let me show what we did: we use the CCI ISOBUS Stack, written in C, https://github.com/Meisterschulen-am-Ostbahnhof-Munchen/Install-ISOBUS-Environment/wiki ISOBUS makes GUI Communication ECU <--> Display over CAN, and much more for Smart Agriculture, which seems to be one of the Focus Topics of M5. i am a Teacher at School, and i want to Teach it in UIFlow instead of C, because easier to learn.
