摘要
为了提高单片机实践教学的效果和学生的综合设计能力,本文设计了一种以STC89C52单片机为核心的函数信号发生器实验.该实验主要采用Altium Designer 19完成原理图和PCB印制电路板的设计,并可以利用单片机系统配合D/A转换芯片产生三种以上的波形输出.通过该实验,可以帮助学生理解D/A转换原理及应用,掌握单片机应用系统软硬件的设计和开发,并有效地培养学生的工程实践能力和创新能力.
In order to improve the effect of practical teaching and student’s comprehensive design ability,experiment of function signal generator based on STC89C52 single chip microcomputer was designed In the experiment,Altium designer 19 is used to complete the design of schematic diagram and PCB printed circuit board.More than three kinds of waveform output are generated by using the single chip microcomputer system and D/A conversion chip.This experiment can help students understand the principle and application of D/A conversion and learn to the design and develop software and hardware of single chip microcomputer application system,and effectively cultivate student’s practical ability and innovation ability in engineering.
