    TLE9471ESV33XUMA1 Not responding to spi MISO messages

    Hey all,

    Been having issues receiving SPI Messages back from the device. im working in the STM32 & SPC ecosystem and have tried both boards with no success.

    im using a stm32f4, SPI full duplex with a gpio toggling on and off as the csn. from what i see on the datasheet the spi is configured to MODE 1, with the clock being <5Mhz (im at 1.25)
    i have a feeling that my interpritation of their ardiuno code -> hal_library may be wrong

    I''ve attached my logic analyzer files and c program files including the libraries.

    hope to hear from you soon !

    *update: also forgot to mention the board is running in test mode
    ?????
