移位寄存器控制的流水灯设计

Design of Cycle Lamp Controlled by Shift Register

阐述由555集成电路构成多谐振荡器产生时钟脉冲,作为流水灯控制电路的脉冲输入信号,移位控制器用74HC164集成电路控制流水灯,74HC164是8位边沿触发式移位寄存器。设计移位寄存器控制流水灯(灯从全亮,到依次全灭)手动复零电路,然后设计了移位寄存器控制流水灯(灯从全亮,到依次全灭)自动复零电路,在自动复位的流水灯控制电路中,需要使用CD4069反相器集成电路。设计8个灯依次灭和依次亮的右移自动循环控制电路,以及流水灯一亮一灭闪烁右移自动循环的控制电路。

This paper describes that the multivibrator composed of 555 integrated circuit generates clock pulse as the pulse input signal of the water lamp control circuit.The shift controller uses 74HC164 integrated circuit to control the water lamp.74HC164 is an 8-bit edge triggered shift register.It designs the manual reset circuit of the shift register controlling the flow lamp(from full on to full off in sequence),and then designs the automatic reset circuit of the shift register controlling the flow lamp(from full on to full off in sequence).In the automatic reset flow lamp control circuit,it needs to use the CD4069 Inverter IC.It designs a right shift automatic circulation control circuit in which 8 lights are turned off and on in turn,and a water flow light is turned on and off and flickers right shift automatic circulation control circuit.
