2.1 Quick Start Guide

The MCF8315RRYEVM requires a power supply source, which has a recommended operating range from a 4.5V to 35V. To setup and power the EVM, follow the sequence below:

  1. Connect motor phases to A, B, C on connector J8.
  2. Do not turn on the power supply yet. Connect motor supply to VBAT/VM and PGND on connector J7.
    1. To enable reverse polarity protection and Pi filter, connect to VBAT. Note that when connecting to VBAT, VM is VM – 0.7V less, due to a diode drop in the reverse-polarity protection circuit.
    2. To disable reverse-polarity protection and the Pi filter, connect to VM.
  3. Set J3 to 5V_USB and J5 to 3V3COM to power MSP430™ from USB power supply.
  4. Connect the micro-USB cable to the computer.
  5. Turn the potentiometer fully clockwise to set the motor to zero speed upon powerup.
  6. Flip the switch S1 to the right to configure BRAKE = RUN, switch S2 to the left to configure DIR = ABC, and switch S3 to the right to configure DRVOFF = ON
  7. Set J1 to POT to apply the analog voltage from potentiometer R4 to the SPEED pin.
  8. Turn on the motor power supply.
  9. Use the potentiometer R4 to control the speed of the motor and the switches to disable the motor driver, change the direction, or apply a brake to the motor. Optionally, use the GUI (as shown in Section 3) to monitor real-time speed of the motor, put the MCF8315 into a low-power sleep mode, and read status of the LEDs.
