2、摘下esp32-cam的跳线帽,使其处于运行调试模式。 3、打开Serial Monitor查看esp32-cam运行情况按下esp32-cam上的rebot按钮。 4、esp32-cam进行ota更新。 Serial.Monitor信息 至此成功实现esp32-cam的ota更新。 5.问题 我在实现这个过程中遇到过不少问题我在文章中写下做个记录。 5.1 问题一:证书

刷完后,打开串口读取一下信息,看看有没有正常启动 CLR。咱们不需要安装串口工具,在 VS Code 的扩展里面就有,叫 Serial Monitor,属于微软大法的一种。安装扩展后打开终端面板,你会看到有个串口监视器,切换过去,选择串口号,点击【开始监视】即可。 C、你会发现 ESP32 在无限重启。停止串口监视后查看错误。
上传并打开“串口监视器 (Serial Monitor)”窗口,检查一切是否正常。 要激活系统,只需输入我的默认密码“1234”,警报将在8秒内启动(也可以在代码中对此进行更改)。 #include <Keypad.h>[/align]#include <WiFi.h> #include <WiFiMulti.h> #pragma region Globals ...
(using v. 2.0.4, on Win11 PC). I was expecting to use response on Serial Monitor to confirm that things were working. I'm not sure exactly what made it suddenly function as expected. But when I searched for pin numbers for onboard LEDs, I noticed from a review of the luatos board...

第五步,通过I2C LCD连接ESP32 BMP180。虽然Serial Monitor能够显示测量的大气压和温度数,但是并不实用。本项目采用PCF8574 I2C LCD模块与16×2字节LCD显示器,显示来自ESP32 BMP180传感器接口的数据。 显示屏和I2C LCD模块(PCF8574)是分开的,需要将LCD模块插入16×2 LCD显示器的背部,而LCD模块的连接引脚只有4个(...
