Aduino 문자열에서 아이디와 값을 매핑시키기 String to sscanf

  

String readString​ = "1:20,3:20,5:100,12:5";
  int id1, id2, id3, id4;
  int pos1, pos2, pos3, pos4;
  int buf_len = readString.length() + 1;
  char buf[buf_len];
  readString.toCharArray(buf, buf_len);
  
  int n = sscanf(buf, "%d:%d,%d:%d,%d:%d,%d:%d", &id1, &pos1, &id2, &pos2, &id3, &pos3, &id4, &pos4);
  
  Serial.print(F("n="));
  Serial.println(n);
  Serial.print(F("id1="));
  Serial.print(id1);
  Serial.print(F(", pos1="));
  Serial.println(pos1);
  Serial.print(F("id2="));
  Serial.print(id2);
  Serial.print(F(", pos2="));
  Serial.println(pos2);
  Serial.print(F("id3="));
  Serial.print(id3);
  Serial.print(F(", pos3="));
  Serial.println(pos3);
  Serial.print(F("id4="));
  Serial.print(id4);
  Serial.print(F(", pos4="));
  Serial.println(pos4*1000);
