北京科技大学自动化学院微机课程设计（报告）
Abstract
Course design (microcomputer principle) is the design course of "Microcomputer
Principle and interface technology", which is an important professional practice link of
automation specialty. Through the course design of microcomputer principle, we can
review the learned professional knowledge of analog electronic technology, digital
electronic technology, microcomputer principle and interface technology, and
organically combine the theoretical knowledge and practice to finally design the
infrared remote control device with correct principle and complete function.
Through the course design, we can make a comprehensive understanding of
theoretical knowledge and cultivate students' ability of system design, which can be
achieved as follows: the ability to investigate and analyze problems; the ability to use
design manuals and technical specifications; the ability to consult Chinese and foreign
literature; the ability to formulate design schemes; the ability to use computers; the
ability to design calculations and drawings; the ability to express words and languages
Ability.
Understand the basic process of system design, on the basis of the teacher's
explanation, consult relevant materials, determine the design task, select and design the
system hardware according to the design task, draw the hardware wiring diagram,
program and debug the software according to the design task, and summarize the
development experience through the design.
First of all, through the basic seven segment nixie tube experiment, keyboard
display control experiment, two-color lattice LED display experiment, 128X64
character graphic LCD experiment, 128X64 character graphic LCD experiment, the
realization method of the basic functions is mastered, which lays the foundation for the
design of the follow-up infrared remote control module. The infrared remote
control module is composed of infrared transmitter, infrared receiver, seven segment
digital tube and LCD. Press the key on the infrared transmitting device, the infrared
receiving module will display the corresponding number by decoding, and the seven
segment nixie tube and liquid crystal display screen will display different contents
according to the different status of transmitting and receiving.
According to the design requirements, we can select appropriate chips, such as
CPU, memory, count timer, serial / parallel interface chip, a / D, D / A, programmable
interrupt controller chip and other auxiliary chips, and design a reasonable hardware
system design scheme to complete the system wiring diagram. According to the
software system design specification, complete the drawing of the program flow chart,
the preparation of the program, and complete the debugging and operation of the
