Helios Portctrl : A library for easy utilization of the Helios PC/104 GPIO pins

Descriptions

This is a small C library I made to help with my embedded systems classes to have easy access to the Helios PC/104's GPIO pins when developing for QNX Neutrino.

Example Program

A simple blinky program for blinking 2 LEDs:

int main(void) {
    int i;
    if (initIOCtrl() == FAILEDPERMISSION){
        return;
    }

    setPort(PORTA, IN);
    setPort(PORTB, OUT);
        
    while (1){
        for(i=0; i < 10000; i++);
        pinOn(PORTB, PIN0);
        
        if(readPin(PORTA, PIN0))
            pinOn(PORTB, PIN1);
        
        for(i=0; i < 10000; i++);
        pinOff(PORTB, PIN0);
        
        pinOff(PORTB, PIN1);
    }
}
