利用SST89E516实现24LED跑灯，其中运用的，74LS161三片，原理图不知道弄那去了。找到的时候再传上来。-24LED use to achieve SST89E516 running lights, which use, 74LS161 3, schematic diagram do not know get it going. Send up to find the time.

用74ls161编的数字电路时钟图.方便刚接触单片机的人学习-Series of digital circuits with 74ls161 clock map

使用51单片机，以及74LS161芯片，对脉冲进行计数，提供详细的相关芯片资料，仿真文件，可直接观看运行效果。 -51 single use, and 74LS161 chips, the pulse count, providing detailed information related to the chip, the simulation files can be run directly watch the effect.

采用8位右移寄存器74ls164实现8个彩灯的向右移动，从它的右移输入端输入四种码，来实现它的四种花样，根据四种花样确定四种码，可通过模16计数器74ls161的输出端接与门74ls08和非门74ls04产生。-8-bit right shift register 74ls164 move to the right of the eight lanterns, it s shifted to the right input of the input four kinds of code, to
