TMS320F28377D: GPIO pin configuration error

Green Deng

Part Number: TMS320F28377D

Dear team:

An error occurred when one of my customers replaced the GPIO pins in the routine:

He uses the gridConnectedInverterLCLFltr_F2837x routine, After he changed the configuration pin of the setupRelayGPIO function to GPIO24, GPIO24 failed to output a high level. 

He blocked the main.syscfg file and changed the SENSING_OPTION in the gridconnectedinvlclfltr_settings.h file from 2 to 1. That is, the AD conversion mode of the routine is switched from SDFM to ADC sampling. At this time, GPIO24 fails to output a high level, but in SDFM mode, GPIO24 can output a high level.

Best regards

    Hi Deng,

    If you are trying to modify any of the settings in the settings.h file, I would recommend that you import the nonpowerSUITE version of the project. This would allow full customization of the application. When trying to change relay GPIO pin, did you modify the #define located in the user_settings.h file?

    Regards,
