I/O support

Digital I/O line support

Digital I/O is available on lines DIO0 through DIO12 (D0 - D9 and P0 - P2). Each of these pins may be
configured as 3, 4, or 5 with the following meanings:
3 is digital input
n
4 is digital output low
n
5 is digital output high
n

Analog input

Analog input is available on D0 through D3. To use analog input, set these parameters to 2.

Monitor I/O lines

You can use IS command
no inputs are defined, the command returns an ERROR.
If you send the IS command from Command mode, then the device returns a carriage return delimited
list containing the following fields.
