摘要
定时器在工业和家用电器控制等方面得到了广泛应用。介绍了以AT89C2051单片机为核心的实用定时器。采用AT89C2051和LED数码管,具有功耗低、体积小、连续可调、容易制作、价格低廉等特点。给出了定时器硬件电路图设计和软件流程图,阐述了硬件和软件设计过程中关键技术的处理。该定时器在用户中试用性能稳定,且设计精巧、成本低、实用性强。
The timer has been widely used in industrial and home appliance control. The practical timer whose core is the AT89C2051 single chip is introduced. The use of AT89C2051 and LED digital tube is characterized by its low power consumption, small volume and low price. Besides, it is continuously adjustable and easy to make. The hardware circuits and main program diagrams of the timer are presented, and the key techniques in design of hardware and software are also de- scribed. The timer is in the use trial stable performance, ckmpact design,low ckst and high practi- cality.
