    I wrote a script that opens and reads a pipe, however, I cannot seem to find the image pipes for the cameras. I am new to FIFO pipes, can someone help me where I can find the image pipe for the hires camera on VOXL2?

      @martongonczy https://docs.modalai.com/mpa-camera-interface/

      All MPA pipes live in /run/mpa, e.g. /run/mpa/hires

        @tom thank you for your help.

        I can only see these pipes in that directory. I managed to retrieve data from voxl-tflite-server0, however that is for the tflite-server and I cannot find the pipe for the hires camera without the tflite overlay.
        Could it be that I forgot to start a service?

          @martongonczy You'll need to use an MPA based client in order to read from the pipe, like in voxl-inspect-cam : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/master/tools/voxl-inspect-cam.c?ref_type=heads

          what you're seeing is voxl-tflite-server reading from the hires pipe
