Description: 具有定时功能的八路数显抢答器的设计
本文介绍了一种用74系列常用集成电路设计的数码显示八路抢答器的电路组成、设计思路及功能。该抢答器除具有基本的抢答功能外，还具有定时、计时和报警功能。主持人通过时间预设开关预设供抢答的时间，系统将完成自动倒计时。若在规定的时间内有人抢答，则计时将自动停止；若在规定的时间内无人抢答，则系统中的蜂鸣器将发响，提示主持人本轮抢答无效，实现报警功能。
-With regular features eight-way digital design Answer This paper introduces a series of 74 commonly used integrated circuit design of digital display devices Answer eight-way circuit design and functions. In addition to the browser Answer Answer basic functions, also has the timing, timing and alarm functions. Host through the default time for switching the default Answer time, the system will automatically countdown to complete. If the required timeframe was Answer, then the time will automatically stop if within the required timeframe Answer No, the system will be sent the buzzer ring, suggesting that the current round of presenters Answer invalid realize alarm function.

Description: 遥控器使用方便，功能多．目前已广泛应用在电视机、VCD、DVD、空调等各种家用电器中，且价格便宜，市场上非常容易买到。如果能将遥控器上许多的按键解码出来．用作单片机系统的输入．则解决了常规矩阵键盘线路板过大、布线复杂、占用I／O口过多的弊病。而且通过使用遥控器，操作时可实现人与设备的分离，从而更加方便使用。下面以TC9012编码芯片的遥控器为例。谈谈如何用常用的51系统单片机进行遥控的解码。-Remote easy to use, features and more. Has been widely used in TV, VCD, DVD, air conditioning and other household appliances, and the price cheap, the market is very readily available. If you can remote control many of the key decoder out. Single-chip microcomputer system used for input. The solution of conventional keyboard matrix circuit board is too large, complex wiring, occupied by I/O port too many ills. But also through the use of remote control operation can realize the separation of people and equipment, thus more convenient to use. The following code to TC9012 chip remote control as an example. To talk about how to use the 51 commonly used system for remote control single-chip decoder.
