SoftwareSerial Library 现有的Arduino硬件支持引脚0和1(通过USB连接到到电脑)进行串行通信。串行通过一个称为 UART 的硬件(芯片内置)进行。这个硬件允许ATMEGA芯片接收串行通信,即使芯片在进行其他工作,只要有64个字节的串行缓冲器的储存空间即可。 使用软件的串口功能(因此称为“SoftwareSerial”,即“软串口”),现有的...
Software Serial Library 使能数字引脚上的串行通信,更多的信息参考the Reference for the Software Serial Library page。适用于所有Arduino板,除了Arduino DUE。 Software Serial Example: 使用这个库…因为有时一个串行端口是不够的! Two Port Receive: 和多个软件串口工作。
在C++代码中,我有一个SerialClass.h和一个Serial.cpp 我的问题是我得到了一个编译器错误:函数中未定义的标识符"SP“ void Serial::SendtoArd(int val, int var) { if (SP->IsConnected()) { bool writeData = false; writeData = SP->WriteData("test",4); } 我知道如果我在这个函数中定义...

When working with ESP32 WiFi/Bluetooth MCU under Arduino SDK for ESP32, you will notice that Serial work just fine. But Serial1 and Serial2 do not. ESP32 has 3 hardware serial ports that can be mapped to almost any pin. But, Serial1 and Serial2 will not
Serial.println("Data from port one:"); // while there is data coming in, read it // and send to the hardware serial port: while (portOne.available() > 0) { char inByte = portOne.read(); Serial.write(inByte); } // blank line to separate data from the two ports: ...

A New Software Serial Library for Arduino News:NewSoftSerialis in the core! Starting with Arduino 1.0 (December, 2011), NewSoftSerial has replaced the old SoftwareSerial library as the officially supported software serial library. This means that if you have 1.0 or later, you shouldnotdownload thi...
