ESP32

ESP32-CAM

stay ubuntu16.04.IDF SDK, similar stm32 The way of library development , take freeRTOS、LWIP、tinyUSB、LVGL Wait for the open source library to migrate to esp32 On , Equipped with a large number of demos, Resemblance ratio stm32 Development is much more convenient

IDF For development environment, please refer to https://aithinker.blog.csdn.net/article/details/121565113

ESP32-CAM One of the demo see https://aithinker.blog.csdn.net/article/details/108000974

Start lighting up the development board ,https://blog.csdn.net/zhigedali/article/details/122714045
1. win10 Shops can search Arduino IDE, Or go to the official website https://www.arduino.cc/en/software, download win10 It is also recommended that you install it in the store （linux Version is to download directly ）
2. open Arduino IDE, file > First item > Input in the filter of the additional development board https://dl.espressif.com/dl/package_esp32_index.json,
    It defines the development version configuration and driver demos、 Tools （ Include gcc And other development tools ）, All in github On
3. Tools -> Development board -> Development board Manager , Search for ESP32 And click Install , This is what is specified in the second step of downloading demos + tools
4. Tools -> Development board ->ESP32 Arduino -> AI Thinker ESP32-CAM, Select the development board you just installed
5. file -> Example ->ESP32->Camera, choice CamerWebServer, modify ( You may need to save as ), And then verify （ It's compiling ） & Upload （ It is to compile and download to chip）
6. Upload （ download ） complete , Tools -> Serial monitor ,115200 Baud rate ,chip Press rst Press the key to see ip Information
