General Information about Inputs/Outputs

The iLCD Controllers allow most port pins to be assigned as digital or analog inputs, outputs (pull down or push/pull) or keyboard columns via iLCD Manager XE. All commands referring to port pins below refer to the logical port name, not the physical port pin name.

This means the physical port pin "Keyboard column 3" may have the logical name e.g. "Output #9", so turning on this pin (= setting it to high when it is defined as a push/pull pin) can be done via the Set Output command like this:

\i I L S 09H 01H

When using the same port as a pull-down output port, sending the above command pulls the pin to low (making it "active") instead. Note that the Color iLCD Controllers can only source/sink 4mA. Please check the documentation for your particular board.
