基于单片机AT89C51的7只LED显示十进制数码的设计与实现

笔者利用单片机引脚输出信号驱动多个指示灯,控制设备的显示状态,进一步掌握了单片机对端口输出电平的控制。控制程序设计完成后,一方面可以通过Proteus软件仿真测试控制效果;另一方面可以通过烧写单片机芯片,在硬件电路上测试控制效果。通过仿真和硬件验证,旨在加深对单片机控制系统硬件电路的认知,同时也可熟悉和强化控制程序的设计。

The author uses the single-chip pin output signal to drive a plurality of indicator lights to control the display state of the device,and further grasps the control of the output level of the port by the single-chip microcomputer.After the design of the control program is completed,on the one hand,the control effect can be simulated by Proteus software;on the other hand,the control effect can be tested on the hardware circuit by programming the single chip.Through simulation and hardware verification,the aim is to deepen the understanding of the hardware circuit of the microcontroller control system,and also to familiarize and strengthen the design of the control program.
