Hello,
Though I'm a newbie at VHDL I managed to write a keyboard interface ( though it is only unidirectional, it is a success) for my board and am correctly displaying the letters on SSD. Now I am thinking of going one step further, that is to say I want to extend the borders of SSD. But I can not think of any simple way to do so, I need some advice here. I don't like using already written code blocks, so please, even if you share any, do explain it because I will need the knowledge. Primarily I need the idea, so if you have any sources about "scrolling text on Seven Segment Display", I will be glad. I'm writing in VHDL by the way.
All I can think of is, I will need an enable signal to activate each SSD up to 4 letters. But then things start to mess up, when I press the next button, for example the second S letter in BASY"S", the SSD should show ASYS. Then, after accomplishing this, I am thinking of scrolling the text from right to left. Any help is appreciated already! Thank you!
P.S. I can include my codes in the next message if someone wants to see them to help me.
