    Hello Georg,

    Thanks for the question.

    Can you confirm if you are looking to use the MCU in the EVM itself? Or there is any other hardware that you are trying to interface.

    Thanks,

    Ibinu

    Hello Ibinu,

    yes, I like to use the MCU in the EVM as is. But instead of using the DRV884x-EVM-GUI I like to give commands to the MCU by my own script. Idea behind that is to operate the EVM automated, not manually.

    Best regards
    Georg

    Hello Georg,

    Unfortunately we have not tried the communication with python drivers. But the basic principle should work.  The GUI uses UART communication to talk to the MCU. The EVM FW has the implementation of the same (which can be downloaded from the EVM page).

    An alternate approach would be to use any hardware which you can control through python and provide the required digital signals can be wired onto the jumpers on board to control the device.

    Thanks,

    Ibinu
