编号: 嵌入式系统实训 (论文)说明书题 目: 基于嵌入式 ARM 步进电机的驱动 院 (系): 应用科技学院 专 业: 电子信息工程 学生姓名: 学 号: 指导老师: 2011 年 01 月 19 日摘 要随着 ARM 在各个领域的广泛应用,许多用 ARM 作为控制的步进电机驱动器系统也应运产生,本设计介绍一种有 ARM LPC2132 的编程控制基于 L293 电机驱动芯片的步进电机驱动系统。本系统可以通过控制板上面的 7 个按键进行功能设置,该系统具有启动、停止、正转、反转、速度调节、细分步和速度显示功能。本设计具有价格低廉、性能稳定、操作方便且修改灵活等特点。由于本系统是由 L293 驱动的步进电机系统,通用性强,可以用到各个需要用到步进电机的场合使用。主控芯片采纳 ARM LPC2132,按键操作使用简洁,LED 数码管速度显示,安装方便。解决了一些步进电机驱动系统中没有速度显示的问题,适合在各种场合的步进电机驱动器械中使用,它电路简单易懂,调试方便,功能齐全,系统稳定可靠,是一款很有用的步进电机驱动电路。关键词: ARM LPC2132;LED 数码管显示;细分步;L293 驱动AbstractAs ARM's widely used in various fields, many with ARM as the control of the game scoring device timing system should also shipped produce, the design introduces a kind of ARM LPC2132 programming control L293 dots on the display of the basketball game time than scoring system. The system can control panel 7 above the buttons feature set, the system has set the schedule time, schedule time to be suspended, the score addition and subtraction, the extra time and other functions. This design has low price, stable performance, easy to operate and modify flexible. As the system is L293 large dot matrix display as the display module can be directly applied to all types of schools and small groups as time basketball scoring race. Master chip ARM LPC2132, using the simple button operation, LED display, easy to install. Basketball counter solve installation problems, saving the wire, suitable for use...
