本实验中共接入了8个共阳八段数码管(数码管阳极连在一起),演示数码管中的某一段点亮只需在对应的位置写入“0”即可。在这里74HC595实现了数据串并转换的功能,试验中用到的两片74HC595分别用于控制八个数码管的位选和其中每
个数码管的段选。-The experimental access the 8 Common Yang eight digital tube (digital tube anode together), a certain period in the demo digital tube lit can just write " 0" in the corresponding position. Two 74HC595 74HC595 to achieve a data string and conversion functions used in the trial are used to control the election of eight-bit digital control and each digital tube segment selector.
