Turning on LED using PropGCC

Just wondering how I can turn on an LED using the GCC in simpleIDE.

thanks

There are no built in functions for this, not sure why. You have to include <propeller.h> in your program. It would also help if you show us your code, meaning, what have you tried so far.

Ray

#include <propeller.h>

void high(int WCpin)
{
    unsigned int bits = 1 << WCpin;
    DIRA |= bits;
    OUTA |= bits;
}

void low(int WCpin)
{
    unsigned int mask = 1 << WCpin;
    DIRA |= mask;
    OUTA &= ~mask;
}

I must of scared the OP with my terse answer, so here is how it is done.

Ray

/**
 * @file basicLED.c
 * This is the main basicLED program start point.
 */
#include <propeller.h>


void high(int WCpin)
{
    unsigned int bits = 1 << WCpin;
    DIRA |= bits;
    OUTA |= bits;
}

void low(int WCpin)
{
    unsigned int mask = 1 << WCpin;
    DIRA |= mask;
    OUTA &= ~mask;
}

/**
 * Main program function.
 */
int main(void)
{
    high(0);
    sleep(1);
    low(0);
    high(1);
    sleep(1);
    low(1);
    return 0;
}
