2015-02-01T00:00:09 < kakeman> where I live 40cm is quite common
2015-02-01T00:00:49 < kakeman> but if I go up the hill there is more like 70cm or more
2015-02-01T00:02:48 < kakeman> you have to have humid air and around 0 celsius temperature to have a lot of snow
2015-02-01T00:04:24 < kakeman> big flakes pouring
2015-02-01T00:06:23 < qyx_> yep, we had yesterday
2015-02-01T00:06:38 < kakeman> scandic mountains causes snow to fall before air from atlantic ocean comes here
2015-02-01T00:06:43 < qyx_> 20cm of new snow, traffic collapsed
2015-02-01T00:07:09 < qyx_> they are not used to have that much here
2015-02-01T00:07:49 < kakeman> still it happens every year or so
2015-02-01T00:08:09 < Fleck> http://fleck.rullz.lv/skatcam/viewcam.php?cam=4 << wet here :( minimal snow left
2015-02-01T00:08:37 < qyx_> same here, everything melts
2015-02-01T00:09:01 < kakeman> thats why I don't want to live south
2015-02-01T00:09:25 < qyx_> huh
2015-02-01T00:09:26 < Roklobsta> it never snows here.  thank christ.
2015-02-01T00:09:31 < qyx_> your green light is more like blue
2015-02-01T00:09:50 < Fleck> qyx_: nah, it's just in camera :D
2015-02-01T00:10:11 < Roklobsta> no snow means i don't have endless hours of time to hack stm32 because it's too cold outside.
2015-02-01T00:12:58 < kakeman> https://drive.google.com/file/d/0B2GcdpJiNGfKZUtyakp4eTlnWHc/view?usp=sharing taking trail snow mobile to off trail
2015-02-01T00:13:14 < Fleck> ;p
2015-02-01T00:13:38 < kakeman> best thing about winter and cold is unlimited hack time
2015-02-01T00:14:44 < kakeman> and not having anything that would distract me
2015-02-01T00:16:17 < kakeman> living in place where neighbours house is a dot of light in a horizon

2015-02-01T00:33:44 < kakeman> Steffanx: "real finnish" and "iceman" are such titles that I don't think I deserve.. yet
2015-02-01T00:34:15 < kakeman> there have not been ladies in this area for a decade I think

2015-02-01T00:35:41 < kakeman> when you add "real" to it things become mythological
2015-02-01T00:37:14 < kakeman> it's like saying you are a unicorn

2015-02-01T03:15:06 < Roklobsta> GargantuaSauce: how about all the embedded systems like adsl modems and firewalls or other linux based applicances that will never get updated?
2015-02-01T03:15:36 < GargantuaSauce> i think that is negligent
2015-02-01T03:15:51 < GargantuaSauce> it really irks me that my docsis modem has closed firmware that i can't update
2015-02-01T03:16:36 < Roklobsta> i use mikrotik routers.  they have updates for their whole range of devices every few weeks, so this libc bug won't affect them for long.
2015-02-01T03:16:44 < Roklobsta> that said, the user has to do an update too.
2015-02-01T03:17:04 < GargantuaSauce> if they really do keep it up to date, the issue was fixed months ago

2015-02-01T06:53:04 < upgrdman> those nippers looks like common cheap flush cutters. they're using better metal though, right? or are the nz-10's just disposable stuff with pretty handles?

2015-02-01T08:14:54 < PeterM> why not just use rfid tag as rfid tag
2015-02-01T08:15:46 < dongs> ...
2015-02-01T08:16:16 < dekar> it's powered from AC via clamping diodes

2015-02-01T08:17:43 < dongs> retarded
2015-02-01T08:17:53 < dongs> this is the kinda shit that makes it on hackaday
2015-02-01T08:18:19 < Roklobsta> it was on hackaday i am sure it's been on there
2015-02-01T08:18:50 < Roklobsta> it's macgyver RFID
2015-02-01T08:19:10 < dekar> I am amazed by the simplicity, I don't really care about how useful it is
2015-02-01T08:19:23 < dongs> Unfortunetly(for me) I do believe Torquing group changed there mind and is now going to be providing a cheap charger with zano. hexacharger is a great option for charging your batteries. 6 batteries at a time. Designed for safety and to maximize the life expectancy of the batteries. It also is smart enough to not charge your batteries until they are at a safe temperature. It can be powered from the included wall outlet or any usb power supply like zano fuel.
2015-02-01T08:19:25 < dekar> wouldn't want to touch AVR anyway

2015-02-01T09:04:41 < dongs> nope,i just went back and checked theres only for F0/L0
2015-02-01T09:05:01 < dongs> those are just direct register dickigns w/o stdlib or cube, so i guess they did it for low/small flash versions only
2015-02-01T09:07:49 < emeb_mac> why can't atmel sell amazingly cheap and useful demo boards like the Discovery series?
2015-02-01T09:08:01 < dongs> or make MCUs that arent shit
2015-02-01T09:08:07 < emeb_mac> that
2015-02-01T09:08:24 < dongs> i mean even shit like sama5 has ADC silicon straight out of Atmega series
2015-02-01T09:08:28 < dongs> which means useless slow 10bit garbage
2015-02-01T09:08:38 < dongs> and peripherals in general suck
2015-02-01T09:09:40 < dongs> people use that shit?
2015-02-01T09:09:42 < dongs> are they $10-15?
2015-02-01T09:09:49 < dongs> last i checked sama5xplained was like $100

2015-02-01T09:12:09 < dongs> All in all, I (still) find the AK240 to be the most consistent performer I.ve ever encountered in the digital audio player space . it just has this absolutely amazing top-to-bottom cohesiveness. Using it as my yard stick and comparing it to the 6x times less expensive Pono, I heard a more natural and extended top end. Cymbals lingered a bit longer in their brassy decays. Bass had more punch, more texture. The mid-range had better 3-D sound-staging.
2015-02-01T09:14:26 < emeb_mac> dongs: pono is such a POS
2015-02-01T09:15:01 < emeb_mac> R2COM: sounds like you should be using atmel stuff

2015-02-01T12:30:56 < dongs> FSUSB43
2015-02-01T12:31:33 < Tectu> exactly what I need!!
2015-02-01T12:31:35 < dongs> yep
2015-02-01T12:31:48 < Tectu> that package... really?
2015-02-01T12:31:57 < dongs> pfft
2015-02-01T12:32:06 < Tectu> any alternatives?
2015-02-01T12:32:13 < dongs> i've shipped something like 5k units wiht that and had zero issues soldering
2015-02-01T12:32:22 < dongs> well, anything "usb switch" is gonna be kinda small, especialyl for hs-usb
2015-02-01T12:32:31 < dongs> cuz you have differential pairs that are like very close together
2015-02-01T12:32:39 < dongs> i dont think youre gonna find one in tssop style thing

2015-02-01T12:32:54 < dongs> you could just use a random DPDT analog switch and make sure it has enough bandwidth..

2015-02-01T12:34:19 < Tectu> dongs, you soldered them manually?
2015-02-01T12:34:26 < qyx_> 5k units?
2015-02-01T12:34:37 < dongs> Tectu: of course not
2015-02-01T12:34:49 < dongs> qyx_: as in products including that switch IC
2015-02-01T12:34:49 < Tectu> that's why I ask... "I had zero issues with soldering" -> of course not if an assembly house does that for you
2015-02-01T12:34:53 < Tectu> I just need a few, dongs :P
2015-02-01T12:35:10 < dongs> tectu, paste + reflow works fine
2015-02-01T12:35:15 < Tectu> dongs, does your product do what I want?
2015-02-01T12:35:50 < dongs> unlikely, it was just keeping USB off on a device that was 12V-powered to make sure it wouldn't enumerate
2015-02-01T12:35:59 < Tectu> okay
2015-02-01T12:36:07 < Tectu> well, that chip is just perfect. Thank you dongs
2015-02-01T12:36:08 < dongs> there was no MCU so I couldn't do 1.5V pullup stuff based on vinput
2015-02-01T12:37:50 < Tectu> dongs, some other question: I have a set of speakers with build in amp connected to a laptop dockingstation using casual 3.5mm jack. When the laptop is unplugged or just shut down, the speakers give a really annoying and loud noise from them (coming from the dockingstation which is just fucked up, any other device works just fine)
2015-02-01T12:37:58 < Tectu> I assume that they forgot to somehow ground the audio signal if disabled
2015-02-01T12:38:01 < Tectu> how easy to fix?
2015-02-01T12:39:11 < dongs> not sure, I dont do analog :)
2015-02-01T12:39:47 < Tectu> dongs, about that USB stuff... I just realize that I should have mentioned that I have two devices that need to be switched
2015-02-01T12:39:59 < Tectu> dongs, are there easy-to-use USB hub things out there that I can put in front of that switch?
2015-02-01T12:40:01 < dongs> 1:2?
2015-02-01T12:40:18 < dongs> you could, USB hubs are dead easy
2015-02-01T12:40:25 < dongs> i duno if youre g onna find a 2 port on tho
2015-02-01T12:40:35 < dongs> digikey has some 4port stuff in lqfp48-ish
2015-02-01T12:40:35 < Tectu> I don't mind a 4 or 8 port either :)
2015-02-01T12:40:44 < Tectu> is there no issue with PCB layouting due to high frequency stuff?!
2015-02-01T12:40:47 < dongs> they just need power + decoupling caps
2015-02-01T12:40:57 < dongs> well, you could do it on 4layer if you really want but...
2015-02-01T12:41:54 < Tectu> dongs, so I can take that 4 port hub and put it's "output" (1ch side) directly on that FSUSB42 switch to have a USB hub with 4 device slots and 2 host ports and a stupid push button?
2015-02-01T12:41:58 < dongs> i have also done highspeed hub on 2l and didnt bother impedance matching shit etc and it worked fien
2015-02-01T12:42:51 < dongs> so 2 upstream ports -> FSUSB -> single port -> hub -> 4 ports
2015-02-01T12:42:59 < dongs> yes, it works either way (bidirectional)
2015-02-01T12:43:22 < Tectu> yeap, that i want
2015-02-01T12:43:30 < Tectu> do you have a link to such a 4 port hub that you can recommend?

2015-02-01T13:20:44 < dongs> sup
2015-02-01T13:20:50 < KreAture_> playing around as usual
2015-02-01T13:20:51 < KreAture_> :)
2015-02-01T13:20:51 < dongs> R2COM: i am not into skill surfing
2015-02-01T13:21:11 < KreAture_> dongs I got my new displays from buydisplay.com and the packaging was superb
2015-02-01T13:21:17 < dongs> KreAture_: cool
2015-02-01T13:21:23 < KreAture_> dongs so now I just need to play with em!
2015-02-01T13:21:40 < KreAture_> making a board for the neato to replace the original button/display board
2015-02-01T13:22:10 < dongs> http://www.digikey.com/product-detail/en/USB2514BI-AEZG/USB2514BI-AEZG-ND/2258528 for 4 ports
2015-02-01T13:23:13 < KreAture_> dongs I am making two versions of the board.  First simply replaces the original display with a easily available one using a FPC tail. The other goes a step further and adds color display, a intermediate mcu to translate data, a connector to loop the lidar via the displayboard and options to do overlay of radardata on the display etc.
2015-02-01T13:23:22 < KreAture_> first one "fixes it"
2015-02-01T13:23:29 < KreAture_> second one ubers it
2015-02-01T13:23:32 < KreAture_> :)
2015-02-01T13:23:34 < KreAture_> nerd out :)
2015-02-01T13:24:34 < dongs> plot radar data, get a visit from three-letter agency
2015-02-01T13:24:50 < Tectu> thank you dongs
2015-02-01T13:24:55 < KreAture_> hehe the lidar on the neato is the most exciting feature it has
2015-02-01T13:25:05 < KreAture_> being able to look at that data is a popular request
2015-02-01T13:25:20 < KreAture_> oh and I am putting a bluetooth if in there too, so I can send the data wirelessly
2015-02-01T13:27:20 < KreAture_> Neato Robotics vacuum cleaner
2015-02-01T13:27:22 < KreAture_> :)
2015-02-01T13:27:28 < KreAture_> it uses lidar
2015-02-01T13:27:35 < KreAture_> and SLAM
2015-02-01T13:27:44 < KreAture_> (Simultaneous Location And Mapping)
2015-02-01T13:28:08 < dongs> basically
2015-02-01T13:29:28 < KreAture_> the difference is the way it operates and cleans
2015-02-01T13:29:34 < KreAture_> aka nothing like a rumba
2015-02-01T13:29:49 < KreAture_> https://www.youtube.com/watch?v=hf1zY8vRC2E
2015-02-01T13:31:34 < KreAture_> about the same as the high end rumbas
2015-02-01T13:31:52 < KreAture_> a lot of robot entusiasts buy it just to rip the lidar module out of it
2015-02-01T13:31:57 < KreAture_> 4-600 usd
2015-02-01T13:32:03 < KreAture_> depending on model
2015-02-01T13:32:48 < KreAture_> I don't think you get it
2015-02-01T13:33:08 < KreAture_> you as a person would have no issue cleaning the room quickly with even a $50 vac
2015-02-01T13:33:18 -!- Guest78708 is now known as RaYmAn
2015-02-01T13:33:21 < KreAture_> no corners gonna be shit
2015-02-01T13:33:28 < KreAture_> room gonna be nice
2015-02-01T13:33:39 < KreAture_> because it has scheduling and such and cleans while I am away
2015-02-01T13:33:46 < KreAture_> it's not mine
2015-02-01T13:33:52 < KreAture_> I know
2015-02-01T13:34:00 < KreAture_> but it does my entire home every day
2015-02-01T13:34:10 < KreAture_> when I am not home
2015-02-01T13:34:26 < KreAture_> so I don't have to listen to it or have vacuum noises when I want to watch scifi
2015-02-01T13:35:07 < KreAture_> what i found was there was very little dust accumulating in corners since most of the dust comes from other areas of room, and is blown or shuved into corners
2015-02-01T13:35:36 < KreAture_> so I can take the corners every once in a while manually, and there is far less dust there than if it did not do rest of room so often
2015-02-01T13:35:47 < KreAture_> anyway, it's a geek thing
2015-02-01T13:36:00 < KreAture_> I would much rather have a robot clean my house badly than do it myself
2015-02-01T13:36:09 < KreAture_> well I got money to waste so why not ?
2015-02-01T13:36:13 < KreAture_> It makes me happy
2015-02-01T13:36:49 < KreAture_> I bought $150 worth of displays last week, for playing with micros on, because I liked them, not because I needed em
2015-02-01T13:37:07 < KreAture_> ppl seem to disagree, based on ho wmany buy these
2015-02-01T13:38:23 < PeterM> KreAture_, yall niggers postin in a troll convo
2015-02-01T13:38:50 < KreAture_> lol

2015-02-01T13:44:12 < KreAture_> PeterM I think the best part of the neato is the pet-hair roller since i have pets and thus need to clean more often

2015-02-01T14:38:48 < zyp> you don't even need qt, matplotlib is nice enough for stuff like that
2015-02-01T14:40:12 < zyp> you could probably even write a gdb plugin that invokes matplotlib to extract and graph data with a single command

2015-02-01T16:32:32 < Tectu> any photographers in here?
2015-02-01T16:36:34 < qyx_> i occasionaly use my 2mpix sony ericsson mobile camera
2015-02-01T16:54:10 < Tectu> so is focal length basically the "level of zoom"?
2015-02-01T16:55:46 < kakeman> yes
2015-02-01T16:56:05 < dongs> fecal length
2015-02-01T17:01:59 < Tectu> dongs, how important is length matching on USB DP/DN lines?
2015-02-01T17:02:11 < dongs> so-so
2015-02-01T17:02:14 < dongs> it has worked for me
2015-02-01T17:02:20 < dongs> but it is recommended.
2015-02-01T17:02:21 < Tectu> dongs, I took a look at that digikey hub thing and they didn't even bother to put the pins next to each other. they have them "around the corner"
2015-02-01T17:02:54 < dongs> heh
2015-02-01T17:04:00 < qyx_> have you seen this? http://imgur.com/a/v6bjC
2015-02-01T17:04:01 < Tectu> dongs, do I bother about external crystal or will the internal do just fine?
2015-02-01T17:04:03 < qyx_> it still works
2015-02-01T17:04:09 < dongs> Tectu: for wat, stm32?
2015-02-01T17:04:42 < Tectu> qyx_, those cables are not even shielded...?
2015-02-01T17:04:45 < Tectu> dongs, for that USB2412 thig
2015-02-01T17:05:15 < dongs> Tectu: i havent specifically used that one, two models of usb hubs I used (genesyslogic and alcor) both required crystals.
2015-02-01T17:05:20 < dongs> usually you need 12M xtal
2015-02-01T17:05:54 < Tectu> On-chip 24 MHz crystal driver or external 24 MHz
2015-02-01T17:05:54 < Tectu> clock input
2015-02-01T17:06:01 < Tectu> on-chip crystal?!
2015-02-01T17:06:03 < dongs> 'driver'
2015-02-01T17:06:06 < dongs> still needs crystal
2015-02-01T17:06:12 < Tectu> aaah
2015-02-01T17:06:14 < dongs> dickhead, look at reference design or something
2015-02-01T17:06:17 < Tectu> it's just the tarduino style
2015-02-01T17:06:17 < Tectu> yeah

2015-02-01T17:09:55 < Tectu> dongs, even in a sane package
2015-02-01T17:10:03 < dongs> thats too big
2015-02-01T17:10:09 < dongs> 48lqfp can have 4 port easily
2015-02-01T17:10:21 < dongs> that one probably has individual port leds and shit
2015-02-01T17:10:35 < kakeman> nope Tectu
2015-02-01T17:11:45 < dongs> bedtime
2015-02-01T17:12:44 < Tectu> dongs, show better alternative.
2015-02-01T17:13:34 < qyx_> you can use that fe1.1s
2015-02-01T17:13:37 < qyx_> or whatever
2015-02-01T17:14:00 < Tectu> "that"?
2015-02-01T17:14:04 < dongs> Tectu: digikey parametric search for usb hub in 48qfp.
2015-02-01T17:14:06 < dongs> really sleepign now.
2015-02-01T17:14:09 < qyx_> available on alibaba in 1000000+ quantities
2015-02-01T17:14:28 < qyx_> Tectu: the same as i pasted on the picture
2015-02-01T17:14:40 < Tectu> ah
2015-02-01T17:14:54 < Tectu> qyx_, are those pictures from you?
2015-02-01T17:14:58 < Tectu> qyx_, who on earth buys such a thing
2015-02-01T17:15:54 < qyx_> me until i saw whats inside
2015-02-01T17:16:27 < qyx_> and if "such thing" means a hub with downstream ports on a cables - i like this
2015-02-01T17:16:39 < Tectu> my 70€ industrial 7-port switch feels good compared to that
2015-02-01T17:16:59 < qyx_> this was 6€

2015-02-01T18:44:42 < TheSeven> hm, I have an SD card that is apparently getting confused by sitting on a shared SPI bus
2015-02-01T18:45:01 < TheSeven> (the bus is shared between the SD card and an LCD)
2015-02-01T18:45:14 < TheSeven> I initialize the SD card first, then the LCD
2015-02-01T18:45:29 < TheSeven> after that, the SD card still seems to work
2015-02-01T18:45:43 < TheSeven> then I send some more pixels to the LCD, and the SD card will stop responding

2015-02-01T18:45:56 < TheSeven> reinitializing the SD card seems to bring it back, but only once
2015-02-01T18:46:44 < TheSeven> after sending some more pixels, and attempting to reinitialize the SD card again, it stops responding altogether (MISO stays high during CMD0)
2015-02-01T18:47:06 < TheSeven> however resetting the controller (f030), it pops back to life
2015-02-01T18:47:28 < TheSeven> now what the hell does rebooting the controller do that reinitializing the card doesn't...
2015-02-01T18:48:11 < TheSeven> I guess quite a bunch of I/Os will get tristated during that briefly, however SCK/MISO/MOSI/CS are the only pins that are connected between the controller and the card
2015-02-01T18:51:14 < jpa-> TheSeven: are you doing anything funny to the SPI peripheral, like changing clock speed, clock phase or clock polarity bits?
2015-02-01T18:52:01 < TheSeven> hm, only the speed if anything... (while everything is deselected and no transfers are running)
2015-02-01T18:52:41 < jpa-> the spi peripheral must be disabled before touching those bits (IIRC ref manual mentions this)
2015-02-01T18:52:47 < jpa-> otherwise it will generate extra bits on resume
2015-02-01T18:52:48 < TheSeven> and I'm giving the SD card an extra 0xff byte after deselecting to make it actually release the bus (although that wouldn't even be strictly required in this setup)
2015-02-01T18:53:16 < TheSeven> hm, even if it would generate extra bits I can't quite explain this behavior that way
2015-02-01T18:53:33 < jpa-> i have successfully had SD card and lcd touchscreen on same SPI bus, but I had to do something funny when switching between them
2015-02-01T18:53:52 < TheSeven> and it only happens with one particular type of cards, so I guess it's a card-side bug (that it gets confused in the first place)
2015-02-01T18:53:54 < jpa-> got a logic analyzer?
2015-02-01T18:54:34 < TheSeven> yes, a crappy bus pirate or the DSO ;) but this thing is only running at 1MHz core clock, so both should work :)
2015-02-01T18:55:28 < jpa-> yeah :)
2015-02-01T18:55:52 < jpa-> (do i remember wrong or was there some minimum clock below which SD cards don't work?

2015-02-01T19:04:08 < TheSeven> so far I didn't have trouble halting the clock for seconds while debugging in the middle of SD transactions

2015-02-01T19:10:46  * TheSeven spots glitches on MOSI...
2015-02-01T19:11:16 < TheSeven> does the SPI controller tristate MOSI between bytes?

2015-02-01T19:20:27 < TheSeven> not quite sure what those weird MOSI edges between bytes are
2015-02-01T19:21:04 < jpa-> looks normal enough
2015-02-01T19:22:08 < jpa-> your code is just not filling the SPI buffer fast enough so it goes to idle
2015-02-01T19:22:24 < TheSeven> during the response phase the glitches are inverted: http://i.imgur.com/S6Il9c2.png
2015-02-01T19:23:57 < TheSeven> so this is what the (failing) CMD0 looks like: http://i.imgur.com/dO4Neew.png
2015-02-01T19:25:21 < jpa-> if you look at ref man, MOSI is supposed to go high when there is no transmission going on

2015-02-02T00:24:58 < PaulFertser> With serial output, leds etc.
2015-02-02T00:25:07 < Fleck> right? :)
2015-02-02T00:25:09 < PaulFertser> You can write a gdb stub for it ;)
2015-02-02T00:25:19 < PaulFertser> There's stm8 flasher afaik.
2015-02-02T00:25:19 < karlp> kakeman: if you ask me during work hours, I can give you a gdb pything script that will plot an array as zyp suggested
2015-02-02T00:26:57 < Fleck> PaulFertser: yes. there is sdcc and stm8flash, works great, ok, will use old good way - UART ;D
2015-02-02T00:30:26 < kakeman> python=?
2015-02-02T00:31:19 < kakeman> just got 1536000 out of uart and will now see how far it will go
2015-02-02T00:31:40 < kakeman> wont do 2000000
2015-02-02T00:32:14 < Fleck> PaulFertser: btw, there is also SDCDB
2015-02-02T00:32:18 < karlp> https://github.com/afaerber/stlink works for stm8, not sure whether he has debugging though, but I presume so
2015-02-02T00:33:46 < kakeman> can it be that sendin a char would need around ~40-48 clock cycles?
2015-02-02T00:33:51 < kakeman> for uart
2015-02-02T00:34:51 < upgrdman> depends on baud rate, no?

2015-02-02T00:41:53 < kakeman> what actually limits uart maximum when clock is 72Mhz?
2015-02-02T00:42:34 < kakeman> maybe just fraction divider of uart doesn't get right enough
2015-02-02T00:43:50 < kakeman> but using speeds like 5MBps sounds just too much
2015-02-02T00:46:24 < kakeman> can't see it with reasonable effort before getting new debugger
2015-02-02T00:51:53 < upgrdman> anyone here worked with Resesas RX62 microcontrollers?
2015-02-02T00:52:14 < upgrdman> can firmware be read off of them, or do they support locking/fuses?
2015-02-02T01:01:22 < kakeman> https://code.google.com/p/blue-machines/source/browse/trunk/resources/docs/mcu/lpc2000.uart.baudrate.calculator.xls?spec=svn10&r=10 nice uart calculation tool for 550 based uarts

2015-02-02T02:18:47 < dongs> zyp, i have a 4L 0.4mm board im submitting
2015-02-02T02:19:01 < zyp> when?
2015-02-02T02:19:03 < dongs> (probably not something you'd want anyway
2015-02-02T02:19:05 < dongs> tomrorow
2015-02-02T02:19:13 < dongs> it is 0.4mm thick
2015-02-02T02:19:30 < zyp> that sounds pretty thin
2015-02-02T02:19:36 < dongs> indeedy
2015-02-02T02:19:40 < dongs> that cf>sata thing
2015-02-02T02:19:52 < dongs> i got mega lazy a nd no time so i will route it on 4L for laziness
2015-02-02T02:19:58 < zyp> oh, right
2015-02-02T02:20:03 < zyp> what's that for?
2015-02-02T02:20:18 < dongs> apparently sticking SSDs into shitty canon cams to save $ on CF cards
2015-02-02T02:20:34 < zyp> so CF slave and sata master?
2015-02-02T02:20:39 < qyx_> huh
2015-02-02T02:20:41 < zyp> which chip does that?
2015-02-02T02:20:45 < dongs> zyp, several
2015-02-02T02:20:50 < qyx_> will the ssd be hanging outside?
2015-02-02T02:20:52 < dongs> they're also: pin compatible
2015-02-02T02:20:53 < dongs> qyx_: yeah
2015-02-02T02:20:54 < qyx_> ductaped?
2015-02-02T02:20:55 < dongs> basically
2015-02-02T02:20:58 < dongs> off a FPC
2015-02-02T02:21:01 < zyp> I guess plain PATA-SATA bridge chips?
2015-02-02T02:21:04 < dongs> zyp: yep
2015-02-02T02:21:22 < dongs> there's  3 , jmicron, marvell (*waht im using), and sunspot or something chink company
2015-02-02T02:21:27 < dongs> they have identical pinout
2015-02-02T02:21:35 < dongs> its like tehy cloned each other
2015-02-02T02:21:36 < qyx_> and does the canon support ata mode?
2015-02-02T02:21:40 < zyp> heh, that standardized
2015-02-02T02:21:53 < qyx_> iirc only one mode was obligatory
2015-02-02T02:22:15 < dongs> qyx, you can stick shit like microdrives in there, i would presume thats ata only ,but who knows
2015-02-02T02:22:19 < dongs> so i get to make it and find out
2015-02-02T02:25:31 < KreAture_> zypedidoodaa zypedy hey!
2015-02-02T02:26:27 < KreAture_> dongs there are a few marvel chipsets for sata/pata and sata/usb with bugs I think.  We had one at work that failed at a specific temperature.
2015-02-02T02:26:34 < zyp> KreAture_, sup?
2015-02-02T02:26:39 < KreAture_> It worked abowe and below but not at this exact temp
2015-02-02T02:26:49 < KreAture_> zyp still making pcb's for the vacuum
2015-02-02T02:26:50 < KreAture_> :)
2015-02-02T02:27:14 < zyp> I feel there's a «they suck» joke there somewhere
2015-02-02T02:27:27 < KreAture_> oh yes
2015-02-02T02:27:47 < KreAture_> and the more they suck, the more people want to blow their heard erned cash on em

2015-02-02T02:40:57 < dongs> I can possibly make better for you. Starting tomorrow I will be offering a free shell for zano for anyone that buys a hexacharger and 4 batteries.
2015-02-02T02:41:05 < dongs> every one of this guys posts is advertising his fucking scamshop
2015-02-02T02:41:08 < dongs> on zano forum
2015-02-02T02:41:28 < dongs> hes gonna be refunding all those orders
2015-02-02T02:41:44 < dongs> when people end up with shit chink batteries they have no use for
2015-02-02T02:42:20 < dongs> KreAture_: theres only one for pata/sata, and a shitload of devices used them (mostly old mobos before sata  was in southbridge, like atom-based shite).
2015-02-02T02:42:52 < KreAture_> well then
2015-02-02T02:43:06 < KreAture_> I just remember a project at work where they refused to accept the error untill we proved it
2015-02-02T02:43:07 < dongs> but if you can give me 88SA8052 docs I'll take them - i'm basing my schema only on a couple laptop reference designs :)
2015-02-02T02:43:21 < KreAture_> They they were like "just make sure to let it heat up over that point and then reset it"
2015-02-02T02:43:47 < dongs> you need to make a OCUSBSATA (oven controlled usbsata)
2015-02-02T02:43:55 < dongs> and have a 10 minute warmup time
2015-02-02T02:44:00 < KreAture_> really annoying as it turned out our proper design was the issue, a crappy cooling design made it work
2015-02-02T02:44:01 < KreAture_> hehe
2015-02-02T02:46:17 < KreAture_> btw
2015-02-02T02:46:31 < KreAture_> seeedstudio now offers a 48 hrs expedited service at 20 bucks addon ?

2015-02-02T02:47:48 < KreAture_> They asked me if I was sure it was correct, and I answered yes
2015-02-02T02:47:49 < KreAture_> LOL
2015-02-02T02:47:57 < KreAture_> when I got the boards back I was like wtf!
2015-02-02T02:48:00 < KreAture_> My bad
2015-02-02T02:48:01 < KreAture_> lol
2015-02-02T02:48:18 < KreAture_> They looked good on screen though, untill you realize the pads are really solder mask
2015-02-02T02:48:24 < KreAture_> haha
2015-02-02T02:48:49 < KreAture_> looks like they can do my neato boards for $4
2015-02-02T02:48:51 < KreAture_> a piece
2015-02-02T02:48:54 < KreAture_> not bad for small run

2015-02-02T04:49:45 < dongs> hm 256k is still same footprint
2015-02-02T04:50:26 < PeterM> for sramdongs or foir eeprom
2015-02-02T04:50:27 < dongs> hmm or not
2015-02-02T04:50:30 < dongs> sram
2015-02-02T04:50:40 < dongs> its same SIZE but address lines are moved around
2015-02-02T04:51:15 < PeterM> put some 0 ohm resistors in for option
2015-02-02T04:51:25 < dongs> way too many changes
2015-02-02T04:51:31 < dongs> all ~14 address bits are in different places
2015-02-02T04:51:33 < dongs> laff
2015-02-02T04:51:38 < PeterM> owut
2015-02-02T04:51:41 < dongs> yeah 4 srs
2015-02-02T04:51:52 < dongs> http://media.digikey.com/pdf/Data%20Sheets/Cypress%20PDFs/CY62256N%20RevB.pdf vs CY6264
2015-02-02T04:51:55 < PeterM> usually its onl;y the first one or the last one
2015-02-02T04:52:12 < dongs> I/O is same but all Axx are fucking moved around
2015-02-02T04:53:17 < dongs> ISSI version of it is sane
2015-02-02T04:53:32 < dongs> it must be just cypress idiocy
2015-02-02T04:54:02 < dongs> ISSI has A14, A13 where 6264  has vcc and/or nc
2015-02-02T04:55:03 < PeterM> dongshowmuchtracesonbackofboard? surely you cpouldfit footprints for both onthere
2015-02-02T04:55:21 < PeterM> fuck i need a new keyboard
2015-02-02T04:56:01 < PeterM> dongs, how much traces are on the back of the board, surely you could fit both footprints on there
2015-02-02T04:56:16 < dongs> i think parts only go on top
2015-02-02T04:56:27 < PeterM> i know
2015-02-02T04:56:35 < dongs> yeah i could, but anyway, that cypress 256K was  some bullshit, nonstandard pinout
2015-02-02T04:56:41 < dongs> there are other 256k with same pinout
2015-02-02T04:58:36 < PeterM> oh, also, dongs, protip, make the gold edge connector as tall as you can, to allow for shitty cartridge moldings

2015-02-02T04:59:18 < dongs> it should be ok
2015-02-02T05:03:20 < PeterM> fair enough, usually i make it taller, so if the cart goes in to the connector, it still makes contact.

2015-02-02T06:08:55 < upgrdman> dongs, what do i search for on maps? that's the problem. theres not many elec stores that have a good selection
2015-02-02T06:09:10 < upgrdman> e.g. good luck if you want damn near ANYTHING smd
2015-02-02T06:09:11 < dongs> click the mic icon

2015-02-02T06:10:49 < dongs> you walk into this bullshit "electric town" and unless you want anniemay or used panties, the only shit you'll find is overpriced consumer goods or useless through-hole garbage
2015-02-02T06:10:54 < dongs> speaking of through-hole garbage
2015-02-02T06:11:05 < dongs> maybe zyp can take some pics of those elusive SMD reels he claims to have seen @ akihabara
2015-02-02T06:11:09 < dongs> since he has unlimited time and shit
2015-02-02T06:12:26 < englishman> maybe they were ws2812b reels. but not for dicknplace, already soldered like ready to go
2015-02-02T06:12:27 < upgrdman> a year or two ago i was looking for solder paste. i call like 10 electronics shops. NONE of them had it, and the half that thought they did also thought that "solder paste" is paste flux. idiots.
2015-02-02T06:12:43 < upgrdman> then a month later, i saw some lead free paste at frys
2015-02-02T06:12:52 < englishman> heh last walk in place didnt know either
2015-02-02T06:12:54 < upgrdman> from dickquick
2015-02-02T06:12:58 < englishman> they had some chipquick flux
2015-02-02T06:13:01 < dongs> upgrdman: stores shouldnt really carry solder paste
2015-02-02T06:13:07 < dongs> cuz it is perishable + needs proper storage.
2015-02-02T06:13:15 < dongs> in usa best overpriced place for amaze solder paste is zeph
2015-02-02T06:13:19 < dongs> zephtronics
2015-02-02T06:13:20 < upgrdman> ? i've had some in my desk for 1+ year, works ok
2015-02-02T06:13:29 < englishman> mine did but it was all dried out mechanix paste like on goodluckbuy for $3 but older
2015-02-02T06:13:33 < gxti> it's harder to kill than most people give it credit for
2015-02-02T06:13:44 < gxti> but i still wouldn't really trust it
2015-02-02T06:14:02 < dongs> upgrdman: you make home etched boards with 2.54mm pitch dips on them
2015-02-02T06:14:10 < dongs> a pile of shit will work to solder on that
2015-02-02T06:14:17 < dongs> try same paste on .4mm pitch stuff and see how it works

2015-02-02T06:14:55 < GargantuaSauce> well and there's also the distinction of one-offs vs mass production
2015-02-02T06:15:15 < dongs> yes, but zeph is good for oneoff too
2015-02-02T06:15:22 < dongs> its just expensive (but I think worth it for quality)
2015-02-02T06:15:41 < GargantuaSauce> if you're pretty much guaranteed to have to rework it for one reason or another anyway its not like you have to worry about the decrease in yield brought about by old paste
2015-02-02T06:20:13 < GargantuaSauce> okay so dumb question
2015-02-02T06:22:00 < PeterM> dumb answer
2015-02-02T06:22:24 < GargantuaSauce> if a cmos ic is rated for a particular supply voltage, would the limiting factor be the reverse breakdown of say the clamping diodes, or the maximum power dissipation of the package being exceeded by leakage through the actual complementary logic
2015-02-02T06:25:05 < PeterM> GargantuaSauce, depends on the IC, for say a cmos iverter, you'd probably cook the fets with shootthrough
2015-02-02T06:25:49 < GargantuaSauce> so it hits a point at which the gates are no longer driven high/low enough?
2015-02-02T06:26:22 < PeterM> no, it hits a point in the switching transition where the gates are bothon for too long
2015-02-02T06:26:31 < dongs> are you trying to power a 74 series with 120V AC
2015-02-02T06:27:28 < GargantuaSauce> sooo perhaps lower frequency operation at higher voltage might be ok?
2015-02-02T06:27:37 < GargantuaSauce> i should probably just fry a few figuring how far i can push it
2015-02-02T06:28:18 < PeterM> also ou want somenthignthat candrive them pretty hard
2015-02-02T06:28:28 < GargantuaSauce> just looking at whether i could maybe use hcf4051 to switch signals in my analog synth without redesigning it to run at a lower voltage everywhere
2015-02-02T06:28:40 < PeterM> you want your inputs to be 0-7v if your using the chipon 7v supply
2015-02-02T06:29:24 < GargantuaSauce> oh yeah certainly
2015-02-02T06:35:06 < dongs> GargantuaSauce: uh wat
2015-02-02T06:35:15 < dongs> hcf4051 is up to 18V?
2015-02-02T06:35:34 < GargantuaSauce> and my shit is running off +-15V
2015-02-02T06:35:42 < dongs> oh fun
2015-02-02T06:36:18 < GargantuaSauce> the design is a little bit on the antiquated side
2015-02-02T06:36:44 < GargantuaSauce> but to modernize would mean uh just using a single dsp for everything
2015-02-02T06:36:46 < GargantuaSauce> and that's booorrring

2015-02-02T07:27:56 < dongs> and they keep using that old version
2015-02-02T07:28:08 < dongs> yes
2015-02-02T07:28:13 < dongs> loool

2015-02-02T07:29:37 < englishman> lol what mobo is designed in usa
2015-02-02T07:29:43 < englishman> or gfx card
2015-02-02T07:30:24 < dongs> eagle
2015-02-02T07:30:28 < englishman> kikad
2015-02-02T07:30:42 < dongs> Did you know? Parrot designs their shit in eagle
2015-02-02T07:31:00 < dongs> yeah
2015-02-02T07:31:05 < dongs> and gay faggot dtv chips company
2015-02-02T07:31:20 < dongs> i duno about their uav trash but Dibcom that they bought used only eagle
2015-02-02T07:32:29 -!- TeknoJuce [~TeknoJuce@kodi/staff/TeknoJuce] has quit [Read error: Connection reset by peer]
2015-02-02T07:33:38 < dongs> sorry to hear that
2015-02-02T07:34:11 < dongs> but
2015-02-02T07:34:14 < dongs> i duno if it s very 'comples"
2015-02-02T07:34:17 < dongs> its FPGA
2015-02-02T07:34:21 < dongs> so they could pinswap anything they w  anted
2015-02-02T07:34:26 < dongs> it mostly looks like 1:1 connections to shit
2015-02-02T07:34:39 < dongs> you could probly even do that in eagle
2015-02-02T07:34:41 < dongs> without much effort
2015-02-02T07:34:54 < dongs> haha
2015-02-02T07:35:55 < dongs> ya so does altium
2015-02-02T07:35:59 < PeterM> cadance is garbage mentor > cadance
2015-02-02T07:36:46 < PeterM> none, just lookedat existing layuts
2015-02-02T07:36:56 < gxti> dongs: waveshare sells some "neo-6m compatible" modules, i wonder if they make them lol
2015-02-02T07:37:25 < PeterM> R2COM, what boards yopu done in PADS?
2015-02-02T07:38:05 < PeterM> i didnt mention altium
2015-02-02T07:39:29 < dongs> gxti: link? you mean using raw chipset + making their own metalshield and shit?
2015-02-02T07:39:54 < gxti> dunno, no details on webpage other than some .7z archive that was downloading at 2 bytes per year
2015-02-02T07:40:09 < dongs> link, ill ask my waveshit contact
2015-02-02T07:40:23 < gxti> http://www.wvshare.com/product/NEO-6M-C.htm
2015-02-02T07:40:47 < dongs> jebus that price
2015-02-02T07:40:49 < gxti> i'm not actually gonna buy it because i need more than just a basic whatever, just ran into it while shopping around and lol'd
2015-02-02T07:41:14 < gxti> i should look at the ublox chips though at some point, for all i know it's super cheap
2015-02-02T07:41:29 < dongs> eh, also super unobtanium
2015-02-02T07:41:34 < dongs> needz NDA +shit
2015-02-02T07:43:33 < gxti> boo
2015-02-02T07:44:30 < englishman> fisher pen or die
2015-02-02T07:46:47 < dongs> trolled out
2015-02-02T07:48:07 < PeterM> englishman, Fisher AG-7
2015-02-02T07:48:34 < englishman> thats my pen
2015-02-02T07:48:37 < englishman> how did you know
2015-02-02T07:49:02 < dongs> wao no errors
2015-02-02T07:49:36 < PeterM> i have a few of em too
2015-02-02T07:55:19 < dongs> wondering if I should bother breaking out any debug signasl
2015-02-02T07:55:23 < PeterM> although, for throw away pens, i quite like the papermate kilometrico - much smoother than bic crystals, they tent to runout quicker tho
2015-02-02T07:55:25 < dongs> if this shit is busted i think its just gonna be fucked
2015-02-02T07:56:02 < dongs> <PeterM> papermate has  a slightly rounded soundstage with heightened mid-range and smooth thick lines.
2015-02-02T07:56:58 < englishman> lol
2015-02-02T07:57:08 < englishman> fisher is only pen that doesnt suck
2015-02-02T07:57:16 < englishman> that is usually my metric for buying shit
2015-02-02T07:57:18 < englishman> that it doesnt suck
2015-02-02T07:58:16 < dongs> whats better SATADOGE or DOGESATA
2015-02-02T07:58:17 < dongs> im torn
2015-02-02T07:58:29 < englishman> such serial very ata

2015-02-02T08:07:38 < akaWolf> someone know, what is the function "__gnu_thumb1_case_uqi ?"
2015-02-02T08:07:44 < akaWolf> in GCC...
2015-02-02T08:09:37 < dongs> sounds like some shit they kept around for histerical reasons

2015-02-02T08:18:33 < PeterM> https://www.youtube.com/watch?v=eBDDOMfcx8I#t=64
2015-02-02T08:22:41 < dongs> loled
2015-02-02T08:23:55 < jpa-> akaWolf: sounds like switch-case decoding function for uint64_t
2015-02-02T08:24:49 < akaWolf> jpa-: why for uint64?
2015-02-02T08:25:00 < jpa-> uqi
2015-02-02T08:25:05 < jpa-> unsigned quad integer
2015-02-02T08:25:15 < akaWolf> ah ok
2015-02-02T08:25:36 < jpa-> better question is whether anyone uses thumb1 anymore
2015-02-02T08:25:57 < akaWolf> m0?
2015-02-02T08:26:16 < jpa-> umm, no?
2015-02-02T08:26:27 < jpa-> or yes?
2015-02-02T08:26:30 < jpa-> what do i know
2015-02-02T08:27:30 < dongs> thumb up butt
2015-02-02T08:27:36 < jpa-> i guess you can think of it "thumb1 plus a few extras" or "thumb2 minus a few instructions"
2015-02-02T08:28:19 < jpa-> wouldn't be surprised if that instruction gets used on thumb2 also, though
2015-02-02T08:28:23 < akaWolf> I dont know, why my known using thumb1 at Cortex M0
2015-02-02T08:28:37 < akaWolf> yeah, I think, that it's on thumb2
2015-02-02T08:30:38 < dongs> http://www.longs-motor.com/images/banner/banner_2.jpg shaft mode
2015-02-02T08:31:13 < akaWolf> jpa-: "The __gnu_thumb1_case_uqi is a helper which does an indexed jump on a densely packed switch table; quickly implements the switch."
2015-02-02T08:34:24 < PeterM> throug hole
2015-02-02T08:34:27 < PeterM> throug
2015-02-02T08:38:47 < akaWolf> jpa-: it's not a thumb2 proble, just cortex-m0 doesnt have tbb/tbh instructions anyway
2015-02-02T08:38:51 < akaWolf> m
2015-02-02T08:39:53 < akaWolf> so looks like it's just not correct function name
2015-02-02T08:40:45 < jpa-> i thought tbb/tbh are the new versions, an __gnu_thumb1_case_uqi is similar implemented in software
2015-02-02T08:41:00 < akaWolf> yeah
2015-02-02T08:41:53 < akaWolf> but dont know, why it named "__gnu_thumb1_case_uqi" and not just "__gnu_thumb_case_uqi"
2015-02-02T08:42:12 < jpa-> maybe because not useful for real thumb2?
2015-02-02T08:42:48 < akaWolf> maybe, I'm not so good in  specifications :)
2015-02-02T08:44:36 < akaWolf> looks like it so, yeah
2015-02-02T08:47:17 < PaulFertser> BTW, I've read an article yesterday showing how to use "phantom types" to get "strong typedef" functionality in C++. It seems quite usable.
2015-02-02T08:48:07 < akaWolf> C++11 already have strong typedef, not?
2015-02-02T08:48:39 < PaulFertser> Not that I know of.
2015-02-02T08:48:50 < PaulFertser> Boost has a macro for that.

2015-02-02T12:58:44 < Roklobsta> W10?  Really?
2015-02-02T12:59:57 < Roklobsta> don't worry, .net will choke it.
2015-02-02T13:02:17 < jpa-> choke it how?
2015-02-02T13:03:21 < Roklobsta> by running slow as a dog
2015-02-02T13:04:45 < jpa-> why?
2015-02-02T13:04:59 < jpa-> is the jit for arm worse than x86?
2015-02-02T13:07:46 < Roklobsta> i don't expect it to be stellar apart from toggling leds
2015-02-02T13:08:55 < jpa-> i would expect with windows running on arm tablets a while now that the JIT would be just fine
2015-02-02T13:09:06 < jpa-> .net on x86 is not that much slower than C on x86
2015-02-02T13:09:27 < jpa-> once you get to hand tuned optimization, C wins of course because it offers more control

2015-02-02T13:41:49 < Roklobsta> we'd just beat them harder until the PCB's looked OK.
2015-02-02T13:42:36 < Roklobsta> my last cad guy was the Human Autorouter.  A blur to watch.

2015-02-02T13:59:42 < dongs> oh
2015-02-02T13:59:43 < dongs> ok
2015-02-02T14:01:10 < dongs> Micro SD cards seem to be the way cameras are going. So I would have thought that this would be best for ZANO. It does look in the video, like a full size SD. What will my pledge of £159 get me, will it just be a cardboard shoe box?

2015-02-02T16:05:41 < Tectu> and that wasn't even high-roller class
2015-02-02T16:05:47 < Tectu> switzerland, yes
2015-02-02T16:06:07 < Tectu> 1'500 is pretty standard east european slut here
2015-02-02T16:06:10 < Tectu> (for one night)
2015-02-02T16:06:19 < Tectu> you don't get one hour below 300€

2015-02-02T16:07:01 < Tectu> a friend of mine who earns a shit load of money made a present to a friend. two really high roller ones for a night and it came out to 12k€

2015-02-02T16:14:18 < Tectu> kakeman, women are weird in general. no exception with swiss girls
2015-02-02T16:14:34 < Tectu> kakeman, anyway, as there are 50% forgein girls here I can give some good comparasion, I think:
2015-02-02T16:14:40 < jpa-> highly competent in messing up Tectu's head
2015-02-02T16:14:45 < qyx_> Tectu: pff we are driving mostly sane
2015-02-02T16:14:47 < Fleck> and yes, lines get redrawn in summer usually

2015-02-02T16:15:14 < Tectu> Fleck, huh?
2015-02-02T16:15:22 < kakeman> are swiss women beasts inside?
2015-02-02T16:15:23 < Tectu> Fleck, they draw lines here so they don't have to redraw them in 20 years
2015-02-02T16:15:29 < Tectu> kakeman, not at all. the oposite
2015-02-02T16:15:35 < Fleck> Tectu: not here :D

2015-02-02T16:15:49 < qyx_> cheap paint
2015-02-02T16:15:59 < Tectu> kakeman, they don't think that their pussys are made of gold like the eastern european girls (that i know - which are quite a lot)
2015-02-02T16:16:31 < Tectu> kakeman, they are usually quite focussed on success in their live
2015-02-02T16:16:51 < Tectu> kakeman, while the girls from all the other countries prefer to not doing homework and doing drugs all the time
2015-02-02T16:17:03 < Tectu> kakeman, swiss girls however tent to drink a lot when going out
2015-02-02T16:17:22 < Tectu> kakeman, which you may use to your advantage if required lol
2015-02-02T16:17:50 < kakeman> that is common for finnish and swiss girls
2015-02-02T16:17:53 < Tectu> kakeman, but to be honest most swiss girls suck in bed, tho.

2015-02-02T16:19:40 < kakeman> no

2015-02-02T16:20:24 < jpa-> Tectu: so just teach her
2015-02-02T16:20:24 < Tectu> R2COM, I certainly will. If we get lucky, you'll receive a girl who will punish you for it.
2015-02-02T16:20:35 < kakeman> I don't have experience enough to base my opinion to with the last one Tectu
2015-02-02T16:20:52 < Tectu> lol, that honesty
2015-02-02T16:20:54 < Laurenceb> <Tectu> kakeman, but to be honest most swiss girls suck in bed, tho.
2015-02-02T16:20:59 < Laurenceb> lol like Tectu would know
2015-02-02T16:21:07 < Tectu> now I am concerned about how many people here are < 18
2015-02-02T16:21:10 < Tectu> Laurenceb ...
2015-02-02T16:21:47 < jpa-> yes Laurenceb is one, though only per mental age
2015-02-02T16:21:56 < PeterM> conversation = dead
2015-02-02T16:21:56 < jpa-> the rest are probably of age

2015-02-02T16:23:04 < Tectu> and for full irony he even has a swiss army knife...
2015-02-02T16:26:07 < Tectu> why is it that whenever Laurenceb shows up the conversations end?
2015-02-02T16:26:36 < Laurenceb> cuz im paid to shut you up
2015-02-02T16:27:09 < Tectu> R2COM, no idea. 95% of the sluts in switzerland are not swiss anyway. and that 5% are expensive as fuck.
2015-02-02T16:27:52 < Tectu> 65% eastern europe, 25% russia, 10% unknown
2015-02-02T16:27:53 < Tectu> yes
2015-02-02T16:28:01 < jpa-> you must have done deep research
2015-02-02T16:28:06 < Tectu> R2COM, well, the really 100% swiss sluts are expensive as fuck
2015-02-02T16:28:17 < Tectu> jpa-, actually I did
2015-02-02T16:28:25 < Tectu> R2COM, that is for high roller one night
2015-02-02T16:28:33 < Tectu> R2COM, and I am sure there are more expensive ones as well
2015-02-02T16:28:36 < Laurenceb> why am i not surprised Tectu knows
2015-02-02T16:28:38 < Tectu> R2COM, let me look something up.
2015-02-02T16:28:45 < Tectu> R2COM, yes, they are.
2015-02-02T16:28:59 < gxti> quality crap in here i see
2015-02-02T16:29:04 < Tectu> R2COM, there also one "company" where you can specify what you want. some swiss dudes just need that 18 years old ukraine feeling. dunno.
2015-02-02T16:29:41 < Laurenceb> http://www.theregister.co.uk/2014/11/08/vulturetrending/
2015-02-02T16:29:49 < Tectu> R2COM, of course, anything in .ch is legal
2015-02-02T16:30:13 < Tectu> R2COM, looks like it's hard to get the real swiss experience for under 1k€ (1 hours that is)
2015-02-02T16:30:32 < Laurenceb> wtf
2015-02-02T16:30:34 < Tectu> R2COM, I can do some calls to get officiall quotes if you want
2015-02-02T16:30:39 < jpa-> except if you are not that picky and take Tectu instead
2015-02-02T16:30:43 < Laurenceb> lol
2015-02-02T16:30:50 < Fleck> http://fleck.rullz.lv/skatcam/viewcam.php?cam=4 << yay! :D
2015-02-02T16:30:52 < Tectu> 12k was the night thing that a friend paid. It was definitely a high-end slut but not sure how much higher they get
2015-02-02T16:31:03 < Laurenceb>  "a friend"
2015-02-02T16:31:29 < Tectu> R2COM, let me do a call...
2015-02-02T16:31:53 < Tectu> R2COM, people who can afford true swiss prostitutes usually don't go for the whole night due to pricing...
2015-02-02T16:31:56 < Fleck> :D
2015-02-02T16:32:12 < Tectu> I mean 12k€ is what a higher educated person with 5 years of experience earns here in a month
2015-02-02T16:32:18 < Tectu> so definitely nothing you can do every night
2015-02-02T16:32:20 < Fleck> nice toppic for ##stm32
2015-02-02T16:32:34 < gxti> this is what real pro EEs talk about i guess
2015-02-02T16:32:37 < Tectu> I don't think that anybody in here expects any stm32 talk here anyway
2015-02-02T16:32:38 < gxti> i wouldn't know
2015-02-02T16:33:10 < jpa-> higher educated jpa with 5 years of experience only earns 3k€ a month.. damn, can't buy a prostitute for Tectu's birthday
2015-02-02T16:33:39 < Tectu> jpa-, huh? I thought .fi was one of those "overpriced" countries as well?
2015-02-02T16:34:02 < jpa-> prices are heavy but wages not ;)
2015-02-02T16:34:16 < Tectu> jpa-, an electronics engineer bachelor degree earns 8kCHF minimum in first year here. That is nearly 8k€
2015-02-02T16:34:17 -!- Lerg [~Lerg@188.226.45.254] has joined ##stm32
2015-02-02T16:34:21 < Tectu> and that is really first month wage
2015-02-02T16:34:22 < Laurenceb> inbe someone asks about wages for gigolos
2015-02-02T16:34:26 < Tectu> jpa-, your country is doing it wrong then :P
2015-02-02T16:34:44 < jpa-> probably
2015-02-02T16:34:49 < Tectu> jpa-, now I feel bad and I want to send you half my money :(
2015-02-02T16:34:51 < kakeman> Tectu: say again?
2015-02-02T16:34:52 < kuldeepdhaka> ##pro32
2015-02-02T16:34:58 < jpa-> though we do have pretty good social security
2015-02-02T16:35:01 < BrainDamage> Tectu: i guess my friend with a PhD got ripped off since he got 8kCHF/month for a job in zurich
2015-02-02T16:35:12 < kuldeepdhaka> our guru Tectu will solve all problem
2015-02-02T16:35:25 < kuldeepdhaka> ask him anything and solve all problems
2015-02-02T16:35:29 < Tectu> kakeman, 4k€ is the officially lowest possible wage for anybody working 5 days a week (42 hours) that is defined by the government. And that is really for people who clean toilets
2015-02-02T16:35:41 < Tectu> kakeman, any bachelor EE gets 9k€ in first year of work.
2015-02-02T16:35:45 < Tectu> 9k€ a month
2015-02-02T16:35:57 < Tectu> BrainDamage, forgein people get ripped of most of the time :P
2015-02-02T16:36:06 < kakeman> how the hell does that work
2015-02-02T16:36:12 < karlp> hrm, my takehome is only baout 3keuro / month too.
2015-02-02T16:36:30 < karlp> is that 4k minimum take home or gross?
2015-02-02T16:36:42 < Tectu> R2COM, My prof used to work in some company doing digital signal design stuff (some advanced stuff for satelites and fuck) and he had a wage of 15k€ / month after 4 years of work
2015-02-02T16:37:03 < Tectu> karlp, home or gross?
2015-02-02T16:37:20 < Tectu> R2COM, algorithms mainly, design just for prototypes, not finished products
2015-02-02T16:37:27 < kakeman> I don't go to work for 2k month leaving me with nothing after month
2015-02-02T16:37:35 < jpa-> Tectu: before or after tax
2015-02-02T16:37:35 < kakeman> I rather learn hacking
2015-02-02T16:37:59 < Tectu> if anybody cares: my sister did a 4 years apprenticeship after compulsory school in a drug store and she ears 4'200€ a month... and that's really one of the lowest you can get
2015-02-02T16:38:06 < Tectu> jpa-, before. Taxes aren't that high, tho.
2015-02-02T16:38:15 < karlp> before is a useless number
2015-02-02T16:38:19 < Tectu> R2COM, not that many. most forgeiners don't do engineering here...
2015-02-02T16:38:20 < kuldeepdhaka> "<Tectu> kakeman, 4k€ is the officially lowest possible wage for anybody working 5 days a week (42 hours) that is defined by the government. And that is really for people who clean toilets"  country?
2015-02-02T16:38:21 < jpa-> my 3k gross is 2k take home
2015-02-02T16:38:32 < Tectu> jpa-, let me get get something...
2015-02-02T16:38:42 < Tectu> kuldeepdhaka, switzerland
2015-02-02T16:38:43 < karlp> I'm on about 3k euro take home
2015-02-02T16:38:53 < kakeman> Tectu: what you do with that amount of money=?
2015-02-02T16:39:07 < kakeman> once ate a pizza in swissland
2015-02-02T16:39:11 < Tectu> kakeman, well, stuffhere is more expensive than for you I guess
2015-02-02T16:39:18 < jpa-> Tectu: what does an average home (say, 80 m^2 or so) cost there?
2015-02-02T16:39:30 < kakeman> it was small, not that special and cost 20euros
2015-02-02T16:39:30 < Tectu> jpa-, need to google that. I have no idea about those prices
2015-02-02T16:39:34 < Tectu> jpa-, buying or rent?
2015-02-02T16:39:39 < Tectu> kakeman, totally usual
2015-02-02T16:39:48 < jpa-> Tectu: maybe rent would be more useful number
2015-02-02T16:40:06 < ReadError> 12k on some snatch?
2015-02-02T16:40:07 < ReadError> gtfo ;p
2015-02-02T16:40:14 < jpa-> Tectu: do you still live home or how much rent do you pay?
2015-02-02T16:40:16 < ReadError> opps was scrolled up
2015-02-02T16:40:34 < Tectu> jpa-, how many rooms?
2015-02-02T16:40:40 < jpa-> Tectu: 3
2015-02-02T16:40:42 < Tectu> jpa-, I live at my parents.
2015-02-02T16:41:05 < karlp> jpa-: web says 6k gross in switz is 4.5k net (ish)
2015-02-02T16:41:13 < Tectu> jpa-, prices start at 1'100€ a month
2015-02-02T16:41:28 < jpa-> not much more than here
2015-02-02T16:41:50 < jpa-> you could probably get a 3-room dumpster for 800€ or so
2015-02-02T16:41:57 < Tectu> R2COM, my parents bought a flat with something like 100m^2, 3 1/2 rooms and it was 320k€ back then. And it's remote place
2015-02-02T16:42:33 < Tectu> R2COM, I can get you a swiss slut for one night for 3k€ starting. But anal is extra she says
2015-02-02T16:42:47 < karlp> I'm renting out my old place (48m2) for ~950 euro / month
2015-02-02T16:43:02 < Tectu> let me do another phone call...
2015-02-02T16:43:09 < Tectu> R2COM, anything else I should ask?
2015-02-02T16:43:16 < jpa-> my 3 room 80m^2 rowhouse appartment cost 180ke.. 7km from city center
2015-02-02T16:43:26 < Tectu> jpa-, so prices are similar
2015-02-02T16:43:33 < Tectu> R2COM, such as?
2015-02-02T16:43:48 < Tectu> R2COM, they usually don't do fecal stuff...
2015-02-02T16:43:57 < jpa-> "how do you know"?
2015-02-02T16:44:09 < karlp> houses sound cheapish for you jpa
2015-02-02T16:44:11 < Tectu> Why am I doing this again?
2015-02-02T16:44:20 < gxti> Tectu: hopefully your own personal amusement
2015-02-02T16:44:34 < Tectu> BrainDamage, I assume that your friend with 8k still gets way more than in your country (for the same job) ?
2015-02-02T16:45:04 < Tectu> BrainDamage, I live close to the italian border. there are hundrets of italian people who live in your country and come work here.
2015-02-02T16:45:20 < Tectu> BrainDamage, they are just some low quality construction guys, tho. no engineers
2015-02-02T16:45:22 < qyx_> karlp: jpa- hm, not that expensive as i expected
2015-02-02T16:45:23 < BrainDamage> Tectu: yes, altough your life costs are considerably higher than here, the net effect is approximately 2x
2015-02-02T16:45:30 < Tectu> BrainDamage, fun fact: they have to give 1/4 to the customs when they pass :P
2015-02-02T16:45:39 < jpa-> karlp: yeah, though the rental prices are a bit large currently - i'm paying 250e/month maintenance + 500e/month loan, renting a similar appartment would be atleast 1000e/month
2015-02-02T16:45:46 < gxti> loleuros
2015-02-02T16:45:59 < karlp> qyx_: reykijavik has gone up a lot in the last few years, price per square meter when I bought my old place was only maybe 60% of the new place I bought
2015-02-02T16:46:11 < BrainDamage> Tectu: my sister does that, she's a programmer for dauf / galenica
2015-02-02T16:46:24 < qyx_> karlp: we are paying ~900e/m for about 80m^2
2015-02-02T16:46:29 < Tectu> R2COM, oh, you want a high roller? I don't have any contacts there, would need to ask a friend first.
2015-02-02T16:46:34 < qyx_> but this is half-eastern eu
2015-02-02T16:46:48 < BrainDamage> Tectu: even with taxes removing a decent fraction of the income,it's still pretty convient due to much lower life cost here

2015-02-02T16:48:45 < Tectu> R2COM, 3k€ from some 28 years old swiss girl that blows you all night without any special action?

2015-02-02T16:55:08 < Tectu> not really considered to be switzerland from rest of switzerland :P
2015-02-02T16:55:15 < Tectu> seriously, the italian part of switzerland is so weird
2015-02-02T16:55:35 < Tectu> they even have some kind of right-extreme "partei" in our parlament
2015-02-02T16:56:15 < BrainDamage> i know, there's usually friction between border commuters and those parties
2015-02-02T16:56:34 < BrainDamage> apparently they see them as invaders attempting to steal food or something like that
2015-02-02T16:57:36 < Tectu> lol :D
2015-02-02T16:59:42 < BrainDamage> also since daily commute on the track that crosses the border, i get to meet a lot of people that do so, my personal impression is that italians which go reside there become the worst offenders re "fear of invasors"

2015-02-02T17:00:45 < Tectu> I am not even 1% patriotic
2015-02-02T17:00:57 < Tectu> and I don't care who is in this country as long as they behave as supposed to.
2015-02-02T17:01:08 < Tectu> there are many swiss people I would love to throw out of this country
2015-02-02T17:01:38 < kakeman> italians come to swissland to jerk your ass in trains?
2015-02-02T17:02:15 < Tectu> R2COM, where are you from again?
2015-02-02T17:02:29 < Tectu> R2COM, just last year there was a vote in switzerland and the folks decided to limit the amount of immigrants
2015-02-02T17:02:32 < kakeman> nice thing when we took train to italy from amsterdam. we had some supplies with us
2015-02-02T17:02:50 < Tectu> R2COM, sadly that is agains the biliteral contracts that .ch has with the EU (we are not part of the EU but we have some contracts to make live easier (especially custom stuff))
2015-02-02T17:03:07 < kakeman> I had a bad feeling at italian border when we came back
2015-02-02T17:03:26 < kakeman> so we flushed our supplies down the toilet
2015-02-02T17:04:13 < kakeman> next thing military guys with machinepistols come in and go thru all our pockets
2015-02-02T17:04:23 < Tectu> kakeman, lulz
2015-02-02T17:04:35 < Tectu> kakeman, hint: never ask them if you can hold the gun. BAAAD idea
2015-02-02T17:04:52 < Tectu> BrainDamage, anyway. They are building a new "customs station for persons and lugage" here now.
2015-02-02T17:04:55 < kakeman> don't bother them. just hold it
2015-02-02T17:05:03 < Tectu> BrainDamage, people are pissed of by those italian imigrants for some reason
2015-02-02T17:05:48 < PeterM> dey terk er jerbs
2015-02-02T17:05:50 < Tectu> kakeman, I used to travel a lot in "those trains" where you get body searched etc. Fun fact is that whenever they see a swiss ID they let you. They don't even open your bags. then there are some german dudes next to us and they are searched :d
2015-02-02T17:05:58 < Tectu> and this was not some 1-time inccidence. It happened all the time
2015-02-02T17:06:05 < Tectu> swiss IDs are like the holy grail when traveling
2015-02-02T17:06:14 < Tectu> also at the airports. swiss ID -> super fast check-in
2015-02-02T17:06:59 < Tectu> I tend to have many "friends" from germany, italy and france to visit or for business travels. It's alawys a pain in the ass to travel with them. Everything takes longer and more exhausting
2015-02-02T17:07:05 < Tectu> never had to open my bags before
2015-02-02T17:07:13 < Getty> i remember the day when brazil wanted to f**k US, and when i reached rio airport, they had 2 lines: US and Other..... US had to made "TSA-like check" with photo and co., all others were just waived through
2015-02-02T17:07:20 < kakeman> I though finnish iceman passport would do but they saw us as potential nigerian immigrants
2015-02-02T17:07:33 < Getty> and later a brazil friend told me, that they dont have any storage for the information, they just have thrown it away after gathering the data
2015-02-02T17:07:56 < Getty> that was brazils reaction for their citizens being required todo TSA in US
2015-02-02T17:08:10 < Getty> sadly that is over ;) but it was fun to see
2015-02-02T17:08:23 < Tectu> It's time to leave for me.
2015-02-02T17:08:50 < BrainDamage> Tectu: i used to have a special id until i was 18, issued by goverment since i am a son of a border patrol officer, 0 checks either

2015-02-02T17:19:43 < Steffanx> but you are not allowed to use that altium for commercial projects. At least i believe that was the deal with the old academic altium license.
2015-02-02T17:19:52 < Steffanx> i guess you do not have such license?

2015-02-03T12:37:23 < jpa-> yeah, that is normal
2015-02-03T12:38:02 < jpa-> the flat ones go with appliances that have two layers of insulation between user and any high-voltage part
2015-02-03T12:38:28 < jpa-> whereas old non-grounded devices around here used round plugs similar to schuko but without ground

2015-02-03T13:50:35 < yots_> Hi, this is a bit silly but I cannot find anything about the CAN SCE interrupt in the reference manual. It's an STM32F10x board
2015-02-03T13:51:11 < yots_> It simply states that it exists, but there's no further reference - at least not by that name.
2015-02-03T14:00:43 < _Sync_> wtf
2015-02-03T14:01:31 < _Sync_> sending over spi works, receiving not
2015-02-03T14:01:44 < zyp> yots_, SCE?
2015-02-03T14:02:22 < zyp> status change error?
2015-02-03T14:03:27 < zyp> yeah
2015-02-03T14:04:43 < yots_> OH! yes you're right
2015-02-03T14:04:45 < zyp> SCE is any of the interrupt bits in ESR and MSR
2015-02-03T14:05:21 < yots_> even then it's only mentioned in one of the graphs
2015-02-03T14:05:39 < yots_> yeah I see how it consolidates them now
2015-02-03T14:06:16 < yots_> thank you!
2015-02-03T14:06:25 < zyp> well, if it weren't for the fact that the CAN peripherals have four separate IRQ lines, it wouldn't even mention which interrupt bits are routed to which :p
2015-02-03T14:07:06 < zyp> but the fact that the acronym listed in the NVIC chapter isn't mentioned directly is a bit bad :p

2015-02-03T14:23:32 < dongs> You've identified the Audio Amplifier, but what's the quality of the DAC sending signal out through the 3.5mm? I'm too lazy to walk around with a portable external DAC and AMP via USB OTG, but I'd still like to have a halfway decent experience listening to my lossless audio with my Sennheisers. I'm in between the Nexus 6 and the Note 4 for my next handset, and I'll just pick the one with the best audio experience.

2015-02-03T14:30:47 < PeterM> should tell him to just get a pono
2015-02-03T14:31:04 < dongs> it would probably cost less than either of  those phones!
2015-02-03T14:31:22 < zyp> I think I actually have some lossless music on my phone, because I was too fucking lazy to transcode it when I put it on there
2015-02-03T14:31:48 < PeterM> zyp yeah i have some flacs, but only because they were the most seeded at the time
2015-02-03T14:33:03 < zyp> heh
2015-02-03T14:33:03 < karlp> GargantuaSauce: just lossless everywhere, why not?
2015-02-03T14:33:16 < dongs> because dumb waste of space

2015-02-03T14:33:49 < zyp> dude, my phone can fit at least 20!
2015-02-03T14:33:59 < GargantuaSauce> heh
2015-02-03T14:34:20 < dongs> set higher compression ratio on flac
2015-02-03T14:34:23 < dongs> then you can fit more

2015-02-03T14:35:18 < PeterM> or anywhere with shit reception
2015-02-03T14:35:45 < zyp> yeah, trains in the norwegian mountains accounts for another huge fraction
2015-02-03T14:36:18 < PeterM> because if you had decent reception you'd be watchign you/red tube and on irc instead of listening to music

2015-02-03T15:51:51 < dongs> on that panel
2015-02-03T15:51:54 < dongs> so much wasted space
2015-02-03T15:52:00 < dongs> if  they have 2 boards stacking on that shit
2015-02-03T15:52:01 < PeterM> i dunno either- especially this tiem of year i dont expect it to be that humid
2015-02-03T15:52:14 < dongs> why ditdn tehy put the circle 'stack' board in the waste space

2015-02-03T17:18:41 < DrLuke> Hello, I have this code: http://pastebin.com/dtNkgQJy  For some reason, once the interrupt fires, the main code stops running. Consecutive interrupts still run though (the dac outputs the waveform I want). Is there anything obvious I'm doing wrong?
2015-02-03T17:19:25 < DrLuke> It seems like it doesn't properly return to the main code from the interrupt
2015-02-03T17:19:51 < zyp> you're not clearing the interrupt flag in the ISR
2015-02-03T17:20:00 < zyp> so it immediately retriggers on the same flag
2015-02-03T17:20:41 < DrLuke> Oh, I  have to do that manually?
2015-02-03T17:21:17 < zyp> of course, how would it else know which flags you've handled?
2015-02-03T17:22:00 < zyp> the same IRQ is responsible for handling all interrupts from TIM6, there's a bunch of possible interrupts from each timer
2015-02-03T17:22:03 < DrLuke> That of course makes sense. Thanks!
2015-02-03T17:22:06 < zyp> update, channel, etc

2015-02-03T17:22:30 < DrLuke> I'm a bit spoiled from AVRs where each event has it's own irq :P
2015-02-03T17:22:34 < zyp> so this allows you to only handle and clear one flag, and if more if set, it'll retrigger immediately
2015-02-03T17:22:50 < zyp> heh

2015-02-03T17:27:06 < jpa-> you mean, from AVR where there are only a few events :)
2015-02-03T17:27:31 < jpa-> probably over a thousand different IRQ sources on an STM32
2015-02-03T17:28:06 < zyp> that sounds a bit high

2015-02-03T17:29:05 < jpa-> maybe a bit high yeah
2015-02-03T17:30:02 < karlp> DrLuke: I think you should be including libopencm3/cm3/nvic.h too, not the dispatch header

2015-02-03T17:30:59 < zyp> there's less than 100 IRQs, and I'd guess that the average peripheral don't have more than 10 interrupt sources
2015-02-03T17:31:02 < zyp> or?
2015-02-03T17:31:56 < zyp> advanced timers have 8, as far as I can see
2015-02-03T17:33:04 < jpa-> you're right
2015-02-03T17:33:32 < jpa-> dma has quite many, but they go to different IRQs anyway

2015-02-03T17:33:40 < zyp> yeah
2015-02-03T17:33:43 < jpa-> EXTI has a few going to same IRQ, but less than 10 per irq

2015-02-03T17:34:40 < zyp> I guess the otg cores have the largest numbers of sources feeding a single IRQ
2015-02-03T17:35:33 < zyp> since there's multiple levels of interrupt sources in them
2015-02-03T17:35:49 < DrLuke> karlp: I was told to not use cm3/nvic.h, but dispatch instead
2015-02-03T17:35:52 < DrLuke> now I'm confused :)
2015-02-03T17:36:05 < DrLuke> Anyway, it all works now! http://a.pomf.se/ruuoag.png
2015-02-03T17:36:08 < DrLuke> thanks to everyone <3
2015-02-03T17:37:04 < Tectu> welcome
2015-02-03T17:37:52 < karlp> DrLuke: who told you that?
2015-02-03T17:38:09 < karlp> the examples in the libopencm3-examples repo are all using cm3/nvic.h
2015-02-03T17:38:22 < DrLuke> I won't tell on my friend ;P
2015-02-03T17:38:26 < DrLuke> I'll use that then
2015-02-03T17:39:21 < DrLuke> thanks karlp
2015-02-03T17:40:41 < karlp> DrLuke: you would have been missing all the common core nvic settings, and only getting part specific defines.
2015-02-03T17:41:11 < karlp> cm3/nvic includes the dispatch to get the part specific pieces
2015-02-03T17:41:39 < DrLuke> It still kind of worked :P
2015-02-03T17:42:18 < zyp> looks like OTG_HS has 16 possible interrupt sources for each device endpoint pair, so that's 96 interrupts just for device endpoints
2015-02-03T17:43:29 < karlp> DrLuke: yeah, for today it would have, but you would have gotten cponfused with it eventually
2015-02-03T17:43:39 < DrLuke> Yup
2015-02-03T17:45:22 < zyp> and 88 for host mode channels
2015-02-03T17:45:44 < zyp> with global interrupts and stuff, I guess there's around 200 total in OTG_HS
2015-02-03T17:46:07 < zyp> fewer in OTG_FS since it has fewer endpoints and no DMA
2015-02-03T17:47:20 < zyp> oh, no, there's more host mode channels in OTG_HS
2015-02-03T17:47:33 < zyp> so 132
2015-02-03T17:50:53 < DrLuke> karlp: My friend just told me that dispatch/nvic.h includes stm32/f0/nvic.h which includes cm3/nvic.h
2015-02-03T17:51:00 < DrLuke> so including dispatch seems to be the correct way
2015-02-03T17:54:03 < zyp> hmm
2015-02-03T17:54:07 < karlp> well, it works, but really the include from stm32/f0/nvic to cm3/nvic is the one that should be dropped
2015-02-03T17:54:19 < karlp> because cm3/nvic includes dispatch :)
2015-02-03T17:54:21 < DrLuke> eh nevermind... cm3/nvic.h includes dispatch
2015-02-03T17:54:24 < DrLuke> heh
2015-02-03T17:54:27 < zyp> jpa-, there's around 370 interrupt sources in the two usb cores in an F4
2015-02-03T17:54:28 < karlp> and nvic is a core cortex m periph
2015-02-03T17:54:49 < zyp> 135+235-ish

2015-02-03T22:29:33 < BrainDamage> sure, in his case it's so prevalent it's making me cry
2015-02-03T22:29:50 < BrainDamage> now he's thinking to make a 200kg electric vehicle
2015-02-03T22:30:32 < BrainDamage> despite having 0 experience with electric motors, switching circuits, or even mechanical engineering
2015-02-03T22:30:44 < BrainDamage> oh and he wants to design his own controller
2015-02-03T22:31:12 < BrainDamage> maybe i should introduce him to beaky :V
2015-02-03T22:31:20 < gxti> sounds like he's just really excited about making stuff, even if he can't
2015-02-03T22:32:13 < gxti> there are worse ways to be

2015-02-03T22:32:23 < qyx_> more speed
2015-02-03T22:33:08 < kakeman> talking about me?
2015-02-03T22:33:36 < BrainDamage> i would have no problems with it execept: he runs into a grinding halt, starts asking me, and i tell him he's doing it all wrong, then he gets pissed at me because i told him that what he got so far has to be scrapped
2015-02-03T22:34:45 < BrainDamage> so i tell him to leave me alone, if he doesn't want my opinion he shouldn't ask for it, and after a while he comes back admitting he was wrong with a new insane request
2015-02-03T22:34:51 < BrainDamage> so far this cycle has repeated 3 times
2015-02-03T22:35:09 < BrainDamage> so no, i'm not happy of his excitement
2015-02-03T22:36:23 < kakeman> only 3times

2015-02-03T23:37:26 < Fleck> kinda offtopic, but still, stm8 question about uart... http://www.st.com/st-web-ui/static/active/en/resource/technical/document/reference_manual/CD00190271.pdf << page 321, is a diagram and page 326 says: During an UART transmission, data shifts out least significant bit first on the UART_TX pin. In this mode, the UART_DR register consists of a buffer (TDR) between the internal bus and the transmit shift register
2015-02-03T23:37:35 < Fleck> how many bytes is that buffer?

2015-02-03T23:39:24 < Fleck> on page 327 there is also a sentence, that confuses me: Write the data to send in the UART_DR register (this clears the TXE bit). Repeat this for each data to be transmitted in case of single buffer
2015-02-03T23:39:56 < Fleck> in case of single buffer, what's the case of multiple buffers? :)

2015-02-04T00:41:57 < dongs> by buffer they just mean it as a single byte 'buffer' as the register itself before it moves into shift in/out hardware register
2015-02-04T00:43:59 < Fleck> yeah, as I could not find any size info, started to think the same!
2015-02-04T00:44:13 < gxti> it probably refers to how you use it, not what the hardware is
2015-02-04T00:44:25 < gxti> single buffer meaning write new byte when TXE, as opposed to 'no buffer' i.e. write new byte when idle
2015-02-04T00:44:28 < gxti> or something.

2015-02-04T01:00:44 < Laurenceb__> yeah
2015-02-04T01:01:21 < Laurenceb__> why so big...
2015-02-04T01:01:22 < gxti> qyx_: i did a test implementation that i never fully used, it just stuffed a magic value into an uninitialized var and did a cpu reset
2015-02-04T01:01:39 < gxti> er, system reset
2015-02-04T01:02:55 < qyx_> yep, i use iwdg for system reset too
2015-02-04T01:03:12 < gxti> oh wait you said wwdg. no idea about that one.
2015-02-04T01:03:14 < qyx_> but i would like to use some watchdog in the bootloader
2015-02-04T01:03:18 < dongs> Laurenceb__: because ivan is a manchild troll
2015-02-04T01:03:26 < gxti> well, i do that same reset procedure in bootloader every time anyway
2015-02-04T01:03:40 < qyx_> and the flashed firmware may be configured to not use it, so i need to stop it after boot
2015-02-04T01:04:05 < gxti> if the bootloader configures any peripherals, it's easier to just reset everything than to try to fix it
2015-02-04T01:04:15 < gxti> and i had a full network stack running...
2015-02-04T01:04:24 < qyx_> but the problem remains
2015-02-04T01:04:29 < qyx_> i reset the bootloader
2015-02-04T01:04:33 < qyx_> it starts watchdog again
2015-02-04T01:04:40 < qyx_> starts parsing and authenticating the firmware
2015-02-04T01:04:45 < qyx_> and before boot i need to disable it
2015-02-04T01:05:11 < gxti> you do your 'magic value' check before configuring anything, including iwdg
2015-02-04T01:05:13 < qyx_> or maybe i just need to implement exception handlers and make the parsing more error resistant :S
2015-02-04T01:05:50 < gxti> https://github.com/mtharp/laureline-firmware/blob/master/bootloader/src/main.c
2015-02-04T01:06:11 < gxti> boot -> do bootloadery stuff -> set value -> reset -> check value before anything else, if set then clear it and jump
2015-02-04T01:06:52 < qyx_> oh
2015-02-04T01:07:15 < qyx_> where do you store this "set value" to be there after reset?
2015-02-04T01:07:40 < gxti> reset_and_jump() sets it, main() checks it
2015-02-04T01:08:12 < gxti> which of course means gpios get setup, guess i should move it into SystemInit() or something. but that's pretty low-impact.
2015-02-04T01:08:29 < gxti> ideally you want to do it as soon as humanly possible

2015-02-04T01:09:24 < gxti> but i'm lazy and the system init code is shared with the main program so it would be awkward to shove some bootloader stuff in there. one of these days i will break the bootloader out into a totally separate project.
2015-02-04T01:09:32 < qyx_> your .uninit is placed in the sram
2015-02-04T01:09:44 < qyx_> does that mean that sram contents are kept during reset?
2015-02-04T01:09:56 < gxti> sram is kept, yes. crt0 normally clears it but that section is excluded.
2015-02-04T01:10:04 < qyx_> huh
2015-02-04T01:10:05 < qyx_> ok
2015-02-04T01:10:10 < qyx_> never though about that
2015-02-04T01:10:11 < gxti> explicitly in my linker script, not a standard thing: https://github.com/mtharp/laureline-firmware/blob/master/bootloader/ports/STM32F107xB.ld
2015-02-04T01:10:17 < qyx_> yepp, i saw that
2015-02-04T01:11:42 < gxti> since i have a custom crt0 anyway i guess it would be even easier to just put the jump into crt0 before ram is cleared, then no section required
2015-02-04T01:13:13 < gxti> would also boot a little faster since it doesn't end up writing all of sram twice

2015-02-04T01:30:57 < qyx_> they may, but not always
2015-02-04T01:31:18 < zyp> again, what are you trying to protect against?
2015-02-04T01:31:20 < qyx_> overwriting flash contents requires a bit more effort

2015-02-04T01:32:46 < qyx_> security will always be halfassed
2015-02-04T01:32:53 < qyx_> theres nothing like 100%
2015-02-04T01:33:20 < qyx_> but if some attack vector is known even before implementing it, theres something wrong
2015-02-04T01:33:28 < qyx_> uhm, implementing it
2015-02-04T01:33:46 < qyx_> i mean implementing a feature which would allow an attack known at that time
2015-02-04T01:35:15 < zyp> if you have a hole which allows for writing arbitrary memory, it already allows you to inject and execute arbitrary code in supervisor context
2015-02-04T01:35:43 < zyp> and then it's pretty irrelevant that it also allows for bypassing the bootloader verification
2015-02-04T01:35:51 < qyx_> under some conditions
2015-02-04T01:36:04 < zyp> what conditions?
2015-02-04T01:36:23 < qyx_> attacking single value is surely easier as remote code execution or writing large chunks of data

2015-02-04T01:37:32 < qyx_> you said nothing wrong, its only about making obvious things more hard
2015-02-04T01:37:49 < zyp> security by obscurity :=
2015-02-04T01:38:11 < zyp> :)
2015-02-04T01:38:17 < qyx_> hardly on a public code
2015-02-04T01:40:20 < qyx_> many common public exploits or theoretical attacks allows you eg. "read first 32 bytes of a message", "write arbitrary single byte on the stack", etc
2015-02-04T01:40:51 < qyx_> if you can overwrite larger chunks of memory or even remotely program the flash, you fucked it badly
2015-02-04T01:41:00 < zyp> either way, if you care about that sort of exploits, the right way to mitigate the risk is to run as much of the code as possible in unprivileged mode with the MPU set to cut off access to all unneeded memory areas
2015-02-04T01:41:22 < qyx_> yes
2015-02-04T01:41:38 < qyx_> thats why i am exploring freertos again
2015-02-04T01:42:54 < zyp> hmm, that reminds me
2015-02-04T01:43:19 < qyx_> thats the same as setting a password on a physically accessible wifi accesspoint
2015-02-04T01:43:27 < zyp> I've got some stm32 based board that I've considered writing my own firmware for
2015-02-04T01:43:28 < qyx_> you can always break it if you care enough
2015-02-04T01:43:36 < qyx_> but it will filter out 99% of people
2015-02-04T01:44:24 < zyp> so I considered looking for an exploit in the original firmware that allows me to execute code on it so I can bootload my own firmware over USB
2015-02-04T01:44:34 < zyp> since it doesn't appear to ship with a bootloader
2015-02-04T01:49:12 < qyx_> anyway, even mpu doesn't help you, because you can upload your firmware
2015-02-04T01:49:33 < qyx_> thats the main reason for fw authentication
2015-02-04T01:51:40 < zyp> huh?
2015-02-04T01:51:53 < zyp> how is that relevant?
2015-02-04T01:52:26 < zyp> the uploaded firmware isn't executed before it's authenticated, right?
2015-02-04T01:52:36 < qyx_> yes
2015-02-04T01:53:08 < zyp> and what do you mean that the MPU doesn't help?
2015-02-04T01:53:52 < qyx_> the service allowing remote firmware upgrade needs to right access
2015-02-04T01:54:02 < qyx_> *have
2015-02-04T01:55:17 < zyp> sure
2015-02-04T01:55:40 < zyp> that only means it has to be audited extra
2015-02-04T01:56:20 < qyx_> i just moved the auth part to the bootloader which also does flashing
2015-02-04T01:56:37 < qyx_> so the upload service can be totally broken

2015-02-04T02:10:04 < BrainDamage> the description is severely disappointing. wow.
2015-02-04T02:10:33 < dongs> Right, back to work again for me. We are tidying up the Zano OS API and aligning everything on the SDK. The team had a quick play with a Windows mobile app today too, just initial functional testing but its all good and working using the SDK.
2015-02-04T02:10:47 < dongs> the magical SDK
2015-02-04T02:12:30 < dongs> <ivan> Zano typically draws 2.5-3.5A with small peaks up to 5.5 but for short periods of time.
2015-02-04T02:13:05 < dongs> (350 milliampere hours) / (3.5 amperes) =
2015-02-04T02:13:06 < dongs> 6 minutes
2015-02-04T02:13:14 < dongs> (350 milliampere hours) / (5.5 amperes) =
2015-02-04T02:13:17 < dongs> 3.8 minutes
2015-02-04T02:14:29 < qyx_> windows mobile app? does anybody use windows mobile?
2015-02-04T02:14:35 < dongs> Also JST was chosen as it is readily available so your not restricted to using our brand battery though we would suggest you do to protect your Z

2015-02-04T05:10:09 < dongs> thats not bad, that might be all i'll ever sell lolooll
2015-02-04T05:10:16 < dongs> in which case it'll pay off with first board made
2015-02-04T05:21:14 < emeb_mac> what chip?

2015-02-04T05:24:20 < dongs> this is the piece of shit that requires 1.15V core voltage
2015-02-04T05:24:36 < emeb_mac> 1.15 - that's picky
2015-02-04T05:24:38 < dongs> in addition to 1.2V some other voltage

2015-02-04T11:35:02 < dongs> i wonder how shit it is
2015-02-04T11:35:08 < dongs> 30x20cm work area or somethign
2015-02-04T11:35:12 < dongs> can that  trash do stencils?

2015-02-04T11:35:39 < dongs> loo
2015-02-04T11:36:24 < dongs> People have successfully made solder paste stencils using transparency film instead of metal sheets. Transparency film is easily cut on a 40w CO2 laser. Metals require hundreds of watts of power to cut. A 40w CO2 laser won't even scuff thin aluminum or any other metal.
2015-02-04T11:36:29 < dongs> oh god its only good for garbage stencils
2015-02-04T11:41:26 < ReadError> looked in to those

2015-02-04T12:47:20 < ReadError> sneaky chinese
2015-02-04T12:48:28 < thesame> hi everyone
2015-02-04T12:49:03 < thesame> could you please explain me why I can flash my code via usart bootloader using stm32flash, when my code is running?
2015-02-04T12:49:27 < jpa-> or perhaps because up to 70% parts are off the pads?
2015-02-04T12:49:47 < thesame> for example, I flashed miniblink from libopencm3-examples, and LED blink finely. But I still can issue stm32flash to flash it
2015-02-04T12:49:47 < qyx_> you either used "can" instead of "can't" or your code isn't running
2015-02-04T12:50:35 < jpa-> do you have some RTS signal connected to reset or something?
2015-02-04T12:51:09 < qyx_> how do you connect to the serial?
2015-02-04T12:51:15 < thesame> via pl2303
2015-02-04T12:51:51 < thesame> i run ./stm32flash -w miniblink.bin, LED stops blinking, and flash is written
2015-02-04T12:52:26 < qyx_> and how is pl2303 connected to stm32
2015-02-04T12:52:39 < jpa-> how do you run your app? reboot without boot0 or run from bootloader?
2015-02-04T12:53:06 < thesame> my boot0 and boot1 are zeroes when I run app and when I flash
2015-02-04T12:53:21 < jpa-> then how do you get into bootloader at all?
2015-02-04T12:53:52 < thesame> that's what I'm asking here :)
2015-02-04T12:54:15 < thesame> why does flashing works?
2015-02-04T12:54:23 < qyx_> 11:52 < qyx_> and how is pl2303 connected to stm32
2015-02-04T12:54:37 < qyx_> stm32flash lists a feature "GPIO signalling to enter bootloader mode (hardware dependent) "
2015-02-04T12:54:59 < jpa-> yeah, it can do that if you connect RTS to BOOT0 & reset or something
2015-02-04T12:55:48 < jpa-> but if your boot0 is always connected to ground like you say, i can't see how it could possibly get into bootloader
2015-02-04T12:56:31 < thesame> I don't have a schematic of the board, but I think pl2303 is connected in some obvious way. I can closely look at traces to make sure.
2015-02-04T12:56:33 < thesame> What's RTS and how do I check if it's connected to BOOT0?
2015-02-04T12:56:52 < thesame> ah, it's rs232 line
2015-02-04T12:57:10 < jpa-> which board is it?
2015-02-04T12:58:25 < thesame> http://www.aliexpress.com/item/ARM-Cortex-M3-mini-stm32-stm32F103RBT6-Cortex-development-board-72MHz-128KFlash-20KRAM/1611212856.html this one
2015-02-04T12:59:36 < jpa-> why would you buy that instead of discovery? no debugger and no schematic :D
2015-02-04T12:59:38 < qyx_> why did you buy a development board without schematic?
2015-02-04T13:00:53 < thesame> 'cause I'm an idiot, obviously
2015-02-04T13:01:17 < jpa-> but yeah, probably it has the pl2303 lines hooked up to boot0 and reset
2015-02-04T13:01:25 < jpa-> quite smart actually, if you want to flash via serial

2015-02-04T18:32:01 < jpa-> karlp: do you know if the DWT -> ITM channel mapping is specified somewhere or varies from processor to processor? e.g. program counter seems to be trace port 0x17, but i can't find where this is specified
2015-02-04T18:33:51 < karlp> depends who wrote it there.
2015-02-04T18:34:05 < karlp> it doesn't have to be itm stimulus port 17,
2015-02-04T18:34:17 < karlp> but it might be dwt trace packet type 17, I don't know those off the top of my head
2015-02-04T18:34:30 < karlp> if you're just mixing that up in the decoding?
2015-02-04T18:35:05 < karlp> the only "standard" I've seen is that 0 is used as console, and 31 is used for "rtos profiling"
2015-02-04T18:35:22 < jpa-> i mean when i enable DWT PC sampling
2015-02-04T18:35:44 < jpa-> similarly i'm going to enable DWT exception info and it is going to be some random id
2015-02-04T18:36:11 < jpa-> not sure if i'm mixing something up or not
2015-02-04T18:36:12 < dongs> http://imgur.com/qoF1E65 found what zyp has been busy with (might be nsfw)
2015-02-04T18:36:32 < Steffanx> im the guy in the front.
2015-02-04T18:36:43 < dongs> haha
2015-02-04T18:37:48 < karlp> what did you use to "enable dwt pc sampling"
2015-02-04T18:37:50 < jpa-> err yeah, i'm messing up something atleast; 0x17 has bit 2 set, which is normally 0 for SWIT (like the manual print) packets
2015-02-04T18:38:08 < karlp> if you do that, it comes out as a "this is a dwt sample packet" not an ITM user trace port packet
2015-02-04T18:38:16 < karlp> what decoding tool are you using?
2015-02-04T18:38:25 < jpa-> nothing, i'm going to write a sigrok decoder
2015-02-04T18:38:29 < karlp> the one in oocd/contrib works with a couple of patches I submitted,

2015-02-04T18:38:44 < karlp> there's a dude, hrm, zapb iirc, he has a nice lib for doing it too
2015-02-04T18:39:03 < karlp> the oocd one is pretty complete too, works well
2015-02-04T18:39:13 < jpa-> apparently i'm missing the docs for dwt sample packet encoding
2015-02-04T18:40:08 < karlp> it's all in the arm docs, adiv5 iirc

2015-02-04T18:40:58 < karlp> hrm, no, not that one,
2015-02-04T18:40:59 < jpa-> require registration or something?

2015-02-04T18:42:09 < jpa-> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0314h/Chdcicdb.html   this is what i've been looking at so far
2015-02-04T18:42:14 < karlp> itmdump.c says it's all in armv7m ref manual
2015-02-04T18:42:46 < jpa-> i have armv7-m architecture reference manual but can't find it there
2015-02-04T18:43:36 < karlp> appendix D, page 931 onwards in my copy
2015-02-04T18:44:05 < jpa-> someone has done appendectomy on my copy
2015-02-04T18:44:42 < karlp> this is: "ARM DDI 0403Derrata 2010_Q3 (ID100710)"
2015-02-04T18:45:13 < jpa-> could you upload your copy somewhere?
2015-02-04T18:45:23 < karlp> sure, one tick
2015-02-04T18:46:33 < jpa-> i'm hoping to capture the SWO stuff with logic analyzer, and then being able to easily correlate external stuff to what happens inside the processor
2015-02-04T18:46:44 < karlp> yeah, that would be sexy
2015-02-04T18:47:00 < karlp> then you can make a groovy debugger with a shunt resistor and do power profiling too :)
2015-02-04T18:47:08 < jpa-> should be pretty trivial also, only need to write a bit of python for sigrok
2015-02-04T18:47:16 < karlp> http://palmtree.beeroclock.net/~karlp/DDI0403D_arm_architecture_v7m_reference_manual_errata_markup_1_0.pdf
2015-02-04T18:47:38 < jpa-> no need to even make a groovy debugger, just a continuous capture usb scope should be enough :P
2015-02-04T18:48:07 < karlp> well, I meant it needs the hardware to caputre the power info at the same time.
2015-02-04T18:48:16 < karlp> you can then correlate power usage with code segments
2015-02-04T18:48:29 < jpa-> hardware = shunt resistor + scope input
2015-02-04T18:48:52 < jpa-> but yeah, lots of things possible

2015-02-04T18:58:24 < karlp> you can probably also do things like use sigkroks stacking to let it do manchester decoding for you first too,
2015-02-04T18:58:33 < karlp> so you can then potentially get faster tracing

2015-02-04T23:40:01 < johntramp> qyx_: ah :)  so it can be done!
2015-02-04T23:40:03 < bvernoux> there is not a mask to accept multiple addr ...
2015-02-04T23:40:17 < bvernoux> like in lot of MCU which are very basic for I2C especially in slave mode
2015-02-04T23:40:21 < kakeman> I change celsius to kelvin to get rid of one unnecessary signed type
2015-02-04T23:40:41 < johntramp> so that line in features is a lie?
2015-02-04T23:41:05 < bvernoux> yes there is OAR1 & OAR2
2015-02-04T23:42:09 < bvernoux> yes true i OAR1 or OAR2 match it is ok
2015-02-04T23:42:15 < bvernoux> so you can use 2 addr
2015-02-04T23:42:29 < johntramp> great :)
2015-02-04T23:42:55 < bvernoux> anywya I have never tested this strange mode ;)
2015-02-04T23:43:20 < bvernoux> as for my need I2C Slave is too limited especially to sniff the bus

2015-02-05T02:07:36 < Fleck> ?
2015-02-05T02:07:48 < dongs> t this time this data is not available for the xPico WiFi dealing with the throughput of the SPI interface. Currently the xPico WiFi released firmware does not have support for SPI bridging, but this is on the roadmap to be added to the product in the future. Please note, that many factors, and some of which are affected by the users application, will also determine throughput so a theoretical maximum has no value without taking this into context.
2015-02-05T02:07:54 < dongs> The latest xPico WiFi release, running (bi-directional TCP streaming data) against firmware version 1.3.0.1R4 , returned these numbers (bps) 602139 avg.

2015-02-05T07:38:47 < dongs> i think some of those had decent screens too
2015-02-05T07:38:53 < PeterM> i'd have probably gotten another macbook but noapple storesaround and couldnt be bothered waiting for delivery
2015-02-05T07:38:59 < dongs> heh
2015-02-05T07:39:09 < englishman> no
2015-02-05T07:39:19 < dongs> R2COM: did you know, VisualBasic is the langauge of choice for Zano coders
2015-02-05T07:39:38 < dongs> not pro enough
2015-02-05T07:39:41 < dongs> visual is what makes it pro
2015-02-05T07:39:52 < dongs> also
2015-02-05T07:40:06 < dongs> i found some new material for cleaning stencil/squeegee
2015-02-05T07:40:21 < dongs> before i was using cotton sheets and that stuff would leave strings of cotton in places
2015-02-05T07:40:35 < dongs> not to mention sometimes get stuck to sharp edges on stencil, like on sot89 cutouts
2015-02-05T07:41:01 < dongs> i went to a pcb place and peeked at the shit they used, they had some higher density cotton or osmething sheets, teh stuff works way better
2015-02-05T07:41:05 < dongs> so I stole a huge bag of them
2015-02-05T07:41:20 < dongs> R2COM: yeah to clean the stencil after use
2015-02-05T07:41:24 < dongs> yeah, that doesnt work
2015-02-05T07:41:36 < dongs> shit will disintegrate and leave mess evreytwhere
2015-02-05T07:42:58 < dongs> of course they're steel
2015-02-05T07:43:04 < PeterM> i wonder if scotch brite pads would be too harsh
2015-02-05T07:43:04 < dongs> i dont use water either,  i use flux cleanear
2015-02-05T07:43:08 < dongs> PeterM: yes definitely
2015-02-05T07:43:27 < dongs> well i dont have that laying around
2015-02-05T07:43:34 < dongs> and I already use flux cleaner for washing boards
2015-02-05T07:43:47 < englishman> tried kimwipes?
2015-02-05T07:43:56 < dongs> R2COM: i bet you drink it too

2015-02-05T09:04:53 < elektrinis> we have a discussion at work about OSes
2015-02-05T09:05:12 < elektrinis> is freertos anaging sleep states?
2015-02-05T09:05:16 < elektrinis> *managing
2015-02-05T09:06:00 < elektrinis> guys insist on not using OS, but it takes so much time to write and debug scheduler, sleep management, etc
2015-02-05T09:16:40 < dongs> why do you need to manage sleep states
2015-02-05T09:16:43 < dongs> just wfi() in stuff
2015-02-05T09:19:10 < elektrinis> I myself am not a developer, but they say me:
2015-02-05T09:19:31 < elektrinis> we need a deep sleep, and it somehow need to reset the mcu when it is awake

2015-02-05T09:25:58 < elektrinis> ok
2015-02-05T09:26:33 < Roklobsta> elektrinis: it should take one competent guy to make a simple enough scheduler and test it.
2015-02-05T09:26:55 < Roklobsta> elektrinis: it should take one competent guy 5 days to make a simple enough scheduler and test it.
2015-02-05T09:27:04 < Roklobsta> by that I mean 35 hours
2015-02-05T09:27:25 < elektrinis> ok. so far it took over 35 days

2015-02-05T09:27:48 < dongs> using gcc??????????
2015-02-05T09:28:07 < elektrinis> just scheduler
2015-02-05T09:28:19 < Roklobsta> i mucked around for a few weeks worth of evenings 2 years ago and got a nice schduler going in AVR
2015-02-05T09:28:21 < qyx_> wut
2015-02-05T09:28:34 < dongs> you need to fire whoever is wasting time
2015-02-05T09:28:35 < qyx_> steal freertos
2015-02-05T09:28:35 < elektrinis> there is lots of thing happening
2015-02-05T09:28:36 < qyx_> i mean use
2015-02-05T09:28:46 < dongs> i mean, fuck, there's even cmsis rtos header you can just fucking use  that
2015-02-05T09:28:49 < dongs> and add line 20 lines of glue
2015-02-05T09:28:50 < elektrinis> dongs, looking into it
2015-02-05T09:29:02 < Roklobsta> premeptive with so called IO signals and yielding too.
2015-02-05T09:30:19 < Roklobsta> but preemptive schduler seems a little silly on 16MHz 8bit mcu.
2015-02-05T09:31:09 < elektrinis> i'm talking about stm32L
2015-02-05T09:31:23 < Roklobsta> yeah well it'll piss it in.
2015-02-05T09:31:55 < Roklobsta> the one i did put the cpu to sleep in the idle task.
2015-02-05T09:32:55 < Roklobsta> anyway it's not hard conceptually or to implement.
2015-02-05T09:34:06 < Roklobsta> real undergrad stuff which i think most undergrads now never get to do.  it's all java and python and CSS and HTML.
2015-02-05T09:34:10 < elektrinis> what about freertos, is it easier to use OS instead of writing your own scheduler
2015-02-05T09:35:06 < Roklobsta> elektrinis: i decided to do my own scheduler as I figured it'd take me the same time to write one from scratch and really understand what is going on vs trying to learn what someone else did,.
2015-02-05T09:35:52 < Roklobsta> elektrinis: you can use freertos and treat it like a black box and cross your fingers everything will be OK.
2015-02-05T09:36:23 < Roklobsta> though i'd say freertos is mature enough to Just Work.
2015-02-05T09:36:29 < elektrinis> do you have prctice with freertos?
2015-02-05T09:36:32 < Roklobsta> no
2015-02-05T09:36:35 < elektrinis> ok
2015-02-05T09:36:44 < qyx_> i used in once on avr
2015-02-05T09:36:45 < dongs> ive seen just enough freertos to never want to use it
2015-02-05T09:36:45 < elektrinis> would like a comment from someone who does
2015-02-05T09:36:46 < qyx_> it worked
2015-02-05T09:36:47 < dongs> shit looking API
2015-02-05T09:36:54 < dongs> ugly syntax
2015-02-05T09:37:04 < Roklobsta> i lost interest after i got my own working

2015-02-05T09:37:11 < qyx_> but the code is good quality
2015-02-05T09:37:15 < qyx_> dongs: tnats not true
2015-02-05T09:37:22 < dongs> qyx, it has files in million folders
2015-02-05T09:37:30 < dongs> that only work with a makemanfile
2015-02-05T09:37:35 < qyx_> i was surprised how much compilers and ides and things it supports
2015-02-05T09:37:53 < qyx_> no again, you can pick the ones you need, it is like 10 files
2015-02-05T09:37:55 < Roklobsta> gcc is all you need.
2015-02-05T09:38:38 < Roklobsta> elektrinis: just make sure your stack allocation is big enough for each task.
2015-02-05T09:38:43 < qyx_> there are keyi demos if you want
2015-02-05T09:38:45 < Roklobsta> or you'll be sorry.
2015-02-05T09:39:22 < Roklobsta> don't use heaps. etc etc etc
2015-02-05T09:39:32 < qyx_> why
2015-02-05T09:39:46 < Roklobsta> malloc in embedded is the devil
2015-02-05T09:39:52 < qyx_> again, why
2015-02-05T09:39:58 < qyx_> it depends
2015-02-05T09:40:26 < PaulFertser> Roklobsta: I've used freertos on atmega128 in preemptive mode, and it served fine for the purpose.
2015-02-05T09:40:31 < elektrinis> our projects does not let us 'allocate big enoug'
2015-02-05T09:40:31 < akaWolf> yeah
2015-02-05T09:40:37 < qyx_> and even some guidelines allow it during initialization
2015-02-05T09:40:44 < elektrinis> we need to be certain, as it is mission-critical application
2015-02-05T09:40:50 < akaWolf> not find eny evil in the dinamic allocatin and de- of memory
2015-02-05T09:40:51 < Roklobsta> the embedded systems I have done I have always made sure i know how much i need to allocate statically for fifo's/buffers etc and avoided local vars as much as possible.
2015-02-05T09:41:17 < akaWolf> global vars is a bad style
2015-02-05T09:41:34 < elektrinis> why malloc is bad?
2015-02-05T09:41:53 < PaulFertser> elektrinis: freertos provides means to check the free space on stack of each task, use that runtime to be sure you're not too close to the edge.

2015-02-05T09:42:07 < Roklobsta> akaWolf: small embedded systems it's not so bad and makes debugging anoying bugs easy
2015-02-05T09:42:40 < PaulFertser> Global vars should be avoided anyway. If it's a static local var, ok, makes sense, as it's predictable.
2015-02-05T09:43:01 < Roklobsta> i am just saying with limited resources you should know what your upper limits are an't don't rely on stack checking to get you by and prying that malloc doesn't fail at some point.
2015-02-05T09:43:32 < qyx_> Roklobsta: you just need to use your brain
2015-02-05T09:43:36 < PaulFertser> elektrinis: malloc is not predictable, and you don't know when you're going to get memory fragmentation etc. Also, on small systems malloc is usually using a very simple algorithm.
2015-02-05T09:43:41 < Roklobsta> PaulFertser: yes i should clarify yes static local vars
2015-02-05T09:43:53 < Roklobsta> qyx_: easier said than done.
2015-02-05T09:44:03 < qyx_> wut
2015-02-05T09:44:28 < PaulFertser> Roklobsta: it's not always easy to estimate the needed stack space per task, imho, how do you approach that?
2015-02-05T09:44:40 < Roklobsta> embedded systems can get complex very quickly at runtime, weird bugs can be a shit to track down, especiually with failing units in the field and a boss putting the flamethrower to you.
2015-02-05T09:45:05 < elektrinis> :)
2015-02-05T09:45:18 < elektrinis> i'm putting a flamethrower now
2015-02-05T09:45:45 < elektrinis> because omg, such silly bugs
2015-02-05T09:45:46 < qyx_> if you look up some mission critical guidelines, there is usually stated that dynamic allocation must be avoided at runtime, but not at system initialization
2015-02-05T09:45:50 < Roklobsta> trying to recreate the conditions of a failing unit in the field is very hard to do in the lab .
2015-02-05T09:45:55 < qyx_> even freertos use heap to create tasks initially
2015-02-05T09:46:43 < Roklobsta> i am just saying, understand and enforce the bounds of you applications so you don't run out of resources at runtime
2015-02-05T09:47:04 < qyx_> yes, i was referring to it by

2015-02-05T10:17:04 < dongs> ffffuuuuuuuuuuram
2015-02-05T10:17:34 < Roklobsta> Industrial CF cards from Western Digital and Cactus don't suffer this problem due to built in caps and firmware to deal with it.
2015-02-05T10:18:21 < dongs> orly?
2015-02-05T10:18:25 < dongs> how about not making brownouts in the first place
2015-02-05T10:18:28 < Roklobsta> a CF that fails during a write is a CF card that never comes back.
2015-02-05T10:18:36 < qyx_> so on the first place you are talking about determinism
2015-02-05T10:18:36 < dongs> surely relying on a fucking card to do it for youis fail
2015-02-05T10:18:47 < dongs> this guy is just trollin R2COM style
2015-02-05T10:18:51 < Roklobsta> dongs: you can't never think of all the ways shit can happen.
2015-02-05T10:18:52 < qyx_> and then you are fixing nondeterminisim from shitty cards and shitty filesystems with caps
2015-02-05T10:18:54 < dongs> its like altium vs orcad discussion
2015-02-05T10:18:56 < Roklobsta> especially on a mine site.
2015-02-05T10:19:49 < qyx_> there are things like filesystems designed for flash devices if you are dealing with random brownouts
2015-02-05T10:20:01 < qyx_> with native transaction safety
2015-02-05T10:20:04 < PaulFertser> Roklobsta: an external watchdog should handle that though? Or is your point that it must be connected in a way to power-cycle the target completely? I can see how that makes sense...
2015-02-05T10:20:25 < Roklobsta> qyx_: you don't understand, a failed CF card is one that has to be thrown in the trash.
2015-02-05T10:20:48 < Roklobsta> and making is fail is as asimple as powering off while the internal SoC is still writing to the memory cells.
2015-02-05T10:21:06 < Roklobsta> is = it
2015-02-05T10:21:16 < qyx_> "making it fail" is what?
2015-02-05T10:21:20 < qyx_> corrupted fileysystem?
2015-02-05T10:21:25 < qyx_> corrupted ftl?
2015-02-05T10:21:35 < qyx_> resulted from bad firmware on the cf itself?
2015-02-05T10:21:57 < Roklobsta> like never ever responds to the MCU ever again.
2015-02-05T10:22:14 < PaulFertser> Not even after power-cycle?
2015-02-05T10:22:15 < Roklobsta> it's the reason wjhy cameras with CF have a warning to power off before removing the card
2015-02-05T10:22:17 < qyx_> interesting, then i agree
2015-02-05T10:22:27 < PaulFertser> Man, that must be some really shitty CF you had there.
2015-02-05T10:23:29 < Roklobsta> well, it took many years before Silicon Image and Cactus came out with cards immune to this
2015-02-05T10:24:00 < qyx_> they used malloc for suer
2015-02-05T10:24:03 < PaulFertser> :D

2015-02-05T10:39:52 < dongs> so far everything I did was nicely aligned with that

2015-02-05T10:40:52 < dongs> while routing

2015-02-05T15:21:45 < jpa-> which optimization level? do you remember to pass -O flags to linker stage?

2015-02-05T15:23:42 < akaWolf> nice question, it's not mine found, but my known, so I dont know. as I know, he tried both optimization: for size, and for speed.
2015-02-05T15:24:46 < akaWolf> I will ask him.

2015-02-05T20:18:48 < jpa-> karlp: making progress: http://koti.kapsi.fi/jpa/stuff/pix/sigrok_swo.png
2015-02-05T20:19:40 < Laurenceb> arg
2015-02-05T20:19:48 < Laurenceb> maybe not.. this makes my head hurt
2015-02-05T20:20:00 < bvernoux> jpa-: ha nice !!
2015-02-05T20:20:09 < Laurenceb> i must have broken the NVIC
2015-02-05T20:20:12 < bvernoux> jpa-: sigrok is really amazing
2015-02-05T20:21:20 < Steffanx> You're using a logic analyzer to decode the swo output jpa-? If so, nice nice :)
2015-02-05T20:21:26 < Laurenceb> very nice
2015-02-05T20:21:27 < jpa-> Steffanx: yeah
2015-02-05T20:21:53 < jpa-> need better logic analyzer though; fills my DSO Quad buffer in less than a second - already ordered some cheap FX2 based one
2015-02-05T20:22:11 < Laurenceb> cool
2015-02-05T20:22:33 < Laurenceb> anyone got any ideas why gdb isnt aware of stm32 registers?
2015-02-05T20:22:49 < Laurenceb> "No symbol "NVIC" in current context."
2015-02-05T20:22:59 < bvernoux> Laurenceb: use Em:Blocks
2015-02-05T20:23:05 < bvernoux> ;)
2015-02-05T20:23:08 < Laurenceb> wtf is that?
2015-02-05T20:23:14 < bvernoux> it's all in one
2015-02-05T20:23:19 < bvernoux> IDE+GDB+Debugger
2015-02-05T20:23:21 < PaulFertser> jpa-: do you think UART-style SWO output can be captured by a regular UART? Are you decoding Manchester here?
2015-02-05T20:23:26 < Laurenceb> oh
2015-02-05T20:23:28 < bvernoux> and access to periperhals for each ARM MCU
2015-02-05T20:23:41 < bvernoux> and NOT based on Eclipse ;)
2015-02-05T20:23:42 < Laurenceb> well i have stuff setup
2015-02-05T20:23:53 < Laurenceb> i just need to work out why EXTI0 isnt triggering
2015-02-05T20:24:09 < Laurenceb> but that involves reading the NVIC registers
2015-02-05T20:24:11 < Steffanx> your other exti's are triggering Laurenceb?
2015-02-05T20:24:13 < Laurenceb> yes
2015-02-05T20:24:20 < Laurenceb> i have 2 others that work fine
2015-02-05T20:24:27 < Laurenceb> only EXTI0 fails
2015-02-05T20:24:47 < jpa-> PaulFertser: uart style can be captured by regular uart, but most cheap usb-rs232 converters only do some ridiculous 1Mbps
2015-02-05T20:25:14 < jpa-> PaulFertser: i'm not decoding manchester, because it would require more logic analyzer BW than uart does
2015-02-05T20:25:21 < bvernoux> Laurenceb: if you are using Eclipse + GDB for debug you can use plugin to access NVIC and specific register to STM32Fx
2015-02-05T20:25:32 < PaulFertser> jpa-: I see, thank you. And yes, the screenshot looks very impressive.
2015-02-05T20:25:46 < Laurenceb> yeah but im not
2015-02-05T20:25:53 < Laurenceb> i only want one thing
2015-02-05T20:25:56 < Laurenceb> to fix exti0
2015-02-05T20:26:11 < PaulFertser> Laurenceb: if you compile with -ggdb3 (or -g3) you'll have all macro expandable, so "p/x GPIOA->IDR" will work.
2015-02-05T20:26:23 < Laurenceb> i am compiling with -g3
2015-02-05T20:26:30 < Laurenceb> no GPIOA to be seen
2015-02-05T20:26:32 < bvernoux> Laurenceb: and -O0
2015-02-05T20:26:35 < bvernoux> ?
2015-02-05T20:26:36 < Laurenceb> oh
2015-02-05T20:26:40 < Laurenceb> no i didnt try that
2015-02-05T20:26:49 < bvernoux> -O2 remove to much symbols
2015-02-05T20:27:02 < Laurenceb> actually no
2015-02-05T20:27:09 < Laurenceb> i used -Og
2015-02-05T20:27:20 < bvernoux> -O0 -g3 is good
2015-02-05T20:27:26 < bvernoux> C code will match ASM
2015-02-05T20:27:31 < bvernoux> and structure could be seen too
2015-02-05T20:27:51 < jpa-> PaulFertser: i did do initial testing with usb-rs232 and it is very easy to set up, like "why haven't i done this before".. definitely fast enough to get e.g. exception trace and short software messages
2015-02-05T20:28:16 < Laurenceb> ive had hardfaults from -O0 before
2015-02-05T20:28:21 < Laurenceb> but ill try it i guess
2015-02-05T20:28:51 < bvernoux> personally I use Semi Hosting(SWD debug) for exception
2015-02-05T20:28:57 < bvernoux> and it work fine with Em::Blocks
2015-02-05T20:29:05 < bvernoux> it display all in a window natively
2015-02-05T20:29:13 < bvernoux> OpenOCD support it too IIRC
2015-02-05T20:29:14 < PaulFertser> bvernoux: nah, -O doesn't remove any symblos.
2015-02-05T20:29:36 < PaulFertser> Laurenceb: are you linking with -g3 too?
2015-02-05T20:29:37 < bvernoux> PaulFertser: yes but it optimize too much code to have access to variables and structure sometime
2015-02-05T20:29:53 < bvernoux> so at end -O2 code is not C code
2015-02-05T20:29:54 < PaulFertser> bvernoux: yes, debugging optimized code is complicated sometimes.
2015-02-05T20:30:15 < bvernoux> anyway I read ARM asm code since lot of time now so I debug it but it's harder
2015-02-05T20:30:29 < Laurenceb> yes
2015-02-05T20:30:34 < bvernoux> the worst case is when we check a variable it display bad value ;)
2015-02-05T20:30:36 < Laurenceb> hmm
2015-02-05T20:30:55 < Laurenceb> I've found another software triggered project that accesses the NVIc directly
2015-02-05T20:30:58 < Laurenceb> i will try that
2015-02-05T20:33:02 < jpa-> bvernoux: isn't semihosting quite slow for interrupt tracing?
2015-02-05T20:33:35 < bvernoux> yes
2015-02-05T20:33:44 < bvernoux> it depends on how much data you send
2015-02-05T20:33:52 < bvernoux> anyway I use it for crash ;)
2015-02-05T20:34:21 < bvernoux> mainly hard fault with full log like on linux ;)
2015-02-05T20:34:51 < bvernoux> next step is to add MPU support to catch bug before like access to addr 0 or jump to 0
2015-02-05T20:35:00 < bvernoux> as it's hard to trace back with an OS ...
2015-02-05T20:35:26 < jpa-> ah yeah
2015-02-05T20:35:30 < bvernoux> and also protect stacks from overflow/underflow before it's too late ;)
2015-02-05T20:41:33 < Tectu> jpa-, spa weekend?

2015-02-05T23:49:44 < kakeman> that gives power thru like.. 4megawatts
2015-02-05T23:49:55 < kakeman> you can do stuff with that
2015-02-05T23:50:44 < kakeman> run a locomotive motor
2015-02-05T23:51:25 < qyx_> beaky should design a locomotive controller with F7
2015-02-05T23:51:34 < kakeman> I guess they have transformers in locomotives, 30kv or so lines straight to motor do not sound ok

2015-02-06T09:28:15 < dongs> you can have all teh obnoxious voltages out of 1 chip
2015-02-06T09:28:56 < PeterM> im tempted to try layit out decently on 2L
2015-02-06T09:29:10 < dongs> its probably not awful sinec it exists
2015-02-06T09:29:22 < dongs> those things are usually made for a purpose
2015-02-06T09:29:29 < dongs> and if there's a evalboard, they already have a ready to go layout for that
2015-02-06T09:29:39 < dongs> should be at least an appnote or something with recommended shit if it isnt in datasheet already
2015-02-06T09:29:53 < PeterM> yeah, DS shows topside layout
2015-02-06T09:30:00 < PeterM> looks pretty easy actually
2015-02-06T09:31:25 < PeterM> that and richtek usually know that you dont want to use a 6L pcb just to route a DC/DC unlike LT
2015-02-06T09:31:32 < dongs> HEH
2015-02-06T09:32:40 < dongs> clearly for old stuff tho, no 1.2V core

2015-02-06T16:41:45 < PaulFertser> Got SWO data on 2MHz simply by connecting SWO to the second FT2232H channel.
2015-02-06T16:42:40 < PaulFertser> And it's the maximum frequency for stlink, and I assume if most people are happy with stlink, that means ft2232h will work as well for them.
2015-02-06T16:46:11 < karlp> cool :)
2015-02-06T16:46:31 < karlp> iirc from what ntfreak was saying, newer stlinks have been upgraded to 4Mhz

2015-02-06T17:54:06 < PaulFertser> karlp: I think for the microcontroller users the most interesting features would be: 1. printf via ITM. 2. non-intrusive profiling for the whole application with DWT.
2015-02-06T17:54:57 < karlp> I very muhc like printing values to other channels,
2015-02-06T17:55:35 < PaulFertser> karlp: what's your usecase? Not that I promise I'll work on that, but who knows, I'd like to have that in mind anyway.
2015-02-06T17:55:43 < Fleck> anyone here with stm32F29i-Discovery board? I have sometimes green screen after reset, anyone have had the same problem?
2015-02-06T17:56:33 < trepidaciousMBR> Fleck: I had one of those, but I didn't really run the demo much. When I did it seemed fine, then I replaced the firmware :)
2015-02-06T17:57:20 < karlp> one the one I was doing most recently, I used itm 2 and itm3 to mirror the uart RX traffic I was receiving on two different uarts, itm0 for some text printf sttylee, another itm with dwt-cyclecount to manually count a couple of routines, (wasn't motivated enough to automatically enable timing stuff)
2015-02-06T17:57:49 < karlp> and another channel was looking at a gdb variable for channel selection, and streaming out the adc readings for that channel
2015-02-06T17:58:29 < karlp> I found it great to use multiple channels to automatically tag output, instead of havingt to printf("main: blah")
2015-02-06T17:58:41 < karlp> I just had print(channel, "blah"
2015-02-06T17:58:53 < Fleck> trepidaciousMBR: http://im9.eu/picture/img-20150206-175642 << screen ok, http://im9.eu/picture/img-20150206-175638 << screen not ok, happens just by pressing reset, sometimes ok, sometimes not ok!
2015-02-06T17:59:04 < karlp> (wasn't always printf, because that overhead is taken regardless of whether the stim port is on or off), but the idea is the same
2015-02-06T17:59:52 < karlp> PaulFertser: I was then grepping the decoded otuput to (grossly) filter a certain channel's values to file, and feeding that to kst2 or something similar for live graphing of the values.
2015-02-06T17:59:57 < trepidaciousMBR> Fleck: Weird :) I could be being too harsh, but I would put it down to half-baked STM demo code in all likelihood...

2015-02-06T18:00:26 < trepidaciousMBR> Fleck: My general impression of STM (demo) code is that it works, kind of, as long as nothing goes wrong, but you shouldn't expect any more than that
2015-02-06T18:01:20 < trepidaciousMBR> Fleck: I generally use ChibiOS or just start from scratch based on datasheet and ST periph lib code, I don't really like ST code at all.
2015-02-06T18:02:21 < Fleck> bugz everywhere? :D
2015-02-06T18:02:50 < trepidaciousMBR> Fleck: Pretty much, but probably other people here will have a more accurate impression than me, as I say I've not really used ST code very much

2015-02-06T18:06:17 < PaulFertser> karlp: I mean even without SWO.
2015-02-06T18:06:45 < karlp> dwt writes the profiling to the traceport
2015-02-06T18:06:52 < karlp> no swo, no profiling.
2015-02-06T18:07:54 < PaulFertser> karlp: what about "external PC sampling" DWT_PCSR?
2015-02-06T18:08:34 < karlp> well yeah, there's that
2015-02-06T18:08:44 < PaulFertser> But not in STM32?
2015-02-06T18:08:47 < PaulFertser> Or?
2015-02-06T18:08:51 < karlp> but it's going to be oddly timed based on how rliably you can poll that register
2015-02-06T18:09:18 < PaulFertser> What did you mean by "manually count a couple of routines"?
2015-02-06T18:09:19 < karlp> it's never going to be even close to as nice as the proper clock sampling profiling you get, but yeah, it would also work.
2015-02-06T18:09:34 < PaulFertser> Still better than halt/resume cycle that is implemented currently.
2015-02-06T18:09:52 < PaulFertser> And that halt/resume cycle actually works nicely for most purposes afaict.
2015-02-06T18:09:57 < karlp> oh, doing uint32_t before = DWT_CYCCNT; isr_stuff(); itm_write(STIM_TIMING_ISRxxx, DWT_CYCCOUNT-before);
2015-02-06T18:10:07 < PaulFertser> It's statistics after all. Do it long enough, you'll have it accurate enough.
2015-02-06T18:10:41 < karlp> I'd rather just do it nicely using trace, get more people used to the things they can have if they start using trace
2015-02-06T18:10:56 < PaulFertser> But not on Cortex-M0, not if the pin is not routed etc.
2015-02-06T18:11:01 < karlp> instead of a slightly better version just so you don't have to use the features on the core.
2015-02-06T18:11:13 < PaulFertser> I agree it would be nice to actually make use of the facilities provided.

2015-02-06T18:40:01 < PaulFertser> karlp: I really wonder if proper profiling is any better than halt/resume fake profiling because the statistics adds up. But instruction tracing can be awesome in understanding what went wrong during the particular run. So I guess instruction tracing is more important.
2015-02-06T18:40:28 < karlp> the proper profiling gives you a statisticly significant result far far faster.
2015-02-06T18:40:43 < PaulFertser> Yes, faster, agreed.
2015-02-06T18:40:47 < karlp> I'm not actually talking about the actual instruction tracing, that's only on the ETM stuff
2015-02-06T18:40:48 < Laurenceb> http://pastie.org/9892517 holy shit
2015-02-06T18:41:03 < karlp> so that's hardly ever broken out on low end, and requires even more tools

2015-02-06T18:41:23 < karlp> I just meant the one that puts a tap on the PC at various notches to get statisticcal sampling
2015-02-06T18:41:30 < PaulFertser> Yes, but that would be interesting.
2015-02-06T18:41:40 < karlp> oh yeah, it would be :)

2015-02-06T19:14:13 < Taxman> does anyone use the internal voltage reference for adc?
2015-02-06T19:14:27 < Laurenceb> wut
2015-02-06T19:14:34 < Laurenceb> i didnt know there was one lol
2015-02-06T19:14:51 < kakeman> if possible, if there is one
2015-02-06T19:15:17 < kakeman> and no need for extra precision
2015-02-06T19:15:37 < PaulFertser> Taxman: there's no internal voltage reference, but there's an internal channel that's factory calibrated iirc.
2015-02-06T19:16:02 < kakeman> reference channel?
2015-02-06T19:16:04 < PaulFertser> So it's a reference of sorts.
2015-02-06T19:16:06 < PaulFertser> Yes.
2015-02-06T19:16:16 < PaulFertser> VREFINT
2015-02-06T19:16:34 < Taxman> it is a reference (f429) that is fed to the adc input mux
2015-02-06T19:16:50 < Taxman> but it is not the reference for the adc
2015-02-06T19:18:35 < PaulFertser> Yes.
2015-02-06T19:18:41 < kakeman> if you need precise reference voltage just power your mcu from reference voltage
2015-02-06T19:19:08 < Taxman> the whole cpu? ;)
2015-02-06T19:19:16 < Taxman> i assume you mean avdd
2015-02-06T19:19:26 < PaulFertser> Taxman: but you can measure that channel, get the calibrated value from a particular memory address, and use that to scale your other channels.
2015-02-06T19:19:54 < PaulFertser> Bigger packages allow to connect separate reference voltage.
2015-02-06T19:19:59 < kakeman> Taxman: or that way
2015-02-06T19:20:05 < PaulFertser> But it can't be too different from Vcc.
2015-02-06T19:20:20 < Taxman> PaulFertser: Have you tried it? i assume the precision is ways lower than a external reference source

2015-02-06T19:21:08 < kakeman> and what it causes if avdd goes up first

2015-02-06T19:21:55 < karlp> I use it to compensate for temp and voltage dips from power supply noise, works very well.
2015-02-06T19:22:02 < PaulFertser> Taxman: why do you think it's too inaccurate?
2015-02-06T19:22:03 < Laurenceb> kakeman: AVDD!=VDD causes issues
2015-02-06T19:22:17 < Laurenceb> in my experience the processor wont boot
2015-02-06T19:22:50 < gxti> you can get a voltage supervisor ic to hold it in reset until both are stable
2015-02-06T19:22:59 < karlp> Taxman: I got substantially better adc results after using the internal ref and temp sensor to calibrate my adc readings.
2015-02-06T19:23:11 < Laurenceb> i used a couple of transistors
2015-02-06T19:23:19 < Taxman> PaulFertser: It is only around 1.2V. so quantization errors should scale up neraly by factor 3 when avdd=3.3V, isn't it?
2015-02-06T19:23:20 < kakeman> just keeping processor reset until both rails are up will do?
2015-02-06T19:23:24 < gxti> although instead of a LDO you should use a proper voltage reference if you're going that route
2015-02-06T19:23:34 < gxti> otherwise not much point
2015-02-06T19:23:37 < Laurenceb> kakeman: maybe
2015-02-06T19:23:44 < Laurenceb> but it violated datasheet iirc

2015-02-06T19:24:44 < karlp> Taxman: what are you talking quantization errors for? there's no change, you're always using 3.3v?
2015-02-06T19:25:00 < Taxman> yes i am always using 3.3V
2015-02-06T19:25:31 < PaulFertser> He means those 1.2V can't be measured with 12
2015-02-06T19:25:59 < PaulFertser> bit accuracy because it's not about the reference but 3x times smaller.
2015-02-06T19:26:00 < Taxman> i mean i measeure 1.2v with avref+=3.3 V
2015-02-06T19:26:18 < Taxman> this gives something around 4096/3
2015-02-06T19:26:22 < karlp> whatever man, if this is mission critical for you, you're going to need to suck it and see
2015-02-06T19:26:36 < Taxman> yeah
2015-02-06T19:26:42 < karlp> it was a substantial improvement for us over not calibrating to the internal ref.
2015-02-06T19:26:55 < Taxman> i need a reference for measuring external voltages
2015-02-06T19:27:13 < Taxman> 0-10V scaled down by a resistor divider
2015-02-06T19:27:17 < PaulFertser> Taxman: do I get it right that one's basically turning 12-bit ADC into 10-bit ADC when using Vrefint?
2015-02-06T19:27:21 < Taxman> to 0-3V
2015-02-06T19:27:49 < Laurenceb> depends what you mean by bits
2015-02-06T19:27:49 < Taxman> PaulFertser: Don't know it
2015-02-06T19:27:53 < karlp> PaulFertser: uwhat? you can't use the 1.2 as a reference, you can only measure the voltage of the ref as compared to be your avdd
2015-02-06T19:27:54 < gxti> you can get some bits back by oversampling
2015-02-06T19:28:10 < Laurenceb> for many applications distortion or offset isnt an issue
2015-02-06T19:28:20 < PaulFertser> gxti: but only if the input is noisy enough?
2015-02-06T19:28:24 < Laurenceb> AWGN is the problem
2015-02-06T19:28:35 < Taxman> the noise is not the problem, the accuracy of the results (with oversampling) is
2015-02-06T19:28:47 < gxti> PaulFertser: dunno how noisy it is, i've never done ADC stuff on STM32
2015-02-06T19:28:50 < PaulFertser> karlp: because you can't measure 1.2V accurately. Just imagine they'd use 0.1V as a bandgap reference :)
2015-02-06T19:29:03 < Laurenceb> if you want that sort of precision then you are going to have to work hard
2015-02-06T19:29:09 < PaulFertser> gxti: I mean for oversampling to work the input must have random noise added, right?
2015-02-06T19:29:11 < Taxman> PaulFertser: Exactly
2015-02-06T19:29:12 < Laurenceb> getting ~1lsb of noise is easy
2015-02-06T19:29:20 < Laurenceb> 1lsb of precision is very hard
2015-02-06T19:29:38 < karlp> PaulFertser: sure, so that's why I said, "doign it helps, your application may require more"
2015-02-06T19:29:44 < gxti> just 1 bit of noise is all that's needed, and i seriously doubt that stm32's adc is so amazeballs that it has no noise whatsoever :p
2015-02-06T19:29:49 < karlp> it's still 12bit,
2015-02-06T19:30:01 < karlp> so who cares, avr lets you use the 1.1 as a reference, but only has 10bit
2015-02-06T19:30:09 < karlp> comes out close enough
2015-02-06T19:30:11 < gxti> anyway, putting this much concern into a 12bit adc built into stm32 is a waste of time
2015-02-06T19:30:35 < gxti> if cutting ~ 1 bit of precision from your vref calibration is a problem then maybe you should be using an external adc.
2015-02-06T19:30:44 < Taxman> karlp: ANd that was a good solution. enough for a lot of applications
2015-02-06T19:31:20 < PaulFertser> Laurenceb: not too hard, just measure 4 times and average.
2015-02-06T19:31:22 < karlp> Taxman: what I'm saying is, so's the one you've got. if your appneeds more, listen to gxti's advice :)
2015-02-06T19:32:02 < Taxman> i wonder how much the accuracy (with oversampling) would be. 1mV? 10mV? more?
2015-02-06T19:32:27 < karlp> go and read up on how oversampling works
2015-02-06T19:32:28 < Taxman> when using vrefint for calib and temp sensor
2015-02-06T19:32:37 < karlp> can be as much as you want if you've got time and teh signal is stable
2015-02-06T19:32:40 < Taxman> the oversampling only cancels noise
2015-02-06T19:33:10 < Taxman> my problem is not noise, but temperature drifts ov avdd and vrefint

2015-02-06T19:38:40 < karlp> I don't assume vdda is anything in particular, the vrefint and temp tell me what vdda really is. good enough for guvmint work
2015-02-06T19:38:42 < gxti> measure vrefint across a range of temperatures, come up with a 1st or 2nd order correction based on that
2015-02-06T19:39:07 < karlp> or read the datasheet that says "it's linear, use the two values we gave you"
2015-02-06T19:39:16 < gxti> feels a little like overkill but on the other hand it's just software so no added unit cost

2015-02-07T02:56:42 < specing> englishman: ah thanks
2015-02-07T02:59:24 < Laurenceb_> has anyone come up with a way to calibrate LSI on F103?
2015-02-07T02:59:44 < Laurenceb_> the watchdog tolerance is too wide for me :-/
2015-02-07T03:06:44 < karlp> there's an appnote on calibrating hsi based on an external timer, or lsi,
2015-02-07T03:06:49 < karlp> it's probably relevant
2015-02-07T03:07:58 < Laurenceb_> ok
2015-02-07T03:08:07 < Laurenceb_> im guessing its using timer5 tho?
2015-02-07T03:08:13 < Laurenceb_> no timer5 on F103
2015-02-07T03:08:35 < Laurenceb_> "RVU:
2015-02-07T03:08:35 < Laurenceb_> Watchdog counter reload value update
2015-02-07T03:08:35 < Laurenceb_> This bit is set by hardware to indicate that an update of the reload value is ongoing"
2015-02-07T03:08:46 < Laurenceb_> lol i guess you could busy wait for that bit
2015-02-07T03:11:34 < Laurenceb_> or clock the RTC lulz
2015-02-07T03:11:40 < Laurenceb_> but im using the RTC
2015-02-07T03:14:30 < Laurenceb_> i guess a 10khz timer triggered DMA read would work
2015-02-07T03:15:06 < Laurenceb_> kind of silly.. but i guess it wont actually be that much code

2015-02-07T04:43:05 < zyp> dongs, what about systemd?

2015-02-07T04:46:03 < zyp> because a ton of shell scripts is the right way to handle startup, right
2015-02-07T04:48:32 < zyp> I'd guess that you love systemd just because it has all the old graybeard's panties in a bunch

2015-02-07T06:07:08 < GargantuaSauce_> it will be sensitive up to like....1200nm i think?
2015-02-07T06:07:16 < dongs> for all the effort you can just buy a surplus cmos imager from china

2015-02-07T10:12:59 < DrLuke> Basically, when I comment out that call to an empty function, my program runs normally. When I leave it in, it just stops at that point.
2015-02-07T10:14:06 < upgrdman> shouldnt int i be volatile?
2015-02-07T10:14:20 < upgrdman> err int a
2015-02-07T10:14:58 < DrLuke> Oh, that's just a remnant
2015-02-07T10:15:20 < upgrdman> also cleaner to do something like: for(volatile uint32_t i = 0; i < 100000; i++); .... no need for explicit nop
2015-02-07T10:16:19 < DrLuke> Yes, but what could cause my problem?
2015-02-07T10:17:23 < upgrdman> dont really know
2015-02-07T10:17:31 < upgrdman> i would debug and single step through it
2015-02-07T10:17:41 < DrLuke> I don't know how to do that
2015-02-07T10:17:51 < DrLuke> Is it a lot of effort?
2015-02-07T10:17:51 < upgrdman> well theres the problem :)
2015-02-07T10:17:58 < upgrdman> ever used gdb?
2015-02-07T10:18:01 < DrLuke> No
2015-02-07T10:18:04 < upgrdman> ok

2015-02-07T10:18:23 < upgrdman> good. i have notes that might help you.
2015-02-07T10:18:28 < dymk> does the HAL automatically set up a watchdog or something?
2015-02-07T10:18:44 < dymk> if I have an empty for loop like upgrdman's that is too long, the board just freezes

2015-02-07T10:19:05 < dymk> this is on the stm32f4 discovery board, btw
2015-02-07T10:19:14 < upgrdman> and my shitty gdb notes    http://www.farrellf.com/projects/hardware/2012-06-18_Hardware_Debugging_with_GDB_and_the_STM32F4/
2015-02-07T10:19:17 < jpa-> PaulFertser: AFAIK ETM will work over SWO also, but with limited speed; because SWO clk is at max HCLK, it'll take 10 cycles to send even shortest branch packet; but you can set ETM to block the CPU when buffer is full
2015-02-07T10:20:35 < DrLuke> upgrdman: Thank you, I will read that carefully
2015-02-07T10:20:47 < upgrdman> sure. good luck.
2015-02-07T10:21:01 < PaulFertser> jpa-: that sounds useful enough?
2015-02-07T10:21:09 < upgrdman> aside from getting the gdb server working and connecting to it, you debug just like regular pc programs
2015-02-07T10:21:24 < upgrdman> so youtube for "gdb" and there's tons of tutorials
2015-02-07T10:21:33 < DrLuke> Ah
2015-02-07T10:21:34 < jpa-> PaulFertser: yeah, for many purposes it is probably ok
2015-02-07T10:22:09 < jpa-> PaulFertser: i'll probably see about adding ETM decoding also, though at first only the packets and not the interpolation between the sample points
2015-02-07T10:23:10 < GargantuaSauce_> DrLuke: double check that the declaration of your function is identical to its implementation
2015-02-07T10:24:25 < DrLuke> GargantuaSauce_: It is
2015-02-07T10:24:28 < PaulFertser> jpa-: I thought Linaro folks are working on getting tracing to work meaningfully on cortex-a, but so far all I found was how they used proprietary arm tool with xml configs to decode the trace to a semi-useful assembly.
2015-02-07T10:24:35 < GargantuaSauce_> its kind of surprising how badly you can screw up without the compiler complaining too loudly, the result being a jump to an address on the stack or whatever
2015-02-07T10:24:45 < GargantuaSauce_> k well the debugger will probably reveal what's going on then
2015-02-07T10:25:46 < jpa-> PaulFertser: it seems that the packets themselves should be easy enough to follow manually.. they tell every conditional branch and can be set to tell also non-conditional calls, so basically just have to have disassembly open to know what happens between branch points
2015-02-07T10:28:03 < jpa-> PaulFertser: it seems that some cpus like LPCxxx have a RAM buffer for ETM, so that one could set it to keep a log of last 2k or so branches, and then check them once you are at a breakpoint
2015-02-07T10:31:42 < upgrdman> android doesn't have a built-in game engine huh?

2015-02-07T11:03:13 < upgrdman> hmm
2015-02-07T11:04:22 < upgrdman> DrLuke, i think the cost is causing something like HardFault which drops you into that infinite loop

2015-02-07T11:04:47 < DrLuke> how can an empty function do that :S
2015-02-07T11:04:55 < DrLuke> I doubt it, the program is really simple
2015-02-07T11:05:17 < upgrdman> iirc, by default, undefined ISRs are just while(1); loops
2015-02-07T11:05:41 < upgrdman> might try stepi to step by instruction instead of by line-of-code
2015-02-07T11:05:54 < upgrdman> to see what actual instruction cause the HardFault
2015-02-07T11:06:17 < upgrdman> might also be something like a linker script issue. e.g. stack setup wrong
2015-02-07T11:06:26 < DrLuke> upgrdman: It gets stuck running the following instruction: 100	in ../../cm3/vector.c
2015-02-07T11:06:34 < DrLuke> (as outputted by stepi)
2015-02-07T11:06:47 < upgrdman> what instructions were before that one
2015-02-07T11:08:03 < DrLuke> upgrdman: http://pastebin.com/pARjzgTh
2015-02-07T11:09:53 < upgrdman> ok
2015-02-07T11:10:06 < upgrdman> so right before the ISR, the cost is doing __memcpy_from_thumb ()
2015-02-07T11:10:23 < upgrdman> this makes me think there is a linker issue
2015-02-07T11:10:43 < upgrdman> perhaps stuff isn't stored where it should be
2015-02-07T11:10:47 < DrLuke> What is that memcpy good for?
2015-02-07T11:11:00 < upgrdman> but i don't know enough to be of much help there
2015-02-07T11:11:22 < upgrdman> memcpy copies memory. basically "copy n bytes from 0xFOO to 0xBAR"
2015-02-07T11:11:52 < upgrdman> maybe someone else here can help.
2015-02-07T11:12:10 < upgrdman> if not, try the stm forums, or, uh, does opencm3 have forums/irc/etc?
2015-02-07T11:12:37 < DrLuke> They have a channel on freenode

2015-02-07T11:44:59 < dongs> shit code
2015-02-07T11:45:10 < DrLuke> Very helpful
2015-02-07T11:45:50 < dongs> i see a shitload of horrible coding practices just in the part you pasted
2015-02-07T11:46:21 < DrLuke> Yeah, so instead of saying "shit code" you could actually tell me what is shit about it
2015-02-07T11:46:26 < DrLuke> instead you're just being a rude asshole
2015-02-07T11:46:34 < dongs> 1) bad indentation/spacing

2015-02-07T12:58:22 < Roklobsta> ada was going to be big then.
2015-02-07T13:00:35 < Roklobsta> be interesting to use it on stm32 class devices.

2015-02-07T15:04:53 < PaulFertser> DrLuke: "next" in gdb is done via single instruction stepping, so it's slow if there's much to do.
2015-02-07T15:05:10 < DrLuke> PaulFertser: I am using continue in this case
2015-02-07T15:05:29 < PaulFertser> DrLuke: continue shouldn't affect execution speed, no.
2015-02-07T15:05:39 < DrLuke> Hmm
2015-02-07T15:05:44 < DrLuke> something's broken...
2015-02-07T15:05:56 < Laurenceb_> using st-link?

2015-02-07T15:06:29 < DrLuke> openocd
2015-02-07T15:06:44 < DrLuke> it somehow seems to often get stuck when doing continue or finish
2015-02-07T15:06:52 < Laurenceb_> hmm
2015-02-07T15:06:57 < DrLuke> curiously, ISRs will continue to fire
2015-02-07T15:07:10 < DrLuke> since the DAC keeps outputting the waveform I want
2015-02-07T15:07:11 < Laurenceb_> that happens with st-link and texane
2015-02-07T15:07:16 < Laurenceb_> single step out of the isr
2015-02-07T15:08:25 < DrLuke> Laurenceb_:  There's quite a lot of upcoming ISRs before the code continues :P
2015-02-07T15:08:50 < DrLuke> maybe I should reduce the frequency for debugging
2015-02-07T15:14:48 < PaulFertser> DrLuke: with openocd continue does just this: sets all the breakpoints and lets the target run freely. There's also cortex_m maskisr (for low level adapters) but it shouldn't affect running, only stepping.
2015-02-07T15:15:42 < PaulFertser> DrLuke: are you using multi-arch gdb or arm-none-eabi-gdb? The latter might behave a little better. Also, ability to finish might depend on optimisation level I'm afraid.
2015-02-07T15:16:25 < DrLuke> arm-none-eabi-gdb
2015-02-07T15:16:36 < DrLuke> optimization is O0
2015-02-07T15:21:24 < PaulFertser> DrLuke: so you say that you "continue" and then the target runs but doesn't hit the breakpoint you set?

2015-02-07T15:21:50 < DrLuke> PaulFertser: Yes, but if I manually step, it does get to it within a few steps
2015-02-07T15:22:03 < PaulFertser> DrLuke: are you probably disabling gdb memory map in openocd config?
2015-02-07T15:22:14 < DrLuke> Not wittingly
2015-02-07T15:32:54 < PaulFertser> DrLuke: but when you single-step, the ISRs are sort of disabled.
2015-02-07T15:33:16 < DrLuke> PaulFertser: the ISRs still pop up when singlestepping
2015-02-07T15:33:47 < PaulFertser> DrLuke: what adapter are you using, stlink? Is "cortex_m maskisr" default ("auto")?
2015-02-07T15:34:18 < DrLuke> I'm using a stm32f0discovery board
2015-02-07T15:34:33 < DrLuke> I'm really new to ARMs so I have no idea what you just said :P
2015-02-07T15:34:44 < PaulFertser> DrLuke: how many breakpoints do you have? If no breakpoint is available, maskisr auto won't work.
2015-02-07T15:34:44 < Laurenceb_> <Tectu> Assfucked.Milfs.7.XXX.DVDRip.x264-Pr0nStarS
2015-02-07T15:34:48 < Laurenceb_> thanks Tectu
2015-02-07T15:34:59 < DrLuke> Just one breakpoint is set
2015-02-07T15:37:42 < PaulFertser> DrLuke: hm, stlink is special, maskisr isn't configurable for it anyway. I wonder what might be the issue there. Have you tried setting "hbreak" instead of "break"?
2015-02-07T15:39:07 < DrLuke> PaulFertser: Not yet
2015-02-07T15:41:17 < DrLuke> PaulFertser: It seems to work now
2015-02-07T15:41:23 < DrLuke> maybe I'm just too confused by GDB
2015-02-07T15:43:24 < PaulFertser> DrLuke: hm, if hbreak works but simple break doesn't and you're running from flash, it likely means gdb didn't get the memory map. What gdb version is that, what OpenOCD version and what config file are you using?
2015-02-07T15:44:13 < DrLuke> PaulFertser: It's pretty much the newest of all, since I'm running arch and I am using the arch repo version
2015-02-07T15:44:16 < PaulFertser> I recommend this as an intro to GDB http://www.slideshare.net/linaroorg/connect12-q2-gdb
2015-02-07T15:44:21 < DrLuke> I'm using the configs that came with openocd

2015-02-07T18:36:46 < Laurenceb_> they seem to be mapped in interrupts, but which ones?
2015-02-07T18:36:58 < englishman> Trollenceb, rpi USB works but is limited to stupid low mA with poly fuse
2015-02-07T18:37:04 < englishman> So shit appears to not work.
2015-02-07T18:37:11 < englishman> I jumperrd with solder bridge
2015-02-07T18:37:17 < Laurenceb_> i thought it had broken drivers too?
2015-02-07T18:37:31 < englishman> Well, that's due to lunix

2015-02-07T18:44:33 < zyp> they can apparently only be either off or interrupt output

2015-02-07T20:04:41 < karlp> more than others I guess.

2015-02-07T20:57:06 < bvernoux> with MCU @168MHz for example
2015-02-07T20:57:26 < bvernoux> I have not done a benchmark ;)
2015-02-07T20:57:31 < bvernoux> and it was on LPC43xx ;)

2015-02-07T20:58:02 < bvernoux> synchronized on ext clock or int
2015-02-07T20:58:18 < bvernoux> with a dedicated port of course so max 16bits

2015-02-07T21:02:53 < kakeman> interesting
2015-02-07T21:03:18 < bvernoux> just for info a loop with str on M4 work at 84MHz with MCU @168MHz ;)

Is that probably because arm-none-eabi-gcc is just not enough for the lib, like it expects to be compiled for "normal" ;) systems?

2015-02-07T21:23:48 < Getty> but now it really compiles after that, and this autoreconf is actually doing that now for arm-non-eabi?
2015-02-07T21:23:52 < Getty> cause of the configure before?
2015-02-07T21:24:44 < Getty> AH DAMN!...... the struct tm in newlib is not like the struct tm in libc as it seems.....
2015-02-07T21:24:46 < PaulFertser> Getty: autoreconf just updates everything to your current versions, not arm-none-eabi specific
2015-02-07T21:24:58 < PaulFertser> newlib is pretty POSIX-friendly I'd say
2015-02-07T21:25:13 < Getty> yeah but no tm->tm_gmtoff
2015-02-07T21:25:30 < Getty> which is ssomething he expect from struct tm, which apparently isnt there on newlib
2015-02-07T21:27:05 < PaulFertser> Getty: "man 3 strptime" doesn't list it

2015-02-07T21:27:41 < PaulFertser> Getty: so, what was the libtool issue? Did autoreconf solve it?
2015-02-07T21:27:44 < Getty> PaulFertser: thats awkward, in his code he clearly "Just" uses struct tm, he doesnt define it, and he references that it comes from sys/time.h

2015-02-07T21:28:04 < PaulFertser> Getty: sys/time.h vs time.h
2015-02-07T21:28:14 < Getty> uh! so sys/time.h is "special"?
2015-02-07T21:29:00 < PaulFertser> Getty: # ifdef __USE_BSD
2015-02-07T21:29:12 < PaulFertser> Getty: that field is bsd-specific but glibc supports it.
2015-02-07T21:29:44 < Getty> you confuse me now, where is that?
2015-02-07T21:29:58 < PaulFertser> Getty: I just opened /usr/include/time.h on my host.
2015-02-07T21:30:48 < Getty> there are 2 things in the config.h that might be relevant: "Define to 1 if you can safely include both <sys/time.h> and <time.h>." "Define to 1 if your <sys/time.h> declares `struct tm'." the first one is set, the second one isnt
2015-02-07T21:30:59 < PaulFertser> Getty: doesn't matter
2015-02-07T21:31:08 < Getty> could it be that the configure is not doing it right and i might have to enforce something?
2015-02-07T21:31:09 < Getty> ok.....
2015-02-07T21:31:14 < PaulFertser> Getty: just wth he's using BSD extensions?
2015-02-07T21:31:42 < Getty> the lib is libnova, its a lib for astronomical stuff, i can imagine that not all his decisions in planning the lib were wise
2015-02-07T21:32:42 < PaulFertser> Getty: there's just no support for that non-standard field in POSIX, and no support in newlib.
2015-02-07T21:32:58 < Getty> damn......
2015-02-07T21:33:08 < PaulFertser> Getty: come on, you have the sources.
2015-02-07T21:33:14 < PaulFertser> Just do whatever needed yourself.
2015-02-07T21:33:18 < PaulFertser> And contribute back :)
2015-02-07T21:33:45 < Getty> hehehe, the question is now if that is the best way, could be a snake of things todo
2015-02-07T21:34:26 < PaulFertser> Getty: you can try to stub it out for starters to see if there're many more issues

2015-02-07T21:39:01 < Getty> usleep <rolleyes>
2015-02-07T21:39:32 < Getty> ah in the tests he uses usleep............. <gnarg>
2015-02-07T21:39:59 < PaulFertser> Getty: but newlib has usleep?
2015-02-07T21:40:07 < Getty> i dont have usleep?
2015-02-07T21:40:20 < Getty> i should have usleep?
2015-02-07T21:40:51 < Getty> talking about C, throwing a lot of ? at each other
2015-02-07T21:40:57 < PaulFertser> :)))
2015-02-07T21:41:22 < Getty> but hey, funny, WIN32 has no usleep
2015-02-07T21:41:31 < Getty> so he has a usleep implemented extra for WIN32
2015-02-07T21:42:01 < Getty> aaaahhh mmmhhh <scratchhead> you are right i have usleep, adding it just let it crash
2015-02-07T21:43:16 < PaulFertser> Getty: I see -lgloss in newlib got usleep but then you need to provide _clock() for it.
2015-02-07T21:43:41 < Getty> yea its awkward, i get this error: test.c:(.text+0x6a8): undefined reference to `usleep' but making my own usleep means i override the definition
2015-02-07T21:43:52 < Getty> totally awkward, so i just add -lgloss to the configure LIBS?
2015-02-07T21:44:13 < Getty> or i just remove the test from the makefile ;) fi...
2015-02-07T21:44:39 < Getty> OK!.... so thats compiled....
2015-02-07T21:45:20 < PaulFertser> Was so easy, thanks to autotools!
2015-02-07T21:45:33 < PaulFertser> ;)
2015-02-07T21:45:54 < Getty> yeah thanks for the hints, i seriously have no idea what i am doing on those details (yet)
2015-02-07T21:46:35 < Getty> especially in those cases where you are using "bare ARM" and the library is not aware that those exist ;)
2015-02-07T21:46:53 < Getty> the gmtoff thing is actually something that is easy to fix
2015-02-07T21:46:59 -!- Vutral [~ss@mirbsd/special/Vutral] has joined ##stm32
2015-02-07T21:47:14 < PaulFertser> Getty: newlib has to count on you to provide some core functions that depend on your target platform. libnosys has the simplest stubs, suitable for microcontrollers. And you mention -lc before it so that libc could use the symbols from libnosys.
2015-02-07T21:48:19 < Getty> yeah but in the lib case its a bit confusing that all this is "directly" relevant, i mean.... i cant provide a clock function somewhere for a lib, so i think its just a bad case that this lib has tests
2015-02-07T21:48:23 < Getty> those tests just assume you have a real OS
2015-02-07T21:49:16 < PaulFertser> Getty: doesn't it have an option to disable tests?
2015-02-07T21:49:45 < PaulFertser> You do not need that executable anyway, not that you're going to run it on target.
2015-02-07T21:49:51 < Getty> well configure is not showing one
2015-02-07T21:51:10 < PaulFertser> Getty: btw, you do not seem to specify appropriate CFLAGS to have it built with hardware FPU support, why?
2015-02-07T21:51:29 < Getty> but in the end now, i technical would have to make something configure-test-script that actually checks if this struct tm has a gmtoff, and if not sets a define that can be used in code to change behaviour?
2015-02-07T21:51:55 < Getty> PaulFertser: dude..... doing it better is the step after making it work ;)
2015-02-07T21:52:09 < PaulFertser> Getty: I'd rather just ripped gmtoff handling off altogether in favour of in-lib code.
2015-02-07T21:52:25 < Getty> in the code there is a remark that says that there is no other way to get that information else
2015-02-07T21:52:47 < Getty> i mean yeah there is i can provide it but the lib is just not made for that i believe, i think a switch that just sets the internal gmtoff to 0 is enough
2015-02-07T21:52:56 < PaulFertser> Getty: btw, OpenOCD has experimental FPU support now, see http://openocd.zylin.com/#/c/514/19
2015-02-07T21:52:59 < Getty> (thats what i actually did now)
2015-02-07T21:53:22 < Getty> i am really not that far :) but i will come to those details
2015-02-07T21:53:59 < Getty> i already had no time to clear that topic up about network checksum, which should be managed by hardware but when i activate that it makes wrong checksums, i can fix all that later
2015-02-07T21:54:04 < Getty> i dont actually have a "power" problem

2015-02-07T21:55:18 < PaulFertser> Getty: I do not think gmtoff is that important. If you were using some function to get struct_tm, you already know what timezone was set.
2015-02-07T21:55:50 < Getty> PaulFertser: exactly my thought,t he problem is just administrative here now
2015-02-07T21:56:03 < Getty> PaulFertser: how to best offer a patch to libnova
2015-02-07T21:56:20 < Getty> i think an auto detect would be really good
2015-02-07T21:56:36 < Getty> but i will do that later, lets first see if it REALLY works now ;) calling some functions and stuff
2015-02-07T21:57:03 < PaulFertser> What's bad about localtime is that it counts on env variable to get the current timezone, and I do not think that's thread-safe.
2015-02-07T21:57:15 < PaulFertser> Timezone conversion sucks in POSIX.
2015-02-07T21:57:49 < Getty> the fun part is that i have all those infos, but injecting this into the lib is  more complex as just converting the time before dispatching to the lib ;)

2015-02-07T22:07:02 < PaulFertser> Getty: yes, la is just a libtool file. You need to make install. Or just grab the lib from ".libs/"

2015-02-07T22:18:04 < zyp> because I didn't bother resetting the paypal password that I forgot
2015-02-07T22:19:03 < Tectu> okay
2015-02-07T22:20:16 < Tectu> should I order you one?
2015-02-07T22:27:55 < PaulFertser> jpa-: Note how libtool creates extra files in the .libs subdirectory, rather than the current directory. This feature is to make it easier to clean up the build directory, and to help ensure that other programs fail horribly if you accidentally forget to use libtool when you should.
2015-02-07T22:30:22 < ds2> that is part of what makes it evil

2015-02-08T02:16:37 < Getty> today i learned..... if your image gets too big, you should read the .map about WHY.......
2015-02-08T02:17:30 < specing> today I learned Im as clueless as ever.
2015-02-08T02:17:43 < Getty> PaulFertser: just some basic functionality like... getting sunrise and sundawn sucks in 150k of ROM 8-) with this libnova
2015-02-08T02:18:02 < Getty> but most of that is actually the libc/newlib functions it uses
2015-02-08T02:18:50 < qyx_> why are you always trying to use libraries not intended for embedded?
2015-02-08T02:19:30 < Getty> which other you mean? tinycdb worked fine :) and still: if there is code that does what i want, i should try it to run it on there, or?
2015-02-08T02:19:46 < Getty> i mean i would be pretty retarded to not see if it works out that way and instead directly start to learn astronomy....

2015-02-08T02:27:52 < qyx_> internet is full of readymade equations and code samples to calculate sunrise time
2015-02-08T02:28:04 < qyx_> instead of wasting 150K of flash space
2015-02-08T02:28:24 < Getty> qyx_: yeah, if i would ONLY want that FOREVER i would do that
2015-02-08T02:28:32 < Getty> qyx_: but it seems you know my requirements better as I do
2015-02-08T02:28:40 < qyx_> you said that
2015-02-08T02:28:59 < Getty> i said it as part of the requirements, the more astronomy stuff i have the more features i can offer
2015-02-08T02:29:16 < Getty> so integrating a more complex lib and just use a limited function set of it, makes sense
2015-02-08T02:29:24 < Getty> didnt expected it to blow up so big, but i tried, whats the problem?
2015-02-08T02:29:34 < qyx_> ok, whatever
2015-02-08T02:30:50 < Getty> also its better for the bigger thought, if i would have used that lib and supplied patches and stuff more people would have been able to enjoy
2015-02-08T02:31:06 < Getty> so its always wise, for the great good of us all, to checkup the organized libraries instead of "grapping snippets"
2015-02-08T02:32:32 < GargantuaSauce_> https://www-robotics.jpl.nasa.gov/publications/Khaled_Ali/ieee05_smc_hga.pdf came across this last night, kinda related
2015-02-08T02:34:36 < Getty> yeah libnova can calculate all this hehe :)
2015-02-08T02:34:51 < Getty> i bet at least ;)
2015-02-08T02:35:20 < GargantuaSauce_> does it make your morning coffee too?
2015-02-08T02:39:31 < Getty> it should!
2015-02-08T02:39:43 < Getty> yeah well it lets you calculate probably where to put your coffee to get it hot by the sun directly
2015-02-08T02:39:51 < karlp> Getty: why are you not just using an embedded linux module anyway? instead of trying to fit all your high level stuff into a micro just because you want to control some leds as well?
2015-02-08T02:40:15 < Getty> karlp: cause that would significant change the production cost?
2015-02-08T02:40:27 < Getty> karlp: you do realize that i dont do a single version here, or?
2015-02-08T02:40:56 < karlp> I don't think you realise how cheap linux modules are...
2015-02-08T02:41:28 < Getty> karlp: yeah well now this arm is in, and its far by enough, and i dont see a reason to explode, cause the lib i tried just is too big
2015-02-08T02:41:50 < Getty> i have seriously no idea why it is a reason to attack if i try things, does this have any sense?
2015-02-08T02:42:06 < karlp> it's enough? every other day you're here with, "oh shit, this lib blew up my flash" or "oh shit, this tiny ip networkign stack doesn't do the networking I thought it would" or "oh shit, this other lib expects posix"
2015-02-08T02:42:16 < Getty> yeah?
2015-02-08T02:42:18 < Getty> cause i try a lot?
2015-02-08T02:42:24 < Getty> and i have everything i want
2015-02-08T02:42:41 < Getty> the thing delivers a high quality modern rich web application, i have general communication layer via msgpack between javascript and the system, its all working out fine
2015-02-08T02:43:04 < Getty> speed is super, firmware upgrade via click in the webinterface with fancy download/upload animation
2015-02-08T02:43:21 < Getty> i am happy, i just try a lot and fail while doing so, thats how you get to bigger results, if you try big and fail
2015-02-08T02:43:38 < Getty> if i would everytime work like my dad noone would care about the end product, if its just "what electronican would make"

2015-02-08T02:44:49 < Getty> and with my experience over 20 years in the software development area in the internet, i think i can value some things pretty good, sadly i cant value "expected functions used in libs, expected flashsize used by lib".... ;) especially so fresh into that
2015-02-08T02:46:30 < Getty> we btw made before a similar product which was a board with more features even combined with a raspberry pi, but the customers didnt wanted that, the price was too high, this product now is planned with the customer (a reseller) who knows what the people pay for what, and we just pack it into the cost
2015-02-08T02:47:08 < Getty> my dad sadly isnt aware of "all options" on the chips, and so we picked something "accessable" for us (one processor that actually is on an evaluation board with network) so that we were able to "copy" and still make the product early
2015-02-08T02:47:14 < Getty> i just try to bring it to the max ;)
2015-02-08T02:47:24 < Getty> and its a HUGE fun :D

2015-02-08T05:47:13 < dongs> a range of 2.5v to 3.9v will not cause problems with most digital systems designed to run at 3.3v so a ldo from a lipo in most cases will work. Efficiency of a ldo is equal to vout/vin so in this particular case will be almost 90% which is where most switch modes run.

2015-02-08T08:41:00 < Getty> PaulFertser: yeah its really WAY too much, which is mainly in the fact that it includes giant const blobs of astronomical data
2015-02-08T08:41:29 < Getty> PaulFertser: i remove a lot of them but i cant remove the "Lunar" one, else i lose the feature for detecting the moonphase, and then this all gets ridicioulus pointless
2015-02-08T08:42:10 < PaulFertser> Getty: unused data should be garbage-collected. Probably when the lib is built it's lacking -ffunction-sections or -fdata-sections.
2015-02-08T08:42:19 < Getty> even _IF_ i remove lunar i am still 40k over my limit ;)
2015-02-08T08:42:47 < Getty> when i check the main.map i see that most of it is actually coming from newlib, as A LOT of math functions are sucked in
2015-02-08T08:44:01 < PaulFertser> Is that with hard FPU? newlib is usually compiled in multilib fashion, so you might get small fpu-enabled code if you use one set of switches and large emulated code if you use another.
2015-02-08T08:45:19 < PaulFertser> And all of the functions and data you do not use should get garbage-collected during the final linking phase.
2015-02-08T08:46:20 < PaulFertser> (of the elf you're about to flash, not the library)
2015-02-08T08:46:50 < PaulFertser> Also, if printf and friends are taking much space, you can probably use newlib-nano instead.
2015-02-08T08:47:09 < PaulFertser> (gcc arm embedded comes with both newlib and newlib-nano and a handy spec file to choose)

2015-02-08T09:47:15 < zyp> Through the course of WLCSP development, Fairchild has demonstrated that BSL is neither a necessity for backside silicon chipping, nor a significant factor for board-level reliability. Light-sensitive circuit protection, as claimed in literatures, is not a reality concern since silicon is only transparent to long wavelength light, which is rarely encountered in broad applications of WLCSP.

2015-02-08T10:19:06 < upgrdman> this dingleberrypi flash problem, does it only occur if the flash is upclose, or will like normal distances cause problems too?
2015-02-08T10:19:28 < upgrdman> some dildo made a youtube video of the problem, but he had his point-and-shit camera maybe 2" from the pcb
2015-02-08T10:20:23 < PeterM> The DSBGA package is optimized for the smallest possible size in applications with red or infrared opaque
2015-02-08T10:20:24 < PeterM> cases. Because the DSBGA package lacks the plastic encapsulation characteristic of larger devices, it is
2015-02-08T10:20:24 < PeterM> vulnerable to light. Backside metallization and/or epoxy coating, along with front side shading by the printed
2015-02-08T10:20:24 < PeterM> circuit board, reduce this sensitivity. However, the package has exposed die edges. In particular, DSBGA
2015-02-08T10:20:24 < PeterM> devices are sensitive to light, in the red and infrared range, shining on the package’s exposed die edges.

2015-02-08T11:16:24 < dongs> still need to write code for that one, too
2015-02-08T11:17:34 < zyp> how much is that panel btw?
2015-02-08T11:17:47 < dongs> no clue it was sent to me
2015-02-08T11:17:57 < dongs> lemme find part#

2015-02-08T11:22:38 < zyp> hmm, looks pretty decent
2015-02-08T11:23:18 < dongs> thinking to do http://www.digikey.com/product-detail/en/ISL97687IRTZ/ISL97687IRTZ-ND/2773206 for led driver
2015-02-08T11:23:22 < dongs> not found anything better

2015-02-08T11:34:52 < PeterM> he phaseshift functionality is nice
2015-02-08T11:38:11 < dongs> zyp, other than availabilityy
2015-02-08T11:38:23 < PeterM> means even if you have garbage pwm you wont getstrobing as bad
2015-02-08T11:40:14 < dongs> ADD5211 is another one
2015-02-08T11:40:30 < dongs> but specs are kinda mum about max fb voltage
2015-02-08T11:40:36 < dongs> i see 45 in acouple places, it might be that
2015-02-08T11:43:42 < PeterM> nah - they show strings of 22 leds in app notes
2015-02-08T11:44:09 < dongs> thats ~50?
2015-02-08T11:44:42 < PeterM> closer to 60
2015-02-08T11:44:49 < dongs> oh hm
2015-02-08T11:44:55 < dongs> the panel is 17 leds
2015-02-08T11:45:32 < dongs> 3.05V/led?
2015-02-08T11:45:58 < dongs> hmm, that one's also on digikey
2015-02-08T11:47:22 < dongs> about same number of external parts as ISL
2015-02-08T11:49:05 < dongs> i wonder why these panels dont break out vsync
2015-02-08T11:49:12 < dongs> to the connector
2015-02-08T11:49:21 < dongs> so you could do that pro gaymer strobing stuff
2015-02-08T11:50:08 < PeterM> can youir double penetration chip extact the vsync?
2015-02-08T11:50:16 < dongs> pfft, of coruse not
2015-02-08T11:51:40 < PeterM> anyway, i'd say you're safe to ue that AD chip with your 17LED string
2015-02-08T11:54:25 < dongs> cant decide if isl is more or less pro
2015-02-08T11:55:38 < upgrdman> is it more efficient for lcd makers to just wire all the led's in series? i mean, is doing the high-ish voltage setup cheaper than a few channels or low-ish voltage led strings?
2015-02-08T11:55:54 < upgrdman> *few channels of...
2015-02-08T11:56:03 < PeterM> its cheaper to bring 2 wires out instead of 20
2015-02-08T11:56:32 < PeterM> panel mfg dgaf about led drivers
2015-02-08T11:56:46 < PeterM> well, panel packagers
2015-02-08T11:56:53 < upgrdman> sure, but the big customers care about total BOM cost, no?
2015-02-08T11:58:32 < zyp> my guess is that a boost converter is cheaper than a ton of sink drivers
2015-02-08T11:58:57 < zyp> and probably have better efficiency too, since the boost voltage can be scaled to an appropriate value
2015-02-08T11:59:20 < upgrdman> k
2015-02-08T11:59:25 < zyp> the sink drivers do linear regulation, after all
2015-02-08T11:59:41 < upgrdman> ya
2015-02-08T12:00:04 < zyp> actually, that's probably the main reason

2015-02-08T13:37:22 < dongs> its fucking retarded largte
2015-02-08T13:37:23 < PeterM> 80mm^2 is pretty big

2015-02-08T13:42:11 < zyp> dongs, so how big was that dual channel reg layout you talked about the other day?
2015-02-08T13:42:25 < zyp> I think you talked about how small it was

2015-02-08T13:42:34 < dongs> this?

2015-02-08T13:42:51 < dongs> its not too awful
2015-02-08T13:43:02 < dongs> this is 0402 + 0604
2015-02-08T13:43:35 < zyp> I think you said 1cm2, which is 100mm2
2015-02-08T13:43:46 < zyp> well, 94mm2 judging by pic
2015-02-08T13:43:57 < PeterM> which is 2 regulators
2015-02-08T13:44:16 < zyp> it's one dual regulator
2015-02-08T13:44:21 < zyp> but yeah
2015-02-08T13:44:21 < qyx_> wait what
2015-02-08T13:44:30 < qyx_> 80mm^2 isnt that large actually
2015-02-08T13:44:38 < zyp> that's my point
2015-02-08T13:44:43 < qyx_> i though it is like 2x4cm
2015-02-08T13:44:46 < qyx_> math error

2015-02-08T14:33:01 < dongs> he had something to show ( = zano style ) then when he got the money he started working on "new prototypes" that never worked right
2015-02-08T14:33:24 < dongs> apparently what he was trying to do waws not possible after all cuz dick24 SPI will insert a short pause on each byte while DMAing it
2015-02-08T14:33:32 < dongs> instead of just streaming nonstop
2015-02-08T14:33:39 < PeterM> i wonder why they didnt work, i cant put my finger on it

2015-02-08T14:36:55 < BrainDamage> did he apply molten solder from a squirt bottle?
2015-02-08T14:37:22 < PeterM> from the colour of the board it was more liek has backside
2015-02-08T14:38:23 < PeterM> if i soldered that badly i wouldnt show anyone

2015-02-08T14:43:11 < dongs> Harris thought the Hitachi sounded very ethereal, almost out of phase, and rated it lowest; the Seagate was sharper with a more thumpy bass, slightly brighter with a slight tendency to sibilance. Both lacked much drive in presenting the Madonna track, and were certainly .mushy. [.]

2015-02-08T17:30:45 < dongs> how the fuck are tehy doing 22 leds then

2015-02-08T17:36:52 < dongs> so thats more like 3.05V
2015-02-08T17:37:22 < zyp> but does the FB pins see the full voltage, or just a divided one?

2015-02-08T17:38:51 < dongs> ya
2015-02-08T17:39:28 < zyp> doesn't need to handle more than vled - forward voltage
2015-02-08T17:39:46 < dongs> forward voltage sum of all leds?
2015-02-08T17:39:47 < zyp> unless the string fails short and makes the forward voltage 0
2015-02-08T17:39:55 < zyp> obviously
2015-02-08T17:40:06 < zyp> since that's the difference between vled and fb

2015-02-08T17:44:04 < dongs> zyp, i see now, there's a short protection thing per fb pin, and they're talking about FB voltage raising above like 5V and shit
2015-02-08T17:44:20 < dongs> (to trigger short protection)
2015-02-08T17:44:28 < zyp> wonder if sunlight would be harmful for the stm32f4 in WLCSP90

2015-02-08T23:54:01 < zyp> not like it matters since people apparently won't use two urinals next to each other anyway
2015-02-08T23:54:23 < zyp> ref. all the urinal etiquette bullshit
2015-02-08T23:54:44 < kakeman> zyp: the point is to pee inboth
2015-02-08T23:54:57 < kakeman> without spilling to floor
2015-02-08T23:55:12 < kakeman> rotate 90 pee rotate 90 pee

2015-02-08T23:55:21 < kakeman> rotate and pee
2015-02-08T23:57:08 < kakeman> well it's not the point but obivious action there
2015-02-08T23:57:20 < zyp> on that topic, I don't really get why some people have issues with using an urinal next to an occupied one
2015-02-08T23:57:28 < zyp> anybody around who can elaborate?
2015-02-08T23:57:40 < kakeman> penis issues
2015-02-08T23:57:53 < zyp> like what?
2015-02-08T23:57:57 < Fleck> where are you from zyp?
2015-02-08T23:58:06 < zyp> Fleck, how does that matter?
2015-02-08T23:58:12 < kakeman> in mind of course not in penis
2015-02-08T23:58:22 < Fleck> culture matters
2015-02-08T23:58:22 < upgrdman> my issue is that the urinals are placed too close together. i dont want to touch shoulders with some guy when i pee
2015-02-08T23:58:41 < zyp> why not?
2015-02-08T23:59:25 < zyp> I also haven't seen urinals placed that close together
2015-02-08T23:59:35 < kakeman> I have friends that go in this gayphobic state when they see someone peeing
--- Day changed Mon Feb 09 2015
2015-02-09T00:00:04 < kakeman> and keep repeating "gay gay gay"
2015-02-09T00:00:45 < kakeman> and some I have peed cross with
2015-02-09T00:00:50 < zyp> Fleck, I'm norwegian

2015-02-09T00:03:34 < kakeman> not too long obiviously
2015-02-09T00:03:34 < PeterM> some times im just not down for standing close enoug hto someone else for their piss to splatter onto me
2015-02-09T00:03:46 < Laurenceb_> loool
2015-02-09T00:03:48 < kakeman> maybe around flats and back inside?
2015-02-09T00:04:44 < zyp> I don't find splatter to be a common problem
2015-02-09T00:04:45 < kakeman> or street run naked and back inside apartment
2015-02-09T00:04:58 < zyp> except that time I were transferring planes in france a couple of years ago
2015-02-09T00:05:10 < zyp> their urinals appeared to be designed like retroreflectors
2015-02-09T00:06:31 < zyp> kakeman, speaking of walking naked, isn't that what you finns do around your saunas?
2015-02-09T00:08:45 < zyp> I haven't walked around naked outside since… uh, last week
2015-02-09T00:11:09 < Fleck> ;p
2015-02-09T00:11:47 < zyp> but that was in japan, not norway, so it doesn't count
2015-02-09T00:12:36 < Getty> yeah japan never counts
2015-02-09T00:13:27 < Getty> but its really awesome to get into the freezing cold after sauna.................. now i wanna do it

2015-02-09T00:19:40 < upgrdman> at my uni the urinials are like 2' (60cm) apart, on center. super fucking annoying

2015-02-09T01:22:19 < kakeman> I could had some fly hours for fun but not far enough for anything usable
2015-02-09T01:23:27 < kakeman> the deal was I could learn myself fly just having a guy next to me taking over if something happend
2015-02-09T01:24:10 < englishman> yes tehre are usually minimum hours of dual instruction
2015-02-09T01:24:20 < kakeman> that sounds good to my impatient ears
2015-02-09T01:24:23 < englishman> then you can solo after ~10 hours, dont know about helis tho
2015-02-09T01:24:33 < englishman> then you get your tie cut off or water dunked on you, etc
2015-02-09T01:25:02 < englishman> but if you want to train for ppl, you need to treat it as a full time course, fly every 2 days at minimum
2015-02-09T01:25:08 < englishman> otherwise you just waste time and money
2015-02-09T01:25:24 < englishman> and study every day
2015-02-09T01:25:35 < englishman> simulator at home helps too
2015-02-09T01:25:45 < englishman> then once you have the license, you can relax a bit
2015-02-09T01:25:53 < englishman> but you still have to maintain and fly every month at minimum
2015-02-09T01:26:03 < englishman> and dual instruction refresher every year

2015-02-09T01:28:16 < kakeman> I held my mount there and I was wet of sweat
2015-02-09T01:28:55 < kakeman> they had to repeat moves for multiple times because pilot failed every time
2015-02-09T01:29:19 < kakeman> some tilting and rolling same time from side to side

2015-02-09T01:37:50 < zyp> hmm, there's also the coming LAPL
2015-02-09T01:38:33 < zyp> which iirc allows for a MTOW of up to 2000kg, compared to the 475kg or so for the current ultralight rules
2015-02-09T01:42:24 < kakeman> expermantal is way to go
2015-02-09T01:42:30 < kakeman> at least in here
2015-02-09T01:43:08 < zyp> how so?
2015-02-09T01:45:06 < kakeman> byro and money things
2015-02-09T01:45:21 < kakeman> are eased
2015-02-09T01:47:11 < zyp> well, I mean, experimental might be the way to go to own an aircraft
2015-02-09T01:47:18 < kakeman> yes
2015-02-09T01:47:42 < zyp> but doesn't really have anything to do with kind of license and related costs
2015-02-09T01:48:46 < kakeman> still needs licence
2015-02-09T01:50:34 < kakeman> just read that maintenance of a plane doesn't require licenced person
2015-02-09T01:50:54 < zyp> norwegian ultralight rules also allow for that
2015-02-09T01:51:08 < kakeman> that equals big pile of money
2015-02-09T01:55:01 < zyp> my line of thought is that an ultralight license allows me to go flying some day I'm bored, which is primarily what a private license also would be useful for
2015-02-09T01:57:03 < qyx_> mhm, when i try to enable a peripheral clock (rcc), my freertos hangs
2015-02-09T01:57:23 < qyx_> and i am lazy to run a debugger
2015-02-09T01:57:35 < kakeman> yes ultra is way to go definitelly
2015-02-09T01:58:07 < zyp> having a private license for travel doesn't really make sense since you won't beat airlines on price
2015-02-09T01:58:34 < kakeman> i thought i would get sail plane licence and then engine powered sail plane licence
2015-02-09T01:59:31 < kakeman> and from there is short way to ultra
2015-02-09T02:00:26 < zyp> also, if I later decide I want a private license, I'll save money on private training since the actual flying skills should transfer rather well requiring less training (and you can count some of the ultra hours towards the minimums for private)
2015-02-09T02:02:08 < zyp> of course, going ultra -> private will be more expensive than going direct to private if private is the goal, but the per-hour cost will be lower

2015-02-09T08:40:20 < dymk> yeah I'm confused, now
2015-02-09T08:40:43 < dymk> Debugger says that the stm32f4_discovery.c's ports are basically garbage values
2015-02-09T08:40:45 < dymk> They're in an array
2015-02-09T08:40:57 < dymk> An array of what should be four GPIODs
2015-02-09T08:41:18 < dymk> Adding an assert_param(GPIO_PORT[Led] == GPIOD) fails, of course
2015-02-09T08:42:51 < dymk> not sure if anyone here is familiar with the stm32f4_discovery.c file that ST provides in cubef4
2015-02-09T08:43:55 < emeb_mac> not used cube. stdperiph only.
2015-02-09T08:45:18 < dymk> would you suggest stdperiph over cube?
2015-02-09T08:45:31 < dymk> because at this point i'd rather go with the better supported of the two
2015-02-09T08:45:54 < emeb_mac> I like stdperiph, but just because it's what I'm used to.
2015-02-09T08:47:14 < akaWolf> dymk: there is always "depends on..." ;)
2015-02-09T08:47:22 < dymk> haha that is true
2015-02-09T08:47:35 < dymk> Well I've got no prior experience, so it doesn't really matter much to me
2015-02-09T08:48:10 < dymk> although I am having a hard time finding documentation on stdperiph on st's website; is it just superseded by cube?
2015-02-09T08:48:50 < jpa-> nah, it was always poorly documented
2015-02-09T08:48:55 < jpa-> there is a pdf manual or something
2015-02-09T08:49:05 < jpa-> if you want something that has documentation, use the registers directly

2015-02-09T09:55:30 < upgrdman> ok, that kinda makes sense
2015-02-09T09:56:11 < upgrdman> what kinda power? your 4k panel needed what, 50V @ what mA?
2015-02-09T09:56:23 < dongs> 120mA per string, 4 strings
2015-02-09T09:56:27 < dongs> so ~500mA

2015-02-09T09:57:31 < upgrdman> must be shitting Rds-on if the fets dissipate much. 25W isn't all that much

2015-02-09T09:59:07 < elektrinis> anyone familiar with sleep modes here?
2015-02-09T09:59:24 < elektrinis> my devops are saying that you can not go to stop mode without resetting all peripherals
2015-02-09T09:59:42 < elektrinis> and switching digital IOs off
2015-02-09T09:59:55 < elektrinis> can that be true?
2015-02-09T10:00:13 < dongs> 346.56	mW  (this is the typical minimum power dissipation inside the ADD5211 from the current sinks).
2015-02-09T10:00:21 < dongs> ^ this is for 120mA/string * 4
2015-02-09T10:00:32 < dongs> i dont think it will need heatsink

2015-02-09T10:43:49 < jpa-> the higher the voltage, the thinner wires you can use
2015-02-09T10:44:05 < jpa-> but once you go over 20 volts, you need more sturdy FETs etc.
2015-02-09T10:50:39 < PeterM> jpa- ofc but it's not goign to make that much difference
2015-02-09T10:51:08 < PeterM> instead fo hour charge, now takes hour 10 mins
2015-02-09T10:52:35 < jpa-> 1:20 it seems to me
2015-02-09T10:52:45 < jpa-> but, "why not"
2015-02-09T10:53:06 < jpa-> once you are at 13V instead of 12V, you already need a quite custom power supply, so why not make it 19V
2015-02-09T10:53:30 < PeterM> jpa- once you enter the cv part of charing the extra current offfers you nothing
2015-02-09T10:55:36 < PeterM> also 12>13v if preobably within transformer winings margin of error so just a resistor value tweak, 12->19 isnt tho
2015-02-09T10:55:41 < jpa-> isn't the battery like 90% full at CV start?
2015-02-09T10:56:08 < PeterM> yes, but cv takes mre than 10% of time ebcause the current tapers significantly
2015-02-09T10:56:44 < jpa-> nitpicking anyway, the power supply has to supply the PC in addition to charging
2015-02-09T10:56:59 < jpa-> so instead of increasing charge time, you just would need thicker wires
2015-02-09T10:57:42 < jpa-> being "inside margin of error" does not help if that means that half of your units will be in the other end of the "margin of error"
2015-02-09T10:59:16 < PeterM> margin of error  is not correct eterm - i should have said tolerance for output voltage

2015-02-09T11:02:01 < jpa-> besides, IIRC the 19V chargers were already common in the NiMH era
2015-02-09T11:02:22 < PeterM> but nto of the required current
2015-02-09T11:03:06 < jpa-> ?
2015-02-09T11:03:37 < jpa-> you say that 90's laptops used less power than modern ones?
2015-02-09T11:03:53 < PeterM> no, i say their battery life was garbage
2015-02-09T11:05:03 < jpa-> the operating current of the laptop determines the power requirements for charger - charging the battery fast is just a bonus
2015-02-09T11:05:37 < jpa-> all li-ion SMPS chips that i have seen will gracefully reduce the charging current when the input voltage starts to drop
2015-02-09T11:05:40 < PeterM> the operating current is insignificant compared to the charge current of the battery
2015-02-09T11:06:43 < jpa-> how so? modern laptops can draw the battery empty in less than an hour when you fully load it with a game - and usually you do not want to charge a li-ion battery at more than 1C if you want it to last
2015-02-09T11:07:08 < jpa-> sure, they draw a tiny amount of current when idle
2015-02-09T11:07:39 < PeterM> and what percentage of tiem do you think laptops are spent at idle?

2015-02-09T11:08:03 < jpa-> PeterM: what does that matter?
2015-02-09T11:08:16 < jpa-> of course the power supply has to be designed for maximum load, not for average load
2015-02-09T11:08:25 < PeterM> thats where you're wrong
2015-02-09T11:08:56 < jpa-> why?
2015-02-09T11:09:21 < PeterM> the mfg doesnt care if the battery still goes flat while th e device is plugged into AC if hardware is all maxed out
2015-02-09T11:09:49 < PeterM> because that is not going to occurr to a large percentage ofthe users
2015-02-09T11:10:16 < PeterM> they will just throttle hardware to allow laptop to continue running
2015-02-09T11:10:46 < jpa-> sounds like a crappy laptop if you cannot play a game when plugged in
2015-02-09T11:10:49 < PeterM> and if the laptop is deigned to run with hardware maxxed out, the mfg charges a permium for the privlidge
2015-02-09T11:11:17 < jpa-> i can't see any cost savings in going 13V anyway at this point
2015-02-09T11:11:31 < jpa-> 19V chargers are much more common than 12/13V 7A power supplies
2015-02-09T11:11:39 < GargantuaSauce> gaming laptop here, the thing can definitely charge (slower) when running at full tilt
2015-02-09T11:11:46 < GargantuaSauce> >200W supply
2015-02-09T11:12:05 < PeterM> GargantuaSauce, have you noticed thatr you payed significantly more for your laptop too?
2015-02-09T11:12:18 < jpa-> regular ultrabook here, it does charge when fully loaded, and it does drain out the battery in an hour when fully loaded
2015-02-09T11:12:29 < jpa-> significantly more than what?
2015-02-09T11:12:42 < GargantuaSauce> significantly more than a laptop without an i7 and high end gpu?
2015-02-09T11:13:02 < jpa-> you say that there is some evil conspiracy that forces *every* manufacturer to charge $100 for a $20 power supply?
2015-02-09T11:13:09 < PeterM> no
2015-02-09T11:13:56 < jpa-> in fact, i haven't ever owned a laptop that wouldn't charge when fully loaded - maybe because i don't buy the cheapest crap anyway
2015-02-09T11:14:15 < dongs> yeah uh, *none* of my laptops did that
2015-02-09T11:14:23 < dongs> that must be the worst of the worst clevo gayming notebooks
2015-02-09T11:14:26 < dongs> that dont charge while using
2015-02-09T11:14:28 < GargantuaSauce> let's talk about tablets refusing to charge off real usb hosts
2015-02-09T11:15:00 < PeterM> surface pro 3 can be loaded enoug\ that charger is insufficient
2015-02-09T11:15:10 < PeterM> dongs, try it
2015-02-09T11:15:21 < dongs> PeterM: i only use it for irc, havent had problems
2015-02-09T11:15:59 < PeterM> jpa-, thats why it matters^
2015-02-09T11:16:11 < jpa-> PeterM: isn't surface 3 with 12V charger anyway?
2015-02-09T11:16:21 < jpa-> maybe that's why it is so power-deficient :)
2015-02-09T11:16:21 < dongs> it might be 5V
2015-02-09T11:17:06 < PeterM> jpa- probably but tat was their design decision, design for AVERAGE  load, not maximum
2015-02-09T11:17:33 < jpa-> so you are angry that most manufacturers are sane, unlike microsoft?
2015-02-09T11:18:16 < PeterM> except most MFG do this on most laptops they sell (by volume)
2015-02-09T11:18:20 < jpa-> "why don't they use 12V? because it's not enough for max power? but look at surface 3, it uses 12V and fails at max power!"
2015-02-09T11:18:29 < jpa-> i have no source for that
2015-02-09T11:18:51 < PeterM> jpa- now you're twisting words for context

2015-02-09T11:19:00 < dongs> do you think if I have a canbus tranceiver powered by 5V and stm32 powered by 3.3, when I use factory plug to just flash STM, only powering 3V portion of the board, will it fuck up the can chip?
2015-02-09T11:19:21 < PeterM> or just being trolled which is totally plausable
2015-02-09T11:19:57 < jpa-> dongs: STM32 would typically keep its IOs in high-z, so shouldn't matter for the canbus tranceiver
2015-02-09T11:20:10 < dongs> jpa, but doesnt it try to do something with bootloader via CAN
2015-02-09T11:20:16 < jpa-> hmm
2015-02-09T11:20:33 < dongs> i guess i should read the appnote to see if it mentions what order it tries the boot devices
2015-02-09T11:20:38 < jpa-> maybe yeah
2015-02-09T11:21:05 < jpa-> series resistors should be enough protection in that case
2015-02-09T11:22:54 < dongs> that document is fucking dumb
2015-02-09T11:22:58 < dongs> no mentio nof order of things
2015-02-09T11:23:05 < dongs> but they talk about usart, usb, can ( in that order )
2015-02-09T11:23:06 < dongs> so maybe ok?
2015-02-09T11:23:58 < jpa-> i would assume it might try all at once
2015-02-09T11:24:03 < dongs> hah, nah

2015-02-09T11:25:36 < dongs> well, i might when userspace app is running
2015-02-09T11:25:40 < dongs> but for factory programming

2015-02-09T11:25:44 < dongs> yea only one can interface,
2015-02-09T11:26:19 < jpa-> so it configs CAN as push-pull immediately, then waits for frame.. i wonder what is the idle state of CAN tx pin
2015-02-09T11:26:24 < dongs> jpa-:o oh,
2015-02-09T11:26:26 < dongs> hmmm
2015-02-09T11:27:01 < dongs> so you tihnk 'GPIOs" fits under "configuring CAN gpio"?

2015-02-09T11:28:06 < dongs> hold on this shit doenst even have can bootloader
2015-02-09T11:28:09 < dongs> its F302

2015-02-09T14:12:57 < dongs> if im copypasting anything, i'd rather do it into excel
2015-02-09T14:14:09 < specing> octave is much, much more capable than excel, so no
2015-02-09T14:14:22 < specing> plus it is FOSS
2015-02-09T14:14:35 < dongs> most normal people consider that as a negative

2015-02-09T14:15:07 < dongs> like wtf
2015-02-09T14:15:08 < dongs> its 2015
2015-02-09T14:15:19 < Roklobsta> i used to use octave a lot as a poor man's matlab.  scilab is very good now.
2015-02-09T14:16:26 < karlp> specing: that was from when I'd gotten bored of copying and pasting
2015-02-09T14:16:53 < karlp> also, I was graphing a 1k sample buffer, and gdb's print format was too many screens to copy/paste easily
2015-02-09T14:17:57 < Roklobsta> karlp: how many bogans in iceland?
2015-02-09T14:18:24 < karlp> I didn't think I'd even posted my rednek racing numberplate yet...
2015-02-09T14:18:55 < karlp> bogans of a different sort than aus,
2015-02-09T14:19:10 < karlp> and a lot less honestly, or at least, a lot less visible than aus bogans
2015-02-09T14:19:13 < Roklobsta> lifting massive logs is very boganny.

2015-02-09T14:19:39 < karlp> strong man comps are great!
2015-02-09T14:19:50 < Roklobsta> well, i am sure the flanny is popular there.
2015-02-09T14:19:51 < specing> dongs: octave is an interpreter so getting a command line doesen't seem that far fetched, no?
2015-02-09T14:20:05 < karlp> Roklobsta: virtually unheard of
2015-02-09T14:20:17 < specing> dongs: plus your issue is using windows

2015-02-09T14:20:29 < dongs> specing: thats not my issue at all, windows works great
2015-02-09T14:20:32 < dongs> specing: i'm using Windows 8.1

2015-02-09T14:21:42 < Roklobsta> dongs: linux loads firefox just as well as win10.
2015-02-09T14:22:11 < specing> I dual booted  windows 98 & later XP
2015-02-09T14:22:18 < dongs> Roklobsta: but windows doesn't crash your entire desktop/login session when firefox takes a shit and kills Xserver
2015-02-09T14:22:20 < specing> always booted into Linux
2015-02-09T14:22:35 < specing> and finaly deleted the windows partition because I needed more space
2015-02-09T14:22:44 < dongs> cool story bro
2015-02-09T14:22:47 < dongs> 4TB drives are $150 now
2015-02-09T14:22:53 < karlp> not for ssd
2015-02-09T14:23:00 < specing> This was when HDDs were 25 GB
2015-02-09T14:23:02 < dongs> why the fuck would you need SSD for lunix
2015-02-09T14:23:09 < specing> I was around 10 back then
2015-02-09T14:23:11 < Roklobsta> dongs: aw, firefox hasn't done that to me in a while.  win7 explorer shititself/refresh cycle seems to happen now and then though.
2015-02-09T14:23:17 < specing> Linux has all the cool games
2015-02-09T14:23:22 < dongs> Roklobsta: again, taht doesnt kill all your running apps
2015-02-09T14:23:25 < specing> windows only had solitaire and pinball
2015-02-09T14:23:28 < Roklobsta> true

2015-02-09T14:24:37 < specing> https://en.wikipedia.org/wiki/Rocks%27n%27Diamonds this was the game I played when I was ~10
2015-02-09T14:24:49 < specing> and the reason I always booted into Linux
2015-02-09T14:25:50 < dongs> so its a retarded boulderdash ripoff?
2015-02-09T14:25:56 < Roklobsta> completely
2015-02-09T14:25:59 < Roklobsta> and 10 years late

2015-02-09T14:26:49 < dongs> well that too
2015-02-09T14:27:06 < specing> plus windows was horrible, always got malware and the settings were totaly inconsistent
2015-02-09T14:28:09 < Roklobsta> that's what you get for manually cleaning up the registry.
2015-02-09T14:28:32 < specing> I doubt I knew what the registry was when I was 10
2015-02-09T14:28:56 < Roklobsta> specing: were you axing about Ada the other day?
2015-02-09T14:29:10 < specing> 'axing'?
2015-02-09T14:29:17 < Roklobsta> asking
2015-02-09T14:29:21 < specing> yes
2015-02-09T14:29:26 < Roklobsta> did you get anywhere?
2015-02-09T14:29:33 < specing> I am slowly migrating to it
2015-02-09T14:29:52 < specing> exams now, so little time
2015-02-09T14:30:00 < specing> speaking of that

2015-02-09T14:32:12 < PeterM> specing - windows ges malware in tyhe same way guns kill people - idiots do things they shouldnt
2015-02-09T14:32:22 < Roklobsta> it's ok if you install classicshell
2015-02-09T14:33:09 < karlp> dongs: why the fuck would you need ssd for windows?
2015-02-09T14:33:40 < qyx_> i like the new feature - when you try to connect to wpa2 network and the metro fea..shit asks for password, windows uses your login credentials regardles of what you enter
2015-02-09T14:33:52 < qyx_> *wpa2 enterprise
2015-02-09T14:34:10 < PeterM> karlp, because windows is for people who value their time, not for people who spend days tweaking config files
2015-02-09T14:34:25 < Roklobsta> i hate the sneaky loginusingsomemicrosoft account.
2015-02-09T14:34:35 < dongs> Roklobsta: then dont use it
2015-02-09T14:34:41 < dongs> local accounts work just fine
2015-02-09T14:34:51 < PeterM> ^
2015-02-09T14:35:10 < Roklobsta> i don't. the numpties i help out with win 8 all get sucked into registering with MS just to log into their PC.
2015-02-09T14:35:14 < specing> PeterM: yes, but window's way of working makes it very easy to get malware... e.g. autorun on media
2015-02-09T14:35:31 < specing> and installing programs from all over the place
2015-02-09T14:35:55 < Roklobsta> i can't wair for metro and charms bar to fuck off in win10
2015-02-09T14:36:11 < PeterM> specing you till need to grant it elevated privledges to perform actions, just like on lunix
2015-02-09T14:36:16 < Roklobsta> legacy of balmer.
2015-02-09T14:38:16 < specing> PeterM: I doubt all malware needs elevated priviledges to run
2015-02-09T14:38:40 < PeterM> in the same case on lunix
2015-02-09T14:39:01 < Roklobsta> yep, malware can zap your personal files just fine.
2015-02-09T14:39:13 < Roklobsta> like the cretinous cryptolocker.

2015-02-09T15:03:35 < PaulFertser> Connected with jumper wires to L152 on a Nucleo board.
2015-02-09T15:07:03 < karlp> hrm, seems better than buying a jlink clone
2015-02-09T15:08:42 < PaulFertser> karlp: of course
2015-02-09T15:08:58 < PaulFertser> karlp: but probably if you have salea 16 it'd be even better ;)
2015-02-09T15:09:23 < PaulFertser> Yeah, no idea if trace will be supported with jlinks anytime soon.
2015-02-09T15:09:56 < karlp> I have a logic16 clone, didn't work with sigrok lasttime I tried, they might have figured it out now.
2015-02-09T15:10:08 < PaulFertser> karlp: but you can connect another random ft2232 device, it's not necessary to use only one debugging. You can debug with stlink or jlink and capture with an ft232h breakout board.
2015-02-09T15:10:23 < karlp> yeah, was hopign to avoid having two dongles if possible
2015-02-09T15:10:55 < karlp> swd+swo fast would be nice, but I also just want something that can do jtag with a few convenient headers for random probing shit
2015-02-09T15:11:06 < PaulFertser> But with logic16 one should be able to capture the trace in 4-bit sync mode even; I know you're not interested in that :)

Any buck boost small SIP's that I have seen do not deliver the required current for peak loads in Zano or require external components such as inductor.

2015-02-09T16:19:40 < jpa-> i guess (without seeing what R2COM writes) that he is talking about how you need less tests if the RF module already comes with a few certificates; which is true, but not sure if that is really such a big cost difference

2015-02-09T23:58:45 < PeterM> tectu if you are ok wiht same IC 4 times, thats pretty straight forward, you just swap the diode and inductor position

2015-02-10T00:01:00 < qyx_> it seems that people have the same problem with freertos failing with hardfault even when using timecube

2015-02-10T01:42:01 < KreAture_> it serves a real purpose
2015-02-10T01:42:06 < KreAture_> the product is entirely sealed
2015-02-10T01:42:20 < KreAture_> and no comms are exposed outside to avoid fiddling
2015-02-10T01:42:38 < KreAture_> but it "listens" on IR that is powerfull enough to penetrate the casing
2015-02-10T01:42:56 < KreAture_> only if you know how strong it needs to be and where to direct it though
2015-02-10T01:43:01 < KreAture_> Then there's encryption

2015-02-10T04:40:01 < dongs> cuz when I export gko it has those circles and shit
2015-02-10T04:40:04 < dongs> instead of just board outline
2015-02-10T04:40:13 < dongs> i know, I could just do board outline in another layer but im so damn lazy
2015-02-10T04:40:18 < ds2> oh
2015-02-10T04:40:22 < dongs> theres a better way to do it im sure
2015-02-10T04:40:41 < ds2> you want NO copper around the mounting hole, right?
2015-02-10T04:40:45 < dongs> right
2015-02-10T04:40:56 < ds2> isn't that defined by copper to edge rule?
2015-02-10T04:40:56 < dongs> and no mask
2015-02-10T04:40:58 < dongs> no mask is easy
2015-02-10T04:41:30 < dongs> i was hoping to define all this in a single component
2015-02-10T04:41:33 < dongs> so I can just drop M3 mounting holes into pcb
2015-02-10T04:41:44 < dongs> and not care about customizing design rules and shit for each time i do this
2015-02-10T04:41:58 < ds2> is the copper distance different then copper distance to edge of board?
2015-02-10T04:42:05 < ds2> for mtg hole
2015-02-10T04:42:51 < dongs> well, mounting is like 1 mm pullback
2015-02-10T04:42:56 < dongs> around 3mm hole
2015-02-10T04:42:59 < dongs> so it ends up 5mm diameter
2015-02-10T04:43:08 < dongs> but of course edge to copper is more like 0.2mm or wahtever

2015-02-10T04:47:32 < dongs> cue in R2COM how this is so easy to do in oorcad
2015-02-10T04:50:20 < ds2> it is so easy to do in eagle ;)
2015-02-10T04:55:18 < dongs> bashing your head against the wall is even easier in eagle
2015-02-10T04:55:29 < dongs> R2COM: do tell
2015-02-10T04:56:19 < dongs> yeah of what?
2015-02-10T04:56:31 < dongs> how do you specify copper pullback
2015-02-10T04:56:39 < dongs> 1mm no copper area around mounting hole
2015-02-10T04:57:20 < dongs> yes
2015-02-10T04:57:27 < dongs> no, hole in npth
2015-02-10T04:57:32 < dongs> so there's no copper
2015-02-10T05:05:41 < dongs> yeah, thats waht ive been doing

2015-02-10T05:27:11 < dongs> However, Altium Designer provides a powerful .Advanced (Query). method with which you define the clearance rule between A and B.
2015-02-10T05:27:14 < dongs> see??
2015-02-10T05:28:27 < dongs> you could write a query in Turbo Pascal
2015-02-10T05:28:30 < dongs> to define copper  clearance
2015-02-10T05:28:39 < dongs> if hole is > 1mm size for example
2015-02-10T05:28:44 < dongs> thats very pro

2015-02-10T06:56:16 < dongs> just ordered 5k of VLF3010 2.2uH coils, $466 total. fuck zano and LDOs
2015-02-10T06:56:58 < emeb_mac> that's a lot
2015-02-10T06:57:05 < dongs> makin' 5k dildos
2015-02-10T06:57:17 < emeb_mac> for ncp switchers?
2015-02-10T06:57:26 < dongs> no, tps63001 buckboost
2015-02-10T06:57:31 < emeb_mac> aha
2015-02-10T06:58:22 < emeb_mac> fuckboost
2015-02-10T06:58:32 < emeb_mac> hence dildos I suppose
2015-02-10T06:58:43 < dongs> nrf51822 is ~$8k
2015-02-10T06:58:51 < dongs> not a bad deal, can make lots of arduinos
2015-02-10T06:59:07 < dongs> cheaper than STM32 even if I dont use BT part of it
2015-02-10T07:00:21 < emeb_mac> those tps good for battery power?
2015-02-10T07:00:36 < dongs> ya
2015-02-10T07:00:57 < emeb_mac> autoswitching seems like
2015-02-10T07:01:08 < dongs> iq was something liek 50uA or someshit
2015-02-10T07:01:37 < emeb_mac> yep
2015-02-10T07:01:53 < dongs> previous dildo design sucked, motor was directly off lipo and it would get slower as battery drained
2015-02-10T07:02:36 < dongs> 'personal medical products' haha in TI suggested applications
2015-02-10T07:02:42 < dongs> they;re not far off!

2015-02-10T07:05:02 < dongs> its designed in altium

2015-02-10T08:27:24 < dongs> < wolfmanjm> dongs: I seriously suspect your experience in such things.... the STM HAL is the best I have seen in any pf the arm space
2015-02-10T08:27:27 < dongs> holy shit
2015-02-10T08:27:31 < dongs> braking news guys
2015-02-10T08:27:35 < dongs> stm32cube is amazing
2015-02-10T08:30:05 < englishman> sounds like someone opened it and poked around but didnt actualy make anything
2015-02-10T08:30:43 < jpa-> luls, wolfmanjm
2015-02-10T08:30:47 < dongs> < wolfmanjm> I totally disagree the HAL is well written, supportes three version of blockin and non blocking with interrupts and DMA far better than anything else I have seen. I suspect you think MBed is good then?
2015-02-10T08:31:21 < zyp> heh
2015-02-10T08:31:25 < jpa-> "smoothieware is not badly written, it is just full of race conditions!"
2015-02-10T08:32:24 < dongs> oh, you know the guy?
2015-02-10T08:32:30 < jpa-> yes
2015-02-10T08:32:34 < dongs> is he a pro?
2015-02-10T08:32:42 < jpa-> well he is clearly above my level
2015-02-10T08:33:12 < dongs> troll or srs
2015-02-10T08:33:18 < zyp> level of incompetence?
2015-02-10T08:33:35 < jpa-> well according to him
2015-02-10T08:33:43 < jpa-> i haven't yet decided which one of us is wrong
2015-02-10T08:33:51 < jpa-> but i couldn't get along with him

2015-02-10T08:34:51 < jpa-> < wolfmanjm> I think I can get defensive, I have every reason to, I spend a lot of time working on gettin gabort to work better than it did, and all you guys can do is piss vinegar on it...  that is not very helpful, you haven;t even looked to see how hard it is to do
2015-02-10T08:34:56 < jpa-> he got angry when i wasn't happy
2015-02-10T08:36:33 < dongs> whats gabort
2015-02-10T08:36:50 < jpa-> "abort file" in the smoothie cnc control thingie
2015-02-10T08:37:07 < englishman> wat chan is this
2015-02-10T08:37:23 < jpa-> it used to have 15 seconds delay, then he fixed it so that it stops immediately after a couple of random moves; but now he has actually fixed it correctly :)
2015-02-10T08:38:13 < jpa-> but yeah, i think he does know some stuff and does a lot of things but wouldn't call a pro
2015-02-10T08:38:32 < jpa-> and his personality clashes a lot with mine ;)
2015-02-10T08:38:33 < dongs> well he's already in negative rep points for liking timecube
2015-02-10T08:38:52 < jpa-> but look, he comes from mbed
2015-02-10T08:39:25 < jpa-> the library where you need to worry how many bytes of RAM a "Pin" class uses
2015-02-10T08:39:58 < dongs> http://robertmoorejr.tumblr.com/post/110101466091/im-an-anti-braker
2015-02-10T08:40:01 < jpa-> once he discovers raw register access on STM32 he'll be very happy
2015-02-10T08:40:08 < jpa-> suddenly everything except i2c is logical :)

2015-02-10T12:54:38 < Tectu> dongs, thanks!
2015-02-10T12:54:46 < Tectu> Laurenceb_, lets build one.
2015-02-10T12:55:05 < Laurenceb_> I'm realeasing my code on github
2015-02-10T12:55:18 < Laurenceb_> but atm the Rx only gives invalid preamble errors
2015-02-10T12:55:31 < Laurenceb_> itd help if there was a decent datasheet for it :-/
2015-02-10T12:56:03 < Getty> stupid question, is there actually an "idiot tool" which i could give customer to let him use the ST-Link to deploy new stuff on the device? Like really just a "Drop BIN file here" thing or something straightforward
2015-02-10T12:56:23 < Getty> thinking about giving the dealer a bit more power, but would only make sense if its simple for him
2015-02-10T12:56:30 < PaulFertser> OpenOCD with a premade script ;)
2015-02-10T12:56:33 < Laurenceb_> Getty: I made a bluetooth/.net thingy for that
2015-02-10T12:56:45 < Getty> yeah ;) i mean ... he is a "normal user"..... :) so openocd drops out a bit
2015-02-10T12:56:56 < Getty> (or i invest time to prepare something for him, but thats specific what i want to avoid)

2015-02-10T12:57:59 < Getty> Laurenceb_: show me :) if its free! :D
2015-02-10T12:58:47 < jpa-> openocd with a premade script is the simplest to prepare
2015-02-10T12:59:57 < jpa-> i have myself used usb bootloader for same purpose, but it took a few days to prepare the flashing program so that it will happily work with various windows versions
2015-02-10T13:00:03 < jpa-> especially driver installation is annoying

2015-02-10T13:02:41 < Getty> PaulFertser: SOUNDS simple but that would mean that he has to prepare the file at the right position with the right name so that the script takes it on ;)))) hehe

2015-02-10T13:05:54 < dongs> PaulFertser: does that code include some manchester decodeing stuff
2015-02-10T13:05:59 < PaulFertser> Getty: actually, stlink v2-1 comes with mass storage support, you just drop file there and it's flashed.
2015-02-10T13:06:05 < dongs> or does stlink handle that intertnally
2015-02-10T13:06:15 < Getty> PaulFerster: UH! cool.... didnt knew
2015-02-10T13:06:31 < PaulFertser> dongs: stlink can't handle manchester, only uart. The code can configure manchester but I don't have an LA yet to capture and decode it.

2015-02-10T13:26:13 < Tectu> okay*
2015-02-10T13:26:27 < Tectu> afaik all the MCU datasheets always mention to keep it CLOSE and SAME LENGTH :D
2015-02-10T13:26:30 < Tectu> might be wrong, tho
2015-02-10T13:26:44 < jpa-> too long causes trouble, because it'll add parasitic L & C, but other than that not so much
2015-02-10T13:26:54 < zyp> well, it is pretty close
2015-02-10T13:26:55 < jpa-> i guess that means like "don't run the other track around the board"
2015-02-10T13:26:57 < Tectu> good to know
2015-02-10T13:27:21 < jpa-> though at that point, i'm not sure if running both tracks around the board would make it any better
2015-02-10T13:28:00 < zyp> also, if the length difference mattered, the crystal wouldn't have the pads situated so far apart :p

2015-02-10T13:35:48 < zyp> fairly inexpensive while being decent
2015-02-10T13:36:04 < Tectu> if I would ever go into photography it would be macro photography

2015-02-10T13:37:26 < zyp> why can't you? that lens is inexpensive, and a dslr body isn't that much nowadays either
2015-02-10T13:37:46 < Tectu> for a student it surely still is too much :)
2015-02-10T13:37:57 < Tectu> also I tend to take crappy images

2015-02-10T13:41:10 < jpa-> total money i have spent on cameras in my life: 300 FIM in the 90s, 100 EUR a few years back
2015-02-10T13:41:35 < jpa-> but then again, i'm the limiting factor in my photo quality
2015-02-10T13:41:41 < Tectu> same here
2015-02-10T13:42:22 < dongs> back from dicktouch
2015-02-10T13:42:35 < zyp> I'm not sure I want to count how much I've spent on stuff
2015-02-10T13:43:27 < zyp> actually, not that horribly much
2015-02-10T13:43:52 < Tectu> just don't get a gf
2015-02-10T13:43:59 < Tectu> 14th is coming up I just realized
2015-02-10T13:44:01 < Tectu> why did nobody tell me
2015-02-10T13:44:02 < zyp> at this point I have three decent lenses, a decent flash and I'm on my second camera body
2015-02-10T13:44:14 < dongs> zyp, now all you need is raspberyypi 2
2015-02-10T13:44:20 < zyp> heh
2015-02-10T13:45:20 < zyp> I've also bought a couple of cheap lenses, that I'm not using, which I'm not sure where are anymore :p
2015-02-10T13:45:31 < zyp> and a bunch of other random bullshit
2015-02-10T13:47:07 < dongs> speaking of random bullshit, don't you want some more wires? :)
2015-02-10T13:47:11 < dongs> jk, china's closed anyway
2015-02-10T13:47:36 < zyp> the decent lenses are the 17-55/2.8 and 70-200/2.8 IS, in addition to the 60mm macro
2015-02-10T13:47:39 < Tectu> how long is china closed again?
2015-02-10T13:47:46 < zyp> actually bought all of them in jp, on three different trips
2015-02-10T13:48:10 < Tectu> zyp, out of curiousity: are genuine lenses cheaper there?
2015-02-10T13:48:12 < dongs> until end of feb
2015-02-10T13:48:14 < dongs> they're fucked
2015-02-10T13:48:14 < zyp> first camera body was a 30D, and then I bought a 60D to replace it after I damaged the shutter
2015-02-10T13:48:24 < dongs> wtf
2015-02-10T13:48:27 < dongs> arent thoes like pro camerasr
2015-02-10T13:48:30 < Tectu> zyp, because here in switzerland the stuff that is actually produced here is more expensive here than outside of switzerland -.-
2015-02-10T13:48:44 < zyp> dongs, I think the term is «prosumer»
2015-02-10T13:48:56 < Tectu> today they are called 'hipstercams'
2015-02-10T13:49:01 < Tectu> (no offense, zyp)
2015-02-10T13:49:02 < dongs> oh
2015-02-10T13:49:08 < dongs> they're only $700 now
2015-02-10T13:49:11 < Tectu> those are the kinds of cams that make you become a prophotographer
2015-02-10T13:49:13 < dongs> i thought it was one of those $5000+ canon shits
2015-02-10T13:49:20 < zyp> the 60D was $999, ordered from the US
2015-02-10T13:49:20 < Tectu> dongs, no, that would be 5D etc.
2015-02-10T13:49:23 < dongs> right
2015-02-10T13:49:26 < zyp> in 2011
2015-02-10T13:49:34 < Tectu> 5D Mark-3 is about 3'500 USD I think
2015-02-10T13:49:39 < Tectu> body only?
2015-02-10T13:49:44 < zyp> obviously cheaper now if it's even available, should be a few generations old by now
2015-02-10T13:49:48 < zyp> yes
2015-02-10T13:50:33 < zyp> Tectu, when I bought the 17-55 in 2008, I paid around two thirds of what it would have cost me to buy it in norway
2015-02-10T13:50:46 < zyp> but the exchange rate was more favorable then than now
2015-02-10T13:50:53 < Tectu> I see
2015-02-10T13:50:57 < Tectu> so they are doing it right
2015-02-10T13:51:12 < zyp> main benefit is that I don't have to pay norwegian consumption tax of 25%
2015-02-10T13:51:15 < Tectu> my local friend bought a swiss watch while being on vacation just because it was cheaper there than here...
2015-02-10T13:51:25 < Tectu> 25%  ?!
2015-02-10T13:51:26 < Tectu> what?
2015-02-10T13:51:36 < zyp> yep
2015-02-10T13:51:48 < zyp> norwegian consumption tax is 25%
2015-02-10T13:52:23 < Tectu> wait..
2015-02-10T13:52:27 < Tectu> is that VAT?
2015-02-10T13:52:32 < Tectu> MwST in german?
2015-02-10T13:52:33 < zyp> yes
2015-02-10T13:52:39 < Tectu> cut that would be 8% here I think?
2015-02-10T13:52:53 < Tectu> does your government like money that much?
2015-02-10T13:53:06 < zyp> but when you're travelling, shit you bring with you from abroad is exempt up to 6000 NOK of value

2015-02-10T13:55:06 < zyp> I've been checked in norwegian customs once, and then the guy only cared about whether the alcohol I brought were over quotas, and whether I had any other drugs with me
2015-02-10T13:56:08 < zyp> that guy was a total asshole about it though
2015-02-10T13:56:11 < Tectu> zyp, why don't you go EUR?
2015-02-10T13:56:32 < zyp> maybe because we're not part of EU? :p

2015-02-10T13:58:10 < Tectu> but we fucked that up last year by saying that we don't want more than 8k immigrants a year LOL

2015-02-10T15:19:49 < PaulFertser> kakeman: then something along the lines "mingw-w64-i686-gcc <yourapp> -o <yourapp.exe>" should work iirc.

2015-02-10T15:26:37 < PaulFertser> kakeman: then just grab code::blocks with mingw and it'll all work ootb.

2015-02-10T19:33:40 < Steffanx> auto brightness is the worst feature ever invented, especially when the response to changes in light is too fast.
2015-02-10T19:36:44 < Laurenceb> no the si446x is the worst feature
2015-02-10T19:36:52 < Laurenceb> stupid pita
2015-02-10T19:37:56 < englishman> are you still trolling with that shit
2015-02-10T19:38:02 < englishman> are you at least modulating by now
2015-02-10T19:38:32 < Laurenceb> yeah its modulating
2015-02-10T19:38:38 < Laurenceb> not got any further tho
2015-02-10T19:38:57 < Laurenceb> i can get RSSI interrupts and preamble invalid interrupts
2015-02-10T19:39:08 < Laurenceb> but dunno how to fix it
2015-02-10T19:40:54 < Laurenceb> maybe i should grab the perl script from arduino land
2015-02-10T19:40:58 < Laurenceb> for configuring it
2015-02-10T19:41:12 < Laurenceb> https://github.com/Laurenceb/STM32_Launcher/commit/73b1ee72e792f7699d5e4b3e82e75939f3c4c944
2015-02-10T19:41:24 < Laurenceb> theres probably some difference between those two files... somewhere
2015-02-10T19:41:54 < Laurenceb> haha line9
2015-02-10T19:41:56 < englishman> which modulations?
2015-02-10T19:42:03 < Laurenceb> 2FSK
2015-02-10T19:42:09 < englishman> i found it much easier to start with simple ook or some shit and move up when shit worked
2015-02-10T19:42:24 < englishman> cuz theres a lot to dick up
2015-02-10T19:42:35 < Laurenceb> interesting idea
2015-02-10T19:42:37 < englishman> does it look ok on specan?
2015-02-10T19:42:43 < Laurenceb> yes its all 100%
2015-02-10T19:42:48 < englishman> then probably rx shit
2015-02-10T19:42:51 < Laurenceb> Tx modulation is fine
2015-02-10T19:42:52 < Laurenceb> yeah
2015-02-10T19:43:05 < englishman> so many settings without explanation or documentation
2015-02-10T19:43:20 < dongs> typical laurencesores
2015-02-10T19:43:25 < englishman> also started simple on packet shit and added more crap later on when it worked
2015-02-10T19:43:29 < englishman> no crc, etc
2015-02-10T19:43:29 < Laurenceb> it must be something basic and RSSI works but preamble doesnt
2015-02-10T19:43:38 < Laurenceb> that doesnt leave a lot in between
2015-02-10T19:44:00 < Laurenceb> s/and/as
2015-02-10T19:44:08 < emeb> radio is hard
2015-02-10T19:44:09 < englishman> um yeah theres a whole not

2015-02-10T19:44:18 < Laurenceb> really?
2015-02-10T19:44:21 < englishman> like, entire demodulation chain
2015-02-10T19:44:27 < Laurenceb> i thought RSSI was after the filter
2015-02-10T19:44:30 < Laurenceb> yeah i guess lol
2015-02-10T19:44:42 < Laurenceb> BCR and AFC and discriminator
2015-02-10T19:45:42 < Laurenceb> maybe silabs can help...

2015-02-10T21:44:56 < BrainDamage> 10g is like a large pinch
2015-02-10T21:44:57 < _Sync_> basically pro IRCers
2015-02-10T21:45:03 < _Sync_> try it.
2015-02-10T21:45:09 < _Sync_> it is super fucking bitter
2015-02-10T21:46:25 < kakeman> you are talkin about fatal overdose
2015-02-10T21:46:52 < BrainDamage> 10g would be fata for 50% of the individuals approx
2015-02-10T21:47:18 < BrainDamage> you'd likely see bad symptoms at much smaller fractions
2015-02-10T21:53:16 < Roklobsta> too much instant coffee is not a good idea.  i learned this at uni exam time.
2015-02-10T21:55:08 < englishman> any amount of instant coffee is a bad thing
2015-02-10T21:55:38 < synic> also, whatever you do, don't say to yourself, "hey, 1 vivarin worked so well, I'll take 4 next time"
2015-02-10T21:57:50 < kakeman> been there?
2015-02-10T21:57:55 < _Sync_> depends on your tolerance

2015-02-10T23:10:59 < Steffanx> you better download a complete "working" arduino library Laurenceb_

2015-02-11T01:25:48 < Getty> that awkward moment when the error messages of a website are so fancy that it takes a moment to realize its actually an error page: http://colorcharge.com/jquery/
2015-02-11T01:26:13 < karlp> that's a website runnign in debug mode.
2015-02-11T01:26:19 < _Sync_> wat
2015-02-11T01:26:32 < Getty> oh! ok, looked so error :)
2015-02-11T01:26:50 < karlp> it is an error, but it's running in debug mode.
2015-02-11T01:27:02 < karlp> you can probably even interact with the stack and so bad shit that shouldn't be on public websites
2015-02-11T01:27:06 < Getty> is it common to like autoswitch to debug mode for errors? (and so not having it else)
2015-02-11T01:27:21 < Getty> i mean symphony people are anyway crazy people ;)
2015-02-11T01:27:41 < karlp> like, you're looking at all their raw php code, you don't normally show people that
2015-02-11T01:30:09 < Getty> well i just see some lines that is pretty common error message concept in modern web frameworks
2015-02-11T01:30:22 < Getty> so overall this looks like error page alone, but if you say its debugging mode, then i know now :)

2015-02-11T06:17:49 < dongs> i am updating old schematic where i had all resistors in the schlib as 'res'
2015-02-11T06:18:07 < dongs> so anoying to change them to res0402 etc and then rename comment/value
2015-02-11T06:19:34 < PeterM> yer, one day i just sat down and made a whole bunch of res + caps for 0402/0603/0805/1206 E192 - was tedious and boring as batshit but now its done, tis done
2015-02-11T06:19:57 < dongs> eh, i didnt go that far
2015-02-11T06:20:01 < dongs> i have res0402/0603/etc
2015-02-11T06:20:06 < dongs> and I change comment + value
2015-02-11T06:20:11 < dongs> i know thats not the right way but
2015-02-11T06:20:24 < dongs> also, I bet you could have scripted that :)

2015-02-11T09:33:16 < dongs> zyp, have you tested your ft256 bga schema yet?
2015-02-11T09:33:23 < dongs> did you use SPI flash, or the xilinx bootrom trash
2015-02-11T09:42:06 < zyp> neither, it's slave loading from the stm32
2015-02-11T09:42:44 < zyp> since it's mapped to FSMC anyway, I wired it up for slave parallel, so I'm loading shit through FSMC
2015-02-11T09:45:43 < zyp> http://paste.jvnv.net/view/DxCwR <- so I just have a usb control request handler that controls the prog_b/csi_b lines and feeds data to one of the FSMC areas

2015-02-11T09:50:12 < zyp> that said, I'll not use slave parallel in next revision
2015-02-11T09:50:24 < zyp> I'll rather wire up slave serial to an SPI port
2015-02-11T09:53:11 < zyp> eventually, the stm32 will have an sd card or a usb stick for storage, so I might as well just load the bitstream for there, no need for a separate flash for the bitstream
2015-02-11T09:53:25 < zyp> from there*

2015-02-11T12:13:07 < dongs> holy balls
2015-02-11T12:13:14 < dongs> entire spartan6 selection is nonstock
2015-02-11T12:13:14 < karlp> zyp: what's that monstrous revbyte() routine doing exactly? reversing bits
2015-02-11T12:13:21 < zyp> yep
2015-02-11T12:13:25 < karlp> oh yeha, A is 0x82, which becomes 0x41. weird.
2015-02-11T12:14:30 < zyp> I'm doing it real lazy by converting the character to a binary string, padding it out to 8 bits, reversing it and converting it back to a character :p
2015-02-11T12:14:56 < zyp> I mean, a string representation of a binary number
2015-02-11T12:15:01 < dongs> well what hte hell
2015-02-11T12:15:09 < dongs> i guess  xilinx killed off spartan series completely
2015-02-11T12:15:35 < dongs> maybe its time to skillsurf over  to altera
2015-02-11T12:15:42 < zyp> in what sense? they're still not EOL?
2015-02-11T12:15:50 < dongs> in the sense that you cant buy them
2015-02-11T12:16:24 < zyp> but yeah, I've considered trying altera myself
2015-02-11T12:16:42 < zyp> hoping they'll have less bullshit to deal with
2015-02-11T12:16:43 < karlp> what's the story with the bitstream from the tools that you need to reverse the whole thing? not just the bytes themselves?
2015-02-11T12:16:56 < zyp> karlp, just the bytes

2015-02-11T15:22:56 < dongs> ok is there an easy way to move a pin to another net in layout and then  have it reflect that in schematic?
2015-02-11T15:23:38 < zyp> probably not
2015-02-11T15:24:19 < PeterM> nope
2015-02-11T15:24:30 < zyp> doesn't pins have a list of associated nets? you could probably change that and generate an ECN for layout -> schematic
2015-02-11T15:25:04 < PeterM> then oyu'd have to redraw that in your schem becuase i wouldnt auto redraw
2015-02-11T15:25:29 < zyp> the latter part must be possible to support pinswaps, and that's possible, no?
2015-02-11T15:26:17 < Laurenceb> wohoo
2015-02-11T15:26:19 < Laurenceb> I am delighted to inform you that following yesterday’s meeting, the Impact Acceleration Account panel has approved your application for a project

2015-02-11T15:26:55 < dongs> hurr yeah
2015-02-11T15:27:04 < dongs> I BET IT CAN BE SO EASY IN ORCAD
2015-02-11T15:27:07 < Laurenceb> unfunny balance in my bank account
2015-02-11T15:27:20 < dongs> that is entirely your fault
2015-02-11T15:27:44 < Laurenceb> i should try bullshitting more in future
2015-02-11T15:28:12 < dongs> The RGB display can pull over 100mA if running at full power. If your only displaying a count down then it draws about 8ma.
2015-02-11T15:28:15 < dongs> HAHA WHAT
2015-02-11T15:28:18 < jpa-> in kicad you could just do the same change in both and pray that they are in sync afterwards!
2015-02-11T15:28:26 < dongs> they got 1.5mA leds in there?
2015-02-11T15:29:01 < PeterM> jpa-, or you just  change in schem and push to pcb
2015-02-11T15:29:59 < dongs> god damn spartan6 bga layout is just completely fucking fucktarded
2015-02-11T15:30:05 < dongs> programming pins: in 3 fucking corners
2015-02-11T15:31:13 < jpa-> PeterM: yep, but it's not like the change is automatic in pcb anyway so you'd have to redraw on the pcb side also anyway
2015-02-11T15:31:46 < jpa-> which is nice in the way that when you know what you are doing, you can just edit the schem and pcb and check the sync later
2015-02-11T15:34:15 < PeterM> yerp
2015-02-11T15:36:28 < jpa-> hmm, i have some device with a cpu that looks like STM32, has ST logo but the text says "ES32F407".. any ideas what it might be? google doesn't seem to have anything
2015-02-11T15:36:40 < zyp> sounds like a weird F4
2015-02-11T15:36:48 < zyp> engineering sample F4? :p

2015-02-11T15:37:47 < jpa-> zyp: ah, might very well be

2015-02-11T15:38:30 < dongs> pics of top of  cpu is nda? :)(
2015-02-11T15:39:13 < jpa-> well taking photos of it might raise questions :P
2015-02-11T15:39:55 < jpa-> could also be some strange safety version of stm32, i don't even know what the device does
2015-02-11T15:40:53 < akaWolf> lol
2015-02-11T15:41:22 < akaWolf> we also have some TI engineering examples, named in different, but similar way
2015-02-11T15:41:45 < akaWolf> I think, ES32F407 -- STM32F407
2015-02-11T15:42:04 < jpa-> i don't know how long this has been in development, might very well be that they have got some engineering samples before stm32f407 was officially released
2015-02-11T15:42:15 < akaWolf> yeah
2015-02-11T15:42:30 < jpa-> so, best guess: full of errata :)
2015-02-11T15:42:40 < akaWolf> yeah
2015-02-11T15:43:07 < akaWolf> even not engineering chips from TI has many bugs
2015-02-11T15:44:03 < akaWolf> as I remember, ST too

2015-02-11T18:46:35 < zyp> how so?
2015-02-11T18:46:50 < emeb> the way they do buffer management
2015-02-11T18:47:11 < emeb> basically declares itself as a 22kHz sample rate
2015-02-11T18:47:20 < zyp> 44 you mean?
2015-02-11T18:47:32 < emeb> no 22
2015-02-11T18:47:41 < zyp> uh, wat
2015-02-11T18:47:42 < emeb> allocates a 22-sample buffer
2015-02-11T18:47:54 < emeb> then resets the pointers into the buffer every SOF
2015-02-11T18:48:19 < emeb> so if the output DAC isn't done playing the buffer when the next SOF happens - oh well.
2015-02-11T18:48:19 < zyp> weird
2015-02-11T18:48:35 < zyp> and yeah
2015-02-11T18:49:09 < zyp> probably better than my usb audio code though
2015-02-11T18:49:27 < emeb> I remember you did some work with that a few years ago
2015-02-11T18:50:11 < zyp> yeah
2015-02-11T18:50:57 < zyp> I just have the usb code put the data into a ringbuffer with circular dma feeding i2s
2015-02-11T18:51:01 < zyp> no sync at all
2015-02-11T18:51:27 < emeb> any under/over-flow issues?
2015-02-11T18:52:01 < zyp> yeah, since I can't generate the exact required i2s clock rate
2015-02-11T18:52:33 < emeb> IIRC there is a handshake technique to manage that, but I don't remember the details
2015-02-11T18:53:20 < zyp> there's a couple of methods
2015-02-11T18:53:39 < zyp> I tried adding a synch feedback endpoint, but I couldn't get that to work properly
2015-02-11T18:55:25 < jpa-> akaWolf: in what? typically you define entry point with -e to linker in gcc
2015-02-11T18:55:42 < jpa-> akaWolf: though for cortex-m, all that matters is what the vector table says
2015-02-11T18:57:02  * Laurenceb has a weird bug with his silabs code
2015-02-11T18:57:23 < Laurenceb> silabs register read only works if the read routine isnt called from an interrupt
2015-02-11T18:58:41 < Laurenceb> if interrupts have the same preemption priority and different subpriorities they cant nest right?
2015-02-11T18:59:31 < PaulFertser> Right

2015-02-11T19:00:39 < Laurenceb> it reads all ones or all zeros
2015-02-11T19:00:44 < karlp> random question, if you wanted to record a 2 hour meeting, from a alptoip with a usb mic, what software is worth using?
2015-02-11T19:00:57 < karlp> ie, recording straight to wav is going to be a bit silly
2015-02-11T19:01:12 < Laurenceb> but if i call si446x_spi_state_machine it runs fine

2015-02-11T19:08:03 < emeb> zyp: slightly better way to manage buffers is to reset output ptr @ every received pkt
2015-02-11T19:08:33 < zyp> yeah
2015-02-11T19:08:41 < emeb> that may lose/gain a sample as packet rate slips past the output rate
2015-02-11T19:09:13 < emeb> but their method can lose multiple samples every packet since SOF timing isn't aligned with when the packet arrives
2015-02-11T19:09:37 < zyp> well
2015-02-11T19:10:17 < zyp> SOF rate should be fairly consistent, packets might jitter around a fair bit
2015-02-11T19:10:34 < zyp> so timing by SOF is better than timing by packet
2015-02-11T19:11:22 < zyp> and then you need some buffer area in between to account for packet timing jitter
2015-02-11T19:12:03 < zyp> two buffers, one to read and one to write during every frame, then switch them on SOF
2015-02-11T19:13:37 < akaWolf> jpa-: I just found it in our Makefile, and without it gcc failed
2015-02-11T19:14:17 < akaWolf> it's fact: gcc have some internal defines
2015-02-11T19:14:35 < akaWolf> looks like it's one of them
2015-02-11T19:15:53 < jpa-> no hits for grep -r in your source code? gcc failed how?
2015-02-11T19:18:07 < jpa-> grep -r ENTRY returns 0 hits on GCC source it seems to me

2015-02-11T19:31:37 < zyp> pretty much the same thing, really
2015-02-11T19:31:58 < emeb> I guess so
2015-02-11T19:32:04 < zyp> you just swap all references to IN/OUT in descriptors and endpoints
2015-02-11T19:32:30 < emeb> still isochronous
2015-02-11T19:32:39 < emeb> so buffers/frame = constant
2015-02-11T19:33:16 < emeb> and unfortunately frame rate is defined by host, not local timing
2015-02-11T19:34:32 < zyp> this reminds me about the LPC chips
2015-02-11T19:34:39 < emeb> ?
2015-02-11T19:34:44 < zyp> they can tune the SOF rate in host mode

2015-02-11T19:36:16 < jpa-> for slave mode, i guess just tune the adc / codec sample clock dynamically?
2015-02-11T19:36:28 < zyp> yeah, if you can

2015-02-11T19:36:58 < jpa-> (and that could damage the alien probe)
2015-02-11T19:37:09 < emeb> tweaking codec sample rate is pretty tricky on most architectures
2015-02-11T19:38:17 < emeb> some architectures designed for this have PLL with steering capability
2015-02-11T19:38:21 < emeb> but that's unusual
2015-02-11T19:38:36 < emeb> some do it with DSP ASRC
2015-02-11T19:39:18 < emeb> but audiophools hate that - "It's not the original samples!"

2015-02-11T19:39:25 < jpa-> on STM32 if using ADC, you could do it by tweaking the timer
2015-02-11T19:39:53 < emeb> yup - just need a control loop based on incoming data.

2015-02-11T21:23:31  * emeb doesn't hold bref
2015-02-11T21:24:00 < emeb> 900km sounds... ambitious.
2015-02-11T21:24:13 < Laurenceb> yeah its not needed
2015-02-11T21:24:24 < Laurenceb> but i do get 40dB fade margin at 100km
2015-02-11T21:24:31 < PaulFertser> What's declared sensitivity of that chip?
2015-02-11T21:24:33 < Laurenceb> so it should work in real life
2015-02-11T21:24:38 < Laurenceb> -128dBm
2015-02-11T21:25:00 < Laurenceb> but im running it in 200bps with AFC and dual 500hz filters
2015-02-11T21:26:43 < Laurenceb> so should be ~10dB better than the quoted figure for 500bps and 2kHz filter with no AFC
2015-02-11T21:26:52 < emeb> narrow band. should be good.
2015-02-11T21:27:09 < PaulFertser> What band is that? SW? 200bps on 900km sounds rather impressive.
2015-02-11T21:27:17 < emeb> next up - hoping there's no one else on your channel
2015-02-11T21:27:18 < Laurenceb> theres a few hundred Hz of AFC on the chip

2015-02-11T21:35:42 < Laurenceb> yeah

2015-02-11T21:35:55 < emeb> that's just wishful thinking
2015-02-11T21:36:06 < Laurenceb> it will still have >20dB fade margin at the horizon
2015-02-11T21:36:08 < BrainDamage> that's current distances obtained by guys in ##highaltitude

2015-02-12T00:33:34 < kakeman> what you doing?
2015-02-12T00:34:03 < KreAture_> adjusting the design of my stepper boards
2015-02-12T00:34:15 < KreAture_> adding digipot to avoid user shorting stuff out when adjusting current
2015-02-12T00:35:21 < KreAture_> MCP4532 seems like a good one
2015-02-12T00:35:49 < KreAture_> It can take a 3 bit address via the connector so I can have each of the stepper 8 slots code a different address
2015-02-12T00:36:03 < kakeman> is it best way to go with dedicated stepper controllers?
2015-02-12T00:36:14 < KreAture_> ?
2015-02-12T00:36:21 < Laurenceb_> depends if you want to play with fire
2015-02-12T00:36:32 < KreAture_> My board has support for 8
2015-02-12T00:36:45 < KreAture_> and they are external to the board as you can fit different ones for different uses
2015-02-12T00:36:50 < KreAture_> even 20 amp ones
2015-02-12T00:37:33 < KreAture_> My normal ones are 3-4 amps max
2015-02-12T00:40:33 < kakeman> I would personally go with non stepper controller but never done stepper driver
2015-02-12T00:40:34 < KreAture_> digitally programmed addresses would be ok too, if I could be sure to set the tight one
2015-02-12T00:40:36 < KreAture_> hehe
2015-02-12T00:40:44 < KreAture_> non stepper ?
2015-02-12T00:40:47 < KreAture_> wetf
2015-02-12T00:40:53 < KreAture_> wtf?
2015-02-12T00:41:06 < KreAture_> For 3d printers stepper control is nice
2015-02-12T00:41:16 < KreAture_> and not having to fiddle with duty cycles is what it's all about
2015-02-12T00:41:25 < KreAture_> especially at high step rates

2015-02-12T12:15:22 < jpa-> umm, because it is a function?
2015-02-12T12:15:40 < jpa-> the way gcc does unwinding in arm is to have unwind info for any complex function
2015-02-12T12:16:06 < jpa-> i think that is usually "any function that pushes the frame pointer" but might be wrong
2015-02-12T12:16:35 < jpa-> you can see that udivdi3 has 0 bytes of unwind data, while divdi3 has 8 bytes; i wouldn't be surprised if divdi3 calls udivdi3

2015-02-12T12:47:38 < zyp> dongs, how much would you estimate a set of 4L protos cost, assembled?
2015-02-12T12:47:54 < zyp> say 6x9cm or so
2015-02-12T12:48:04 < zyp> (BOM cost excluded, of course)
2015-02-12T12:48:17 < dongs> what kinda stuff?
2015-02-12T12:48:18 < dongs> workshit?
2015-02-12T12:48:30 < zyp> F4, ethernet phy, power, couple of connectors
2015-02-12T12:48:39 < zyp> yeah, it's the thing I mentioned a couple of weeks ago
2015-02-12T12:49:37 < zyp> having a meeting with the guys in a moment, and they'll probably going to ask me how much it'll cost and how much time I'm going to need, so having some ballpark figures would help :p
2015-02-12T12:50:26 < dongs> doesnt make it any more expensive because 4L assembly-wise, but if its like ~10 or someshit boards I can just do them same way I did those header boards
2015-02-12T12:50:29 < dongs> i.e. cheap
2015-02-12T12:50:33 < zyp> I'm figuring that we'll want a prototype run before any sort of volume production, and I'm thinking I don't want to assemble the protos myself
2015-02-12T12:50:51 < dongs> yeah sure, so I can do that, proto 4L is really rapey tho
2015-02-12T12:51:07 < dongs> as in 10 proto =~ full m^2 price
2015-02-12T12:51:24 < zyp> what's the ballpark figure on that?
2015-02-12T12:51:54 < dongs> lemme see wat the last few were for small size
2015-02-12T12:52:34 < zyp> hmm, I guess a reasonable way to handle it would be to get a bunch of boards, but only assemble a few protos first
2015-02-12T12:52:41 < dongs> right
2015-02-12T12:52:45 < dongs> i would suggest that for sure
2015-02-12T12:52:48 < dongs> unless  you plan to fuck up

2015-02-12T12:55:36 < zyp> I'm not sure the design really requires 4L either, but I'm not making that decision until I'm ready to begin layout

2015-02-13T13:11:01 < jpa-> what does "being ready for desktop" mean anyway?
2015-02-13T13:11:11 < jpa-> would it have to always work 100% and never have any problems?
2015-02-13T13:11:35 < dongs> it would have to be usable

2015-02-13T13:13:24 < dongs> jpa, i turn it on, and it works.
2015-02-13T13:13:29 < dongs> i unplug it, and plug it back in, and it still works

2015-02-13T13:45:59 < qyx_> for sure they are costly if average user needs 2TB of torrented bluray movies
2015-02-13T13:46:14 < zyp> it was talk about application startup time
2015-02-13T13:49:34 < akaWolf> even for using as system drive, ssd is too costly...
2015-02-13T13:49:46 < zyp> no, it's not
2015-02-13T13:49:50 < zyp> ssd is cheap as fuck
2015-02-13T13:50:00 < akaWolf> you are norvegian :P
2015-02-13T13:50:51 < akaWolf> price of 2 tb hdd = price for 80 gb ssd
2015-02-13T13:50:56 < akaWolf> cheap?
2015-02-13T13:51:33 < akaWolf> like so...
2015-02-13T13:51:40 < zyp> yeah, 2tb hdds are also cheap as fuck nowadays
2015-02-13T13:52:00 < akaWolf> well, if it's all cheap for you, then yes
2015-02-13T13:52:05 < akaWolf> but for me -- no :)
2015-02-13T13:52:55 < jpa-> i'm doing just fine with 24GB SSD as system drive, i doubt it added much to the price of the laptop
2015-02-13T13:53:07 < akaWolf> hm
2015-02-13T13:53:09 < akaWolf> yeah
2015-02-13T13:53:20 < akaWolf> but in Windows I need much more
2015-02-13T13:53:26 < akaWolf> place for system drive
2015-02-13T13:53:48 < jpa-> so because windows needs more, that's a reason why application startup time in linux without ssd is a problem? :)
2015-02-13T13:54:14 < akaWolf> I'm not talking about startup, just about cost of ssd :)
2015-02-13T13:55:01 < zyp> you can get fairly big SSDs for less than $100 nowadays
2015-02-13T13:55:34 < akaWolf> yeah, but it's not cheap for me
2015-02-13T13:55:36 < akaWolf> :)
2015-02-13T13:55:39 < Steffanx> in this country an SSD is only about 10-15x more expensive per GB :)
2015-02-13T13:56:00 < zyp> akaWolf, what are you comparing to when you say it's not cheap?
2015-02-13T13:56:37 < akaWolf> now relatively cheap for me is about 3000rub ~ $50
2015-02-13T13:57:51 < zyp> I mean, cheap is relative
2015-02-13T13:58:00 < dongs> < akaWolf> even for using as system drive, ssd is too costly...
2015-02-13T13:58:01 < dongs> wut
2015-02-13T13:58:01 < akaWolf> yeah
2015-02-13T13:58:07 < dongs> in even using SSD as a scratch drive

2015-02-13T13:59:01 < dongs> OS is 160? i think or 180 and 64 for scratch

2015-02-13T14:00:13 < scrts_w> was funny when it was 100rub/1usd :)))
2015-02-13T14:00:16 < dongs> is that good or bad?
2015-02-13T14:00:23 < akaWolf> scrts_w: it wasnt funny.

2015-02-13T14:00:28 < zyp> I think I've got just over half a terabyte of ssds in all
2015-02-13T14:00:50 < scrts_w> akaWolf: but what's the situation in your country? everything is getting back to better life now?
2015-02-13T14:02:51 < akaWolf> scrts_w: nothing getting better now... if you mean a period, when $1 = 100rub, we did not notice that, becouse it was for very short time
2015-02-13T14:02:52 < PaulFertser> scrts_w: lol, why?
2015-02-13T14:03:18 < scrts_w> akaWolf: well I thought compared to that period... should be getting better now
2015-02-13T14:03:34 < scrts_w> I've heard that the economy isn't going really well, but it isn't THAT BAD?
2015-02-13T14:04:12 < akaWolf> since, there was only on bourses, we did not notice that...
2015-02-13T14:04:22 < PaulFertser> Not that bad, no. But it still sucks and is likely to get worse.
2015-02-13T14:04:42 < akaWolf> just smooth rising in prices
2015-02-13T14:04:47 < Steffanx> All because of the oil price and the US/EU with their "screw russia" attitude?
2015-02-13T14:05:09 < akaWolf> about 80% becouse of oil
2015-02-13T14:05:18 < akaWolf> and 20% of EU
2015-02-13T14:05:25 < zyp> the oil price affected NOK pretty bad too
2015-02-13T14:05:29 < Steffanx> 100% putin :P
2015-02-13T14:05:34 < scrts_w> haha :)
2015-02-13T14:05:47 < scrts_w> I think russians still love Putin no matter what
2015-02-13T14:05:55 < akaWolf> they are love.
2015-02-13T14:06:10 < zyp> but I profited fairly well of the current USD/NOK rate, since I sold a bunch of shit for USD :p

2015-02-13T14:06:35 < specing> that is like ... atleast 40% more than most western politicians

2015-02-13T14:07:05 < scrts_w> you just fake the elections and that's it... isn't it?
2015-02-13T14:07:14 < scrts_w> like Belarus guy do...
2015-02-13T14:07:19 < scrts_w> Lukashenka right?
2015-02-13T14:07:32 < specing> scrts_w: I think Putin controls the mass media, no need to fake elections
2015-02-13T14:07:33 < Steffanx> o
2015-02-13T14:07:35 < Steffanx> not a
2015-02-13T14:07:41 < akaWolf> yeah, it's really no need

2015-02-13T14:07:54 < scrts_w> oh cool :)
2015-02-13T14:07:56 < specing> Lukashenko the last dictator of europe
2015-02-13T14:08:06 < specing> now challenged by Orban of hungary
2015-02-13T14:08:54 < PaulFertser> I've talked to my fellow yesterday, he's a smart guy, working at a university. Says he's glad now "they got some respect for Russia" and that "now we can decide on our own how to live, no more western dictate", and that it's all very encouraging in his opinion.
2015-02-13T14:09:34 < akaWolf> I'm afraid, he isnt so smart
2015-02-13T14:10:08 < PaulFertser> He's a nice guy though. But probably yes...
2015-02-13T14:10:15 < scrts_w> PaulFertser: heh... well, they see Europe as Gayrope
2015-02-13T14:10:17 < akaWolf> well, IQ isnt only one index
2015-02-13T14:10:28 < scrts_w> like everyone here would fuck in the ass and always raped
2015-02-13T14:10:36 < karlp> on national leader support, iceland's PM is down to about 10% suppoort. pirate party has ~11%
2015-02-13T14:11:24 < PaulFertser> He also said that not being able to use your preferred language at public schools (as was actually the case with some russian-speaking ukrainians) is enough of a reason to fight with weapons.
2015-02-13T14:12:34 < PaulFertser> Sigh
2015-02-13T14:12:58 < akaWolf> very stupid sentence.
2015-02-13T14:13:09 < scrts_w> :)))
2015-02-13T14:13:24 < specing> PaulFertser: yes, in most civilised countries, cities/towns with big minorities have dual-language stuff
2015-02-13T14:13:30 < dongs> d o g e
2015-02-13T14:13:40 < scrts_w> ok, but do Russians believe, that the army has been sent to fight in Ukraine? Also tanks and all that artilery stuff is also from Russia?
2015-02-13T14:13:53 < akaWolf> I think, no
2015-02-13T14:13:58 < scrts_w> big minorities, cool
2015-02-13T14:14:03 < PaulFertser> I do not like europe bureaucracy either. I do not like USA's hypocrisy. Damn, why the world's so sick?!
2015-02-13T14:14:10 < akaWolf> my known lives in Mariupol
2015-02-13T14:14:17 < specing> scrts_w: not sure how to properly say that
2015-02-13T14:14:30 < scrts_w> specing: that's correct, just sounds interesting :)
2015-02-13T14:14:35 < akaWolf> he talk me, that there is no russians in Ukraine
2015-02-13T14:14:52 < specing> scrts_w: regions with a lot of native speakers of some foreign language
2015-02-13T14:14:56 < Steffanx> only russian tanks/weapons akaWolf? ;)
2015-02-13T14:15:25 < PaulFertser> scrts_w: I think most russians sincerely deny any regular army participation, they think those fighting are all volunteers, and russia is only giving food and clothes to the "oppressed regions".
2015-02-13T14:15:39 < specing> Steffanx: that is hard to say, some of "russian weapon" production was always located in ukraine
2015-02-13T14:15:51 < scrts_w> where did Poroshenko get a bunch of Russian soldier passports and army IDs in Munchen?
2015-02-13T14:15:58 < specing> and certainly ukraine has been buying military gear from russia in the past
2015-02-13T14:16:16 < scrts_w> specing: well that's true...
2015-02-13T14:16:16 < PaulFertser> scrts_w: why didn't he only showed it and then provide no further evidence, no independent expertise etc?
2015-02-13T14:16:29 < PaulFertser> The problem here is everyone's such a fucking lier.
2015-02-13T14:16:35 < scrts_w> except Ukraine had T72 tanks, while most of the tanks there are T70 I think there... used by Russia
2015-02-13T14:16:49 < Steffanx> Not only there PaulFertser. Here screw over with the airplane crash in ukraine is still dominating the daily news over here.
2015-02-13T14:16:56 < Steffanx> and they seem to lie about it a lot
2015-02-13T14:17:05 < specing> scrts_w: did he submit them to some "unbiased" forensic team for authenticy checking?
2015-02-13T14:17:08 < akaWolf> Steffanx: dont know about weapons, but about army -- no.
2015-02-13T14:17:11 < scrts_w> yeah... that's a huge mess with the plane too
2015-02-13T14:17:12 < PaulFertser> Why don't the USA publish any proof to clear the Boeing dispute?!
2015-02-13T14:17:22 < Steffanx> meh, that sentence doesn't even parse here ( my own sentence that is )
2015-02-13T14:17:26 < scrts_w> btw, no black box recordings either? :)
2015-02-13T14:17:43 < PaulFertser> Steffanx: yes, my thoughts exactly. All them damn liers.
2015-02-13T14:21:57 < Cyric_> guys i have a problem with a ftdi adapter.... basically it load and it shows as /dev/ttyUSB0... i want to see the data coming out from it.. how can i do? i tried cat ttyUSB0 but nothing is shown
2015-02-13T14:22:32 < PaulFertser> Cyric_: use picocom or minicom or some other tool like that, disable flow control, configure proper baud rate etc.
2015-02-13T14:22:41 < akaWolf> lol
2015-02-13T14:22:53 < zyp> or just use stty to configure it first, then use cat
2015-02-13T14:22:54 < akaWolf> I have used minicom -- works fine
2015-02-13T14:23:21 < akaWolf> but I find putty for linux more usefull
2015-02-13T14:23:50 < Cyric_> the problem is that i do not have those stuff... i am in a 79mB buildroot/openwrt system

2015-02-13T14:25:01 < PaulFertser> Or GNU Screen
2015-02-13T14:25:19 < zyp> doesn't busybox have stty?
2015-02-13T14:25:29 < karlp> not in my owrt build no
2015-02-13T14:26:14 < karlp> you can enable it, but routers don't normally need it
2015-02-13T14:26:14 < zyp> are you sure it's not just the symlink that's missing?
2015-02-13T14:26:25 < karlp> BUSYBOX_CONFIG_STTY [=n] pretty sure :)
2015-02-13T14:26:30 < zyp> ah
2015-02-13T14:27:06 < karlp> most routers don't have exposed serial port, so just a waste of flash including stty
2015-02-13T14:27:25 < zyp> isn't unused flash wasted anyway? :)
2015-02-13T14:27:28 < karlp> I even _use_ the serial port, and i don't include stty in our own build
2015-02-13T14:27:51 < karlp> yeah, but you want to use that flash for things that _are_ useful, like moah javascript and manuals and images and shit, not stty
2015-02-13T14:28:13 < akaWolf> maybe some events
2015-02-13T14:28:14 < akaWolf> etc
2015-02-13T14:28:44 < Cyric_> well i have to add those packages and then recompile the image...

2015-02-13T14:29:55 < karlp> don't need the whole image to be rebuilt straight away
2015-02-13T14:30:15 < akaWolf> I guess, if it's not read-only system
2015-02-13T14:30:55 < karlp> read only with jffs2 overlay is normal openwrt style, ubifs for some newer devices with larger nand flashes
2015-02-13T14:31:38 < akaWolf> then scp will fail?
2015-02-13T14:31:51 < karlp> why?
2015-02-13T14:32:16 < akaWolf> becouse of read-only...
2015-02-13T14:32:18 < karlp> they have writable storage normally, but you shodul scp to /tmp into the ram filesystem.
2015-02-13T14:32:34 < akaWolf> ah ok
2015-02-13T14:32:34 < karlp> you build an image that's readonly, but it uses remaining flash as a writeable overlay,
2015-02-13T14:32:41 < karlp> plus a /tmp is a ramfs
2015-02-13T14:32:57 < akaWolf> well if you copy to /tmp then yes
2015-02-13T14:32:58 < karlp> of course it has writeable storage, that would be pretty useless without it :)
2015-02-13T14:33:09 < karlp> you can copy anywhere you like, it just uses up your overlay flash
2015-02-13T14:33:17 < akaWolf> mmm
2015-02-13T14:33:34 < karlp> what you scp over is just the package file, then you "opkg install picocom*.ipk"
2015-02-13T14:33:56 < karlp> I guess you could copy the binary over too, I was just suggesting a way of shortening his process to not rebuild the entire image and reflash it.
2015-02-13T14:34:26 < karlp> (nfs mounting your development environment is nice too...)
2015-02-13T14:36:34 < PaulFertser> BTW, OpenWrt now ships OpenOCD right there from the packages feed.

2015-02-14T01:09:47 < chickensk> hi, what does this mean? i just compiled normally and have errors since a while back make: *** No rule to make target 'main.elf', needed by 'main.hex'.  Stop.
2015-02-14T01:13:04 < qyx_> where did you get the makefile from?
2015-02-14T01:14:32 < chickensk> hi, stm32 examples from libopencm3, worked just fine until now
2015-02-14T01:14:41 < GargantuaSauce> it's telling you to stop, take its advice
2015-02-14T01:15:18 < chickensk> yes maybe i am going to sleep and continue tomorrow
2015-02-14T01:15:30 < GargantuaSauce> well did you change it?
2015-02-14T01:16:16 < chickensk> i added o files as the project is going
2015-02-14T01:16:26 < GargantuaSauce> sounds like the result of a parse error caused by a change on a preceding line
2015-02-14T01:16:47 < chickensk> when i remove certain o files it has different error

2015-02-14T01:17:21 < chickensk> hm shit
2015-02-14T01:17:45 < qyx_> chickensk: you have probably renamed your something.c to main.c
2015-02-14T01:17:52 < qyx_> and didn't read your makefile
2015-02-14T01:17:52 < zyp> how about you just pastebin the makefile so we can see?
2015-02-14T01:18:27 < qyx_> with default makefile you have to have your file named like project.c (project is the name you entered in te makefile)
2015-02-14T01:18:35 < qyx_> see your included makefiles from the liboipencm3 dir

2015-02-14T03:43:40 < emeb_mac> heh - parks-mclellan on the web
2015-02-14T03:43:46 < emeb_mac> we're in the future now
2015-02-14T03:44:08 < emeb_mac> nice
2015-02-14T03:44:15 < Laurenceb_> if it works...
2015-02-14T03:44:39 < emeb_mac> sometimes the pll will unlock when you switch bandwidths
2015-02-14T03:44:40 < Laurenceb_> or i could persuade silabs to send me the latest silicon revision
2015-02-14T03:44:53 < Laurenceb_> its turned off at end of preamble
2015-02-14T03:45:25 < ds2> what are you using the si446x for, Laurenceb_?
2015-02-14T03:45:33 < Laurenceb_> HAB uplink
2015-02-14T03:45:51 < ds2> what's HAB?

2015-02-14T03:46:04 < Laurenceb_> but I cant find rev C2 silicon
2015-02-14T03:48:06 < Laurenceb_> so im trying to farm it off to an stm32
2015-02-14T03:48:29 < ds2> what band is the chip running on?
2015-02-14T03:49:38 < Laurenceb_> 434mhz
2015-02-14T03:49:55 < ds2> wonder if the CC ones are less painful
2015-02-14T03:50:08 < Laurenceb_> i discovered i was having issues as WDS studio didnt support my silicon revision :P
2015-02-14T03:50:14 < Laurenceb_> yeah the config is horrific
2015-02-14T03:50:25 < Laurenceb_> and one bit wrong and you just get "invalid preamble"

2015-02-14T04:12:08 < GargantuaSauce> i was lazy and bought a couple TCM3105
2015-02-14T04:21:34 < dongs> that sounds ancient
2015-02-14T04:21:58 < dongs> As you know this part has not been manufactured in several years.
2015-02-14T04:21:58 < dongs> As a service to experimenters and hobbyists like myself these chips are available in single lots.
2015-02-14T04:22:01 < dongs> When you can find them this item is often sold in single lots at prices over twenty dollars.
2015-02-14T04:22:05 < dongs> Experimenter price for up to 5 pieces is $12.00 each plus $6.00 P&H inside the USA, $8.00 outside the USA.
2015-02-14T04:22:08 < dongs> TCM3105 chips are tested prior to shipping. All are 16 pin NL or JL package, my choice.
2015-02-14T04:22:12 < dongs> I can provide the 4.4336 MHz HC49/UR crystal for 1200 baud and the 6.5536 MHz crystal for 2400 baud.
2015-02-14T04:22:15 < dongs> lol
2015-02-14T04:22:54 < GargantuaSauce> got mine from some chinese ic hoarder on fleabay
2015-02-14T04:23:09 < GargantuaSauce> who has all sorts of weird old stuff
2015-02-14T04:23:15 < dongs> NL or JL = DIP right?
2015-02-14T04:23:31 < GargantuaSauce> haha you think there's a smd version of this?
2015-02-14T04:24:16 < ds2> sure
2015-02-14T04:24:27 < ds2> bend the legs out and you got a 0.1pitched SMD part ;)
2015-02-14T04:25:36 < GargantuaSauce> or inwards
2015-02-14T04:25:39 < GargantuaSauce> reduced footprint!
2015-02-14T04:26:11 < GargantuaSauce> for advanced miniaturization
2015-02-14T04:32:33 < dongs> that just gives you SOJ package
2015-02-14T04:32:50 < dongs> I once had to make SOJ out of msop8
2015-02-14T04:32:59 < dongs> because you know they have a bunmch of retarded different sized of thowse
2015-02-14T04:33:05 < dongs> some are a bit longer than otehrs
2015-02-14T04:33:12 < dongs> so I got ~500 boards made with a wrong fucking footprint
2015-02-14T04:33:24 < emeb_mac> I think I built a ham radio TNC with one of those years ago
2015-02-14T04:33:25 < dongs> had to carefully bend the legs in and place them
2015-02-14T04:33:47 < emeb_mac> but FSK is pretty fscking easy to do on an F373
2015-02-14T04:34:39 < emeb_mac> the hard part was frequency modulating it on / off of a 67kHz subcarrier
2015-02-14T04:35:04 < emeb_mac> that takes a lot more processor cycles because it needs to run @ 230ksps
2015-02-14T04:35:51 < dongs> use teh amazing DSP
2015-02-14T04:35:54 < dongs> unlike pic32
2015-02-14T04:36:04 < dongs> did you hear? Zano is ordering 500 boards with LM1117

2015-02-14T04:37:44 < _Sync_> well you can use a 1117, but it is shitty :D

2015-02-14T04:38:11 < dongs> HEH
2015-02-14T04:38:23 < dongs> so who did they buy them from

2015-02-14T04:52:31 < dongs> no
2015-02-14T04:52:35 < dongs> you can get both
2015-02-14T04:52:42 < dongs> 2 rows is centerline
2015-02-14T04:52:47 < dongs> so you can have thick flash chips on both sides

2015-02-14T05:05:37 < _Sync_> OBS?
2015-02-14T05:05:44 < GargantuaSauce> the concept that the encoder is shitty enough to allow that bugs me more than the actual visual artefacts
2015-02-14T05:06:18 < GargantuaSauce> 100% static scene with high frequency detail shouldnt be constantly changing and refreshing every keygrame

2015-02-14T11:40:46 < vvirag> a week ago I started with a STM32F407 discovery board, and I still try to setup a proper/convenient/efficient environment on Ubuntu 14.04. I downloaded the current release of gnu-arm-embedded toolchain, the STM32F4xx official firmware (from STM webpage), and tried to use Eclipse with the GNU-ARM-plugin. What really confusing about this situation, that Eclipse offers template for STM32F4, and states that the generated project files coming from the manu
2015-02-14T11:40:46 < vvirag> facturer (date 2014), but they are totally different than the official STM32F4xx firmware files (date 2011). What is the good practice for this?
2015-02-14T11:42:47 < zyp> hmm, I'm not really familiar with the st-provided stuff, I found it quite messy, so I've stayed away from it

2015-02-14T11:45:31 < zyp> yeah, that's old so that's probably stdperiphlib
2015-02-14T11:45:35 < vvirag> from here ^^, I use  STSW-STM32068
2015-02-14T11:45:41 < vvirag> oh, okay
2015-02-14T11:46:01 < zyp> http://www.st.com/web/catalog/tools/FM147/CL1794/SC961/SS1743/PF259242 <- and this would be the newer stuff, I guess
2015-02-14T11:46:10 < zyp> I haven't even looked at stm32cube myself
2015-02-14T11:47:46 < vvirag> uh, okay, thanks, I take a look
2015-02-14T11:47:57 < vvirag> however right now I feel even more confused :)
2015-02-14T11:48:18 < zyp> anyway, I suggest looking at libopencm3 too, before you settle for anything ;)
2015-02-14T11:55:28 < vvirag> it sill feels strange that it is so difficult to find out the best practice
2015-02-14T11:56:23 < vvirag> seems like everyone does it differently

2015-02-14T12:03:15 < zyp> everybody have different preferences, there's no one true solution
2015-02-14T12:07:57 < dongs> st isnt helping
2015-02-14T12:08:05 < dongs> by creating the shitheap that is stm32cube
2015-02-14T12:08:51 < vvirag> guys, thanks for all the suggestions, but I'm not there yet to make a decision :) actually I just wanted to try really simple stuff with my stm32f407.. but anytime if I look up for an example project (and try to figure out how would it be "nice"), I'm stuck because every setup is so different..
2015-02-14T12:16:32 < zyp> alternatives isn't a bad thing, you just have to figure out which to pick
2015-02-14T12:24:02 < vvirag> zyp, dongs trepidaciousMBR -- what are you using then?
2015-02-14T12:24:07 < vvirag> i try to make a statistic :)
2015-02-14T12:24:20 < zyp> neither, I wrote my own from scratch
2015-02-14T12:24:47 < zyp> but that was before I knew about libopencm3, otherwise I'd probably pick that
2015-02-14T12:25:25 < vvirag> zyp, you mean you wrote your own HAL lib?
2015-02-14T12:25:31 < zyp> yes
2015-02-14T12:25:39 < dongs> i dont think its "hal"
2015-02-14T12:25:44 < dongs> its more like osme named registers
2015-02-14T12:25:47 < dongs> and zero comments ;p
2015-02-14T12:26:43 < dongs> http://www.dhcameras.com/cf-card-1/ lul canon CF card repair parts ar e priced same way as the camera
2015-02-14T12:27:00 < dongs> cuz its same amount of crap anyway
2015-02-14T12:27:02 < dongs> why would one cost double
2015-02-14T12:27:54 < trepidaciousMBR> vvirag: ChibiOS - download the SVN, install ARM gcc, run make, done.
2015-02-14T12:28:40 < trepidaciousMBR> vvirag: There's a nice 407 disco example, then just look at the ChibiOS docs for anything else you want to do. You get a fairly complete HAL and (AFAICT) a really excellent realtime OS
2015-02-14T12:29:00 < dongs> but shitty syntax, many files, and requires gcc
2015-02-14T12:29:06 < dongs> all 3 pretty much showstoppers
2015-02-14T12:29:46 < qyx_> dongs, both chibios and freertos support many different compilers
2015-02-14T12:29:55 < trepidaciousMBR> vvirag: If you run into anything that's not supported, you can probably write your own code for it, either from datasheets for external stuff, or combination of ST datasheet and their code for MCU stuff. I agree with zyp that the ST code is pretty bad - mainly its useful for working out the stuff they don't tell you in the datasheet, but you still need to rewrite it ;)
2015-02-14T12:30:26 < trepidaciousMBR> dongs: Yup, ChibiOS has build stuff for other IDEs, although I thought they mostly just use GCC anyway, they just don't make a fuss about it ;)
2015-02-14T12:31:05 < zyp> libopencm3 also have examples for stm32-disco and is as easy to get going, and less complex overall
2015-02-14T12:31:22 < trepidaciousMBR> dongs: On the files front, it's just fairly organised, probably you will end up with a bigger bin file than if you started from scratch yourself, but flash sizes are pretty big anyway
2015-02-14T12:32:09 < zyp> and recommending an rtos when somebody simply wants a hardware library is kinda overkill :)
2015-02-14T12:32:15 < vvirag> trepidaciousMBR, are you involved in ChibiOS?
2015-02-14T12:32:49 < trepidaciousMBR> vvirag: Not really, I've contributed to it a little, mainly just finding and helping out with some bugs, and support for 42X/43X
2015-02-14T12:32:55 < trepidaciousMBR> vvirag: Mainly I just use it
2015-02-14T12:34:05 < trepidaciousMBR> zyp: I'm not sure, if you don't want to use lots of threads etc. you don't need to, you can still just do everything in the main thread and ignore the fact that it's an RTOS if you want, but then if you want to do something more complex it's there already. Plus the HAL is pretty good, seems a shame not to use it just because you don't currently want an RTOS
2015-02-14T12:35:02 < zyp> it weren't «pretty good» when I looked at it around four years ago :)
2015-02-14T12:35:19 < trepidaciousMBR> zyp: Ah ok, what problems did you have with it?
2015-02-14T12:36:29 < qyx_> it's good for blinky leds and simple stuff
2015-02-14T12:36:43 < qyx_> you will be pulling your hair when trying to reconfigure clocks at runtime
2015-02-14T12:36:44 < zyp> and judging by people recently talking about running the chibios core with libopencm3 for hardware leads me to believe that the HAL is still not much better :)
2015-02-14T12:37:25 < trepidaciousMBR> zyp: Fair enough, I've not really had any problems with it myself, there was some odd stuff with UARTs but that got resolved, that's about it
2015-02-14T12:37:39 < zyp> trepidaciousMBR, well, the i2c driver was completely unusable, for once, but I expect that to be long solved now
2015-02-14T12:37:55 < trepidaciousMBR> qyx_: My application might be slightly unusual, I don't really need to change clocks after startup
2015-02-14T12:38:08 < trepidaciousMBR> zyp: Ah ok, I've used it a bit and it seems fine, again I might just be lucky
2015-02-14T12:38:24 < zyp> it was more a problem that I felt that the API worked against me in any way
2015-02-14T12:38:38 < zyp> which is what prompted me to start on my own lib from scratch
2015-02-14T12:38:39 < qyx_> that too
2015-02-14T12:38:50 < qyx_> i moved to libopencm3 too
2015-02-14T12:39:35 < vvirag> okay, maybe you could suggest me something with more information about my use case: i would like to generate some sine signals, and do phase modulation.. Based on what you've said already, maybe libopencm3 seems more convenient
2015-02-14T12:39:39 < trepidaciousMBR> I guess there's no reason at all you can't use the rtos bits of ChibiOS and something else for hardware access
2015-02-14T12:40:08 < zyp> trepidaciousMBR, like I said, people already do that
2015-02-14T12:40:12 < trepidaciousMBR> There;s not really any support for FMC or DCMI, so I just do that myself for example
2015-02-14T12:40:45 < trepidaciousMBR> zyp: Yup I was just saying it kind of makes sense, if there is some peripheral where cm3 seems more reliable

2015-02-14T15:40:34 < qyx_> huh
2015-02-14T15:41:05 < qyx_> why are people using like 10 discrete analol and 74xx chips when theres MCU available
2015-02-14T15:42:25 < BrainDamage> because they are used to the arduino having the computational capability of a rock
2015-02-14T15:43:08 < qyx_> envelope detector, zero crossing detector
2015-02-14T15:43:17 < qyx_> i would assume that dsp is quite common in 2014
2015-02-14T15:44:23 < qyx_> and building amplifiers from discrete darlington npns
2015-02-14T15:49:38 < karlp> aren't you meant to build darlingonts from discretes yourself? isn't it cheating to buy a darlington prepackaged?
2015-02-14T15:53:58 < qyx_> i still don't get why they are measuring in both directions
2015-02-14T15:54:24 < jpa-> to compensate the constant delay automatically?
2015-02-14T15:55:02 < qyx_> maybe
2015-02-14T15:55:42 < qyx_> but theres another approach using doppler effect and not time-of-flight
2015-02-14T15:57:20 < Steffanx> doppler doesnt work
2015-02-14T15:58:06 < qyx_> why shouldn't it?
2015-02-14T15:59:49 < Steffanx> because the transmitter and receiver are moving at the same speed.

2015-02-14T16:03:07 < Steffanx> much more interesting than the arduino one
2015-02-14T16:05:27 < Devilholk> I am thinking about writing my own boot code for a project, and I would like them as separate projects. I am looking into how the interrupt vector table is implemented and it is a vector table in beginning of ROM. So if I use interrupts in my boot loader I need to have a custom handler in the interrupt that either does the boot ISR or jumps inside the application ISR?
2015-02-14T16:05:44 < Devilholk> Or can I some how move the vector table?
2015-02-14T16:06:39 < karlp> m3 and m0+ have scb->vtor
2015-02-14T16:06:45 < karlp> m0 is shit out of luck...
2015-02-14T16:06:50 < Devilholk> I'm using m3 and m4
2015-02-14T16:07:07 < karlp> https://github.com/karlp/zypsnips/blob/master/jump-to-app-from-bootloader.c
2015-02-14T16:07:33 < karlp> plus of course all the linker script mechanics to put your vector tables in the right place.
2015-02-14T16:08:07 < Devilholk> I wonder if I have a SCB struct..
2015-02-14T16:08:19 < Devilholk> That jump changes the stack pointer?
2015-02-14T16:08:49 < karlp> you probably don't have _that_ SCB struct, thta's from zyp's laks project.
2015-02-14T16:08:54 < Laurenceb_> attn BrainDamage (NSFW) :  http://imageserve.babycenter.com/15/000/286/2O4vDLheDO5hdbvc31uOir1Bc1Vls1Oj_lg.jpg
2015-02-14T16:08:55 < karlp> but the intention is the same.
2015-02-14T16:09:14 < Devilholk> What is the point of that struct?
2015-02-14T16:09:52 < karlp> it's the System Control Block of the core... the VTOR is a register in that block.
2015-02-14T16:09:54 < qyx_> Steffanx: mhm, interesting
2015-02-14T16:10:43 < Steffanx> I actually built something like that, but i partially failed because my dsp sucked.
2015-02-14T16:11:00 < Devilholk> karlp: Cool, I found some info in a header file dealing with SCB
2015-02-14T16:11:13 < Steffanx> and the analogs sucked.
2015-02-14T16:12:36 < Devilholk> karlp: So first one updates VTOR in SCB, then one loads SP to offset, then something weird happens and then you branch to offset
2015-02-14T16:14:23 < Devilholk> I think I get it after reading up on the LDR instruction
2015-02-14T16:14:35 < karlp> taking the pc from the second entry in the new vector table iirc
2015-02-14T16:14:51 < Devilholk> The new reset vector probably
2015-02-14T16:16:26 < Devilholk> karlp: Are you the same guy who have written some (or perhaps all) of the linker scripts of libopencm3?
2015-02-14T16:16:34 < Steffanx> I could've fixed it by averaging more and also filtering outliers. Should try to get my anemometer setup back and redo the software/hw

2015-02-14T18:29:43 < dongs> eh
2015-02-14T18:29:46 < dongs> thats how bootloaders usually work
2015-02-14T18:29:56 < dongs> now for bonus points, make a bootloader updater bootloder.
2015-02-14T18:32:04 < Laurenceb_> dawg
2015-02-14T18:32:31 < Laurenceb_> someone needs to make a µSD card bootloader
2015-02-14T18:32:32 < specing> so elite
2015-02-14T18:32:34 < Laurenceb_> thats no huge
2015-02-14T18:32:40 < Laurenceb_> *not
2015-02-14T18:34:29 < Laurenceb_> actually that could brick itself
2015-02-14T18:34:44 < Laurenceb_> unless it also included usb mass stoRAGE
2015-02-14T18:34:52 < Laurenceb_> actually didnt leaflabs make this?
2015-02-14T18:38:46 < zyp> dongs, I've done that
2015-02-14T18:39:03 < dongs> but itwas in c++ and python
2015-02-14T18:39:23 < zyp> no python
2015-02-14T18:40:30 < zyp> I made a separate binary containing a new bootloader binary
2015-02-14T18:40:38 < zyp> I called it a bootloaderloader
2015-02-14T18:41:55 < zyp> the bootloaderloader was uploaded as a normal binary through the usual bootloader, and when executed it first verified itself, then it erased and overwrote the existing bootloader, and if everything went ok, it killed itself to avoid running again and reset the chip

2015-02-14T18:43:15 < zyp> the goal of that process was to alleviate the risk of bricking, which would happen if the process was interrupted between the erase of the old bootloader and the finish of writing the new bootloader

2015-02-14T18:43:30 < emeb_mac> so then you're left with a device that has nothing on it but the bootloader?
2015-02-14T18:43:37 < zyp> correct
2015-02-14T18:43:49 < zyp> and then you flash a normal firmware through the new bootloader
2015-02-14T18:45:13 < zyp> the bootloader checks for a valid flash addr in the application vector table, and if it can't find one it goes into bootloader mode instead
2015-02-14T18:45:28 < zyp> so the bootloaderloader killed itself by erasing the first sector containing the vector table
2015-02-14T18:46:40 < emeb_mac> simpler than loading a flash erase stub into RAM I guess
2015-02-14T18:47:46 < zyp> it only started erasing the old bootloader after completing self verification, and then it did the write without depending on any sort of user input, so the only way a user could botch it would be to pull the power in the small window between start of erase and writing finished
2015-02-14T18:47:54 < dongs> https://www.reddit.com/r/japanlife/comments/2vn6o4/why_are_there_no_police_in_the_police_station/ lol
2015-02-14T18:48:05 < zyp> and that window is only a couple of milliseconds, I believe
2015-02-14T18:48:26 < zyp> erasing/writing <8k doesn't take long when the data is already available on chip
2015-02-14T18:50:24 < emeb_mac> ya
2015-02-14T18:51:03 < zyp> it worked out well, got no user complaints about bricked boards
2015-02-14T18:51:33 < zyp> dongs, heh
2015-02-14T18:52:38 < PaulFertser> With dual bank stm32ls you have ROM bootloader that verifies sanity of stack pointer or reset vector, and if they're not sane try the second bank.

2015-02-14T19:02:35 < Devilholk> Does stuff in the .bss section get zeroed when doing a system reset? Or is this device specific?
2015-02-14T19:02:45 < dongs> why would it
2015-02-14T19:02:52 < dongs> ram doesnt get erased
2015-02-14T19:02:55 < dongs> on any stm32 as fasr a I know
2015-02-14T19:02:59 < Devilholk> I suspected as much
2015-02-14T19:03:03 < dongs> i've abused that before.
2015-02-14T19:04:19 < zyp> .bss get zeroed by the startup code, not by hardware
2015-02-14T19:04:27 < dongs> that
2015-02-14T19:04:45 < zyp> and yes, .bss get zeroed by spec, so that's guaranteed
2015-02-14T19:04:46 < kakeman> haven't done any work in days
2015-02-14T19:04:48 < kakeman> shieet
2015-02-14T19:04:51 < zyp> provided your startup code is sane
2015-02-14T19:05:36 < Devilholk> I declare vars like this http://paste.debian.net/148193/ with this linker script http://paste.debian.net/148192/ (includes https://github.com/libopencm3/libopencm3/blob/master/lib/stm32/f1/libopencm3_stm32f1.ld )
2015-02-14T19:05:46 < Devilholk> But the start code do appear to clear .bss
2015-02-14T19:05:57 < Devilholk> And it seems that my boot_vars are placed in bss
2015-02-14T19:07:02 < zyp> BOOT_VARS vs .BOOT_VARS
2015-02-14T19:07:23 < Devilholk> Should I lose the dot?
2015-02-14T19:07:32 < Devilholk> I am noob with linker scripts
2015-02-14T19:07:43 < zyp> either remove it from the linker script or add it to the c file
2015-02-14T19:08:22 < zyp> you're putting the struct into a new section called BOOT_VARS, but then the linker script rule looks for sections called .BOOT_VARS

2015-02-14T19:10:13 < zyp> and since the linker script says nothing about what to do with the input section caled BOOT_VARS, it's putting it into .bss since that's what it would otherwise do if you didn't specify a sectio
2015-02-14T19:12:22 < Devilholk> Trying with losing the dot then (I think I understand but need to test it to be sure)

2015-02-14T19:28:55 < GargantuaSauce> ...yes
2015-02-14T19:29:08 < kakeman> like putting chars out of uart
2015-02-14T19:31:34 < kakeman> I don't quite see the point there

2015-02-14T19:37:18 < kakeman> swo can actually use uart type encoding /o\
2015-02-14T19:37:36 < kakeman> or manchester encoding
2015-02-14T19:37:42 < kakeman> it's just another uart
2015-02-14T19:37:46 < kakeman> one direction
2015-02-14T19:39:45 < PaulFertser> kakeman: it's fast, and you can get some events automatically out of it, and you can have timestamping of events. And if you have a suitable device to capture, you can have it even faster than UART etc. You can also get ETM trace data via it.
2015-02-14T19:40:56 < PaulFertser> kakeman: also, it provides multiplexing for many channels, and it can be configured by debugger, you can have all ITM access in production firmware, it doesn't affect much.
2015-02-14T19:41:29 < PaulFertser> ITM + DWT + ETM + TPIU is way, way cooler than just another uart.

2015-02-14T21:10:35 < Getty> but there is for sure the case for xDSL technology, whatever one
2015-02-14T21:10:44 < kakeman> if you have 5km distance
2015-02-14T21:10:55 < kakeman> you don't put your stm32 gpio pin to wire
2015-02-14T21:11:08 < Getty> yeah but you dont have that case in germany, regulary........
2015-02-14T21:11:35 < Getty> there is no 5km long copper wire...... ;)

2015-02-14T22:39:51 < kakeman> so what I coul in example do with my simple swo viewer is sending messages when entering and exiting functions to measure time used in function?
2015-02-14T22:40:42 < kakeman> is there some tools toolkits for this?
2015-02-14T22:40:52 < kakeman> apart from keil
2015-02-14T22:41:22 < PaulFertser> kakeman: you can intrument your function manually in no time, and then just look at trace output.
2015-02-14T22:41:46 < kakeman> yeah so manual job
2015-02-14T22:41:59 < kakeman> it will most cases do
2015-02-14T22:42:39 < PaulFertser> kakeman: I'm studying this stuff atm, you can also use DWT to pass events to ETM, so that can work without code changes. But you do not have too many DWT comparators usually.
2015-02-14T22:43:56 < kakeman> events like entering function?
2015-02-14T22:44:27 < PaulFertser> Yes, if you set DWT to trigger on that address.
2015-02-14T22:45:10 < kakeman> so you could have like 3functions to look at the time
2015-02-14T22:45:36 < PaulFertser> If you have 6 comparators ("watchpoint units"), yes.
2015-02-14T22:45:52 < kakeman> so if there is 4 then
2015-02-14T22:45:55 < PaulFertser> Or you can instrument them beforehand and have any number you want.
2015-02-14T22:46:43 < karlp> there's also a few preset events, so you can get timing for all exception enter/exit for instance.
2015-02-14T22:46:53 < kakeman> nice
2015-02-14T22:46:53 < PaulFertser> Yes
2015-02-14T22:47:16 < karlp> it's a hugely underappreciated feature, but paul's fixing all that for us ;)
2015-02-14T22:47:26 < kakeman> hmm
2015-02-14T22:47:34 < PaulFertser> kakeman: any other preset events?
2015-02-14T22:48:34 < karlp> kakeman: it's got all sorts of combinations, get into the arm coresight docs
2015-02-14T22:49:04 < PaulFertser> karlp: I'm not planning on fixing all of that, unfortunately. I guess I'll try adding the ITM and most useful DWT bits that I've omitted for now, but that would probably be about it.
2015-02-14T22:50:09 < karlp> simple manual tracing is something like "uint32_t before = SCS_DWT_CYCCNT; <do stuff> ITM32[channelnum] = SCS_DWT_CYCCNT - before;"
2015-02-14T22:50:22 < PaulFertser> And that "most useful" I'd rather hear from you guys instead of counting on my own judgement.
2015-02-14T22:50:23 < karlp> PaulFertser: yeah, that's still heaps an dheaps more than we had before
2015-02-14T22:50:46 < karlp> sorry, simple manual _timing_ is like that.
2015-02-14T22:52:59 < kakeman> so what is PaulFertser developing?
2015-02-14T22:53:15 < karlp> he's improving the tracing support in openocd
2015-02-14T22:53:31 < karlp> https://pastee.org/pw9qh uses a few different itm ports, but the timing is in another function...

2015-02-14T23:04:27 < kakeman> oh part of it is for trace port
2015-02-14T23:07:50 < kakeman> let's climb
2015-02-14T23:14:02 < PaulFertser> karlp: I've just took a look at the ETM code that already exists in OpenOCD. Not much to reuse.
2015-02-14T23:16:11 < PaulFertser> Or probably enough for a start.
2015-02-14T23:17:39 < karlp> never looked at it to be honest, just saw it in the openocd docs while looking for somethign else

2015-02-15T00:12:59 < qyx_> why don't people watch their consts
2015-02-15T00:16:59 < upgrdman> speaking of consts, is there a gcc fag to warn you when a varialble could be const (e.g. is never written to after init) ?
2015-02-15T00:17:03 < upgrdman> err flag
2015-02-15T00:22:50 < emeb_mac> damn bro - you should know that.
2015-02-15T00:23:06 < emeb_mac> not wait around for the compiler to tell you. :)
2015-02-15T00:23:53 < upgrdman> ya, but it would be nice to be warned
2015-02-15T00:24:18 < upgrdman> sometimes you're too busy innovating to plan things out ;)
2015-02-15T00:32:59 < Laurenceb_> wtf http://i.imgur.com/bHMgaM9.jpg
2015-02-15T00:33:24 < karlp> tl;dr
2015-02-15T00:33:56 < Laurenceb_> yo emeb_mac: you any good with FIR filter design using fixed point
2015-02-15T00:34:43 < Laurenceb_> https://raw.githubusercontent.com/Laurenceb/STM32_Launcher/master/Silabs/Config_dev/Silabs_Custom_860hz_Highgain.png
2015-02-15T00:34:49 < emeb_mac> Laurenceb_: do it all the time
2015-02-15T00:34:55 < Laurenceb_> i have a problem with si446x config - it uses 10bit fixed point
2015-02-15T00:35:28 < emeb_mac> OK - shouldn't be a big deal
2015-02-15T00:35:29 < Laurenceb_> im trying to make quite a wide filter, looks like the si446x expects 64-65dB filter gain
2015-02-15T00:35:37 < Laurenceb_> thats the best i could do
2015-02-15T00:35:57 < Laurenceb_> is there some trick im missing?
2015-02-15T00:36:49 < emeb_mac> that's either a nasty sidelobe or a nasty suckout
2015-02-15T00:37:01 < emeb_mac> what filter design algo you using?
2015-02-15T00:37:12 < Laurenceb_> that T-filter page
2015-02-15T00:37:22 < emeb_mac> Got Matlab?
2015-02-15T00:37:40 < Laurenceb_> yes
2015-02-15T00:37:41 < Laurenceb_> newfilt=[-12,-23,17,58,-19,-112,7,178,31,-243,-122,291,503,511,503,291,-122,-243,31,178,7,-112,-19,58,17,-23,-12,];
2015-02-15T00:38:09 < emeb_mac> signal toolbox firpm() is what I usually use for FIRs
2015-02-15T00:38:14 < Laurenceb_> ok
2015-02-15T00:38:36 < emeb_mac> you know how many taps max the si part allows
2015-02-15T00:38:40 < Laurenceb_> 28
2015-02-15T00:39:05 < emeb_mac> so plug that in for the order (minus 1, so 27 order) and then put in your F and A vectors
2015-02-15T00:39:42 < emeb_mac> then multiply by 511 to scale up to 10bit signed
2015-02-15T00:39:50 < emeb_mac> and take a floor / integer.
2015-02-15T00:39:55 < emeb_mac> that's where I'd start
2015-02-15T00:40:28 < emeb_mac> play with the start / stop transition in your F vector to get the filter shape you need and the stopband rejection you can get away with.
2015-02-15T00:40:51 < Laurenceb_> ok
2015-02-15T00:41:00 < emeb_mac> use the freqz() function to plot out the response
2015-02-15T00:41:21 < emeb_mac> you can probably script the whole thing up in a dozen lines of code or so
2015-02-15T00:41:33 < emeb_mac> then just iterate until you get something that looks nice

2015-02-15T00:42:59 < Laurenceb_> ok
2015-02-15T00:43:50 < emeb_mac> if you've got a license for filter toolbox then a lot of this can be done in FDAtool
2015-02-15T00:44:01 < emeb_mac> all interactively
2015-02-15T00:44:14 < Laurenceb_> ok
2015-02-15T00:44:22 < Laurenceb_> ill see what i can do on my work pc :P
2015-02-15T00:44:49 < emeb_mac> if you've got octave installed on a handy machine then that works too.
2015-02-15T00:44:59 < emeb_mac> just use remez() instead of firpm()
2015-02-15T00:45:04 < emeb_mac> same thing, different name
2015-02-15T00:45:52 < Laurenceb_> ah
2015-02-15T00:46:26 < Laurenceb_> yeah this is the same as t-filter
2015-02-15T00:46:33 < Laurenceb_> ill stick with t-filter as it has a gui
2015-02-15T00:46:45 < Laurenceb_> unless theres something im missing?
2015-02-15T00:46:59 < emeb_mac> does t-filter let you do the quantization?
2015-02-15T00:47:03 < Laurenceb_> i guess i could do a state space search across the filter bands
2015-02-15T00:47:05 < Laurenceb_> yes
2015-02-15T00:47:15 < emeb_mac> aha - then it's about the same
2015-02-15T00:47:18 < Laurenceb_> so i can set gain and check the range
2015-02-15T00:47:22 < Laurenceb_> ok
2015-02-15T00:47:32 < emeb_mac> I have wrapped the whole thing up in an optimizer before
2015-02-15T00:47:37 < Laurenceb_> yeah
2015-02-15T00:47:40 < Laurenceb_> sounds useful
2015-02-15T00:47:46 < Laurenceb_> im trying to optimise by hand
2015-02-15T00:47:46 < emeb_mac> simulated annealing with random variations on the coefficients
2015-02-15T00:47:54 < Laurenceb_> theres only a few things i care about
2015-02-15T00:47:57 < Laurenceb_> yeah
2015-02-15T00:48:12 < Laurenceb_> need a D-wave :P
2015-02-15T00:48:15 < emeb_mac> using the pass-band ripple and stop-band rejection as the cirteria
2015-02-15T00:48:51 < emeb_mac> but without that the only knob you really have is the transition band width
2015-02-15T00:49:00 < emeb_mac> that's the one I mainly play with
2015-02-15T00:49:13 < Laurenceb_> ok
2015-02-15T00:49:29 < emeb_mac> wider transition band means better ripple & rejection
2015-02-15T00:49:30 < Laurenceb_> my problem is that i cant get the gain without exceeding the +-511 range
2015-02-15T00:49:57 < emeb_mac> you shouldn't be trying to get gain from the filter
2015-02-15T00:50:11 < emeb_mac> just filter - let the rest of the system AGC or whatever
2015-02-15T00:51:07 < emeb_mac> since coefficients are limited to 10-bits signed you have no freedom for gain.
2015-02-15T00:51:38 < emeb_mac> just normalize everything so the max coeff is 511
2015-02-15T00:52:59 < Laurenceb_> hmm
2015-02-15T00:53:09 < Laurenceb_> ok i guess i could try
2015-02-15T00:53:28 < Laurenceb_> all the WDS filters have gain between 64 and 65dB, i suspect its not a coincidence
2015-02-15T00:54:11 < emeb_mac> well, with 10-bit coeffs that's about the neighborhood you'll usually be in.
2015-02-15T00:54:24 < emeb_mac> I wouldn't sweat a few dB more or less
2015-02-15T00:54:36 < Laurenceb_> ok
2015-02-15T00:54:54 < Laurenceb_> ill have to try it on the hardware and see what happens
2015-02-15T00:55:19 < Getty> yeah sure.... i can wait forever till that unsigned value gets -1.... i get that....
2015-02-15T00:55:35 < Laurenceb_> huh?
2015-02-15T00:55:42 < Getty> not related ;)
2015-02-15T00:59:08 < Laurenceb_> i should probably have tried a PSK uplink
2015-02-15T00:59:30 < Laurenceb_> there may well be enough info from the silabs PLL tracker to do it
2015-02-15T01:00:26 < Laurenceb_> atm I have tone sep == bps
2015-02-15T01:00:44 < Laurenceb_> so phase is coherent at each of the tone frequencies
2015-02-15T01:01:25 < Laurenceb_> then in Rx "listen" mode, it runs the larger bandwidth filter im trying to design, together with a PLL that tries to lock onto a carrier
2015-02-15T01:02:07 < Laurenceb_> if it gets a modulated carrier it waits until PLL has converged then switches to the tight IF filter and runs the packet engine
2015-02-15T01:02:49 < Laurenceb_> if packet Rx fails it resets the PLL to the last frequency
2015-02-15T01:02:55 < Laurenceb_> thats the idea anyway....
2015-02-15T01:04:03 < Laurenceb_> this way it can tolerate +-1.5ppm TCXO drift with sensitivity thats about 8dB better than datasheet spec
2015-02-15T01:04:45 < qyx_> Getty: you are ignoring the warnings

2015-02-15T03:42:59 < kakeman> should one be concerned of constant ssh connections trying to login to my server
2015-02-15T03:43:01 < kakeman> ?
2015-02-15T03:43:15 < kakeman> should I be
2015-02-15T03:43:46 < kakeman> one comes in tries to login, leaves, another comes in
2015-02-15T03:44:22 < karlp> get used to it.
2015-02-15T03:45:23 < kakeman> so it's basically just constant knockin to door but no-one enters
2015-02-15T03:52:17 < specing> kakeman: look into magic packet authorization
2015-02-15T03:53:16 < Getty> knock knock knocking on the s s h.....
2015-02-15T03:53:55 < BrainDamage> use public key auth to drastically reduce the brute force possibility and set to a non standard port to reduce the noise in the logs, that's pretty much it
2015-02-15T03:54:07 < Getty> the port is the most relevant
2015-02-15T03:54:14 < BrainDamage> no, the key is
2015-02-15T03:54:28 < BrainDamage> the key gives security, the port only reduce the noise in the logs
2015-02-15T03:54:58 < Getty> yeah both parts are relevant. If you change the port, you are often missed out when there is a ssh security flaw
2015-02-15T03:55:36 < Getty> both is just crucial ;) if you wanna call yourself "safe"
2015-02-15T03:55:48 < Getty> and even then.............. AND EVEN THEN!
2015-02-15T03:56:08 < Getty> port knocking with the other 2 is actually making it REALLY brutal secure
2015-02-15T03:56:20 < BrainDamage> they aren't really giving security
2015-02-15T03:56:30 < Getty> security is cutting cable ;)
2015-02-15T03:56:31 < BrainDamage> they are in fact, obscurity
2015-02-15T03:56:52 < BrainDamage> anyone seeing your traffic would see the correct port and the knocking sequence
2015-02-15T03:57:10 < BrainDamage> they only make flyby attacks less practical
2015-02-15T03:57:11 < Getty> nothing is safe
2015-02-15T03:57:27 < Getty> IF someone WANTS to hit you, then you nothing makes it safer really
2015-02-15T03:57:51 < BrainDamage> sure, but distinguishing actual designed security boundaries vs some obfuscation is fundamental
2015-02-15T03:58:03 < kakeman> creating your own obscure protocol is the best
2015-02-15T03:58:05 < Getty> but port knocking, port change + key only, is at least safe for all known scanning based attacks, even tho it doesnt EXCLUDE the case, i just wouldnt recall that some automatic was that intelligent
2015-02-15T03:58:55 < BrainDamage> if you want to do active trolling to port scanners, there's some services that do the opposite
2015-02-15T03:59:08 < BrainDamage> instead of being silent, they report as if every port has a service
2015-02-15T03:59:15 < Getty> yeah, honeypotting ;)

2015-02-15T03:59:17 < Getty> thats fun
2015-02-15T03:59:29 < BrainDamage> it's slightly different here
2015-02-15T03:59:31 < Getty> i love the fake ssh idea like really fully with fake shell and everything, just to fuck with people
2015-02-15T03:59:36 < BrainDamage> it's not an actual service running
2015-02-15T03:59:43 < BrainDamage> just listening to the port
2015-02-15T03:59:52 < BrainDamage> and giving correct initializer
2015-02-15T03:59:52 < kakeman> hmm
2015-02-15T03:59:53 < Getty> yeah ok, thats also an option to confuse them
2015-02-15T03:59:58 < kakeman> fake door
2015-02-15T04:00:09 < kakeman> is actually just wall of concrete
2015-02-15T04:00:09 < BrainDamage> again, all of this is obscurity, not security
2015-02-15T04:00:12 < BrainDamage> altough kinda fun
2015-02-15T04:00:16 < Getty> the fake ssh i saw once actually just accepted all passwords, if you tried with password
2015-02-15T04:00:34 < Getty> it always worked, and logged all the activity the other thing did, and answered back with totally fake data for most common commands
2015-02-15T04:00:43 < kakeman> hmm
2015-02-15T04:01:24 < Getty> if you could make a star trek style worm that destroys the hive of the scanners if they encounter them.............. ;)
2015-02-15T04:01:32 < GargantuaSauce> i use a nonstandard port for ssh and it makes for near-zero driveby attempts
2015-02-15T04:01:41 < GargantuaSauce> not more secure but at least there's less garbage in the logs
2015-02-15T04:01:59 < BrainDamage> that's what i repeated multiple times it's for
2015-02-15T04:02:02 < BrainDamage> less shit in logs
2015-02-15T04:02:05 < BrainDamage> no more, no less
2015-02-15T04:02:44 < GargantuaSauce> yeah well i didn't read more than 2 lines of backlog so there
2015-02-15T04:03:18 < BrainDamage> it's getty that claims that things like port knocking etc are security
2015-02-15T04:03:32 < BrainDamage> not that they aren't useful, they just don't provide real security
2015-02-15T04:04:58 < BrainDamage> ( security is when the attacker knows every part of your system except the secrets and still cannot get access to the data ), in your case the paradigm can be easily violated by simple traffic analysis
2015-02-15T04:06:14 < kakeman> can you learn something nowdays if you let attacker to play around in some sort of sandbox?
2015-02-15T04:06:15 < Getty> they add up security, they dont make it perfect, i mean its always a point of view, as i see: there is no perfect security, if someone wanna come in and invest enough, he will find some way, and if its indirect (like with real world attacks to get your stuff, like ssh keys from the machine)
2015-02-15T04:06:29 < Getty> some messures add a lot, some messures are pretty useless
2015-02-15T04:06:29 < kakeman> and log actions
2015-02-15T04:07:36 < BrainDamage> there's a definition of security, you can make up your own,but communication is estabilished on common basis so trying to talk without estabilishing one leads to plenty of frustration, so define your concept of security?
2015-02-15T04:08:09 < Getty> well what you call security? so all that what we said here is not adding up security? just because its obscurity means its not having any security value? ;)
2015-02-15T04:08:30 < BrainDamage> (03:03:32) BrainDamage: not that they aren't useful, they just don't provide real security
2015-02-15T04:08:52 < Getty> "real security"... ok so everytime you say "real security" you mean those kind of security messures which are real security and not just obscurity?
2015-02-15T04:09:07 < BrainDamage> i mean things that fit the paradigm said above ^^^
2015-02-15T04:09:07 < Getty> like keyonly login and.... what else?
2015-02-15T04:09:15 < GargantuaSauce> fucking kerckhoff's principle, this is not a new concept dude
2015-02-15T04:10:07 < Getty> well i think i never said its "real security" so i still miss out my fault, if you say its the term "real security"
2015-02-15T04:10:16 < Getty> do we really discuss here about the wording for "security"?
2015-02-15T04:10:52 < BrainDamage> i'm discussing the fact you say it helps security, when it doesn't according to the common definition since > 100 years
2015-02-15T04:11:11 < Getty> oh so you say the sentence "Its more secure with changed port then it is with standard port" is wrong?
2015-02-15T04:11:24 < Getty> isnt that a bit picky?
2015-02-15T04:11:39 < BrainDamage> well, it gives some sort of illusion of protection
2015-02-15T04:11:46 < Getty> well is the sentence wrong or right? thats the question
2015-02-15T04:12:05 < BrainDamage> it's wrong according to the definition, if you have your own, i asked to provide so
2015-02-15T04:12:18 < BrainDamage> so we could have a common basis of dialogue
2015-02-15T04:12:28 < Getty> oookkkkk... no idea, the definition of "security" is not really vague in my eyes, wait let us check
2015-02-15T04:12:42 < Getty> the state of being free from danger or threat. // a private police force that guards a building, campus, park, etc.
2015-02-15T04:13:14 < BrainDamage> in the field of mathematics / CS / cryptography which were're actually talking about, it has a very specific definition
2015-02-15T04:13:34 < BrainDamage> that's why i picked that
2015-02-15T04:13:47 < Getty> lol ok ;) i just talked like a human and use the word secure in the common sense
2015-02-15T04:14:03 < Getty> but if you want to go science, then yeah ok, nothing is secure, ever, you cant reach security, alone mentioning the word is braindead then ;)

2015-02-15T05:31:34 < GargantuaSauce> must have just two motors and a really weird differential crank system or something

2015-02-15T05:35:18 < dongs> you'd need insane refresh rate for that to even try working, not to mention you wouldnt see it like that anyway
2015-02-15T05:35:34 < GargantuaSauce> just look at the linear axis
2015-02-15T05:36:07 < GargantuaSauce> the acceleration to oscillate like that would be insane
2015-02-15T05:36:11 < dongs> right
2015-02-15T05:36:29 < dongs> maeybe its maglev!!
2015-02-15T05:36:44 < dongs> and its a mini railgun
2015-02-15T05:36:54 < dongs> amazejaptech
2015-02-15T05:37:10 < dongs> shoots it one way, and theres a spring to bounce it back
2015-02-15T05:37:19 < dongs> with zero friction, so doable
2015-02-15T05:37:25 < GargantuaSauce> i cba to calculate the force but i feel like it would probably tear the phone in half
2015-02-15T05:37:27 < GargantuaSauce> that'd be cool
2015-02-15T05:38:48 < dongs> oops i forgot they'd need to have the setup in a vacuum for that to work
2015-02-15T05:39:43 < GargantuaSauce> and it would induce huge currents in every trace on the pcb
2015-02-15T05:40:01 < dongs> of the phone?
2015-02-15T05:40:09 < GargantuaSauce> ya
2015-02-15T05:40:21 < dongs> from railgun?
2015-02-15T05:40:26 < dongs> or just from motion
2015-02-15T05:41:28 < GargantuaSauce> the linear motor/railgun/whatever

2015-02-15T05:42:49 < GargantuaSauce> pretty clear confirmation that it's just two dc motors

2015-02-15T08:16:37 < upgrdman> tempted to dick with BGAs. seeed and dirtypcbs want big ass vias... (12+ mil holes, etc.) what's the cheapest pcb fab'er that will do smallish vias?
2015-02-15T08:16:39 < dongs> takes effort to stick that shit in
2015-02-15T08:16:51 < dongs> upgrdman: i can do 0.3/0.5 standard
2015-02-15T08:16:57 < dongs> you can do down to 0.85mm pitch with that
2015-02-15T08:17:10 < upgrdman> yes, but youre fab house isnt cheap, right?

2015-02-15T08:18:58 < upgrdman> oshpark: "The minimum specs for 4 layer orders are 5 mil traces with 5 mil spacing, and 10 mil drills with 4 mil annular rings."
2015-02-15T08:19:06 < upgrdman> seems shitactular considering their pricing
2015-02-15T08:19:34 < dongs> 10mil is 0.254mm drills
2015-02-15T08:19:37 < dongs> wheres the problem?
2015-02-15T08:19:56 < upgrdman>  + anus ring + clearance?
2015-02-15T08:20:07 < dongs> so you can do 10/18 vias
2015-02-15T08:20:24 < dongs> nothing wrong iwht that
2015-02-15T08:20:28 < upgrdman> k
2015-02-15T08:20:34 < dongs> but i wouldnt push them
2015-02-15T08:20:36 < dongs> just do 0.3/0.5
2015-02-15T08:20:47 < upgrdman> mm?
2015-02-15T08:20:48 < dongs> < dongs> you can do down to 0.85mm pitch with that
2015-02-15T08:20:51 < dongs> sorryi meant 0.65
2015-02-15T08:20:51 < dongs> yes
2015-02-15T08:20:57 < dongs> 0.3mm hole 0.5mm ring
2015-02-15T08:21:45 < dongs> you can route 5/5 between 0.65 and drop via in the center between pads
2015-02-15T08:21:56 < upgrdman> k
2015-02-15T08:22:31 < dongs> anything beyond 10mil drill is basically laser territory and that will make  your shit 20-30% more expensive

2015-02-15T19:13:15 < qyx_> so b1b = not good
2015-02-15T19:13:37 < Laurenceb_> yup - if you want good Rx performance
2015-02-15T19:13:43 < Laurenceb_> Tx works fine
2015-02-15T19:14:15 < Laurenceb_>  C2 has "one-shot" AFC mode, which is even nicer
2015-02-15T19:14:50 < Laurenceb_> automatically resets the AFC if it locks onto something bad
2015-02-15T19:15:21 < Laurenceb_> ive managed to hack the Rev A to do the same
2015-02-15T19:15:44 < qyx_> is there a transceiver which has working afc?
2015-02-15T19:15:46 < Laurenceb_> but setting up the Rx filter chain is a pita as half the WDS settings are missing
2015-02-15T19:15:54 < qyx_> rfm69 modules have it broken too
2015-02-15T19:15:58 < Laurenceb_> ah
2015-02-15T19:16:06 < Laurenceb_> aiui Rev C with one-shot should work
2015-02-15T19:16:22 < Laurenceb_> you set two filters, AFC filter and packet filter
2015-02-15T19:16:44 < Laurenceb_> in normal Rx mode it will use the wide AFC filter and try to lock onto stuff, resetting if its not a packet
2015-02-15T19:17:14 < Laurenceb_> when it finds a packet preamble it will PLL onto the carrier then transition to the narrow packet filter to decode
2015-02-15T19:17:33 < Laurenceb_> thats what the app notes say about rev C2 anyway...
2015-02-15T19:17:53 < Steffanx>  rfm69 broken afc? Any errata for that?

2015-02-15T19:19:42 < qyx_> maybe it is working, but show me at least one implementation using it
2015-02-15T19:20:02 < Laurenceb_> so they dont have an app note for AFC?
2015-02-15T19:20:30 < qyx_> they describe how it should work
2015-02-15T19:20:43 < Laurenceb_> ah, but its known to be buggy?
2015-02-15T19:20:55 < qyx_> uh, officially don't know
2015-02-15T19:21:01 < Laurenceb_> ok
2015-02-15T19:21:07 < Laurenceb_> sounds like a pita
2015-02-15T19:21:12 < Laurenceb_> but so is silabs :P
2015-02-15T19:21:31 < qyx_> i hope that one day someone will make it work
2015-02-15T19:21:35 < Laurenceb_> my custom AFC filter is a bit nicer now :D

2015-02-15T19:22:44 < Laurenceb_> line 434+ is how i handle AFC on  < Rev C
2015-02-15T19:23:11 < Laurenceb_> it seems to work, but i havent fully tested, need to improve my test setup, theres too much Rf leaking around the lab
2015-02-15T19:25:31 < qyx_> " Automatic frequency correction (AFC) should be avoided with this transceiver" hah
2015-02-15T19:25:36 < qyx_> http://www.indigresso.com/wiki/doku.php?id=opentag:radios:sx1231
2015-02-15T19:27:11 < Laurenceb_> can you use LoRa  ?
2015-02-15T19:28:14 < qyx_> actually i was considering doing dsss/psss with rfm69
2015-02-15T19:28:34 < Laurenceb_> interesting
2015-02-15T19:28:54  * Laurenceb_ is working on a narrow band uplink for balloons
2015-02-15T19:29:17 < karlp> jpa-: yeah, I know about pfm/pwm switching at low loads, but I dind't think even they woud get into audio range directly, I assumed it must be something else that causes the buzzing?
2015-02-15T19:33:52 < kakeman> why si446x Laurenceb_ ?
2015-02-15T19:33:55 < jpa-> karlp: i designed one ADC circuit with some maxim PFM boost chip, it was operating at 300Hz when idle and spewing noise all over the data
2015-02-15T19:35:06 < Laurenceb_> kakeman: cuz it has good datasheet performance
2015-02-15T19:36:07 < kakeman> in terms of?
2015-02-15T19:36:43 < jpa-> in terms of datasheets per minute
2015-02-15T19:36:57 < Laurenceb_> heh
2015-02-15T19:37:05 < Laurenceb_> reception at low dBm
2015-02-15T19:37:10 < kakeman> nice
2015-02-15T19:37:14 < Laurenceb_> at low bitrate
2015-02-15T19:37:18 < kakeman> nice
2015-02-15T19:37:42 < Laurenceb_> for balloon uplink you want ~100bps at <<-100dBm
2015-02-15T19:38:08 < kakeman> did it had any competition?
2015-02-15T19:38:53 < kakeman> in those aspects`?
2015-02-15T19:38:59 < Laurenceb_> theres Chipcon transceiver, which need more complex board layout, and LoRa, which people have used for balloon uplink
2015-02-15T19:39:20 < Laurenceb_> but LoRa seems to be vulnerable to interference, as its quite wide

2015-02-15T21:21:32 < Laurenceb_> neve rheard of it before :P

2015-02-16T00:52:21 < Steffanx> How would one do DSSS with a module like the rfm69 qyx_ ? Or do you  apply it to the data and transmit that? But how would that "spread the spectrum"?
2015-02-16T00:54:59 < zyp> I'm curious as well, I'd think it could only do FHSS
2015-02-16T00:57:59 < qyx_> you would only use its mks modulator (qpsk essentially) without packet engine
2015-02-16T00:58:18 < qyx_> feeding data on the gpio pin
2015-02-16T00:58:42 < qyx_> baud rate is configured for the bandwidth after spreading
2015-02-16T00:58:50 < qyx_> and the spreading is done in software
2015-02-16T00:58:58 < qyx_> s/mks/msk
2015-02-16T00:58:59 < zyp> so you're more or less doing SDR at that point
2015-02-16T00:59:12 < qyx_> yep
2015-02-16T01:00:06 < zyp> what's the advantage of doing DSSS rather than FHSS?
2015-02-16T01:00:47 < qyx_> you don't need to lock on the hopping sequence :P
2015-02-16T01:01:19 < zyp> is that a significant advantage? :p
2015-02-16T01:02:07 < qyx_> may be, dsss provides you with relative timing (after doing fht or other transformation)
2015-02-16T01:02:22 < qyx_> i should try if it is possible at least
2015-02-16T01:02:34 < qyx_> using spi to send/receive the bitstream
2015-02-16T01:07:23 < qyx_> Steffanx: also i investigated the doppler thing - it applies to fluids (reflection is used)
2015-02-16T01:16:35 < Steffanx> but the talk was about anemometers.. so no (relevant) reflections(??)
2015-02-16T01:19:16 < qyx_> yep, i was just misled by this false belief

2015-02-16T05:04:57 < dongs> 15

2015-02-16T05:08:47 < jadew> my options are limited
2015-02-16T05:12:47 < jadew> heh, I actually like altium
2015-02-16T05:13:05 < jadew> never used the the other tools tho, like mentor studio & co
2015-02-16T05:13:17 < upgrdman> dongs, laying out those traces in altidongs looks almost as tedious as doing it wiht geda
2015-02-16T05:14:35 < jadew> you sure push the limits on those clearance limits

2015-02-16T05:34:17 < dongs> maybe r2com the shitsoft user will know
2015-02-16T05:41:08 < _Getty> now i understand why the C developers always put so much "resulting numbers" in giant ass arrays into their code..... i mean i do it myself right now

2015-02-16T06:15:32 < dongs> almost time to get back to shit soft
2015-02-16T06:15:40 < upgrdman> i had one get a very small blister. didn't even notice it, but when i took my car in for two new tires they pointed it out
2015-02-16T06:15:41 < dongs> i hate altium so much, i'd  much rather be chatting about using orcad
2015-02-16T06:15:52 < emeb_mac> came out to the car after a day at work - big bubble out the sidewall.
2015-02-16T06:16:14 < emeb_mac> changed it on the spot for the spare, got a new one.

2015-02-16T06:25:41 < upgrdman> flonase is not over-the-counter. why the fuck did they make it so big. a maybe 1oz bottle, sized right, attached to like four inches of mist pumper.

2015-02-16T06:28:55 < upgrdman> excellent for cold/flu
2015-02-16T06:29:06 < upgrdman> and unlike afrin, you don't get addicated to it

2015-02-16T06:32:49 < englishman> eventually there is too much snow

2015-02-16T10:19:11 < PeterM> akaWolf, does that mean people who use lunix should use the arguement "If i am going to use garbage, it may as well be free garbage"?

2015-02-16T12:58:42 < green1> hello,
2015-02-16T12:59:15 < green1> how to add manually downloaded stm32cubeF1 to stm32cubeMx ?
2015-02-16T12:59:30 < jpa-> ask dongs, he is our cube-expert
2015-02-16T13:00:02 < green1> i see, thank you
2015-02-16T13:01:04 < green1> the problem i have, i can't update cubeMx. it doesn't connect to internet  even i'm online.
2015-02-16T13:01:25 < green1> i used, no proxy option. but didn't get connected.
2015-02-16T13:01:36 < green1> so i have to manually add libraries, but i don't know how to do it .
2015-02-16T13:02:01 < green1> hello dongs , u around ?
2015-02-16T13:04:09 < zyp> hmm, this F4 board people asked me to design, looks like I'll be going to use around 30 IOs or so, good thing F407 isn't available in less than a 100pin package then :p
2015-02-16T13:04:58 < zyp> and that's including ethernet
2015-02-16T13:06:00 < dongs> hm?
2015-02-16T13:06:03 < dongs> isnt 30 <100
2015-02-16T13:06:07 < zyp> yes
2015-02-16T13:06:24 < green1> dongs: do u have some advice for me ?
2015-02-16T13:06:25 < zyp> it's just that shit is huge
2015-02-16T13:06:26 < jpa-> zyp is sad to pay for pins he doesn't need :)
2015-02-16T13:06:37 < PeterM> zyp bga
2015-02-16T13:06:41 < dongs> green1: im only good at hating cube
2015-02-16T13:06:49 < PeterM> thats not xbox hueg
2015-02-16T13:06:51 < dongs> zyp, use the same package as on -disco
2015-02-16T13:06:59 < dongs> probly cheapest
2015-02-16T13:07:03 < zyp> yeah, that's the smallest one
2015-02-16T13:07:15 < PeterM> zyp use atmega328p
2015-02-16T13:07:19 < zyp> good idea
2015-02-16T13:12:45 < zyp> huh, I didn't realize that F4 has a 4k backup sram block, in addition to the 80 bytes of backup registers in the RTC block
2015-02-16T13:15:23 < jpa-> yeah
2015-02-16T13:15:35 < jpa-> surprise sram
2015-02-16T13:15:44 < green1> oh, new version of cubeMx have option to load from local .. thank you all.
2015-02-16T13:15:55 < jpa-> i wonder what the access speed is, IIRC the RTC backup reg access is quite slow
2015-02-16T13:17:14 < zyp> dunno
2015-02-16T13:17:20 < zyp> it's mapped on AHB1
2015-02-16T13:17:38 < zyp> while RTC is mapped on APB1
2015-02-16T13:18:16 < jpa-> another extra ram i wonder about is whether any STM32's have ETM trace RAM like LPC17xx has
2015-02-16T13:18:48 < zyp> isn't LPC's trace RAM a repurposable block of normal SRAM?
2015-02-16T13:18:59 < zyp> at least that's how I think it is in LPC43xx
2015-02-16T13:19:27 < jpa-> yeah, i think so
2015-02-16T13:20:10 < specing> jpa-: "surprise, sram"
2015-02-16T13:21:25 < zyp> LPC43xx have four SRAM blocks, half of one block can be used as trace RAM
2015-02-16T13:21:46 < zyp> «When the Embedded Trace Buffer is used (see ETBCFG register, Table 49), the 16 kB memory space at 0x2000 C000 must not be used by any other process.»
2015-02-16T13:24:35 < zyp> I guess stm32 doesn't have ETB

2015-02-16T14:47:56 < jpa-> he has a core dump
2015-02-16T14:48:02 < jpa-> so should be able to get a stack trace from that
2015-02-16T14:48:04 < karlp> no, he got a seg fault
2015-02-16T14:48:10 < karlp> depends on ulimit whether he got a core or not
2015-02-16T14:48:17 < karlp> it says "core dumped" even if it doesn't do it.
2015-02-16T14:48:28 < jpa-> it does? hm, ok
2015-02-16T14:48:30 < karlp> and ubuntu and a few others default to "who the fuck needs these core files anyway?!"

2015-02-16T15:18:55 < dongs> PaulFertser: pascal
2015-02-16T15:19:05 < dongs> but yea, im sure there is.

2015-02-16T15:43:33 < PaulFertser> Yeah, and Atmel decided to collaborate with OpenOCD recently too.
2015-02-16T15:44:13 < karlp> well, not just openocd, putting that massive dump of protocol level stuff out on teh web was a great step
2015-02-16T15:44:37 < karlp> I always think of the old at91 , not new cortex when I see at91
2015-02-16T15:45:33 < PaulFertser> Hehe, yes.
2015-02-16T15:46:13 < PaulFertser> I mean they're planning to directly pay people to work on OpenOCD upstream, it seems.
2015-02-16T15:47:14 < Steffanx> atmel as in .. they're going to add jtag/debugwire/pdi ( or just their programming tools) support for AVRs PaulFertser?
2015-02-16T15:47:20 < Steffanx> or just their arm stuff?
2015-02-16T15:47:46 < PaulFertser> cortex-m, cortex-a, yes. Who cares about avr :)
2015-02-16T15:47:55 < dongs> you can system("stk500.exe") from openocd

2015-02-16T15:49:06 < PaulFertser> Steffanx: I mean now :) btw, OpenOCD can flash atmegas via jtag.
2015-02-16T15:49:14 < Steffanx> Come on, everyone should know (#)#stm32 originated from #avr
2015-02-16T15:50:09 < PaulFertser> I don't know that :)
2015-02-16T15:50:37 < Steffanx> Programming is easy, Atmel has never been very open about the debugging part.

2015-02-16T19:39:22 < jpa-> hmph, the data from STM32 "TPI" (apparently some reduced version of TPIU) does not correspond with format given in http://infocenter.arm.com/help/topic/com.arm.doc.ihi0029d/IHI0029D_coresight_architecture_spec_v2_0.pdf page 129 onwards  (example data i've captured: http://kapsi.fi/~jpa/stuff/pix/stm32_tpiu.png)
2015-02-16T19:39:41 < jpa-> it always sets the trace source to 0x00 which means "ignore"
2015-02-16T19:41:03 < jpa-> even though stm32 ref manual says that it should be as given in IHI0029D

2015-02-16T20:09:02 < PaulFertser> jpa-: hi
2015-02-16T20:09:06 < jpa-> hi
2015-02-16T20:09:36 < PaulFertser> jpa-: you can use out-of-tree openocd support to configure the tpiu and related registers for testing.
2015-02-16T20:10:20 < jpa-> doesn't it just configure TPIU for bypass mode?
2015-02-16T20:10:25 < PaulFertser> jpa-: I can see both plain ITM/DWT output when TPIU formatter is disabled as well as 16-bytes formatter packets when it's enabled.
2015-02-16T20:10:37 < PaulFertser> jpa-: I'm not sure what you mean by bypass mode.
2015-02-16T20:10:44 < jpa-> "formatter disabled"
2015-02-16T20:11:14 < jpa-> ok, so now it supports also formatter enabled; which branch is it?
2015-02-16T20:11:49 < jpa-> formatter disabled works fine for me, but now i'm looking into getting ETM to work so i need the formatter
2015-02-16T20:11:58 < PaulFertser> jpa-: please see http://openocd.zylin.com/#/c/2538/ or http://openocd.zylin.com/#/c/2540/8 (head of the branch)
2015-02-16T20:12:19 < PaulFertser> I hope I've added all the needed docs to the Info manual.
2015-02-16T20:12:50 < jpa-> do you happen to have any captured 16-byte formatter packet anywhere?
2015-02-16T20:13:01 < PaulFertser> jpa-: I'll just grab one right now
2015-02-16T20:16:24 < jpa-> PaulFertser: ah, actually openocd code helped already
2015-02-16T20:16:33 < jpa-> i had forgotten to set ITM trace bus id, thus it was 0
2015-02-16T20:18:05 < PaulFertser> jpa-: http://paste.debian.net/149851/ (had formatter turned off, then turned it on)
2015-02-16T20:18:30 < jpa-> thanks, may be handy later
2015-02-16T20:18:45 < jpa-> seems TPIU is now working as expected after setting the bus id
2015-02-16T20:18:51 < jpa-> PaulFertser: have you done anything with ETM yet?
2015-02-16T20:19:39 < PaulFertser> jpa-: not yet, just took a look at the docs and the existing OpenOCD code.
2015-02-16T20:20:06 < PaulFertser> jpa-: regarding the code, I hope it'll get merged into OpenOCD upstream eventually, so your feedback would be much appreciated.
2015-02-16T20:20:08 < jpa-> i'm having trouble figuring out whether stm32f100 is even supposed to have ETM.. the registers just read 0 :)
2015-02-16T20:21:10 < jpa-> PaulFertser: ok, though i don't currently have stlinkv2 and only slow serial dongles
2015-02-16T20:22:22 < PaulFertser> jpa-: how do you capture currently? I've added "external" capture mode just so one can use whatever additional device he has.
2015-02-16T20:24:35 < jpa-> logic analyzer
2015-02-16T20:25:12 < jpa-> i'm approaching from a bit different direction than the openocd support

2015-02-16T20:25:55 < PaulFertser> jpa-: yeah, so OpenOCD should be perfectly suitable to configure the target appropriately, that's one of the usecases I had in mind.
2015-02-16T20:26:27 < PaulFertser> jpa-: there's also a handy library for ITM decoding http://git.zapb.de/
2015-02-16T20:27:03 < jpa-> well configuring for ITM is just 10 lines of code anyway
2015-02-16T20:27:35 < jpa-> bah, "Most STMicroelectronics Cortex-M3/M4 parts are equipped with ETM."  but nowhere it says which
2015-02-16T20:31:17 < PaulFertser> jpa-: yes, though preparing that branch still took me considerable time. I hope to have usable and useful UI and internal API eventually.
2015-02-16T20:31:50 < jpa-> PaulFertser: yeah, i can understand the API point of view from openocd side, it is always more complex to do something generically
2015-02-16T20:32:11 < jpa-> hmm, looks like stm32f100 doesn't have ETM, but stm32f105 should have it
2015-02-16T20:33:10 < jpa-> and stm32l151 has it also
2015-02-16T20:33:46 < jpa-> now i just have to remember if i have any board that i could use for testing this.. maybe i should have bought stm32l1 discovery some time :P
2015-02-16T20:35:00 < PaulFertser> jpa-: you can read the ROM table to verify, "dap info"

2015-02-16T20:35:16 < PaulFertser> It lists (or not) ETM there.
2015-02-16T20:35:34 < PaulFertser> It's strange they say in stm32f100 RM that ETM depends on pin count.

2015-02-16T20:36:28 < jpa-> is "dap info" some openocd command or do i have to decode the rom table manually?

2015-02-16T20:38:06 < PaulFertser> jpa-: openocd command, yes, works with any low-level adapter.
2015-02-16T20:38:15 < PaulFertser> Or do you have stlinkv1 there?
2015-02-16T20:38:55 < PaulFertser> Then there's out-of-tree patch to avoid parsing manually.
2015-02-16T20:39:07 < jpa-> yeah, i only have stlinkv1 :F

2015-02-16T20:48:13 < jpa-> PaulFertser: might be nice if stlink-v1.cfg would automatically do "transport select hla_swd"
2015-02-16T20:48:37 < jpa-> my old scripts no longer worked because i had to add that
2015-02-16T20:50:13 < jpa-> and yeah, indeed no ETM on STM32F100; i'll try with STM32F105 some other day
2015-02-16T20:51:23 < PaulFertser> jpa-: but stlink can in theory support hla_jtag too.
2015-02-16T20:52:58 < jpa-> Error: Debug adapter doesn't support 'jtag' transport
2015-02-16T20:53:04 < jpa-> in theory but not in practise?
2015-02-16T20:53:06 < PaulFertser> Also, I'm not sure if that's good for consistency with the other configs or not, probably it's fair to "train" user to always select a transport. OTOH we added "transport select swd" to all the jtag->swd adapters.
2015-02-16T20:53:42 < PaulFertser> In practice it would require someone to extend stink driver and it doesn't seem to be a single reason to use stlink in jtag mode.

2015-02-16T20:56:12 < jpa-> can't one override the transport afterwards anyway? swd seems like a reasonable default when jtag is not even supported
2015-02-16T20:57:16 < PaulFertser> jpa-: yes, it's annoying but we had to do that. And no, unfortunately current architecture doesn't allow any dynamic reconfiguration of adapter or transport at all.
2015-02-16T20:57:19 < PaulFertser> Or targets.
2015-02-16T20:57:28 < jpa-> hmm
2015-02-16T20:58:14 < PaulFertser> jpa-: it was decided to default to jtag because OpenOCD is a JTAG tool, and it was jtag-only for long time.
2015-02-16T20:58:37 < PaulFertser> Also, unfortunately, there's "swd" and "hla_swd" and those are completely different beasts.
2015-02-16T20:59:20 < PaulFertser> Because with stlink you're not working on swd level actually, but on high level (a bit lower than the gdb serial protocol).
2015-02-16T21:02:23 < jpa-> PaulFertser: how about making target/swj-dp.tcl work like this: http://paste.dy.fi/fle/plain

2015-02-16T21:06:46 < jpa-> then it would fall back to swd when the adapter doesn't support jtag
2015-02-16T21:22:03 < PaulFertser> jpa-: hm, interesting idea, it seems to cover pretty much all current usecases.
2015-02-16T21:25:04 < PaulFertser> jpa-: I'll make a patch and push for review, thank you very much, this seems to be quite reasonable behaviour.

2015-02-17T03:15:03 < Getty> oh ok, i take it back..... i just didnt realized that time_t is actually signed............ <doh>
2015-02-17T03:17:03 < qyx_> you either aren't using -Wall -Wextra or you ignored the warning
2015-02-17T03:17:40 < qyx_> ah you explicitly casted
2015-02-17T03:18:24 < qyx_> btw you shouldn't do operations on time_t
2015-02-17T03:18:32 < qyx_> it is even stated in the manpage
2015-02-17T03:19:13 < Getty> i actually just did a time_t < time_t, but my mistake was that i was setting "forever" to a very high number, one that actually was making it negative
2015-02-17T03:19:28 < Getty> but as i never thought about it being signed, i always debugged it via unsigned operations.... those told me different things

2015-02-17T03:20:54 < Getty> i mean the look on my face must have been priceless when i saw the if being clearly wrong about the compare ;-) (in my eyes)
2015-02-17T03:21:48 < qyx_> there is a diff function for comparing them
2015-02-17T03:22:00 < dongs> timediff.php
2015-02-17T03:22:47 < qyx_> back to pro coding
2015-02-17T03:23:06 < qyx_> i just found out why my rtc is not counting
2015-02-17T03:23:10 < qyx_> no clock selected
2015-02-17T03:23:15 < Getty> yeah saw that in between, but now where i treat it like signed its anyway fine, but i switch to that function (or thinking about to stop using time_t.....)
2015-02-17T03:23:38 < qyx_> you cannot treat it in any way because its size/signedness is not defined
2015-02-17T03:24:06 < qyx_> time_t is used to hide things you shouldn't mess with
2015-02-17T03:24:21 < qyx_> use proper functions for manipulating it
2015-02-17T03:25:25 < _Sync_> dongs: the hdd reprogramming shit is amazeballs
2015-02-17T03:28:03 < qyx_> Getty: for generic math operations use things from stdint, that includes comparing values.. max/min values are also defined there

2015-02-17T13:26:14 < zyp> hey, question about PCBA for this F4 shit
2015-02-17T13:26:28 < zyp> I guess the rj45 for ethernet will have to be PTH
2015-02-17T13:27:12 < zyp> and then I'm going to need female header connections on the bottom for stacking on top of the board this is going to be installed on, would it be preferable to have them be PTH or SMT?
2015-02-17T13:28:55 < dongs> hm
2015-02-17T13:29:03 < dongs> i dont think we have selective solder
2015-02-17T13:29:09 < dongs> shit just gets dipped
2015-02-17T13:29:19 < dongs> so connectors on the bottom would be kinda fail
2015-02-17T13:29:39 < dongs> or if its not that many can just handsolder RJ45
2015-02-17T13:32:21 < qyx_> i like handsoldering rj45
2015-02-17T13:32:22 < jpa-> no SMD RJ45?
2015-02-17T13:33:08 < zyp> dongs, «we» as in korea or what?
2015-02-17T13:34:09 < dongs> zyp, either here or there
2015-02-17T13:34:29 < zyp> the arcin batches looks like they're soldered by selective wave
2015-02-17T13:34:36 < dongs> no, they're taped
2015-02-17T13:34:38 < dongs> lol
2015-02-17T13:34:45 < dongs> masking tape on bottom
2015-02-17T13:34:48 < zyp> oh
2015-02-17T13:36:56 < zyp> well, ok, I guess smt connectors on bottom would be preferable then
2015-02-17T13:38:01 < dongs> ya whichever works, will figure out which way is better
2015-02-17T13:40:23 < zyp> hmm, there's a bunch of SMT RJ45, but I don't think I'd trust the mechanical strength of anything that doesn't have PTH pins on the shroud at least
2015-02-17T13:42:20 < qyx_> how much of those boards you will need?
2015-02-17T13:42:31 < qyx_> *many
2015-02-17T13:45:13 < zyp> dunno, right now they'll pay me for the design and a proto run of 10
2015-02-17T13:45:44 < qyx_> pff, get china-made tht
2015-02-17T13:45:49 < qyx_> and handsolder
2015-02-17T13:46:10 < zyp> yeah, I could handsolder RJ45 on ten boards if I had to :p
2015-02-17T13:46:45 < zyp> but I wouldn't want to do that on the following 100 boards or whatevery they'll order :p
2015-02-17T13:48:10 < zyp> oh well, I'll work on that shit later
2015-02-17T13:48:19 < zyp> today I'm going to figure out why the fuck my car won't start
2015-02-17T14:17:23 < dongs> if youre just making 10 i wouldnt even care
2015-02-17T14:17:26 < dongs> just do wahtever.
2015-02-17T14:17:33 < dongs> ill just charge you more for being a cunt
2015-02-17T14:21:59 < zyp> :p
2015-02-17T14:22:50 < zyp> found a loose wire to the throttle position sensor in my car
2015-02-17T14:23:06 < zyp> so now I'll just have to figure out where my crimp tool is so I can fix it
2015-02-17T14:23:21 < Steffanx> Still the good old volvo zyp?
2015-02-17T14:23:26 < zyp> yep
2015-02-17T14:23:27 < dongs> sounds like you almost got toyota'd
2015-02-17T14:23:39 < zyp> heh
2015-02-17T14:24:09 < zyp> it's kinda hard to have that runaway problem in a manual transmission car
2015-02-17T14:24:35 < zyp> I'll just step on the clutch and then no power gets to the wheels either way

2015-02-17T14:36:20 < englishman> no difference to the user
2015-02-17T14:36:23 < englishman> about the same price
2015-02-17T14:36:33 < englishman> if youre programming a bunch need lunix / vm

2015-02-17T15:07:01 < englishman> congrats
2015-02-17T15:07:39 < Laurenceb> i suspect i can gain another 2dB and 0.2ppm tuning range by reducing the FSK deviation
2015-02-17T15:08:00 < Laurenceb> ive got samples of revision C2 silicon now
2015-02-17T15:08:15 < Laurenceb> but farnell have it in stock
2015-02-17T15:08:41 < Laurenceb> the front end is 3dB already

2015-02-17T18:03:07 < Steffanx> i meant: there is an example project using libopencm3
2015-02-17T18:06:09 < Laurenceb> hmm i might try this
2015-02-17T18:06:11 < Laurenceb> http://www.st.com/web/en/resource/technical/document/application_note/CD00264379.pdf
2015-02-17T18:06:36 < Laurenceb> aiui the application code just needs an NVIC_SystemReset command
2015-02-17T18:06:39 < Laurenceb>  ?
2015-02-17T18:09:32 < jpa-> don't you have to do the BOOT0 thingy?
2015-02-17T18:09:45 < englishman> iirc theres one in here
2015-02-17T18:09:45 < englishman> https://github.com/jihlein/FF32lite
2015-02-17T18:09:48 < jpa-> unless you jump into the bootloader instead of reset
2015-02-17T18:09:49 < englishman> or another from this dev
2015-02-17T18:10:17 < jpa-> Laurenceb: ah, you mean running the F4 bootloader on F1? the USB is totally different
2015-02-17T18:10:44 < Laurenceb> oops
2015-02-17T18:10:50 < Laurenceb> lol
2015-02-17T18:11:03 < Laurenceb> yeah my F103 is in a sealed enclosure
2015-02-17T18:11:12 < Laurenceb> there is only a USB port on the front
2015-02-17T18:11:55 < jpa-> do you have any internal storage?
2015-02-17T18:12:11 < jpa-> or maybe steal dso quad's bootloader :P
2015-02-17T18:12:30 < Laurenceb> no theres no storage
2015-02-17T18:12:40 < Laurenceb> F103 and si446x dongle
2015-02-17T18:14:36 < englishman> Laurenceb: theres one in st f1 examples, for some devboard
2015-02-17T18:14:48 < englishman> i took that and added it to proj, iirc it fit in 4k page
2015-02-17T18:14:54 < englishman> then jumped to it when i wanted
2015-02-17T18:15:30 < Laurenceb> ok
2015-02-17T18:15:45 < englishman> maybe it was an f3 example i ported
2015-02-17T18:16:18 < Laurenceb> the way the st bootloader for F4 works seems useful
2015-02-17T18:16:25 < Laurenceb> as it doesnt need a boot button
2015-02-17T18:16:42 < englishman> STM32_USB-FS-Device_Lib_V4.0.0
2015-02-17T18:16:44 < englishman> one of these examples
2015-02-17T18:16:48 < Laurenceb> ok
2015-02-17T18:17:03 < englishman> f10x
2015-02-17T18:17:18 < Getty> why noone mentioned the blackmagic yet? doesnt that also fit as reference for his needs?

2015-02-17T18:31:56 < Steffanx> but how hard would be to not use a button
2015-02-17T18:32:09 < Laurenceb> well you have to work out when to enter bootloader

2015-02-17T18:42:11 < Laurenceb> so when i plug in it doesnt get bombarded with modem stuff
2015-02-17T18:42:16 < Laurenceb> blackmagic manages it
2015-02-17T18:42:21 < Laurenceb>  ... somehow
2015-02-17T18:42:43 < Laurenceb> cdc_acm 3-1:1.2: This device cannot do calls on its own. It is not a modem.
2015-02-17T18:44:23 < gxti> are you sure networkmangler doesn't probe it anyway despite that message?
2015-02-17T18:44:53 < gxti> i remember needing to actually delete modemmanager to keep it from doing that shit at some point, not sure if it still is
2015-02-17T18:45:50 < Laurenceb> ah
2015-02-17T18:46:14 < Laurenceb> still, i seem to be missing some config somewhere

2015-02-17T19:08:45 < Laurenceb> but i dont understand what i need to do to the application code?
2015-02-17T19:09:28 < Getty> what you mean?
2015-02-17T19:09:35 < Getty> oh! yeah thats in the .ld file
2015-02-17T19:09:54 < Getty> the .ld file sets where the application is set

2015-02-17T19:12:15 < Laurenceb> no
2015-02-17T19:12:23 < Laurenceb> how is the bootloader called
2015-02-17T19:12:45 < Laurenceb> as it is my blackmagic probe is just two CDCACM devices
2015-02-17T19:12:52 < Laurenceb> it has to become a DFU device
2015-02-17T19:12:52 < Getty> well if you wanna call the bootloader from the main application you just jump to the 08000000
2015-02-17T19:12:57 < Laurenceb> yeah
2015-02-17T19:13:13 < Laurenceb> but doesnt a special value need to be set in ram?
2015-02-17T19:13:17 < Getty> no?
2015-02-17T19:13:21 < Getty> its all garbage

2015-02-17T19:13:27 < Getty> who cares what is in?
2015-02-17T19:13:33 < Steffanx> it uses a button by default iirc
2015-02-17T19:13:34 < Laurenceb> i cant find any of this in the blakcmagic code
2015-02-17T19:13:35 < Getty> did you cared about when you powered it on? ;)

2015-02-17T19:16:20 < Steffanx> im not, my bmp has a button and it goes into dfu mode when i press it.
2015-02-17T19:16:25 < Steffanx> and reset

2015-02-17T19:17:01 < Laurenceb> i only have a clone
2015-02-17T19:18:05 < Getty> well button does what it is attached to ;-) and if you are only working with own boards you don't know that much of common buttons ;)
2015-02-17T19:18:26 < Getty> always irritating for me that very often the people talking here just "assume" that some common board is used and it actually works out that way ;-)

2015-02-17T19:34:25 < trepidaciousMBR> What's the best way of driving step and dir to a stepper motor driver from an STM32? Hopefully there is some way of producing a set number of pulses from a pin, probably a timer?
2015-02-17T19:37:06 < GargantuaSauce> there are a few approaches
2015-02-17T19:37:09 < GargantuaSauce> how many steppers?
2015-02-17T19:37:24 < trepidaciousMBR> Probably 4
2015-02-17T19:38:17 < GargantuaSauce> if you have four timers available that's probably the way to go, use each of them to control the pulse rates and their ISRs to count pulses
2015-02-17T19:38:36 < trepidaciousMBR> Yup, just seems like that leads to a lot of interrupts
2015-02-17T19:39:09 < trepidaciousMBR> I guess DMA to the timers would give me an interrupt every N steps, and you could even change some timer parameter to change the step rate
2015-02-17T19:39:28 < trepidaciousMBR> Can you get an interrupt per N timer overflows?
2015-02-17T19:39:41 < GargantuaSauce> not without slaving one timer to another i think
2015-02-17T19:41:27 < trepidaciousMBR> Yeah I seem to remember you can get a timer to count overflows on another timer
2015-02-17T19:42:41 < GargantuaSauce> only a subset of the timers support that i think, and you probably dont have 8 anyway
2015-02-17T19:42:42 < trepidaciousMBR> I think the DMA might not be too bad, there's an ST example using a similar approach I think, I could just have a reasonable length buffer and interrupt handler would keep track of the steps, and set up the DMA again, it could use a shorter length for the remainder
2015-02-17T19:42:54 < trepidaciousMBR> GargantuaSauce: Yup it seems a shame to waste that many timers
2015-02-17T19:43:20 < GargantuaSauce> you could also consider doing dma straight to the gpio, driven by a timer at maybe 2x the max stepping rate
2015-02-17T19:43:32 < GargantuaSauce> will use a bit of memory though
2015-02-17T19:44:18 < trepidaciousMBR> Yup, that might not be bad actually, I've not done DMA to GPIO, can you do it for just 4 pins?
2015-02-17T19:46:21 < GargantuaSauce> yeah by writing to BSRR
2015-02-17T19:48:11 < trepidaciousMBR> That might be pretty nice actually, use a timer to drive DMA to GPIO, the DMA interrupt could update the timer for acceleration/deceleration and set the DMA going again
2015-02-17T19:48:21 < GargantuaSauce> yup
2015-02-17T19:48:23 < trepidaciousMBR> with only 1 timer for up to 32 steppers I guess
2015-02-17T19:48:43 < GargantuaSauce> well, 16
2015-02-17T19:48:48 < trepidaciousMBR> ah yup
2015-02-17T19:49:11 < trepidaciousMBR> I'll have to give that a go with a scope, see if it looks about right :)
2015-02-17T19:50:42 < trepidaciousMBR> Shouldn't be an unreasonable amount of SRAM either
2015-02-17T19:51:17 < trepidaciousMBR> Would that work on an STM32F4xx ?

2015-02-17T23:54:44 < zyp> debugged a fun issue in some other guy's code today
2015-02-17T23:54:51 < zyp> code that «used to work»
2015-02-17T23:55:54 < zyp> random faults, pc holding 0xfffffff8
2015-02-17T23:57:45 < zyp> turns out that while «mov pc, lr» works to return in a normal case, it doesn't work when lr holds EXC_RETURN, so it'll fault when it tries to return from an ISR
2015-02-17T23:58:48 < zyp> and it so happened that a function attempting to return like that was tail-called from some other stuff in an ISR

2015-02-18T00:00:29 < zyp> replacing «mov pc, lr» with «bx lr» solved the problem
2015-02-18T00:02:15 < gxti> user wrote the mov instruction?
2015-02-18T00:02:21 < gxti> or was it something gcc generated?
2015-02-18T00:02:43 < zyp> user
2015-02-18T00:02:48 < zyp> some lowlevel assembly stuff
2015-02-18T00:02:52 < gxti> silly
2015-02-18T00:03:09 < zyp> well, it worked for all other returns :p
2015-02-18T00:03:28 < gxti> it's clearly not the way that ARM intended people to return from functions!
2015-02-18T00:03:34 < gxti> but i guess that's only obvious now
2015-02-18T00:03:49 < gxti> is the bytecode the same size?
2015-02-18T00:03:53 < zyp> well, I knew it, but I didn't write that code
2015-02-18T00:04:03 < zyp> sure, all thumb instructions are 16 bit

2015-02-18T02:17:42 < qyx_> also i am seeking an algo to make an unix timestamp from the rtc
2015-02-18T02:17:42 < zyp> karlp, I guess you're free to select your own datum
2015-02-18T02:18:17 < Laurenceb_> qyx_: check my github
2015-02-18T02:18:22 < qyx_> ok, maybe not, i cannot do utc timestamp, it doesn't handle leap seconds
2015-02-18T02:18:27 < qyx_> Laurenceb_: O_o
2015-02-18T02:18:40 < Laurenceb_> it doesnt handle leap seconds lol
2015-02-18T02:19:07 < gxti> utc timescale includes leap seconds, the only ones that don't are "non civil" ones like GPS, TAI, etc
2015-02-18T02:19:21 < qyx_> yes, but stm32 rtc doesn't
2015-02-18T02:19:26 < zyp> qyx_, we had an i2c rtc with a similar time/date format for a projct once
2015-02-18T02:19:38 < gxti> well, they're not predefined. if you want to do them you have to actually change the clock.
2015-02-18T02:19:44 < qyx_> at least i didn't find it in the refman, i suppose i am supposed to implement it myself
2015-02-18T02:19:51 < zyp> and somebody found an mktime implementation, so I just used that
2015-02-18T02:20:03 < gxti> it's not like leap years where there is an algorithm to translate back and forth
2015-02-18T02:20:10 < qyx_> i know
2015-02-18T02:20:17 < gxti> so i'm not sure what you're expecting :p
2015-02-18T02:20:20 < qyx_> they could include a predefined table :P
2015-02-18T02:20:26 < zyp> same
2015-02-18T02:20:34 < Laurenceb_> https://github.com/Laurenceb/STM32-Logger/blob/master/Util/fat_fs/src/rtc.c
2015-02-18T02:20:41 < zyp> leap seconds is something I'd just ignore if I could
2015-02-18T02:20:43 < gxti> predefined to whatever was current at manufacture time? that's pretty useless
2015-02-18T02:21:13 < gxti> anyway, can you really keep time to within a second over the course of several years on a RTC anyway?
2015-02-18T02:21:16 < zyp> and if I couldn't, I'd still ignore them and stick to gps time instead, and handle translation to utc on demand
2015-02-18T02:21:25 < zyp> no
2015-02-18T02:21:39 < gxti> so either it gets out of sync or you just sync to something else that implements it...
2015-02-18T02:21:57 < qyx_> ok ok, forget about leap seconds :P
2015-02-18T02:22:21 < gxti> never!
2015-02-18T02:25:25 < zyp> looks like 20ppm is a typical value for rtc crystals
2015-02-18T02:25:34 < zyp> 20ppm of a year is around ten and a half minute
2015-02-18T02:26:01 < zyp> so yeah, what gxti said
2015-02-18T02:27:01 < qyx_> quite much
2015-02-18T02:27:21 < zyp> the only reason you should care about it is if you're doing something where the time being a second wrong between the leap second and the next sync is unacceptable
2015-02-18T02:27:44 < qyx_> i assume that for simple logging purposes it will be more than enough :P
2015-02-18T02:27:50 < zyp> yeah
2015-02-18T02:29:35 < zyp> I can't really imagine a situation when you require that precision, and still use realtime rather than monotonic time

2015-02-18T03:13:48 < yan_> I'm having trouble figuring out why my cortex m3 is faulting in the pendsv handler. I'm seeing consistent faults in FreeRTOS' pendsv handler after it tries to 'bx lr'.. lr is set to 0xfffffffd, but it works most of the time (as in, it branches correctly), until a certain task, then it faults. does this sound familiar to anyone?
2015-02-18T03:15:19 < zyp> 0xfffffffd is EXC_RETURN
2015-02-18T03:15:44 < zyp> it's a magic value that instructs the cpu to do an interrupt return instead of a plain function return
2015-02-18T03:16:09 < zyp> so that much is normal behavior
2015-02-18T03:16:15 < yan_> zyp: why would it be faulting then? this is happening inside an isr
2015-02-18T03:16:34 < zyp> that I can't say, you've not given enough information
2015-02-18T03:16:57 < zyp> did you check SCB_CFSR to see which kind of fault you're getting?
2015-02-18T03:18:10 < yan_> Yep, (i checked a bit ago, about to retry) but i'm pretty sure it was set to UNDEFINSTR
2015-02-18T03:18:14 < yan_> i.e. == 1
2015-02-18T03:18:40 < yan_> going to go check what the semantics of EXC_RETURN are
2015-02-18T03:19:39 < zyp> it's something like «pop all scratch registers, lr and pc from the stack»
2015-02-18T03:20:32 < yan_> zyp: hm i'd need to check those semantics manually, since it pops+branches in a single instruction
2015-02-18T03:20:42 < zyp> also, 1 is IACCVIOL, UNDEFINSTR is 0x10000
2015-02-18T03:21:39 < zyp> sounds like the popped pc value might be garbage

2015-02-18T09:34:25 < yan_> I'm trying to disable an interrupt with NVIC_DisableIRQ() (not on an stm32, but also cortex m3) but the interrupt is still being invoked. am i missing something as to the semantics of NVIC_DisableIRQ()?
2015-02-18T09:40:52 < jpa-> maybe you are passing the wrong kind of interrupt number to it?
2015-02-18T09:41:44 < jpa-> though it is the same as NVIC_EnableIRQ()
2015-02-18T09:41:53 < jpa-> so if you manage to enable it, disabling should work also
2015-02-18T09:43:51 < yan_> jpa-: does it matter which order i call disable and clearpending in?
2015-02-18T09:44:31 < jpa-> not AFAIK

2015-02-18T09:49:37 < jpa-> this 3g modem in this system is just so wtf
2015-02-18T09:49:54 < jpa-> it has built-in http, but you can only request 1500 bytes of the response at a time
2015-02-18T09:50:08 < jpa-> and each request takes hundreds of milliseconds for it to process
2015-02-18T09:50:19 < jpa-> so it's transferring at like 10kB/s
2015-02-18T10:04:51 < Roklobsta> are you using AT commands to get and send tcp/udp packets?
2015-02-18T10:05:00 -!- whateverman is now known as bourbon
2015-02-18T10:05:19 < Roklobsta> i have done that before except the damned packets were limited to 512bytes.  Thanks, Telit.
2015-02-18T10:05:38 < jpa-> nah, this is using AT commands to transfer HTTP stuff
2015-02-18T10:05:42 < jpa-> http is done on the modem
2015-02-18T10:05:49 < Roklobsta> ah ok.
2015-02-18T10:06:18 < Roklobsta> i used to do it for UDP packets on a commercial product on GPRS.
2015-02-18T10:06:20 < Roklobsta> sloooooooooow
2015-02-18T10:06:22 < Roklobsta> laggy
2015-02-18T10:06:30 < Roklobsta> especially when the voice channels on a tower got busy
2015-02-18T10:07:23 < Roklobsta> i tried it breifly with a 3G modem and there was a big improvement
2015-02-18T10:07:55 < Roklobsta> what make and model of modem are you using?
2015-02-18T10:08:52 < jpa-> cinterion something
2015-02-18T10:09:17 < Roklobsta> is it cheap and craptacular?
2015-02-18T10:09:36 < jpa-> i have no idea
2015-02-18T10:09:43 < jpa-> i'm just the one who all bugs fall on
2015-02-18T10:13:04 < Roklobsta> oh yeah.,  well AT based IP transactions are fine for 8 bit stuff.
2015-02-18T10:13:28 < Roklobsta> If you are using an STM32 can you retrofit LWIP and use your own PPP session?
2015-02-18T10:13:42 < Roklobsta> that'd be much faster
2015-02-18T10:13:50 < jpa-> probably yeah
2015-02-18T10:14:02 < jpa-> we'll see how important the customer feels it is
2015-02-18T10:14:23 < jpa-> more interesting would be whether STM32F1 would be fast enough for reasonable SSL
2015-02-18T10:15:37 < Roklobsta> the telit module i was using supported SSL and I managed to get it working using an AVR.
2015-02-18T10:16:24 < Roklobsta> i have the code still I think.
2015-02-18T10:16:32 < Roklobsta> if you want it
2015-02-18T10:16:55 < Roklobsta> a whole bunch of AT commands to set up an ssl session in the modem itself.
2015-02-18T10:17:04 < Roklobsta> the AVR had no chance.
2015-02-18T10:19:54 < jpa-> probably no use for this
2015-02-18T10:20:15 < jpa-> this modem supports SSL also, but the transfer speed is too slow due to the stupid AT command design
2015-02-18T10:20:35 < jpa-> but the manual is thousand pages, maybe i'll find a way around it

2015-02-18T20:28:44 < zyp> the point of having separate MSP and PSP is to allow you to keep a separate stack for interrupt handlers
2015-02-18T20:29:18 < zyp> because otherwise you'd have to allocate room for interrupt handling in every thread stack, in case and interrupt happened during execution of that thread

2015-02-19T00:15:43 < specing> or even better, GNAT
2015-02-19T00:15:53 < green1> i used to use, mikroc.
2015-02-19T00:16:04 < green1> i find all these are complex.
2015-02-19T00:16:22 < green1> mikroc has simple, API for peripharal drivers

2015-02-19T00:20:17 < specing> thats 4 times as many bits, what did you expect?
2015-02-19T00:20:28 < brabo> green1: look at libopencm3
2015-02-19T00:20:53 < Lux> you could try stm32 cube, it has some sort of code generator etc
2015-02-19T00:21:00 < Lux> never tried it tough
2015-02-19T00:21:04 < brabo> better than std periph lib

2015-02-19T00:29:40 < englishman> they are moving to stm32cubemx which generates keil projects but older chips are supported with stdperiphlib no prob

2015-02-19T00:32:49 < green1> englishman: the problem i have, when i enable keil middleware driver, which enable CMSIS.
2015-02-19T00:33:04 < englishman> yeah so dont.
2015-02-19T00:33:26 < englishman> you already have cmsis with stdperiphlib
2015-02-19T00:33:46 < green1> but, keil middleware needs it's own CMSIS enabled
2015-02-19T00:35:53 < englishman> right
2015-02-19T00:36:10 < englishman> you can still ahve dbugging and all that without the keil middleware getting in the way
2015-02-19T00:37:39 < englishman> you're using st's version of all that instead of keil's
2015-02-19T00:38:38 < englishman> iirc you can even pull in stdperiph stuff from within keil with 'software packs'
2015-02-19T00:39:00 < englishman> and keil extensions like usb/network stuff

2015-02-19T00:48:59 < englishman> yeah actually i was just dicking witht that
2015-02-19T00:49:01 < englishman> works great
2015-02-19T00:49:23 < green1> how ? please tell me the link
2015-02-19T00:49:25 < englishman> tick boxes for each library you want to pull in
2015-02-19T00:49:27 < englishman> in keil?
2015-02-19T00:49:39 < englishman> click on the green toolbar button "pack installer"
2015-02-19T00:49:42 < green1> but, it has no GPIO driver
2015-02-19T00:49:47 < green1> for stm32
2015-02-19T00:49:54 < englishman> then in your project "manage run-time environment"
2015-02-19T00:50:02 < englishman> device -> gpio
2015-02-19T00:50:17 < englishman> along with startup and other stdperiph drivers
2015-02-19T00:50:30 < green1>  i see, interesting, i will find it
2015-02-19T00:51:24 < englishman> then all you gotta do is add chip define (example STM32F10X_MD) and USE_STDPERIPH_DRIVER
2015-02-19T00:51:27 < englishman> and main() of course
2015-02-19T00:51:35 < englishman> built a hex immediately
2015-02-19T00:57:08 < green1> i see, via this method i can access, all other  std drivers like ADC ?
2015-02-19T00:57:34 < englishman> yeah theyre all in there
2015-02-19T00:59:31 < green1> cool, i got your point, i will check it

2015-02-19T01:18:46 < green1> do u have any idea ?
2015-02-19T01:19:12 < green1> maybe  because differnt cmsis version ?
2015-02-19T01:20:50 < englishman> what did you put in main.c
2015-02-19T01:21:19 < englishman> and what chip
2015-02-19T01:21:54 < englishman> oh
2015-02-19T01:21:59 < englishman> did you include rcc
2015-02-19T01:22:10 < green1> i had to,  i did..
2015-02-19T01:22:11 < englishman> if some boxes are yellow you have to check em
2015-02-19T01:22:21 < green1> none,

2015-02-19T01:22:40 < englishman> hmh
2015-02-19T01:23:14 < englishman> i just made new stm32f103cb project, included adc and rcc, core, framework, startup, added main(), added USE_STDPERIPH_DRIVER define, and it compiles

2015-02-19T01:57:19 < qyx_> dumb question, is it possible to recover from hardfault?
2015-02-19T01:57:32 < qyx_> all internet codez just do while (1) in the handler
2015-02-19T01:59:27 < qyx_> mhm, actually all my other tasks keep running
2015-02-19T01:59:33 < qyx_> and the hardfault handler is entered periodically
2015-02-19T02:00:08 < qyx_> i assume i could just kill the current task
2015-02-19T02:02:08 < zyp> if you're planning to recover from faults, you should probably do that in the configurable fault handlers before letting it be promoted to a hardfault
2015-02-19T02:02:53 < zyp> and yes, fault handlers aren't any more magic than other interrupts
2015-02-19T02:03:09 < qyx_> "You can recover from a hardfault interrupt by just exiting the interrupt. The code will continue but use a wrong value."
2015-02-19T02:03:12 < qyx_> hmm
2015-02-19T02:03:25 < zyp> it's just that if the fault condition persists, it'll just be retriggered immediately when you exit
2015-02-19T02:03:47 < gxti> obviously you don't return to the faulted code, you kill the task and trigger a context switch
2015-02-19T02:04:07 < zyp> that's not always obvious
2015-02-19T02:04:14 < qyx_> i would like to, but my freertos don't like this for some reason
2015-02-19T02:04:16 < qyx_> uh
2015-02-19T02:04:24 < zyp> depends on the sort of the fault, and your environment
2015-02-19T02:04:25 < qyx_> so i just need to add return from interrupt to my naked handler?
2015-02-19T02:04:44 < zyp> you could have a fault trigger an exception and start the unwinding procedure
2015-02-19T02:05:05 < qyx_> i have this so far https://pastee.org/yynrs
2015-02-19T02:05:24 < gxti> hrm, what happens if you have 'return' in a naked function?
2015-02-19T02:05:47 < zyp> it returns, I assume
2015-02-19T02:05:57 < zyp> i.e. bx lr

2015-02-19T04:37:46 < emeb_mac> so does that maple crap actually have a usable IDE for STM32 dumbed down for Arduino-like stuff?
2015-02-19T04:39:14 < dongs> yes
2015-02-19T04:39:20 < dongs> except the "usable" part
2015-02-19T04:39:24 < emeb_mac> heh
2015-02-19T04:39:25 < dongs> it is really just arduino IDE
2015-02-19T04:39:49 < emeb_mac> with wrappers and libs targeting stm32 I guess
2015-02-19T04:43:54 < emeb_mac> sounds like it's not in development any more though

2015-02-19T04:52:06 < kakeman> is there anything ncurses like libraries for mcus?
2015-02-19T04:53:06 < qyx_> what do you expect?
2015-02-19T04:53:09 < hesperaux> if I use alarmmanager to fire a pending intent repeatedly, and I start this alarm on boot, is it okay to also start the alarm when the user starts the app? From what I read on the docs, a duplicate PendingIntent will not override a previous alarm schedule because the intent is the same (this is what I'm hoping for).
2015-02-19T04:53:11 < kakeman> nope
2015-02-19T04:53:27 < qyx_> i mean what do you expect from such library
2015-02-19T04:53:47 < kakeman> some basic menus
2015-02-19T04:53:55 < kakeman> some graphics
2015-02-19T04:54:12 < kakeman> lines and stuff
2015-02-19T04:54:34 < qyx_> i don't know of any
2015-02-19T05:00:05 < dongs> i bet if tectu was around....
2015-02-19T05:00:51 < qyx_> kakeman probably wants a textual version
2015-02-19T05:01:00 < qyx_> as thats what ncurses is
2015-02-19T05:01:42 < hesperaux> one time, I joined ##stm32 and thought I was in #android-dev, and wondered why nobody was answering my question, and wondering why people were talkinga bout MCUs. Then I was an idiot
2015-02-19T05:02:08 < qyx_> hesperaux: i was about to ask if thats android
2015-02-19T05:02:12 < qyx_> such intents
2015-02-19T05:02:34 < hesperaux> lol
2015-02-19T05:02:51 < hesperaux> talk about a different way of thinking compared to embedded!
2015-02-19T05:03:01 < hesperaux> waste memory here, inflate the call stack here
2015-02-19T05:04:34 < GargantuaSauce> android sure does embrace hedonism as a design pattern
2015-02-19T05:05:13 < hesperaux> lol
2015-02-19T05:05:20 < PeterM> poor performance? fuck it, qualcomm will throw more hardware at it
2015-02-19T05:06:04 < hesperaux> I wince a lot while coding, but I have come to accept it as a different way of life
2015-02-19T05:06:22 < hesperaux> Once I embraced the way things are for app design, I got a lot more done
2015-02-19T05:06:32 < hesperaux> I miss embedded though
2015-02-19T05:08:20 < kakeman> ncurses requires some posix features of platform
2015-02-19T05:08:36 < GargantuaSauce> i wouldn't try and port ncurses, it's surprisingly heavyweight
2015-02-19T05:09:19 < kakeman> ye
2015-02-19T05:09:20 < dongs> so it will run on nuttx then
2015-02-19T05:09:21 < GargantuaSauce> implementing simple functionality like you're looking for (for a single type of terminal) would be very straightforward though
2015-02-19T05:09:34 < kakeman> yes
2015-02-19T05:09:48 < kakeman> simple menus
2015-02-19T05:10:09 < kakeman> it should be

2015-02-19T15:18:26 < Steffanx> the parrot kept you awake this night?
2015-02-19T15:18:31 < dongs> and dudes walk in and like "give me number 23"

2015-02-19T15:20:53 < Steffanx> ok, so it's not that
2015-02-19T15:21:04 < jpa-> maybe it was messing up with ETM yesterday
2015-02-19T15:21:22 < jpa-> didn't find register definitions so had to write my own.. damn that thing has a lot of regs
2015-02-19T15:21:33 < Laurenceb> pervert parrot?

2015-02-19T15:22:20 < jpa-> Steffanx: nope, not many enough to bother with that
2015-02-19T15:23:41 < Steffanx> What's your plan with the swo stuff in sigrok btw? Just show the data in sigrok or are you also going to do some fancy plotting?
2015-02-19T15:23:46 < jpa-> http://koti.kapsi.fi/jpa/stuff/other/etm_cm3.h
2015-02-19T15:24:10 < jpa-> just to present it in a readable form so that one can figure out what the code is doing at each point
2015-02-19T15:24:47 < jpa-> not sure if there is much to plot about it, but one can of course get it out as text from sigrok
2015-02-19T15:25:15 < zyp> what's the benefit of piping it through sigrok then?
2015-02-19T15:25:41 < jpa-> zyp: to decode it?
2015-02-19T15:26:03 < zyp> oh, from a logic analyzer input?
2015-02-19T15:26:05 < jpa-> i.e. if you want to get PC addresses from the trace stream, just grep for "PC" after my code has decoded that from the ITM binary format
2015-02-19T15:26:06 < jpa-> yeah
2015-02-19T15:26:15 < jpa-> did you see the early screenshot?
2015-02-19T15:26:19 < zyp> ah, I was thinking trace-capable hardware
2015-02-19T15:26:20 < zyp> no
2015-02-19T15:26:29 < zyp> url?
2015-02-19T15:26:50 < jpa-> http://koti.kapsi.fi/jpa/stuff/pix/sigrok_swo.png
2015-02-19T15:27:20 < jpa-> myself i'm most interested in seeing it against the other logic analyzer signals, i.e. "now happened this on the IO pins, what caused it?"
2015-02-19T15:27:31 < zyp> yeah, that sounds pretty useful
2015-02-19T15:28:23 < jpa-> ITM/DWT is mostly done and finished fishing out TPIU bugs yesterday, next up is decoding ETM packets
2015-02-19T15:28:36 < Laurenceb> is this going to be open source?
2015-02-19T15:28:41 < jpa-> sure
2015-02-19T15:28:46 < Laurenceb> nice :D
2015-02-19T15:29:02 < jpa-> the hardware i'm using is 24MSps saleae clone that cost some $15 on ebay
2015-02-19T15:29:11 < Laurenceb> heh i have one of those
2015-02-19T15:30:05 < _Sync_> wtf ist that display dongs
2015-02-19T15:30:14 < _Sync_> 30:9 or wat?
2015-02-19T15:32:36 < dongs> sync, yeah its some common advertisement shit
2015-02-19T15:32:44 < dongs> i saw them in a lot of stores/shops
2015-02-19T15:33:05 < dongs> i didnt know the shit ran assdroid tho
2015-02-19T15:33:10 < dongs> usually they just slideshow some static crap
2015-02-19T15:34:20 < _Sync_> well why not assdroid that shit
2015-02-19T15:34:23 < _Sync_> easier to develop for
2015-02-19T15:35:32 < Laurenceb> why not µGFX
2015-02-19T15:35:36 < Laurenceb>  /troll
2015-02-19T15:37:15 < Steffanx> With a huge animated gif? I believe ugfx can render animated gifs.
2015-02-19T15:38:05 < Steffanx> Wouldnt be surprised if that android thing was just a fullscreen browser page with some fancy HTML5/canvas stuff
2015-02-19T15:38:32 < dongs> duhg
2015-02-19T15:38:36 < dongs> why would it be anything else
2015-02-19T15:38:48 < dongs> the whole reason one would use assdroid for that is so tehy c ould just fullscreen loldongs.swf or something
2015-02-19T15:38:52 < dongs> inside some shitty player
2015-02-19T15:39:08 < Steffanx> oh flash is even better
2015-02-19T15:40:29 < Steffanx> You know better than me anyway, you are into the display stuff and in this country you dont see many displays like that in shops
2015-02-19T15:42:22 < zyp> hmm, is AD15 worth upgrading to?
2015-02-19T15:42:26 < dongs> no
2015-02-19T15:43:15 < zyp> "support for rectangular pad holes"
2015-02-19T15:43:16 < zyp> hardcore
2015-02-19T15:43:20 < dongs> that didtn work
2015-02-19T15:43:26 < dongs> i made a fucking pcb with rectangular shit
2015-02-19T15:43:31 < dongs> and  it came back from fab with a hole
2015-02-19T15:43:35 < zyp> heh
2015-02-19T15:43:35 < dongs> and rectangular copper cleared around it
2015-02-19T15:44:32 < zyp> oh well, doesn't look like anything useful, so I'll not bother installing that today
2015-02-19T15:45:01 < dongs> nothing useful
2015-02-19T15:45:05 < dongs> and they fucked up 3d view
2015-02-19T15:45:20 < zyp> heh
2015-02-19T15:45:32 < dongs> teh new xsignals shit is probably the only useful thing
2015-02-19T15:45:38 < dongs> if only it could do other stuff properly
2015-02-19T15:49:40 < Laurenceb> perman00b c question
2015-02-19T15:49:53 < Laurenceb> how do i create a pointer to an array of 5 bytes?
2015-02-19T15:50:03 < Laurenceb> without using two variables or using malloc
2015-02-19T15:50:04 < jpa-> int myarray[5]; int *myptr = myarray;
2015-02-19T15:50:15 < jpa-> you mean const array then?
2015-02-19T15:50:18 < Laurenceb> yeah is there another way?
2015-02-19T15:50:23 < Laurenceb> yes
2015-02-19T15:50:45 < jpa-> you can do     myfunnyfunction((const int[]){1,2,3,4,5})  which is useful sometimes
2015-02-19T15:51:00 < Laurenceb> hmm
2015-02-19T15:51:15 < jpa-> which is pretty much the same as   const int foo[] = {1,2,3,4,5}; myfunnyfunction(foo);
2015-02-19T15:51:59 < Laurenceb> if i declare an array i cant make it point to NULL
2015-02-19T15:52:03 < Laurenceb> thats my problem
2015-02-19T15:52:07 < Laurenceb> i want to do
2015-02-19T15:52:17 < Laurenceb> int* foo[5];
2015-02-19T15:52:30 < Laurenceb> if(bar){foo=NULL;}
2015-02-19T15:52:52 < Laurenceb> do i need an array and a pointer?
2015-02-19T15:53:26 < zyp> const int* shit = (const int[]){1, 2, 3};
2015-02-19T15:53:31 < zyp> or something
2015-02-19T15:54:07 < zyp> and yes, what you're asking for is a pointer pointing to an array
2015-02-19T15:54:20 < jpa-> yeah, what zyp said
2015-02-19T15:54:45 < jpa-> but remember that the pointer would be invalid after you exit the block where you created it
2015-02-19T15:55:39 < zyp> would it actually?
2015-02-19T15:56:17 < zyp> I'd expect a const array like that to be emitted in .rodata, like a string literal
2015-02-19T15:56:53 < scummos> yes, I would expect that in rodata as well
2015-02-19T15:56:59 < jpa-> yeah, i would expect that also
2015-02-19T15:57:03 < scummos> it's not really different from a string literal, is it
2015-02-19T15:57:12 < jpa-> but i can't find much info on lifetimes of const compound literals
2015-02-19T15:57:39 < jpa-> so not sure if it is undefined behaviour or not
2015-02-19T15:57:55 < zyp> probably better to be explicit and make a global symbol for it
2015-02-19T15:59:12 < Laurenceb> ok
2015-02-19T15:59:25 < zyp> hey, anybody know off the top of their head which GPIOs exist on the 100pin-package of f407, so I don't have to count them? :p
2015-02-19T16:00:05 < zyp> at a glance it looks like A-E exists in full
2015-02-19T16:00:32 < zyp> and PH0/1 for OSC_IN/OUT
2015-02-19T16:01:09 < zyp> okay, that's 82 and it claims to have 82 GPIOs, so I assume that's correct
2015-02-19T16:07:29 < trepidaciousMBR> Laurenceb: http://www.st.com/web/catalog/sense_power/FM142/CL851/SC1794/SS1498/LN1723/PF248592?sc=internet/analog/product/248592.jsp looks nice
2015-02-19T16:08:14 < Laurenceb> oh nice
2015-02-19T16:08:20 < Laurenceb> i wrote that for F4 lol
2015-02-19T16:08:35 < trepidaciousMBR> Yeah I was thinking I might have to, good old ST saving me the work :)
2015-02-19T16:08:48 < Laurenceb> https://github.com/Laurenceb/Chibi-Spectro/blob/master/threads/EKF_Pressure.c
2015-02-19T16:09:07 < trepidaciousMBR> This board looks handy, not sure how to get one: https://strawberry-linux.com/images/l6470-set.jpg
2015-02-19T16:10:09 < trepidaciousMBR> Laurenceb: Cool, how did you drive the stepper itself?
2015-02-19T16:10:30 < Laurenceb> an A4988 iirc
2015-02-19T16:10:52 < Laurenceb> https://github.com/Laurenceb/Chibi-Spectro/blob/master/hardware/Image0009.jpg
2015-02-19T16:10:55 < Laurenceb> looks like it
2015-02-19T16:11:32 < trepidaciousMBR> Ah cool, then something to do with GPIO for driving the step/dir from the look of it?
2015-02-19T16:11:40 < Laurenceb> yes
2015-02-19T16:11:47 < Laurenceb> timer pwm for the steps
2015-02-19T16:14:50 < Laurenceb> that project was a nightmare lol
2015-02-19T16:15:07 < dongs> < trepidaciousMBR> This board looks handy, not sure how to get one: https://strawberry-linux.com/images/l6470-set.jpg
2015-02-19T16:15:14 < dongs> you could just clone it :)
2015-02-19T16:15:18 < dongs> that is pretty neat
2015-02-19T16:15:18 < Laurenceb> pity the L6470 wasnt around
2015-02-19T16:15:29 < trepidaciousMBR> Yeah it looks really simple, I like the idea of bolting it to the motor ;)

2015-02-19T16:16:11 < trepidaciousMBR> Laurenceb: Yeah I was so glad to find that, should save me a load of time, plus I have to drive 4-8 steppers, so I would probably have run out of timers or had to have multiple MCUs ;)
2015-02-19T16:16:17 < Laurenceb> figure 10 is what half of that code is for lol
2015-02-19T16:16:24 < Laurenceb> yeah
2015-02-19T16:16:54 < Laurenceb>  F4 is fast... but it does get quite demanding if you want single step accuracy

2015-02-19T16:19:39 < Laurenceb> actually
2015-02-19T16:19:48 < Laurenceb> you could use DMA and maybe timer gating
2015-02-19T16:20:08 < trepidaciousMBR> I was wondering about DMA to the timer, there's an ST AN using that I think
2015-02-19T16:20:14 < Laurenceb> i ran out of timers as i was doing some 7 subcarrier OFDM stuff
2015-02-19T16:20:21 < trepidaciousMBR> you can have acceleration/deceleration in the DMA buffer
2015-02-19T16:20:24 < Laurenceb> yes
2015-02-19T16:20:38 < dongs> fuck that. just put a F4 on the back of every pcb
2015-02-19T16:20:42 < dongs> and bolt it to the motor
2015-02-19T16:20:44 < Laurenceb> my problem was that i couldnt pre plan moves
2015-02-19T16:20:48 < Laurenceb> heh
2015-02-19T16:20:57 < Laurenceb> as it was pressing on peoples arms
2015-02-19T16:21:07 < trepidaciousMBR> Laurenceb: Yeah I would have had to do something odd for seeking to home sensor
2015-02-19T16:21:08 < Laurenceb> and they tend to move by themsleves...
2015-02-19T16:21:19 < trepidaciousMBR> Laurenceb: Cool, that sounds like an interesting application ;)
2015-02-19T16:21:23 < trepidaciousMBR> robo-prodder ;)
2015-02-19T16:21:28 < Laurenceb> so it had to replan optimal trajectory at 400hz
2015-02-19T16:21:34 < Laurenceb> pretty much thats what it does
2015-02-19T16:21:34 < trepidaciousMBR> Nice
2015-02-19T16:22:05 < trepidaciousMBR> So the pressure it is monitoring is on the end of the prodding stick?

2015-02-19T21:39:50 < _Sync_> still iffy
2015-02-19T21:39:57 < _Sync_> look at the larger traces
2015-02-19T21:40:01 < zyp> http://bin.jvnv.net/f/TgK0Q.JPG <- old pic of something I did
2015-02-19T21:40:02 < _Sync_> even those have shit
2015-02-19T21:40:05 < zyp> looks way better
2015-02-19T21:40:16 < _Sync_> yup
2015-02-19T21:40:32 < GargantuaSauce> yeah the impression i've gotten is that oshpark's quality varies quite a bit
2015-02-19T21:40:47 < Steffanx> because different fabs are used.. ?
2015-02-19T21:40:54 < GargantuaSauce> probably
2015-02-19T21:41:05 < Steffanx> not sure if that applies to the 4 layer board though
2015-02-19T21:41:12 < Steffanx> *boards
2015-02-19T21:41:19 < zyp> ah, mine was 4 layer
2015-02-19T21:41:23 < GargantuaSauce> i would hope it's that and not just poor process control or whatever
2015-02-19T21:41:32 < Steffanx> that pic is also a 4 layer one
2015-02-19T21:42:52 < GargantuaSauce> http://www.eevblog.com/forum/projects/pcb-fab-hackvana-vs-oshpark/
2015-02-19T21:44:03 < GargantuaSauce> 3 bad runs
2015-02-19T21:44:33 < englishman> hackvana just orders from cutrate china pcb shops
2015-02-19T21:44:38 < englishman> why dont people just cut out the middleman
2015-02-19T21:45:05 < GargantuaSauce> yeah funny how their board was way better
2015-02-19T21:46:16 < englishman> However all 10mil hits were upsized to 13/14mil by the fab, resulting in catastrophic breakout.
2015-02-19T21:46:18 < englishman> thats not good
2015-02-19T21:46:23 < englishman> with advertised 10mil drills
2015-02-19T21:46:43 < GargantuaSauce> the issues all look like obvious blunders that'd be solved with basic qc to me
2015-02-19T21:46:48 < GargantuaSauce> kind of unsettling
2015-02-19T21:46:48 < _Sync_> englishman: because it is not that easy to actually reach chinese cutrate fabs without being there
2015-02-19T21:47:28 < englishman> i havent used these guys http://www.safe-pcb.com/ but you can quote/order online even
2015-02-19T21:50:16 < _Sync_> oh
2015-02-19T21:50:24 < _Sync_> they can do thick copper
2015-02-19T21:50:29 < _Sync_> that's a plus

2015-02-19T22:10:50 < karlp> fuck knows, gotta either find a CE cert somewhere, or "give them permission" to resend it
2015-02-19T22:11:22 < GargantuaSauce> or call it an engineering sample perhaps?
2015-02-19T22:11:46 < karlp> not sure I can swing that now they've already decided,
2015-02-19T22:11:52 < karlp> would have been a better idea in the first place...

2015-02-19T22:12:54 < zyp> oh, you've bought that?
2015-02-19T22:14:09 < karlp> yeah, bought that, it's arrived, they asked for the invoice, now they're saying, "after further inspection, this isn't CE marked. so, according to some law from 2007, youcan't have it.  There are no exceptions. Talk to the post and communications office if you want to know more.  Please give us permission to return it to the sender"

2015-02-19T22:15:58 < karlp> gah. that's really put a damper on my night :|
2015-02-19T22:16:07 < Steffanx> tiem for a beer
2015-02-19T22:16:28 < ds2> don't worry, the EU will collapse soon :D
2015-02-19T22:16:31 < zyp> *yawn*
2015-02-19T22:16:42 < zyp> picking parts have to be the most boring part of designing pcbs
2015-02-19T22:16:53 < Steffanx> its not really the EU .. the dutch customs dont really care :P
2015-02-19T22:17:02 < ds2> no eu, no ce
2015-02-19T22:17:04 < ds2> ;)
2015-02-19T22:17:42 < Steffanx> then we'll go FCC ( or something) and be even more screwed?
2015-02-19T22:18:22 < ds2> that's a second problem
2015-02-19T22:18:36 < zyp> I wonder if I can just hook the reset lines of the phy and the stm32 together to have the phy reset when the stm32 does
2015-02-19T22:18:42 < ds2> but the FCC is not imminimently toppling over
2015-02-19T22:18:51 < zyp> or if that's a horribly bad idea for some reason
2015-02-19T22:20:34 < karlp> apparently there are plenty of exceptions, if I read the actual law.
2015-02-19T22:20:50 < karlp> if I can convince them it's for a ship, for starters.
2015-02-19T22:21:00 < zyp> heh
2015-02-19T22:21:10 < zyp> well, is it?
2015-02-19T22:21:19 < karlp> depends how big a boat it needs to be...
2015-02-19T22:21:28 < karlp> I guess I could carve up a plank of wood big enough for it?
2015-02-19T22:21:30 < Getty> well you can just add it ;-)
2015-02-19T22:22:07 < karlp> radio hobbyists have a special exception too, but only if it's not bought on the regular market.
2015-02-19T22:22:27 < ds2> this makes me wonder (OT) - how do they designate a beta test in greece
2015-02-19T22:22:27 < Steffanx> zyp, dont some phys require you to reset it for x miliseconds? Could be annoying if your stm32 resets and the phy doesnt
2015-02-19T22:22:32 < Getty> in the end its only relevant that you really fall into the CE accepted values, its not that relevant that its actually tested for this
2015-02-19T22:23:14 < karlp> Getty: no, it's only relevant whether customs can see the letters, nothing at all about actual test results.
2015-02-19T22:23:28 < Getty> exactly, just wanted to mention that
2015-02-19T22:23:49 < zyp> Steffanx, looks like stm32 will hold it low for at least 20us when it's generating the reset pulse
2015-02-19T22:23:58 < karlp> well, yes, we all know that CE is only self declared anyway.
2015-02-19T22:24:27 < zyp> Steffanx, I'm mostly concerned about power on reset, which is part of what stm32 handles internally
2015-02-19T22:24:30 < Getty> these days you also have to add the not-trashcan symbol ;)
2015-02-19T22:25:38 < zyp> Getty, what if what you're making is so shitty it doesn't deserve to go elsewhere?
2015-02-19T22:26:21 < Getty> zyp: well it just says that you are not allowed to put it in the trashcan, meaning, its so bad that even the trashcan is too good for it, or something
2015-02-19T22:26:23 < Getty> ;-)
2015-02-19T22:26:58 < zyp> oh, and the phy requires at least 500us for a warm reset
2015-02-19T22:27:36 < zyp> ok, guess I'll just forget that then
2015-02-19T22:31:18 < karlp> heh, they say it's banned to put a mark that looks like the CE mark :)
2015-02-19T22:34:34 < Getty> oh yeah, its probably more criminal to make a fake CE then just making a real fake CE ;-)
2015-02-19T22:35:05 < Getty> why is this topic so funny?
2015-02-19T22:36:21 < gxti> zyp: nrst line definitely gets pulled low on software-commanded system reset, because i found a bug in blackmagicprobe where it was driving reset high and it kept the reset from working
2015-02-19T22:36:39 < zyp> I know it does
2015-02-19T22:36:49 < gxti> however, i connected phy reset to a gpio and wiggle it myself
2015-02-19T22:37:07 < zyp> I just wired up a resistor and cap
2015-02-19T22:37:24 < zyp> if I need to reset it from the mcu, I can do that over MDIO
2015-02-19T22:41:58 < karlp> well, Asked the seller if they can "come up" with some CE docs

2015-02-20T00:38:27 < zyp> what kind of messages?
2015-02-20T00:38:43 < zyp> doesn't your rtos of choice provide this?
2015-02-20T00:39:41 < qyx_> there are message queues, but they can't be used as a publish-subscribe
2015-02-20T00:39:53 < qyx_> maybe i should try events
2015-02-20T00:41:37 < zyp> well, for a one to many approach, each receiver kinda needs it's own queue
2015-02-20T00:42:36 < zyp> so just use what you have and make a layer on top which can subscribe receiver queues to a list, and then a dispatcher that publishes messages to all subscribed queues
2015-02-20T00:42:45 < qyx_> yep and one message router which will have all queues registered
2015-02-20T00:43:45 < zyp> the painful part is dealing with full queues :p

2015-02-20T03:15:35 < dongs> and one of the ends will look uglyrough
2015-02-20T03:15:50 < zyp> as long as they fit into shrouded sockets
2015-02-20T03:16:04 < zyp> but that's probably not a problem
2015-02-20T03:16:22 < dongs> should be fine, wont know till monday but I dont see why not
2015-02-20T03:16:22 < zyp> hmm, but position is important, so I'd prefer some with alignment pins
2015-02-20T03:16:51 < zyp> http://portal.fciconnect.com/Comergent//fci/drawing/91618.pdf <- like this shit
2015-02-20T03:18:20 < zyp> also, what's a good buck regulator for 12->5V?
2015-02-20T03:18:58 < dongs> i'm using RT7257B replacement RT8293B
2015-02-20T03:19:14 < dongs> its kinda big i guess w/coil
2015-02-20T03:19:19 < dongs> but you have space?
2015-02-20T03:19:36 < dongs> hm those with boss hole, i'd have to ask, but anywa,y its probably possible.

2015-02-20T03:21:15 < zyp> currently looks like that
2015-02-20T03:21:23 < zyp> lacks power and RJ45
2015-02-20T03:21:36 < zyp> and a couple of buttons and leds, I guess
2015-02-20T03:21:58 < dongs> zano-worthy
2015-02-20T03:22:03 < dongs> why dont you just LM1117
2015-02-20T03:22:16 < dongs> how big are those passives
2015-02-20T03:22:17 < dongs> 0603?
2015-02-20T03:22:21 < zyp> yeah
2015-02-20T03:22:21 < dongs> they loookhueg
2015-02-20T03:22:24 < dongs> maybe just me
2015-02-20T03:22:33 < zyp> it's the box around them
2015-02-20T03:22:48 < zyp> I've considered making it thinner and moving it closer around the pads
2015-02-20T03:23:39 < zyp> hmm, I need to change the footprint for the rtc crystal as well
2015-02-20T03:23:54 < dongs> FC-135 i used on teh dildo is tiny
2015-02-20T03:23:58 < dongs> (rtc xtal)
2015-02-20T03:23:58 < zyp> what's the usual footprint for SMT 32k crystals?

2015-02-20T03:25:31 < zyp> and I assume both variants of that phy is available?
2015-02-20T03:25:49 < dongs> which?
2015-02-20T03:25:57 < zyp> the one you suggested last I asked
2015-02-20T03:26:09 < dongs> wasnt that teh shit qyx or wahtever uses?

2015-02-20T03:26:15 < dongs> gimme part# ill tell you again
2015-02-20T03:26:18 < dongs> but last i checked it was yes
2015-02-20T03:26:42 < zyp> KSZ8081RNA
2015-02-20T03:27:03 < zyp> (or RND)
2015-02-20T03:27:27 < dongs> mnx is
2015-02-20T03:27:29 < zyp> RNA seems preferable since it only requires a crystal, not external oscillator
2015-02-20T03:27:43 < zyp> mnx?
2015-02-20T03:27:51 < dongs> hmm actually both about same, shitty avail
2015-02-20T03:27:53 < dongs> i dont think it was that

2015-02-20T03:28:30 < dongs> fff
2015-02-20T03:29:03 < zyp> ksz8081rnaca was what I found in my irc log
2015-02-20T03:29:19 < zyp> so that's what I made a footprint for
2015-02-20T03:31:01 < dongs> seems some people have it, i wouldnt know for sure till monday
2015-02-20T03:31:04 < dongs> not very popular part, tho
2015-02-20T03:31:36 < dongs> if all fails, digikey has a ton :)
2015-02-20T03:31:40 < dongs> and still quite cheap
2015-02-20T03:32:20 < zyp> ah, right
2015-02-20T03:32:48 < zyp> got any suggestion for RJ45 with magnetics?
2015-02-20T03:33:19 < gxti> 8081 is the replacement to 8031, it's pin compatible. there's still the 25mhz xtal vs 50mhz no-xtal thing, but that's just default. pretty sure you can use SMI to change it afterwards.
2015-02-20T03:33:20 < dongs> i only used dumb rj45 for DMX
2015-02-20T03:33:37 < zyp> gxti, yeah, I read that

2015-02-20T03:34:32 < zyp> I'd prefer to have magnetics in the socket
2015-02-20T03:35:04 < gxti> you can get compatible ones from china if you're super cheap

2015-02-20T03:39:43 < gxti> looks like the hanrun jack has the same wiring as the one i linked, but only 6 pins instead of 8. you could make a footprint that takes either.
2015-02-20T03:39:53 < gxti> pulse one has gnd on a pin while hanrun has it on shield
2015-02-20T03:40:05 < zyp> six? hanrun datasheet I have open have 8

2015-02-20T07:52:42 < dongs> this dude is trying to convince me you can have an adapter (active perhaps) that would split 16x pcie into two x8
2015-02-20T07:54:51 < PeterM> you can, http://www.plxtech.com/products/expresslane/switches
2015-02-20T07:56:19 < dongs> where is a product using this
2015-02-20T07:57:38 < PeterM> basically every 2x gpus on 1card solution ever
2015-02-20T07:57:53 < dongs> im talkin shit i can plug in somewhere
2015-02-20T07:58:03 < dongs> im wasting a 16x slot for 8x card
2015-02-20T07:58:08 < dongs> and I could use another x8 card to plug into it
2015-02-20T07:58:32 < dongs> all i can find is retarded passive adapters
2015-02-20T07:58:35 < dongs> for buttcoin shit
2015-02-20T07:58:42 < PeterM> you couldsign the NDA, get the chip and make a breakout board *not actually suggesting that*
2015-02-20T07:58:48 < dongs> lewl
2015-02-20T07:58:51 < dongs> yea lemme get right on that
2015-02-20T07:59:16 < PeterM> 0.1"headers, tarduino sp[acing
2015-02-20T08:00:52 < PeterM> i guess you could mke something to take 1x pcie 1x + 1x pcie 16x and make 2x 8x slots, taking t5he  ctrl signals from the 1x nad grafting them on to the additinal lanes some how
2015-02-20T08:01:16 < dongs> i dont think that would work
2015-02-20T08:01:38 < dongs> if this was possible easily or cheap, stuff would exist
2015-02-20T08:03:19 < PeterM> ive seen people combine 2x 1x slots to make a 2x slot
2015-02-20T08:03:26 < PeterM> but never the splitting
2015-02-20T08:04:08 < dongs> that worked? i kinda doubt it
2015-02-20T08:04:19 < dongs> also is there even anything 2x
2015-02-20T08:04:24 < dongs> it goes 1x 4x 8x
2015-02-20T08:05:08 < dongs> hah
2015-02-20T08:05:13 < dongs> apparently some SSDs are in x2 slot
2015-02-20T08:05:34 < dongs> http://www.apricorn.com/vel-solox2.html
2015-02-20T08:05:37 < dongs> whatever the fuck this is
2015-02-20T08:06:44 < dongs> maybe its like this http://www.amazon.co.jp/dp/B000FHVJBW
2015-02-20T08:07:17 < dongs> http://archive.kuroutoshikou.com/products/etc/no-pci-express.html or this
2015-02-20T08:07:24 < PeterM> nah that is somethign differnt
2015-02-20T08:10:52 < PeterM> what do yu want to split the slto for nyway? more vidya cards?
2015-02-20T08:11:38 < dongs> no, more raid cards
2015-02-20T08:11:42 < dongs> who gives a shit about video
2015-02-20T08:11:56 < dongs> ill just buy a shitty 1x>16x buttcoin adapter for now and suck it up
2015-02-20T08:13:12 < PeterM> dongle why no stick vidya card in 1x slot and put HBA in vidya card slot?
2015-02-20T08:13:24 < dongs> > onboard video
2015-02-20T08:13:27 < PeterM> ahh
2015-02-20T08:13:33 < dongs> raid is already in 16x
2015-02-20T08:13:33 < dongs> heh
2015-02-20T08:14:07 < PeterM> you can cut out the back of a 1x slot and stick it straight in there no need for butt coin aderpder
2015-02-20T08:14:28 < GargantuaSauce> kinda ghetto but i was just going to suggest that
2015-02-20T08:14:38 < dongs> well yeah
2015-02-20T08:14:52 < dongs> or i could cut the raid card down to 1x
2015-02-20T08:14:56 < dongs> ALSO WORKS
2015-02-20T08:15:18 < PeterM> except if you cut down raid card you never get 16x back
2015-02-20T08:15:30 < dongs> 8x
2015-02-20T08:15:31 < dongs> but yeah
2015-02-20T08:15:36 < PeterM> but if you remove small plastic from back of slto oyu can put watever the fuck you want
2015-02-20T08:18:28 < PeterM> lol http://s964.photobucket.com/user/otterinator/media/IMG_20130128_210113.jpg.html soemone done fucked up[
2015-02-20T08:18:54 < dongs> oopsie
2015-02-20T08:19:20 < PeterM> hurr durr ill pull out cardwithout releasing the latch, ill pull as hard as i can
2015-02-20T08:19:36 < dongs> he's in luck tho, thats totally fixable
2015-02-20T08:19:41 < dongs> just finish pulling it off hten snip all the pins out
2015-02-20T08:20:06 < PeterM> yeah
2015-02-20T08:20:26 < PeterM> but judging by the fuckup on the slot, hes probably nt htat smart

2015-02-20T08:49:43 < upgrdman> with shit that uses a voltage divider to sense, like the feedback loop of an boost converter... if you want to use a pot, is the only safe thing to do is add a cap between wiper and ground for the times when the wiper bounces/looses conact?
2015-02-20T08:50:08 < jpa-> that doesn't make it quite safe
2015-02-20T08:50:13 < upgrdman> i cant write when im tried :(
2015-02-20T08:50:17 < upgrdman> ya
2015-02-20T08:50:27 < upgrdman> weak pull + cap?
2015-02-20T08:50:40 < jpa-> one safe way is to make a normal resistor divider, and put the potentiometer in parallel with one of the resistors
2015-02-20T08:50:54 < jpa-> then even if the pot totally fails, you'll have a predictable value
2015-02-20T08:50:59 < upgrdman> o ok
2015-02-20T08:51:02 < upgrdman> cool
2015-02-20T08:51:20 < upgrdman> and you use the pot just as a variable resistor, right? (wiper + one leg)
2015-02-20T08:51:21 < dongs> use a dual nfet and a jumper: http://i.imgur.com/wB3vTrM.png
2015-02-20T08:51:28 < jpa-> weak pull to "inactive state" + cap is a reasonably safe way also
2015-02-20T08:51:32 < jpa-> upgrdman: yeah
2015-02-20T08:51:42 < dongs> why u no use digital pot
2015-02-20T08:51:47 < dongs> i2c-conTROLLed
2015-02-20T08:52:15 < jpa-> in either case if the pot skips, you'll get some transients in the output

2015-02-20T08:52:46 < upgrdman> dongs, im making a shiity breakout / test pcb for a little boost ic. figure i might as well make the output voltage adjustable, so will use pot instead of two resistors.
2015-02-20T08:53:27 < dongs> then just use a pot and dont adjust it while its running
2015-02-20T08:53:35 < dongs> or use one of those enclosed bourns multiturn pots
2015-02-20T08:53:40 < dongs> that china uses on dc/dc converters
2015-02-20T08:53:50 < dongs> dont over enginerer it
2015-02-20T08:54:06 < upgrdman> ya, i don't plan to adjust while on. i just don't have experience with this and didn't want to do it a retarded way
2015-02-20T08:54:16 < upgrdman> multiturn pots dont have wiper issues?
2015-02-20T08:54:33 < dongs> shitton of industrial supplies have just your standard garbage pots on them and I've never seen one fail
2015-02-20T08:54:46 < dongs> all china dc/dc shits on ebay have multiturn stuff and i doubt that fails either
2015-02-20T08:54:47 < upgrdman> ok good
2015-02-20T08:54:50 < jpa-> multiturn pots are usually a bit more reliable yeah, mostly because the wiper is not as directly coupled to the shaft
2015-02-20T08:55:40 < jpa-> it's quite easy to make normal pots fail if you have a shaft and no mechanical support to it.. just one idiot pressing the shaft and the pot becomes unreliable

2015-02-20T14:54:17 < Laurenceb> so when it writes the subaddress, i get subaddress, 0x00, re start
2015-02-20T14:54:24 < Laurenceb> only at certain speeds
2015-02-20T14:54:31 < Laurenceb> its some sort of race condition somewhere
2015-02-20T14:54:53 < Laurenceb> time to check my code and the ref manual :-/
2015-02-20T14:56:56 < Laurenceb> or maybe I2C <-> NVIC timing difference

2015-02-20T14:59:11 < Laurenceb> itd help if i understood how interrupt signalling worked
2015-02-20T14:59:19 < Laurenceb> surely a rising edge is needed?
2015-02-20T14:59:45 < zyp> depends whether it's an edge triggered interrupt or level triggered
2015-02-20T14:59:55 < zyp> I think most if not all IRQs are level triggered
2015-02-20T15:01:02 < Laurenceb> ok
2015-02-20T15:01:04 < Laurenceb> hmm
2015-02-20T15:01:19 < Laurenceb> so i clear the interrupt on line 133

2015-02-20T15:03:23 < Laurenceb> thats the only bug i can see :S
2015-02-20T15:03:56 < jpa-> Laurenceb: so you are getting spurious repeated start also?
2015-02-20T15:04:04 < Laurenceb> no
2015-02-20T15:04:12 < Laurenceb> just an extra byte
2015-02-20T15:04:20 < jpa-> you want the extra start? where do you generate that?
2015-02-20T15:05:18 < Laurenceb> line 108
2015-02-20T15:06:25 < Laurenceb> the rep start and read all runs ok
2015-02-20T15:06:42 < zyp> uh, don't you have to generate that a byte or two before the end?
2015-02-20T15:07:11 < Laurenceb> i dont see that in the ref manual?
2015-02-20T15:07:27 < Laurenceb> search for EV8_2
2015-02-20T15:08:10 < zyp> oh, right, it's when you're reading you have to do that

2015-02-20T15:08:59 < Laurenceb> as i see it it can only be a second byte being sent from line 127
2015-02-20T15:09:11 < Laurenceb> after line 135 is called
2015-02-20T15:09:30 < jpa-> yeah, line 125 if retriggering even though TXE interrupt is disabled could explain it
2015-02-20T15:09:38 < Laurenceb> gunna try with the lines reordered
2015-02-20T15:09:48 < jpa-> i would just add extra check on line 125
2015-02-20T15:09:59 < Laurenceb> yeah
2015-02-20T15:09:59 < jpa-> i.e. don't transmit stuff if the next thing you want is re-start
2015-02-20T15:10:11 < Laurenceb> would also explain why its glitchy and clock dependent
2015-02-20T15:10:14 < Laurenceb> yeah
2015-02-20T15:12:22 < zyp> I don't have separate branches for TXE and BTF in my code, I just handle TXE=1 && BTF=0
2015-02-20T15:13:03 < zyp> but at this point I'm not sure if my code even works better than yours, I haven't touched it in years :p
2015-02-20T15:13:28 < jpa-> i only set semaphore in my i2c interrupt and do everything in thread
2015-02-20T15:13:53 < jpa-> (but i'm using DMA for the main transfer)
2015-02-20T15:13:56 < zyp> that sounds like a bad idea
2015-02-20T15:14:13 < zyp> isn't there an errata that the i2c can fuck up if you don't service it fast enough?
2015-02-20T15:14:13 < jpa-> why?
2015-02-20T15:14:24 < Laurenceb> buffer... stuff
2015-02-20T15:14:32 < jpa-> nope, if you don't clear the SR bits too early
2015-02-20T15:14:33 < Laurenceb> im using "Method 2"
2015-02-20T15:14:42 < zyp> so the errata sheet recommends handling it with a high priority interrupt
2015-02-20T15:14:43 < Laurenceb> but even Method 2 fails if you are too slow
2015-02-20T15:14:48 < Laurenceb> thats why its hard to debug
2015-02-20T15:15:00 < jpa-> zyp: yes, after "method 1: just use dma"
2015-02-20T15:15:02 < Laurenceb> im using a scope atm and not setting breakpoints
2015-02-20T15:15:22 < zyp> Laurenceb, you should do some trace logging
2015-02-20T15:15:30 < Laurenceb> ooh good point
2015-02-20T15:15:37 < Laurenceb> this is a perfect application for it

2015-02-20T15:48:00 < PaulFertser> _Sync_: SWO (and other trace support) is WiP in OpenOCD, you can try it if you grab the branch from Gerrit.
2015-02-20T15:48:36 < _Sync_> because that shit looks cool
2015-02-20T15:49:50 < Laurenceb> there are 3 PLLs
2015-02-20T15:49:57 < jpa-> WiP in sigrok also, but you can't try it yet ;)
2015-02-20T15:50:08 < Laurenceb> could be useful
2015-02-20T15:51:00 < jpa-> _Sync_: there are three trace subsystems in stm32: ITM gives info from software, pretty much like printf would; DWT gives info about IRQs and can periodically give PC value; ETM gives instruction-level tracing but slows down the CPU
2015-02-20T15:51:34 < jpa-> there are quite many tools for ITM and DWT tracing already, but not good documentation

2015-02-20T16:02:32 < dongs> other than mounting holes
2015-02-20T16:02:44 < dongs> 'expansion value from rules'
2015-02-20T16:02:46 < PaulFertser> With ITM you have many different channels that you can print to, and demultiplex on host.
2015-02-20T16:03:05 < dongs> 4 mil?
2015-02-20T16:03:06 < dongs> is that huge?
2015-02-20T16:03:42 < PaulFertser> Also, you can leave tracing code in production builds, it doesn't require a debugger to be attached (as is the case for semihosting).

2015-02-20T16:05:57 < dongs> yeah
2015-02-20T16:06:00 < zyp> traces entering the pads will affect the unmasked area a fair bit

2015-02-20T16:07:36 < dongs> i thnk mine are ev en wider
2015-02-20T16:07:40 < dongs> less mask spacing than your shit
2015-02-20T16:07:56 < zyp> true, that's not the problem
2015-02-20T16:08:55 < zyp> I'm just concerned that differences in unmasked area will lead to uneven soldering on the pads
2015-02-20T16:09:29 < zyp> considering other qfn bullshit I've had before
2015-02-20T16:09:30 < dongs> is that a recommended footprint
2015-02-20T16:09:39 < zyp> yes, strait from datasheet
2015-02-20T16:09:45 < zyp> and yes, I think it looks dumb
2015-02-20T16:09:50 < dongs> i usually just use the ipc generator thingy
2015-02-20T16:09:58 < dongs> and clean it up and/or if datasheet has a footprint just copy from there
2015-02-20T16:10:06 < dongs> but i never change/edit mask stuff just let it default
2015-02-20T16:10:31 < zyp> I'm considering extending the pads a bit, like your footprint
2015-02-20T16:11:34 < dongs> is silk centered around apckage?
2015-02-20T16:11:39 < dongs> centerline of silk
2015-02-20T16:11:41 < zyp> yes
2015-02-20T16:13:09 < zyp> http://bin.jvnv.net/f/g17eb.JPG <- I remember on this board, the QFN in the corner had problems on two out of three boards, while the QFN in the middle was perfect on all three
2015-02-20T16:13:41 < dongs> legs look longer
2015-02-20T16:13:45 < dongs> anyway,t i doubt it was mask issue
2015-02-20T16:14:22 < dongs> probly just shitty designed pads ;p
2015-02-20T16:14:27 < zyp> longer pads means that the area differences due to traces from the edges are smaller
2015-02-20T16:14:27 < dongs> try makign a qfn24 or wahtever that is
2015-02-20T16:14:29 < dongs> in ipc footprint thing
2015-02-20T16:14:40 < dongs> and compare and see which one is better looking
2015-02-20T16:14:52 < zyp> yeah
2015-02-20T16:15:38 < dongs> I have 3 QFN24s in my lib and all are same except different size EP
2015-02-20T16:15:44 < dongs> but outer pads dimension stays same
2015-02-20T16:15:57 < dongs> only inner part gets shorter/longer to match EP size
2015-02-20T16:16:49 < dongs> but all my pads stick out at least 0.2mm
2015-02-20T16:16:52 < dongs> from outside
2015-02-20T16:17:07 < zyp> oh, IPC footprint wizard is different from other footprint wizard
2015-02-20T16:17:11 < dongs> from pad edge to silk centerline
2015-02-20T16:17:12 < dongs> yes
2015-02-20T16:17:18 < dongs> other one is kinda ghetto
2015-02-20T16:17:19 < zyp> this shit looks much saner
2015-02-20T16:17:27 < zyp> yeah, that's why I don't use it
2015-02-20T16:18:16 < dongs> id uno why the fuck they keep both

2015-02-20T18:50:42 < jpa-> hmm, cortex-m ETM does not support data tracing
2015-02-20T18:50:47 < jpa-> well, less packets for me to decode
2015-02-20T18:52:53 < karlp> jpa-: I didn't think ETM slowed down the target at all? I thought that was the whole point?
2015-02-20T18:54:19 < PaulFertser> karlp: ETM has two modes: dropping extra info and slowing down. It seems that only one of that is usually implemented.
2015-02-20T18:55:05 < PaulFertser> If TPIU is configured in a mode too slow to pass all the trace data, either dropping or stalling should happen.
2015-02-20T18:55:31 < jpa-> nah, both are implemented
2015-02-20T18:55:33 < Laurenceb> http://regmedia.co.uk/2015/02/18/top_gear_women_by_steve_caplin_1a.jpg
2015-02-20T18:56:03 < jpa-> but ETM with dropped data feels like it has somewhat limited usefulness
2015-02-20T18:56:31 < jpa-> because when outputting through TRACESWO, it will be dropping over 50% of samples
2015-02-20T18:57:50 < zyp> as long as it gives you enough data points to follow the general flow…
2015-02-20T18:58:09 < jpa-> maybe yeah, but you can follow general flow with DWT periodic PC sampling also
2015-02-20T18:58:23 < jpa-> and if you have DWT periodic PC sampling + exception trace, atleast you'll see all interrupts

2015-02-20T19:03:58 < karlp> well, yeah, etm over swo is going to be limited,
2015-02-20T19:04:12 < karlp> that's what those extra pins are for ;)
2015-02-20T19:04:25 < karlp> your sigrok etm looked cool though
2015-02-20T19:04:48 < jpa-> hmm, dwt can still do data tracing for watchpoints
2015-02-20T19:05:01 < jpa-> overall seems like dwt/itm will be more useful on cortex-m than etm

2015-02-20T19:29:22 < Steffanx> The SWO will slow down the cpu when you have more interrupts/s than the swo can output, not?
2015-02-20T19:30:25 < Simon--> Laurenceb: that's probably unique to me. gcc uses r1 or something. I just use it so I can also share Z (16-bit) as an ISR vector to save cycles
2015-02-20T19:31:00 < Steffanx> when using for example a uart style of 1Mbit/s, exception tracing and a shitload of interrupts

2015-02-20T19:32:06 < kakeman> oh just remembered I should add uart leads to my debug harness
2015-02-20T19:32:13 < Laurenceb> ive been using a fork of your esc code for rpm feedback
2015-02-20T19:33:47 < Laurenceb> this fork
2015-02-20T19:33:48 < Laurenceb> https://github.com/balrog-kun/tgy
2015-02-20T19:34:11 < Laurenceb> i had to turn off voltage and temperature monitoring whilst the motor is running - caused commutation glitches
2015-02-20T19:36:49 < gxti> Steffanx: at 1mbit/s you should probably use dma anyway, not per-byte interrupts
2015-02-20T19:36:55 < Laurenceb> itd be nice if there was a simple i2c protocol in the main branch :P
2015-02-20T19:38:12 < gxti> just heuristically speaking if you have enough interrupts to saturate a trace output then you have too many interrupts, period
2015-02-20T19:43:56 < karlp> Steffanx: no, itm just overflows, I haven't seen anything in itm/dwt about stalling the procesor, htough paul and jpa say that ETM can stall the processor if you configure it like that.
2015-02-20T19:44:46 < karlp> gxti: I think he meant that he was writing to ITM at 1Mbit, not byte by byte uart...
2015-02-20T19:45:06 < gxti> oic
2015-02-20T19:45:12 < gxti> still true though
2015-02-20T19:46:16 < Steffanx> i meant swo/itm using 1mbit uart style formatting.
2015-02-20T19:51:06 < Steffanx> so overflow it is.
2015-02-20T19:52:32 < Steffanx> should ask better questions next time, and not using examples.
2015-02-20T19:58:16 < jpa-> yeah, DWT/ITM overflows (but atleast it generates an overflow packet to inform you)
2015-02-20T19:58:25 < Steffanx> ah ok
2015-02-20T19:59:00 < jpa-> but the uart style write functions of course have the while loop to wait until data is transmitted
2015-02-20T20:00:12 < karlp> if you're writing blocks of data, yeah,
2015-02-20T20:00:30 < karlp> but that's a potential cpu overhead, you should be somewhat careful with that ;)
2015-02-20T20:00:48 < karlp> or, write values instead of using it with printf....
2015-02-20T20:01:29 < jpa-> yeah, it's nice that you can write 32 bit values directly
2015-02-20T20:01:41 < jpa-> i decode 8 bit writes to text and rest to hex numbers
2015-02-20T20:02:08 < gxti> i really need to learn how to trace like a pro, someday

2015-02-20T20:13:51 < gxti> tried busblaster (ft2232 based) and f4discovery's stlink

2015-02-20T20:14:37 < gxti> f4disco worked well enough to flash things but not debug
2015-02-20T20:15:30 < gxti> bus blaster was probably just a poor purchase, should have gotten a jlink ripoff
2015-02-20T20:15:38 < qyx_> interesting, i had only one single issue with erasing on F4 target
2015-02-20T20:15:57 < qyx_> everything worked just fine
2015-02-20T20:16:10 < qyx_> althoguh i don't use debugging features much
2015-02-20T20:16:13 < gxti> didn't know what i was doing when i bought it, and openocd with swd wasn't even released yet
2015-02-20T20:16:42 < gxti> so maybe i just buy something more popular and it magically "works for me" too

2015-02-20T20:17:06 < gxti> i haven't really been too eager to switch since BMP does all the debugging i need, even if it is a little quirky it's nice to not need any host software at all other than gdb
2015-02-20T20:17:06 < qyx_> and yes, oocd didn't work for me with swd/ft232h or whatever it was
2015-02-20T20:17:46 < qyx_> i also wanted bmp
2015-02-20T20:17:53 < qyx_> but stlinks are just fine
2015-02-20T20:18:24 < Steffanx> ii tried the swo stuff of hte bmp, but "couldnt make it work(tm)"
2015-02-20T20:18:26 < gxti> i could get a stlink ripoff (i don't want to use my f4disco all the time) but i kind of want a semi-good adapter that can do regular jtag stuff
2015-02-20T20:18:50 < gxti> not sure what meets that criteria
2015-02-20T20:18:52 < jpa-> qyx_: f4 discovery is popular and nowadays its stlinkv2 works very well with openocd
2015-02-20T20:19:06 < qyx_> jpa-: yep
2015-02-20T20:19:16 < qyx_> i use L1 disco as a programmer
2015-02-20T20:19:33 < jpa-> actually meant that message to gxti 
2015-02-20T20:19:49 < gxti> oh, and i need to be able to plug my tagconnect into it although i can always make an adapter
2015-02-20T20:19:49 < jpa-> a year back i still had occassional issues with it, so may be worth to try newest openocd

2015-02-20T21:23:13 < PaulFertser> ft2232h is the best cheap SWO adapter actually, it captures on 12MHz all right.
2015-02-20T21:23:29 < gxti> what's the best overall?
2015-02-20T21:25:09 < PaulFertser> Among cheap stuff, ft2232h is the fastest. stlink just works. jlink will work with a new driver (not yet published by its author). Atmel's CMSIS-DAP (EDBG) will likely work once i get the boards.

2015-02-21T04:01:31 < dongs> so stoned
2015-02-21T04:02:33 < emeb_mac> start innovatin'
2015-02-21T04:05:56 < dongs> i need to drag out my modulator+attenuator shit
2015-02-21T04:05:58 < dongs> to test this new thing
2015-02-21T04:06:16 < dongs> under same over the air reception, old shit demod C/N is like 25dB, new shit is ~40
2015-02-21T04:06:22 < dongs> same demod, only changed tuner
2015-02-21T04:07:21 < dongs> seems its too good
2015-02-21T04:11:48 < emeb_mac> just 15 dB
2015-02-21T04:11:49 < emeb_mac> but that's a lot
2015-02-21T04:11:54 < emeb_mac> this with the R820T
2015-02-21T04:12:02 < emeb_mac> ?
2015-02-21T04:12:11 < dongs> yes
2015-02-21T04:12:11 < dongs> vs mxl603
2015-02-21T04:13:31 < emeb_mac> hmm - no datasheets. all proprietary I guess
2015-02-21T04:14:00 < emeb_mac> sux how all that cable/satellite stuff is NDA only
2015-02-21T04:14:30 < dongs> theres not even a proper datasheet from vendor
2015-02-21T04:14:31 < dongs> lulz
2015-02-21T04:14:48 < emeb_mac> heh
2015-02-21T04:15:01 < emeb_mac> someone put the R820 stuff out a few years ago
2015-02-21T04:15:14 < emeb_mac> got it squirreled away somewhere
2015-02-21T04:15:25 < dongs> ya its stil lsame one
2015-02-21T04:15:29 < dongs> 820T2 is out (what im using now)
2015-02-21T04:15:39 < dongs> pin/etc compatible
2015-02-21T04:16:00 < dongs> my modulator box keeps crashing if I click things too fast
2015-02-21T04:16:10 < emeb_mac> high quality!
2015-02-21T04:16:20 < dongs> windows xp PROFESSIONAL
2015-02-21T04:16:34 < dongs> i connect by RDP tho so i cant tell what teh fuck is up it just freezes
2015-02-21T04:16:34 < emeb_mac> emphasis yours
2015-02-21T04:17:12 < emeb_mac> R820 is I2C right?
2015-02-21T04:17:18 < dongs> ya
2015-02-21T04:17:29 < dongs> the only non-i2c tuner i ever seen was that mirics shit
2015-02-21T04:17:43 < emeb_mac> oh ya - remember that
2015-02-21T04:17:55 < emeb_mac> I guess Realtek ate their lunch
2015-02-21T04:18:06 -!- Vutral [~ss@mirbsd/special/Vutral] has joined ##stm32
2015-02-21T04:18:36 < dongs> WTF
2015-02-21T04:18:37 < dongs> it froze again
2015-02-21T04:18:46 < emeb_mac> blame it on Bill Gates
2015-02-21T04:19:29 < emeb_mac> what MCU you driving that with?
2015-02-21T04:19:52 < dongs> none, just a usb bridge
2015-02-21T04:20:16 < dongs> but i have stuff with mlx603 and stm32 on it
2015-02-21T04:20:21 < emeb_mac> ah
2015-02-21T04:29:13 < emeb_mac> got one of these signal gens yesterday: http://www.siglent.eu/sdg1025-25mhz.html
2015-02-21T04:29:50 < emeb_mac> has lots of waveforms, modulations & 2 chl output. UI is kinda slow going tho
2015-02-21T04:30:13 < dongs> -70dBm still full signal
2015-02-21T04:30:20 < emeb_mac> wow
2015-02-21T04:30:21 < dongs> er no errors
2015-02-21T04:30:28 < dongs> 64qam 3/4
2015-02-21T04:30:32 < dongs> 20dB C/N
2015-02-21T04:30:42 < dongs> wait make that -75
2015-02-21T04:30:44 < emeb_mac> what's normal?
2015-02-21T04:30:55 < dongs> damn this thing is a beast
2015-02-21T04:31:05 < dongs> mxl would shit itself below 65
2015-02-21T04:31:12 < emeb_mac> must have a good front end LNA
2015-02-21T04:31:35 < emeb_mac> wonder what the OOB rejection is tho
2015-02-21T04:32:02 < emeb_mac> my experience with those R820 based dongles is that they're pretty susceptible to interference
2015-02-21T04:35:41 < dongs> ah, -80 was 16QAM, used wrong source file. 64QAM gets occasional error that passes through error correction
2015-02-21T04:35:51 < dongs> -78 for QAM64 is solid
2015-02-21T04:37:07 < emeb_mac> this terrestrial or satellite?
2015-02-21T04:37:14 < dongs> terrestrial
2015-02-21T04:37:23 < dongs> satellite doesnt use qam
2015-02-21T04:37:29 < emeb_mac> so that would straight to an antenna
2015-02-21T04:37:50 < dongs> i got a garbage cable going from attenuator to receiver
2015-02-21T04:38:11 < dongs> mxl would report 2 dB less on input power than what attenuator said, so maybe cable drops a couple dB too
2015-02-21T04:38:22 < emeb_mac> huh. satellite modems I worked on did up to 256QAM
2015-02-21T04:38:25 < dongs> R820 doesnt have input level meter tho :(
2015-02-21T04:38:37 < emeb_mac> proprietary tho
2015-02-21T04:38:38 < dongs> for what, downlink?
2015-02-21T04:38:42 < emeb_mac> yup
2015-02-21T04:38:45 < dongs> odd
2015-02-21T04:38:53 < emeb_mac> well - special purpose
2015-02-21T04:39:01 < dongs> as far as I know all public satellite internet stuff in kuband is just regular dvb-s or s2 with qpsk or 8psk
2015-02-21T04:39:15 < emeb_mac> ya - that's public stuff
2015-02-21T04:39:24 < dongs> plebs
2015-02-21T04:39:27 < emeb_mac> heh
2015-02-21T04:39:33 < dongs> how can i exactly find out how much my cable is dropping?
2015-02-21T04:39:45 < dongs> stick on spectrum analyzer and see peak?
2015-02-21T04:39:48 < emeb_mac> network analyzer :P
2015-02-21T04:40:16 < emeb_mac> but for simple attenuation use generator -> cable -> spectrum analyzer
2015-02-21T04:40:21 < emeb_mac> w/ and w/o cable
2015-02-21T04:40:32 < emeb_mac> and use max hold to see difference
2015-02-21T04:40:53 < emeb_mac> what freq?
2015-02-21T04:40:58 < dongs> well it can be a ny
2015-02-21T04:41:02 < dongs> but im doing 539.143mhz
2015-02-21T04:41:11 < emeb_mac> UHF stuff...
2015-02-21T04:41:13 < dongs> im just using regular crap coax
2015-02-21T04:41:16 < emeb_mac> shouldn't be too bad
2015-02-21T04:43:23 < dongs> heh shit is barely visible on analyzer
2015-02-21T04:43:24 < jadew> dongs, RG58?
2015-02-21T04:43:38 < dongs> jadew: no clue, just trash(tm)
2015-02-21T04:43:39 < emeb_mac> broad spectrum?
2015-02-21T04:43:54 < dongs> 3C-2V 75 ohm coaxial cable
2015-02-21T04:44:00 < dongs> emeb_mac: no centered at 539.143 w/8mhz width
2015-02-21T04:44:12 < emeb_mac> weird
2015-02-21T04:44:16 < jadew> dongs, it's a gamble with those, so if you're only interested in that particular cable, you can measure it specifically, but you can't generalise
2015-02-21T04:44:20 < jadew> they have very loose specs
2015-02-21T04:44:20 < emeb_mac> shouldn't be too far down
2015-02-21T04:44:55 < dongs> i can see it, its just junk
2015-02-21T04:45:16 < emeb_mac> average over 100 sweeps...
2015-02-21T04:45:55 < dongs> jadew: how to measure
2015-02-21T04:45:58 < jadew> to find out how much it's dropping at a particular frequency, just put in a signal at that frequency, directly into the SA, hold the trace and then put the cable between the cable you used to feed the SA and the SA
2015-02-21T04:46:06 < dongs> http://i.imgur.com/09xAIc2.png
2015-02-21T04:46:14 < dongs> jadew: yeah, i suspected that was going to be teh answer
2015-02-21T04:46:22 < dongs> how the fuck im gonna connect signal generator to it directly? :)
2015-02-21T04:46:31 < jadew> dongs, another cable
2015-02-21T04:46:47 < emeb_mac> heh
2015-02-21T04:46:49 < jadew> it doesn't matter how much that one drops, because you're only interested in the relatvie measurement
2015-02-21T04:47:01 < emeb_mac> since that's in both measurements it washes out
2015-02-21T04:47:04 < jadew> so if you use sig gen -> cable A -> SA
2015-02-21T04:47:14 < jadew> and then sig gen -> cable A -> test cable -> SA
2015-02-21T04:47:24 < jadew> you'll see the exact drop of the test cable
2015-02-21T04:47:25 < dongs> oh, like that
2015-02-21T04:50:02 < jadew> also, keep in mind that you'll have some drop due to the impedance mismatch too
2015-02-21T04:50:16 < dongs> yeah
2015-02-21T04:50:16 < jadew> your cable is 75 Ohm and your SA is 50
2015-02-21T04:50:19 < dongs> modulator is 50ohm
2015-02-21T04:50:20 < dongs> yes
2015-02-21T04:50:28 < dongs> and so is sa
2015-02-21T04:50:34 < jadew> yeah, was going to say that the sig gen might be 50 too
2015-02-21T04:50:42 < jadew> so you get a lot of reflection on both ends
2015-02-21T04:52:05 < emeb_mac> 50 / 75 ohm mismatch loses less than 1dB
2015-02-21T04:53:01 < englishman> or 4% powahhh
2015-02-21T04:53:39 < englishman> but thats at each discontinuity right
2015-02-21T04:53:45 < emeb_mac> yup
2015-02-21T04:53:56 < emeb_mac> it's about 0.35dB each
2015-02-21T04:54:33 < englishman> so 7.9% power loss ignoring other reflections
2015-02-21T04:55:01 < dongs> need chatch pro advice
2015-02-21T04:55:01 < englishman> dongs didnt you buy some rg316 a while back
2015-02-21T04:55:11 < dongs> not that I know of
2015-02-21T04:55:18 < dongs> i just have garbage cables all over
2015-02-21T04:55:26 < englishman> you gotta have some 50 ohm bnc shit somewhere
2015-02-21T04:56:14 < dongs> ya i dont, i solved the problem by buying a shitload of F>BNC adapters
2015-02-21T04:56:20 < dongs> i shoulfd really pro up and get some bnc shit yea
2015-02-21T04:56:47 < englishman> you got that big spendy mdo and no cablez
2015-02-21T04:56:59 < englishman> very unpro
2015-02-21T04:58:34 < dongs> guilty as charged
2015-02-21T04:59:45 < dongs> i cant even find my "good" F-conector cable
2015-02-21T05:00:00 < jadew> dongs, in that screenshot, your signal is there?
2015-02-21T05:00:05 < dongs> yes
2015-02-21T05:00:08 < jadew> lol
2015-02-21T05:00:15 < dongs> its attenuated -80dB at modulator tho
2015-02-21T05:00:20 < jadew> ah!
2015-02-21T05:00:22 < jadew> ok then hehe
2015-02-21T05:01:18 < jadew> looks like there's something several MHz each side too
2015-02-21T05:01:33 < jadew> it doesn't seem to be confined in the section between the markers
2015-02-21T05:01:54 < emeb_mac> should be about 6MHz wide no?
2015-02-21T05:02:58 < jadew> what's at 539 MHz anyway?
2015-02-21T05:03:01 < jadew> TV?
2015-02-21T05:05:25 < jadew> channel 29 it seems
2015-02-21T05:22:54 < emeb_mac> "Dubai Marina Torch" in flames. Oh the irony.
2015-02-21T05:44:48 < zyp> supercap specs kinda sounds like shit
2015-02-21T05:45:14 < zyp> they list stuff like «lifetime: 1000 hours at 70°C»
2015-02-21T05:45:38 < dongs> markers are just junk
2015-02-21T05:45:49 < dongs> it is 6mhz wide, with center at 539.143
2015-02-21T05:46:11 < zyp> and then you can apparently expect it to be doubled for every 10°C below that
2015-02-21T05:46:24 < zyp> which still kinda sounds like shit though
2015-02-21T05:48:09 < emeb_mac> whats the supercap for?
2015-02-21T05:48:49 < zyp> vbat
2015-02-21T05:48:58 < zyp> i.e. rtc
2015-02-21T05:49:47 < dongs> i hope youre not planning on exploding my reflow oven
2015-02-21T05:50:27 < zyp> stuff syncs over SNTP, but it's preferable to have correct time between powerup and first sync
2015-02-21T05:52:15 < zyp> I ran the numbers earlier today, and a 200mF supercap should be enough to power vbat for a week
2015-02-21T05:52:49 < emeb_mac> wow
2015-02-21T05:53:12 < emeb_mac> I just put a batt connector on my board
2015-02-21T05:53:44 < zyp> it's not that big of a deal
2015-02-21T05:54:20 < zyp> normally network should be available, so it should sync soon after powerup anyway
2015-02-21T05:57:02 < zyp> hmm
2015-02-21T05:57:22 < zyp> dongs, you should probably check availability of supercaps as well
2015-02-21T05:58:39 < zyp> digikey has a lot of stuff, but most of what looks suitable is of course out of stock :p
2015-02-21T06:03:30 < emeb_mac> typical
2015-02-21T06:05:09 < zyp> http://media.digikey.com/photos/Panasonic%20Photos/EN%20SERIES%20TYPE%20RL%201.8H,6.8D.jpg <- this sort of footprint looks fairly common among multiple vendors
2015-02-21T06:05:27 < upgrdman> other than price, what is the drawback of a supercap? high esr?
2015-02-21T06:05:43 < zyp> I remember the broken supercaps I replaced once was in that sort of package
2015-02-21T06:05:46 < emeb_mac> very - I think I measured > 1K for some
2015-02-21T06:06:10 < zyp> upgrdman, ESR is in the orders of hundreds to thousands
2015-02-21T06:06:18 < zyp> and the lifetime is limited
2015-02-21T06:06:33 < emeb_mac> can they stand the temps in a reflow cycle?
2015-02-21T06:06:37 < zyp> yes
2015-02-21T06:06:41 < dongs> zyp, ive seen thoes yeah
2015-02-21T06:06:46 < upgrdman> lifetime since manuf, or time while charged?
2015-02-21T06:07:03 < zyp> upgrdman, a bit of either
2015-02-21T06:07:05 < upgrdman> k
2015-02-21T06:07:38 < zyp> lifetime is limited either way, being charged seems to decrease it further
2015-02-21T06:09:39 < upgrdman> use this for Vbatt   http://www.mouser.com/ProductDetail/Nichicon/JJD0E408MDEFBN/?qs=sGAEpiMZZMsCu9HefNWqpmqQE3GPPpj%252b4%252b6%252bq2NlK0s%3d

2015-02-21T06:11:01 < upgrdman> :)
2015-02-21T06:11:14 < zyp> a bit less if you turn off backup sram
2015-02-21T06:11:30 < zyp> (or don't turn it on in the first place, probably)
2015-02-21T06:11:59 < upgrdman> dat 2.2mOhm ESR

2015-02-21T06:22:40 < stephendwyer> zyp: be happy you have such a low draw - we are using a 1F supercap and only get less than 48hrs backup... :(
2015-02-21T06:22:53 < zyp> for what?
2015-02-21T06:22:55 < stephendwyer> F1 + cell module vbat
2015-02-21T06:23:03 < stephendwyer> plus leakage...
2015-02-21T06:33:32 < PeterM> may as well use arechargeable li2032
2015-02-21T06:39:22 < stephendwyer> ya, turns out the backup won't be used very often or critically anyways, otherwise we would have

2015-02-21T08:20:32 < emeb_mac> what level of qam?
2015-02-21T08:21:07 < dongs> 64
2015-02-21T08:21:17 < dongs> yeah, it starts to have post-BER at -76
2015-02-21T08:22:42 < dongs> well, this will more than do
2015-02-21T08:24:03 < emeb_mac> sounds pretty good
2015-02-21T08:24:29 < dongs> hm, mxl input power is telling me when i'm at -70, its seeing -74.5
2015-02-21T08:25:37 < dongs> i gotta figure out how much this cable really drops
2015-02-21T08:25:39 < emeb_mac> so maybe it's not that much better than the old design.
2015-02-21T08:26:13 < dongs> yeah but mxl never has C/N above 25-ish
2015-02-21T08:26:52 < dongs> if lets say cable really drops 4dB, that means my new shit is still receiving at -83dBm actual
2015-02-21T08:27:15 < dongs> mxl is shitting itself at -72-ish
2015-02-21T08:27:42 < emeb_mac> 11dB - pretty good

2015-02-21T16:02:05 < dongs> looks like usb to 8bit fifo?
2015-02-21T16:02:10 < Lux> looks like a new version
2015-02-21T16:02:27 < Lux> the one we have in our hackerspace still has dip components
2015-02-21T16:02:47 < Lux> does it also come with moshi draw ? :)
2015-02-21T16:03:50 < dongs> i think so
2015-02-21T16:07:27 < dongs> this is the color i wanna make pcb in
2015-02-21T16:08:55 < PeterM> what? the shit yellow?
2015-02-21T16:08:59 < dongs> yes
2015-02-21T16:09:40 < PeterM> nah get it pink http://sakuraboard.net/full_no.jpg

2015-02-21T16:11:09 < dongs> that was very expensive.

2015-02-21T16:14:38 < dongs> or hardware
2015-02-21T16:15:19 < Lux> hardware should probably be fine
2015-02-21T16:15:29 -!- Viper168_ is now known as Viper168
2015-02-21T16:15:30 < Lux> the software is just pretty counter intuitive
2015-02-21T16:16:24 < karlp> dongs, ch341 can do usb2uart,usb2i2c, usb2epp usb2"mem" usb2irda sort of things
2015-02-21T16:16:30 < Lux> and i think it only accepts image files
2015-02-21T16:17:29 < karlp> haven't seen in person it ever used in any of the printer/mem modes though, but I'msure it's ou tthere
2015-02-21T16:18:55 < dongs> usb2epp, it will actually come up as printer class or whatever?
2015-02-21T16:19:24 < PeterM> nah will appear as a parallolport
2015-02-21T16:20:58 < rbino> hi everybody, anyone doing STM32 development on GNU/Linux with free (as in freedom) tools? any tips on getting started?
2015-02-21T16:21:33 < dongs> install stm32cubemx
2015-02-21T16:21:37 < PeterM> go to a hospital, get your sores checked and sutured closed
2015-02-21T16:22:37 < rbino> dongs, I will try it, thanks
2015-02-21T16:23:14 < rbino> I made the obligatory blinking LED but when I tried to use the Cube library things started to get messy
2015-02-21T16:23:24 < jpa-> rbino: don't use cube, try chibios
2015-02-21T16:23:44 < jpa-> and openocd for debugging

2015-02-21T16:24:21 < karlp> dongs: maybe? havent' got any hardware doign that, but the datasheet suggests it will: https://github.com/commandtab/ch341eeprom/blob/master/ch341docs/CH341DS1.PDF
2015-02-21T16:25:08 < rbino> jpa-, I wanted to try using it with the STM libraries since it could be useful if I have to use them for work
2015-02-21T16:25:18 < dongs> cool
2015-02-21T16:25:40 < karlp> dongs: if you can use your sources to get any actual usb protocol docs it would be radical.
2015-02-21T16:25:47 < rbino> if I have to use a RTOS, I use Miosix http://miosix.org/
2015-02-21T16:25:52 < jpa-> rbino: oh well, sure, if you really want to; but overall i would recommend against using the cube or stdperiph wrapper functions for anything
2015-02-21T16:26:15 < jpa-> rbino: plain register access (stm32fxxx.h) is better than cube IMO
2015-02-21T16:26:44 < jpa-> rbino: nice thing about chibios is the reasonable HAL for STM32
2015-02-21T16:27:22 < rbino> with Miosix I succeeded in writing an open source driver for the microphone on the STM32F4 Discovery
2015-02-21T16:27:40 < rbino> anyway jpa-, I guess I will try with raw access to the registers
2015-02-21T16:28:18 < Lux> rbino: there is also http://www.libopencm3.org/wiki/Main_Page
2015-02-21T16:28:32 < dongs> lux, when he said "work" he probably meant "evil closed sores"
2015-02-21T16:28:38 < dongs> so all this freetard shit doesnt apply automatically
2015-02-21T16:28:53 < rbino> dongs, exactly
2015-02-21T16:29:14 < dongs> ohhhh
2015-02-21T16:29:15 < dongs> mxgui
2015-02-21T16:29:16 < Lux> kay :P
2015-02-21T16:29:19 < dongs> tectu has competition
2015-02-21T16:29:29 < Lux> wasn't the question freetard tools ?
2015-02-21T16:29:47 < dongs> you can still use freetard tools to make closed sores shit
2015-02-21T16:29:50 < dongs> it just sucks much more
2015-02-21T16:29:51 < rbino> Lux, the fact is, I sometimes work on firmware devvvelopment
2015-02-21T16:30:07 < rbino> on STM32
2015-02-21T16:30:42 < Lux> buy keil
2015-02-21T16:31:10 < rbino> at work I have to use what they provide me (it varies depending on the client, I tried Keil, Crossworks and maybe some other)
2015-02-21T16:32:05 < rbino> the thing I wanted was a free tool which I could use on my machine to "exercise" using the STM32 with the STM libraries
2015-02-21T16:32:15 < rbino> I don't know if such thing exist
2015-02-21T16:32:38 < jpa-> stdperiph does work just fine with gcc, just that very few people want to voluntarily use it
2015-02-21T16:32:56 < Lux> if you are looking for an ide, maybe cocoox ?
2015-02-21T16:33:03 < Lux> never really liked it
2015-02-21T16:33:45 < Lux> in fact st should be coming out with their own shit soon
2015-02-21T16:33:47 < rbino> jpa-, I think this is because it's a mess manually writing Makefiles (or maybe it's me, I stayed up untile 5 AM this night to try making it work)
2015-02-21T16:34:24 < jpa-> rbino: nah, no need to write the makefiles manually if you don't want to
2015-02-21T16:34:34 < jpa-> CSRC = foobar/*.c  etc. works just fine
2015-02-21T16:35:06 < rbino> tried that to no avail
2015-02-21T16:35:07 < jpa-> the reason why i avoid stdperiph is that understanding the raw registers is much easier than trying to understand stdperiph, and 90% of the functions there are just useless overhead
2015-02-21T16:35:13 < rbino> but maybe it's Cube's fault
2015-02-21T16:35:20 < rbino> I will try with the raw registers
2015-02-21T16:35:25 < jpa-> nah, makefiles aren't always easy
2015-02-21T16:35:54 < jpa-> can't see how it would be cube's fault, and if it is you can probably find out how it is at fault and work around it
2015-02-21T16:36:47 < rbino> the problem is, I have a blinking led
2015-02-21T16:37:02 < rbino> made with raw register access
2015-02-21T16:37:08 < rbino> the moment I call HAL_Init()
2015-02-21T16:37:12 < rbino> the LED is gone
2015-02-21T16:37:24 < jpa-> sure, because it reinits the peripherals?
2015-02-21T16:37:38 < jpa-> if it crashes after that, use gdb to find out where
2015-02-21T16:37:42 < qyx_> what, imgur
2015-02-21T16:38:00 < rbino> will try that, this night I ragequitted at 5
2015-02-21T16:38:47 < rbino> so jpa- you suggest using raw registers and writing my own functions to use them instead of using Cube?
2015-02-21T16:39:14 < qyx_> dongs: works for me
2015-02-21T16:39:44 < jpa-> rbino: yep
2015-02-21T16:40:53 < rbino> anyway I will try also the other things you linked me like ChibiOS
2015-02-21T16:41:08 < jpa-> yeah, better to know many options
2015-02-21T16:41:30 < jpa-> and i guess cube is not as horrible as stdperiph, i haven't used cube much
2015-02-21T16:42:00 < rbino> yeah, the "pure STM" approach will be mainly an exercise for work, if I have to quickly develop something for myself better have a little bit of infrastructure
2015-02-21T16:42:36 < jpa-> also it will be very useful for debugging, no matter what kind of library is running
2015-02-21T16:43:04 -!- KreAture_Zzz is now known as KreAture_
2015-02-21T16:43:29 < qyx_> that mxgui
2015-02-21T16:43:31 < qyx_> Tectu: ^
2015-02-21T16:43:38 < qyx_> you can steal some ideas
2015-02-21T16:43:43 < rbino> yeah, also Miosix uses openocd for debugging
2015-02-21T16:44:01 < jpa-> qyx_: which ideas are you thinking about?
2015-02-21T16:44:17 < jpa-> i didn't see anything very innovative in mxgui
2015-02-21T16:44:26 < Tectu> qyx_, what jpa- said ^
2015-02-21T16:44:36 < qyx_> nah, then nothing was said
2015-02-21T16:44:50 < jpa-> maybe steal their license
2015-02-21T16:44:59 < qyx_> i am trying to figure out if that miosix is awesome in some way
2015-02-21T16:45:08 < Tectu> qyx_, are you random bitching around trying to offend people and starting flamewars without even reading what you're talking about nor at least comparing specs and features?
2015-02-21T16:45:19 < qyx_> Tectu: no
2015-02-21T16:45:24 < jpa-> Tectu: nah, he was just happy to see a new library
2015-02-21T16:45:30 < jpa-> i had never heard about miosix either
2015-02-21T16:45:32 < qyx_> i just read "thread safety"
2015-02-21T16:45:35 < qyx_> me too
2015-02-21T16:45:41 < qyx_> i see itfor the first time now
2015-02-21T16:45:43 < Tectu> ugfx has that too
2015-02-21T16:45:48 < qyx_> then \o/
2015-02-21T16:46:02 < Tectu> ;-)
2015-02-21T16:46:06 < qyx_> anyway, just trolling like dongs
2015-02-21T16:46:10 < jpa-> ugfx has thread safety, so does nuttx's widgets, can't remember if ramtex has it.. pretty common :)
2015-02-21T16:46:16 < rbino> qyx_, I don't know if Miosix it's better in some way
2015-02-21T16:46:16 < Tectu> ugfx is quite advanced when it comes to features to be honest
2015-02-21T16:46:29 < Tectu> and what jpa- said. thread safety is quite easy and therefor common
2015-02-21T16:46:45 < rbino> but it was developed by a guy I know so it was my first step in the STM32 world, as easy as that
2015-02-21T16:46:50 < dongs> lux, http://i.imgur.com/vrgBVaa.jpg 5mm
2015-02-21T16:47:00 < jpa-> on the other hand, i'm not so sure if it is really a good idea to involve many threads in GUI drawing
2015-02-21T16:47:23 < Tectu> jpa-, that's why in uGFX you can enable and disable the feature as you need:   GDISP_NEED_MULTITHREAD
2015-02-21T16:47:29 < Tectu> qyx_, ^
2015-02-21T16:47:37 < jpa-> Tectu: i know, i have used the library sometimes you know
2015-02-21T16:47:47 < Tectu> jpa-, did the more fancy new video yet?
2015-02-21T16:47:52 < jpa-> nope
2015-02-21T16:48:12 < jpa-> too little time in my life
2015-02-21T16:48:23 < Tectu> either that or you moved to lazy town
2015-02-21T16:48:42 < jpa-> yeah, that also
2015-02-21T16:48:56 < jpa-> it's hard to be 100% productive on free time when i have to be 100% unproductive 7.5 hours per day
2015-02-21T16:48:58 < qyx_> too much sun outside

2015-02-21T17:11:07 < alex20032> I guess that now, when someone new come here, the family that people now recommend is the F0 and L0 (because of the free keil ide)
2015-02-21T17:11:43 < qyx_> huh
2015-02-21T17:12:08 < jpa-> umm, probably not
2015-02-21T17:12:30 < jpa-> the most loud people here are us freetards who couldn't care less about keil
2015-02-21T17:14:47 < GargantuaSauce> we should probably slap together a quick reference page with up to date links on getting your shit together
2015-02-21T17:14:50 < GargantuaSauce> and by we i mean not me
2015-02-21T17:15:44 < alex20032> why "we"? We should do it by us, and by us i mean not me :XD
2015-02-21T17:15:50 < jpa-> it would be 100% opinion piece anyway
2015-02-21T17:16:04 < jpa-> and since when has ##stm32 had an unified opinion on anything?
2015-02-21T17:16:24 < GargantuaSauce> well you can approximate objectivity by taking a bunch of different opinionated samples
2015-02-21T17:17:25 < qyx_> dongs could add his keil examples
2015-02-21T17:18:00 < alex20032> so dongs is for keil... at least some people here use keil
2015-02-21T17:18:07 < GargantuaSauce> i'd even concede that it'd be a good idea to have a section listing the eclipse-based solutions

2015-02-21T18:01:25 < emeb> apparently you can give someone a PCB layout tool but that doesn't make them a good designer.
2015-02-21T18:05:26 < jpa-> PaulFertser: hmm, yeah, actually non-stalling ETM tracing is quite realistic when TRACESWO freq = HCLK
2015-02-21T18:06:02 < Laurenceb_> this looks promising

2015-02-21T18:06:14 < Laurenceb_> id worry about the slip rings fusing
2015-02-21T18:06:18 < jpa-> PaulFertser: only indirect branches really need the branch packets, now that i properly follow the disassembly i can disable all other branch reporting and i only get the "N instructions executed" packets   http://koti.kapsi.fi/jpa/stuff/pix/sigrok_etm2.png
2015-02-21T18:06:33 < Laurenceb_> jpa-: interesting, i wonder if SWO could be abused as a data output portr
2015-02-21T18:06:56 < jpa-> Laurenceb_: well, for other than debug maybe not very well
2015-02-21T18:07:01 < PaulFertser> jpa-: amazing! How do you follow the disassembly btw?
2015-02-21T18:07:24 < jpa-> Laurenceb_: i think the closest to unformatted data is to put out stuff through ITM.. then you can control everything except a few bits in every 5th byte
2015-02-21T18:07:35 < jpa-> PaulFertser: parsing objdump output
2015-02-21T18:07:44 < Laurenceb_> ah
2015-02-21T18:07:48 < GargantuaSauce> damn that's cool
2015-02-21T18:07:58 < Laurenceb_> jpa-: how hard would it be to get elf loading to work?

2015-02-21T18:08:36 < Laurenceb_> those are just simultaneously recorded logic lines?
2015-02-21T18:08:43 < jpa-> Laurenceb_: what do you mean by elf loading?
2015-02-21T18:08:54 < jpa-> yeah, i'm recording led lines to see the latency in the trace
2015-02-21T18:08:57 < Laurenceb_> just load an elf directly into sigrok
2015-02-21T18:08:59 < Laurenceb_> ok
2015-02-21T18:09:11 < jpa-> Laurenceb_: well i just have to type the .elf name into a box
2015-02-21T18:09:21 < Laurenceb_> ok cool
2015-02-21T18:09:40 < Laurenceb_> so this isnt just a hardcoded hack?
2015-02-21T18:09:52 < PaulFertser> jpa-: any plans to decode multi-pin sync output? ;)
2015-02-21T18:10:04 < jpa-> like this http://kapsi.fi/~jpa/stuff/pix/sigrok_etm3.png
2015-02-21T18:10:10 < jpa-> PaulFertser: not yet
2015-02-21T18:10:32 < jpa-> PaulFertser: would just require an option to TPIU, other stuff could remain the same
2015-02-21T18:10:34 < Laurenceb_> oh cool
2015-02-21T18:10:48 < Laurenceb_> looks finished then :D
2015-02-21T18:10:55 < jpa-> pretty close yeah
2015-02-21T18:10:57 < PaulFertser> jpa-: that option is already there in openocd, I meant the sigrok side.
2015-02-21T18:11:07 < jpa-> PaulFertser: ah yeah
2015-02-21T18:11:18 < gxti> hm, neat
2015-02-21T18:11:22 < jpa-> PaulFertser: then just needs an option to feed in uart data from file, not sure if that exists already
2015-02-21T18:11:40 < jpa-> Laurenceb_: i still need to implement the N+1 branch packet formats
2015-02-21T18:11:58 < jpa-> https://github.com/PetteriAimonen/STM32_Trace_Example   here is the mcu side code
2015-02-21T18:12:01 < Laurenceb_> ok, i dont know how ETM works :P
2015-02-21T18:12:17 < PaulFertser> jpa-: I meant 2 or 4 bit wide sync port would require specific decoding by sigrok, it's not UART.
2015-02-21T18:12:28 < Laurenceb_> im guessing it works on the assumption that you can extrapolate where code is if it didnt branch?
2015-02-21T18:14:08 < emeb> how do you know which instr was conditionally skipped?

2015-02-21T18:17:35 < jpa-> PaulFertser: yeah, i mean that the TPIU decoder module needs changes if one wants to capture 2/4 bit trace with logic analyzer
2015-02-21T18:17:44 < jpa-> emeb: it is always the last one
2015-02-21T18:18:01 < jpa-> emeb: packet format is "E instructions executed, then 0 or 1 skipped instr"
2015-02-21T18:18:10 < emeb> aha - makes sense

2015-02-23T07:01:59 < GargantuaSauce> and is shorted out elsewhere
2015-02-23T07:02:17 < englishman> kV power at ground level... ya no
2015-02-23T07:03:04 < kakeman> it detects trains
2015-02-23T07:03:13 < GargantuaSauce> ah i guess it's 600V usually used for powered rails
2015-02-23T07:03:14 < kakeman> train shorts rails
2015-02-23T07:03:42 < kakeman> in intersections and such
2015-02-23T07:04:23 < englishman> the beat is like a train passing over sections of track
2015-02-23T07:04:33 < englishman> but thats a big assumption
2015-02-23T07:06:10 < GargantuaSauce> makes sense. weird that it operates at 50hz though
2015-02-23T07:06:11 < kakeman> en.wikipedia.org/wiki/ALSN#mediaviewer/File:ALSNcode.png
2015-02-23T07:06:33 < kakeman> doesn't it look like the first one
2015-02-23T07:06:57 < kakeman> means go?
2015-02-23T07:07:46 < kakeman> http://en.wikipedia.org/wiki/Train_protection_system
2015-02-23T07:08:58 < kakeman> it is first one no doubt about it
2015-02-23T07:09:19 < GargantuaSauce> yeah you're right
2015-02-23T07:09:33 < kakeman> ¨what those are about I don't know
2015-02-23T07:10:04 < kakeman> how those work something about seperating parts of rails and stuff
2015-02-23T07:15:08 < kakeman> before there was stm32
2015-02-23T07:15:44 < kakeman> trains had moved mountains

2015-02-23T07:21:36 < emeb_mac> R2COM: no, we didn't, but I did do some research to make sure that the power levels we were using weren't in the range  of danger.
2015-02-23T07:22:08 < emeb_mac> I never had anything over about 50W and I was *very* cautious about that.

2015-02-23T07:29:22 < englishman> 50w aint no thang id be much more concerned about equipment
2015-02-23T07:30:48 < GargantuaSauce> yeah loose connector and it fries itself pretty quick
2015-02-23T07:31:49 < GargantuaSauce> yeah maintain some distance for sure
2015-02-23T07:31:55 < englishman> russians have safety limits?
2015-02-23T07:32:06 < englishman> max 10 minutes near exposed chernobyl core
2015-02-23T07:32:32 < GargantuaSauce> i am looking at the canadian regulations and they are expressed in terms of power density
2015-02-23T07:32:53 < GargantuaSauce> oh fcc's are too
2015-02-23T07:33:54 < emeb_mac> right - so I always stayed well away from that amp and made sure it had a good dummy load.
2015-02-23T07:34:07 < emeb_mac> never antennas
2015-02-23T07:34:17 < GargantuaSauce> i have a "5W" china usb wifi adapter that probably puts out a quarter of that
2015-02-23T07:34:28 < GargantuaSauce> and i can feel the pulses in my hand if i hold it in front of the antenna
2015-02-23T07:34:50 < GargantuaSauce> rf dummy loads are a thing
2015-02-23T07:35:10 < emeb_mac> R2COM: a giant 50 ohm resistor designed for a good match at the operating frequency.
2015-02-23T07:35:23 < emeb_mac> it's a huge thing with fins and N connectors.
2015-02-23T07:35:35 < emeb_mac> Actually a 40dB attenuator.
2015-02-23T07:35:40 < emeb_mac> yes - bought.
2015-02-23T07:37:47 < upgrdman_> would a shitty power resistor not work as a load? like the square ceramic $1 kind
2015-02-23T07:38:04 < GargantuaSauce> assuming you're in an anechoic chamber with no reflections R2COM
2015-02-23T07:38:29 < emeb_mac> upgrdman_: if you want to trust your health to the match you might get from that go ahead.
2015-02-23T07:38:36 < GargantuaSauce> i am sure you've noticed a microwave oven has hot and cold spots for example
2015-02-23T07:38:48 < emeb_mac> I've heard too many stories about cooked eyeballs
2015-02-23T07:39:10 < upgrdman_> emeb_mac, from power resistors?
2015-02-23T07:39:23 < emeb_mac> upgrdman_: from high-power RF.
2015-02-23T07:39:51 < emeb_mac> and if you hook a bog-standard power resistor to a strong RF source you can't be sure it's a good match.
2015-02-23T07:39:53 < GargantuaSauce> it's a calculation that ignores the environment
2015-02-23T07:40:09 < GargantuaSauce> assumes there is nothing around you but free space
2015-02-23T07:40:37 < GargantuaSauce> ok dude, i just hope you dont subject anyone else to rf based on these assumptions
2015-02-23T07:41:15 < GargantuaSauce> there could be areas where reflections constructively interfere to produce a much higher localized power density
2015-02-23T07:42:05 < GargantuaSauce> i wouldn't want to be in a room with an antenna emitting 50W, isotropic or otherwise
2015-02-23T07:42:25 < emeb_mac> heh
2015-02-23T07:45:10 < GargantuaSauce> for across a room?
2015-02-23T07:45:13 < GargantuaSauce> more like 10mW
2015-02-23T07:46:40 < emeb_mac> R2COM: this is the one I used -> http://www.birdrf.com/Products/Attenuators/100-watts/100-SA-Series_Bi-Directional-Attenuators.aspx#.VOq-p7DF8o8
2015-02-23T07:47:29 < emeb_mac> R2COM: a few hundred bucks
2015-02-23T07:48:45 < emeb_mac> sounds like a PITA
2015-02-23T07:49:23 < emeb_mac> probably makes more sense to build a cage and test in that if you can't afford a good load
2015-02-23T07:50:01 < emeb_mac> that was my thinking
2015-02-23T07:50:19 < GargantuaSauce> less expensive than new eyes for sure
2015-02-23T07:50:37 < emeb_mac> +1
2015-02-23T07:51:22 < emeb_mac> yep - no need for caution there
2015-02-23T07:52:01 < emeb_mac> we were testing @ high power one day & touched a coupler on the amp output. quite a tingle.
2015-02-23T07:52:22 < emeb_mac> no permanent damage to my finger, but it felt hot
2015-02-23T07:53:03 < dongs> ive touched 50W HF antenna once
2015-02-23T07:53:05 < dongs> it was not cool
2015-02-23T07:53:48 < emeb_mac> well it's weird - it's not high temp, just feels like burning.
2015-02-23T07:54:30 < emeb_mac> don't fuck with military radar
2015-02-23T07:54:51 < GargantuaSauce> yeah radar has to deal with the whole d^-4 thing so the power is scaled up accordingly
2015-02-23T07:58:26 < GargantuaSauce> yeah, consumer wifi gear tops out around there
2015-02-23T07:58:41 < GargantuaSauce> well, legally
2015-02-23T07:58:45 < emeb_mac> heh
2015-02-23T07:58:47 < kakeman> polish sterilisation is to keep your man parts against high power antenna for minute or so
2015-02-23T07:59:05 < emeb_mac> steely dan

2015-02-23T08:01:41 < kakeman> it whispers so to say

2015-02-23T08:17:59 < emeb_mac> jpa-: how goes the awesome debug dev?
2015-02-23T08:18:45 < jpa-> emeb_mac: pretty much complete, but got stuck with my example code not running properly after power-on-reset
2015-02-23T08:18:45 < kakeman> I have to go to wellfare shit and workforce office shiet and appartement stuff and enterpreuner course and maybe gym after that
2015-02-23T08:19:06 < emeb_mac> jpa-: details. :)
2015-02-23T08:19:12 < jpa-> emeb_mac: seems like STM32F100 doesn't allow writes to DBGMCU until openocd has enabled the debug side
2015-02-23T08:19:55 < emeb_mac> jpa-: that's weird
2015-02-23T08:20:12 < emeb_mac> so the thing won't work until the debugger tweaks it from outside
2015-02-23T08:20:14 < jpa-> yeah.. doesn't matter much for me, but someone might try this with bootloader-usart loading or something
2015-02-23T08:22:08 < jpa-> i took a look at the SWD traffic with sigrok, seems like it is either the "JTAG->SWD" command or "debug power on"; but during night i realized that i can pinpoint it more exactly with gpio; not sure if that's gonna help anything, but atleast i'll know what is going on
2015-02-23T08:22:18 < emeb_mac> so I was doing some stuff with STM32F427 in Em::Blocks
2015-02-23T08:22:48 < emeb_mac> discovered that the startup code doesn't define a bunch of the IRQ vectors that the 427 supports
2015-02-23T08:23:19 < emeb_mac> SAI and DMA2
2015-02-23T08:23:46 < jpa-> surprising that DMA2 is missing, because it is present on most F4's i think
2015-02-23T08:24:14 < emeb_mac> need to confirm that
2015-02-23T08:24:19 < jpa-> (if you happen to have an STM32F4 project up an running, it might be nice to see what   DBGMCU->CR = 1; printf("%08x", DBGMCU->CR); gives; but i have one in a box at work so i might try it myself also)
2015-02-23T08:24:31 < jpa-> (that executed after power-on reset without debugger connected)
2015-02-23T08:27:18 < emeb_mac> not DMA2. DMA2D
2015-02-23T08:27:25 < emeb_mac> the gfx stuff
2015-02-23T08:27:27 < jpa-> ah
2015-02-23T08:28:13 < emeb_mac> SAI1_IRQn,  LTDC_IRQn, LTDC_ER_IRQn, DMA2D_IRQn
2015-02-23T08:28:49 < emeb_mac> don't have an F4 system on the bench atm

2015-02-23T14:21:45 < dongs> lunix kernel versions are dumb anyway
2015-02-23T14:21:53 < dongs> shit all hit the fan when they changed from 2.6.whatever to some new shit
2015-02-23T14:21:57 < dongs> that still doesnt make sense
2015-02-23T14:24:17 < dongs> all i know is there's 2.6
2015-02-23T14:24:28 < dongs> and then there's "some dumb version where my driver doesnt work anymore"
2015-02-23T14:24:33 < dongs> which is anything past that
2015-02-23T14:24:51 < dongs> yet I can still rebuild a windows driver written in ~2000
2015-02-23T14:24:55 < dongs> and use it on a computer in 2015
2015-02-23T14:25:06 < dongs> and if it was a x86 driver, i dont even need to rebuild it
2015-02-23T14:25:10 < dongs> (onyl need to rebuild for x64)
2015-02-23T14:27:13 < owl-v-> There are some interesting stuff going on in ARM-64bit world
2015-02-23T14:27:39 < Fleck> curved hands doesn't mean it's shit :D
2015-02-23T14:28:23 < owl-v-> Tegra X1 looks interesting.
2015-02-23T14:29:39 < dongs> owl-v-: window 10 does/will run on arm
2015-02-23T14:29:50 < dongs> days of lunix being catch-all solution just because its free as in aids are numbered
2015-02-23T14:30:11 < Fleck> doubt that
2015-02-23T14:30:15 < dongs> keep doubting
2015-02-23T14:30:35 < Fleck> I will
2015-02-23T14:30:43 < dongs> probably something like 80% of lunix installs on embedded are ONLY because its free and they dont have to pay some license fee to rtos and they can just nigger together some garbage solution wiht pyhton or something else
2015-02-23T14:31:11 < dongs> but as soon as windows is available, all the pro solutions will jump to that
2015-02-23T14:31:14 < dongs> just like that
2015-02-23T14:31:21 < dongs> lunix has zero benefits other than cost
2015-02-23T14:31:24 < dongs> everything else is negative
2015-02-23T14:31:45 < Fleck> all that bloatware that will come with crapdows 10, noone will use it for serious stuff
2015-02-23T14:31:54 < dongs> haha bloatware
2015-02-23T14:32:00 < dongs> have you seen lunix or assdroid lately, bro?
2015-02-23T14:32:05 < specing> What is the size of the recent shitdoze installs?
2015-02-23T14:32:10 < specing> 50GB?
2015-02-23T14:32:14 < dongs> 4 fucking cores at 2ghz just so your screen can smoothly scroll?
2015-02-23T14:32:20 < Fleck> specing: right? :D
2015-02-23T14:32:29 < Fleck> CF cards will come back for crapdows 10 :D

2015-02-23T14:34:26 < Laurenceb> ive got one of these

2015-02-23T14:34:44 < Laurenceb> im using it to wake up a gopro camera
2015-02-23T14:34:54 < Fleck> shitty code on shitty OS :D
2015-02-23T14:34:58 < dongs> looks like some prebiased transistor shit
2015-02-23T14:35:02 < Laurenceb> but when i plug the gopro into my trigger unit, it triggers...
2015-02-23T14:35:07 < Laurenceb> im major confused
2015-02-23T14:35:23 < dongs> you should get some in SOT.1123 package
2015-02-23T14:35:30 < Laurenceb> it is sot
2015-02-23T14:35:37 < dongs> but not SOT-1123
2015-02-23T14:36:08 < Laurenceb> output capacitance is 3pF
2015-02-23T14:36:29 < owl-v-> I'm thinking... why would people want W10 on ARM?   definitely not for gaming...
2015-02-23T14:36:31 < Laurenceb> heh thats small
2015-02-23T14:38:03 < Laurenceb> GoPro epically failed?
2015-02-23T14:38:10 < jpa-> owl-v-: microsoft hopes they'll want it for same purposes as android
2015-02-23T14:38:12 < Laurenceb> if a 3pF cap can trigger it...
2015-02-23T14:38:32 < Laurenceb> maybe i should haxor a 10K resistor on to bias the transistor all the time
2015-02-23T14:38:49 < Laurenceb> oh.. GoPro runs lunix

2015-02-23T20:41:09 < jpa-> still have to write a blog post some time
2015-02-23T20:43:12 < englishman> cool
2015-02-23T20:43:48 < jpa-> then have to find the bug that made me do this in the first place :D
2015-02-23T20:45:48 < Laurenceb> if im using adc channel 1 on adc1 and adc2
2015-02-23T20:46:01 < Laurenceb> how can i switch adc1 to porta and adc2 to portb?
2015-02-23T20:46:11 < jpa-> uh, what?
2015-02-23T20:46:38 < jpa-> the ADCs have their own set of input channels in hardware, you cannot change them
2015-02-23T20:46:45 < PaulFertser> jpa-: great work indeed!
2015-02-23T20:47:02 < jpa-> ADC AN0 is not necessary pin 0 on any port
2015-02-23T20:47:36 < jpa-> PaulFertser: the openocd etm/itm config stuff looks nice also, have to try it out
2015-02-23T20:47:42 < PaulFertser> jpa-: I'm unsure it's accurate to imply that TPIU is only a formatter and can be disabled to get raw ITM data, as TPIU actually produces the trace stream in the given coding, formatter is just a part of it.
2015-02-23T20:48:32 < PaulFertser> jpa-: no etm yet at all, and ITM config would benefit from adding some other options, I was waiting for feedback on the existing code so haven't done that yet.
2015-02-23T20:48:41 < PaulFertser> DWT too needs more work.
2015-02-23T20:48:55 < Laurenceb> oh its pin 9
2015-02-23T20:48:57 < Laurenceb> yeah
2015-02-23T20:49:12 < jpa-> PaulFertser: is the wiki more accurate now? :)
2015-02-23T20:49:59 < PaulFertser> jpa-: yeah :)
2015-02-23T20:52:21 < PaulFertser> ETM decoder looks really cool
2015-02-23T20:53:47 < jpa-> it's a pretty cool format, especially when BRANCH_OUTPUT = 0; it is actually surprising how much you can deduce from just a stream of "12 exec, 1 skipped, 6 exec" etc.

2015-02-23T20:58:44 < Laurenceb> setup is linesw 70+
2015-02-23T20:58:57 < Laurenceb> i cant find the statefullness
2015-02-23T20:59:17 < jpa-> what kind of bug?
2015-02-23T20:59:18 < Laurenceb> i get all 0xff then all 0x00
2015-02-23T20:59:23 < Laurenceb> from the device
2015-02-23T20:59:29 < PaulFertser> Laurenceb: is it legal in the UK to use the opposite direction lane to improve visibility (peek farther inside the turn) before turning left?
2015-02-23T20:59:31 < jpa-> maybe the statefulness is on the chip end?
2015-02-23T20:59:32 < Laurenceb> so it runs fine at power up
2015-02-23T20:59:51 < Laurenceb> <PaulFertser> I havent heard of it being
2015-02-23T20:59:55 < Laurenceb> jpa-: maybe
2015-02-23T21:00:13 < Laurenceb> but i power cycle it and the use the SDN, which issues internal reset on the si446x
2015-02-23T21:00:15 < jpa-> do you reset the SI446x somehow before init?
2015-02-23T21:00:19 < Laurenceb> yes
2015-02-23T21:00:19 < jpa-> hmm
2015-02-23T21:00:20 < PaulFertser> Here the policemen seem to be recommending it: https://www.youtube.com/watch?v=pmYh1FWYtUA
2015-02-23T21:00:23 < Laurenceb> i cycle its power
2015-02-23T21:00:28 < zyp> PaulFertser, why wouldn't it be?
2015-02-23T21:00:30 < Laurenceb> <PaulFertser> news to me
2015-02-23T21:00:45 < zyp> assuming that the centerline doesn't indicate that you aren't allow to cross it
2015-02-23T21:00:52 < zyp> allowed*
2015-02-23T21:00:54 < Laurenceb> true
2015-02-23T21:01:09 < PaulFertser> zyp: local traffic laws here say one can switch to the opposite direction lane _only_ for passing slower traffic.
2015-02-23T21:01:11 < Laurenceb> so i boot up
2015-02-23T21:01:12 < jpa-> why in UK would you need to peek before turning left?
2015-02-23T21:01:17 < Laurenceb> it runs fine
2015-02-23T21:01:21 < Laurenceb> then i kill and run
2015-02-23T21:01:24 < Laurenceb> and get 0x00
2015-02-23T21:01:30 < Laurenceb> kill and run, get 0xff
2015-02-23T21:01:35 < Laurenceb> etc -it alternates
2015-02-23T21:01:57 < Laurenceb> i cant see how it can be stateful
2015-02-23T21:02:04 < PaulFertser> jpa-: to be more aware of the traffic and potential obstacles.
2015-02-23T21:02:06 < Laurenceb> unless i missed something on the stm32
2015-02-23T21:02:13 < Laurenceb> but i init all the io lines
2015-02-23T21:02:28 < Laurenceb> maybe its something to do with the spi peripheral?
2015-02-23T21:02:37 < Laurenceb> does line 143 look ok?
2015-02-23T21:02:45 < jpa-> PaulFertser: around here you are just supposed to slow down at the intersection :P
2015-02-23T21:03:06 < englishman> that looks dangerous
2015-02-23T21:03:34 < englishman> going across line just before oncoming car
2015-02-23T21:03:39 < PaulFertser> jpa-: well, I'm not talking about intersections, rather long fast turns.
2015-02-23T21:03:46 < jpa-> ah
2015-02-23T21:04:00 < englishman> if there is oncoming car around the corner you have to tighten your turn when already in it
2015-02-23T21:04:02 < zyp> PaulFertser, I'm not aware of norwegian laws stating either, and I've certainly done it myself, assuming it was legal
2015-02-23T21:04:12 < jpa-> yeah, not allowed here either AFAIK
2015-02-23T21:04:14 < Laurenceb> so is there some sort of spi reset proceedure that im missing?
2015-02-23T21:05:30 < englishman> those roads are already pretty narrow lol
2015-02-23T21:05:37 < englishman> with no shoulder
2015-02-23T21:06:10 < zyp> then again, where I grew up and lived until a couple of years after I got my license, there's a bunch of roads narrow enough to not have a centerline at all
2015-02-23T21:06:32 < zyp> and then you can drive where the fuck you want on it assuming no oncoming traffic
2015-02-23T21:08:05 < zyp> on roads with real slippery ice, I prefer to either stay in the middle, or close to the side where the wind is coming from, to have more of a buffer in case of gusts
2015-02-23T21:09:27 < zyp> englishman, looks plenty wide to me :p
2015-02-23T21:11:58 < zyp> https://www.google.no/maps/@69.150629,15.78146,3a,75y,244.98h,84.47t/data=!3m4!1e1!3m2!1sDt06jzeiTqa0Wv9wdKrS2g!2e0 <- I'm talking about shit like this
2015-02-23T21:12:01 < PaulFertser> Laurenceb: possibly unrelated, but when using the shit-library, I recommend to always use StructInit functions to guarantee that the struct you use will have sane values, it's too easy to miss a field (or to think it's irrelevant), and IIRC I've seen a very nasty bug with CAN pins initialisation because of that.
2015-02-23T21:12:19 < Laurenceb> ah well spotted
2015-02-23T21:12:20 < Laurenceb> thanks
2015-02-23T21:12:25 < zyp> (there's an even narrower part further south, but no streetview from there)
2015-02-23T21:12:41 < englishman> zyp
2015-02-23T21:12:43 < Laurenceb> im also going to force NSEL high before applying power
2015-02-23T21:12:45 < englishman> was driving in sweden last summer
2015-02-23T21:12:50 < englishman> those roads scared the shit out of me
2015-02-23T21:12:51 < Laurenceb> atm NSEL is floating
2015-02-23T21:12:54 < englishman> it barely fit two cars
2015-02-23T21:12:58 < zyp> wat
2015-02-23T21:13:01 < Laurenceb> that might glitch up the si446x in some cases
2015-02-23T21:13:07 < englishman> and the speed limit was like 90kmh
2015-02-23T21:13:13 < englishman> it was intense
2015-02-23T21:13:27 < zyp> englishman, swedish roads are usually wider than norwegian roads :p
2015-02-23T21:13:39 < PaulFertser> Laurenceb: line 143, 144, looks like not what you intended?
2015-02-23T21:13:39 < zyp> speed limit on my streetview link is 80
2015-02-23T21:13:42 < englishman> that one looks ok with no bends
2015-02-23T21:13:48 < englishman> but taking a corner around forest
2015-02-23T21:13:49 < englishman> oh man
2015-02-23T21:14:11 < Laurenceb> <PaulFertser> thats to make sure spi is empty
2015-02-23T21:14:29 < zyp> englishman, https://www.google.no/maps/@69.255301,15.957255,3a,75y,15.47h,87.4t/data=!3m4!1e1!3m2!1svQzBvynXbcli9TMJmYkVpA!2e0 <- like this?
2015-02-23T21:14:34 < zyp> speed limit is stil 80
2015-02-23T21:14:34 < PaulFertser> Laurenceb: the read should be inside the loop, right?
2015-02-23T21:14:43 < englishman> narrower and tighter
2015-02-23T21:14:52 < Laurenceb> <PaulFertser> no
2015-02-23T21:14:54 < englishman> wow that is some remote area
2015-02-23T21:14:58 < Laurenceb> wait for spi to send anything
2015-02-23T21:15:02 < Laurenceb> then empty rx
2015-02-23T21:15:07 < PaulFertser> Ah, you check tx
2015-02-23T21:15:07 < Laurenceb> i just spotted something
2015-02-23T21:15:26 < Laurenceb> i might be powering the si446x through the gpio lines when i power cycle it
2015-02-23T21:15:36 < zyp> englishman, yeah
2015-02-23T21:16:51 < Laurenceb> oh fail
2015-02-23T21:16:59 < Laurenceb> i had that problem with the µSD card
2015-02-23T21:17:01 < Laurenceb> lol
2015-02-23T21:17:08 < englishman> https://www.google.no/maps/@58.464791,11.403917,3a,75y,43.52h,75.02t/data=!3m4!1e1!3m2!1shE7GDsPoA6tlo1ZpDBWJcw!2e0
2015-02-23T21:17:10 < englishman> does this work
2015-02-23T21:17:20 < zyp> yep
2015-02-23T21:17:23 < englishman> it wasnt this road but was this area
2015-02-23T21:20:00 < zyp> looks similar
2015-02-23T21:20:37 < zyp> so yeah, it's just that the default speed limit in sweden is 90, whereas it's 80 in norway
2015-02-23T21:20:58 < englishman> still seems insane :x
2015-02-23T21:21:07 < zyp> why?
2015-02-23T21:21:22 < englishman> because what do you do when theres another car coming
2015-02-23T21:21:30 < englishman> but youre busy turning a corner at 90kmh
2015-02-23T21:22:25 < zyp> you keep to your side when you don't have a clear view of oncoming traffic
2015-02-23T21:22:46 < englishman> but, theres not enough room for two cars
2015-02-23T21:22:52 < englishman> so one would have to leave the road
2015-02-23T21:23:07 < englishman> i mean im sure theres a reason that the death rate isnt millions per year
2015-02-23T21:23:17 < englishman> from head on collisions
2015-02-23T21:25:34 < zyp> well, you're also supposed to maintain a speed that'll allow you to stop in time
2015-02-23T21:25:42 < stephendwyer> PaulFertser: my brother (engineer at jaguar/landrover) said they usually get employees to take driving lessons, and that is one thing you learn how to do (opposite lane on blind corners) to check for obstacles further out, especially on rural british roads with high hedges right beside the road...
2015-02-23T21:31:05 < zyp> 20:05:37 < englishman> with no shoulder
2015-02-23T21:31:18 < zyp> you said that like having no shoulder is unusual, how is it where you live?
2015-02-23T21:31:43 < englishman> most roads have a paved or unpaved shoulder
2015-02-23T21:31:53 < englishman> even in the parts with no winter snow
2015-02-23T21:32:09 < englishman> rocks/fence/hedge right next to the road is pretty rare
2015-02-23T21:33:10 < emeb> there are some nifty back roads here in Arizona with two lanes most of the way and occasional one-lane bridges.
2015-02-23T21:33:18 < zyp> in norway, only multi-lane highways and roads with barriers between opposing lanes tend to have shoulders
2015-02-23T21:33:32 < emeb> those are fun when there's traffic...
2015-02-23T21:34:07 < zyp> the latter is kinda by necessity, since you need to be able to pull over to let emergency vehicles pass
2015-02-23T21:36:22 < englishman> its really a necessity here. need somewhere to push all the goddamn snow :)
2015-02-23T21:37:16 < zyp> now you talk like norway doesn't have snow
2015-02-23T21:37:39 < zyp> and how the fuck is the road shoulder useful if it's full of snow?
2015-02-23T21:38:04 < englishman> its not, in winter
2015-02-23T21:38:15 < englishman> was driving on one of those yesterday
2015-02-23T21:38:25 < englishman> passenger side mirror scraping against the snowbank

2015-02-23T21:52:55 < Laurenceb> anyone know whats wrong with my pwm config here?
2015-02-23T21:52:56 < Laurenceb> https://github.com/Laurenceb/STM32_Launcher/blob/master/pwm.c

2015-02-23T21:54:34 < Laurenceb> erm
2015-02-23T21:54:41 < Laurenceb> wtf line 61
2015-02-23T21:55:00 < Laurenceb> that should have caused an asset error thing in stperiph lib
2015-02-23T22:02:08 < bvernoux> Laurenceb: if that can help you have a written a simple lib using latest STM32Cube driver
2015-02-23T22:02:09 < bvernoux> https://github.com/bvernoux/hydrafw/blob/master/drv/stm32cube/bsp_pwm.c
2015-02-23T22:02:28 < Laurenceb> ah
2015-02-23T22:02:30 < bvernoux> and it work fine on STM32F4 and shall work fine on F1 too as IIRC PWM is the same
2015-02-23T22:02:36 < Laurenceb> thanks
2015-02-23T22:03:28 < bvernoux> just becareful to use only 16bits for ARR for F1
2015-02-23T22:03:43 < bvernoux> in my case i'm using a 32bits Timer
2015-02-23T22:04:38 < bvernoux> and accuracy is perfect from 1Hz to 42Mhz
2015-02-23T22:04:54 < bvernoux> especially on freq < 100KHz
2015-02-23T22:05:28 < Laurenceb> yeah

2015-02-23T22:43:38 < Steffanx> F4x9/F4x6/F7 i think
2015-02-23T22:44:08 < Steffanx> oh 427/429 too
2015-02-23T22:44:16 < bvernoux> IIRC it's the maximum supported by SDRAM controller on F4x/F7x ...
2015-02-23T22:44:20 < bvernoux> 256MB
2015-02-23T22:45:10 < specing> for 256MB you'd need DDR2/DDR3 to be the cheapest
2015-02-23T22:45:17 < bvernoux> the only things missing on those big CortexM is a real MMU and not a MPU ;)
2015-02-23T22:45:51 < bvernoux> specing: yes 256MB is very expensive in SDRAM
2015-02-23T22:46:01 < bvernoux> 64MB is less than 10USD IIRC
2015-02-23T22:46:17 < specing> quite expensive
2015-02-23T22:46:48 < specing> considering that 4GB ddr3 is ~30 usd
2015-02-23T22:47:04 < bvernoux> yes but there is no DDR3 controller on MCU :(
2015-02-23T22:47:50 < specing> time for cortex-a?
2015-02-23T22:48:09 < bvernoux> or cortex R ;)
2015-02-23T22:49:16 < bvernoux> or hydrbid CortexA + M  like in TI latest CPU
2015-02-23T22:51:58 < bvernoux> anyway architecture of M7 is a must for lot of cool embedded stuff especially with DTCM & ITCM in addition to lot of SRAM ...
2015-02-23T22:52:58 < bvernoux> with gigabit eth it will be perfect ;)

2015-02-23T23:28:14 < Getty> yeah i actually never questioned on my C64 that the floppy drive was like "bigger" as the "PC" itself
2015-02-23T23:30:09 < GargantuaSauce> it also has a faster processor
2015-02-23T23:30:40 < Getty> lol really?
2015-02-23T23:31:04 < Getty> i never ever cared one bit about the inner content of the floppy drive (beside disassembling a broken one, but that was not very scientific)

2015-02-24T00:05:09 < ds2> 20-30MHz sampling rate
2015-02-24T00:05:35 < ds2> undersample to cover VHF
2015-02-24T00:05:53 < ds2> so if those are limited, I would like to hear what are better specs
2015-02-24T00:06:48 < ds2> oh and no cheating with down converters either
2015-02-24T00:07:37 < ds2> I do see a potential problem with what i am thinking of - 8bit sample sizes
2015-02-24T00:07:38 < emeb> ds2: possible, but bandwidth will be narrow
2015-02-24T00:07:53 < ds2> emeb: why do you say narrow bw?
2015-02-24T00:08:15 < ds2> emeb: isn't 20-30MHz sampling rate higher then the RTL dongles?
2015-02-24T00:08:33 < emeb> you may be able to sample at 20-30MSPS but the processing you can apply in the BBB CPU will bottleneck
2015-02-24T00:08:48 < emeb> how fast can you tune / filter / demod?
2015-02-24T00:09:16 < ds2> emeb: I donno... how much math? that's the part that I don't have a thorough understanding
2015-02-24T00:09:18 < emeb> RTL dongles do much of the tuning prior to sampling in RF / analog
2015-02-24T00:09:29 < emeb> so sample rate out of the RTL dongle is only 1-2MSPS
2015-02-24T00:09:41 < ds2> isn't tuning just a band pass filter?
2015-02-24T00:10:03 < emeb> ds2: yes, but for good OOB rejection it needs to be a long filter.
2015-02-24T00:10:12 < emeb> which eats up CPU cycles
2015-02-24T00:10:24 < ds2> just for context... how many taps is a long filter?
2015-02-24T00:10:36 < emeb> that's why FPGAs are a good idea - you can do the tuning & filtering in the FPGA much more efficiently than in a CPU.
2015-02-24T00:11:07 < emeb> ds2: for the VHF receivers that I was doing recently we found that downsampling filters needed to be > 400 taps complex
2015-02-24T00:11:11 < emeb> so 800 taps total
2015-02-24T00:11:34 < ds2> how many bits are you starting with?
2015-02-24T00:11:41 < emeb> starting with 14 bits
2015-02-24T00:11:54 < ds2> I'd think in the long run, you have an upper limit on the taps based on number of bits
2015-02-24T00:12:09 < ds2> shouldn't the number taps go down if I am starting with 14 bits?
2015-02-24T00:12:14 < emeb> no
2015-02-24T00:12:30 < emeb> taps relates to the steepness of the transition band
2015-02-24T00:12:32 < ds2> don't I loose precision with too many bits?
2015-02-24T00:12:40 < ds2> too many taps I mean
2015-02-24T00:12:45 < emeb> no
2015-02-24T00:13:01 < emeb> more taps = longer filter = more integration = more precision
2015-02-24T00:13:34 < ds2> but isn't the process on a per tap basis: multiple with constant, add and scale so the registers don't overflow?
2015-02-24T00:13:55 < emeb> scaling is usually done after all the addition
2015-02-24T00:14:02 < ds2> Ohhh
2015-02-24T00:14:09 < emeb> otherwise you get too much internal quantization noise
2015-02-24T00:14:16 < emeb> might as well not filter in that case
2015-02-24T00:14:24 < ds2> that's the stuff I was thinking of
2015-02-24T00:14:50 < ds2> this is 400 taps of a FIR?
2015-02-24T00:14:54 < emeb> yes
2015-02-24T00:15:08 < emeb> and that's after a CIC decimation by 256!
2015-02-24T00:15:19 < emeb> which picks up an additional 4 bits of precision.
2015-02-24T00:15:41 < ds2> what's a CIC decimation?
2015-02-24T00:15:47 < ds2> I am thinking on a simple level
2015-02-24T00:15:51 < emeb> cascaded integrator comb.
2015-02-24T00:16:02 < emeb> basically a bunch of MAWFs
2015-02-24T00:16:20 < ds2> let's say if things are simpified a bit - signal is a "broadcast band" signal...either AM broadcast or FM
2015-02-24T00:16:37 < ds2> that should simplify things
2015-02-24T00:17:13 < emeb> with broadcast AM you need to tune from 500kHz - 1700kHz. You could theoretically get away with sampling at 4MSPS.
2015-02-24T00:17:47 < emeb> the signal you want to demodulate is about 4kHz wide, so you need to decimate by a factor of 500 or so
2015-02-24T00:18:25 < emeb> so you sample at 4MSPS, tune to the frequency within that band, then filter / decimate by 500 to get an 8kSPS signal that you can convert from AM to audio.
2015-02-24T00:18:57 < ds2> is the "detection" done on the 8K signal or the 4M signal?
2015-02-24T00:18:58 < emeb> Probably doable on a BBB, but the decimation operation will eat up CPU.
2015-02-24T00:19:13 < ds2> I am not thinking of doing it all in the ARM
2015-02-24T00:19:14 < emeb> hopefully detection is done on the 8k signal
2015-02-24T00:19:25 < emeb> PRU?
2015-02-24T00:19:27 -!- Taxman [~sk@chaph.opaya.de] has quit [Ping timeout: 245 seconds]
2015-02-24T00:19:36 < ds2> AM detection math seems to be straight forward - I^2 + Q^2
2015-02-24T00:19:38 < ds2> yes
2015-02-24T00:19:49 < emeb> can you do a FIR on the PRU?
2015-02-24T00:19:57 < ds2> it has a hardware MAC block
2015-02-24T00:20:04 < emeb> what precision?
2015-02-24T00:20:21 < ds2> but 400 taps in real time might be more storage then it has
2015-02-24T00:20:32 < ds2> claims 32x32 multiplier with 64bit out
2015-02-24T00:20:42 < emeb> that's probably doable.
2015-02-24T00:20:49 < emeb> what's the clock rate of the PRU?
2015-02-24T00:20:55 < ds2> 200MHz
2015-02-24T00:20:59 < ds2> that's the limiting factor I think
2015-02-24T00:21:28 < emeb> so you're sampling at 4MSPS that gives you 50clocks per sample
2015-02-24T00:21:46 < ds2> if the results are comparable to the WW2 era regen. receivers, I'd be happy
2015-02-24T00:21:55 < emeb> probably can't do a FIR in the PRU, but you might be able to do a CIC.
2015-02-24T00:22:20 < ds2> I don't see why you can't do a FIR in the PRU
2015-02-24T00:22:24 < emeb> then do the cleanup on the ARM processor at a lower rate.
2015-02-24T00:22:37 < ds2> mem limitations should be the main constraint
2015-02-24T00:22:38 < emeb> ds2: you've only got 50 clocks/sample.
2015-02-24T00:23:05 < emeb> which means 50taps of FIR max. If it's a complex tuning operation that's 25 taps I&Q
2015-02-24T00:23:26 < emeb> less than that if you factor in moving data around and doing the actual sin/cos mixer operation.
2015-02-24T00:23:37 < emeb> but a CIC can do a lot of decimation with a few operations.
2015-02-24T00:24:00 < ds2> out(n) = f(n)*K1 + f(n-1)*K2 + f(n-3)*K3
2015-02-24T00:24:06 < ds2> that's a 3 tap FIR, right?
2015-02-24T00:24:20 < emeb> yes, but a 3-tap FIR is virtually useless.
2015-02-24T00:24:37 < ds2> just needed a verification on what an FIR is
2015-02-24T00:25:32 < ds2> thinking of some SIMD like things that can be done on the PRU

2015-02-24T00:27:03 < emeb> sure - that will expand the possibilities.
2015-02-24T00:27:35 < emeb> main thing is that the audio sample rate is a lot lower, so as much stuff you can do up front in PRU and then decimate the better.
2015-02-24T00:27:43 < emeb> for broadcast FM things get trickier.
2015-02-24T00:28:19 < emeb> the frequency range there is 88-108 - 20MHz. You'll need to have > 40MSPS sample rate to cover that without external tuning.
2015-02-24T00:28:37 < ds2> couldn't FM be - bandpass for 15KHz, then do the tan-1 (I/Q) per sample?

2015-02-24T00:29:03 < emeb> so you'll do the RF tuning externally?

2015-02-24T00:29:19 < ds2> bandpassing in PRU
2015-02-24T00:29:35 < emeb> explain further please
2015-02-24T00:30:23 < ds2> FIR filters are addative, right?
2015-02-24T00:31:04 < emeb> as in they are sum-of-products operations, yes.
2015-02-24T00:31:05 < ds2> just for comparism - your 400tap filter... roughly what order analog filter is that equiv. to?
2015-02-24T00:31:30 < emeb> strictly speaking the order of a FIR is taps-1
2015-02-24T00:31:34 < emeb> so 399 :)
2015-02-24T00:32:05 < ds2> then why is a 399order filter needed? analog radios seems to do well with maybe 8th order overall filtering?
2015-02-24T00:32:25 < emeb> shape factor
2015-02-24T00:32:38 < ds2> (tank circuit for tuning =~ 2nd order), and another tank in the IF
2015-02-24T00:32:59 < ds2> it would seem like a much lower order is workable but not ideal...is that statement accurate?
2015-02-24T00:33:09 < emeb> analog radios don't operate their filters at the carrier frequency.
2015-02-24T00:33:28 < emeb> they do superhet operations to get the center frequency down to IF and run the filters there.
2015-02-24T00:33:28 < ds2> they don't? how do they tune?
2015-02-24T00:33:43 < ds2> superhet requires tuning before conversion
2015-02-24T00:34:00 < emeb> no - conversion = tuning.
2015-02-24T00:34:07 < emeb> unless you mean roofing filters
2015-02-24T00:34:19 < emeb> but roofing filters are not highly selective.
2015-02-24T00:34:28 < ds2> if that's the thing that makes sure you don't convert the wrong sum/product, yes
2015-02-24T00:34:30 < emeb> the IF filters are where the selectivity is defined.
2015-02-24T00:34:39 < emeb> and those happen at lower frequencies.
2015-02-24T00:34:46 < emeb> where the shape factor is nicer
2015-02-24T00:35:07 < ds2> the broadcast IF filters is as few as 1 tank circuti on a AM radio
2015-02-24T00:36:38 < ds2> a common design uses 3 can inductors - LO, front tuning, IF
2015-02-24T00:37:00 < emeb> yes. but what you're talking about doing in dsp is equivalent to trying to do all the filtering at RF.
2015-02-24T00:37:34 < ds2> not sure if I understand the difference. isn't the order of the filters the same?
2015-02-24T00:37:51 < emeb> look at it this way.
2015-02-24T00:38:30 < emeb> the rolloff of a filter is 6db*order / octave right?
2015-02-24T00:38:37 < ds2> right
2015-02-24T00:38:43 < ds2> or 20db/decade
2015-02-24T00:38:57 < emeb> (actually order/2)
2015-02-24T00:39:26 < emeb> so you can get a lowpass filter that rolls off from 10kHz to 20kHz 6dB with only 2nd order
2015-02-24T00:39:42 < emeb> or you can get one that goes 10MHz to 20MHz with 2nd order
2015-02-24T00:40:20 < emeb> but you can't get 10010kHz to 10020kHz with 2nd order.
2015-02-24T00:40:38 < emeb> even though the difference is only 10kHz just like the 1st example.
2015-02-24T00:40:39 < ds2> Ohhh ratios are different
2015-02-24T00:40:43 < emeb> exactly
2015-02-24T00:40:54 < emeb> shape factor
2015-02-24T00:41:20 < emeb> so a narrow BPF with the same order is naturally wider at a higher center frequency.
2015-02-24T00:42:16 < emeb> so by doing conversions you lower the center frequency and the filters can be narrower for the same order
2015-02-24T00:42:48 < ds2> makes sense
2015-02-24T00:42:53 < emeb> so in DSP you need to do the same thing - lower the center frequency or sample rate to get more selectivity

2015-02-24T00:43:28 < ds2> hmmm then can I play the same superhet game in DSP?
2015-02-24T00:43:36 < emeb> yes, to an extent
2015-02-24T00:43:40 < ds2> multiple my raw 20MHz samples by a sine wave
2015-02-24T00:43:46 < emeb> yes
2015-02-24T00:43:55 < emeb> generated by an NCO and sine LUT.
2015-02-24T00:44:04 < emeb> but that's just part of the problem.
2015-02-24T00:44:10 < emeb> you also need to lower the sample rate.
2015-02-24T00:44:10 < BrainDamage> remember that when you do that you're shifting /all/ the spectrum
2015-02-24T00:44:38 < emeb> and in order to lower the sample rate without aliasing you need to <tada> filter. :)
2015-02-24T00:44:57 < ds2> yes, not trying to avoid filtering
2015-02-24T00:45:02 < ds2> trying to avoid a high order filter
2015-02-24T00:45:16 < ds2> if I can move it away...
2015-02-24T00:45:51 < emeb> ds2: the way that's often done efficiently is with CIC filters: http://en.wikipedia.org/wiki/Cascaded_integrator%E2%80%93comb_filter
2015-02-24T00:46:40 < ds2> let me read that and see if it is another name for a much simplier idea
2015-02-24T00:46:44 < emeb> so you mix down to near DC, or some low IF and then apply a CIC filter to reduce the sample rate
2015-02-24T00:46:55 < emeb> and then more complicated filters are easier to use at the lower rate.
2015-02-24T00:48:49 < ds2> a CIC filter does decimation? as in somelarge sample rate in and a slow sample rate of data comes out without aliasing?
2015-02-24T00:49:45 < emeb> yes
2015-02-24T00:49:59 < emeb> and the ratio can be *very* large
2015-02-24T00:50:01 < BrainDamage> the sampler handles the decimation part

2015-02-24T01:05:39 < emeb> moving average
2015-02-24T01:05:47 < emeb> or "boxcar" filter.
2015-02-24T01:05:53 < emeb> all taps have equal weight.
2015-02-24T01:06:57 < ds2> Ohhhhhh
2015-02-24T01:08:13 < emeb> has crappy frequency response, but with careful frequency planning you can make it work for you
2015-02-24T01:08:26 < emeb> esp if you do cleanup with a nice FIR at the lower sample rate.

2015-02-24T01:10:31 < emeb> well, there's some pretty good theoretical explanations for the CIC out there. It's not something I can really clarify in a few sentences...
2015-02-24T01:11:05 < emeb> but suffice that upstream of the sampling operation there are true integrators that have _everything_ in them.
2015-02-24T01:11:34 < emeb> they roll over periodically, but that rollover is invisible when taken into account in the downstream comb filters.
2015-02-24T01:12:03 < ds2> this has been an interesting discussion but things are floating a big above the head at the moment
2015-02-24T01:12:17 < emeb> it's a lot to absorb.

2015-02-24T01:17:25 < emeb> ds2: yeah - FM stuff gets too nasty since you have to worry about undersampling then.

2015-02-24T01:18:16 < GargantuaSauce> i think you are going to have a hell of a time implementing this on a low end soc
2015-02-24T01:18:18 < emeb> except you run into big fun with where the band edges are with respect to the zonals.

2015-02-24T01:18:56 < emeb> since FM is 88-108 it doesn't fit nicely into a 40MSPS zonal
2015-02-24T01:19:01 < ds2> avoiding the edges

2015-02-24T01:40:07 < _Sync_> well I made a few position controllers before
2015-02-24T01:40:20 < _Sync_> and I tried them on a clapped out axis
2015-02-24T01:40:30 < emeb> oh fun. :P
2015-02-24T01:40:50 < Laurenceb_> then you finally think you fixed it...
2015-02-24T01:40:50 < _Sync_> and they would start to oscillate
2015-02-24T01:40:58 < Laurenceb_> and the chaotic oscillatino starts up
2015-02-24T01:41:07 < Laurenceb_> i mean oscillation
2015-02-24T01:41:08 < _Sync_> ramping up so hard that they would bang between the backlash
2015-02-24T01:41:09 < Laurenceb_> although
2015-02-24T01:41:25 < Laurenceb_> i think i am being attacked by oscillatinos sometimes

2015-02-24T02:39:53 < emeb> _Sync_: I think that "natural" control systems like biological systems were some of the inspiration for "Fuzzy Logic" that was so popular about 20yrs ago.
2015-02-24T02:40:31 < emeb> less math, more rule-of-thumb
2015-02-24T02:43:45 < _Sync_> yeah
2015-02-24T02:44:33 < GargantuaSauce> i am still not clear on the relationship between fuzzy logic and probabilistic modelling
2015-02-24T02:44:48 < _Sync_> I just think that every control system lecture should have one of those lectures
2015-02-24T02:44:50 < ds2> is fuzzy logic machine learning?
2015-02-24T02:44:57 < GargantuaSauce> no
2015-02-24T02:45:09 < _Sync_> because a lot of EEs do not understand that they are designing stuff that is safety critical
2015-02-24T02:45:40 < superbia1> xd
2015-02-24T02:47:15 < GargantuaSauce> i dont think you even need to bring criticality into it, just the notion that a real system will not fully correspond to your a priori modelling

2015-02-24T03:03:50 < karlp> emeb et al, is the reason people don't use IIR more for the filters just because they can become unstable? the modelling I did of "classic" FIR filters for the digital bandpass I needed, was _never_ going to work on L1, but IIR worked out just fine.  the fir designs were way too many taps to calculate in time
2015-02-24T03:04:24 < emeb> karlp: FIR filters are unconditionally stable
2015-02-24T03:05:01 < emeb> IIR filters can oscillate and/or limit-cycle. They also have noise issues and are susceptible to different behavior depending on the architecture.
2015-02-24T03:05:10 < ds2> if you take out positive feedback...
2015-02-24T03:05:12 < GargantuaSauce> http://sipi.usc.edu/~kosko/Fuzziness_Vs_Probability.pdf
2015-02-24T03:05:33 < emeb> ds2: IIR filters must have feedback or they aren't IIR
2015-02-24T03:05:53 < BrainDamage> the feed forward part is FIR, the feedback is the IIR
2015-02-24T03:05:58 < ds2> emeb: yes.
2015-02-24T03:06:28 < emeb> the big advantage of IIR is that you can often get a much steeper response for less multiplies & adds than the equivalent FIR.
2015-02-24T03:06:47 < karlp> so is the problem just that it's too hard to know ahead of time whether you'll have those problems?
2015-02-24T03:07:12 < emeb> karlp: it takes some analysis, but you can know that in advance.
2015-02-24T03:07:38 < karlp> I just remember that almost allll the reading I was doing was, "this is an IIR, don't use them, they can oscillate"
2015-02-24T03:07:40 < emeb> it's more a matter of trading off design time vs hardware resources.
2015-02-24T03:07:52 < karlp> and I was just, "the fuck you think I'm going to do 40 taps?!"
2015-02-24T03:08:00 < emeb> heh - that's throwing out the baby with the bathwater. :)
2015-02-24T03:08:28 < BrainDamage> the FIR limited slope comes from the fact that all poles are fixed in the origin
2015-02-24T03:09:01 < BrainDamage> IIR allows you to move them ... even past the unitary circle's stability limit
2015-02-24T03:10:19 < emeb> I use IIRs in audio stuff all the time.
2015-02-24T03:10:38 < emeb> and sometimes in RF / comm, but usually not
2015-02-24T03:10:50 < ds2> what is the basis for an IIR filter? a FIR filter is convolution
2015-02-24T03:10:55 < emeb> IIRs are a lot harder to get linear phase
2015-02-24T03:11:09 < BrainDamage> convolution applies to any linear system's transfer function
2015-02-24T03:11:50 < BrainDamage> if you know Z trasform IIR and FIR becomes only the numerator and denominator of the transfer function
2015-02-24T03:12:11 < karlp> I still don't get the phase issues, but I guess that's because my signals didn't care (or I didn't, yet)
2015-02-24T03:12:30 < karlp> like, ho the fuck cares if it shifts it phase, it does it all the time!
2015-02-24T03:12:55 < emeb> karlp: the issue is that nonlinear phase means the time delay of some frequency is different from others.
2015-02-24T03:13:05 < emeb> that causes smearing in time of the signal as it goes thru
2015-02-24T03:13:11 < emeb> not good for communications.
2015-02-24T03:13:20 < karlp> I guess, I was just bandpassing and doing an RMS aanyway,
2015-02-24T03:13:42 < GargantuaSauce> freedom impulse response?
2015-02-24T03:13:50 < emeb> heh
2015-02-24T03:13:59 < Roklobsta> French Impulse Response
2015-02-24T03:14:01 < karlp> islamic impulse response
2015-02-24T03:14:07 < emeb> you can make FIRs have nonlinear phase.
2015-02-24T03:14:08 < karlp> clearly iir is evil then I gues.
2015-02-24T03:14:18 < emeb> but most FIR design algorithms don't do that.

2015-02-24T05:29:21 < zyp> well, I don't remember
2015-02-24T05:29:59 < zyp> last time I needed some, I picked them up from digikey along with vacuum tweezers, just to hit the free shipping limit

2015-02-24T05:31:07 < emeb_mac> dongs told me where to get them
2015-02-24T05:31:14 < zyp> but I considered them free since I would otherwise pay shipping :p

2015-02-24T17:13:16 < zyp> I mean, if 87M/s over CF-SATA is too slow, presumably he has a CF card that can go faster, so that's not where the bottleneck is

2015-02-24T17:24:21 < zyp> place one of them upside down
2015-02-24T17:24:34 < dongs> yeah thats not gonna fly
2015-02-24T17:24:39 < jpa-> or on opposite side of board :)
2015-02-24T17:24:39 < dongs> im not placing bga on both sides
2015-02-24T17:25:16 < jpa-> put them side by side, with the pins facing the same way, then connect on another layer
2015-02-24T17:25:17 < Laurenceb> or vias?
2015-02-24T17:25:28 < dongs> jpa-: considered that
2015-02-24T17:25:31 < dongs> then i need 2 vias
2015-02-24T17:25:32 < dongs> i guess,
2015-02-24T17:25:36 < dongs> better than 2 connetors
2015-02-24T17:25:45 < jpa-> definitely better
2015-02-24T17:25:53 < dongs> but they're kinda pass-through
2015-02-24T17:25:59 < dongs> and i have shit on other side
2015-02-24T17:26:02 < dongs> that i'd need to route out
2015-02-24T17:26:08 < dongs> so it would look real ugly 'backwards'
2015-02-24T17:26:23 < qyx_> toporouter to the rescue
2015-02-24T17:26:26 < dongs> of course, they dont support lane swapping either
2015-02-24T17:26:48 < jpa-> well you can also place one above another so that all interconnect is on the right and you have left side free for routing other stuff
2015-02-24T17:27:35 < jpa-> as soon as you can route on 2 layers and space is not critical, swapping the lanes is not that difficult (you can even maintain them at equal lengths)

2015-02-24T17:31:02 < dongs> and then do lanes like C-shape?
2015-02-24T17:31:08 < dongs> back to back or whatever, and swap them
2015-02-24T17:31:25 < dongs> i guess swapping shit on 2 layers is still better than connectors?

2015-02-24T18:56:18 < Laurenceb> better than tarduino
2015-02-24T18:56:34 < Getty> gxti: yeah 3/4 of a week thinking and then making it happen, was really hard to find the right way
2015-02-24T18:56:48 < gxti> the right way to do what
2015-02-24T18:56:49 < Getty> Laurenceb: i cant compare, i successfully avoided both, is that true? :)
2015-02-24T18:56:55 < Laurenceb> yes
2015-02-24T18:57:27 < Getty> gxti: if you have 1000 PWM steps, fading the values proper based on settings the user made like 6:00 = 0% to 18:00 = 100% and this with the perfect value for brightness (you know value set != brightness)
2015-02-24T18:57:49 < gxti> so your formula is gamma correction?
2015-02-24T18:58:15 < Getty> ? i dotn know if gamma correction involves "time" ?
2015-02-24T18:58:35 < Getty> the formula is about time... when the next value has to be set
2015-02-24T18:58:56 < gxti> i don't know what time has to do with brightness.
2015-02-24T18:59:12 < Getty> a lot, if you want to make a perfect fade
2015-02-24T18:59:25 < Laurenceb> lol ST
2015-02-24T18:59:27 < Getty> if you just take in brightness then 1% - 15% is the same value
2015-02-24T18:59:36 < Laurenceb> / Beginning of code///////////////////////#include "mbed.h"
2015-02-24T18:59:44 < Getty> so when a user does 1% to 50% or 15% to 50%, you get the same result
2015-02-24T18:59:50 < Getty> in my case you dont get the same result
2015-02-24T18:59:57 < _Sync_> that is why you gamma correct
2015-02-24T19:00:00 < gxti> you need more than 64 PWM steps to do gamma correction, but 64 gamma-corrected (perceptual) steps could be enough. no reason you couldn't have more though.
2015-02-24T19:00:02 < _Sync_> so you get linear brightness response
2015-02-24T19:00:20 < Getty> gxti: as said, i can do it over all 1000 steps, thats the beauty of my formula
2015-02-24T19:00:33 < gxti> i'm sure it's much amaze
2015-02-24T19:00:37 < Getty> gxti: there is really a difference between all % and the fade is always adapting ideal
2015-02-24T19:00:56 < Getty> gxti: it is awesome for the case, i tried to find something that does that, but everyone just goes down to the XX steps
2015-02-24T19:01:01 < gxti> but i want to make sure you know what gamma correction *is* before you run out working around the wrong issue
2015-02-24T19:01:20 < Getty> i do work with LEDs and controlling them since half a year now, i think i am fine
2015-02-24T19:01:35 < gxti> well, do you?

2015-02-24T19:02:46 < Getty> that cant be, i have 1000 steps, i have time, i must be able to solve it
2015-02-24T19:03:28 < jpa-> https://svn.kapsi.fi/jpa/led-controller/sw/src/leds.c  here is my gamma correction & led PWM
2015-02-24T19:03:35 < Getty> so what i did is like making a reference table, i took 86400 * 1000 steps, i checked up which value has how many steps, and stored that, then i do some math to use those reference numbers in a simple 3 step to get the right seconds
2015-02-24T19:03:45 < jpa-> though to get smooth fading down to 0 brightness in dark room, i needed to use 65536 steps
2015-02-24T19:03:54 < Getty> the calculation of that table took already forever on a real server 8-)
2015-02-24T19:04:37 < jpa-> basically, just   pwm = x * x / LED_MAX;   is a good approximation of gamma correction

2015-02-24T19:05:54 < jpa-> well the brightness perception is subjective and depends on person anyway

2015-02-24T20:12:48 < Getty> customer on call had really problem bringing the device up on in his network... totally awkward

2015-02-24T20:34:17 < Steffanx> Time to get out of hte house and visit the customer with your down debuggable device. If the customer is nice enough to let you debug it ..
2015-02-24T20:34:55 < Steffanx> Will the fish die when your device fails? (was some fish related device not?)
2015-02-24T20:36:48 < PaulFertser> Or teach customer how to use ettercap or dsniff to MITM and capture all the traffic :)
2015-02-24T20:37:13 < BrainDamage> absolutely nothing can go wrong with that

2015-02-24T20:43:23 < Laurenceb> ive got a datalogger board that will only boot if i have swd connected

2015-02-24T20:44:03 < Laurenceb> yeah thats what im thinking
2015-02-24T20:44:15 < Laurenceb> theres some sort of microsd card error with no swd
2015-02-24T20:44:27 < Getty> uh!!!!
2015-02-24T20:44:34  * Getty steps back
2015-02-24T20:44:42 < Laurenceb> its supposed to log the error to the card

2015-02-24T20:45:13 < Getty> i just wanted suggest ITM...... i am stupid
2015-02-24T20:45:14 < Laurenceb> yeah, but at least i know where the error is

2015-02-24T20:45:27 < Laurenceb> i have usart, ill have to set that up

2015-02-24T20:45:36 < Getty> was my next suggestion some other output

2015-02-24T20:47:57 < Getty> cause just for the sake of, i would try it without watchdog once to see if it at least happens slowly?
2015-02-24T20:48:00 < Getty> steffanx: brilliant!
2015-02-24T20:48:11 < Steffanx> iirc the bmp does some morse code blinking
2015-02-24T20:48:42 < Getty> that would be actually really an awesome tool, or?
2015-02-24T20:48:59 < Laurenceb> Getty: it looks like it hangs somewhere
2015-02-24T20:49:56 < Laurenceb> erm no
2015-02-24T20:50:09 < Getty> it does reboot?
2015-02-24T20:50:12 < Laurenceb> it kills itself at line 264
2015-02-24T20:50:15 < Laurenceb> yeah
2015-02-24T20:50:28 < Getty> remove the watchdog, just for the sake of, and see if it doesnt do that again

2015-02-24T21:06:50 < gxti> thanks for helpful tip

2015-02-24T21:08:46 < Steffanx> specing and his avr assembly fetish.
2015-02-24T21:08:53 < Steffanx> i remembered that.
2015-02-24T21:08:56 < qyx_> mhm, "problems"
2015-02-24T21:08:59 < PaulFertser> I actually wonder what might be a sane reason nowadays not to use C++11 whenever you traditionally use C.
2015-02-24T21:09:01 < Steffanx> from my life in #avr
2015-02-24T21:09:13 < specing> Steffanx: GNAT nowadays
2015-02-24T21:09:37 < specing> Actually I still have only a semi-functional GNAT for native
2015-02-24T21:09:58 < specing> spent half the weekend compiling newer GNAT
2015-02-24T21:10:03 < specing> gcc is a bitch to build
2015-02-24T21:10:18 < GargantuaSauce> ive never had trouble building gcc it just takes ages
2015-02-24T21:10:40 < specing> speaking of that
2015-02-24T21:10:45 < specing> I just got a brilliant idea
2015-02-24T21:11:19 < GargantuaSauce> PaulFertser: one reason would have to be the fact that you have to define a sane subset of C++
2015-02-24T21:11:31 < GargantuaSauce> whereas C doesn't really have any features that you need to eliminate
2015-02-24T21:12:54 < PaulFertser> GargantuaSauce: but why would you? If you know assembly you basically understand what cost every feature you might want using has. And then do the usual tradeoffs counting thing.
2015-02-24T21:13:58 < GargantuaSauce> i mean things like exceptions or certain applications of templating
2015-02-24T21:14:11 < GargantuaSauce> that are absolutely ruled out for many projects
2015-02-24T21:14:20 < GargantuaSauce> that is a process you have to go through, adds to development load
2015-02-24T21:14:42 < GargantuaSauce> and if you're bringing in third party code there will be different subsets used and it makes things a pain
2015-02-24T21:15:21 < GargantuaSauce> rtti is another example
2015-02-24T21:16:12 < Getty> LOL watching saber ride "Mmmhhh it seems i need some keycard to enter here... lets take my star sherrifs badge.... haha its working"..... you just gotta love it
2015-02-24T21:16:17 < Getty> saber rider
2015-02-24T21:30:10 < PaulFertser> GargantuaSauce: btw, what applications of templating you consider bad? Regarding questionable features, I'd mention inheritance from non-abstract classes ;)
2015-02-24T21:31:53 < zyp> gxti, I'm using it exactly the opposite way around
2015-02-24T21:32:09 < zyp> // for permanent comments and /* */ for temporary disabling
2015-02-24T21:32:25 < gxti> it's completely arbitrary, like almost every style point
2015-02-24T21:32:43 < zyp> yeah
2015-02-24T21:32:50 < gxti> just based on what i feel it feels like
2015-02-24T21:32:52 < zyp> well, I'm using // for disabling single lines too
2015-02-24T21:33:22 < GargantuaSauce> mostly it not playing nicely with inheritance

2015-02-24T21:36:50 < GargantuaSauce> have you ever used the library glm?
2015-02-24T21:37:02 < GargantuaSauce> it is a vector math lib where every type and function is templated
2015-02-24T21:37:48 < specing> checking whether the C compiler (/tmp/portage/dev-lang/gnat-gpl-4.1.3.2008-r2/work/usr/bin/gnatgcc -O2 -pipe -fno-stack-protector -march=core2 -L/tmp/portage/dev-lang/gnat-gpl-4.1.3.2008-r2/work/usr/lib/gnatgcc/x86_64-pc-linux-gnu/4.1) works... no
2015-02-24T21:37:55 < specing> oops, wrong chan
2015-02-24T21:37:56 < PaulFertser> Sounds cool! In Haskell you can think of every function that doesn't have an explicit type signature as of a C++ templated one.
2015-02-24T21:38:07 < GargantuaSauce> and any time you slip up and use the wrong numeric type in an expression you get pages and pages of compile errors
2015-02-24T21:38:30 < specing> There was a C++ compile error contest
2015-02-24T21:38:42 < specing> the winner had over 8 billion lines of errors
2015-02-24T21:38:51 < PaulFertser> Concepts will help with that. Yep, the errors are horrible.
2015-02-24T21:39:28 < GargantuaSauce> and it can also be quite difficult to reason about the actual type of a particular expression
2015-02-24T21:41:03 < PaulFertser> If typechecking is ok, why bother? If not, you can add explicit type annotation and then the error should get more understandable. At least that's the case in Haskell :)

2015-02-24T21:46:28 < GargantuaSauce> also i have kind of an idealistic view that the core language and standard library should be separate
2015-02-24T21:46:58 < GargantuaSauce> but numerous c++ language features are tightly coupled to its standard library
2015-02-24T21:48:46 < GargantuaSauce> which coincidentally are the features that are almost universally cut out of embedded c++ applications

2015-02-24T22:16:37 < Laurenceb_> whenever i connect my target is in reset handler
2015-02-24T22:17:01 < PaulFertser> At least OpenOCD doesn't perform any kind of reset, you can attach to a running target and it even won't halt it until you ask.
2015-02-24T22:20:22 < bvernoux> Laurenceb: else try EmBlocks it work fine to attach without reset
2015-02-24T22:20:23 < PaulFertser> One can tell for sure about st-util with the help of Sigrok SWD dissector.
2015-02-24T22:21:35 < Laurenceb_> ooh good idea

2015-02-24T22:28:18 < bvernoux> spi init
2015-02-24T22:28:24 < Laurenceb_> oh
2015-02-24T22:28:41 < Laurenceb_> same code works on all my other boards
2015-02-24T22:29:00 < Laurenceb_> no issues in over 1000years uptime now :P
2015-02-24T22:29:16 < bvernoux> before to configure SPI it shall be disabled to be in a known state
2015-02-24T22:29:36 < bvernoux> anyway my reference is STM32F4 but F1 shall be similar
2015-02-24T22:29:42 < Laurenceb_> interesting
2015-02-24T22:29:57 < Laurenceb_> yeah i have spi bugs with my si446x driver too
2015-02-24T22:30:05 < Laurenceb_> that appear when debugger is disconnected
2015-02-24T22:30:16 < bvernoux> why you don't switch to stm32cube ?
2015-02-24T22:30:20 < bvernoux> spi work fine
2015-02-24T22:30:42 < bvernoux> the driver is really not bad
2015-02-24T22:30:58 < bvernoux> you can even do DMA with Polling without IT for special requirement ...
2015-02-24T22:31:22 < bvernoux> like for hard realtime streaming  ...
2015-02-24T22:31:35 < Laurenceb_> hmm
2015-02-24T22:31:41 < Laurenceb_> itd mean porting all my code
2015-02-24T22:31:51 < Laurenceb_> but maybe thats faster than debugging
2015-02-24T22:31:59 < bvernoux> yes but advantage is their hal work on F1 to F4
2015-02-24T22:32:04 < bvernoux> even other STM32 ...
2015-02-24T22:32:22 < Laurenceb_> shrug
2015-02-24T22:32:27 < Laurenceb_> this is a one off project
2015-02-24T22:32:28 < bvernoux> only config is different because of different clock speed for each Fx
2015-02-24T22:32:56 < Laurenceb_> im going to port my main datalogger project to F4 and chibios
2015-02-24T22:33:25 < bvernoux> ha nice
2015-02-24T22:33:54 < bvernoux> what I do not like very much on chibios is USB driver
2015-02-24T22:34:13 < Steffanx> Laurenceb_, why you earth you still refuse to use openocd?
2015-02-24T22:34:18 < Laurenceb_> yeah me too
2015-02-24T22:34:25 < bvernoux> other stuff are very nice even if I ported all driver to use a generic bsp using stm32cube
2015-02-24T22:34:26 < Laurenceb_> the usb mass storage is slow
2015-02-24T22:34:42 < bvernoux> yes and limited ...
2015-02-24T22:34:47 < bvernoux> it's not a real usb stack
2015-02-24T22:34:58 < bvernoux> the one from stm32 is very nice
2015-02-24T22:35:09 < bvernoux> and very complete even if I have never found any benchmark
2015-02-24T22:35:26 < Laurenceb_> im getting 900kB/sec for mass storage
2015-02-24T22:35:36 < Laurenceb_> faster than any chibios benchmark
2015-02-24T22:35:43 < bvernoux> ha yes great
2015-02-24T22:35:48 < bvernoux> using stm32cube usb ?
2015-02-24T22:36:06 < bvernoux> i'm planning a board with ULPI for USB HS
2015-02-24T22:36:08 < Laurenceb_> no, stperiph lib
2015-02-24T22:36:14 < Laurenceb_> ah good idea
2015-02-24T22:36:36 < Laurenceb_> yeah i have customers with 80meg logfiles, so it needs to be faster ideally
2015-02-24T22:36:50 < bvernoux> yes if we could have stm32f4 with embedded HS PHY just 1
2015-02-24T22:37:05 < bvernoux> to avoid loosing all those IO for ULPI ...
2015-02-24T22:38:12 < bvernoux> a must have will be to have a m0 or m0+ core in addition to manage USB or fast peripheral and have the M4F free
2015-02-24T22:38:38 < bvernoux> I'm pretty sure ST will do something like that in future a bit like NXP
2015-02-24T22:39:08 < bvernoux> for fast datalogger it's a must have
2015-02-24T22:39:42 < bvernoux> even independant USB MSC / CDC ... without wasting time with IRQ in the main core
2015-02-24T22:41:08 < Laurenceb_> yeah
2015-02-24T22:41:22 < bvernoux> the most critical is for USB
2015-02-24T22:41:45 < bvernoux> and also fast SDcard transfer or better using SDIO
2015-02-24T22:43:15 < bvernoux> just for info on LPC43xx the M0 running @120MHz can handle 40MBytes/s ;)
2015-02-24T22:43:23 < bvernoux> of course using DMA
2015-02-24T22:43:42 < bvernoux> it's why it's not required a big MCU for such task
2015-02-24T22:44:00 < bvernoux> when I say 40MByte/s is with USB HS in streaming mode

2015-02-25T00:54:01 < Getty> wow thats impressive, this is all you need to make a field that can handle a) drop in of files and b) click on so that a file manager pops up https://gist.github.com/Getty/7e5eaa49a3d0587837ec (and then you have the file in the JS as blob and can do whatever you want with it)
2015-02-25T00:54:07 < Getty> no libs (beside jquery)
2015-02-25T00:55:53 < Steffanx> and its not that hard to do that with pure js
2015-02-25T00:56:08 < Steffanx> without jquery i mean
2015-02-25T00:56:11 < Getty> yeah the jquery is totally optional actually it blows it up a bit
2015-02-25T00:56:33 < Steffanx> a bit :P
2015-02-25T00:56:39 < Getty> ah no, .originalEvent is still shorter as .addEventListener
2015-02-25T00:56:46 < Getty> it is tight! ;)
2015-02-25T00:57:37 < Getty> but now restore a backup is pure luxury ;)
2015-02-25T00:58:27 < Getty> and the awesome part is, cause the backup is just a messagepack i can directly make validity check in the javascript, dont need to make any MCU code for that
2015-02-25T00:58:51 < Steffanx> no alert je jquery-dialog style?
2015-02-25T00:59:09 < Getty> not yet ;) i let the designer do that

2015-02-25T01:15:27 < bilboquet_> When i see the price difference between STM32F401CE 3.54€ and STM32F103CB 6.12€. it came to me a question. What is the advantage to choose the STM32F103CB ?
2015-02-25T01:15:49 < bilboquet_> consumption ? I'm not sure.
2015-02-25T01:20:20 < Getty> i dont know specifics about those 2 but in general a price range can be pretty unrelated to the feature set ;)
2015-02-25T01:20:22 < Lux> check ali express ;)
2015-02-25T01:20:37 < Lux> you can get the f103 for like 2$ a piece
2015-02-25T01:20:44 < englishman> stm32f1 at 6eur.... something is wrong :)
2015-02-25T01:21:04 < englishman> $2 is an ok price for small qty
2015-02-25T01:21:13 < GargantuaSauce> i see those currency characters as apples

2015-02-25T01:22:35 < GargantuaSauce> but yeah the answer is that is the wrong supplier
2015-02-25T01:22:45 < englishman> bro do you even utf8
2015-02-25T01:23:05 < bilboquet_> i just looked quickly to mouser
2015-02-25T01:24:54 < zyp> looking at any one distributor does not necessarily give you the true price of a product, just an upper bound
2015-02-25T01:24:59 < Laurenceb_> should peripherals always be DeInit before use?
2015-02-25T01:26:05 < englishman> its not necessary
2015-02-25T01:26:16 < englishman> but if youre reusing periphs its probably good practice
2015-02-25T01:26:50 < specing> bilboquet_: package is often the costliest part of the chip
2015-02-25T01:28:11 < zyp> specing, the two chips mentioned are both 48-pin packages
2015-02-25T01:28:35 < specing> perhaps the 1* one is made in a much larger node?
2015-02-25T01:29:44 < zyp> nah, the f103cb is real common
2015-02-25T01:29:55 < zyp> the price is definitely too high
2015-02-25T01:31:41 < bilboquet_> i'm going to look around.  but the f4 looks pretty :)

2015-02-25T05:06:47 < dongs> oh
2015-02-25T05:07:11 < dongs> i cant find stencil for something I need to fucking assemble today

2015-02-25T05:18:45 < dongs> fffff
2015-02-25T05:21:11 < zyp> awesome
2015-02-25T05:21:24 < dongs> ya totally
2015-02-25T05:21:40 < dongs> im so pissed im just gonna turn it off and go murder some R2COMs in ARMA3
2015-02-25T05:22:21 < dongs> I got other shit i need to assemble too, but i would have to unload half the fucking reels to switch to it
2015-02-25T05:22:25 < dongs> so fuck that
2015-02-25T05:23:57 < zyp> I need to stop being fucking lazy and continue on the F4 board
2015-02-25T05:24:25 < dongs> did you make it bigger yet
2015-02-25T05:24:37 < zyp> didn't do shit since last week
2015-02-25T05:24:42 < dongs> nice
2015-02-25T05:24:44 < dongs> thats the way to do it
2015-02-25T05:24:58 < zyp> I know, right
2015-02-25T05:26:06 < zyp> why do you think it needs to be bigger?
2015-02-25T05:26:19 < emeb_mac> building that BBB format STM32F427 board
2015-02-25T05:26:28 < emeb_mac> a few more parts and I can power up
2015-02-25T05:26:39 < dongs> oh i duno
2015-02-25T05:26:56 < zyp> http://bin.jvnv.net/f/ULJwm.png <- still plenty of area left, can't be that hard to fit the buck regulator
2015-02-25T05:27:09 < zyp> and a couple of buttons
2015-02-25T05:28:21 < GargantuaSauce> wats the connector on the middle right
2015-02-25T05:28:46 < dongs> uh.. usb??
2015-02-25T05:29:16 < GargantuaSauce> is it a footprint for multiple types of connector or something
2015-02-25T05:29:21 < dongs> nope
2015-02-25T05:29:28 < dongs> just regular smt/dip microusb
2015-02-25T05:29:31 < dongs> that i also use
2015-02-25T05:29:36 < zyp> yeah
2015-02-25T05:30:06 < zyp> it's pretty much the footprint the datasheet calls for
2015-02-25T05:31:45 < zyp> http://bin.jvnv.net/f/NxjXQ.JPG <- connector looks like this (when somebody fucks up assembly)
2015-02-25T05:31:59 < dongs> heh heh
2015-02-25T05:32:25 < englishman>  that looks familiar
2015-02-25T05:32:42 < GargantuaSauce> i find the through holes + ground pads kind of weird
2015-02-25T05:33:03 < dongs> GargantuaSauce: it gives it less chances to get torn off the board
2015-02-25T05:33:06 < zyp> I even have a bottom view of the connector: http://bin.jvnv.net/f/g1Ja8.JPG
2015-02-25T05:33:21 < zyp> http://bin.jvnv.net/f/s177m.JPG <- which came off this :p
2015-02-25T05:34:23 < dongs> why u roll parts around carpet
2015-02-25T05:34:28 < dongs> before take pic
2015-02-25T05:34:48 < zyp> you'd have to ask the guy who broke that board
2015-02-25T05:34:59 < dongs> chinagirl is ignoring me today too, but im hearing some pcb dudes are back tomrorw
2015-02-25T05:35:05 < dongs> so im guessing so is everyone else
2015-02-25T05:35:18 < dongs> did you have a list of shit for me to ask?
2015-02-25T05:35:23 < dongs> you can like email it and stuff
2015-02-25T05:35:27 < zyp> oh, right
2015-02-25T05:35:43 < zyp> I'll do that tomorrow, i.e. tonight your TZ
2015-02-25T05:35:55 < dongs> ok
2015-02-25T05:37:07 < dongs> i guess i can assemble fucking NES carts
2015-02-25T05:37:10 < zyp> I was curious to see how that guy had managed to rip off that connector, so I gave him a free replacement for returning the broken board
2015-02-25T05:37:11 < dongs> that only needs one reel
2015-02-25T05:37:42 < zyp> I figure those pictures were worth it :p
2015-02-25T05:56:35 < kakeman> what do you say about going with 0.15mm wires in pcb?
2015-02-25T05:56:56 < kakeman> in logic signals
2015-02-25T05:57:54 < kakeman> no problemo?
2015-02-25T05:58:19 < englishman> why so big
2015-02-25T05:58:25 < kakeman> :D
2015-02-25T05:58:35 < kakeman> itead min.
2015-02-25T05:59:48 < kakeman> 0.2mm is ok with small distances and single logic loads i think
2015-02-25T06:00:09 < kakeman> I don't know why I use 0.6mm or so in some designs
2015-02-25T06:00:27 < kakeman> or 0.5mm

2015-02-25T06:11:37 < kakeman> it's just webm renamed
2015-02-25T06:11:41 < englishman> imgur cloning more like
2015-02-25T06:11:49 < englishman> gifycat still does it better
2015-02-25T06:15:36 < dongs> for some reason when i see gfycat i always think of 'go fuck yourself cat'
2015-02-25T06:15:43 < baird> Probably expecting us to pronounce it 'jiffy'. Like all the cool tumblr kids.
2015-02-25T06:31:51 < kakeman> sleep time

2015-02-25T08:45:02 < emeb_mac> dongs: do you have a favorite micro SD connector?
2015-02-25T08:45:20 < dongs> kinda, its the molex one, but its not really good i think
2015-02-25T08:45:27 < emeb_mac> ya
2015-02-25T08:45:28 < dongs> i only use it cuz i have it in stock + on a few projects
2015-02-25T08:45:31 < emeb_mac> that's what I used
2015-02-25T08:45:42 < dongs> ait nmot moelx

2015-02-25T08:45:45 < dongs> is watr i use

2015-02-25T08:46:06 < dongs> https://www.hirose.co.jp/cataloge_hp/e60900232.pdf ya that shit
2015-02-25T08:46:43 < emeb_mac> oops - I meant micro USB AB connector :P
2015-02-25T08:46:52 < dongs> da fuq
2015-02-25T08:47:02 < dongs> microusb is the stuff me + zyp use
2015-02-25T08:47:10 < dongs> fci
2015-02-25T08:47:48 < dongs> 10103594-0001LF	
2015-02-25T08:48:07 < zyp> it's not AB, it's B
2015-02-25T08:48:24 < emeb_mac> ah I want OTG
2015-02-25T08:48:27 < emeb_mac> so need ab
2015-02-25T08:48:28 < dongs> is there even difference in micro?
2015-02-25T08:48:31 < dongs> wasnt aware
2015-02-25T08:48:37 < zyp> but I would be surprised if you didn't find AB with same footprint
2015-02-25T08:48:39 < dongs> i thought they did away with that for micro and it was mini only
2015-02-25T08:48:54 < zyp> dongs, yes, AB is completely square
2015-02-25T08:49:00 < zyp> while B have the 45deg corners
2015-02-25T08:49:13 < zyp> F4 disco have AB
2015-02-25T08:50:03 < emeb_mac> yeah
2015-02-25T08:50:10 < zyp> of course, like all the other USB specs, manufacturers doesn't give a fuck and make OTG devices with B sockets
2015-02-25T08:50:11 < emeb_mac> I'm using similar part
2015-02-25T08:50:39 < emeb_mac> a nuisance to solder w/o doing reflow
2015-02-25T08:50:49 < zyp> so you'll find plenty of OTG stuff with a B plug on the end, with ID wired as A
2015-02-25T08:50:53 < emeb_mac> the pins are under that metal fork in the back
2015-02-25T08:50:58 < zyp> oh yeah
2015-02-25T08:51:05 < zyp> I did that some weeks ago
2015-02-25T08:51:11 < ds2> emeb_mac: how complete of an emulation is your STM32 board?
2015-02-25T08:51:32 < zyp> http://bin.jvnv.net/f/u9XvV.JPG <- I smeared solder everywhere on it
2015-02-25T08:52:13 < emeb_mac> zyp: you clipped the fork off?
2015-02-25T08:52:15 < emeb_mac> I did
2015-02-25T08:52:33 < zyp> no, I have a fine tip
2015-02-25T08:52:40 < emeb_mac> ds2: the BBB emulation is good enough for my capes
2015-02-25T08:53:08 < emeb_mac> zyp: I do too, but ended up with shorts so lotsa rework was needed.
2015-02-25T08:53:14 < ds2> emeb_mac: does it include the video and analog stuff?
2015-02-25T08:53:29 < zyp> emeb_mac, that's how I managed to smear solder outside the connector :p
2015-02-25T08:53:33 < emeb_mac> ds2: analog yes, spi & i2c & uart yes
2015-02-25T08:53:36 < ds2> emeb_mac: and does it include external memory?
2015-02-25T08:53:39 < emeb_mac> but no video
2015-02-25T08:53:56 < emeb_mac> ds2: it does have FSMC on the GPMC pins
2015-02-25T08:54:05 < emeb_mac> so some external memory could be supported
2015-02-25T08:55:02 < emeb_mac> zyp: yeah - it's ugly
2015-02-25T08:55:13 < emeb_mac> I'll need to think of a better way to do it next time
2015-02-25T08:55:17 < zyp> nice when properly reflowed though
2015-02-25T08:55:24 < ds2> oh
2015-02-25T08:55:35 < ds2> emeb_mac: thought about getting uCLinux on it?
2015-02-25T08:55:53 < zyp> ds2, why not just get a BBB at that point?
2015-02-25T08:56:21 < emeb_mac> zyp: yeah reflow may be best
2015-02-25T08:56:58 < emeb_mac> ds2: uclinux is not on my horizon
2015-02-25T08:57:05 < zyp> «so we have this board that runs linux, let's make a slower but compatible board and put a crippled variant of linux on it»
2015-02-25T08:57:34 < emeb_mac> I want bare metal and a lower-power, quieter processor for some RF & analog stuff.
2015-02-25T08:57:47 < ds2> zyp: BBB's have their own issues
2015-02-25T08:57:59 < emeb_mac> understatement. :)
2015-02-25T08:58:39 < ds2> a PSoC5LP would be more interesting
2015-02-25T08:58:54 < zyp> emeb_mac, sure, I can see that, but I don't see why you'd still want to put linux on it then :p
2015-02-25T08:59:00 < ds2> or one of those microsemi w/hard cores
2015-02-25T08:59:08 < emeb_mac> zyp: I don't. :)
2015-02-25T08:59:22 < zyp> of course, you tend to be sane
2015-02-25T08:59:40 < emeb_mac> tend
2015-02-25T09:00:10 < zyp> I don't make assumptions, I only speak from what I observe ;)
2015-02-25T09:00:24 < emeb_mac> :)
2015-02-25T09:00:32 < ds2> sanity is overrated
2015-02-25T09:00:44 < emeb_mac> ds2: haven't looked too closely at either of those families
2015-02-25T09:01:10 < zyp> is the psoc usable without marrying whatever IDE they have for it?
2015-02-25T09:01:19 < emeb_mac> I used some early PSoC parts and formed some low opinions of them
2015-02-25T09:01:30 < emeb_mac> they may be better now, but I don't know
2015-02-25T09:02:09 < emeb_mac> zyp: yeah - back then it was unusable w/o the windows IDE
2015-02-25T09:03:23 < ds2> sort of...the docs are available for the registers
2015-02-25T09:03:55 < ds2> M3 w/flexible stuff
2015-02-25T09:04:07 < zyp> even the registers for the flexible stuff?
2015-02-25T09:05:11 < zyp> I thought that shit were complex enough that you'd have to pass a schematic through their tool to get a configuration, similar to an fpga workflow
2015-02-25T09:05:30 < dongs> Did you know? Zyp is a lifetime member of USB-IF, and has 10 personal VIDs
2015-02-25T09:06:02 < zyp> that's news to me, why haven't anybody told me before?
2015-02-25T09:06:05 < ds2> that's the sort of part... they have the docs on what the settings do whereas the FPGA's don't document the bitstream
2015-02-25T09:06:23 < akaWolf> zyp: give me one VID pls :P
2015-02-25T09:06:55 < zyp> ds2, ok, that's cool at least
2015-02-25T09:07:16 < zyp> maybe worth a look some time then
2015-02-25T09:08:06 < ds2> the short coming I see is the limitations of the blocks is not well explained
2015-02-25T09:08:22 < ds2> so I assume everything on there is generic crap like 741 amps
2015-02-25T09:10:48 < emeb_mac> the analog stuff is not... great
2015-02-25T09:10:56 < emeb_mac> good for low frequency stuff
2015-02-25T09:11:05 < ds2> if even that
2015-02-25T09:11:25 < ds2> emeb_mac: compareable to a LM741 is a fair comment, right?
2015-02-25T09:11:54 < emeb_mac> for bandwidth, offset, accuracy yeah

2015-02-25T09:14:59 < emeb_mac> too bad - that was kinda cool

2015-02-25T09:45:54 < GargantuaSauce> jpa-: and if you look at the html it actually has two sources inside the video tag, mp4 and webm. your browser is preferring mp4 because your browser prefers to fellate the MPEG LA
2015-02-25T09:46:28 < owl-v-> some old elevators have 'F' instead.

2015-02-25T14:33:30 < dongs> its not pro at all
2015-02-25T14:33:36 < dongs> cuz i duno how im gonna route it
2015-02-25T14:33:50 < Getty> non germans are so not used to the irony concept ;)
2015-02-25T14:33:55 < Roklobsta> set autorouter and go to bed.  ;)
2015-02-25T14:34:24 < Roklobsta> uh germans don't do irony. they think they do but they really don't.
2015-02-25T14:34:29 < dongs> terrific idea
2015-02-25T14:34:52 < Roklobsta> can you put the chips on opposite side of PCB?
2015-02-25T14:35:00 < dongs> yes, but im not going to
2015-02-25T14:35:16 < Roklobsta> he is a stubborn one.
2015-02-25T14:36:04 < Roklobsta> are the red pads NC forever?
2015-02-25T14:36:10 < dongs> mostly
2015-02-25T14:36:15 < dongs> they're just some randomish signals
2015-02-25T14:36:39 < Roklobsta> can you get those two chips in a mirror image version?
2015-02-25T14:36:40 < dongs> only 4 more signals not connected on the smaller ones.
2015-02-25T14:36:45 < dongs> no, heh
2015-02-25T14:37:05 < PeterM> put chip on the left of chip, pop all signals stright down runaccross and popback upstraight into pads
2015-02-25T14:37:23 < dongs> yeah that was one of the suggestions
2015-02-25T14:37:26 < dongs> but i need the purple shit lined up
2015-02-25T14:38:14 < Roklobsta> so the chips can't move or rotate?
2015-02-25T14:38:28 < PeterM> dang

2015-02-25T14:40:18 < Roklobsta> or 180 the left 2, the purple would still be lined up
2015-02-25T14:42:04 < dongs> heh no, the left one left side green has to keep facing there
2015-02-25T14:43:10 < dongs> im gonna check one other possible replacement for the right side IC
2015-02-25T14:43:14 < dongs> maybe it will have correct lane order
2015-02-25T14:47:37 < Tectu> i'm searching for those totally normal 2x20pin IDC connectors on mouser.com
2015-02-25T14:47:41 < Tectu> but I can't find any -.-'
2015-02-25T14:47:59 < dongs> you mean 2.54mm shit?
2015-02-25T14:48:01 < dongs> pin headers?

2015-02-25T14:49:13 < Tectu> yes
2015-02-25T14:49:19 < Tectu> thing on the left
2015-02-25T14:49:26 < dongs> oh shrouded
2015-02-25T14:49:31 < Tectu> yes
2015-02-25T14:49:46 < Getty> Roklobsta: if a german gives you a compliment it is most often pure irony, only if the german triple approves that he means it real, then you can take it ;)
2015-02-25T14:49:53 < Tectu> I couldn't find those standard ones without any fancy shit on mouser :/

2015-02-25T14:53:34 < dongs> 20 vias in a row is gonna be bigger than the bga itself
2015-02-25T14:53:35 < dongs> lols
2015-02-25T14:53:46 < Tectu> dongs, searching on mouser ;-)
2015-02-25T14:54:17 < Tectu> what's that, jpa- ?
2015-02-25T14:54:42 < dongs> im checking a replacement for right side shit
2015-02-25T14:54:49 < dongs> maybe it will have right order
2015-02-25T14:55:09 < Roklobsta> real men don't use vias.
2015-02-25T14:55:12 < jpa-> dongs: stagger the vias?
2015-02-25T14:55:19 < dongs> jpa, still looks ugly

2015-02-25T15:35:26 < Laurenceb> the error is really regular

2015-02-25T16:50:13 < Steffanx> maybe because of his join/quit crap
2015-02-25T16:50:13 < dongs> i think his client was garbage

2015-02-25T16:50:22 < dongs> aka the huge one

2015-02-25T17:03:35 < Laurenceb> thats more likely to work

2015-02-25T17:04:30 < dongs> assdroid samples at like 10hz or something isnt it
2015-02-25T17:04:43 < Laurenceb> lulz

2015-02-25T17:05:19 < Tectu> "it worked" and then raging that it does not work

2015-02-25T17:05:22 < Tectu> I see the problem.
2015-02-25T17:06:27 < Laurenceb> BDU is completely non functional :P
2015-02-25T17:06:51 < Laurenceb> unless thats no the problem here
2015-02-25T17:07:13 < Laurenceb> the fact i get errors of >>256 suggests something else is wrong
2015-02-25T17:07:27 < Laurenceb> but they are always n*256

2015-02-25T17:45:27 < jpa-> 1GHz is still 30 cm bandwidth so you are not really even operating as a transmission line there.. so sharp corners are not terribly important AFAIK
2015-02-25T17:46:36 < jpa-> err, *wavelength
2015-02-25T17:51:01 < scummos> right angle is an impedance discontinuity so better avoid it if possible
2015-02-25T17:51:13 < scummos> not because of the right angle itself but because the trace is wider at that point
2015-02-25T17:51:32 < jpa-> scummos: but how to avoid it with vias?
2015-02-25T17:51:49 < scummos> "don't use vias" *grin*
2015-02-25T17:51:58 < scummos> for HF tracks if possible at all
2015-02-25T17:52:12 < jpa-> but not possible for dong's case
2015-02-25T17:52:20 < jpa-> so if it works anyway, who cares
2015-02-25T17:52:32 < scummos> yep, just do it and live with the signal degradation
2015-02-25T17:52:35 < scummos> :D
2015-02-25T17:53:24 < zyp> good thing trivial levels of degradation doesn't hurt the content of digital signals
2015-02-25T17:54:09 < jpa-> i wonder if the 1mm length of different impedance really matters anything at all for a signal with 30cm wavelength
2015-02-25T17:54:18 < dongs> if I can figure this out wihtout vias, my 1s will be oner and zeros will be zeroer
2015-02-25T17:54:30 < scummos> well i think such a via has an inductance of like 1nH
2015-02-25T17:54:34 < scummos> that does matter a bit at 1 GHz
2015-02-25T17:55:13 < jpa-> is inductance of vias higher than that of traces? why?
2015-02-25T17:56:14 < scummos> um, "i heard so" ;)
2015-02-25T17:56:38 < Laurenceb> it should be possible to impedance match a via
2015-02-25T17:56:45 < scummos> but probably hard
2015-02-25T17:56:59 < Laurenceb> easier than l3gd20
2015-02-25T17:57:03 < karlp> should maybe just sticky tape some plastic bags of rocks onto the board?
2015-02-25T17:57:11 < karlp> that will surely ocmpensate for the vias
2015-02-25T17:58:47 < englishman> Just design your boards with zero inductance and capacitance. Those only degrade signal quality
2015-02-25T17:59:07 < jpa-> in transmission lines, inductance and capacitance preserve signal quality :)
2015-02-25T17:59:48 < englishman> Clearly not a true audio aficionado. Go back to your Sony equipment pleb
2015-02-25T18:00:15 < englishman> That shit is full of capacitors
2015-02-25T18:00:26 < karlp> anyone have any opinions on forward references and why one style is better than the other? https://pastee.org/uf6zw
2015-02-25T18:01:00 < dongs> i typedef all my structs
2015-02-25T18:01:13 < dongs> having to type "struct" for every fucking thing is the lunix  way
2015-02-25T18:01:30 < scummos> forward declarations are good because they significantly reduce compile time in many situations
2015-02-25T18:01:44 < scummos> (compared to the #include)
2015-02-25T18:01:49 < dongs> uh wat
2015-02-25T18:01:55 < dongs> why would that even matter
2015-02-25T18:02:00 < zyp> eh, what projects are you doing that have significant compile times on a modern computer?
2015-02-25T18:02:17 < dongs> maybe he's building scummOS
2015-02-25T18:02:19 < dongs> on a 486
2015-02-25T18:02:42 < scummos> huh? for something like a moderately sized cpp project compile times matter a lot
2015-02-25T18:03:05 < PaulFertser> In C++ you can omit "struct" if you want.
2015-02-25T18:03:12 < scummos> it matters because the #include compiles the whole header for each file where it's included, while the forward decl is just one line the compiler has to read
2015-02-25T18:03:24 < dongs> scummos: it is 2015
2015-02-25T18:03:30 < dongs> compilers have this thing called "precompiled headers"
2015-02-25T18:03:36 < dongs> maybe gcc doesn't?
2015-02-25T18:03:46 < scummos> I don't think gcc has it by default
2015-02-25T18:03:47 < zyp> I believe even gcc does
2015-02-25T18:04:05 < scummos> okay, I don't want to insist, maybe my knowledge is outdated ;)
2015-02-25T18:04:12 < zyp> ref. https://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html
2015-02-25T18:04:57 < zyp> karlp, my opinion is that your project is a poor reason to use forward refs
2015-02-25T18:05:20 < dongs> i think they're poor in general
2015-02-25T18:05:26 < dongs> and don't look pro
2015-02-25T18:05:28 < zyp> yeah, I tend to not use them
2015-02-25T18:05:32 < karlp> my project is a poor reason? sorry?
2015-02-25T18:05:42 < karlp> so, use the includes in the common header you mean?
2015-02-25T18:05:45 < zyp> sorry, I meant situation, not project
2015-02-25T18:06:17 < karlp> this is for a plain C project anyway right now

2015-02-25T18:07:06 < karlp> compile times have never been an issue for these projects, I'm more interested in making sure that code assistance works well
2015-02-25T18:07:07 < zyp> in my opinion, a library might declare opaque forward refs for internal structures that you're not supposed to touch the internals of, but declaring them yourself in your code is pointless
2015-02-25T18:07:34 < karlp> that's what I was feeling, I just thought there was reasons not to use lots of includes in the "app" common include.
2015-02-25T18:07:36 < dongs> karlp: well then even less reason to use forwards
2015-02-25T18:07:49 < dongs> because if you dont include the header how is code assistance supposed to guess waht your struct has?
2015-02-25T18:08:03 < dongs> i mean it'll probly work but
2015-02-25T18:08:06 < dongs> shrug
2015-02-25T18:08:34 < karlp> dongs: indeed, that's the motivation to use the headers instead.
2015-02-25T18:08:55 < karlp> they're actually all opaque anyway though, so no need for their internals
2015-02-25T18:09:02 < karlp> (in this case)
2015-02-25T18:09:28 < zyp> karlp, well, I think the main question you have to ask yourself is what's the benefit of not having the includes there?
2015-02-25T18:09:58 < karlp> I was wondering if it was going to cause more compilation problems or namespace pollution or was just a generally discouraged thing to do
2015-02-25T18:10:55 < zyp> I think having the includes in a common place eases maintainability
2015-02-25T18:11:29 < karlp> would you then _not_ reinclude them in the .c files that actually use those libraries? rely on the include from the shared app.h?
2015-02-25T18:11:43 < zyp> if I have access to a variable of a certain type, I usually expect to be able to use it too, without requiring additional includes to give me the full declaration of it
2015-02-25T18:11:46 < zyp> yep
2015-02-25T18:12:10 < karlp> you also tend to put alllll your code into a single file don't you?
2015-02-25T18:12:27 < karlp> don't some of your stm32 projects have the entire thing in a single heade3r file or something?
2015-02-25T18:12:46 < zyp> I'm talking of larger stuff, don't get personal :p
2015-02-25T18:14:52 < zyp> my reasoning is that if main.c includes a.h declaring struct A which includes a reference to struct B, I think of b.h as an implicit dependency and thus don't see a need for including it explicitly in main.c
2015-02-25T18:15:23 < karlp> reasonable
2015-02-25T18:15:38 < zyp> then again, I mainly write C++, not C
2015-02-25T18:15:55 < karlp> yeah, thinking of leaving this one as C, one more time...
2015-02-25T18:16:30 < zyp> in C you can have an opaque struct foo_ctx and a bunch of functions like foo_x(foo_ctx*)
2015-02-25T18:17:17 < zyp> whereas a C++ API would have a class Foo, and a Foo::x()
2015-02-25T18:18:02 < zyp> and member functions wouldn't be accessible through opaque forward refs, so it doesn't make sense to me to use them :)
2015-02-25T18:18:45 < jpa-> karlp: my reasoning is that this doesn't matter at all :)
2015-02-25T18:19:22 < zyp> oh, and there's another point to consider
2015-02-25T18:19:39 < zyp> what happens when the library changes the struct name?
2015-02-25T18:19:59 < karlp> part of the api, so it won't work either way
2015-02-25T18:20:04 < zyp> if you don't use forward refs, you get an error everywhere you try using the old name
2015-02-25T18:21:10 < zyp> if you do use forward refs, you get errors about incompatible types everywhere you try passing a variable of your forward reffed type into a library function
2015-02-25T18:22:11 < zyp> which to me sounds more messy

2015-02-25T18:51:22 < pgomes> thanks a lot for the suggestions. Will try it out ...
2015-02-25T18:51:59 < owl-v-> omg. dead bug style.
2015-02-25T18:52:00 < dongs> cool, i spent time to figure out autoneckdown stuff
2015-02-25T18:52:08 < dongs> with room definitions
2015-02-25T18:53:24 < dongs> oh zyp, chinagirl isnt back until march 1st
2015-02-25T18:53:29 < dongs> so you got plenty of time to dick around with that list
2015-02-25T18:53:44 < dongs> http://i.imgur.com/K9qo70L.png < autoneckdown
2015-02-25T18:53:51 < zyp> dongs, right, ok
2015-02-25T18:54:54 < owl-v-> do you solder BGA by hand?
2015-02-25T18:56:05 < zyp> dongs, solder mask clearance looks too big again
2015-02-25T18:56:36 < dongs> zyp, this is ipc recommended (tm) for 0.5mm pitch on non-hdi boards
2015-02-25T18:56:46 < zyp> hdi?
2015-02-25T18:57:06 < dongs> as in no laser-drilled vias + other shit
2015-02-25T18:57:33 < dongs> 'high density interconnect'
2015-02-25T18:57:50 < zyp> I find it weird that solder mask clearance is higher than pad/trace clearance
2015-02-25T18:58:14 < zyp> kinda makes the mask pointless

2015-02-25T19:00:25 < zyp> what's the pitch of that bga? .8?
2015-02-25T19:00:49 < dongs> 0.5 heh
2015-02-25T19:01:04 < dongs> i wouldnt be wasting time with neckdown if it was .8

2015-02-25T19:01:32 < zyp> ah, right
2015-02-25T19:02:36 < zyp> Mask Opening: 50 µm around pad
2015-02-25T19:02:42 < zyp> that's 2 mil
2015-02-25T19:02:56 < dongs> okok, looking. maybe i did fuck that up
2015-02-25T19:04:10 < dongs> ok, thanks :) fixing.
2015-02-25T19:04:45 < zyp> hmm, 3.2mil trace width and clearance
2015-02-25T19:04:49 < zyp> that's small :p

2015-02-25T19:21:56 < zyp> 1mm pitch though, so they were easy

2015-02-25T21:23:29 < Getty> stupid noob question, is there any other often used concept to make a delayed call beside like storing the "wish to call time" and check for this every rtc tick

2015-02-25T21:26:43 < gxti> depends on the duration and the precision, but no that's pretty much the entire idea.
2015-02-25T21:27:31 < Getty> oh lets say a minute duration and precision can be pretty low, its more like i have some "retry that later probably" moments, and i get sick of all those extra variables to store the times
2015-02-25T21:28:06 < Getty> its not a horrible situation ;) but i thought i give it a shot to ask if i miss something handy

2015-02-25T21:29:08 < gxti> the basic concept is you have a linked list sorted by time. instead of having aboslute times you can store the delta to the next event, and each tick you decrement the head of the list until it gets to 0 then it fires.
2015-02-25T21:29:37 < Getty> yeah ok... now where i got so many of them i might need to think about making something like that in the future

2015-02-26T03:37:33 < Getty> i just cant imagine he would just disconnect it without knowing why
2015-02-26T03:37:51 < gxti> i can't really say i think highly of someone who only connects the fire suppression when the inspector comes.
2015-02-26T03:37:58 < gxti> it sounds like gross incompetence to me.
2015-02-26T03:38:05 < kakeman> so you fill server rooms with nitrogen?

2015-02-26T03:38:50 < kakeman> what if someone is inside server rooms?
2015-02-26T03:39:00 < gxti> you can flood them with CO2 to put the fire out but that's not a gas that "kills fire", it just snuffs out the oxygen. THAT would kill you if you stuck around. halon won't unless you're there for a long time.
2015-02-26T03:39:24 < kakeman> halon?

2015-02-26T03:47:40 < Getty> its all SNOW..... but there is "yellowsnow" for snow that is yellow

2015-02-26T04:05:34 < zyp> in norway, english is mandatory as a second language, and unless you take a vocational path through high school you likely have to do a third language too
2015-02-26T04:05:51 < emeb> zyp: at what age is english started?
2015-02-26T04:06:04 < zyp> young enough that I don't remember
2015-02-26T04:06:23 < emeb> yeah - I didn't start taking other languages until I was 15
2015-02-26T04:06:48 < emeb> except German, which I was speaking fairly fluently at age 4 and then not much after.
2015-02-26T04:06:51 < Getty> in germany we even have english information in bus and train, for those of you who dont know

2015-02-26T04:13:25 < emeb> zyp: Well, from a linguistic standpoint it was mind-expanding to hear the swedish and correlate with the subtitles.
2015-02-26T04:13:35 < emeb> The movie itself - eh. OK I guesss.
2015-02-26T04:13:44 < zyp> the american one was fairly good, even after reading the book
2015-02-26T04:14:04 < emeb> I haven't read the book. The story was suitably twisty.
2015-02-26T04:14:22 < zyp> not the best one to watch on an airplane with other people around me though, some of the scenes were… yeah

2015-02-26T04:15:10 < zyp> I can recommend the book
2015-02-26T04:15:45 < emeb> did they film it in sweden or did they move the action to the US?

2015-02-26T04:17:42 < zyp> any more luck?
2015-02-26T04:18:36 < emeb> zyp: I had a reset strap set up differently from the Waveshare circuit
2015-02-26T04:18:46 < emeb> so it was coming up in a powered-down state.
2015-02-26T04:18:58 < emeb> fixing that helped some, but there are still issues.
2015-02-26T04:19:40 < emeb> I can see that the SMI is working - the software reset works
2015-02-26T04:19:56 < emeb> but then it hangs waiting for the link to come up, even when a cable is present.
2015-02-26T04:20:31 < zyp> well, if SMI is up, I guess you could override any other strap
2015-02-26T04:21:04 < emeb> I could have overriden the power-down too, but I'm taking baby steps in the software side.
2015-02-26T04:21:34 < emeb> AFAICT mine is set up exactly the same as the Waveshare now, but things aren't working the same.
2015-02-26T04:22:19 < emeb> Well, actually there is one difference in the way the regulator is strapped.
2015-02-26T04:22:34 < emeb> the Waveshare circuit violates the MFG's data sheet

2015-02-26T04:23:22 < emeb> uses the status LEDs as straps.
2015-02-26T04:23:39 < zyp> hmm, I get toner for laser printers instead of a datasheet
2015-02-26T04:24:00 < emeb> sorry LAN8720A

2015-02-26T04:24:22 < zyp> well, microchip nowadays
2015-02-26T04:24:25 < emeb> yep
2015-02-26T04:24:45 < emeb> if the LEDs are source to gnd that's one way, sink from VDD that's another.
2015-02-26T04:24:58 < emeb> and it automatically inverts as required.
2015-02-26T04:25:04 < zyp> oh, that's neat
2015-02-26T04:25:09 < emeb> yeah
2015-02-26T04:25:25 < emeb> but Waveshare didn't do the LED setup as per the datasheet

2015-02-26T04:27:18 < emeb> well the strap for disabling the on-chip regulator requires LED sink from VDD with a 10k bypass around the LED.
2015-02-26T04:27:27 < emeb> but they left off the bypass resistor
2015-02-26T04:27:37 < emeb> so it thinks the LED is sink to gnd.
2015-02-26T04:28:18 < emeb> but the LED status is correct - flashes as expected, and the regulator appears to work right.
2015-02-26T04:28:34 < emeb> so I'm confused.
2015-02-26T04:29:00 < emeb> on my board I did it as per the datasheet to enable the regulator. My regulator works, but the chip doesn't detect link.
2015-02-26T04:30:08 < zyp> well, Vf on the led at a very small current will be pretty small, right?
2015-02-26T04:30:40 < zyp> might be enough to pull it over the sample point

2015-02-26T04:35:36 < zyp> do you have separate transformers or a magjack?
2015-02-26T04:36:28 < emeb> only other difference is my board uses a J00-0045NL jack instead of the one that Waveshare used.

2015-02-26T05:36:40 < dongs> or are those all random contracts
2015-02-26T05:36:49 < emeb_mac> dongs: sure, and some small contracts
2015-02-26T05:36:56 < dongs> that = employement, no?
2015-02-26T05:36:56 < emeb_mac> but it's not like full-time
2015-02-26T05:36:58 < dongs> ah
2015-02-26T05:37:11 < emeb_mac> and the audio/synth stuff is small potatos
2015-02-26T05:37:29 < emeb_mac> lots of work for maybe royalties

2015-02-26T05:38:46 < emeb_mac> make a heavy investment in french drone sales
2015-02-26T05:39:07 < dongs> thats funny, i've had a bunch of french asking me for drone trash
2015-02-26T05:39:08 < dongs> not sure why
2015-02-26T05:39:26 < emeb_mac> drones over paris yesterday. got 'em all wound up
2015-02-26T05:39:31 < dongs> lulz
2015-02-26T05:39:37 < dongs> good thing most of these guys paid already
2015-02-26T05:39:42 < dongs> :D
2015-02-26T05:39:45 < emeb_mac> they'll probably ban 'em
2015-02-26T05:45:27 < zyp> I can make a flipbook-app full of Laurenceb's code and sell it as a headache simulator
2015-02-26T05:45:57 < emeb_mac> now that's thinking out of the box

2015-02-26T06:54:47 < dongs> this shit has a 100mhz 80186 in it
2015-02-26T06:55:47 < emeb_mac> sweet!
2015-02-26T06:56:00 < zyp> what, were they that fast?
2015-02-26T06:56:12 < emeb_mac> that's like 1990 stuff right?
2015-02-26T06:56:14 < dongs> they were that fast in at least 2004

2015-02-26T07:05:55 < dongs> In 2000 VAutomation released the Turbo186.  This was an even faster core, compatible with the Intel 80C186 (the V186 was based on the 80186).  At 0.35u and 3.3V speeds over 80MHz were possible.

2015-02-26T07:08:24 < emeb_mac> ds2: not your idea of fun?
2015-02-26T07:09:05 < ds2> emeb_mac: brought up 2 different GMII PHY on a BBB related design... very irritating bugs
2015-02-26T07:09:14 < zyp> uh, MDIO is one of the most straight forward things I've touched
2015-02-26T07:09:28 < ds2> MDIO by itself is no worse then I2C
2015-02-26T07:09:40 < emeb_mac> well, GMII is probably pretty bleeding-edge
2015-02-26T07:09:44 < ds2> but as far as being able to use that to diag the rest of the PHY, it is an exercise in frustration
2015-02-26T07:09:56 < emeb_mac> this is just bog-std 10/100 stuff
2015-02-26T07:09:59 < zyp> sounds like a bad phy
2015-02-26T07:10:16 < ds2> to be fair, it was a Marvell unit :D
2015-02-26T07:10:23 < emeb_mac> there you go

2015-02-26T07:11:13 < ds2> to be fair, they have some "interseting" features
2015-02-26T07:11:15 < emeb_mac> super special sekrit stuff!
2015-02-26T07:11:35 < dongs> one of their features is losing business
2015-02-26T07:11:48 < ds2> you are confused
2015-02-26T07:11:53 < emeb_mac> heh
2015-02-26T07:11:55 < ds2> losing business is prefectly fine
2015-02-26T07:12:12 < ds2> it is losing net revenue that is a problem
2015-02-26T07:12:34 < dongs> just charge businesses they havent lost yet, more
2015-02-26T07:12:43 < dongs> then they will lose those, too
2015-02-26T07:13:20 < ds2> you don't always want a lot of customers. you just want 1 customer that will pay you infinite amount of money indefinitely :D
2015-02-26T07:14:17 < zyp> yeah, then have fun when they go out of business
2015-02-26T07:14:26 < ds2> preferably for doing nothing and delivering nothing
2015-02-26T07:15:11 < gxti> they're not going to go out of business because ##stm32 can't buy chips
2015-02-26T07:15:38 < zyp> I'm talking about the customer
2015-02-26T07:15:45 < emeb_mac> these are not the customers you're looking for
2015-02-26T07:15:53 < emeb_mac> go about your businesss
2015-02-26T07:15:56 < emeb_mac> move along
2015-02-26T07:16:07 < ds2> buying those PHY isn't that hard
2015-02-26T07:16:11 < ds2> it is getting the damn docs
2015-02-26T07:16:17 < emeb_mac> yep
2015-02-26T07:17:26 < ds2> emeb_mac: is the ethernet working?
2015-02-26T07:17:59 < emeb_mac> ds2: not yet
2015-02-26T07:18:10 < emeb_mac> no trouble talking to the phy via SMI
2015-02-26T07:18:21 < zyp> ds2, no, emeb's cable isn't plugged completely into the RJ45 socket
2015-02-26T07:18:23 < emeb_mac> but the phy won't recognize the cable is attached
2015-02-26T07:18:40 < ds2> what is on the other end?
2015-02-26T07:18:43 < ds2> a switch?
2015-02-26T07:19:51 < emeb_mac> just a hub to my router
2015-02-26T07:20:10 < emeb_mac> but I can swap the cable to another STM32 with the same type of PHY and it works
2015-02-26T07:20:32 < emeb_mac> so it's something in my board design that's mungled
2015-02-26T07:20:38 < ds2> I personally find debugging against a modern hub to be frustrating at best
2015-02-26T07:21:04 < ds2> xover cable to a laptop and manually iterate through the modes is more productive
2015-02-26T07:21:23 < ds2> does this PHY tell you cable status and signal quality?
2015-02-26T07:21:45 < zyp> uh, if you can't set modes on your hub, it's not modern enough
2015-02-26T07:22:33 < ds2> even with Cisco gear, only a few of them lets you have the granularity of laptop
2015-02-26T07:22:35 < emeb_mac> ds2: this is an old hub - nothing fancy
2015-02-26T07:22:53 < ds2> things like autoMDX can through you for a loop
2015-02-26T07:23:06 < emeb_mac> and the PHY doesn't give a lot of feedback on signal qual

2015-02-26T07:24:33 < emeb_mac> yes - that

2015-02-26T07:25:44 < emeb_mac> unmarked. :P
2015-02-26T07:26:15 < zyp> have you inspected all the solder joints? are you sure they are good?
2015-02-26T07:26:45 < emeb_mac> I've beeped out all the connections to the PHY and checked for shorts too
2015-02-26T07:28:43 < emeb_mac> solder joints on the resistors and magjack look clean
2015-02-26T07:30:42 < emeb_mac> interestingly the magjack coils show up as shorts - I assume because the DC resistance is low.

2015-02-26T10:38:21 < jpa-> depends on your apb1/apb2 clock frequency
2015-02-26T10:39:38 < ehsan> APB1 42Mhz & APB2 168MHz. and i don't know TIM1 use which...
2015-02-26T10:40:46 < jpa-> reference manual RCC section, see which config register (APB1ENR / APB2ENR) it belongs to
2015-02-26T10:41:06 < jpa-> but neither of those is divisible by 10MHz so you cannot have 100ns exactly
2015-02-26T10:42:02 < qyx_> you could clocl the stm at 160MHz maybe

2015-02-26T15:00:27 < jpa-> how do you not?
2015-02-26T15:00:32 < jpa-> just set the dividers?
2015-02-26T15:00:55 < dongs> ya this always confuses me
2015-02-26T15:00:59 < dongs> do i run timer at like 24mhz
2015-02-26T15:01:11 < dongs> and set period to 10k or someshit?
2015-02-26T15:01:18 < Lux> sure
2015-02-26T15:01:19 < jpa-> that works and is simple
2015-02-26T15:01:20 < qyx_> there is a prescaler
2015-02-26T15:01:29 < qyx_> or period
2015-02-26T15:01:36 < jpa-> it doesn't matter what is the exact ratio between prescaler vs. period
2015-02-26T15:02:33 < qyx_> which reminds me, setting a prescaler value on tim3 works but it doesn't work on tim2, it always counts fullspeed
2015-02-26T15:02:52 < dongs> huh
2015-02-26T15:02:54 < dongs> on waht stm?
2015-02-26T15:03:04 < qyx_> f401 with libopencm3
2015-02-26T15:03:15 < qyx_> https://pastee.org/34cjc
2015-02-26T15:03:20 < qyx_> this doesn't work
2015-02-26T15:03:37 < qyx_> tim2 correctly counts 32bits at 16MHz
2015-02-26T15:03:41 < qyx_> the 5 prescaler is simply ignored
2015-02-26T15:03:47 < qyx_> if i replace tim2 with tim3
2015-02-26T15:03:54 < dongs> so prescalre is 24-1?
2015-02-26T15:03:54 < qyx_> and uint32_max with uint16_max
2015-02-26T15:03:57 < dongs> or 3-1
2015-02-26T15:04:00 < dongs> for 24mhz
2015-02-26T15:04:07 < dongs> my currenty one is 72-1 for 1MHz
2015-02-26T15:04:13 < qyx_> yes
2015-02-26T15:04:21 < qyx_> i run f401 at 16MHz
2015-02-26T15:04:28 < qyx_> thats why there is 15
2015-02-26T15:04:43 < qyx_> tim3 runs at 1MHz, but tim2 at 16MHz
2015-02-26T15:04:51 < dongs> but all Fx timers have prescalers

2015-02-26T16:05:11 < qyx_> i heard that on microsd it is optional

2015-02-26T16:13:16 < trepidaciousMBR> Yeah it's confusing - looking at the spec (briefly) SPI is in there, and it doesn't say optional (it doesn't say mandatory, but it doesn't say SDIO is mandatory either)
2015-02-26T16:13:40 < trepidaciousMBR> The Wiki page USED to say it was optional on microSD, but with "citation needed", and now it doesn't say that any more
2015-02-26T16:14:08 < trepidaciousMBR> So basically everything authoraitative seems to say SPI is supported...
2015-02-26T16:14:15 < trepidaciousMBR> But there's still some doubt around it ;)
2015-02-26T16:14:40 < trepidaciousMBR> E.g. here http://www.embeddedrelated.com/groups/lpc2000/show/46585.php
2015-02-26T16:15:08 < trepidaciousMBR> But that guy says maybe the cards just aren't following the spec, which seems completely possible, I can imagine people manufacturing SD cards with nearly anything wrong with them ;)

2015-02-26T16:26:24 < trepidaciousMBR> Yeah I think SPI is really meant to be supported, probably there are "You're best digital fun-life micro-5D" cards out there that don't support it, they're probably also formatted as 32GB while having 640KB of actual flash fitted.

2015-02-26T18:01:45 < dongs> why does that shit start off with sounds of someone fapping
2015-02-26T18:02:17 < Getty> Steffanx: well its illegal production, thats why they get sued now ;)

2015-02-26T18:39:38 < zyp> cute
2015-02-26T18:40:14 < zyp> maybe that's how I should do overvoltage protection on the F4 board, just pick a regulator that can handle three times the nominal input voltage
2015-02-26T18:40:39 < karlp> yeah, I've saved that for myself too :)
2015-02-26T18:40:46 < dongs> laff
2015-02-26T18:40:55 < karlp> we support 15V in now, for 12V supplies, but people want to use 24v power
2015-02-26T18:41:10 < karlp> and that's not working on the little 3v3 linear we have now :)
2015-02-26T18:41:57 < zyp> this shit that my board plugs into is protecting itself in every way with zener diodes and shit, but my board is fed 12V from before the protection circuitry

2015-02-26T18:50:10 < zyp> new video of zano not flying
2015-02-26T18:50:40 < dongs> zyp, did y ou watch it
2015-02-26T18:50:48 < zyp> just started
2015-02-26T18:53:06 < owl-v-> stationary... in a box... tilting... a bit.
2015-02-26T18:53:11 < dongs> @Ron Risman I totally agree. Seriously after all this time Zano makers dont have not even one video with this thing flying? We got videos about everything, almost got videos what time executives pee, but no video of ZANO flying. Almost 1,5 month passed since the ZANO was backed and there is NOT A SINGLE VIDEO of it on the air.

2015-02-26T18:58:49 < dongs> no, more like shit
2015-02-26T18:59:07 < dongs> advertised features: full autonomy (gps, obstacle avoidance, follow-me, etc)

2015-02-26T19:01:18 < owl-v-> that pic32 better be pic32MZ

2015-02-26T19:01:26 < dongs> but its irrelevant
2015-02-26T19:01:36 < owl-v-> 200Mhz
2015-02-26T19:01:42 < Laurenceb> they need ambarella or something

2015-02-26T19:09:54 < Laurenceb> root a gopro and run a drone controller over the wifi

2015-02-26T19:10:20 < Laurenceb> a drone is 10 times easier than a good camera
2015-02-26T19:10:30 < Laurenceb> theres shit tons of work gone into gopro hero range

2015-02-27T03:41:39 < emeb> for giggles I pulled off the 50ohm load resistors - R301 thru R304 in that pic
2015-02-27T03:41:45 < emeb> and now no shorts
2015-02-27T03:43:45 < qyx_> they have no markings
2015-02-27T03:45:02 < emeb> true - but they all measure 50ohms as expected
2015-02-27T03:51:58 < emeb> fresh resistors down - now there's 100 ohms across the diff pairs. better.
2015-02-27T03:52:30 < zyp> heh
2015-02-27T03:53:21 < emeb> I have no fscking clue what was going on there.
2015-02-27T03:53:34 < emeb> if there were bridges I couldn't see them

2015-02-27T04:01:03 < emeb> interestingly though, one of the LEDs on the magjack isn't lighting up
2015-02-27T04:01:13 < ds2> some phys could have detected that
2015-02-27T04:01:24 < emeb> ds2: ya
2015-02-27T04:04:37 < emeb> gonna dump out the PHY regs to check what it thinks the link is doing.
2015-02-27T04:06:44 < ds2> does this PHY have multiple pages?
2015-02-27T04:07:27 < zyp> wonder how those cable test functions will do when the problem is located between the phy and the transformer and not on the other side of the transformer
2015-02-27T04:07:54 < zyp> would probably still report a short, I guess
2015-02-27T04:08:08 < ds2> zyp: you get "interesting" nonsensical results that you have to interpret
2015-02-27T04:08:28 < ds2> which PHYs have cable test?

2015-02-27T04:24:21 < zyp> http://www.micrel.com/_PDF/Ethernet/datasheets/KSZ8864CNX_RMNUB.pdf <- this also looks like a fun part
2015-02-27T04:26:00 < emeb> for putting multiple hosts on one board?
2015-02-27T04:26:51 < zyp> well, it supports VLAN tag insertion, so you can have two ports, and traffic to/from the MCU tagged with which port it came from/goes to
2015-02-27T04:27:04 < zyp> which kinda gives you multiple interfaces on a single MAC
2015-02-27T04:27:21 < owl-v-> looks like it's a fun TCP/IP packet sniffer
2015-02-27T04:27:53 < zyp> assuming it can do port mirroring
2015-02-27T04:28:28 < zyp> it also does RSTP, so you could use the two ports as a redundant network
2015-02-27T04:29:13 < zyp> i.e. you could connect the devices in a loop, so that you'll have redundancy if the loop is broken somewhere
2015-02-27T04:29:36 < zyp> or simply use it for chaining devices without requiring an external switch
2015-02-27T04:29:38 < ds2> it runs STP in HW?
2015-02-27T04:30:03 < zyp> it's a full switch chip
2015-02-27T04:30:56 < gxti> of course with stuff like STP you know it's running a little 8051 core in there or something, but it's not your problem
2015-02-27T04:31:10 < zyp> yeah
2015-02-27T04:31:57 < ds2> wonder if there are buffer overflows in that STP implementation
2015-02-27T04:32:09 < owl-v-> so... it's good for two processors on one board?
2015-02-27T04:32:19 < zyp> that too
2015-02-27T04:33:40 < emeb> Well, knock off debug for the night. End with a success...

2015-02-27T08:59:55 < PeterM> nope nvm they moved the pinout around on it
2015-02-27T09:01:03 < dongs> nope its all fucking gay pinout

2015-02-27T09:12:39 < dongs> at 12, its unusable
2015-02-27T09:12:42 < dongs> at 16V its ok
2015-02-27T09:12:48 < dongs> but my richteks on the rest of hte boards are 18V masx
2015-02-27T09:15:57 < PeterM> hmm...
2015-02-27T09:16:10 < dongs> anyway
2015-02-27T09:16:22 < dongs> at 12V, its just getting shitty by Rsense and garbage rdson of the fet
2015-02-27T09:16:34 < dongs> and inductor is getting ~4.1A where its only rated for 3
2015-02-27T09:16:58 < dongs> but at 24V, its like 2.xA @ inductor, and fet/rsense has less stuff going through it
2015-02-27T09:17:02 < dongs> so at 24V I think their parts work oK
2015-02-27T09:18:12 < PeterM> fet is probably OK then, inductor is probably saturating and smashign the fet
2015-02-27T09:19:11 < dongs> so for next spin im just gonna put like 5A inductor on there
2015-02-27T09:19:14 < dongs> and 3W rsense
2015-02-27T09:19:20 < dongs> instead of 1W
2015-02-27T09:20:00 < dongs> this way if one of those 3 things is trash, i dont have to figure out which one
2015-02-27T09:20:43 < PeterM> i doubt it s the sense resistor - its probably just taking a thrashing because the inductor is saturating so current is skyrocketing
2015-02-27T09:22:49 < dongs> http://www.dx.com/p/usb-led-module-291219#.VPAGh_nQWck yessssssssssssssssssssssssssss
2015-02-27T09:23:50 < PeterM> not sure if trolling or legit
2015-02-27T09:24:25 < dongs> that must work extra good with metal-shield USB sockets
2015-02-27T09:25:06 < PeterM> they're handy if you've got one of those single 18650 powerbanks, but for $1.70 thats pricy. im guessing the contact height difference due to soldermask only jsut saves them

2015-02-27T09:30:38 < PeterM> no need for actual numbers, so crank the gain on your scope lal the way up just make sure the wave doesnt look like this http://i.stack.imgur.com/9Fu2j.jpg
2015-02-27T09:31:07 < dongs> ^ that graph for voltage across rsense?

2015-02-27T09:31:56 < dongs>  right
2015-02-27T09:32:38 < PeterM> i fuckign hate inductor manufactuerers who are like Rated current: 4A saturation current: 2.5A
2015-02-27T09:32:54 < PeterM> its liek "are you fucking shittingme?"
2015-02-27T09:33:34 < qyx_> but rated is average at specified temp rise
2015-02-27T09:33:50 < qyx_> uh
2015-02-27T09:34:04 < qyx_> yes, not the other way around
2015-02-27T09:34:25 < PeterM> or their rated to run art 30% inductance loss, and their datasheet spec for saturation is 10% inductance loss

2015-02-27T09:39:33 < PeterM> are you using the ground clip or you using the small springy point?
2015-02-27T09:40:15 < PeterM> cause most of that shit looks like the long ground lead
2015-02-27T09:40:17 < dongs> springy point? no im just measureing one end of rsense (gnd pour) to the ot her end
2015-02-27T09:41:30 < PeterM> i mean on your probe, are you using the black cliplead or the low inductance ground spring

2015-02-27T09:43:16 < dongs> but i am pretty surei odnt
2015-02-27T09:43:31 < PeterM> they'll probably be in the bag that your probes came with with yer scope. cant get a good look at trace with allthat ringing

2015-02-27T10:03:00 < Simon--> (depending on material etc)
2015-02-27T10:03:21 < qyx_> but the controller is current mode, so it turns it out at that point
2015-02-27T10:03:24 < PeterM-Mobile> Depends.  Saturation is an exponential thing
2015-02-27T10:04:23 < PeterM-Mobile> Inductance drops > faster current rise> more current>  more inductance drop > repeat

2015-02-27T10:53:51 < scrts_w> if reverse current is too high

2015-02-27T11:35:24 < pgomes> and by mistake I have overwritten the Demo
2015-02-27T11:35:39 < pgomes> is there a simple way to FLASH it using st-link - I am using MACOSX.

2015-02-27T11:41:59 < scrts_w> there is
2015-02-27T11:42:03 < scrts_w> but in MAC...
2015-02-27T11:42:13 < scrts_w> you'd better switch to linux for development then
2015-02-27T11:42:24 < superbia> nice one scrts_w
2015-02-27T11:44:01 < pgomes> I would say that MAC and LInux would be using st-link no ?
2015-02-27T11:44:29 < scrts_w> st-link is an adapter
2015-02-27T11:44:32 < scrts_w> you need software for it
2015-02-27T11:44:37 < pgomes> the software
2015-02-27T11:44:41 < pgomes> sorry
2015-02-27T11:45:04 < pgomes> I mean https://github.com/texane/stlink
2015-02-27T11:45:16 < pgomes> to flash and gdb the stuff for MAC and LInux
2015-02-27T11:45:24 < karlp> if you're just getting started, I highly recommend you do not begin to use texane/stlink.
2015-02-27T11:45:49 < karlp> if you're just getting started, openocd's stlink hardware support is better supported and more reliable.
2015-02-27T11:46:02 < karlp> texane/stlink existed first and did a wonderful job for it's time.
2015-02-27T11:46:06 < pgomes> even for Linux/MAC ?
2015-02-27T11:46:33 < karlp> if you're in a position that you want to use texane/stlink, I'm assuming you're on linux/mac already.
2015-02-27T11:46:45 < pgomes> yes
2015-02-27T11:46:57 < karlp> so, "even for linux/mac?" is irrelevant
2015-02-27T11:47:02 < pgomes> sorry ...

2015-02-27T12:02:52 < dongs> i tihnk thats why i discarded it

2015-02-27T13:42:45 < Laurenceb> this is perplexing
2015-02-27T13:43:07 < dongs> UK has one of the highest stupid concentrations, i wonder if Laurenceb had something to do with that
2015-02-27T13:43:22 < Laurenceb> ive collected several minutes of data from my L3GD20 with saleae
2015-02-27T13:43:25 < Laurenceb> loldongs

2015-02-27T13:48:22 < karlp> const char **dst is a poitner to a const pointer? so I can put a pointer to a const char * in it?
2015-02-27T13:48:29 < karlp> stupid double redirection
2015-02-27T13:49:16 < jpa-> can also be a pointer to an array of const char *'s
2015-02-27T13:50:00 < jpa-> considering that it is called 'dst' and the actual pointer is const, i would expect the function to give you a pointer back
2015-02-27T13:50:18 < karlp> think I need to suck this and see.
2015-02-27T13:50:43 < karlp> I have a const char *, I want to parse that into to a reusable function that pulls a string out of json, using a function that also returns a const char *

2015-02-27T14:20:57 < Laurenceb> ive written a script to search through the dumped data

2015-02-27T14:21:19 < Laurenceb> hmm
2015-02-27T14:21:36 < Laurenceb> i cant see how it could
2015-02-27T14:21:57 < Laurenceb> but im running out of places where the bug could be :-S
2015-02-27T14:22:12 < specing> Laurenceb: rewrite your code in Ada and let the compiler tell you where the error is
2015-02-27T14:22:21 < Laurenceb> heh
2015-02-27T14:22:52 < specing> Im very serious
2015-02-27T14:23:21 < dongs> < specing> Laurenceb: rewrite your code in AIDS and let the compiler tell you where the error is
2015-02-27T14:23:24 < dongs> ftfy
2015-02-27T14:23:36 < dongs> tho im not sure if Laurenceb could be any more aids
2015-02-27T14:23:41 < specing> all the array accesses have runtime bounds checking (unless you tell it not to)
2015-02-27T14:23:42 < dongs> er Laurenceb code
2015-02-27T14:23:51 < dongs> specing: its not that
2015-02-27T14:23:56 < Laurenceb> specing: yeah ada is nice
2015-02-27T14:24:09 < specing> additionally, if it can determine that you did something dumb at compile time, it will tell you
2015-02-27T14:24:10 < dongs> Laurenceb: are all teh crap arrays youre touching wiht threads marked as volatile?
2015-02-27T14:24:18 < Laurenceb> yeah
2015-02-27T14:24:23 < specing> And Ada can do that
2015-02-27T14:24:32 < specing> plus Ada has built-in threading
2015-02-27T14:24:37 < Laurenceb> i can also check the timing with saleae
2015-02-27T14:24:43 < Laurenceb> and its spot on
2015-02-27T14:25:01 < Laurenceb> so i2c is started, then completes in a few hundred µs
2015-02-27T14:25:08 < Laurenceb> its not read for another 10ms
2015-02-27T14:25:15 < Laurenceb>  - the data array
2015-02-27T14:25:40 < Laurenceb> also that wouldnt explain how the data array glitches by shifting one byte out of alignment
2015-02-27T14:26:16 < Laurenceb> that would give +-256lsb errors

2015-02-27T16:34:30 < green1> hello,
2015-02-27T16:34:56 < green1> is there a simplified library for  stm32f2xxx ?
2015-02-27T16:35:24 < green1> stm Std peripheral library is  complex to me
2015-02-27T16:35:54 < green1> http://stm32f4-discovery.com/2014/05/all-stm32f429-libraries-at-one-place/
2015-02-27T16:35:57 < specing> write your own library ;)
2015-02-27T16:36:10 < green1> :(
2015-02-27T16:36:24 < green1> specing:
2015-02-27T16:36:30 < green1> too complex it is
2015-02-27T16:36:50 < green1> above library provide stm32f4 simplied library using SPL.
2015-02-27T16:37:01 < green1> but, i looking for stm32f2xx
2015-02-27T16:39:39 < green1> is stm32f2xx and stm32f4xx peripheral interface registers competible ?
2015-02-27T16:40:09 < specing> green1: try? :D
2015-02-27T16:40:59 < green1> i find it hard to remember more than 2 sentences
2015-02-27T16:41:42 < green1> my RAM get cleared every minute
2015-02-27T16:41:43 < green1> lol
2015-02-27T16:41:57 < green1> i will have to go through same page all the day
2015-02-27T16:42:18 < specing> < green1> i find it hard to remember more than 2 sentences
2015-02-27T16:42:56 < specing> I don't think the problem is in the standard libraries...
2015-02-27T16:43:48 < green1> do u mean,  SPL make hardware look over complex ?
2015-02-27T16:44:22 < Laurenceb> hmm
2015-02-27T16:44:33 < Laurenceb> i seem to have solved my L3GD20 issues
2015-02-27T16:46:42 < Laurenceb> looks like it was related to some screwy memcpy :P

2015-02-27T20:14:08 < green1> in a mood to get shot
2015-02-27T20:15:37 < gxti> it's just syntax naming it as a member of that struct
2015-02-27T20:16:16 < gxti> i don't think it's valid anywhere in C, it's a c++ thing, but you still see it in compiler output or whatever where it needs to tell you both which member and what struct it belongs to
2015-02-27T20:22:32 < green1> i see thank you.
2015-02-27T20:23:06 < green1> stm32f2xxx SPL User manual says :
2015-02-27T20:23:08 < green1> Thanks to the Standard Peripheral Library, low-level implementation details are transparent so that
2015-02-27T20:23:08 < green1> reusing code on a different MCU requires only to reconfigure the compiler. As a result, developers can
2015-02-27T20:23:08 < green1> easily migrate designs across the STM32 series to quickly bring product line extensions to market
2015-02-27T20:23:08 < green1> without any redesign.
2015-02-27T20:24:36 < green1> does this mean, source code using SPL valid as long as the addressing peripheral available in selected MCU , in stm32 range ?
2015-02-27T20:25:29 < green1> source code is valid ?
2015-02-27T20:25:30 < zyp> assuming the peripheral is identical
2015-02-27T20:25:49 < green1> does it ?
2015-02-27T20:25:52 < zyp> which isn't always the case in practice, since there are several generations of each peripheral
2015-02-27T20:26:09 < green1> i see,
2015-02-27T20:27:02 < emeb> any HTML experts here?
2015-02-27T20:27:34  * Tectu points to Steffanx :P
2015-02-27T20:27:47 < zyp> emeb, I can hardly call myself that, but that doesn't necessarily imply that I can't answer your question
2015-02-27T20:28:07 < emeb> zyp: I've got the demo webserver for the STM32F4 up & running on my board
2015-02-27T20:28:22 < emeb> there are 3 pages - a top intro page, an LED page and an ADC page.
2015-02-27T20:28:30 < emeb> the top and LED pages work fine on my board.
2015-02-27T20:28:38 < emeb> All three work fine on the F4 Discovery
2015-02-27T20:28:52 < emeb> but on my board the ADC page renders as text only on my browser.
2015-02-27T20:29:19 < emeb> If I save that text in a file on my desktop then load it in the same browser it renders fine.
2015-02-27T20:29:30 < zyp> sounds like the http server doesn't send a mime type so the browser have to guess, and guesses wrong in one case
2015-02-27T20:29:37 -!- superbia [~superbia@unaffiliated/superbia] has joined ##stm32
2015-02-27T20:29:48 < zyp> the mime type is part of the http headers, not the html
2015-02-27T20:29:54 < emeb> aha
2015-02-27T20:30:14 < zyp> when you save the file, there's no http headers, so browser uses filename extension instead
2015-02-27T20:30:38 < emeb> should try a different browser to see if it guesses differently
2015-02-27T20:31:16 < green1> zyp:  i'm happy, at least i have to learn only once a purticular module, with that knowledge i can use any stm32 MCU. glad to got to know it.
2015-02-27T20:31:31 < emeb> nope - firefox does same thing.
2015-02-27T20:32:21 < green1> i was afraid that, i would have to  study all if i change MCU family.
2015-02-27T20:34:03 < zyp> emeb, I'd take a look if you were able to forward a port to it or something ;)
2015-02-27T20:35:01 < emeb> zyp: I'll see if I can...
2015-02-27T20:35:03 < qyx_> zyp @ nsa mode
2015-02-27T20:36:38 < emeb> zyp: does this work? http://68.104.219.12/
2015-02-27T20:37:05 < zyp> doesn't appear to
2015-02-27T20:37:47 < emeb> hmm... works when I try.
2015-02-27T20:38:05 < emeb> wonder what I missed in the router...
2015-02-27T20:38:35 < scrts> doesn't work for me
2015-02-27T20:38:38 < zyp> maybe your ISP is an asshole and blocks incoming connections on port 80
2015-02-27T20:38:52 < emeb> could try 8080 I guess...

2015-02-27T20:39:59 < zyp> okay, 8080 works now
2015-02-27T20:40:42 < zyp> I guess it guesses wrong because the ADC page is .shtml, while the other ones are .html
2015-02-27T20:41:04 < emeb> Steffanx: that content-type is in there

2015-02-27T20:41:41 < Steffanx> my browser says its text/plain
2015-02-27T20:42:13 < zyp> yep
2015-02-27T20:42:19 < zyp> HTTP/1.0 200 OK
2015-02-27T20:42:19 < zyp> Server: lwIP/pre-0.6 (http://www.sics.se/~adam/lwip/)
2015-02-27T20:42:20 < zyp> Content-type: text/plain
2015-02-27T20:42:31 < emeb> so that comes from the HTTP header?
2015-02-27T20:42:36 < zyp> yeah
2015-02-27T20:42:38 < emeb> and not from inside the file
2015-02-27T20:42:55 < gxti> indeed.
2015-02-27T20:42:56 < zyp> correct
2015-02-27T20:43:03 < emeb> so I need to figure out where the demo code assigns the HTTP info
2015-02-27T20:43:08 < gxti> it works when you save it because the saved file has no headers, so the browser just guesses from content or filename
2015-02-27T20:43:16 < zyp> so it's not even the browser that's guessing wrong, the server is reporting it wrong
2015-02-27T20:43:22 < emeb> ya
2015-02-27T20:45:26 < emeb> digging thru the httpd.c code - looks like it defaults to plain when it doesn't find the filetype in a table.
2015-02-27T20:45:34 < emeb> need to find that table
2015-02-27T20:46:48 < zyp> or just change from .shtml to .html :p
2015-02-27T20:47:40 < emeb> dumb question: what's the difference between shtml and html?
2015-02-27T20:48:19 < gxti> http://en.wikipedia.org/wiki/Server_Side_Includes
2015-02-27T20:48:32 < gxti> by the time the browser sees it, nothing
2015-02-27T20:49:30 < emeb> aha - but that ADC page has a field in it that the server changes on the fly
2015-02-27T20:49:36 < zyp> I don't think SSI have even been a thing the last decade or two :p
2015-02-27T20:49:52 < gxti> i bet we'd both be surprised, zyp
2015-02-27T20:50:01 < Steffanx> except when you're using lwiphttpd
2015-02-27T20:50:04 < zyp> I don't count weirdos
2015-02-27T20:50:16 < gxti> there's a lot of ancient shit still in use
2015-02-27T20:50:27 < gxti> emeb: well, does it rely on a particular file extension?
2015-02-27T20:51:07 < Steffanx> it seems the ssi part is where it fails, because you can see the code still in the html
2015-02-27T20:51:10 < emeb> need to study the code in more detail to figure that out

2015-02-27T21:40:44 < kakeman> do you know solutions for external connection esd protection + prolonged misconnection to higher voltage input? apart from resistor+tvs setting
2015-02-27T21:42:31 < kakeman> to reduce cons of resistor+tvs setting
2015-02-27T21:43:47 < qyx_> what is "voltage input"?
2015-02-27T21:43:59 < kakeman> let say logic level 3v3 and voltage input level 35volts
2015-02-27T21:44:55 < kakeman> lets say you misconnect them
2015-02-27T21:45:08 < qyx_> for low speed logic its usually ok to use resistor and two diodes/zener/tvs
2015-02-27T21:45:22 < qyx_> for dc power input you can use ptc & zener or tvs
2015-02-27T21:45:31 < qyx_> or dedicated protection ic with mosfet
2015-02-27T21:45:40 < kakeman> hey
2015-02-27T21:45:45 < kakeman> I can use ptc there

2015-02-27T22:52:25 < PaulFertser> Curious. I wonder if it really helps with anything in real life environments especially taking into account the reliability of the other components and firmware implemented in C.
2015-02-27T22:55:47 < PaulFertser> I think if you need that kind of reliability, just get a controller with hardware ECC RAM. Or several of them and do arbitration with something even more reliable. And provide means to physically power-cycling individual chips in case their power consumption rises too much (which likely indicates a latch-up condition).

2015-02-27T23:04:43 < jpa-> but yeah, i would expect any safety critical system to use Cortex-R or similar with hardware ECC
2015-02-27T23:05:01 < jpa-> the manual duplicate & check then becomes quite useless
2015-02-27T23:07:34 < Green11> you mean, running cortex on external ECC RAM ? via FSMC ? loading program into external ram every reset,
2015-02-27T23:08:00 < Green11> as stm32 has no ECC ram rom  range.
2015-02-27T23:09:33 < Green11> i got the points, paul said..

2015-02-28T00:08:22 < Laurenceb_> ok
2015-02-28T00:08:29 < Laurenceb_> so i send start and get start start
2015-02-28T00:08:41 < Laurenceb_> which causes my L3GD20 to ignore the next byte
2015-02-28T00:09:32 < Laurenceb_> if i put a delay between setting start and loading the address into the data register, the bug goes away
2015-02-28T00:11:39 < zyp> uh, you're not supposed to load the addr into the data register before you get EV5

2015-02-28T00:16:47 < Laurenceb_> so if i just load the addr in the interrupt handler it fails
2015-02-28T00:17:26 < Laurenceb_> if i wait until a few i2c clks after the interrupt handler has been called before entering, it works

2015-02-28T00:18:51 < Laurenceb_> which is described ambiguously in the datasheet
2015-02-28T00:19:05 < Laurenceb_> previously i interpretted it as meaning you had to use stop-start
2015-02-28T00:19:19 < Laurenceb_> but at there is no stop interrupt, that means ~10µs of busy wait

2015-02-28T00:38:40 < pero_p> hi guys. i'm using STMCubeMX to generate code for stm32f407vg micro, i enabled TIM14 and it's global interrupt, and add GPIOC->ODR ^= (1<<13); in interrupt function that should blink an LED, but it not work :(

2015-02-28T03:10:50 < kakeman> there is seperate documentation certainly?
2015-02-28T03:11:34 < qyx_> i came to the conclusion that the documentation can be more easily maintained directly in the code
2015-02-28T03:12:19 < kakeman> yes
2015-02-28T03:12:28 < qyx_> if it is separated, it slowly diverges from the actual featureset because of lazyness
2015-02-28T03:12:42 < qyx_> *i
2015-02-28T03:13:46 < qyx_> so i just started putting all docs (including protocol documentation and "user manual") in the sources

2015-02-28T03:56:56 < qyx_> it has some nice custom formatting tags for pdf

2015-02-28T04:06:42 < dongs> all proper docs are made with adobe indesign or pagemaker

2015-02-28T06:31:15 < zyp> so it's not that easy :p
2015-02-28T06:38:43 < zyp> maybe I could find the .data initialization code during startup and just change the pointer registers
2015-02-28T06:40:19 < emeb_mac> wow - can't dma from flash. weird
2015-02-28T06:40:39 < zyp> well, read protection

2015-02-28T06:43:15 < emeb_mac> just like on bad tv shows - the hard drive is erasing itself!
2015-02-28T06:44:51 < zyp> hmm, no, possibly just bad connection

2015-02-28T06:48:26 < zyp> oh, right
2015-02-28T06:48:40 < zyp> the firmware is in hardfault too
2015-02-28T06:48:55 < zyp> I guess entire flash bus is turned off when debugger connects
2015-02-28T06:52:43 < dongs> sdo
2015-02-28T06:52:44 < dongs> so
2015-02-28T06:52:45 < emeb_mac> aha - tricky
2015-02-28T06:52:46 < dongs> load something in ram
2015-02-28T06:52:53 < dongs> reset into ram code
2015-02-28T06:53:02 < dongs> make some protocol w/ram stuff to slurp firmware
2015-02-28T06:53:45 < zyp> if I'm reading the documentation right, it's also made inaccessible when you're not booting from flash
2015-02-28T06:54:05 < emeb_mac> even trickier
2015-02-28T06:54:07 < dongs> mhm

2015-02-28T06:58:13 < zyp> already? :p
2015-02-28T06:58:19 < emeb_mac> KIDDING
2015-02-28T06:58:56 < emeb_mac> is flash writing disabled until you do a full erase?
2015-02-28T07:00:30 < zyp> probably
2015-02-28T07:01:02 < zyp> enabling read protection also enables write protection on the first four pages or something
2015-02-28T07:01:40 < emeb_mac> right - so you can't take over the vectors
2015-02-28T07:02:05 < zyp> well, I'd erase more than the vectors to rewrite the vector table, which I don't want to do
2015-02-28T07:07:14 < dongs> taking out ROP does mass flash erase
2015-02-28T07:07:18 < dongs> not just few sectors
2015-02-28T07:07:44 < zyp> yeah, assuming you want to turn it off
2015-02-28T07:07:56 < dongs> you mean you can erase without?
2015-02-28T07:08:10 < zyp> what emeb were thinking of was to rewrite the vector table and put in some code to dump the rest of flash
2015-02-28T07:08:11 < dongs> *partial erase
2015-02-28T07:08:19 < zyp> but I don't think so
2015-02-28T07:08:44 < zyp> I think ROP doesn't only block reads, but all access to flash

2015-02-28T14:48:09 < Tectu> what are you guys talking about?
2015-02-28T14:51:31 < trepidaciousMBR> Hey Tectu, I was just looking at using SPI with microSD cards, and I ran into your ChibiOS posting on having problems with 8 out of 10 cards not supporting SPI properly, which sounds kind of worrying?
2015-02-28T14:53:30 < Tectu> trepidaciousMBR, yep it i
2015-02-28T14:53:31 < Tectu> is
2015-02-28T14:53:53 < Tectu> trepidaciousMBR, SPI is (no longer) to be expected to work with newer cards
2015-02-28T14:54:12 < Tectu> trepidaciousMBR, most cards still have the SPI interface as the manufacturer uses it to program the controller inside and do the testing
2015-02-28T14:54:27 < trepidaciousMBR> Tectu: I had a look round the specs and so on, and I couldn't find anything to say that SPI was optional on microSD, are the cards you had a problem with maybe just not really SD compliant?
2015-02-28T14:55:09 < Tectu> trepidaciousMBR, they are claimed to be SD cards. I had 100% genuine cards from major manufacturers such as SanDisk, Kingston, Lexar, Patriot and so on.
2015-02-28T14:55:44 < Tectu> trepidaciousMBR, a friend of mine who actually works in taht business told me that the actual SD standardization (no ideas about versions of those) does not contain SPI interface (anymore?)
2015-02-28T14:56:06 < Tectu> trepidaciousMBR, but I stopped investigating. Since then I always recommend people to use SDIO anyway
2015-02-28T14:56:31 < trepidaciousMBR> Tectu: Ah that's annoying, I was hoping they were just "your happy magic SD card for fun digital life" no-brand cards
2015-02-28T14:57:00 < Tectu> trepidaciousMBR, not at all. I think I even included an image
2015-02-28T14:57:08 < trepidaciousMBR> Tectu: I couldn't find anything about SPI being optional in the simplified SD spec., and the wiki page now says that SPI is always supported, although it apparently used to say it was optional for microSD
2015-02-28T14:57:37 < trepidaciousMBR> I would use SDIO, but in their wisdom ST decided that you can't use DCMI, FSMC and SDIO at the same time
2015-02-28T14:57:50 < trepidaciousMBR> The pins conflict on F437

2015-02-28T14:59:09 < Tectu> trepidaciousMBR, just some of the brands that I tried. As you can see those are all major brands. And I personally bought them all from an official reseller
2015-02-28T14:59:32 < trepidaciousMBR> Tectu: Hm, that would have been my other question, whether they were fake ;)
2015-02-28T14:59:44 < Tectu> trepidaciousMBR, ah, I don't have the other picture anymore. I also had issues with some kingston ones
2015-02-28T14:59:45 < trepidaciousMBR> Tectu: Any chance that SPI was just running too fast, signal quality issues?
2015-02-28T15:00:43 < Tectu> trepidaciousMBR, I have to admint that back the days I did (obviously) not have as many experience as I do today. If you care: I used some STM32F103RB board from ebay (chinese board) for testing. The hardware quality itself was quite good (way above average chinese board quality)
2015-02-28T15:01:47 < trepidaciousMBR> Tectu: I guess I'll have to do some testing myself as well, before I commit to SPI
2015-02-28T15:01:57 < trepidaciousMBR> Tectu: Thanks for the pointers
2015-02-28T15:02:17 < Tectu> trepidaciousMBR, no problems. happy to help.
2015-02-28T15:02:41 < Tectu> trepidaciousMBR, anyway. nowdays I have a huge pile of SD cards in a small box on my desk anyway. But if you design a product that you want to sell I'd be rather careful
2015-02-28T15:03:09 < Tectu> trepidaciousMBR, I remember seeing some devices that a friend of me desgined where the manual stated a list of "supported SD cards"
2015-02-28T15:03:11 < trepidaciousMBR> Tectu: Yeah I want to be confident we can always get SPI compatible SD cards
2015-02-28T15:03:25 < Tectu> I asked him wtf once and he told me that they were forced to use SPI mode (similar reasons that you have) and that they want to avoid compatibility issues
2015-02-28T15:03:31 < Tectu> so I think it's quite a "common" issue.
2015-02-28T15:03:34 < trepidaciousMBR> But the SD card would be shipped with the product, so it's less of a problem, as long as SOMEONE still makes SPI compatible cards we can get hold of
2015-02-28T15:03:54 < trepidaciousMBR> Bloody standards that aren't really standards :(
2015-02-28T15:04:28 < Tectu> trepidaciousMBR, that shouldn't be a problem. I you want me to give some more pointers (but no 100% guarantee) I never got a SanDisk one working. Lexar and TDK cards worked 100% of the times and Kingston worked 75% of the times (SPI mode)
2015-02-28T15:04:44 < Tectu> and when I say 75% of the times I mean that 3 out of 4 kingston cards worked
2015-02-28T15:04:47 < Tectu> not that it was unstable.
2015-02-28T15:05:25 < trepidaciousMBR> Tectu: Wow that sucks :(

2015-02-28T15:05:50 < Tectu> trepidaciousMBR, yes
2015-02-28T15:06:03 < Tectu> trepidaciousMBR, anyway. As I mentioned before I go microSD card with SDIO 100% of the time since then.
2015-02-28T15:06:39 < trepidaciousMBR> Yeah that would be much better...
2015-02-28T15:07:46 < Tectu> trepidaciousMBR, let me know when you ran some tests. I'm curious about the results
2015-02-28T15:08:00 < trepidaciousMBR> Tectu: Will do
2015-02-28T15:08:03 < trepidaciousMBR> Tectu: So minimal pins for SDIO would be D0, CK and CMD?
2015-02-28T15:08:19 < trepidaciousMBR> No, there must be more...
2015-02-28T15:08:59 < trepidaciousMBR> Apparently SPI is mandatory for SDIO cards, not that that matters: https://www.sdcard.org/downloads/pls/simplified_specs/archive/partE1_100.pdf
2015-02-28T15:09:22 < Tectu> trepidaciousMBR, I'm not sure. I always just used 4-bit mode
2015-02-28T15:09:30 < Tectu> trepidaciousMBR, I think you need CLK, D0 and CMD.
2015-02-28T15:09:37 < trepidaciousMBR> Yup that makes sense
2015-02-28T15:09:38 < Tectu> trepidaciousMBR, I know that it should be mandatory :P
2015-02-28T15:09:49 < dongs> then youre doing it wrong
2015-02-28T15:09:55 < Tectu> trepidaciousMBR, note that CMD is as far as I remember also D3 in 4-bit mode so you basically "save" a pin there
2015-02-28T15:11:47 < trepidaciousMBR> hm odd, different pins on F437
2015-02-28T15:15:34 < trepidaciousMBR> This really is pathetic - SDIO_D0 is only on PC8. This conflicts with DCMI_D2... ok so we will use DCMI_D2 somewhere else - it will have to be PE0. PE0 is FMC_NBL0, which occurs nowhere else. Slow *cking hand-clap for ST!
2015-02-28T15:18:16 < trepidaciousMBR> Or you can use DMCI_D2 on PH11, and take out FMC_D19
2015-02-28T15:21:49 < Laurenceb> SPI is mandatory for µSD
2015-02-28T15:23:05 < dongs> ^
2015-02-28T15:23:16 < dongs> if SPI was optional for microSD, zano would have been fucked
2015-02-28T15:23:22 < dongs> since PIC32 doesnt have SDIO
2015-02-28T15:23:27 < Laurenceb> ive never come across a card that didnt work.. eventually
2015-02-28T15:23:44 < Laurenceb> they are very sensitive to startup/power up procedure
2015-02-28T15:23:51 < Laurenceb> you need to get it exactly right
2015-02-28T15:23:58 < dongs> Laurenceb: lol some dickhead @ zano forums posted "pic32 has QSPI" (4 bit spi shit, for flash memory? or something) , so you can just use that as 4 bit SDIO
2015-02-28T15:24:01 < dongs> lol
2015-02-28T15:24:04 < Laurenceb> pullups on the spare lines and shit
2015-02-28T15:24:42 < trepidaciousMBR> Ah ha - we're only using 16 bits of data to SDRAM, so we can use PH11 for DCMI and PC8 for SDIO_D0
2015-02-28T15:25:01 < trepidaciousMBR> Laurenceb: Ah cool, so if we have to get SPI working we probably can, given enough messing about?
2015-02-28T15:25:11 < Laurenceb> yes
2015-02-28T15:26:08 < jpa-> i haven't tried many cards with SPI, because each and every card i have ever tried just worked
2015-02-28T15:26:57  * Laurenceb has a few thousand devices in service using spi and µSD
2015-02-28T15:27:17 < Laurenceb> encountered a few issues when cards were swapped and stuff :D
2015-02-28T15:27:50 < jpa-> but the thing to be aware is that SD card write speed is very nondeterministic
2015-02-28T15:28:01 < jpa-> they can easily make 0.5 - 1 second pauses in the middle of writing
2015-02-28T15:28:06 < Laurenceb> hmm
2015-02-28T15:28:10 < Laurenceb> ive never seen that
2015-02-28T15:28:16 < Laurenceb> 25ms worst case
2015-02-28T15:28:24 < jpa-> usually it is more like 10-100 milliseconds yeah
2015-02-28T15:28:42 < jpa-> but there are no guarantees and some people have seen very long delays also
2015-02-28T15:28:52 < Laurenceb> but i do preallocation and cluster link tables and shit
2015-02-28T15:28:52 < jpa-> so i usually calculate enough buffer space for 1 second
2015-02-28T15:28:55 < Laurenceb> to speed it up
2015-02-28T15:29:13 < dongs> jpa its 250 for SPI and 500 for SDIO
2015-02-28T15:29:28 < Laurenceb> in the spec...
2015-02-28T15:29:39 < Laurenceb> in reality decent cards are way faster
2015-02-28T15:29:47 < jpa-> and in reality crappy cards are worse
2015-02-28T15:29:51 < Laurenceb> lolz
2015-02-28T15:29:54 < dongs> There are two types of busies in a multiple block write operation.
2015-02-28T15:29:54 < dongs> (1) Write busy at block gap (without CMD12) is maximum 250ms
2015-02-28T15:29:55 < dongs> (2) Write busy after CMD12 is maximum 250ms (500ms for SDXC)
2015-02-28T15:29:55 < dongs> If CMD12 is issued during a multiple block write operation's busy period, the host timeout counter is
2015-02-28T15:29:57 < dongs> reset and the 250ms (500ms for SDXC) timeout period is measured from the response of CMD12.
2015-02-28T15:30:11 < Laurenceb> i only use Lexar/Samscum/Sandisk
2015-02-28T15:30:18 < Laurenceb> on work stuff
2015-02-28T15:30:44 < Laurenceb> which reminds me, I need a new server :-S
2015-02-28T15:30:48 < jpa-> it's nice if you can choose the cards, but if it is the kind of device where people might plug their own cards, then better prepare for the worst
2015-02-28T15:30:57 < Laurenceb> we will probably bug some mental IBM thing
2015-02-28T15:31:16 < Laurenceb> as the dataloggers are collecting ~100GB/day now
2015-02-28T15:31:36 < trepidaciousMBR> jpa-, Laurenceb: Thanks I'll keep that in mind - I should have pretty huge buffers in SDRAM for everything anyway.
2015-02-28T15:31:55 < trepidaciousMBR> I'll be picking my own cards too
2015-02-28T15:32:17 < trepidaciousMBR> Basically using SD as permanently fitted large storage, since it seems so much simpler than any other option
2015-02-28T15:32:40 < Laurenceb> yeah, same here
2015-02-28T15:33:07 < jpa-> uffs on spi nor flash is quite nice also
2015-02-28T15:33:34 < jpa-> or was it nand flash.. who knows
2015-02-28T15:52:01 < Tectu> dongs, what's your opinion on microsoft access?
2015-02-28T15:52:53 < dongs> its amazing

2015-02-28T15:55:58 < trepidaciousMBR> I think after trawling through the datasheet for a while, there is actually a set of pin assignments that gets you SDRAM, DCMI and SDIO at the same time, maybe even 4-bit SDIO. The only restriction is that SDRAM has to be 16 bit, which is fine :)
2015-02-28T15:56:18 < dongs> why ditnt yuou just use cube32mx
2015-02-28T15:56:25 < dongs> it would take you like 5 clicks to figure that out
2015-02-28T15:56:28 < Tectu> <Steffanx> you shuold ask what dongs's opinion is about ms access
2015-02-28T15:56:34 < Tectu> dongs, I think you should give your real opinion then ^
2015-02-28T15:58:57 < trepidaciousMBR> dongs: Is that some kind of awesome thing for assigning pins for you?
2015-02-28T15:59:08 < dongs> trepidaciousMBR: ya
2015-02-28T15:59:10 < trepidaciousMBR> I tried the olf eclipse plugin thing and hated it
2015-02-28T15:59:16 < trepidaciousMBR> old
2015-02-28T15:59:19 < dongs> cubemx is standalone
2015-02-28T15:59:36 < dongs> you can pick peripherals from dropbox or you can manually click on pins and select stuff and it'll warn you of conflict etc
2015-02-28T16:00:00 < dongs> but for shit like fsmc where you got tons of pins to assign, its very quick to get an idea of waht peripherals will be usable/not etc
2015-02-28T16:00:01 < Laurenceb> another day fighting the L3GD20...
2015-02-28T16:00:26 < trepidaciousMBR> Cool, I'll have a look at that.

2015-02-28T16:03:16 < Laurenceb> what the fuuuuuu
2015-02-28T16:03:23 < Laurenceb> why u 2 starts
2015-02-28T16:06:49 < trepidaciousMBR> repeated start with no bytes sent? ;)
2015-02-28T16:06:56 < Laurenceb> yeah
2015-02-28T16:07:21 < Laurenceb> then the next slave doesnt ack
2015-02-28T16:07:32 < Laurenceb> im guessing due to the rep starts
2015-02-28T16:07:49 < Laurenceb> as same device acked on the previous transaction
2015-02-28T16:10:26 < trepidaciousMBR> It does seem like a repeated start with no bytes should be allowed, but it would also be kind of pointless?
2015-02-28T16:12:34 < Laurenceb> well it screws up the bus
2015-02-28T16:12:38 < Laurenceb> thats for sure
2015-02-28T16:13:09 < trepidaciousMBR> :(
2015-02-28T16:14:54 < Laurenceb> looks like my modified EV7_2 hander screws up
2015-02-28T16:15:07 < Laurenceb> datasheet says it has to send stop
2015-02-28T16:15:14 < Laurenceb> im trying to make it send rep start
2015-02-28T16:15:21 < Laurenceb> but ive got an idea...
2015-02-28T16:16:08 < Laurenceb> going to modify the order of Rx read/start request between rep start and stop requests

2015-02-28T18:41:39 < trepidaciousMBR> They seem really keen on it, there's a long list of improvements they're making
2015-02-28T18:42:23 < ka6sox> BrainDamage, well they announced it…maybe its in the development tree
2015-02-28T18:42:40 < trepidaciousMBR> Apparently they support it because: The hardware fraternity at CERN believes that KiCad can do to PCB design what the GCC compiler did to software, letting design and development knowledge flow more freely in the open hardware community.
2015-02-28T18:42:52 < trepidaciousMBR> Not a bad argument :)

2015-02-28T19:06:46 < dongs> will be working tomrow also
2015-02-28T19:06:50 < dongs> that list could be handy
2015-02-28T19:07:01 < zyp> right
2015-02-28T19:07:12 < Getty> where did china go? holiday in brazil? #couldntresist
2015-02-28T19:08:12 < dongs> welp no zano news
2015-02-28T19:08:19 < dongs> they deleted my comment off their last video
2015-02-28T19:08:19 < dongs> lulz
2015-02-28T19:08:31 < emeb> kill all the trolls
2015-02-28T19:08:39 < zyp> hmm, I think it were only availability of phy, supercap and the connectors
2015-02-28T19:08:39 < dongs> the only comments they leave on their shit are retards drooling
2015-02-28T19:08:54 < dongs> It.s awesome when a developer takes a product with complex functions, programs away the clumsiness and delivers a simple user solution. The result is something for humans, not just geeks, genius. or those with 1000 hours to waste. I.m waiting for my Zano too, not just so I can see it zip around the sky, but because I want to be a part of this innovation.
2015-02-28T19:09:04 < Getty> hey, as i am new here, is there any more info we have here about zano, or is it just a general fun topic to laugh about the never ending kickstarter?
2015-02-28T19:09:30 < emeb> point n laugh
2015-02-28T19:09:54 < zyp> Getty, they're promising things they can't deliver, and we're watching it unfold
2015-02-28T19:10:10 < emeb> zyp: supercap for battery backup / RTC?
2015-02-28T19:10:19 < BrainDamage> pick your favourite dickstarter and watch things go like espected
2015-02-28T19:10:34 < zyp> emeb, yes
2015-02-28T19:10:39 < BrainDamage> it's like predicting the future, except there's a crapload of money and butthurt "investors" involved
2015-02-28T19:10:53 < zyp> emeb, weren't you here when I talked about it?
2015-02-28T19:10:58 < zyp> around a week ago
2015-02-28T19:11:02 < Laurenceb> even if they make <something>, GoPro will annihilate them
2015-02-28T19:11:13 < emeb> zyp: I might have been, but my memory... :P
2015-02-28T19:11:14 < Laurenceb> GoPro can actually make a camera
2015-02-28T19:11:19 < dongs> http://www.the-mrkt.de/wp-content/uploads/2015/02/zano-with-app.jpg
2015-02-28T19:11:33 < Laurenceb> loldongs
2015-02-28T19:11:45 < emeb> zyp: I  put a battery connector and 32K xtal on my latest board for giggles
2015-02-28T19:11:54 < emeb> need to test that out soon.
2015-02-28T19:12:11 < zyp> emeb, IIRC, F4 can do ~4 days on a 100mF supercap
2015-02-28T19:12:22 < zyp> if I ran the numbers right
2015-02-28T19:13:00 < emeb> not bad.
2015-02-28T19:13:05 < emeb> what's your app require?
2015-02-28T19:13:32 < zyp> no idea, it's not my app
2015-02-28T19:13:41 < Laurenceb> http://hackaday.io/project/2915-trsi-pocketqub-satellite
2015-02-28T19:14:08 < emeb> nice antenna
2015-02-28T19:14:18 < dongs> that is cool
2015-02-28T19:15:04 < zyp> it's mostly a convenience thing, for providing sensible timestamps between boot and first SNTP sync, but I think the worst consequence of not having real time there would be inaccurate timestamps in logs
2015-02-28T19:15:38 < zyp> proper logging when booted offline perhaps
2015-02-28T19:15:50 < emeb> ya
2015-02-28T19:16:05 < zyp> but it's a networked control system, it can't do much offline anyway
2015-02-28T19:16:42 < emeb> usually powered up
2015-02-28T19:16:57 < emeb> possibly powered off only for utility failures?
2015-02-28T19:17:11 < zyp> well, it's mobile
2015-02-28T19:17:18 < emeb> oh
2015-02-28T19:18:32 < Getty> somehow i feel reminded of the helicopter project i wanted todo with my dad, metal detector on helicopter
2015-02-28T19:18:36 < emeb> dat hellschreiber mode
2015-02-28T19:18:48 < emeb> not what I'd call "bandwidth efficient"
2015-02-28T19:19:35 < Getty> after first experiments where we still were pretty positive in mood, we had realized that "flying" is not a very... simple topic (not saying the helicopter is the problem, more like the influence on the physics around the helicopter, which are very relevant for the metal detector)
2015-02-28T19:19:59 < dongs> emeb: haha
2015-02-28T19:20:08 < Getty> if we would have made a kickstater before that we would have ended up like zano probably hrhr
2015-02-28T19:20:30 < zyp> emeb, mobile in the sense of temporary equipment at construction sites
2015-02-28T19:20:33 < dongs> k zzz
2015-02-28T19:20:35 < Getty> its doable, we just need much more development time
2015-02-28T19:20:49 < emeb> zyp: makes sense
2015-02-28T19:29:20 < Steffanx> dongs, you have such nice differential pairs. Why you dont do the length matching like http://wiki.altium.com/download/attachments/3080439/image033.jpg?version=1&modificationDate=1222402575854 ?
2015-02-28T19:29:49 < dongs> that is exactly what i did
2015-02-28T19:30:09 < dongs> except the 'pair' matching looked gay.
2015-02-28T19:30:15 < Steffanx> no, you "wiggle" them independently of each other
2015-02-28T19:30:18 < dongs> yeah

2015-02-28T19:33:16 < Steffanx> doesn't your current layout kind of breaks the entire idea behind the differential paring.

2015-02-28T20:39:03 < Laurenceb> lulwut maxim
2015-02-28T21:03:48 < karlp> trepidaciousMBR: fwiw, I have a sd card connected on spi on an openwrt board, and the newer cards work, older cards don't...
2015-02-28T21:03:52 < karlp> (very small sample size)
2015-02-28T21:04:17 < trepidaciousMBR> karlp: Hm, odd :)
2015-02-28T21:05:10 < jpa-> the problem with spi + sd cards is probably mostly that the specs are not freely available and most cards work without e.g. pull-up resistors and initial clock cycles etc.
2015-02-28T21:05:11 < karlp> trepidaciousMBR: you can always just drop a usb-card reader part on your board...

2015-02-28T21:12:09 < karlp> trepidaciousMBR: I'd go with jpas/laurences claims that getting your actual spi interface right you should be able to talk to anything, rather than tectu's frothing at the mouth about spi not being supported
2015-02-28T21:12:33 < karlp> (the reason my old card probably doesn't work is that my spi interface isn't correct either, we used 10k pullups instead of 50-100)
2015-02-28T21:12:35 < jpa-> though if sdio is possible, i'd probably use it also
2015-02-28T21:13:05 < jpa-> not because of risk, but because it is just neat ;)
2015-02-28T21:13:14 < karlp> yeah, we're looking at usb reader because usb is better supported tahn raw spi from the linux board side.
2015-02-28T21:13:42 < karlp> we already know we can get good speed with usb flash sticks, but the spi usd card is shitty perf wirse, 800kB/sec or something tops
2015-02-28T21:13:42 < trepidaciousMBR> On STM32 SPI and SDIO should both be fine though
2015-02-28T21:13:54 < karlp> yeah, this wasn't stm32
2015-02-28T21:14:04 < karlp> was just throwing in anecdotes on spi usd cards :)
2015-02-28T21:14:30 < jpa-> actually the one SD card trouble i have had is with a cheap chinese usb adapter.. it just totally didn't work with any card, so clearly usb is not supported!

2015-02-28T21:44:28 < green1> http://i.imgur.com/ormgXAj.png
2015-02-28T21:45:06 < green1> code size comparision with and without standard peripheral library.
2015-02-28T21:45:22 < jpa-> no gc-sections etc?
2015-02-28T21:46:08 < green1> i'm reading this book, it says code size get 2.5 times bigger than without SPL.
2015-02-28T21:46:20 < jpa-> no
2015-02-28T21:46:27 < green1> hi jpa
2015-02-28T21:46:31 < jpa-> it says stdperiph rcc + gpio takes 2 kB of space
2015-02-28T21:46:43 < jpa-> if your code is 50kB, it doesn't suddenly become 100kB
2015-02-28T21:46:59 < jpa-> i find that the size is the smallest of all the reasons to avoid stdperiph
2015-02-28T21:47:22 < green1> i see,
2015-02-28T21:47:51 < green1> do you use or avoid SPL ?
2015-02-28T21:48:25 < jpa-> i occassionally run into it in work projects, but i would never put it into a new project myself
2015-02-28T21:48:53 < jpa-> not so sure about stm32cube, haven't used it
2015-02-28T21:49:05 < green1> i see,
2015-02-28T21:51:27 < green1> i use, keypad matrix , to scan keypad, i should activate one output and make all others inputs to avoid shorting.
2015-02-28T21:51:57 < jpa-> i would probably configure all pins as open-drain output and enable internal pull-up
2015-02-28T21:52:47 < green1> i see,
2015-02-28T21:53:02 < jpa-> then you can turn one column on at a time, read result on row inputs, and if you get a zero on any other column output, you know there is ghosting going on
2015-02-28T21:58:34 < green1> is it ok to let outputs to get short , in case same raw button press together. ?
2015-02-28T21:58:51 < jpa-> no, not for normal outputs
2015-02-28T21:58:58 < jpa-> for open-drain with pull-ups it is ok
2015-02-28T21:59:21 < green1> i got your point, i see thank you.

2015-02-28T22:23:38 < jpa-> but maybe if the new layer actually adds something useful
2015-02-28T22:23:50 < jpa-> unlike the stdperiph abstraction, which only worsens things
2015-02-28T22:23:50 < green1> so do you make your own libraries ? ,
2015-02-28T22:24:25 < jpa-> green1: i either use registers directly (they are quite easy to use) or use chibios

2015-02-28T22:25:27 < jpa-> if you look at stdperiph functions, 99% of those are just like    if (xyz_state == ENABLED) FOO->BAR |= FOO_BAR_XYZ; else FOO->BAR &= ~FOO_BAR_XYZ;

2015-02-28T22:51:35 < Laurenceb_> whats the output format?
2015-02-28T22:52:15 < jpa-> text
2015-02-28T22:52:37 < Laurenceb_> time, address, data     sort of thing?
2015-02-28T22:54:26 < jpa-> it's somewhat annoying in that it doesn't put time there.. with loglevel 3 you get the sample number though
2015-02-28T22:55:10 < jpa-> but otherwise it is something like "WRADDR: 0x78" "ACK" "WR: 0x8f" "ACK" "REPSTART" "RD: 0x76" "ACK"  each on own line
