| Thanks, i found the problem.
I tried with simpler code and it worked without any problems. So i went thru the code and found this line: "setup_counters(RTCC_INTERNAL, RTCC_DIV_8);" whic ... |

| Timer0 is 8 bits wide in the 16F877. It can optionally be 8 or 16 bits
wide in the 18F4620. Look in the Timer0 section of the 18F4620.h header file to see the constant for setup_timer_0() that co ... |

| Here is an improved program that will give a 50 Hz pwm update rate,
and allow 100 pwm steps. #include <16F877.H> #fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP #use delay(clock = ... |
