- Hardware pull-ups are not required for switch.
-- Attach a joystick connected as
-- x external ADC (ADC1115) / channel 0
-- y external ADC (ADC1115) / channel 1
-- sw (switch) GPIO26
s = sensor.attach("ANALOG_JOYSTICK", adc.ADS1115, 0, adc.ADS1115, 1, pio.GPIO26)
-- Register a callback. Callback is executed when some sensor property changes.
