| A question about ECCP[Solved] |

Does PWM frequency reduce in ECCP mode?
I calculated the PWM frequency as 20 Khz.
I wrote this code shown below. But I get 5khz signal at the output of the P1D. Is it normal?
My codes; (My compiler version is 4.114)
| Code: |
#include <18f14k50.h>
#include <PIC18f14k50_registers.h>
#FUSES NOWDT,INTRC_IO,NOPUT,NOBROWNOUT,NOLVP,NOCPD,NOMCLR,NODEBUG
#use delay(clock=4000000)
void main()
{
TRISC=0b00000010;
PORTC=0;
t2con=0b00000100;
ccp1con=0b00001100;
pstrcon=0b00001000;
pr2=50;
CCPR1L=10;
while(true){}
}

Thanks

1) Is this a real chip with a 'scope looking at the signal or a simulation(proteus ?)?
2) you should use the CCS functions for setting peripherals up, I doubt many will want to take the time to figure out what ,for example...ccp1con=0b00001100 translates to. |

| Ok I solved. It is all about my PIC programmer. Thanks for consideration. |

I don't know how to setup ECCP module.
Can you give me a sample program or help me setup this? |

1. What ECCP mode do you want ? Full-Bridge, or Half-Bridge, or what ?
2. What is your CCS compiler version ? |
