Hi,
I am trying to use the PCINT0 interrupt on the Atmega88 chip but an unable to get it working. i want it to work for pin number 12, 13 and 14 ie PCINT0, PCINT1 and PCINT2 respectively.
i am initializing it as
main(){ PCIFR = 0X01; PCMSK0 = 0X07; Sei(); }
AND
ISR(PCINT0_vect){ send_byte(1); }
The ISR is not getting fired using only this code. Am i missing out on some initialization. Kindly help me out.
Thanks, Rohan.
