/** @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.
*
