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...

assembler directives used by GCC
Many thanks for the link to the pseudo ops info. Re. my second question, it is the output OF the ASSEMBLER that I wnted to view, not the the assembler output from the compiler.

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...

Caller- and Calle-save registers in ATMEL AT90LS8535
Do you mean in the context of a C compiler?, if so, it will depend on the particular compiler. The only register that is AUTOMATICALLY saved when a call is executed on an AVR is...
