LED dot matrix with single-chip microcomputer is how to control?
In principle, and digital control is the same method of control, a digital tube is equivalent to a row of 8 lights
In simple terms, the row remains unchanged. The column moves to the left, for example, the line above remains 01111111, and the next row becomes 01111111, which makes the first row of the line light up. Then, in the left shift, the line is not changed, the original number is how much; and the column, each time the use of "left shift sign", "left shift", it has reached the "left shift" display effect.
To put it simply, the LED dot array requires two rows of 8 bits, one for the line, one for the column, for example 0 is the selected meaning, then the line is 01111111, and the column is 1011111, then the first row of the second column lights.
