greetings everyone,
this is my problem :

I need to make an 8x8 led matrix display with my 8052, (or bigger, as RAM-size could allow it) but I want it to operate like it does in computers: it should have his own video-ram where I can write to, and the display should have it's own hardware to refresh itself so the µC doesn't have to spend time on that asset. I thought of a system but I can't come up with possible fast solutions...

I was thinking of implementing the "video-ram" as an external chip, which is read continually by other external hardware to display it's contents on the led-matrix, but I'm struggling on finding a fast solution to adjust the videoram's contents...

Should I work interrupt driven and write 1 byte at a time? Or should I work with some sort of DMA and write a whole block of data at a time?

Are there any sites, info or chips out there on implementing a thing like that?

Lot's of thanks in advance,
Jeffrey
