Re: PIC18F452 External INT0 problems
Yes, it just a bit of long story...
I am working on original project based on PIC18F14K50 /C18 - DC motor controller with constant speed ( optical sensor feed with PID ) . Project is developed by some person and not being continued or supported anymore. It is very well developed project (SW and HW), though there are few issues with code there - few bugs that I was trying to fix. Unfortunately debugging of 14K50 is complicated/expensive and I decided to port code to PIC18F254 with minimal changes, debug it, and than backport it. I have already ported and made majority of the critical code, including Timer0 interrupt, ADC piece and PWM generation. I just stuck with External interrupt routine that receiving optical pulses from encoder.
Any help will be appreciated.
