# ESP32-C3 BSP 说明
|
||||
|
||||
## 简介
|
||||
|
||||
本文档为 乐鑫ESP32-C3 开发板的[ESP32C3](http://luatos.com/t/esp32c3) BSP (板级支持包) 说明。
|
||||
|
||||
主要内容如下：
|
||||
|
||||
- 开发板资源介绍
|
||||
- BSP 快速上手
|
||||
|
||||
通过阅读快速上手章节开发者可以快速地上手该 BSP，将 RT-Thread 运行在开发板上。
|
||||
|
||||
## 开发板介绍
|
||||
|
||||
目前测试了两款开发板，运行都正常，由于两款开发板LED小灯引脚不同，请根据自己开发板修改GPIO引脚，目前默认使用的开发板是LUATOS_ESP32C3。已测开发板外观如下图所示：
|
||||
|
||||
- [LUATOS_ESP32C3](https://wiki.luatos.com/chips/esp32c3/board.html)
|
||||
|
||||
|
||||
|
||||
- [HX-DK-商](https://docs.wireless-tech.cn/doc/7/)
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
该LUATOS_ESP32C3开发板常用 **板载资源** 如下：
|
||||
|
||||
- MCU：[esp32-c3](https://www.espressif.com/sites/default/files/documentation/esp32-c3_datasheet_en.pdf)，主频 160MHz， 407.22 CoreMark; 2.55 CoreMark/MHz
|
||||
- 芯片内置：384KB ROM, 400KB SRAM,
|
||||
- 常用外设
|
||||
- 红色LED：2个，D4 (IO12), D5（IO13）
|
||||
- 按键：2个，K1（BOOT） K2(RST)
|
||||
- SPI FLASH: 2M
|
||||
- 常用接口：USB UART等
|
||||
|
||||
开发板更多详细信息请参考 [ESP32-C3开发板介绍](https://wiki.luatos.com/chips/esp32c3/board.html)。
|
||||
|
||||
## 外设支持
|
||||
|
||||
本 BSP 目前对外设的支持情况如下：

||||

||||

|
||||
|
||||
## 使用说明
|
||||
|
||||
### 快速上手
|
||||
|
||||
说先要搭建IDE开发环境，乐鑫官方推荐使用IDF开发。
|
||||
|
||||
IDF的搭建方法有很多种，尝试了很多种方法之后，总结了一个最快速的方法，并且可以使用vscode跨平台安装，非常简单方便，具体方法见链接[ESP-IDF 一键式搭建环境基于VSCODE](https://blog.csdn.net/lt6210925/article/details/123699249)。 安装的时候IDF版本请选择IDF 4.4版本。如果你对官方IDF命令行的方式熟悉的话，你也可以使用命令行的方式，这边已经测试过，是可以使用的。
|
||||
|
||||
### IDF patch加载
|
||||
|
||||
由于IDF使用的是FREERTOS需要修改一些文件，将`0001-add-fixed-of-rtthread.patch` 这个文件拷贝到安装的时候的IDF的代码目录，执行命令 `git apply 0001-add-fixed-of-rtthread.patch` 打上patch
|
||||
|
||||
#### 编译下载
|
||||
|
||||
编译选择最下面的按钮：
|
||||
|
||||
|
||||
|
||||
这边通常采用串口下载，需要根据你自己开发板选择对应的串口（如果有JTAG的，也可以用JTAG下载和调试）
|
||||
|
||||
|
||||
|
||||
#### 运行结果
|
||||
|
||||
下载程序成功之后，系统会运行，红色的 D4以 1S 周期闪烁。
|
||||
刚接触ESP32, 目前仅实现LED小灯闪烁，可以print打印，后续计划将pin设备和console对接上去，也欢迎大家一起来贡献，感兴趣的可以通过公众号`Thomas的小火车`来联系
|
||||
|
||||
## 注意事项
|
||||
|
||||
- 目前RTTHREAD支持起来了，后续会需要继续完善一些其他功能，刚开始使用ESP32，欢迎小伙伴一起来讨论和贡献。
