JPEG Hardware Encode/Decode support

[metanav]

I am interested in having the ArduinoCore Mbed include support for JPEG hardware encode/decode for STM32H7 based MCUs. I attempted to implement it using the OpenMV code or directly from the STM32CubeH7 examples, but they were unsuccessful with Mbed. With the introduction of the Giga R1 Display shield, direct support of this functionality is necessary to decode 800x480 pixels large images.
