I bought a 16X64 LED lattice screen to learn microcontroller, now encountered a problem is how to realize the LED lattice left scrolling LED dot matrix is Chinese characters, I used 8 74HC595 as the column driver, a 74HC154 line scan, the heroes who have no reference to the younger program reference, is used the compilation of the
I wrote one myself, but not 595, but the latch, and the rest of it is exactly the same, the assembler wrote, the principle HI me, and I still have work, so if you're not busy, you can learn from each other
As the left only a scraper with 154 implementation, your hardware does not allow you to move around, can move up or down, unless shuabing. Why use 154, and then 2, 595 not good
If there is a program that displays a "static" screen, you can write a program called "left" scrolling.
You can go to a professional LED website to have a look
