ESP32

ESP32-CAM

在ubuntu16.04。IDF SDK，类似stm32库开发的方式，将freeRTOS、LWIP、tinyUSB、LVGL等开源库移植到esp32上，配有大量的demos，貌似比stm32开发方便很多

ESP32-CAM的一个demo参看 https://aithinker.blog.csdn.net/article/details/108000974

上手点亮开发板,https://blog.csdn.net/zhigedali/article/details/122714045
1. win10商店可以搜 Arduino IDE,或者去官网 https://www.arduino.cc/en/software,下载win10版本的话也是推荐你用商店装（linux版本就是直接下载）
2. 打开 Arduino IDE，文件>首先项> 额外开发板过滤器中输入 https://dl.espressif.com/dl/package_esp32_index.json，
   其中定义了开发版配置和驱动demos、工具（包括gcc和其他开发用得着的工具），都在github上
3. 工具->开发板->开发板管理器, 搜索 ESP32 并点击安装，这就是下载第二步指定的 demos + tools
4. 工具->开发板->ESP32 Arduino -> AI Thinker ESP32-CAM, 选择刚刚安装的开发板
5. 文件->示例->ESP32->Camera, 选择 CamerWebServer,修改(可能需要另存为),然后验证（就是编译） & 上传（就是编译并通过串口下载到chip）
6. 上传（下载）完毕，工具->串口监视器，115200波特率,chip按rst按键可看到ip信息

例子几乎都是一样的,前面esp32的demo可以直接拿来用, 只是 set-target esp32s3
