具体的硬件结构,大家可以看 WS 系列产品的原理图 * 利用AT89S51单片机来制作一个手动计数器，在AT89S51单片机的P3.3管脚接一个轻触开关， * 作为手动计数的按钮. 数码管驱动采用动态扫描方式用单片机的P0.0－P0.7驱动数码管的段码， * P1.3 控制个位数码管的共阳极公共端，P1.2 控制十位数码管的共阳极公共端 * 通过按一下P3.3按键,数码管做 1 的累加, 实现00~99的计数功能,当计到99时又从00开始. * 大家可自行修改程序,扩展到0000~9999的计数范围-Specific hardware architecture, we can look WS schematic family of products using AT89S51* Single-chip to produce a manual counter, in the P3.3 pin MCU AT89S51 by one touch switch,* as a manual count of button. nixie tube driven by dynamic scanning with MCU P0.0-P0.7 driver code segment digital tube,* P1.3 control bit digital tube anode of a total public client, P1.2 control of 10 digital total anode tube through public client* P3.3 click buttons, a digital pipe to do one of the cumulative, realize 00 ~ 99 count function, when the total to 99 from 00 the beginning of time.* everyone can modify the program, extended to 0000 range of ~ 9999 count
