Interfacing Drv8323Rx And Msp430F5529 Launchpad - Texas Instruments BOOSTXL-DRV8323Rx User Manual

Hardware and Software Overview
LED1 and LED2 — During normal motor operations LED1 and LED2 define the direction of spin. When
any fault occurs. LED1 and LED2 flashes in different patterns to identify the fault.

Interfacing DRV8323Rx and MSP430F5529 LaunchPad

The DRV8323Rx device has 40 pins with different functions. These pins are interfaced with the
MSP430F5529XL LaunchPad development kit which is mapped appropriately to receive the functionality
of the BoosterPack plug-in module. These 40 pins are grouped into 4 ports.
