[protobuf] Evaluation of Protobuf C++ in embedded environment

2014-11-11 Thread Tamás Somhegyi
Hello,

I design a measurement device (CAN and LIN bus monitoring unit) and I use a 
microcontroller (1MB flash, 256k RAM, 66MHz).
Is it possible to use the c++ implementation in a limited device like this 
(lite version)?
If it is possible then which files are necessary for the runtime 
environment?
As it seems to me the compiler and runtime files are next to each other so 
it is a little hard to me to determine which files should I add to my build.

I am evaluating a third-party library called nanopb but I would like to use 
the official version if it is possible.
Are there any c++ std library dependency which might not be available in an 
embedded device?

Best Regards,
Tamas Somhegyi

[protobuf] Message encoding question

2014-10-15 Thread Tamás Somhegyi
Hello,

I am quite new to Protocol Buffers but I have read the tutorials. There is 
one part of the encoding which I don't understand.
How the message types are encoded? As I see the tutorial mentions the field 
encoding but the field id is unique only in the message.

Best regards,
Tamas
