    Hi,

    Where do you want to display the prm file? do you have any prm decoder with you. Any way you will also need a file system to read any file from micro SD card.

    I have an application on STM32C-EVAL board to read jpg / bmp files from a micro SD card using free file system EFSL and display on its on-board TFT. Does it help you??

    Regards,

    Rosarium

    Where he also said that it doesn't work!

    Perhaps they can solve that collectively, I'm not that invested.
