I'm hoping to use two SPI channels so that I can load images from SD card and push bits to the display concurrently. This seems a good approach to me as little time will be wasted.
I also considered using jpg compression but I suspect the time taken to decode will be longer than time saved.
Does this seem like a good scheme or are the time savings not worthwhile?
Most examples I can find are for ESP32 but I think alterations for STM32 should be do able - not sure about spiffs.
Any advice most welcome.
