MCU development training device

ZN-300NS single-chip microcomputer development and training device
1. Overview
ZN-300NS single-chip microcomputer development and training device is based on the teaching textbook "Single-chip Microcomputer Principle and Interface Technology", "Single-chip microcomputer principle and application", "8051 single-chip microcomputer C language program design and example analysis", "Single-chip microcomputer application system and development technology", etc., and specially designed single-chip experimental device. The ZN-300NS single-chip development and training device uses AT89S52 chip, and the peripheral interfaces include digital tube, buttons, 8255, A/D conversion, LCD interface, communication interface and ISP download modules. The experimental modules of the device are independent, and all the experimental interfaces are drawn. The ZN-300NS single-chip microcomputer development training device is suitable for single-chip experimental teaching and also suitable for students' self-study.

①The experimental hanging box, functional modules, and experimental table frame are all made of aluminum alloy at one time, with uniform appearance, beautiful and generous;
②Modular design, strong expansibility, and convenient maintenance. All experimental hanging boxes and power supply function modules adopt detachable and free combination design, which is convenient for expansion and function upgrade; at the same time, it also solves the problem of difficult maintenance of the whole machine. As long as the small hanging box is sent back to the manufacturer, it can be quickly , Solve corresponding problems conveniently.
Part of functional modules:


design dust-proof curtain. When the experimental device is idle, pulling down the dust-proof curtain can extend the service life of the experimental device.
The effect of the whole machine with a dust-proof curtain.
Software description
Single-chip simulation software: It can fully simulate the simulation of the system composed of the single-chip and its peripheral circuits, RS-232 dynamic simulation, C debugger, SPI debugger, keyboard and LCD system simulation Functions; there are various virtual instruments, such as oscilloscopes, logic analyzers, signal generators, etc. It can be combined with keil for program debugging. It is a good helper for learning and development, and has the functions of analog circuit simulation and digital circuit simulation.
2. Main technology and function
