The current requirement is that I read the value of a single DI channel of the DIO module to trigger the action of DO, or read the value of a single channel of AIO, and there is a write to the AO channel
We use piTest -r variable name, What type is the return value of a single variable and how to use this return value to drive piTest -w variable name Value
It is that
if (piTest -r variable name)
piTest -w variable name value
How to write it?
