Maxim Integrated / Mbed 2 deprecated MAXREFDES89_Test_Program

Functional test program for MAXREFDES89# that ramps each motor driver output up/down and in each direction sequentially. Uses default configuration, i.e. pwm signals are on D4, D5, D9 and D10 along with default I2C addresses for supporting I.C.s.

Dependencies:   MAX14871_Shield mbed
