| Thanks again very much for the answer!
I tried the code again and it works fine, however I'm not yet satisfied with the resolution of the PWM signal. With a 10 KHz interrupt rate and a 50 Hz period ... |

| Thank you very much for you answer PCM programmer!
I tried the long_delay_us function and it works really fine! However, if I'll be able get the soft PWM running, I can write a program without the ... |

| Hello,
I use an PIC16F877 @ 4 MHz and want to control two servo motors with it. I'm afraid I can't use the PWM module at less than ca. 250 Hz (244.14 Hz when PR2=0b11111111) However, I need a PWM ... |

| Thank you for your answer Ttelmah.
It tried the following code and only the LED at the RC2/CCP1 pin was blinking, no signal at RC1/T1OSI/CCP2 
#include <16F877.h> #fuses XT,NOWDT,N ... |

| Hello everybody!
I'm new here and this is my first problem: I want to generate two PWM signals with my PIC16F877. Therefore I use the following code. To check the PWM signals (CCP1 and CCP2) I hav ... |
