Hi guys,
I found out the problem already! My programming is okay, but there is problem for my PIC fuses. Thanks. |

I changed the PIC already. And I have checked there's 5v in the PIC. However, there is zero voltage at CCP1 pin. How can I get the correct PWM duty cycle? |

Post a SHORT section of compilable code which shows the problem. I.e. less that a screen-full with your version No.
You are making us second guess at the cause. From your code it should be obvious. ... |

I am currently using PIC16F648A. I have succeeded to build my programming code. However, I can't detect any signal from pin B3 (ccp1) directly from my probe. Maybe I know what is the reason that this ... |

So I should write like that, right? Please refer to the bold part.
#include <16F648A.h>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)
main()
{
outp ... |

I am sorry. I am using PIC16F648A and my oscillator frequency is 4MHz. I would like to generate a 25 kHz PWM signal. |
