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....

在Arduino ESP32-CAM 学习之旅① 认识ESP32-CAM,搭建环境,运行第一个程序 中,我们仅仅是运行了一个官方例程,但是对于好学的我们来说,还是想慢慢拆解整个代码模块,拆解成我们可以理解的各个部分。所以,这一篇,请跟着博主去揭开ESP32-CAM的神秘面纱。官方案例的操作步骤: 下载案例到ESP32-CAM,主要烧写注意事项 在电...
ESP32 PWM Outputs Control (in Arduino) You can use the ESP32 PWM pins to control many devices ranging from small LEDs and up to high-power motors using MOSFET drivers and things like that. In this section, I’ll give you a step-by-step approach for what to do in order to configure...
1.Arduino程序中没有main函数,main函数隐藏在Arduino的核心库文件中,开发时一般不直接操作。 2.Arduino代码结构中有两个主要函数 setup() loop() Arduino 数学函数 Arduino数学库(math.h)包含了许多用于操作浮点数的有用的数学函数 第二章 系统时间和定时任务调度器Ticker ...
本文需要使用的Arduino库如下: 配置流程大致如下: 添加成功后可以在工程目录下看到已添加的库,platformio.ini文件中也会自动生成依赖库代码。 2.3 配置LCD底层接口 2.3.1 LCD接口配置 TFT_eSPI库集成了很多常用LCD驱动IC的接口,根据自己使用的LCD屏幕参数修改User_Setup.h文件,即可调用底层的接口函数。
