	/** @defgroup Hall Driver / Hall sensor
	* @brief Driver for a Hall-effect angular sensor.
	*
	* This driver uses an ADC input, ANIN1 or ANIN2 (see ADC).
	* To use this, connect wire the sensor as this:
	* * hall red -> +5V (pin 1 or 5 of J2).
	* * hall yellow -> GND (pin 2 or 6 of J2).
	* * hall blue -> ANINX+ (pin 3 or 7 of J2).
	* * GND (pin 2 or 6 of J2) -> ANINX- (pin 4 or 8 of J2).
	*
	* Set the sensitivity switches to +-10V.
	*
	* Call hall_Init() first in the initialization code. Then, call hall_Get() to
	* get the angle of the paddle.
	*
	* @addtogroup Hall
