关于串口输出格式的小问题

本帖最后由 １９００ 于 2013-12-8 23:27 编辑

传感器的三个模拟信号输入Mango2的A0，A1，A2端，串口输出数字信号，想让一条数据的三个值在同一行显示
一下是我的代码
void loop() {
// read the input on analog pin 0:

int sensorValue0 = analogRead(A0);
int sensorValue1 = analogRead(A1);
int sensorValue2 = analogRead(A2);
// print out the value you read:
   a = ++a;
Serial.print(a);
Serial.print(".");
Serial.println(sensorValue0);
Serial.print(".");
Serial.println(sensorValue1);
Serial.print(".");
Serial.println(sensorValue2);
delay(200);      // delay in between reads for stability
}
用串口监视器查看输出，看到自动换行了（如下），请问怎样让一条数据三个值在一行里面显示？
12.0
.0
.62
13.188
.0
.592
14.478
.28
.273
15.468

将值输出到一个 string 中然后一起输出试试看
   char buf;               //Output buffer
      snprintf(buf, sizeof(buf), "%d %d" value1,value2);      
      lcd.print(buf);

void loop() {
// read the input on analog pin 0:

int sensorValue0 = analogRead(A0);
int sensorValue1 = analogRead(A1);
int sensorValue2 = analogRead(A2);
// print out the value you read:
   a = ++a;
Serial.print(a);
Serial.print(".");
Serial.print(sensorValue0);
Serial.print(".");
Serial.print(sensorValue1);
Serial.print(".");
Serial.println(sensorValue2);
delay(200);      // delay in between reads for stability
}

原来print是接着输出，println是换行输出，多谢指教！
