数电实验箱的数码管为共阳动态扫描数码管。针对该数码管采用动态扫描模式。扫描频率为10KHZ。数码管按照习惯从左到右为高低位千位道个位。
模块内包含三个进程：一为计数值读取及译码，二为小数点状态读取及译码，三将译码后的数据从端口输出并配合位选信号实现动态扫描。-Several electrical boxes digital tube experiment for a total dynamic scanning digital tube Yang. Digital tube against the dynamic scanning mode. Scanning frequency 10KHZ. Digital tube from left to right in accordance with the customary place for the level of 1000 Road a bit. Module consists of three processes: one for reading and decoding of values, two for the state of reading and decoding a decimal point, the three will be after decoding the data from the port and in line with the digital output signal to achieve dynamic scanning election.
