ReadPinValue
ReadPort
Reads the specified pin.
Reads the specified pin and returns the value as the return value. If the pin has been configured as a
digital input, the return value will be either ‘
of 0x8000.
Must be previously configured as an input via a
VID and PID must be previously set via a call to

This function returns the read value of the pin, or returns a value of 0x8000, if an error occurs.
None.
Reads the GPIO port as digital input.
Reads the GPIO port and returns the value in

This function returns True if the transmission is successful and returns False if the transmission fails.
Pins configured for output return the current state of the port. Pins configured as input read as zero.
