Hi folks, this became an interesting thread and Manivannan made some nice changes to MRAA as a result. It appears the Raspberry Pi has become a victim of its own success and went from hobbyist toy system to a foundation for random industrial control hacks. I'm a bit scared about that for electronic reasons but when it comes to the software that is a board that get things right after we added line-names to everything on its connectors. What I can add is that when designing the character device I tried to get some input from inductrial control (PLC) vendors and asked on the mailing list, and mailed directly to ABB at one point, I am sorry for not finding the right contact at Siemens (would have helped for sure). I have tried to talk to Liebherr in related matters but can't seem to find the right contact. We really want to do things right with industrial control boards because these seem to have very long life cycles and stay around forever in the kernel for that reason. Yours, Linus Walleij
