pymonome 0.11

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

Basic 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))

Service discovery API

In practice 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. It’s possible to connect to the discovery service from pymonome too:

grid = monome.Grid()

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

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

await serialosc.connect()

Application classes

For extra convenience pymonome provides base classes for developing grid and arc-based apps, apps on grid sections, or pages on the same grid. Application base classes provide handler stubs for input events and member properties for accessing controllers.

import asyncio
import monome

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

async def main():
    loop = asyncio.get_running_loop()
    hello_app = HelloApp()

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

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

    await serialosc.connect()
    await loop.create_future() # run forever

if __name__ == '__main__':
    asyncio.run(main())

In this example, HelloApp application instance will be connected to the latest discovered grid and pressing a button will light the corresponding LED.
