I would like to set up google's protocol buffers on my PSoC board so I can send the compressed data to a python script for interpreation. I was curious if anyone else has already done this or something similar. Any help or suggestions are welcome. Let me know if there is more specific information you want.
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.
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.
