.. _nanopb_sample: Nanopb sample ############# Overview ******** A simple protocol buffer sample using :ref:`nanopb_reference` for serializing structured data to platform independent raw buffers or streams. The structured data to encode/decode is presented as follows: .. code-block:: proto syntax = "proto3"; message SimpleMessage { int32 lucky_number = 1; bytes buffer = 2; int32 unlucky_number = 3; } Configuration ************* This sample uses two configuration options to modify the behavior. * :kconfig:option:`CONFIG_SAMPLE_BUFFER_SIZE` sets the ``buffer`` field's size * :kconfig:option:`CONFIG_SAMPLE_UNLUCKY_NUMBER` either enables or disables the ``unlucky_number`` field. Building and Running ******************** This application can be built as follows: .. zephyr-app-commands:: :zephyr-app: samples/modules/nanopb :host-os: unix :board: qemu_x86 :goals: run :compact:
