3.2 MSP430FR2355 Interface Firmware

The MCF8315PWPEVM includes a USB-to-UART-to-I2C interface, using an MSP430FR2355 microcontroller, that serves as a communication bridge between a host PC and the MCF8315 device for configuring various device settings and reading fault diagnostic information.

By default, the onboard MSP430 microcontroller already contains the MSP430FR2355 Motor Studio firmware needed to communicate with the Motor Studio GUI. If there is a firmware update or the GUI does not connect to the EVM, then the user must flash the firmware code into the MSP430 by following the steps outlined in Section 3.2.2.

Flashing the firmware code onto the MSP430 requires an integrated development environment (IDE) and an eZ-FET Debug Probe. The following example uses the Code Composer Studio™(CCS) IDE and the MSP-EXP430FR2355 LaunchPad™ Development Kit to provide the eZ-FET Debug Probe.
