基于STC89C52的oled红外遥控闹钟
这个红外遥控主要是程序通过对按下的键的键码进行解析，并运行相应的功能代码
一次按键动作的遥控编码信息为 32 位串行二进制码。对于二进制信号“0”，一个脉冲占 1.2ms；对于二进制信号“1”，一个脉冲占 2.4ms，而每一脉冲内低电平均为 0.6ms。从起始标志到 32 位编码脉冲发完大约需80ms，此后遥控信号维持高电平。若按键未释放，则从起始标志起每隔 108ms 发出 3 个脉冲的重复标志。在 32 位的编码脉冲中，前 16 位码不随按键的不同而变化，我们称之为用户码。它是为了表示特定用户而设置的一个辨识标志，以区别不同机种和不同用户发射的遥控信号，防止误操作。后 16 位码随着按键的不同而改变，我们就是要读取这 16 位按键编码，经解码得到按键键号，转而执行相应控制动作。
主要运用DS1302时钟芯片，红外遥控，oled显示屏，蜂鸣器，定时器，中断实现
研究过程：
1.工程的建立和文件存放分配
2.根据原理图进行全局参数，引脚申明，类型说明头文件的编写
3.功能模块调试
1>oled液晶显示屏功能调试
2>蜂鸣器功能调试 //定时器2
3>DS1302读写调试
4>红外遥控按键功能的调试 //定时器1和外部中断0
4.所有显示程序的调试
5.程序总体功能的调试
7引脚的oled接线：
GND接GND，VCC接VCC，D0，D1，RST，DC接自定义引脚，CS接地。
