Joseph Bradshaw / Mbed 2 deprecated mbed_SY202_MotorTest

Program for testing the motor with SY202 connection from the application board to the L298 motor driver board.

Dependencies:   MotCon mbed

SY202 Motor Test Program

This program exercises a DC motor driver using pins 23, 24, and 25 as (PWM, DIR1, DIR2 respectively) motor control signals on the mbed application board. These pins are also tied to the on-board RGB LED.
