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
