Alternative boards – RockiPi 4c plus

[sb995]

Hi! First of all thank you for this superlative work!
I want to try OSPi but i have a RockPi 4c plus running Frigate NVR that I want to use. This is a good SBC with soldered eMMC module that I consider a big plus.
Has anyone tried to use the HAT in this board? As I know, the GPIO layout seems compatible. For reference, here you can see the GPIO layout of the Rock4

I noticed that the the comparison that i made is taken from the mapping assignment in WiringX library, so they are the same only if using this library i think, what interfacing library is used by OSPi firmware?

The ‘interfacing’ functions are in the gpio.cpp file:
https://github.com/OpenSprinkler/OpenSprinkler-Firmware/blob/master/gpio.cpp#L185
it uses direct read/write of system files. It’s also possible to use command line tools, like the ‘raspi-gpio’ command to implement most of these functions.
