"乒乓球发球机控制器软件设计与硬件电路实现"

he hardware circuit with the core of 8-bit single-chip microcomputer STC89C51 and the relevant software programming. It realizes the function of changing the serving speed, serving height, and angle to meet the different technical needs of players, and also sets the random serving mode to achieve the random variation of the landing point. The software design of this project adopts the method of the main function calling the subroutines of various states, and completes the functions of key control, LCD display, and motor speed regulation. Together with the hardware design of our group, we completed the design of the single-chip microcomputer peripheral hardware circuit, including the motor drive module, keyboard module, and LCD display module. Finally, based on the analysis of the hardware circuit and the debugging of the software modules, we conducted online debugging, conducted software and hardware testing of various modules, effectively combined the two, and completed the overall control of the system. Keywords: table tennis serving machine, controller, serving mode, single-chip microcomputer. 摘要，关键词以及全文内容介绍了一种乒乓球发球机控制器，该控制器由硬件电路和软件编程组成，实现了改变发球速度、发球高度和角度以及随机发球模式的功能。硬件电路包括了驱动模块、键盘模块和液晶显示模块，通过软硬件检测和联机调试将两者结合起来，完成了系统的整体控制。本文的设计旨在满足玩家不同的乒乓球训练需求，为乒乓球爱好者提供了一种方便的训练工具。
