I’m struggling for some general solution in control GPIO.

We have some daemons running on Pi’s but want to go to the UP for professional reasons.
But as always: how can I read/write/call the GPIO part of this x86 board.
I found MRAA but don’t know how to call such a thing within Xojo.

Who can, who want, make this MRAA kit available for Xojo (building for Linux/x86) an what is your price?

Or do I think in the wrong way and is there an easier way to go?
