| Thanks PCM programmer for the help, I actually left the master clear pin not connected , So I was having problem in getting the pwm, Now I have corrected it and its working fine
Many Thanks Quium |

| Hi
I have tested my circuit by giving an external PWM instead of generating a PWM from the PIC and the circuit was working fine. |

| Hi
I have made alterations in the fuse setting changed to HS mode and the resonator as advised by you but still I did not manage to get the required PWM. Many Thanks |

| So in that case I have to remove the 12Pf capacitors that I have connected and then change the fuse setting to HS mode and hopefuly with my above codes I will be able to get a PWM of 50KHz.
Sorry f ... |

| I have done the calculation and I am getting the value of pr2 as 19 which is with in the range of 0-255, So I think I can use the 4MHz to get a pwm of 50KHz. | |
