Parameter
Method
Type
Description
pin
ByVal
Byte
The pin to read.
Discussion
If the specified pin is configured to be an input, this function reads the state of the pin and returns the
value 0 or 1 corresponding to logic zero and logic one. If the pin number is invalid the result is undefined.
If the pin is configured to be an output, it is reconfigured to be an input in tri-state mode before reading
the input value.
Compatibility
The BasicX documentation says that the result is undefined if GetPin() is called for a pin that is
configured as an output. Tests show that the pin is actually reconfigured to be an input in tri-state mode.
The ZBasic implementation of GetPin() does the same.
