Command-line interface for Numato relay module

This is a python implementation of a command-line interface to Numato two-channel USB relay module.

First-time setup on a new machine

MacOS / Linux

$ python3 -m venv venv
$ source venv/bin/activate
$ pip install --upgrade pip
$ pip install -r requirements.txt

Windows

PS> python3 -m venv venv
PS> venv\Scripts\activate.bat & ^
    pip install -r requirements.txt

Run directly

$ source venv/bin/activate
$ python relay-control.py

usage: relay-control.py [-h] [-v] [-r] [-s {off/off,on/off,off/on,on/on}]

Interface to a Numato two-channel USB relay module

optional arguments:
  -h, --help            show this help message and exit
  -v, --verbose         Verbose output (repeat to increase)
  -r, --read            Read state of relays
  -s {off/off,on/off,off/on,on/on}, --set-state {off/off,on/off,off/on,on/on}

"on/off" means relay 0 on and relay 1 off, etc.

Compile stand-alone executable

MacOS / Linux

$ pip install -r requirements-dev.txt
$ build-app.sh

Windows

PS> pip install -r requirements-dev.txt
PS> build-app.bat
