Hi, im trying to use a timer interrupt to trigger the interrupt service routine and read a value from the ADC. however when trying to compile the ISR doesnt like to call any functions and spits an error at me.

any help woule be appreciated.

its a 16F876 btw.

Which Pic are you using?
I did something similar. It took the voltage from the LDR run that through an ADC, scaled the value to MIDI range(0-127), then displayed the value on the LED's.

I can send you a copy of the code if you'd like?
