如果编译出现类似的错误,error: 'LED_BUILTIN' was not declared in this scope,原因是LED_BUILTIN没有被申明,你可以直接使用esp32的pin number直接更换,我有块板子把LED_BUILTIN改成2就可以点亮了。 esp32相关文章和视频: eyeglasses:esp32 wifi 连接控制LED灯11 赞同 · 0 评论文章 eyeglasses:esp32连接温...

Hello, I am transferring a ESP32 WROOM code to a C3. I updated all the pins to my new configuration (missed a few the first time) but when the C3 tries to boot, it gets stuck in a booting loop (see below). I did some research, and it looks like this is likely a pin mapping...

首先你需要一块ESP32开发板,本人使用的是一块ESP32-WROOM-32核心板,关于ESP32各个型号的区别可以进入乐鑫官网查看。 然后准备一块屏幕,我使用的是一块2.8寸(240*240)的tft屏幕,驱动是ST7789,使用spi通信协议。 二、软件准备这里我使用的是vscode 的PlatformIO插件 新建文件,选择开发板为DOIT ESP32 DEVKIT V1,...
