Application: This code uses W78E516 to drive LED dot matrix scroll display.
Hardware: W78E516
Usually we want to display a paragraph of text on the LED dot matrix screen, but this text content is too much to be displayed on the LED screen. In this case, the LED screen needs to be able to scroll through the text.
This sample code is mainly to demonstrate how to scroll text on an 8×8 LED dot matrix screen. We want to display text on the LED dot matrix screen, usually by dynamic scanning to drive the LED dot matrix.
This sample code uses the column scan method to drive the LED dot matrix. From the first column on the far left, it lights up to the eighth column, and the text scrolls from right to left.
