first: yes, i've read the avr-libc FAQ, and i've read bruce lightner's web page, and i've downloaded his code, and i can build his test programs. so i believe that if i were doing a project with the ATtiny15, that i could code it in (a subset of) C.
but i'm not. :-)
i'm using the ATtiny13. before i attempt this work myself, has anyone else take bruce lightner's work, and extended it to support the ATtiny13? i suspect i could use it as-is if i were willing to give up using the SRAM, but that seems sort of silly, so i'll probably see what i can do to make it better. but i'd rather start where someone else left off, if possible...
