I have one routine that defines an LED & sets it. Another routine needs to make an LED adjustment, but the name (redled) is not recognized there (a scope problem). I know I can define it outside of both routines, but then it seems EVERY control, ports, etc would have to be defined at “the top” of the program—is that the proper way to go about it? most books do not address this, they only show one routine…I need to control leds, ports, etc from several routines.
public static void ControlPanelSetup()
{ // code
// more code
// more code here
OutputPort redLED = new OutputPort((Cpu.Pin)FEZ_Pin.Digital.LED, false);
// more code
redLED.Write(true); //turn led on
//more code
//more code
}
public static void AdjustLeds()
{
//code
//code
redled.Write(false); // turn off led ERROR HERE redled unknown
// more code
}
