编码信息红外发射与接收器

Emitter and Receiver of Infrared with Coding Information

介绍一种基于MCS-51单片机的红外信号发射与接收器。它结合专用集成芯片的优点,获得稳定、可靠的发射脉冲。充分利用单片机的内部资源,依靠程序的驱动,实时、稳定地完成信号的发射及接收显示。发射电路的按键部分可扩展为32个或更多按键,满足不同用户的需求。

The emitter and receiver of infrared based on MCS-51 are introduced in this paper. The merits of the IC are combined in the device in which emission pulse is produced steadily and reliably. Making full use of the resources of single-chip microcomputer, depending on the drive of programmer, the emission and display of encoding signal are completed. In order to satisfy the different requirement, the keys of the emission circuit could be extended as many as 32 and more keys.
