Nanopb Protocol Buffers Generator

Nanopb is a small code-size Protocol Buffers implementation in ANSI C, primarily suitable for microcontrollers and other memory-restricted systems. The Python library component provides the `nanopb_generator.py` script, which compiles `.proto` definition files into C header (`.h`) and source (`.c`) files that can then be used with the Nanopb C runtime. The project is actively maintained, with versions typically released a few times a year, addressing bug fixes and minor improvements, such as the latest 0.4.9.1 release from December 2024.
