基于STC89C52的oled红外遥控闹钟

作者:互联网

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。
