1、安裝arduino

https://www.arduino.cc/en/Main/Software?setlang=cn

2、配置esp32

打開首選項

image.png

配置開發(fā)板

image.png

根據(jù)esp32搜索選中安裝；

image.png

文件比較大下載比較慢，如果有需要請翻墻處理；

image.png

3、配置編譯tools

C:\Program Files (x86)\Arduino\hardware
建立目錄espressif/esp32

image.png

https://github.com/espressif/arduino-esp32
下載文件然后復(fù)制到目錄；

image.png

4、體驗測試；

選擇開發(fā)板類型

image.png

選擇sample程序

image.png

image.png

修改攝像頭類型；改成安信可esp32-cam

// Select camera model
//#define CAMERA_MODEL_WROVER_KIT
//#define CAMERA_MODEL_M5STACK_PSRAM
#define CAMERA_MODEL_AI_THINKER

配置wifi

const char* ssid = "HI-WOOYA_471D";
const char* password = "12345678";

編譯

選擇項目菜單，編譯/驗證試試看；

image.png

運行成功；

燒錄固件；

選擇esp32-cam對應(yīng)的串口；

image.png

選擇菜單上傳；
需要把燒錄的接口接gnd，然后觸發(fā)reset下；然后就看到編譯后開始燒錄了；

image.png

5、測試效果；

arduino的串口調(diào)試不夠方便，推薦友善調(diào)試助手；

把燒錄的 杜邦線拿掉；
reset下；

根據(jù)提示的ip地址訪問下，要連接同一個wifi；
視頻就是連接輸出更多的圖片；圖片越大延時越大；

可以調(diào)節(jié)各種參數(shù)，亮度、白平衡。
esp32-cam竟然還能人臉識別，超厲害；

6、擴展

可以抓圖或者人臉識別傳送后臺服務(wù)器；
比如采用sim800l類似的透傳芯片；
https://github.com/carrascoacd/ArduinoSIM800L
通過at指令發(fā)送數(shù)據(jù)亦可；
https://github.com/erdemarslan/GSMSim
也可以跑mqtt；
https://github.com/martinhol221/SIM800L_MQTT
nb-iot arduino開發(fā)，sim7020芯片
https://github.com/pornpol/NB_Meter_SIM7020E
https://create.arduino.cc/projecthub/voske65/arduino-nb-iot-with-sim7020-and-t-mobile-027f8f

7、批量燒錄方式補充

arduino燒錄后找到臨時目錄，如下類似；

C:\Users\3doyen\AppData\Local\Temp\arduino_build_810217

image.png

復(fù)制紅框文件出來；

下載bootloader
