Simple monome grid library.
Install via NPM:
npm install monome-grid
const monomeGrid = require('monome-grid')('m1000079');
async function run() {
let grid = await monomeGrid();
grid.key((x, y, s) => console.log(`x: ${x}, y: ${y}, s: ${s}`));
setInterval(() => {
let led = [];
for (let y = 0; y < 8; y++) {
led[y] = [];
for (let x = 0; x < 16; x++) {
led[y][x] = Math.floor(Math.random() * 16);
}
}
grid.refresh(led);
}, 100);
}
run();First create a grid object:
const grid = require('monome-grid')('m1000079');You can leave the id (m1000079) empty to bind to the first grid object:
const grid = require('monome-grid')();You can define a key listener that gets called whenever a key press event is received. The x and y arguments represent the coordinates of the button press and the s argument represents the state (1 = pressed, 0 = released):
// prints x: 2, y: 3, s: 1
grid.key((x, y, s) => console.log('x: ' + x + ', y: ' + y + ', s: ' + s));The refresh() method takes a 2-dimensional LED array as an argument. The first dimension is y and the second dimension is x. This will automatically adjust for varibright or non-varibright grids. For example:
// initialize empty led array
let led = [];
// iterate over 8 columns
for (let y = 0; y < 8; y++) {
// initialize second dimension of array (x values)
led[y] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15];
}
grid.refresh(led)You should initialize the LED array to the size of your monome. For example, a 128 should use an 8x16 array.
