klaus,
1. I already attached my development board.
2. I want to decode IR remote of NEC protocol. For that I got a code from web. While testing the code i found that interrupt part is not working. Then i decided to test the interrupt with a simple LED blinking code. It works well in simulator but the while doing the same in harware found that same interrupt part is not working.
3. when you apply voltage to MC PORT A LED goes high as written in code, but when i applied interrupt at B0, it doesn't blinking.
4. I tried to add/modify register of INTCON, OPTION_REG, and even OSCCON for setting internal oscillator. Nothing works so far.....
also added 10k resister to B0 to ground.
