红外发射问题【arduino pro mini + 红外发射管（LED） + nRF24L01】

xiaoesky

设备：arduino pro mini + 红外发射管（LED） + nRF24L01

原理：arduino pro mini通过nRF24L01接收到开关指令后，再由红外发射管控制空调开关。

问题：

先看两组代码：

代码1：
//定义三个数组，分别是关、开、温度设定。
unsigned int turn_off[212] = {8950,4400,600,1600,600,1600,600,500,600,500,550,500,600,500,600,1600,600,1650,550,1650,550,1650,550,1600,600,500,600,500,600,500,550,1650,600,1600,550,550,550,500,600,500,600,500,600,500,550,500,600,500,600,500,550,550,550,500,600,500,600,500,600,500,550,500,600,500,600,500,600,500,550,550,550,500,600,500,600,500,550,1650,600,500,550,550,550,500,600,500,600,500,550,500,600,550,600,450,600,1600,550,550,550,500,600,500,600,500,600,500,600,500,550,1650,550,500,600,500,600,500,600,500,550,500,600,500,600,500,600,500,550,550,550,550,550,500,600,500,600,450,600,500,600,500,600,500,600,500,600,450,600,500,600,500,600,500,600,450,600,500,650,400,650,500,550,500,600,550,550,500,550,550,550,550,550,500,600,500,600,500,600,500,550,1650,550,550,550,1650,550,450,650,500,600,500,600,450,600,500,600,1650,550,1600,600,1650,550,1600,600,500,600,500,550,550,550,500,600,25546};

//通过nRF24l01接收到指令后，再由红外控制空调

    switch(val)
    {
      case 1:irsend.sendRaw(turn_off,212,38);irsend.sendRaw(turn_off,212,38);break;    //关空调
      case 2:irsend.sendRaw(turn_on,212,38);irsend.sendRaw(turn_on,212,38);break;    //开空调
      case 3:irsend.sendRaw(set_temp,212,38);irsend.sendRaw(set_temp,212,38);break;    //设定温度为26度  
     }

以上代码调试正常，没问题。但把代码改为代码2这样就出问题了，无法控制空调了，请各位高人指点与解决。

代码2：
//定义三个数组，分别是关、开、温度设定，跟代码1没变化。

     }

删除了“delay(500);”代码也是一样无法开/关空调与设定温度。

电子爱好者

是不是中间间隔太短了
开机后是不是应该等待的时间长一点再设置温度

我才参照了你的建议，采用这种方式把数据存放到flash中：
PROGMEM unsigned int set_temp[212] = {8950,4450,550,1600,600,1650,550,550,550,500,600,500,550,550,550,1650,550,1650,550,1650,550,1650,550,1650,550,550,550,1650,550,550,550,500,600,1600,600,500,600,500,550,550,550,500,600,500,600,500,550,550,550,550,550,500,600,500,550,550,550,550,550,500,600,500,550,550,550,550,550,500,600,500,600,500,550,550,550,500,600,1600,600,500,600,500,550,550,550,500,600,500,600,500,550,550,550,550,550,1650,550,500,600,500,600,500,550,550,550,500,600,500,600,1600,600,500,550,550,550,500,600,500,600,500,550,550,550,550,550,500,600,500,550,550,550,550,550,500,600,500,600,500,550,550,550,500,600,500,600,500,550,550,550,500,600,500,600,500,550,550,550,1650,550,550,550,500,600,500,550,550,550,550,550,500,600,500,600,500,550,550,550,500,600,500,600,500,550,550,550,500,600,500,600,500,550,550,550,500,600,500,600,1600,600,500,550,1650,600,1600,600,1600,600,1600,600,1600,600,18540};

然后我要使用这些数据，是不是要做一个循环？读取到数组set_temp[212]中？这样才能使用这组数据吗？
