[00:23:20] <_ami_> Lambda_Aurigae: thanks.
[01:55:22] <rue_bed> usart, with ttl to usb cnverter
[05:44:47] <liwakura> is there an god channel for Electrical Engineering questions?
[05:44:53] <liwakura> I want to backpower an ATX supply
[05:51:40] <daey> liwakura: backpower?
[05:51:54] <liwakura> like, i was to switch between two different power supplies
[05:52:11] <liwakura> and i want to investigate if i would really need relais for that
[05:52:35] <liwakura> and no, since we are talking of like 20 amps, i have not considered transistors
[06:00:44] <twnqx> why not?
[06:00:50] <twnqx> 20A is not much for a mosfet
[06:01:35] <_ami_> liwakura: try #electronics?
[06:02:03] <_ami_> twnqx already replied to your query though. :)
[06:02:19] <liwakura> nah
[06:02:34] <liwakura> im actually just too lazy to switch it off from the circuit
[06:02:51] <twnqx> so get two big diodes and OR the supplies?
[06:02:55] <liwakura> also, the buffer caps inside the ATX would of use in the outside circuit
[06:03:20] <twnqx> generally, i'd expect the PSU to die
[06:03:51] <twnqx> but it depends how the output stage is built. if they use diode rectification it should work
[06:04:08] <liwakura> its an switching power supply with friggin big caps
[06:04:11] <twnqx> if they use active rectification with mosfets, the reverse body diodes would be your problem
[06:06:04] <Lambda_Aurigae> http://www.add2psu.com/
[06:10:02] <Lambda_Aurigae> http://www.burningissues.net/how_to/power/psu.htm
[06:11:00] <Lambda_Aurigae> http://www.eetimes.com/document.asp?doc_id=1273185
[06:11:08] <Lambda_Aurigae> those should give you some ideas.
[07:26:26] <eszett> hi!
[07:26:34] <eszett> anyone got some bus pirate?
[07:27:21] <eszett> I'd like to do a self test of bus pirate v3.5c, with TeraTerm, but somehow the bootloader doesn't seem to answer..
[07:27:58] <LeoNerd> What's the question?
[07:29:08] <eszett> The problem is why do i get an error when sending "Hello" to the bootloader
[07:32:03] <eszett> For example, when im trying to update the firmware with the ds30Loader tool, its says "Searching for bl . . . . . . . . . . . . . . . . . . . . timed out"
[09:29:27] <piecat> Hey guys, I'm looking to make a keyboard that can type unicode characters. I can't really find anything online about this sort of thing, does anyone have any ideas on how I could implement it?
[09:29:46] <piecat> I was thinking of using AutoHotKey unicode, but it would be annoying to have to install that on every computer I want to use it on.
[09:30:15] <piecat> And then just have CtrlShiftAlt+number be reassigned to whichever characters I want to type
[09:30:31] <piecat> I was also thinking of using alt-codes, but most of the symbols I wanted to use don't have alt codes
[09:53:54] <eszett> I there a way to self-test a Atmega32u4?
[09:55:04] <eszett> to check if the crystal works, if the pins dont have solder bridges, etc. Can i check this with software, or do i have to go the combersome way of testing all this with a multimeter, oscilloscope, etc?
[10:03:32] <bss36504> There would be no way to have a BIST check the conditions on external pins in application, so no. Historically board-level JTAG has been used to verify that devices on a PCB are operating normally. You can chain multiple JTAG devices together and address them individually.
[10:03:59] <bss36504> You could however write some software to check *your* application
[11:12:56] <bss36504> Here's a neat paper that describes how to easily calculate phase angle for a given duty cycle in phase-cut power control systems: http://jase.esrgroups.org/papers/6_1_4_12.pdf
[12:36:54] <Emil> Hey
[12:37:26] <Emil> Anyone have a eaglefile for the atmega328pb?
[12:49:13] <LeoNerd> Not an eagle, no. I have a KiCad :)
[12:49:27] * LeoNerd also has a nice breakout board for it for sale, if you want one <.<
[12:51:37] <Tom_itx> should be the same pinout as the regular 328 no?
[12:51:50] <LeoNerd> It adds some extra pins
[12:52:03] <Tom_itx> i'd make you one for $20 :D
[12:52:26] <LeoNerd> There's a 4-bit PORTE now; PE0 and PE1 are where there used to be power pins, PE2 and PE3 are digital-capable pins where there used to be ADC6/ADC7
[12:53:31] <Tom_itx> ahh
[12:53:39] <Tom_itx> i haven't been keeping up lately
[12:54:47] <LeoNerd> https://www.tindie.com/products/leonerd/atmega328pb-development-board is my thing anyway
[12:55:04] <LeoNerd> I need to get some better photos
[12:56:15] <bss36504> Thats some nice silkscreen, cheers!
[12:57:12] <LeoNerd> The icons?
[12:57:38] <bss36504> Yeah, I like the I2C/SPI/UART symbols, they are a nice touch.
[12:57:55] <bss36504> Oh and the logo on the bottom is a nice touch
[12:58:16] <LeoNerd> I put that logo on everything :)
[12:58:36] <LeoNerd> Butyah; the I²C/SPI/UART helper icons I found useful, because those are the IO lines you're most often wanting to find
[12:58:59] <bss36504> I need to make myself a logo. Also should get in the habit of versioning my prototypes in silk haha
[12:59:23] <LeoNerd> The trick with logos in silkscreen is that most fabs will blow out the edges a bit
[12:59:32] <bss36504> I'm super lazy when it comes to silk, I tend to just shut those layers off since they clutter everything up, then I forget to fix them after.
[12:59:42] <LeoNerd> So you have to inset the edges of the logo in the technical file, so when they blow it out it comes out OK
[12:59:43] <bss36504> Oh really? So you have to undersize your lines?
[12:59:54] <bss36504> Gotcha
[13:00:09] <Tom_itx> somewhat yes
[13:24:17] <Emil> LeoNerd: Where are the resistors for the leds?
[13:24:22] <Emil> Underneath?
[13:24:57] <Emil> Ah, there were other pis
[13:24:58] <Emil> pics
[13:25:03] <Emil> looks nice : )
[13:25:41] <LeoNerd> Doublesided :)
[13:26:08] <Emil> Do you handmake them?
[13:27:16] <LeoNerd> Yup
[13:27:31] <LeoNerd> oshpark+oshstencils, hot-air gun. hand PnP
[13:28:05] <Emil> Nice
[13:28:32] <Emil> Your site is not there : /
[13:28:38] <LeoNerd> Mm?
[13:28:47] <Emil> leonerd.org.uk
[13:28:53] <LeoNerd> Why would it be.
[13:28:57] <LeoNerd> *hint* try "www." ;)
[13:29:08] <Emil> Bah
[13:29:16] <Emil> "www." is a thing of the past
[13:29:28] <Emil> At least have a cname for it
[13:29:29] <LeoNerd> www. is a thing because HTTP clients don't use SRV :/
[13:31:04] <Xionaba> is there an atmel icsp that works for most atmel microcontrollers?
[13:37:51] <bss36504> Atmel ICE supports all atmel processors
[13:38:00] <bss36504> Programming and Debug
[13:38:46] <Tom_itx> their new one is cheap too
[13:39:27] <Xionaba> ahh nice! thank you very muuch
[13:39:34] <bss36504> Yes, the Atmel ICE is the replacement for the JTAG ICE3 which was I think $85. the new ICE is around $50 for the whole kit if memory serves
[13:40:26] <APic> Hello B-)
[13:40:29] <Emil> bss 133.7$
[13:40:31] <Emil> bss36504:
[13:40:49] <bss36504> @Emil what?
[13:41:00] <Emil> costs 133.7$
[13:41:03] <Emil> Not 50
[13:41:04] <bss36504> Nooooo
[13:41:15] <bss36504> Oh wait
[13:41:20] <Emil> http://www.atmel.com/tools/atatmel-ice.aspx#buy
[13:41:25] <bss36504> did the price go up? no friggen way I paid that much
[13:41:43] <bss36504> http://www.mouser.com/ProductDetail/Atmel/ATATMEL-ICE-ADPT/?qs=KLFHFgXTQiCkJExmjis%2F7w%3D%3D&gclid=Cj0KEQjw8pC9BRCqrq37zZil4a0BEiQAZO_zrCp0_KfUw0h0STFjVdBfyEON_uluPeK4zorRm2Hn7dIaAs6R8P8HAQ
[13:42:01] <Emil> Wot
[13:42:03] <Emil> :D
[13:42:07] <Emil> Dat price difference
[13:42:15] <Emil> is that the same thing?
[13:42:19] <bss36504> Yeah I think i even bought through atmel....not sure why the price is so high now.
[13:42:34] <bss36504> Yes, the mouser one is the whole kit that I have
[13:42:48] <Emil> Yeah, the ADPT package costs that much from atmels site
[13:42:48] <bss36504> I bought one right when they were new, maybe that has something to do with it.
[13:42:54] <Emil> But it doesn't include the main unit
[13:43:04] <Emil> ATATMEL-ICE-ADPT: 10-lead squid cable, flat cable (10-pin 50mil connector and 6-pin 100mil connector) and adapter board (20-pin 100mil connector, 6-pin 50mil connector and 10-pin 100mil connector)
[13:43:18] <Emil> So mouser might be selling it for cheaper than they are supposed to :D
[13:43:21] <Emil> Might as well grab one
[13:43:37] <bss36504> No I think the ADPT includes the programmer
[13:43:55] <Emil> Not according to Atmel
[13:44:03] <bss36504> IM SO CONFUSED NOW
[13:44:23] <Emil> -ICE, -ICE-BASIC and -ICE-PCBA include the main unit
[13:44:25] <bss36504> Well the mouser one I linked is the ADPT, it would be misleading if that kit didnt include the actual programmer
[13:44:34] <Emil> Indeed
[13:45:03] <Emil> http://www.mouser.com/catalog/specsheets/EM104-I613.pdf
[13:45:05] <Emil> .DDDDD
[13:45:13] <Emil> The datasheet on Mouser's site links to that
[13:45:15] <bss36504> Oh now look here http://www.mouser.com/Search/ProductDetail.aspx?qs=KLFHFgXTQiDAUrt43H15kQ%3d%3d
[13:45:16] <Emil> Alrighty then
[13:45:24] <bss36504> Lol
[13:45:29] <bss36504> good one mouser
[13:45:45] <bss36504> Ok, so I guess the price went up. No way I payed $130 for it. Sorry gang
[13:45:55] <bss36504> Either way, very nice programmer
[13:45:59] <Emil> Showstopper : (
[13:46:32] <bss36504> Alternatively you could probably pick up a JTAG ICE3 for cheap. I had one of those too. Actually I should find out which friend I loaned that to.
[13:50:00] <bss36504> Ok, Emil, I went and found the invoice, I was right, I paid $49USD for the -BASIC kit. Maybe the microchip merger drove prices up...
[13:50:35] <bss36504> Purchased on 1/19/2015
[13:51:46] <Emil> Damn
[13:51:52] <Emil> That's pretty nice
[13:52:01] <bss36504> Yeah.
[13:52:08] <Emil> Hey LeoNerd
[13:52:12] <Emil> I'll take the Kicad file
[13:52:19] <Emil> Eagle fucking infuriates me
[13:52:27] <bss36504> Now, what you could do is buy the PCBA kit, and just have a bare board programmer
[13:53:18] <bss36504> And actually the PCBA kit plus the cable kit puts it at around $75. Not great but not terrible. If you have a 3D printer an enclosure would be trivial
[13:53:31] <Emil> I cold laser cut one easily
[13:53:42] <bss36504> Oh even cooler
[13:53:57] <bss36504> If it was me I'd consider that deal.
[13:54:17] <bss36504> But for now I'll just appreciate my luck and take good care of my ICE
[13:54:40] <Xionaba> within the country we only have atmel ICE basic kit, will that work for a all chips?
[13:55:12] <bss36504> Yeah the programmer covers all AVR and SAM processors. so everything they make
[13:55:29] <Xionaba> great! thanks again
[13:55:41] <bss36504> No problem
[13:58:34] <Emil> LeoNerd: pls rspd
[13:58:58] <bss36504> pls
[14:20:51] <LeoNerd> Emil: hi. (was cooking)
[14:21:25] <Emil> LeoNerd: it e
[14:21:37] <Emil> seems like kicad already has a part for atmega328pb
[14:21:42] <LeoNerd> Ahreally?
[14:21:44] <LeoNerd> That's new
[14:21:44] <Emil> So not at the moment needed
[14:21:48] <LeoNerd> OK
[14:21:56] <Emil> Well, I downloaded a nightly build :D
[14:22:04] <Emil> (But still, please share : ) )
[14:22:27] <LeoNerd> http://home.leonerd.org.uk/local/atmega328pb-a.lib
[14:27:11] <Emil> Thanks
[16:10:47] <Emil> LeoNerd: http://emil.fi/jako/ref_v1.sch
[16:10:53] <Emil> Any pointers?
[16:11:08] <LeoNerd> about...?
[16:17:55] <Emil> Cannot get it to pcbnew
[16:18:06] <Emil> but apparently I need to define footprints first
[16:18:12] <LeoNerd> Ah; more of a kicad question.. yes; I see you're over in #kicad too
[16:49:33] <_ami_> To use avr with LTC1799 oscillator, the fuse settings at http://www.engbedded.com/fusecalc/ would be "Ext. clock"?
[16:50:04] <LeoNerd> "ext clock" means "feed me a square wave on CKIN"
[16:50:10] <LeoNerd> So if the oscillator generates that, sure
[16:51:17] <LeoNerd> Seems an interesting chip - why that rather than a crystal?
[16:52:00] <_ami_> LeoNerd: i just solder them. looks wonderful! need to try it. https://pbs.twimg.com/media/CpH8_MMUEAIsnQy.jpg:large
[16:52:13] <_ami_> LeoNerd: http://cds.linear.com/docs/en/datasheet/1799fd.pdf
[16:52:20] <LeoNerd> Yes, I'm aware of what it is
[16:52:23] <LeoNerd> My question is why you're using it
[16:53:50] <_ami_> well, i need to check how AVR behaves on high speed. basically on overclocking. and i have these chips for long time. wanted to have them on dip board to actually use their worth. ;0
[16:57:25] <LeoNerd> Ah, just experimenting? I'd just use my siggen
[16:58:14] <Lambda_Aurigae> at 16mhz, 200Khz drift? this is precision?
[16:58:42] <LeoNerd> The frequency is set with a resistor. You're not going to get xtal-levels of precision :)
[16:58:59] <Lambda_Aurigae> but the web site says it is a "precision oscillator"
[16:59:11] <LeoNerd> Hah
[16:59:20] <LeoNerd> The word "precision" is far over-used in data sheets, I find
[16:59:27] <Lambda_Aurigae> yes.
[16:59:42] <Lambda_Aurigae> marketing speak
[17:00:06] <_ami_> Lambda_Aurigae: https://youtu.be/PNpb3vWbGRc?t=291
[17:00:29] <Lambda_Aurigae> that might be bad enough to cause issues with USART comms at 9600 bits per second when running at 16MHz.
[17:00:30] <_ami_> yeah, u r right. :P
[17:00:45] <_ami_> it drifts a lot on high speed.
[17:03:09] <Lambda_Aurigae> pretty much it looks like a high speed 555 timer.
[17:03:42] <LeoNerd> Yeah, basically
[17:04:13] <_ami_> i shall experiment on it and post the results soon.
[17:04:55] <Lambda_Aurigae> I need to rebuild my low speed avr platform.
[17:05:14] <Lambda_Aurigae> used a multiturn pot and a 555 timer to generate clock for an avr years ago..
[17:05:26] <Lambda_Aurigae> so I could slow it waaay down to see what was happening.
[17:07:11] <Lambda_Aurigae> nifty being able to watch i/o lines toggle as the clock pulses hit and count clock pulses between events and such with the naked eye.
[17:23:28] <_ami_> ok
[17:24:41] <_ami_> how is the Saleae Logic analyser. i bought a cheap one from aliexpress. got delivered it today. looks decent though. atleast shows what ltc1799 is givingg
[17:24:58] <LeoNerd> I have a £20 clone of one
[17:25:09] <LeoNerd> It seems good enough. I don't push it past about 4MS/sec though
[17:25:17] <LeoNerd> It -claims- it can do 24. I don't think it can
[17:25:54] <_ami_> yeah, it claims to do up to 24 Mhz.
[17:26:43] <_ami_> LeoNerd: mine is cheaper one. i think its around 6$
[17:28:56] <_ami_> i like the software gui though. espcially the color theme. i like dark since i use enlightenment (https://www.enlightenment.org/) as window manager. matches with its theme nicely :)
[17:31:22] <_ami_> LeoNerd: i did the smd soldering for first time and it was so easy. its lot easier than dip one. i have soldered TSOT-23 pkg ICs.
[17:31:23] <_ami_> although i did watch few videos on youtube before trying.
[17:31:29] <LeoNerd> Mmm... :)
[17:31:52] <LeoNerd> Yeah.. I now find stencil/paste/hotair easier than TTH most of the time
[17:31:55] <Lambda_Aurigae> videos on youtube
[17:32:23] <Lambda_Aurigae> I learned soldering by taking things apart with a soldering iron....then trying to put them back together when my dad got pissed that I had just disassembled his hifi set.
[17:32:36] <_ami_> Lambda_Aurigae: haha!
[17:32:57] <Lambda_Aurigae> I learned soldering before youtube was....before the internet was...
[17:33:05] <_ami_> LeoNerd: that would be the next step for me. first i try to good at it. :)
[17:33:10] <Lambda_Aurigae> 40ish years ago.
[17:33:38] <Lambda_Aurigae> but I did get that hifi set back together and it worked!
[17:33:57] <Lambda_Aurigae> resoldering those fine cloth covered wires on the antenna coil were a bitch though.
[17:34:45] <Lambda_Aurigae> I was 9 and using a soldering gun.
[17:37:52] <_ami_> wow!
[17:37:53] <_ami_> i think you must have learned a lot from your dad.
[17:37:53] <_ami_> i shall try to give the same nurture environment to my toddler. he is going to turn 2 years on 8th August :D just 2 days.
[17:37:54] <_ami_> he is a curious mind.. whenever i am in my small lab, he comes and say "Dad, what are you making? " :)
[17:38:22] <_ami_> Lambda_Aurigae: oh boy! you are an inspiration :)
[17:38:46] <Lambda_Aurigae> I did learn a lot from my father.
[17:39:14] <Lambda_Aurigae> I learned more from being told "Put that damned thing back together before I beat you to within an inch of your life!"
[17:39:23] <_ami_> haha :)
[17:40:28] <Lambda_Aurigae> at 12 I was repairing old tube TVs for the old people who didn't want to upgrade to the new fangled solid state ones.
[17:40:51] <Lambda_Aurigae> mostly it was, look for a tube that doesn't glow and find something that looks close and try it.
[17:41:35] <Lambda_Aurigae> I would ride around town on my bike on trash day with a screwdriver and pull the tubes out of TVs sitting beside the road waiting for the trash truck.
[17:42:33] <carabia> you old commie you
[17:43:15] <Lambda_Aurigae> nope...I'm an anarchist.
[17:43:25] <carabia> Whatever.
[17:43:40] <carabia> within an inch of your life... -- Our integrity sells for so little, but it is all we really have. It is the very last inch of us, but within that inch, we are free.
[17:43:57] <Lambda_Aurigae> hehe.
[17:44:02] <carabia> inches are serious business.
[17:44:12] <Lambda_Aurigae> my father was also fond of, "I brought you into this world, I can take you out of it."
[17:45:09] <carabia> sounds a bit like my old man but he was too scrawny to actually do anything about it
[17:45:15] <Lambda_Aurigae> when I was about 15 I said, "No you didn't. You were at work when I was born and mom was unconscious from the drugs. The doctor brought me into this world."
[17:45:42] <Lambda_Aurigae> I found myself laying on the floor after being backhanded so hard it knocked me out of the chair at the dinner table.
[17:46:23] <carabia> Yeah, nothing really tells you to shut the fuck up better than the ol' backhand.
[17:46:27] <Lambda_Aurigae> that's the only time I ever remember actually backtalking my father.
[17:46:49] <Lambda_Aurigae> do that these days and you spend the rest of your life in jail for child abuse.
[17:47:06] <Lambda_Aurigae> but to this day I won't backtalk my father....I just don't talk to him at all.
[17:47:32] <carabia> I remember the only time I backtalked my old man was about a week before he went to the terminal clinic.
[17:47:36] <_ami_> my dad is a geography professor so i did not actually learn anything "real" science. :P
[17:47:41] <_ami_> from him.
[17:48:28] <carabia> Afterwards he got a bit fuzzy, the doctors figured the lung cancer had spread to his brain
[17:48:44] <Lambda_Aurigae> I learned science from reading the science encyclopedia...20ish volumes or so...before I was in 3rd grade.
[17:48:58] <Lambda_Aurigae> ok..gotta go help the wifey pick veggies in the garden.
[17:49:15] <carabia> maybe you're a hippie instead of an anarchist
[17:50:13] <carabia> Hippies are too damn lazy to do anything about it which separates them from anarchists. Or well, I think anarchists are loud-mouthed but also too damn lazy to do anything about any of the things they bitch about.
[17:50:59] <carabia> ...At least the hippies can farm. At least the non-urban-flavored
[17:51:39] <carabia> Also hello _ami_, what's cookin?
[17:51:52] <carabia> Tikka masala?
[17:52:09] <_ami_> carabia: haha, its 4 am here. :P
[17:52:27] <carabia> Yeah, figured as much
[17:52:52] <carabia> Half an hour 'til the olympic opening ceremony, gonna have to stay up.
[17:53:34] <carabia> Though, I doubt any future event will ever outdo Beijing 2008.
[17:53:43] <_ami_> btw, i was trying out the new stuffs got from aliexpress today. experimenting with ltc1799 and the brand new cheap Saleau logic analyzer. :P
[17:54:06] <carabia> What's an ltc1799?

[17:54:40] <_ami_> its an oscillator
[17:54:57] <_ami_> can generate feq from 1 Khz to 33 Mhz
[17:55:05] <_ami_> http://cds.linear.com/docs/en/datasheet/1799fd.pdf
[17:55:48] <carabia> it's 1:30 here, ain't nobody got time for datasheets. Square wave?
[17:56:03] <_ami_> carabia: Yup
[17:56:30] <_ami_> can be used as clock source to AVR
[17:56:31] <carabia> So what are you using this for? generating clocks for mcus?
[17:57:03] <carabia> how much $$ are these per piece in low qty?
[17:57:08] <_ami_> yes, that was the plan but i got carried away by testing logic analyzer
[17:57:16] <_ami_> carabia: its a clone i think. 6$
[17:57:25] <carabia> $6???
[17:57:46] <carabia> Why the fuck would you want to use this to replace an xtal?
[17:57:58] <_ami_> oh sorry.. i gave you the price of logic analyzer.
[17:58:13] <_ami_> i think its around 2$ per chip.
[17:58:48] <carabia> mehh still on the expensive side of things
[17:59:15] <_ami_> well, i just want to use it for my experiments with overclocking AVRs.
[17:59:28] <carabia> overclocking? why?
[18:00:03] <carabia> "overclocking avrs" is really an indication that you're doing something massively wrong... :)
[18:01:04] <_ami_> carabia: its for personal use only. :) if few opcode are missed by avr is not going to hurt me on high speed. :P
[18:01:14] <carabia> the only practical solution i can think of is to run megavrs with out-of-spec clocks at 3v3 but even then i'd probably get something that clocks faster in-spec.
[18:02:09] <carabia> cause iirc all of them are specced up to only 8 MHz at 3v3
[18:02:48] <_ami_> carabia: https://www.youtube.com/watch?time_continue=47&v=KVRvWmcxnA0 :P
[18:03:06] <_ami_> cooling down avr by liq. nitrogen :P
[18:04:08] <carabia> I guess I'm too practical to appreciate this fear.
[18:04:10] <carabia> feat*.
[18:05:07] <carabia> You're not really going to do anything with that anyway...
[18:05:26] <carabia> So, it's just for shits and giggles?
[18:05:31] <_ami_> :P
[18:08:39] <carabia> oh and that LA you got, is it the one specced to 24 MHz?
[18:09:00] <_ami_> yeah :(
[18:09:05] <carabia> yeah okay
[18:11:21] <_ami_> carabia: http://www.aliexpress.com/item/1sets-New-Arrival-USB-Logic-Analyze-24M-8CH-MCU-ARM-FPGA-DSP-debug-tool/2020974930.html?spm=2114.13010608.0.79.QMwgxP
[18:11:34] <carabia> yes i know i've got one
[18:11:47] <_ami_> okay.
[18:11:48] <carabia> but i've been interested in getting one of these for a while
[18:11:51] <carabia> http://www.seeedstudio.com/depot/Open-Workbench-Logic-Sniffer-p-612.html
[18:13:08] <carabia> aliexpress also sells a high sample rate saleae clone that _supposedly_ does 100 MHz on 3 channels
[18:13:21] <carabia> for like $20 or so, but maybe this is a safer bet.
[18:14:41] <carabia> I'm gonna need a new LA to be able to debug fast serial comms
[18:16:13] <_ami_> if i get the good feedback on 100 Mhz/3 channels, i would buy it.
[18:16:14] <carabia> And also the external trigger is nice to have, e.g. to use with a proper scope
[18:16:57] <carabia> I have no idea what kind of a software this thing needs though
[18:17:34] <carabia> the saleae software is quite nifty, but I don't think this is compatible
[18:18:56] <_ami_> the clone one?
[18:19:21] <_ami_> it works okay for me with Saleaue software
[18:19:25] <carabia> with the clone you can use their software
[18:20:19] <carabia> but i think it's some sort of a proprietary protocol and anyone selling logic analyzers legit don't want to go there
[18:21:10] <carabia> seeed being legit is a dubious proposal at best though I guess
[18:23:09] <LeoNerd> For any LA I'd just run sigrok
[18:23:46] <carabia> Anyway, olympics. Laters.
[18:26:40] <_ami_> time to sleep. 4.30 am here
[18:26:41] <_ami_> nn
[23:47:27] <Emil> Hey
[23:48:08] <Emil> Are avrdude, avr-gcc, binutils-avr and avr-libc (and the rest if I forgot) patched for atmega328pb already?
[23:48:20] <Emil> If not, I bet someone has a patch
[23:49:55] <Casper> what's the difference between the 328 and 328pb?
[23:50:07] <Casper> isn't it binary compatible?
[23:50:23] <_ami_> Emil: http://savannah.nongnu.org/forum/forum.php?forum_id=8461 the stable release does not have
[23:50:38] <Emil> It is but there is no valid signature by default and the extra registers have not been mapped
[23:50:45] <_ami_> supported mm38bp, m88bp, and 168bp
[23:51:17] <Emil> yeah
[23:51:22] <Emil> what _ami_ linked
[23:51:33] <Emil> so someone does have their own patch, right?
[23:52:16] <_ami_> Emil: i think LeoNerd was trying to setup avrdude & avr-libc for m328bp
[23:52:46] <_ami_> and Emil, you would beed to add support of m328bp into avr-libc too
[23:52:54] <_ami_> need*
[23:53:48] <_ami_> Emil: you can check avrdude development branch, may be someone had already added the support for this chip
[23:54:09] <_ami_> into dev branch.
[23:54:51] <Emil> How can I acquire it?
[23:56:00] <_ami_> Emil: http://savannah.nongnu.org/svn/?group=avrdude
[23:57:31] <_ami_> svn co svn://svn.sv.gnu.org/avrdude/trunk/avrdude
[23:59:20] <_ami_> i wonder why the avrdude devs uses svn till now. svn is like dinosaur age thing.
