This is the last chapter about led message boards. The highest point of their evolution (I mean, this particular kind, of course 🙂 ), guided by me 🙂 At the end we concluded that the most usable size for our message boards is 7x64px. We had been experimenting with different matrix sizes and different LED […]

The simplest 8×16 LED message board based on Microchip PIC 16F84. The basics of dynamic image rendering.
My fun with LED message boards started in the very end of 2004 and ended in August 2005. By the August 2005 I had created some simple LED message boards (8×64 and 8×128), which are usually called here “the running string”, and had placed myself to stalemate. For my boards I used Assembler language and […]
