ESP32-DevKitC V4 是 乐鑫 一款基于 ESP32 的小型开发板,板上模组的绝大部分管脚均已引出,开发人员可根据实际需求,轻松通过跳线连接多种外围器件,或将开发板插在面包板上使用。 为了更好地满足不同用户需求,ESP32-DevKitC V4 还支持以下不同配置: 可选多款 ESP32 模组 ESP32-WROOM-32D ESP32-WROOM-32U ...
以build.variant=esp32为例。在 variants 文件夹里面找到 esp32 文件夹,打开里面的pins_arduino.h。再结合仓库里的 README.md 底下的 PINMAP,就能知道pins_arduino.h里面配置的含义了。 图2:引脚配置文件里的数字与开发板引脚的对应关系 从上图看出,数字不是乱选的。这些数字分别对应了通用输入/输出引脚(GPIO,G...

On my ESP32-DevkitC V4 the LED that is attached to the PCB is always ON. According to the docs "5V Power On LED" is described as "Turns on when the USB or an external 5V power supply is connected to the board." In my case though it is ON even when powered by 3.3V pin. In...

Re: ESP32-C3-DevKitC-02 SPI issue PostbyESP_Sprite»Fri Apr 12, 2024 3:38 am FWIW, I see nothing wrong with your code... I assume running it does not spit out any errors? Perhaps you're measuring the wrong pins or something?
我这边又重新用ESP32_DevKitc_V4测试了一遍,如果GPIO39悬空什么都不接确实不会持续进入中断,但如果上面接根杜邦线就能看到中断被持续触发。另外我之前的问题出现条件是外接了上拉电阻,我估计可能和这个有关。huagui Posts: 1 Joined: Sat Jan 15, 2022 5:15 am Re: esp32 ble开启后,导致GPIO39中断不正常...

备注,文档中我都是以我自己的开发板为基准的,我的板子是ESP32-DevKitC V4,有不一样的需要自行找到自己的开发板文档。 首先得思考一个问题,就是,点亮LED的原理,灯要亮,那么肯定得有电流通过,如果从没有接触过开发板的,虽然也写了几年程序,一开始肯定是云里雾里的,实际上我一开始也是云里雾里的。
