c – 向Arduino发送字符串的最佳方式？

从主机向Arduino发送和接收字符串的常用方法是使用Arduino的串行库.串行库通过与计算机的连接一次读取和写入一个字节.

下面的代码通过附加通过串行连接接收的字符来形成一个字符串：

// If you know the size of the String you're expecting,you could use a char[]
// instead.
String incomingString;

void setup() {
  // Initialize serial communication. This is the baud rate the Arduino
  // discusses over.
  Serial.begin(9600);

  // The incoming String built up one byte at a time.
  incomingString = ""
}

void loop() {
  // Check if there's incoming serial data.
  if (Serial.available() > 0) {
    // Read a byte from the serial buffer.
    char incomingByte = (char)Serial.read();
    incomingString += incomingByte

    // Checks for null termination of the string.
    if (incomingByte == '') {
      // ...do something with String...
      incomingString = ""
    }
  }
}

要发送串行数据—并打印出Arduino打印的数据—您可以使用Arduino IDE中的串行监视器.
