Native C libraries to GPIO pins?
I just got my Up Board and have it set up and running. I want to transition a project I have been working on with the RPi 3 to the Up Board. The project is driving a large series of 32X32 RGB LED panels. In order to do this I have to trigger the GPIO pins extremely quickly to keep the display updated at 24 bpp color.
I see that some Python libraries have been ported and that is great. However, is there a native C library I can use and documentation to go with it?
