analogWrite(pin, val) – 设置数字管脚中的PWM管脚的输出值,val取值为0-255 Serial.begin(speed) – 初始化串口并设置串口速率,如Serial.begin(9600); 即将串口速率设置为9600bps Serial.print()/Serial.println() – 串口输出函数 delay(val) – 延时函数,单位为ms,如delay(1000)为延时1s Arduino的编程与C...

Arduino Analog Output: From Basics to Applications Many chips use a serial interface to reduce the number of physical pins, so instead of using a parallel processor bus to transfer data 8 or 16 bits at a time, two signals (clock and data) get data from the device, one bit at a time....

如果未使用Serial1并且未交换Serial-UART0的TX可以通过在Serial.begin之后调用Serial.set_tx(2)或直接通过Serial.begin(baud,config,mode,2)将UART0的TX引脚映射到GPIO2(D4)。 默认情况下,调用Serial.begin(),WiFi库的诊断输出是禁用的。要启用调试输出,需要调用 Serial.setDebugOutput(true)。要将调试输...
