AVR GCC and variable sizes
Remember that the AVRs do not have 16 bit load or store instructions. Therefore, if you have a 16 bit counter, for example, which is modified by an interrupt, any reference to...

printf to UART
Search for the fdevopen() function. It lets you set default input and output streams. I don't have the details to hand right now, but I've used it to printf to the UART and to...

registers r00 to r15
All registers are not equal, if you check the AVR instruction set you'll find that LDI can only be used with registers 16 - 31. Also, oxff will almost certainly cause problems;...

random number generation when using ATMEGA 32L
If both(all) of your devices are identical and have identical code, they're going to produce the same pseudo random number sequence. You cannot produce truly random numbers with...
