Kaluma library for joystick module.

Here is a wiring example for joystick.

npm install https://github.com/niklauslee/joystick

Here is an example code.

const x = 26;  // GP26 (ACD0)
const y = 27;  // GP27 (ACD1)
const sw = 15; // GP15

const {Joystick} = require('joystick');
const joy = new Joystick(x, y, sw);

setInterval(() => {
  let val = joy.read();
  let valX = val[0].toFixed(2);
  let valY = val[1].toFixed(2);
  let valS = val[2];
  console.log(`x:${valX}, y:${valY}, sw:${valS}`);
}, 500);

• x <number> : The pin number which support ADC function and it shall be connected to X (HOR) pin of the joystick.
• y <number> : The pin number which support ADC function and it shall be connected to Y (VER) pin of the joystick.
• sw <number> : The pin number which support GPIO and it shall be connected to SW (SEL) pin of the joystick.

Internally set the SW pin to INPUT_PULLUP mode. If you have an external pull-up resistor for SW pin, then you need to change the mode after the instantiation.

• Return <number[3]>: Number array with the X, Y and SW value. X and Y value range is from 0 to 1.0 (middle is 0.5) and SW value is the 1 (normal) or 0 (pressed).
