本次设计中以单片机的发展过程和发展方向为背景,介绍了单片机的输入输出的工作原理和操作方法,中断的工作原理和操作方法.4511的工作原理和操作方法,LED的内部结构.电路设计及调试过程. 本次做的数字钟是以单片机(AT89C51)为核心,结合相关的元器件(共阴极LED数码显示器、BCD-锁存/7段译码/驱动器CC4511等),再配以相应的软件,达到制作简易数字钟的目的,其硬件部分难点在于元器件的选择、布局及焊接. 关键词:单片机 AT89C51 共阴极LED数码显示器 BCD-锁存/7段译码/驱动器CC4511 Abstract In recent years, with computers in the infiltration and the development of large-scale integrated circuits. SCM application is steadily deepening, as it has strong function, small size, low power dissipation, low prices, reliable, easy to use features, it is particularly suited to and control of the system, increasingly widely used in automatic control, intelligent instruments, gauges, data acquisition, military products and household appliances, and other areas, is often microcontroller as a core component to use, In light of specific hardware architecture, and application-specific software features object combine to make perfect. The design of a microcontroller development process and the direction of development as the background, the computer'
s input and output of the working principle and method of operation interrupted the principle and method of operation. 4511, the principle and method of operation, LED internal structure. Circuit design and debugging process. The figures do bell on SCM (AT89C51) at the core, Combined with the components (a total of cathode LED digital display, BCD - latch /7 of decoding / actuator CC4511), and factoring in the corresponding software, Easy to produce digital clock purposes, as part of the hardware components is a difficult choice, layout and welding. Keywords : Single Chip Microcomputer AT89C51 Total cathode LED figures display BCD-the lock save/7 the segments translate code/actuator CC4511 目录 摘要 -
