I was wondering if anyone could clarify something for me.
I am curious about what protocol(s) which are actually used for the hardware interfacing of OpenModelica and Arduino board presented in the book "Microcontroller Programming with Arduino and OpenModelica". I have seen mentioning of the RS-232 protocol but am uncertain if this is defined in the various toolboxes in the source-code, or if this is something that is defined in the shield.
If one would want to connect an Arduino board directly to a computer, then communicate via OpenModelica, is the Modbus Protocol (described in Chapter 11) the way to go?
I greatly appreciate it if anyone would clarify these issues for me.
