pymonome

pymonome is a pure Python library for easy interaction with the monome family <https://monome.org> of devices. It supports grid and arc controllers (via serialosc) and provides additional facilities for developing grid- and arc-based applications.

Installation

pymonome requires at least Python 3.6. It can be installed using pip:

pip3 install pymonome

Or use the --user option to install pymonome to the current user library directory:

pip3 install --user pymonome

Usage

pymonome does not communicate with any of the devices directly. Like many monome applications, it relies on serialosc for device detection and hardware input and output. As serialosc provides OSC (UDP) ports for all the devices connected to the host system, it is possible to connect to a grid via a known UDP port as follows:

import monome

GRID_HOST = '127.0.0.1'
GRID_PORT = 16816

grid = monome.Grid()
await grid.connect(GRID_HOST, GRID_PORT)
grid.led_set(0, 0, 1)

Alternatively, it is possible to instantiate the protocol class using the loop.create_datagram_endpoint() event loop method:

transport, grid = await loop.create_datagram_endpoint(monome.Grid,
    remote_addr=(GRID_HOST, GRID_PORT))

In practice, however, UDP ports will be randomly assigned to devices as they are connected to the host computer. serialosc has a discovery and notification mechanism to notify clients about connected devices, so we can use this in pymonome as follows:

import asyncio
import monome

class HelloApp(monome.GridApp):
    def on_grid_key(self, x, y, s):
        self.grid.led_set(x, y, s)

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    hello_app = HelloApp()

    def serialosc_device_added(id, type, port):
        print('connecting to {} ({})'.format(id, type))
        asyncio.ensure_future(hello_app.grid.connect('127.0.0.1', port))

    serialosc = monome.SerialOsc()
    serialosc.device_added_event.add_handler(serialosc_device_added)

    loop.run_until_complete(serialosc.connect())

    loop.run_forever()

In the example above, application instance (HelloApp) will be connected to the latest grid discovered and pressing the button will light the corresponding LED. For more examples see the examples/ directory.
