might be, im just wondering if there is a 'best practice' or some kind of goto for stuff like this
2015-09-30T20:44:39 < fenugrec> what "signal" could "traverse back" ?
2015-09-30T20:45:04 < ReadError> basically, I have 2 stm32 pins going to one pin
2015-09-30T20:45:29 < ReadError> there is a case which the '1' pin may need to TX to the stm32 usart RX
2015-09-30T20:46:05 < ReadError> but another case in which another device will be transmitting (and the '1' pin would be in input capture for timer on another stm32 pin)
2015-09-30T20:46:37 < ReadError> so im trying to prevent the $otherdevice TX from feeding back to the pin
2015-09-30T20:48:39 < fenugrec> You probably want a "wire-or" configuration, i.e. have the pins pulled-up (idle level=1), and the TX pins are configured as "active low" ... if the "otherdevice" supports that
2015-09-30T20:49:23 < ReadError> hmm yea I didnt think about the pwm output hitting the serial pin

2015-09-30T20:49:30 < ReadError> day*
2015-09-30T20:49:49 < ReadError> guess I need a mux and a GPIO
2015-09-30T20:49:52 < fenugrec> what are you doing with PWM and serial data on the same bus p-))
2015-09-30T20:50:27 < ReadError> good quesiton, im not sure why this is being done

2015-09-30T21:35:26 < kakimir> good
2015-09-30T21:36:18 < zyp> are you the finnish guy in the news with the KKK getup? is that why you've been busy?
2015-09-30T21:37:53 < Steffanx> that was jpa-
2015-09-30T21:37:55 < kakimir> I wish I had such sense of occasion
2015-09-30T21:39:19 < kakimir> does my english make sense
2015-09-30T21:39:47 < Steffanx> if it google translates it makes sense
