I have followed the instructions in the data sheet and tried to generate PWM signal using PIC16F628A. However it seems to be not generating any output. My code is shown below. Any help appreciated regarding finding the what is wrong in my code.
PROCESSOR '16F628A' INCLUDE <P16F628A.INC> org 0x00 bcf STATUS,RP1 bsf STATUS,RP0 ; go to bank1 movlw 0xff ;255 dec movwf PR2 ; writing to PR2 register bcf TRISB,3 ; set RB3 as output bcf STATUS,RP0 ; go to bank0 bcf CCP1CON,5 ; clearing bits 5 and 4 bcf CCP1CON,4 movlw 0x00 movwf CCPR1L ; set duty cycle bcf T2CON,1 bcf T2CON,0 ; set pre-scaler to 1 bsf T2CON,2 ; enable Timer2 bsf CCP1CON,3 bsf CCP1CON,2 ; enable pwm mode return end
