Nanopb
|

======
|
|
|
|
The ``$dir_pw_third_party/nanopb/`` module contains Nanopb, a tiny protobuf
|
|
library. It is used by :ref:`module-pw_protobuf_compiler`.
|
|
|

----------------

GN Build Support
|
|
----------------
|
|
This module provides support to compile Nanopb with GN.
|
|
|
|
Follow the documentation on :ref:`module-pw_protobuf_compiler` for general
|
|
help on how to use this.

|
Enabling ``PB_NO_ERRMSG=1``
|
|
---------------------------
|
|
|
|
In your toolchain configuration, you can use the following:
|
|
|
|
.. code-block::
|
|
|
|
pw_third_party_nanopb_CONFIG = "$dir_pw_third_party/nanopb:disable_error_messages"
|
|
|
|
|
|
This will add ``-DPB_NO_ERRMSG=1`` to the build, which disables error messages
|
|
as strings and may save some code space at the expense of ease of debugging.
