moving all initialized data and strings to program memory
i know this topic is well covered in the avr-libc docs, but i've come up with a technique that i haven't seen written up before, and thought i'd share it -- in case someone else...

iom32u4.h for ATmega32U4 incorrectly defines Timer 2
it's my understanding from the datasheet that the atmega32u4 doesn't have a Timer 2, so it seems like the definitions for TCCR2A, TIFR2, TCNT2, etc, should be missing from the...

can pins be ganged for higher current?
are the pin drivers on any single chip closely matched enough that running them in parallel in order to drive higher current loads is practical? in particular, i'd like to hook up...

easy TXD invert on 2313?
since i've now implemented it the hard way, i figure i should ask if there's an easy way. for my avrlirc IR receiver project, i wanted to eliminate the MAX233 requirement, and to...

STK500-style jumpers: digikey part no?
my digikey catalog search skills are failing me. i want to make up some jumpers similar to the twin-lead jumpers that come with the STK-500 -- the ones that fit over a pair of 0.1...

115 Kbaud possible with internal RC osc?
can one get reasonably reliable 115200 baud from an ATTiny2313 running on the internal 8Mhz oscillator? the datasheet (in table 58) lists 3.5% error (and that's using the 8...

ATtiny13 and avr-gcc
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...
