Detailed Description

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.
