DRV8329AEVM: With MSPM0G3507 LaunchPad, I have questions about the pin settings in the guide.

Tool/software:

Hi expert, 

https://dev.ti.com/tirex/explore/content/mspm0_sdk_2_03_00_07/docs/english/middleware/motor_control_pmsm_sensorless_foc/doc_guide/doc_guide-srcs/drv8329/DRV8329_Hardware_User_Guide.html

According to the hardware guide above, pins PA17 and PA24 are supposed to be connected to ISENA on the DRV8329 board, but looking at the pin settings in the software example, it seems more appropriate to connect them to PA18.

In this way, the descriptions in the software examples and hardware setup guides don't seem to match.

Thanks Donguk

    I solved this problem by modifying sysconfig and gateDriver.h and drv8329_focHalInterface.c. I thought I only had to change the motor parameters since it was an example code, but I found out that I had to additionally configure the ADC for current sensing. The problem was completely solved. However, I think I should add the default setting of PA17 and PA24 for ADC sensing in the example code.
