projector-controller

projector-controller is a node.js NPM package that allows generic controller over display projectors that have an RS-223 serial interface and an API scheme.

Example (using default COM port)

var controller = require("projector-controller");

controller.config({
    name: "NEC",
    baudRate: 38400,
    on: [0x02, 0x00, 0x00, 0x00, 0x00, 0x02],
    off: [0x02, 0x01, 0x00, 0x00, 0x00, 0x03],
}, () => {
    controller.on((success) => {
        return;
    });
});

Setting specific port

If you have multiple COM ports defined, you can specify which port yourself in code.

var controller = require("projector-controller");

controller.config({
    name: "NEC",
    baudRate: 38400,
    on: [0x02, 0x00, 0x00, 0x00, 0x00, 0x02],
    off: [0x02, 0x01, 0x00, 0x00, 0x00, 0x03],
    settings: [0x00, 0x85, 0x00, 0x00, 0x01, 0x00, 0x86]  // 00h 85h 00h 00h 01h 00h 86h
}, () => {
    controller.setPort("COM3", () => {
        controller.off((success) => {
            return;
        });
    });
});

Summary

Basically, you pass your particular projector's API specifications in JSON format and the projector-controller takes care of all the serial port communication.

I welcome any and all pull requests. I specifically need help with unit testing and code structure (async, callback, promises).
