Hi
I try make a little example with this PIC12F683 with internal clock but it don't work...
| Quote: |
#include <12F683.h>
#use delay(clock=4000000)
#fuses NOWDT,INTRC_IO, NOCPD, NOPROTECT, MCLR, NOPUT, BROWNOUT, IESO, FCMEN
void main()
{
while(TRUE)
{
output_high(PIN_A0); //pin number 7
delay_ms(1000);
output_low(PIN_A0);
delay_ms(1000);
}
}
|
I have on PIN_A0 one LED.
some one can help me?
regards  |

Post your compiler version. It's a 4-digit number in this format: x.xxx
It's given at the top of the .LST file. The .LST file is in your project directory. |

Obvious comments apply though:
Hopefully you have a pull up on the MCLR input.
Series resistor to the LED.
Best Wishes |

| If I am not mistaken, the GPIO pins 0-3 default to analog inputs. They must be specifically set to digital I/O with a set up function. I don't have access to my compiler just now, but look at the setup functions in the help files and the appropriate parameters in the 12F683.h files. |
