Python control library for Numato relay hardware.
Originally built as a basic monitor and control tool for the Numato 2 Channel USB Relay Module, it should be usable on almost any Numato USB device that uses the same serial command scheme.
Currently supports retrieving status and writing to any relay on the device.
Supports Python versions between 2.7.x and 3.4
(Due to use of the enum34 library)
Later versions of Python should work with the built in enums.
Example Use:
# Defaults to port /dev/ttyACM0
from numato.numato_controller import numato_controller
device = numato_controller()
device.get_relay_state(0) # Retrieve state of relay index 0
<RelayState.RELAY_OFF: (0, 'off')>
device.turn_on_relay(0) # Turn on relay index 0
device.write_relay_state(relay_index=1, new_state=0) # Turning off relay index 1
device.get_relay_state(0)
<RelayState.RELAY_ON: (1, 'on')>
device.write_gpio_state(gpio_index=0, new_state=1) # Setting (high) GPIO index 0
device.write_gpio_state(gpio_index=1, new_state=0) # Clearing (low) GPIO index 1
device.get_gpio_state(gpio_index=1)
<GPIOState.GPIO_LOW: (0, 'clear')>
device.read_adc(gpio_index=0)
