一、内容分析本课题选自《电子综合技术》课程,项目八——简易函数信号发生器的制作中的任务二。移位寄存器是一种具有移位功能的寄存器,在寄存器中所存的代码能够在移位脉冲的作用下依次左移或右移。它的应用很广,可构成移位寄存器型计数器;顺序脉冲发生器;串行累加器等等。本节课,利用集成移位寄存器4015对发光二极管的亮灭进行控制,产生彩灯变化的显示效应,从而使学生可以形象的观察到移位寄存器的工作方式。
First, the content analysis This topic is selected from the “electronic integrated technology” course, project eight - simple function signal generator in the production of task two. A shift register is a shift register. The code stored in the register can be shifted to the left or right by the shift pulse. It is widely used, can form a shift register type counter; sequential pulse generator; serial accumulator and so on. This lesson, the use of integrated shift register 4015 on the light-emitting diode is off control, resulting lantern changes display, so that students can observe the image of the shift register work.
