Nordic RF antdefines.h
Anyone have a copy of antdefines.h ? I've searched in vain on the web, looks like Nordic now require you to spend $399 on a dev kit before you can register, which is pretty steep...

Crystal oscillator startup confusion.
I have a program(ATTiny24) that uses the input capture feature on Timer/Counter 1. I'm timing IR remote pulses, as it happens, while trying to keep power consumption to a minimum...

Harvesting power from headphone output.
Anyone have any ideas about the viability of stealing enough power from an iPod headphone jack to power an AVR that spends most of its time sleeping? There are chips available...

STK500 command line fuse word, big-endian or little-endian?
Well, the subject says it all, I think. If I use skt500.exe to program my Mega640, the command line switches want a 16 bit hex value for fuses. Is this lttle-endian or big-endian...

Communicating via CAN protocol.
I estimate that 74% of the times one see a picture like this, the participants are not keeping the string taut. This sort of thing really irritates me....

Looking for M128 or M1281 proto board(3.3V)
I'm trying to find a header PCB/breakout board or whatever you choose to call it, for a Mega128(1) that will run at 3V3. I've looked through the offerings from Olimex, Sparkfun...

Measure supply voltage on ATtiny24
Am I right in thinking that I can check the supply voltage(battery) on my ATTiny24 circuit by setting Aref to Vcc and selecting the internal reference as the input channel? And...

14 pin SOIC adapter for STK600
Does anyone make a 14 pin SOIC adapter for the STK600? I may need to program some ATtiny24/44/84 parts, and the final PCB is likely to be too tight on space for an ISP connector,...

Small problem with volatile.
I have 3 or four 16 bit variables that are used as timers. Because they are decremented to zero(and not below) in an ISR, they are declared as volatile. The problem I have is that...

JTAG versus ISP
Here's a simple question that I could probably answer by reading datasheets. I may shortly have the luxury, for the first time in my life, of using JTAG(JTAG ICEMKII) for a...

Persuading GCC to put my asm fonts/strings in low 64K of 128
As I understand things, GCC will attempt to place PROGMEM stuff in the lower 64K of an Mega1281's FLASH memory. My program has, for efficiency reasons, a couple of fonts and some...
