I explicitly wrote "But 11x10 characters seen as 11x10 pixels" to inform that each character represents one cell in an array. And each cell can be seen as a pixel in a bitmap. And the 8x8 LED modules can be seen as output devices for bitmaps.
The only issue then is if one character should have one LED. Or a 2x2 LED rectangle. Or a 3x3 LED rectangle. That's where you lose me ... I'd say one has to illuminate the display one word at a time, and not one character at a time. For that I'd use one, two, or three LED's with a diffuser for each word, depending on word length, rather than a multiple of LED's for each character. Aside from increasing the effort and cost considerably, I don't see how multiple LED's per character help anything. Please explain. All just a question of how big you want to make the clock. As a school project, it should be enough with a single LED/character. Creating a fancy design for your living room, it would probably look way better if designed with multiple LED/character. But changing the number of diodes doesn't change the concept, or the complexity. If the concept is to produce words rather than symbols, why go to character-by-character display mode? What's the benefit? RE |
