Cuw posted:Here is my current plan, I am going to use a ATMEGA16 to control a big ole grid of LEDs. My plan was to make an addressing scheme similar to how RAM is access with a column address and a row address and divide the memory into that, maybe have the column be ground and the row's be hot. When the address is hit the LED will then turn on! Voila easy as pie. The issue with this is I need tons and tons of address lines, unless I multiplex the lines but then speed becomes an issue. How would be the best way of doing this? Am I completely over complicating this because if I am please tell me. Usually, matrix multiplexing is the way to go when controlling an LED array. With an ATMEGA16, speed shouldn't be a problem at all. How big is your LED array?

ante posted:Ok, what are these called, and where can I get/make a custom one? Those are called FFC (Flat Flex Cable). They are really hard to get in small quantities. If you're a hobbyist, forget about getting a custom one. I needed to replace a broken FFC in a barcode scanner some time ago and got it from some guy who was selling them on eBay.
