AdaFruit RGB PushButton Controller

node based controller for AdaFruit rugged metal rgb momentary pushbutton(https://www.adafruit.com/product/3350) (push button not implimented yet)

built on top of pigpio;

index exports = { setup, pinRegistration, cleanUp, colors, defaultPinRegistrations, defaultPWMPinRegistrations, getState:state.getState, setState:state.setState, }

setup and pinRegistration, defaultRegistrations

setup currenty takes in object of

{
    colorPins:[
        {
            color (one of pinRegistration.colors),
            pin (gpio pin number, not physical number),
            pwm (bool)
        },...otherPins
    ]
}

a pin registrations can be made using the pinRegistration function like

const pins = [
    pinRegistration(pinRegistration.colors.red, 18, shouldBePWMBool),
    pinRegistration(pinRegistration.colors.blue, 27),
    pinRegistration(pinRegistration.colors.green, 22)
 ]

the default registrations is

const defaultPinRegistrations = [
    pinRegistration(pinColors.red, 17),
    pinRegistration(pinColors.blue, 27),
    pinRegistration(pinColors.green, 22)
];

also exported is a default pwm registration

const defaultPWMPinRegistrations = [
    pinRegistration(pinColors.red, 18, true),
    pinRegistration(pinColors.blue, 27),
    pinRegistration(pinColors.green, 22)
];

cleanup

this function will just set voltage to 0 on all used pins. The pigpio is supposed to automatically handle terminating everything else.

setState, getState, colors

getState() returns the current state.

setState({colors:{r:num,g:num,b:num}}) will change the color state of the button. if PWM the number should be between 0-255. For non PWM any number other than 0 is interpreted as a 1;

colors is a hash of preset colors, can be called like setState(colors.red);

example

const controller = require("adafruitrgbbuttoncontroller")

setup({colorPins:controller.defaultPWMPinRegistrations});
let r = 0
const i = setInterval(()=>{
    r = r + 10;
    r = r % 255;
    controller.setState({
        color: {
            r,
            g: 1,
            b: 0
        }
    })
},50)
intervals["debug"] = i;

setTimeout(()=>{
    controller.cleanUp();
},10000)
