name type required default description
vcc number(obniz Board io) no   Power Supply
gnd number(obniz Board io) no   Power Supply
scl number(obniz Board io) no   scl of I2C
sda number(obniz Board io) no   sda of I2C
i2c object no   obniz i2c object

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);
}
