			/** @defgroup StrainGauge Driver / Strain gauge
			* @brief Driver for a strain gauge.
			*
			* This driver uses an ADC input, ANIN1 or ANIN2 (see ADC).
			* To use this, connect wire the sensor as this:
			* * sensor + -> +5V (pin 1 or 5 of J2).
			* * sensor - -> GND (pin 2 or 6 of J2).
			* * sensor sense -> ANINX+ (pin 3 or 7 of J2).
			* * 2.5V (with a voltage divider between 5V and GND) -> ANINX- (pin 4 or 8 of
			* J2).
			*
			* Set the sensitivity switches to +-33mV.
			*
			* Call sg_Init() first in the initialization code. Then, call sg_Get() to
			* get the force.
