Grove_JoyStick

X and Y direction with Push Switch Joystick.
It uses the I2C communication.

wired(obniz, {[scl, sda, vcc, gnd, grove]})

connect to the obniz device.
White, yellow, red and black wires correspond to scl, sda, vcc and gnd respectively.

var joystick = obniz.wired("Grove_JoyStick", { scl:0, sda:1, vcc:2, gnd:3 });

If the device has a grove interface, it can be connected with just the parameter {grove: obniz.grove0}.

var obniz = new Obniz.M5StickC("OBNIZ_ID_HERE");
obniz.onconnect = async function() {
  var joystick = obniz.wired("Grove_JoyStick", { grove: obniz.grove0 });
}

[await] isPressedWait()

get the button state once.

// JavaScript Examples
var joystick = obniz.wired("Grove_JoyStick", { grove: obniz.grove0 });
var isPressed = await joystick.isPressedWait();
if (isPressed) {
    console.log("Pressed!");
}

[await] getXWait()

[await] getYWait()

get X or Y angle once.

Value range is 0 to 255. Device has individual difference. So minimum and maximum value is different on each joystick.

// JavaScript Examples
var joystick = obniz.wired("Grove_JoyStick", { grove: obniz.grove0 });
while(true) {
  var x = await joystick.getXWait()
  var y = await joystick.getYWait()
  console.log(`${x}-${y}`);
  await obniz.wait(1);
}
