Hi all,
Firstly thanks for all the comments and insights, very useful and maybe I needed to look at this from a different perspective and rephrase my question!
I can see the point about the MOD bus being unnecessary for a home application like mine, I am also driven by the idea that I wanted to learn more about the protocol as well. However it sounds like I am better using an easier protocol for the home system and will look at protocols better supported by the Tiva C in this case.
Now as I said I have an interest in trying to learn a bit more about MOD bus, is there a particular microcontroller that someone can recommend that would be a good hardware platform for this purpose? (I would say the MSP430G series devices are not suitable for example, as the USI and USCI on these devices means poor internal peripheral hardware support).
Thanks again,
Suze
