求助！arduino红外遥控和超声波数码管显示测距两段程序合在一起上传无法运行
求助大神，两段程序分别上传运行良好，但是把代码合在一起，loop函数中的内容合在一起后上传功能却无法正常实现，是为什么？代码如下：
超声波测距

pinMode(b, OUTPUT);
pinMode(c, OUTPUT);
pinMode(d, OUTPUT);
pinMode(e, OUTPUT);
pinMode(f, OUTPUT);
pinMode(g, OUTPUT);
pinMode(p, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
float a;
a = getLength();
Serial.print(a);
Serial.println("cm");
cmbig = (int) (a * 10);
w1 = cmbig/1000;//百位上的数字
w2 = (cmbig)%1000/100; //十位上的数字
w3 = (cmbig)%100/10; //个位上的数字
w4 = cmbig%10; //小数点后一位上的数字
for(i=0;i<50;i++)
SHOW();
}
//测距函数
float getLength()

请问是不是上面两个分开的程序loop函数中内容合起来顺序安排不合适，如果是，该怎么做呢？ 哪有那么简单，整合程序比单独的难多了
