Probably you need an internet connection to your PSoC board first before looking for protocols. Make a keyword search (at top of this page) for keywords like "LAN", "Ethernet" or "TCP"
Actually networking is not needed. Protocol bufers are just a serialization mechanism, and are independent from the transport mechanism. So they can be used for serial ports or CAN (the tutorials work with binary files instead). (See the overview)
You probably also don't want to use the standard protobuf compiler, since it generated C++ code. Instead I suggest using the protobuf-embedded-c project
As hli stated, I already have the transport mechanism handled, I simply need an embedded version of the protobuffer that can serialize my data and to be able to set up the Python version to interpret the data on the other end.
I will look into this embedded protoc.
hli, I don't see how I would go about setting up the embeded systems protobuffer on the psoc board. Is there a way to include this functionality through PSoC creator that I dont know about?
You would need to run the protoc compiler externally. When it has finished creating the code, just copy it into your project, just like code you have written manually. (And when you do some changes to the protocol definiton you need to do it tagain)
There is no facility in Creator to handle this automatically.
