SofaWareSerial() 功能:这是SoftwareSerial类的构造函数,通过它可以指定软串口的RX和TX引脚 语法:SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin) listen() 功能:开启软串口监听状态 arduino在同一时间仅能监听一个软串口,当需要监听某一串口时,需要对该对象调用此函数开启监听功能 overflow() 功能:检测缓冲...

4.15. Setting Up Processing on Your Computer to Send and Receive Serial Data Problem You want to use the Processing development environment to send and receive serial data. Solution You can get the Processing application from the Downloads section of the Processing website, http://processing.org...
Now, in order to establish the serial communication with the ESP32 over Bluetooth, we will need an additional serial monitor, so we can send the data to the device. Although we can open a new instance of the Arduino IDE and open a new terminal for the Bluetooth emulated COM port, I’...
When you use the Serial monitor, well, basically your Arduino IDE initiates a Serial communication with your Arduino. You can receive and send data directly from the Serial monitor.What we’ll do here is almost the same, except that instead of your Arduino IDE, the other side of the ...
