-## Quickly Get Started
+## Quick Start Guide
-
-First of all, we'll need to build the IDE, Espressif officially recommends the IDF. 
-When installing the IDF, please select version 4.4. If you are familiar with the official IDF command line, you can also use the command line to perform the `idf.py build` directly in the `bsp/esp32_c3`, which has been tested and proved that it's functional
-
-### ESP-IDF Adds RT-Thread patch
-
-The IDF was running the FreeRTOS, so we'll need a few modifications to get to RT-Thread. 
-Copy the `rtt.patch` file to the IDF code directory, and then execute the next few commands on the `git bash` command line to mark the patch.
 
+1. Download ESP-IDF package
 ```
-cd esp/esp-idf
+pkgs --update
-git checkout v4.4
-git am rtt.patch
 ```
-
+2. Go to ESP-IDF package directory and install IDF tools. This command only needs to be run once after the package is downloaded for the first time.
-If you don't want to use the patch file and have uploaded the code to GitHub, you can now go to [tangzz98/esp-idf](tangzz98/esp-idf) to download the latest `freertos_wrapper` branch code. After the modification, the original IDF example is still kept in normal use, they won't interfere with each other.
+```
-
+cd packages/ESP-IDF-latest
-#### Compile and Download
+./install.sh
-
+# Use install.bat in Windows environment
-Right-click `bsp/ESP32_C3` and use vscode to open the project
+```
-
+3. Under the ESP-IDF package directory, export IDF environment variables. This commands need to be run every time when the BSP is built in a new terminal.
-Compile and select the button at the bottom:
+```
-
+. export.sh
-![build](images/build.png)
+# Use export.bat in Windows environment
-
+```
-Here we usually use the serial port to download, you need to choose the corresponding serial port according to your own development board (if there is JTAG, you can also use JTAG to download and debug)
+4. Configure RT-Thread under the BSP directory
-
+```
-![](images/burn.png)
+scons --menuconfig
-
+```
-Once the project is successfully downloaded, the system runs automatically, the red LED will blink in 1s on cycles.
+5. Whenever RT-Thread configuration is changed with `scons --menuconfig`, a new `CMakeLists.txt` needs to be generated with the command below
+```
+scons --target=esp-idf
+```
+6. Use `idf.py` to compile and upload the program. Refer to [Espressif official documents](https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/get-started/index.html#build-your-first-project) for reference.
+7. Once the project is successfully downloaded, the system runs automatically, the red LED will blink in 1s on cycles.

 ## 使用说明
 
-### 快速上手
+1. 下载ESP-IDF软件包
-
-先要搭建IDE开发环境，乐鑫官方推荐使用IDF开发，这边建议使用vscode插件。
-
-IDF的搭建方法有很多种，尝试了很多种方法之后，总结了一个比较好用的方法，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，直接在`bsp/esp32_c3`中执行`idf.py build`即可，这边已经测试过，是可以使用的。
-
-### ESP-IDF 添加RT-THREAD patch 
-
-由于IDF使用的是FREERTOS，如果需要使用rt-thread就需要修改一些文件。将`rtt.patch` 这个文件拷贝到IDF的代码目录下面，然后在`git bash`命令行内执行命令下面几条命令就可以打上patch
-
 ```
-cd esp/esp-idf
+pkgs --update
-git checkout v4.4
-git am rtt.patch
 ```
-
+2. 进入到ESP-IDF软件包路径，安装IDf工具链。此命令只需要在下载完软件包后执行一次。
-如果不想用patch文件，已经将代码上传到github上面，可以进入[tangzz98/esp-idf](https://github.com/tangzz98/esp-idf/tree/freertos_wrapper) 下载最新的freertos_wrapper分支代码即可。修改之后的IDF，原来的IDF的example还是正常使用，互不干扰，可以放心使用。
+```
-
+cd packages/ESP-IDF-latest
-#### 编译下载
+./install.sh
-
+# Windows环境下使用install.bat
- 在`bsp/ESP32_C3`中右击，然后使用vscode打开工程
+```
-
+3. 在软件包路径下设置IDF路径。每当在新的命令行编译BSP时需要执行此命令。
-编译选择最下面的按钮即可：
+```
-
+. export.sh
-![build](images/build.png)
+# Windows环境下使用export.bat
-
+```
-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）
+4. 在BSP路径下配置RT-Thread
-
+```
-![burn](images/burn.png)
+scons --menuconfig
-
+```
-#### 运行结果
+5. 每当使用`scons --menuconfig`更改RT-Thread配置后需要重新生成`CMakeLists.txt`。
-
+```
-下载程序成功之后，系统会运行，红色的 LED灯以 1S 周期闪烁。
+scons --target=esp-idf
-感兴趣的可以通过公众号`Thomas的小火车`来联系
+```
+6. 使用`idf.py`命令编译，烧录。具体参考[乐鑫官网](https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/get-started/index.html#build-your-first-project)
+7. 下载程序成功之后，系统会运行，红色的 LED灯以 1S 周期闪烁。
 
 ## 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。
