下面把最后测试的示例代码放上(代码是以测试为目的,没有把读取ID的部分代码写成函数,有点不太规范): /\* UART asynchronous example, that uses separate RX and TX tasks This example code is in the Public Domain (or CC0 licensed, at your option.) Unless required by applicable law or agreed to i...
using, be sure to use another PWM capable pin. On most Arduino, the PWM pins are identified with a "~" sign, like ~3, ~5, ~6, ~9, ~10 and ~11. This example code is in the public domain. https://www.arduino.cc/en/Tutorial/BuiltInExamples/Fade */ int led = 12; // the ...

vscode找不到arduinoide解决方法如下:1、下载安装ArduinoIDE,VSCode编译时还是需要ArduinoIDE提供的一些工具链。2、在VSCode的插件列表里,搜索安装arduino插件:安装完成后,点重新加载按钮,,即可启动arduino扩展。3、配置Arduino插件:文件菜单,首选项,设置,打开VisualStudioCode配置文件,在右侧尖括号内 ...
To change the ESP32 MAC address in Arduino IDE, you can use the esp_wifi_set_mac()function from the esp_wifi.h library. Which takes the WiFi mode and the MAC address array as arguments. Here is an example code for MAC Address change to a custom address in Arduino IDE....
