[01:08:59] <anonnumberanon> LoRez, Mr_Sheesh damn I meant can I ouput a sine wave with them? I guess not if they are inputs.
[01:12:51] <Mr_Sheesh> They can be bidirectional but no analog output - you could use "Magic Sine Waves" (Search for those, iirc tinaja.com has some info on those) or PWM and low-pass filter to create a sine wave output
[01:14:34] <Mr_Sheesh> There also are DACs and the like, which are Digital to Analog Converters, you'd send the voltage level to output to the DAC and it handles the fine details etc.
[01:31:44] <anonnumberanon> Mr_Sheesh, thans.
[02:19:17] <jaggz> if I want to sound an alarm.. pretty much any noticable sound will do.. what are my options?
[02:19:42] <jaggz> (I'd like to know the options, and if I need an AVR with DAC's)
[02:22:43] <jaggz> for example, I want to make a thermometer for something in the kitchen which, if it goes above 90degF, will alert me in the next room
[02:26:00] <apo_> just do a 1kHz square wave?
[02:30:00] <STS_Patrik> relay and train horn
[02:30:02] <malinus> jaggz: 1) what do you need a dac for? 2) just use a sirene sound generator
[02:30:06] <apo_> anonnumberanon: you can do PWM and output a sine, but it's not necessary
[02:32:33] <malinus> jaggz: I'm asking about the DAC, because there are no 8-bit avrs with DAC.
[02:32:53] <malinus> wait nvm
[02:33:14] <jaggz> :)
[02:33:15] <malinus> there is a couple, my bad
[02:33:22] <jaggz> what are the complexities with using 32 bit avrs?
[02:33:44] <malinus> the complexity is - don't use it, use some 32-bit ARM instead :D
[02:34:00] <malinus> from STM probably
[02:34:43] <jaggz> what does 32 bit give me?
[02:34:49] <jaggz> or.. anyone
[02:34:59] <jaggz> higher memory access?
[02:35:16] <jaggz> (I mean.. is that the point?)
[02:35:43] <malinus> you can't really compare it. Speed, memory, IO, peripherals. List goes on.
[02:35:48] <jaggz> k
[02:36:16] <malinus> 32-bit timers @ 160MHz etc.
[02:37:40] <jaggz> okay.. probably don't need much of any of that for now
[02:37:56] <jaggz> 8 bit are just 256 levels of io though?
[02:39:46] <jaggz> hmm.. 10 bit
[02:40:07] <LeoNerd> PWM is usually fine for a simple alert tonr
[02:40:09] <LeoNerd> tone
[02:40:09] <ravon> jaggz: If you mean the UC3 series, they are abandoned by Atmel.
[02:40:23] <jaggz> LeoNerd: thanks.. :)
[02:40:30] <LeoNerd> If the squarewave sounds too harsh, a simple RC lowpass can smooth it out
[02:40:42] <jaggz> ravon, no.. no reference in general.. just learning. I'm very new to mcu's
[02:41:30] <jaggz> first projects will be a set of buttons (for mouse), and a way to simulate scrollwheel with button presses instead of rolling a wheel
[02:42:21] <jaggz> here's the current button set, with 3 buttons:
https://www.flickr.com/photos/32284628@N05/with/16303375531/
[02:42:31] <jaggz> the pink thing
[02:42:40] <jaggz> actually that's a new one.. haven't hooked it up to that mouse yet..
[02:43:00] <jaggz> but instead of running wires to the mouse I'm going to try my hand at using an MCU.. then I can do the scrollwheel
[02:43:03] <ravon> jaggz: Stay away from AVR32 and use some ARM chip instead. Atmel does not maintain their gcc branch so you are stuck at 4.4.7 which is from 2012.
[02:43:39] <jaggz> ravon, I'll probably just avoid it altogether for now.. the 8bits should work fine for my simple projects
[02:43:51] <ravon> jaggz: oki :)
[02:43:55] <jaggz> and will probably take your advice if I go beyond that
[02:44:18] <jaggz> I can use a current gcc for these 8 bits no?
[02:45:26] <jaggz> I'll find out when I'm at that point.. I've ordered a programmer and haven't even ordered my mcu's yet..
[02:45:49] <jaggz> figured I'd order a handful of attiny85's and some higher capability ones.. (attiny84's I think)
[02:55:33] <ravon> jaggz: Sally:TelitManager marco$ avr-gcc --version
[02:55:33] <ravon> avr-gcc (GCC) 4.8.3
[02:56:16] <jaggz> interesting command prompt :) thanks for the version info

[03:02:09] <ravon> malinus: From my view that's sci-fi :(
[03:02:59] <ravon> It doesn't even have nullptr in its C++11 implementation :)
[03:34:44] <hetii> HI :)
[03:50:04] <hetii> Is it possible to use fiber optical Lan card (or normal lan card wit some stuff) and instead fiber use pointer laser (or disco laser 100mw)?
[03:50:45] <Tom_itx> no, you need a 40w laser for that
[03:51:08] <hetii> ?
[03:51:28] <hetii> co cut everything in around :>?
[04:02:16] <hetii> http://www.ted.com/talks/harald_haas_wireless_data_from_every_light_bulb
[04:25:29] <jacekowski> hetii: fiber is almost lossless and keeps light contained
[04:26:17] <jacekowski> hetii: optics on your typical laser pointer is not good enough for data transmission
[04:26:38] <jacekowski> hetii: and air isn't great medium either
[06:46:45] <slidercrank> where do I get a symbol for gschem for Atmega8A? There is ony Atmega8 there :\
[06:50:54] <LeoNerd> slidercrank: I doubt it matters does it? The 'A' variants are usually very minor changes, like power improvements or faster max clock
[06:51:14] <slidercrank> LeoNerd, but pinout is very different
[06:51:29] <LeoNerd> Oh, hmm
[06:52:45] <slidercrank> for example, Atmega8A has the first pin as /reset. While Atmega8's pin at the same position is PD0
[07:05:10] <slidercrank> LeoNerd, I was talking about physical layout of pins. their numbers and functionality match but positions are different
[07:06:00] <slidercrank> which can be confusing (at least for me)
[08:25:20] <Haohmaru> does anyone have any experience with avr-uip?
[09:05:43] <LeoNerd> Mm.. my half-pitch pogo ISP adapter has arrived :)
[09:07:59] <LeoNerd> Now I can put ISP pads in a quarter of the board space of a full 2x3 pin header
[09:12:23] <Shavik|Work> LeoNerd, I need to look to do the same for my boards
[09:12:34] <Shavik|Work> Building around 8-10 different devices. all have the exact same form factor
[09:12:45] <Shavik|Work> So would be pretty easy to build a programming pogo based board
[09:12:51] <LeoNerd> Shavik|Work:
https://www.tindie.com/products/madworm/tiny-avr-isp-pogo-pin-programmig-adapter/
[09:12:57] <LeoNerd> The one I have
[09:13:02] <Shavik|Work> OOO
[09:13:11] <Shavik|Work> hadn't thought about one being made like that before
[09:13:18] <LeoNerd> Admittedly I didn't have time this mornign to solder it up, so I can't vouch for how well it works, but it arrived promptly and at least looks nice
[09:13:22] <Shavik|Work> I was gonna build a test jig that you drop the board on
[09:19:57] <TechChristoph_> hi
[09:21:18] <LeoNerd> Advantage of this little handheld pogo board is that it's reusable for all kinds of layouts
[09:31:07] <Jartza> LeoNerd:
https://slack-files.com/T02FEAMUS-F03E9QZ93-10761fe7d3 &
https://slack-files.com/T02FEAMUS-F03EC0BH6-4c955491b4
[09:31:17] <Jartza> that's also very useful :)
[09:31:55] <LeoNerd> Oh, cute
[09:32:06] <LeoNerd> though, I prefer pogo pins, as your board needs quite a courtyard around it
[09:32:13] <LeoNerd> I can fit the pogo pads next to other tall components
[09:38:13] <Shavik|Work> That's a nice solution Jartza
[09:38:48] <Shavik|Work> I do agree with LeoNerd's size comment. Size is an absolute premium on our boards. I probably should move to 4 layer
[09:38:55] <Shavik|Work> 2 is confusing enough in Eagle
[09:39:53] <LeoNerd> I need to find a smaller source of crystals.. my last board uses an HC49-SMD and that looks -massive-
[09:40:20] <Shavik|Work> Yea I just moved from that formfactor
[09:40:50] <Shavik|Work> I used this on my last design
[09:40:51] <Shavik|Work> http://www.mouser.com/ProductDetail/ABRACON/ABM7-20000MHZ-D2Y-T/?qs=sGAEpiMZZMsBj6bBr9Q9aSprw5Phe4pQzIz5aCxKhkc%3d
[09:41:05] <Shavik|Work> I'm really liking it so far
[09:41:13] <LeoNerd> I was looking at those... how do they hand-solder?
[09:41:25] <Shavik|Work> :/ We get our boards assembled by Screaming Circuits
[09:41:33] <LeoNerd> I don't have a spare GBP6k lying around, so I've yet to invest in soldermask/pickplace/reflow oven
[09:41:41] <LeoNerd> Ah
[09:41:48] <Shavik|Work> Time is more important than money for our company at the moment. thats always an "interesting" place to be
[09:42:02] <LeoNerd> Ah.. see, mine are just a personal hobby...
[09:42:05] <Shavik|Work> Ah
[09:42:15] <LeoNerd> Though I usually make boards in runs of 3, on the idea of keeping a spare, and selling one on Tindie
[09:42:20] <Shavik|Work> I do have to say, Sunstone/Screaming Circuits isn't always the cheapest but damn they do great work.
[09:42:25] <LeoNerd> If that one ever sells, I'll try selling more
[09:43:05] <Shavik|Work> I need to get some hobby boards made. all my time is going to actual work boards though. tis a shame
[09:43:08] <Shavik|Work> I'm envious
[11:22:00] <Jartza> LeoNerd: yeah, on very cramped boards that might not work. the adapter-board is 14x10mm big
[11:23:37] <Jartza> I'm thinking of making it even smaller
[11:24:44] <LeoNerd> I fundamentally can't make it smaller than I can solder though :)
[11:25:07] <LeoNerd> My current tech. is SOIC, SOT-23, 0603,... though I nearly let someone talk me into a QFP
[11:28:11] <Jartza> yeah
[11:28:22] <Jartza> my latest Tagsu is also 0603, soic-8 and sot23-5
[11:29:08] <Jartza> well, few bigger caps in power supply
[11:29:50] <Jartza> 1206 and 2x1210
[11:31:06] <LeoNerd> Yah; bigger caps
[11:31:17] <LeoNerd> Especially things like 10u or more
[11:32:08] <Jartza> http://www.ebay.co.uk/itm/291189507881
[11:32:38] <Jartza> just ordered those
[11:32:41] <Jartza> hopefully they are good
[11:32:56] <Jartza> the previous boxes I ordered had really lousy lids
[11:34:07] <LeoNerd> Looks good
[11:34:57] <Jartza> also the chinese small boxes didn't stick together that well
[11:36:15] <hypermagic> hello my friends
[11:36:58] <Jartza> allo
[11:37:08] <hypermagic> what's up ?
[11:37:14] <Jartza> not much
[11:44:32] <Jartza> just made a test of send-only uart code with interrupts on attiny84
[11:44:55] <LeoNerd> soft-UARTs that only send are easy enough..
[11:45:04] <LeoNerd> though bonus points if you can handle non-integer baud-rate divisions :)
[11:49:15] <Jartza> :)
[11:49:20] <Jartza> well this is just simple test
[11:49:24] <Jartza> https://gist.github.com/Jartza/9b60bdf91112ed084643
[11:49:41] <Jartza> and only using 8-bit timer as I need 16-bit for other stuff
[11:52:43] <Jartza> (and no prescaler, which would allow other baud rates too for faster clocks)
[13:50:51] <Duality> hi
[13:52:21] <Duality> been a while, but i am trying to upload some code, burning the fuses works. no errors. but when i try and upload the .hex it tells me the fuses have changed to 0x00 and asks me to turn them back to thier previous value.
[13:52:30] <Duality> any suggestions why this happens ?
[13:53:57] <malinus> Duality: hmm. Which programmer? avr-dude or atmel studio?
[13:59:42] <Duality> avrdude and usbasp
[13:59:50] <Jartza> what chip?
[13:59:56] <Duality> atmega16
[14:00:24] <Jartza> do you use internal or external osc and what speed?
[14:00:40] <Duality> internal
[14:00:54] <Jartza> with clkdiv8 or without? :)
[14:01:04] <Duality> without
[14:01:27] <Jartza> mmkay. shouldn't be a speed problem then.
[14:01:38] <Jartza> although you could still try adding "-B 4" to avrdude options
[14:02:27] <Duality> yea i tried that
[14:02:29] <malinus> hmm avrdude would spit out a connection error if reset was accidently disabled, right?
[14:02:51] <malinus> Duality: have you tried just reading the flash?
[14:03:12] <malinus> Or reading the fuses, I know you said you could burn the fuses. But it would be fun to hear.
[14:03:15] <Duality> then it tells me this: avrdude: Expected signature for ATmega16 is 1E 94 03
[14:03:31] <Jartza> hmm
[14:03:35] <Jartza> try with -B 12
[14:03:39] <Jartza> and burn the fuses again
[14:03:57] <Jartza> I had similar problems with "factory set up" attiny88 and usbasp
[14:04:18] <Duality> says that it expected a diffrent signature
[14:04:21] <Jartza> the fuses weren't burned correctly and the whole chip was in some kind of unknown state
[14:04:44] <Jartza> and I tried that command several times, after few times it got the fuses right
[14:04:44] <Duality> i will try and read the fuses
[14:08:52] <Duality> hmm trying to read it it tells me that the device signature is 0x000000
[14:09:25] <Duality> oh wait did it wrong
[14:09:39] <Duality> but it still tells me that the signature is not what it expected
[14:11:35] <malinus> I saw something similar after giving a chip reverse polarity. It might be dead. If you have any other atmega16, try with that one.
[14:12:11] <Jartza> ...and check the connections :)
[14:13:11] <Duality> wierd thing is it worked a while ago :) can't reverse polarity on my dev board :)
[14:14:45] <Duality> it seems that if i add -B1 it displays the fuses
[14:14:54] <Duality> which are what i set them too
[14:15:57] <Jartza> hmm
[14:16:09] <Jartza> -B1 I think doesn't do anything :)
[14:16:23] <Duality> yea
[14:16:52] <Duality> i don't know without it doesn't work with it it works. but uploading a .hex fails with fuses changed
[14:17:13] <Duality> anyway the chip isn't reliable
[14:17:29] <Duality> i'll throw it out. and us a different one. thanks for helping !
[14:17:40] <Jartza> what are the fuse settings btw?
[14:21:47] <Duality> -U lfuse:w:0xa4:m -U hfuse:w:0xd8:m
[14:22:19] <Duality> my atmega32 just works :)
[14:23:42] <Jartza> it's atmega16, not 16a/hva/hvb?
[14:24:38] <Duality> it's an atmega16 says on the chip :) but it's from china
[14:25:18] <Jartza> ohh
[14:25:22] <Jartza> chinese atmega :(
[14:25:31] <Jartza> anyway, the fuses look good too
[14:26:30] <ananda> hmmm there is some defect thing from china
[14:26:46] <malinus> No! where?
[14:28:01] <Duality> hmm trying to upload the .hex to my atmega32 and it also says the fuses are 0
[14:31:15] <Duality> think my usbasp is broken
[14:31:21] <Duality> it all went fine with my usbtiny
[14:31:55] <malinus> should have bought the Tom_itx's MKII copy :P
[14:32:14] <Duality> where ?
[14:34:27] <malinus> Duality:
http://tom-itx.no-ip.biz:81/~webpage/commerce/commerce_index.php
[14:34:36] <malinus> I've been using it for a few years now :3
[14:36:11] <Duality> aaannd
[14:36:13] <Jartza> hmmh
[14:36:15] <Duality> i just bought it :)
[14:36:24] <Jartza> I bought some chinese cheap usbasp-programmers.
[14:36:29] <Jartza> they had baaaaad firmware
[14:36:41] <Jartza> so I used one to first update other with good firmware
[14:36:44] <Jartza> took like 20 tries
[14:36:52] <Jartza> after I got one working, I updated all of them :D
[14:36:55] <Jartza> now they are fine
[14:37:07] <hypermagic> well i build a parallel port programmer and it "works"
[14:37:20] <hypermagic> it is possible
[14:37:32] <Duality> i have no parallel port on my laptop
[14:38:05] <hypermagic> but you get a junk computer and it has one, and you can program your usb programmer if you want :P
[14:38:46] <twnqx> i have a usbasp clone a friend makes, a jtag mk1 clone, and a stk600... can't have enough diversity
[14:38:52] <Duality> i have a usbtiny, but i bought my usbasp for the higher memory ranges
[14:38:53] <hypermagic> it sux pc lacks any control ports.
[14:39:15] <twnqx> it has usb
[14:39:18] <twnqx> what more do you need?
[14:39:25] <hypermagic> usb is stupid and useless
[14:39:33] <hypermagic> well gpio ?
[14:39:37] <hypermagic> adc dac ?
[14:39:45] <hypermagic> and real time interface
[14:39:45] <twnqx> all available on usb
[14:39:56] <twnqx> just a small latency
[14:40:06] <hypermagic> 1ns would be fine
[14:40:48] <hypermagic> usb also needs failsafe.
[14:41:09] <hypermagic> what if it simply dies
[14:48:54] <neionz> so I have this circuit that, when the on-switch (completes the circuit) is on, it makes a bark-sound and spins a motor. I just realized that I want an on-LED indicator. If I just connect a resistor and a LED in parallel with my circuit, will it affect the rest of my circuit?
[14:49:27] <hypermagic> yes
[14:49:40] <neionz> hypermagic: how?
[14:49:54] <hypermagic> it will discharge the holdup capacitor faster when you pull the power off
[14:50:38] <neionz> I didn't know I had a holdup capacitor. What's that?
[14:50:56] <malinus> neionz: show your circuit. but no, it will probably not affect the circuit, if you are already powering a motor with it?
[14:51:00] <hypermagic> well you should
[14:51:17] <malinus> neionz: show schematic
[14:57:10] <neionz> malinus:
http://draw.to/D1tTpxs
[14:58:08] <malinus> looks fine to me
[14:58:47] <neionz> so the added LED has no effect on the circuit? :3, except that more amps are pulled out of the battery?
[15:03:20] <Duality> yea it was moste definitaly the programmer the atmega16 still works! :)
[15:13:11] <neionz> when you design logic schemes (say, with transistors), do you still assume that the signal is propagating the wrong way?
[15:15:57] <hypermagic> yes
[15:16:17] <hypermagic> this is why they match the transmission line impedance
[15:16:19] <neionz> I don't know why I'm finding that depressing
[15:17:56] <aep> any opinions on the avr dragon vs jtagice3 ? i got both and i'm going to return one of them
[15:17:56] <hypermagic> http://en.wikipedia.org/wiki/Impedance_matching
[15:17:59] <neionz> hypermagic: "they"?
[15:18:19] <hypermagic> http://en.wikipedia.org/wiki/Reflections_of_signals_on_conducting_lines
[15:18:46] <hypermagic> yea usually you buy stuff that is matched and plug together
[15:24:24] <neionz> hypermagic: what does that have to do with the direction that logic signals are propagating?
[15:30:27] <RikusW> everything at high speeds
[15:30:34] <RikusW> its rf then
[15:47:40] <apo_> ... There's an LM324N stuck to my shoe. Wonder if that's one of mine...
[15:50:19] <hypermagic> oh those dead bugs ... they can stick in your slippers
[15:52:56] <Jartza> yay
[15:53:15] <Jartza> now my attiny84 uart with interrupts pushes data out @460800bps
[15:53:20] <Jartza> with 16MHz clock
[15:53:21] <Jartza> yay
[15:54:14] <neionz> do you guys have any general opinion about getting components from old devices, such as old computers etc?
[15:55:49] <Jartza> if it works, why not
[15:55:58] <Jartza> I've salvaged a lot of parts
[15:56:18] <Jartza> it always beats waiting for some component delivery (as I don't have any component stores nearby)
[16:00:03] <hypermagic> motherboards used to have transistors, capacitors
[16:00:11] <hypermagic> some useful stuff
[16:00:27] <hypermagic> and old power supplies
[16:08:21] <jkmel> i have a problem. im using mcp73831 lipo charger in a circuit with xmega, id like to interface the chargers status pin to the xmega, hoeever the pin goes slmost up to 5v when high... xmega is not 5v tolerant? or is a series resistor enough? the pin is also 3state so i need to use a pullup i guess
[16:08:53] <hypermagic> resist it ?
[16:09:19] <hypermagic> or level translate
[16:10:04] <jkmel> well i really dont wanna stick a level shifter just because of that
[16:10:45] <jkmel> juat wondering whwther a series resistor is enough...
[16:10:49] <jkmel> just
[16:11:18] <Tom_itx> level shifter is nearly as cheap as 8 r's
[16:12:02] <Tom_itx> resistor would probably work
[16:12:31] <Tom_itx> GTL2003PW
[16:12:39] <Tom_itx> is a good level shifter
[16:12:47] <Tom_itx> comes in 2 to many bit wide
[16:12:57] <neionz> so I want to power my AVR-raspberry pi with a 9V battery. But I can't just connect the battery to the raspi in series with a resistor since the resistance of the raspi will vary?
[16:13:39] <Tom_itx> wtf?
[16:13:46] <Tom_itx> you need a regulator for that
[16:14:30] <jkmel> tom i know. thats the only application in which i might need it so i dont see the point of using it
[16:15:17] <jkmel> i guess the xmega has clamps
[16:17:23] <vsync_> fucking hate xmegas
[16:17:31] <vsync_> is that like a dead line or what
[17:03:35] <hypermagic> xmega are cool, they have dac and events
[17:19:31] <neionz> theoretically (not going to.. just doing theory), if I divide 9V into 4 and 5V over R1 and R2, and tries to power a raspberry pi by parallel coupling it with R2, that the pi can't draw so much current that it'll burn? Rather, the voltage will just drop over rpi and R2 (since rpi and R2 in parallel gives less resistance) giving R1 an even higher voltage drop. And as said, R1 sets the upper limit of how much current that can be drawn too.
[17:19:42] <neionz> it's AVR related, but I'm too lazy to rephrase the details
[17:34:54] <Jartza> neionz: raspberry pi uses 1.89 Watts
[17:37:20] <malinus> neionz: you can't use a voltage divider if you want to draw current.
[17:37:43] <neionz> malinus: why not?
[17:41:31] <malinus> neionz: I suggest reading a book. Or at least the first chapter from
http://www.ibiblio.org/kuphaldt/electricCircuits/
[17:42:35] <neionz> thanks, I will
[17:45:44] <vsync_> last night audio signals, today voltage regulation
[17:46:40] <vsync_> you can't regulate the voltage like that
[17:47:21] <vsync_> it's not meant to drive loads, really. if your load is fixed you can calculate that into it but that's not the case here
[17:49:37] <vsync_> just use a voltage reg or better yet, use an mcu to build an smps like that silly arab, can't remember his name...
[17:52:14] <malinus> obama?
[17:54:46] <neionz> the guy who fries himself all the time?
[18:09:22] <malinus> I remember the guy who asked about main in breadboard, and showed a picture. Then we never heard of him again
[18:09:25] <malinus> rip
[18:14:03] <Tom_itx> some are more the 'hands on' learning type
[18:16:20] <neionz> in the lower circuit, parallel lamps (no matter how many, in theory at least) will all get 5V. If you however add the dotted component in the higher circuit, the 3V will drop to something less. Now why is this discrimination taking place?
[18:27:10] <vsync_> um
[18:27:13] <vsync_> wtf is the reference?
[18:32:01] <neionz> would you buy these?

[18:32:19] <neionz> vsync_: I forgot the link :3

[18:55:32] <vsync_> breadboards are handy sure
[18:55:44] <vsync_> for ultra fast testing stuff out
[18:59:39] <vsync_> huh?
[18:59:51] <vsync_> um what part of that don't you understand?
[19:01:13] <vsync_> you have to think of the two in parallel
[19:04:34] <vsync_> nrf8001 pin arrangement sucks ass
[19:17:38] <aandrew> heh
[19:17:42] <aandrew> it's not THAT bad
[19:17:51] <aandrew> I hate the exposed pad on the nRF51822
[19:18:08] <aandrew> all my RF sections are done with 0402 components for space and that's tedious to place by hand
[19:18:18] <aandrew> the esp8266 pinout is kind of crappy for routing too
[19:18:20] <aandrew> another exposed pad
[19:36:13] <vsync_> we'll see the viability of this
[19:36:48] <vsync_> rf is like black magic, really.
[20:31:01] <hypermagic> Jartza, more like 5W
[20:57:01] <hypermagic> neiget a pc power supply, or an usb charger and you have 5V.
