Controlling a 14x36 LED Display

Development Boards Arduino
1

Hi,

I wanted to make a 14*36 display, where all of the LEDs will be of the on/ off type. I will use it to display both animations (for which I’ll probably need to control individual LEDs), as well as rolling text. I really want to use a ready made library (for Arduino) for it, rather than coding the entire thing myself. The only chip I’ve found so far is MAX72XX chips, but the libraries for them don’t support a vertical resolution of more than 8 LEDs. I’d appreciate it if someone could help me work around my issue, and recommend a library and/ or chip to do the needful. I open to using any Arduino available. I am also open to using any matrix configuration. for eg - several 7x8 matrices, and so on.

Thanks a tonne,

CB.

You can look at the WS2801 (3 channel). series chips. https://www.sparkfun.com/products/10444 http://www.adafruit.com/datasheets/WS2801.pdf

Or the WS2803 (18 channels). http://www.noodlehed.com/ebay/datasheets/WS2803.pdf

These chips can be daisy chained for more channels.

Also look into multiplexing.

You also have the TLC5940 chips as well.
