在Arduino上从串行通信中读取特定行的有效方法

#include <Arduino.h>

const int bufferSize = 64;
char buffer[bufferSize];
int bufferIndex = 0;
bool newLineFound = false;

void setup() {
  Serial.begin(9600); // 初始化串行通信波特率为9600
}

void loop() {
  if (Serial.available() > 0) {
    char incomingChar = Serial.read();

    if (incomingChar == '\n') {
      newLineFound = true;
      buffer[bufferIndex] = '\0'; // 添加字符串结束符
    } else {
      if (bufferIndex < bufferSize - 1) {
        buffer[bufferIndex++] = incomingChar;
      }
    }

    if (newLineFound) {
      processLine(buffer);
      bufferIndex = 0;
      newLineFound = false;
    }
  }
}

void processLine(char* line) {
  // 在这里处理读取到的行数据
  Serial.print("Received line: ");
  Serial.println(line);
}
