需要实现点阵按列依次并且循环显示的效果，可以分析视觉上可以观察到列的变化，则列的扫描频率必定要远远小于行扫描的频率。在程序中，设置行扫描的频率等于前次实验中数码管扫描的频率，设置列扫描的频率为5HZ，即每0.2s显示亮的一列向前推进一列。在程序中，使用16进制计数作为74HC154的输入：分出5hz的频率，并用其计数，将计数值作为74HC154，则其译码产生的输出变化也为5hz，并且实现每列一次选通。由于每行对应的数码管共阳极。直接赋高电平。则可以实现所需要的功能。行扫面则是要实现先依行点亮，再实现列点亮。-Lattice scanning procedures: need to achieve in sequence and cycle according to the dot matrix display effect, can be analyzed visually observed column changes, the scanning frequency of the column must be far less than the line scanning frequency. In the program, set the line scan frequency is equal to the previous experiment in digital scanning frequency, set the column scanning the frequency is 5HZ, each 0.2S display a list of bright forward. In the program, using 16 hexadecimal count as the input of 74HC154: the frequency of 5Hz, and the count, the count of the 74HC154 output, change its decoding generated for the 5Hz, and the realization of each column of a selected through the digital tube. Because each row corresponding to the anode. The high level can be directly assigned. To achieve the required functionality. For scanning is to achieve the first in line to realize the column light, lit. This program is based on the Quartus programming environment, using Veilog language Langu
