Martin,

Your code is for 8 bit parts you need to work with
16 bit values. like  TRISB = 0x0000; PORTB = 0xFFFF; etc

Subject: [PIC] Unable to get C program to work


I'm trying to write an extremely simple program for a 30F3010 using the
Microchip C30 tool. This is my entire program:

#include <p30f3010.h>

void init()
{
    TRISB = 0x00;

    return;
}

void delay()
{
    int x=0;
    for(x=0;x<10000;x++){}
    return;
}

int main (void)
{
    init();
    while (1)
    {
        PORTB = 0xFF;
        delay();
        PORTB = 0x00;
        delay();
    }
   return 0;
}

I don't know how it could be much simpler. It compiles, I program it with my
USBProg, and nothing happens.
I have set the oscillator to Internal RC - High Speed and the WDT is off. I
attach an oscilloscope and it's dead as can be. I've tried clocking it
externally with a function generator and I get the same thing. Yesterday I
tried an 18F1220 with nearly the same exact program and the clock seems to
run for a few ms and then quit. I'm getting really frustrated with how much
time I'm wasting trying to get my dev. tools to work. Do you have any
advice?
Thanks,
