+# protobuf-c
+
+## 1、介绍
+
+Google 的 prototol buffer 一种轻便高效的数据存储格式，可以很方便地把结构化的数据用二进制的格式保存起来，很适合高效地数据存储和传输。
+
+## 2、项目说明
+
+| 名称     | 说明       |
+| -------- | ---------- |
+| doc     | 文档目录   |
+| examples | 例子目录   |
+| src      | 源代码目录 |
+
+## 3、如何使用 protobuf-c
+
+使用 protobuf-c 需要在 RT-Thread 的包管理器中选择它，具体路径如下：
+
+```
+RT-Thread online packages
+  IoT - internet of things  --->
+      [*] protobuf-c: a C implementation of the Google Protocol Buffers data serialization format on RT-Thread
+```
+
+然后让 RT-Thread 的包管理器自动更新，或者使用 `pkgs --update` 命令更新包到 BSP 中。
+
+## 4、注意事项
+
+- 如果使用了 encode_decode_file 例程，需要打开文件系统支持
+
+## 5、感谢
+
+- protobuf-c: [https://github.com/protobuf-c/protobuf-c](https://github.com/protobuf-c/protobuf-c)
