The Bolt manual talks about the Embedded Controller (not Arduino) making additional GPIOs available, but I couldn't see any details anywhere on how to actually set up, access and use these? Is there any further details / documentation / examples for the embedded controller, and how to utilize it anywhere? Thanks
I found the documentation in the end, it is here for anyone looking. https://www.udoo.org/docs-bolt/BIOS_UEFI_and_Tools/EAPI.html
