2.11 UNI-3 Interface
Motor control signals from a family of motor driver boards can be connected to the EVM
board via the UNI-3 connector/interface. The UNI-3 connector/interface contains all of
the signals needed to drive and control the motor drive boards. These signals are
connected to differing groups of the DSP’s input and output ports: A/D, TIMER and
PWM. Refer to
for the pin out of the UNI-3 connector.
