最近在开发过程中，用到了Arduino开发板以及其IDE:Arduino,这个IDE使用起来很方便，编码也很简单，但有一点美中不足的是Arduino只能输出数值，不能绘图，所以就用到了另外一款串口调试软件----SerialChart.
废话不多说，直接上程序。
Arduino程序
1 void setup() { 2 // put your setup code here, to run once: 3 Serial.begin(9600); 4 } 5 6 void loop() { 7 // put your main code here, to run repeatedly: 8 int sensorValue0=analogRead(A0); 9 sensorValue0=sensorValue0*4; 10 int sensorValue1=analogRead(A1); 11 sensorValue1=sensorValue1*4; 12 int sensorValue2=analogRead(A2); 13 sensorValue2=sensorValue2*4; 14 15 Serial.print(sensorValue2,DEC); 16 Serial.print(','); 17 Serial.print(sensorValue0,DEC); 18 Serial.print(','); 19 Serial.print(sensorValue1); 20 Serial.print(","); 21 Serial.println(" "); 22 delay(100); 23 }
这里需要注意的是在每行最后一个数据出后，首先要打印逗号，再打印换行符，我看其他很多教程上都没有逗号，这样就会使最后一个数据无法绘制图形
Arduino配置文件

运行结果，
