Let me see what I can do. . .

Our pressure switch code is wicked simple:

The pressure switch is on digital input 8, and the compressor is on relay 8.

in the initialization routine

relay8_fwd = 1; //Start with compressor on


In the default routine:

if(!rc_dig_in18)
{
relay8_fwd = 1; // If low air pressure, turn on
}else{
relay8_fwd = 0; // If high air pressure, turn off
}
