Description

technical field [0001] The present invention relates to a single-chip microcomputer teaching, in particular to a multifunctional embedded single-chip microcomputer teaching experiment device based on a programmable logic device; in particular to a single-chip simulation, ispLSI programming, and integrated functional module units commonly used in single-chip systems and Teaching experiment system with various communication interfaces. Background technique [0002] Microcontroller MCU is developed on the basis of the concept of single-chip computer (commonly known as single-chip microcomputer in China). It integrates the microprocessor and its peripheral circuits, peripheral interfaces, etc. into the same chip, and can be independent without the support of other auxiliary circuits. An integrated circuit that completes calculation, amplification, processing, etc., has excellent peripheral interface control functions, and is easy to form a variety of industrial control, adaptive...

AI Technical Summary

Problems solved by technology

The production of a formal experimental circuit board needs to start from the design of the schematic diagram, the procurement of components (retail is difficult to buy and expensive), the design of the PCB and the customization, which will consume a certain amount of manpower and material resources. The development tool to be used is the emulator. The price of a professional emulator is more than 1500, and there is often a certain deviation between the results obtained by the simulation and the results of running on the actual target system.

In addition, the emulator cannot write memory chips, and programmers have to be purchased to write memory chips. These tools are not only expensive, but the relationship between various development tools is difficult for students who are learning MCU for the first time. Due to the limited learning hours, many students Have not fully grasped the relationship and usage of these tools by the end of the course

Another point is that the traditional MCU teaching experiment development tools often need to plug and unplug the emulation head, plug and unplug the CPU chip, and write the memory chip. Not only is the process cumbersome, but it is easy to damage the development tool, target system and integrated circuit chip
