// The MotorDriver definition is:
//
// MotorDriver(byte power_pin, byte signal_pin, byte signal_pin2, int8_t brake_pin, byte current_pin,
// float senseFactor, unsigned int tripMilliamps, byte faultPin);
//
// power_pin: Turns the board on/off. Often called ENABLE or PWM on the shield
// signal_pin: Where the DCC signal goes in. Often called DIR on the shield
// signal_pin2: Inverse of signal_pin. A few shields need this as well, can be replace by hardware inverter
// brake_pin: When tuned on, brake is set - output shortened (*)
// current_pin: Current sense voltage pin from shield to ADC
// senseFactor: Relation between volts on current_pin and actual output current
// tripMilliamps: Short circuit trip limit in milliampere, max 32767 (32.767A)
// faultPin: Some shields have a pin to to report a fault condition to the uCPU. High when fault occurs
//
// (*) If the brake_pin is negative that means the sense
// of the brake pin on the motor bridge is inverted
// (HIGH == release brake)
