如果设置了ethernet模式,别忘记了还需要到Top - Component config - Ethernet - Support ESP32 internal EMAC controller修改以太网的引脚、时钟频率。 在Top - Example Configuration中配置esp32客户端要连接IP地址和端口。这里我设置我自己电脑的IP地址和端口,那就可以实现互连了。如下图。 如果你设置没有问题,然后...

Arduino应用开发——esp32lvgl v8.3环境搭建 2.2 移植UI文件 打开上面GUI-Guider的工程目录,custom和generated文件夹里面全部都是UI相关的文件,我们把这些文件移植到ESP32的工程里面即可。 在ESP32工程的src文件夹(也就是main.cpp所在目录),新建一个文件夹用来存放UI文件,名字随意(我这里命名为lvgl_ui)。
This example shows how to fade an LED on pin 9 using the analogWrite() function. The analogWrite() function uses PWM, so if you want to change the pin you're using, be sure to use another PWM capable pin. On most Arduino, the PWM pins ...

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。
