Practical training board for single-chip microcomputer teaching

Abstract

Provided is a practical training board for single-chip microcomputer teaching. The practical training board for single-chip microcomputer teaching is open and comprises a single-chip microcomputer minimum system and a peripheral functional circuit. The single-chip microcomputer minimum system comprises a single-chip microcomputer, a first crystal oscillator circuit and a reset circuit. The peripheral functional circuit comprises an interrupt signal circuit, a buzzer circuit, a seven-segment display circuit, a first drive circuit, a second drive circuit, a keyboard circuit, a dot matrix LED display circuit and a USB program downloading circuit. The practical training board is simple, open, stable in function and not prone to breakdown or system halted or the like, meanwhile the circuits are clear at a glance, and beginners can more conveniently know and learn the single-chip microcomputer. Programs are downloaded through the USB program downloading circuit without being limited by the distance or other limitation, and the programs can be more conveniently downloaded.

Description

technical field [0001] The invention relates to the technical field of single-chip microcomputers, in particular to a teaching and training board for single-chip microcomputers. Background technique [0002] Single-chip microcomputer is an integrated circuit chip, which uses VLSI technology to integrate a central processing unit (CPU), random access memory, read-only memory, various I / O (input / output) ports and interrupt systems with data processing capabilities. A small but complete microcomputer system composed of functions integrated on a silicon chip is widely used in various fields of life. [0003] There are many traditional 51 series single-chip microcomputer teaching and training devices. These single-chip teaching and training devices are powerful, integrating development, simulation, and practical training, and have a wide range of applications. However, these single-chip training devices are complete sets of equipment, with relatively tight packaging, complex int...

AI Technical Summary

Problems solved by technology

However, these single-chip training devices are complete sets of equipment, with relatively tight packaging, complex internal circuits, and a high probability of failure and crash; the function is relatively solidified, and when learning single-chip computers, only a few The plug-in connection cannot fundamentally understand the matching relationship between software and hardware, which is not conducive to the learning of single-chip microcomputers; the program can only be downloaded through the serial port line. When the distance between the single-chip microcomputer and the computer is far away, downloading is inconvenient, etc.
