Helps on P18f2520(PWM)

Hi all. I am new here.I would like to ask why my PWM program does not work. FYI, i am using MPLAB, ICD2 complier and crystal oscillator is 8Mhz. Here my code:

#include<p18f2520.h>
#include<delays.h>

void main(){

TRISC=0b11011111; // RC5 as output
T2CON=0b00000111; //prescaler=16
CCP1CON=0b00011100;

while(1){

PR2=0b01111100; //1Khz
CCPR1L=0b00111110;
Delay100TCYx(200);
Delay100TCYx(200);
Delay100TCYx(200);


PR2=0b00011000; //5Khz
CCPR1L=0b00001100;
Delay100TCYx(200);
Delay100TCYx(200);
Delay100TCYx(200);


}
}


I hope some kind souls can help me with this code.Tell me what goes wrong and where is the problem.

Thanks in advance.--- God bless you.
 

.

what configuration have you used for the pic?

Added after 19 minutes:

wait a minute the the CCP1 output is RC2 which you have set as input.

TRISC=0b11011011; // RC5 and RC2 as output

and it works perfectly

Thanks a lot..I will try now..

Thanks...it works.

Do you have any idea on how to initialize a 8 bits serial port LCD(LASCAR sp5-gfx1)?
 

I am glad it works, This lcd that you mentioned uses SPI, if you search for it you will get many examples. some other graphic LCD's also use it. the best advise is to check the datasheet for this LCD
