Easy C Relay Programming

[Imajie]

You want the relay to toggle. Its not too complicated to do.
This example will toggle a relay when the trigger is pulled on the first joystick.

char relayPos = 0;    //Holds the current position of the relay
char relayRelease = 1;    //Holds if trigger has been released yet
if(GetOIDInput(1, 1) && relayRelease)    //If trigger is pressed after being released
{
    if(relayPos == 1)
    {
        SetRelay(1, 0, 1);
        relayPos = 0;
    }else
    {
        SetRelay(1, 1, 0);
        relayPos = 1;
    }
    relayRelease = 0;    //Set trigger as pressed
}else if(GetOIDInput(1, 1)==0)    //trigger released
{
    relayRelease = 1;
}

Note that the above is for a double solenoid. If you are using a single solenoid then change the SetRelays to SetRelay(1, 0, 0) and SetRelay(1, 1, 0)
