What are the main contents of the National Electronics Competition Microcontroller Design and Development?

The content of the National Electronic Professional Talent Design and Skills Competition Microcontroller is: (For details, please see the official website of the electronic competition: c.org/, I don’t know about the others) Contestants must complete the work according to the allotment within the specified time Complete the following operations: 1. Hardware circuit design. According to the requirements of the competition topic, use the given materials to design a circuit schematic diagram using PROTEL software (Protel 99SE or Protel 2004 DXP is recommended). 2. Circuit board welding and assembly. According to the schematic diagram, electronic components and functional parts are welded on the circuit board provided by the venue and assembled into an actual microcontroller product. 3. Product hardware circuit debugging. According to the product function and technical index requirements stipulated in the competition title, debug the assembled microcontroller product and record the debugging results as required. 4. Write programs and coordinate software and hardware. Write a program according to the competition topic requirements and the microcontroller product function manual, and download the complete debugged program to the chip online. Remarks: (1) The competition microcontroller chip uses AT89S52, the software debugging environment is Keil C (Keil C51 V802a is recommended), and the online download software is IspPgm (IspPgm30a is recommended). (2) The programming language can be assembly language or C language.
