			* @brief Driver for a tachometer.
			*
			* This driver uses an ADC input, ANIN1 or ANIN2 (see ADC).
			* To use this, connect wire the sensor as this:
			* * tacho 1 -> ANINX+ (pin 3 or 7 of J2).
			* * tacho 2 -> ANINX- (pin 4 or 8 of J2).
			*
			* Set the sensitivity switches to +-2V.
			*
			* Call tac_Init() first in the initialization code. Then, call tac_Get() to
			* get the motor speed.
