I'm somewhat stuck with a prob: I have a measuring-transducer Profibus-DP Master-device here that reads probe-values (eg. temperature) and I need to get those values into a Pi or Arduino. The Device is able to do Profibus-DP, PA and Hart.
I am right that there is no finished library and hardware for that? I've found industrial grade ICs like this and opensource stuff that quickly got lawsuited and a shield for RS-485. But even that shield wouldn't help me to actually communicate, right? I still would need to figure out all the protocoll-basics, timing and stuff?
