红外线根据温度控制空调和风扇的代码问题请教

zhuangpeng

代码如下：
========================================================
//The LED sender must connect to 3 pin
#include <OneWire.h>
#include <DallasTemperature.h>
#include <IRremote.h>

// Data wire is plugged into port 2 on the Arduino
#define ONE_WIRE_BUS 4

// Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);

===============================================
实现功能：
通过温度检测，高于30度启动空调，低于30度启动风扇
问题：
运行后串口没有输出，就连SETUP()中的Serial.println()都没有输出结果。但屏弊掉任意两个 irsend.sendRaw 就运行正常了。
请大家帮我看一下问题出现在什么地方？谢谢！

没人帮帮我吗？

试了一下，但是不会，不过我这几天正做空调的红外解码呢，我想把每个温度每个状态都弄出来，但是单片机内存不够，正苦恼呢，这些解码都有规律吗

有的時候抓出來的數字稍微有誤差，稍微整理一下還是可以
建議先做個簡單程序單純發送，確定抓下來的碼沒問題再來找規律
格力空調我用9000+4400開頭，訊號段650+550跟650+1600，結尾650+40000可以發送

内存不够？
试着搜下我的帖子，把你的数据定义到flash里面。
