Outsourcing PWM comtrol
Its rather straight forward to drive up to 8 hobby servos. Just need a small ISR (5 lines of c code), and a function in the main loop of the program that is called at least every...

Have you disabled the JTAG fuse? its enabled by default from factory.

driving multiple servos?
Depends on what sort of servos your using, you wouldn't want anything less than 8 bit resolution normally, but if you're using expensive servos that are high speed and much more...

[solved]CTC interrupt general question
Great, it works! From what knutbr said, all I did was put it in normal mode (as opposed to CTC mode), and it worked. No more clearing of the timer. Thats saved a major headache....

[solved]CTC interrupt general question
Yea just looking at the data sheet, and it seems its possible. If the CTC interrupt is disabled, I could poll the Output Compare Flag (OCFnx) in normal mode, and hence high CPU...

strange char array parsing problem
Ok, I got it, thanks glitch for pointing me in the correct direction. It was looking for it in RAM. I used this tutorial on PROGMEM here to fix it. Its working like a dream now....

strange char array parsing problem
Yes its compiling for a atmega644p, here is my make file below. I reinstalled the lasted version of winavr to get 644p support. It compiles without any errors or warnings. main...

help getting EM-406A GPS data into a ATMEGA32
Try setting the UBRRH, and UBRRL bytes at the end of your initialization code after you've set all the other settings. Thats how I got mine working. I did a simulation in Avr...

[TUT] [C] Newbie's Guide to AVR Timers
Thanks for the great tutorial. Using your tutorial alone, I've just wrote my very first interrupt implementation, to drive a servo with PWM signal in software, on a atmega8....

Max current draw from multiple IO pins
Yea you should be able to. On a uni project I did last year we had 8x 5mm LED's connected to IO on a atmega8, and they take like 20mA each.
