0，安装 ESP32-C3 离线版本:
链接：https://pan.baidu.com/s/1bH6LZhFsVJ2r0f5nues38A
提取码：pdtl
1， 进入编译环境
点击：
.\export.ps1 #环境变了设置，点击PowerShell默认执行了。
2， 编译 【进入到helloworld项目目录】
idf.py build
3, 设置编译环境
idf.py set-target esp32c3
4，下载 【先按Boot再按RST，最后再松开Boot】
idf.py -p com5 -b 115200 flash
5, 监视输出：
idf.py -p com5 monitor
VSCode开发步骤
1, 下载VSCode
2，安装IDF插件
3，编译-下载-监视
开发板：ESP32-C3
4, 测试HelloWorld
ESP32C3程序准备
点灯程序
由于代码的运行需要环境，因此将下载的代码放置在如下图所示位置：
代码：kits_esp32c3: 源码适用于ESP32 C3物联网开发板，同B站“ESP32-C3 RTOS V4.3 SDK从0到1快速上手”系列视频课程同步。 (gitee.com)

非易失性存储 【存储WIFI相关信息】
API文档：非易失性存储库 - ESP32-C3 - — ESP-IDF 编程指南 release-v4.3 文档 (espressif.com)
非易失性存储 (NVS) 库主要用于在 flash 中存储键值格式的数据。
更改项目名称注意事项：
1，example_test.py
2, CMakeList.txt
3，添加头文件：
#include "nvs_flash.h"
#include "nvs.h"
4, NVS基本操作
// Initialize NVS
esp_err_t err = nvs_flash_init();
if (err == ESP_ERR_NVS_NO_FREE_PAGES || err == ESP_ERR_NVS_NEW_VERSION_FOUND) {
// NVS partition was truncated and needs to be erased
// Retry nvs_flash_init
ESP_ERROR_CHECK(nvs_flash_erase());
err = nvs_flash_init();
}
ESP_ERROR_CHECK( err );
// open namespace
err = nvs_open("wifi_config", NVS_READWRITE, &my_handle);
if (ESP_OK != err)
{
printf("open nvs namespace(wifi_config) error\r\n");
}else
{
err = nvs_get_str(my_handle, "ssid", data_out, &data_len );
switch (err) {
case ESP_OK:
printf("Done\n");
printf("########### get ssid success(%d) %s\r\n", data_len, data_out);
break;
case ESP_ERR_NVS_NOT_FOUND:
printf("The value is not initialized yet!\n");
break;
default :
printf("Error (%s) reading!\n", esp_err_to_name(err));
}
}
// write/read nvs_flash
err = nvs_set_str(my_handle, "ssid", "brown123456");
if (err == ESP_OK)
{
printf("write nvs_value success\r\n");
}
err = nvs_commit(my_handle);
if (err != ESP_OK)
{
printf("nvs commit error\r\n");
}
// close namespace
nvs_close(my_handle);
