Plz give me working of timers in PIC16F676

[Vishal Raut]

I am using timer0 in PIC 16F676 for PWM generation. I am giving the steps i followed for the general controller initialization and interrupt initialization. Its not working well. i have to made power ON/OFF several times then PWM generation starts,the part before interrrupt initialization is working well.I am also using ADC but without interrupts.I am using internal osc. without clk,MCLRE disabled.Plz also give how to write configuration bits in MPLAB software,ITS HURRY, Thanks.

Deuh, sure it's not your whole program....

and your condif fuse line MUST looks like

__CONFIG  _INTRC_OSC_NOCLKOUT & _CPD_OFF & _CP_OFF & _BODEN_OFF & _PWRTE_ON & _WDT_OFF

Thanks friends for giving attention on my thread.I am feeling very happy to say that i have got the solutions from microchip pdf files and prog is working nicely.
