I am looking for suggestions on interfacing a ATMega8515L or theAT90S8515 device to a 8X8 LED display.
I have one of LED display's laying around and would like to make a scrolling clock display.
Searching the Internet, I found many projects that use the Max 7219 device. I did not want to use that chip. However, I am thinking that I can use a ULN2003 to control the cathode side as a row driver and then send the 8 bits per row from a selected
8 bit port. This means that each full character must have 8 each 8 bit patterns associated with the character.
I don’t see any advantage in using a X/Y coordinate approach but I am not sure, is that even a way to consider?
Looking for suggestions…..
