6 Summary

This application note has fully defined a BLDC motor hall effect sensor trap implementation using the SimpleLink CC2340R5 and DRV8329A. A description of the necessary hardware connections and MCU programming instructions have been provided so that users are empowered to operate the out-of-box demonstration. Test results have been provided to confirm the stability and robustness of the implementation. The source code is freely accessible and the code flow has been detailed so that developers are familiar with how the project works and are enabled to further modify the project to fit unique application requirements. Readers are encouraged to post to the E2E forum concerning any additional questions Texas Instruments, or support needs that pertain to these resources provided.
