因此，digitalWrite(LEDpin, state) 函数的意思是，将 state 指定的电平写入 LEDpin 指定的数字引脚。在 Arduino 程序中，`serial.println(state)` 是一个函数，用于将变量 `state` 的值输出到串行端口。这个函数在 Arduino 中预定义好了，可以直接使用。`serial.println(state)` 函数会将变量 `state...
pinMode(CLK_PIN,输入);// 将引脚设置为输入 pinMode(DATA_PIN,输入); pinMode(BTN_PIN,INPUT_PULLUP); clockPinState = digitalRead(CLK_PIN); pinMode(SET_FREQUENCY_HZ, INPUT);// 将引脚设置为输入 pinMode(SET_FREQUENCY_KHZ,输入); pinMode(SET_FREQUENCY_MHZ,输入); pinMode(ENABLE_DISABLE_OUTPU...
这是一个抽象函数，其作用是向指定的数字量接口写入数据。在这个例子中，要写入的数字量接口是LED对应的管脚，写入的数据是目标状态，亮或灭。
