GPIO_ReadInputDataBit(GPIO_TypeDef*GPIOx,u16 GPIO_Pin); 功能:读取指定端口管脚的输入 参数:GPIOx :x 可以是A,B ,C ,D 或者E,来选择GPIO外设 GPIO_Pin:待读取的端口位 返回值: 输入端口管脚值 例子:ReadValue=GPIO_ReadInputDataBit(GPIOA,GPIO_Pin_0); //Readsthe seventh pin of the GPIOB and store...
Although you can define the pins properties on the software, there are pins assigned by default as shown in the following figure (this is an example for theESP32 DEVKIT V1 DOIT boardwith 36 pins – the pin location can change depending on the manufacturer). Additionally, there are pins wit...

rshell -p /dev/ttyUSB0 若开发板两个开关管没焊,还需要加--rts 0 --dtr 0 使用rshell取得ESP的python shell 在rshell模式下执行: repl 使用rshell在ESP和电脑之间互传文件 通过传文件来更新ESP上的.py文件,相当于可以OTA 主要要使用的就是rshell内的cp命令(复制)。进入rshell后直接操作的仍是电脑系统...
pin选择 GPIO 引脚。 true如果分离成功,该函数将返回。如果false返回,则发生错误并且引脚未分离。 应用示例 以下是 SigmaDelta 的使用示例: 文件-> 示例 -> ESP32(ESP32 S3 Dev Module 的示例) -> AnalogOut -> SigmaDelta 。 ESP32 S3 Dev Module 的示例 SigmaDelta ...
