Anyone who has purchased any materials on the principles and applications of the 818 microcontroller can obtain the monthly self-test papers and answers for free.
The September exam paper has a full score of 150 points, covering six major question types: fill-in-the-blank, multiple choice, hardware circuits, short answer, program design, and system design, comprehensively assessing students’ mastery and application abilities of core knowledge of the MCS-51 microcontroller.The content of the questions deeply integrates theory and practice, with a focus on key points. The fill-in-the-blank and multiple-choice questions emphasize basic concepts such as CPU architecture, interrupt systems, memory expansion, and interface technology. The hardware circuit questions require designing system expansions and calculating address ranges, testing hardware design skills. The short answer questions delve into core mechanisms such as interrupt priority control and the three-bus structure. The program design questions account for the largest proportion (40 points), requiring the completion of data operations, string comparisons, and complex timer application programming in assembly language, emphasizing practical abilities in software and hardware integration. The final system design question integrates address decoding of the 8155 interface chip, timer interrupt programming, and I/O control, representing a typical microcontroller system development scenario.Overall, this exam paper is of high difficulty, requiring candidates not only to memorize knowledge points but also to possess solid programming, hardware analysis, and system integration skills.
