Hello. I decided to make a video lesson on the character LCD indicator in support of novice microcontroller programmers. As they say, it's better to see once than hear a hundred times.
Beginners mostly use ready-made libraries for working with the lcd-indicator and, of course, have no idea how the microcontroller-indicator exchange protocol is organized. But, knowing this, you can create a program yourself not worse, if not better. In this video tutorial, I tried to explain the basics of working with the ld indicator in detail and clearly. Since I always write my own programs for the microcontroller myself and try not to use ready-made libraries, I support those who also seek to deal with external peripheral devices themselves and create their own programs for the microcontroller. I hope that this video tutorial will be useful for beginners, and some of them will get something new for themselves.
