hi, my interrupts on change cant work, temp is always is zero...
input for
#define X_IN input(pin_b5)
#define Y_IN input(pin_b6)
is PWM, how to get it work?
compiler=v3.249

#FUSES NOCPD //No EE protection
#FUSES BROWNOUT //Reset when brownout detected
#FUSES NOIESO //Internal External Switch Over mode disabled
#FUSES NOFCMEN //Fail-safe clock monitor disabled
#FUSES NODEBUG //No Debug mode for ICD
