8051-or-AVR-based multi-core singlechip teaching experimental platform

Abstract

The invention discloses an 8051-or-AVR-based multi-core singlechip teaching experimental platform, and belongs to the field of embedded computers. The hardware of the platform comprises a mainboard, and two circuit boards of an AVR adapter plate; an 8051 singlechip adopts AT89S52; an AVR singlechip adopts ATMEGA32; AT89S52 can be directly inserted into the mainboard for work and at the moment, the platform works in an 8051 mode; ATMEGA32 can be inserted into the mainboard for work through the AVR adapter plate, the AVR adapter plate transforms ATMEGA32 pin encapsulation form into AT89S52 pin encapsulation form and at the moment, the platform works in an AVR mode. The mainboard consists of a power supply, a basic functional part and an interface communication part. A platform software system is divided into two layers, namely a driving layer and an application layer; the driving layer finishes the encapsulation of hardware resources of two singlechips; the application layer is a comprehensive demonstration program having 14 experiments, runs with support of the driving layer, and is irrelevant with hardware.

Description

technical field [0001] The invention belongs to the field of embedded computers and relates to an 8051 / AVR-based multi-core microcontroller teaching experiment platform. Background technique [0002] In the current single-chip microcomputer course teaching in colleges and universities, there are problems such as repeated purchase of experimental equipment, and the disconnection between equipment functions and social needs. On the one hand, single-chip microcomputers have a wide range of applications, and different types of single-chip microcomputers are suitable for different occasions. There are large differences between these single-chip microcomputers. In order to enable students to adapt to different needs of society, colleges and universities often need to purchase multiple types of single-chip microcomputer equipment. There are overlapping functions, which will inevitably cause a certain degree of waste. On the other hand, with the rapid development of embedded comput...
