A modularized single-chip integrated development experiment box and its application

Abstract

The invention relates to a comprehensive development experimental box for a modular single-chip microcomputer and an application thereof. According to the comprehensive development experimental box, protruding elastic pieces are arranged in grooves of a primary circuit board, the edges of auxiliary circuit boards are provided with gaps corresponding to the protruding elastic pieces, the auxiliary circuit boards are embedded in the grooves, and the protruding elastic pieces are clamped into the gaps to be connected with a metal sheet. The comprehensive development experimental box overcomes the defect that because a traditional comprehensive development experimental box for a single-chip microcomputer is small, when installed, circuit boards are difficult to align and effectively solves the problem that a plug and a socket are prone to damage due to repeated plugging and unplugging.

Description

technical field [0001] The invention relates to a modular single-chip comprehensive development experiment box and its application, belonging to the technical field of teaching instruments. Background technique [0002] Single-chip microcomputer is an integrated circuit chip, which uses VLSI technology to integrate a central processing unit CPU with data processing capabilities, a random access memory RAM, a read-only memory ROM, a variety of I / O ports, an interrupt system and a timer / timer A small but complete microcomputer system is formed by integrating electronic components such as display drive circuits, pulse width modulation circuits, analog multiplexers, A / D converters, etc., into a silicon chip. Nowadays, single-chip microcomputers have penetrated into all areas of our lives and play an irreplaceable role, so it is very important to learn and master the knowledge of single-chip microcomputers, and doing single-chip microcomputer experiments is a particularly importa...

AI Technical Summary

Problems solved by technology

[0003] For the previous single-chip experiment box, most of them adopt an integrated design. In the experiment, the experimenter needs to perform various operations on a whole large circuit board, and needs to connect a large number of external wires. It is easy to make mistakes in wiring, and the operation is also relatively complicated. It is helpful for the experimenter to understand the working mode of the single-chip microcomputer and the control communication between each module; moreover, due to the limited IO port of the single-chip microcomputer, the experimental content that can be involved on the same circuit board is very limited; in addition, the traditional single-chip microcomputer experiment box needs an external It's inconvenient when you're showing

For the above-mentioned shortcomings of the single-chip microcomputer test box, the existing solution is to modularize the single-chip microcomputer and install it on the total module of the single-chip microcomputer detachably, thereby improving the flexibility of using the single-chip microcomputer test box; however, most of the single-chip microcomputer test boxes of this design Banana plugs or horn plugs are used to connect with the main module of the single-chip microcomputer. It is inconvenient to connect. Plugged into another board, hard to align
