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...

Re: ESP32-DevkitC V4 LED allways on PostbySprite»Fri Dec 13, 2019 1:30 am I'd say the AMS1117 is your culprit. The datasheet talks about an internal diode between the output and the input; that would backfeed the 5V line with 3.3V if you only power it via 3.3V. ...
C:\ProgramFiles\Espressif 安装完成后,会得到两个ESP_IDF终端 ,如下图所示: 在这两个终端任选其一,打开终端时会自动添加ESP-IDF的环境变量,之后就可使用 idf.py 命令进行操作了。如下图所示: idf.py 使用idf.py 工具进行开发,参见: https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/get-...

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。
Re: ESP32-S3-DEVKITC ADC Pins Error (Question)Quote by TestIt » Wed Aug 24, 2022 11:06 pm The fact that an unconnected analog input pin has its value set by the ambient environment makes it useful as a random number generator (but not so much for the purpose of security)....

ESP32-DevKitC V4 is a small-sized ESP32-based development board produced by Espres-sif. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-DevKitC V4 on a breadboard. ...
