  • Switch

This program reads the digital input state.

ReadBit.py

import emant m = emant.Emant300() m.Open("00:06:66:00:a1:D8") print m.HwId() print m.ReadDigitalBit(3) m.Close()

Code Explained

print m.ReadDigitalBit(3)

The ReadDigitalBit method returns a boolean value reflecting the switch status (True/False). As the switch is normally open and there is a pull up resistor on the digital input, a True will represent an unpressed switch.
