5 Hardware Setup

The hardware required to run the motor is the MCT8317EVM, a Micro-USB cable, and a power supply with a DC output from 4.5-V to 20-V. Follow these steps to start up the MCT8317EVM:

  1. Connect the DC power supply to header J7. Connect to VBAT and PGND to apply reverse polarity protection and the pi filter to the EVM. Otherwise, connect to VM and PGND to bypass the reverse polarity protection and pi filter.
  2. Apply user configurable jumper settings. See Section 4.5 section for more information.
  3. Flash program into the MCU as described in Section 4. Launch the GUI in GUI Composer and disconnect the 4-pin JTAG connections.
  4. Connect a Micro-USB cable to the MCT8317EVM and computer.
  5. Turn on the power supply and power up the PCB.

If using the MCT8317EVMj with an external microcontroller, remove all shunt jumpers from jumper bridge J6. Connect with external jumpers to the left side of the jumper bridge from the external MCU.
