步骤1:Doit ESP32 Devkit V1开发板 在电路方面,我选择了低成本的Doit ESP32 Devkit V1开发板,它提供了无线通信选项,比如WiFi、蓝牙和ESP-NOW。 在这个项目中用的ESP32板模型总共有30个I/O引脚。有些型号有36个I/O引脚,并且尺寸较长。Doit ESP32 Devkit V1开发板可以通过VIN引脚以4V到12V的供电电压工作。
ESP32 Pinout There are different types of ESP32 development kits available but the function of GPIO pins remains the same across all development boards. You can define the pins the same way in firmware also. The following picture shows the pinout diagram of the ESP32 DEVKIT V1 DOIT board. ...
虽然您可以在软件上定义引脚属性,但默认分配的引脚如下图所示(以ESP32 DEVKIT V1 DOIT板36引脚为例-引脚位置可以根据制造商而改变)。 ESP32 片上存储信息: • 448 KB 的 ROM,用于程序启动和内核功能调用. • 用于数据和指令存储的 520 KB 片上 SRAM. • RTC 快速存储器,为 8 KB 的 SRAM,可以在 D...
