Thankx HenrikOlsson for the comments, and explaination to me
I have been worked on this code for the whole day but still I didi not get any output. The problem I faced is I don't get any output to the CCP1(TRISC<2>).I tryt to put led1 on main to measure the time I get it clear which is 1sec for each toggle which is true( 500+500)ms also I put led1 on UpdateDuty subroutine also I get clear a delay of 500ms to each toggle which is also true because UpdateDuty it is called aftter every 500ms. But I 'm confusing where is problem? And why is CCP1 does not output to (TRISC<2>)?.Here is the code.
Help me to solve this problem thankx.Code:PIC 16F877 define OSC 4 TRISC = %11111011 CCP1CON = %00001100 T2CON = %00000100 PR2 = 199 for 5khz TRISB = %11111101 TRISA = %11111111 LED1 VAR PORTB.1 temp var word Main: Temp = 40 GOSUB UpdateDuty Pause 500 Temp = 400 GOSUB UpdateDuty Pause 500 TOGGLE LED1 GOTO Main UpdateDuty: CCP1CON.4 = Temp.0 ' bit 0 CCP1CON.5 = Temp.1 ' bit 1 CCPR1L = Temp>>2 'Bit 2-7 RETURN end
