This question already has an answer here:
I have a matrix of 32-by-32 LEDs that I need to control using a driver. The largest driver that I found was a 16-by-16 driver by Linear Technology, and there is no driver that goes higher than 16-by-16.
Here are the requirements:
- monochrome LEDs (color not needed)
- LEDs just need to go on or off, no greyscale required
- pixels cannot be addressed individually, need to use column/row method
Is it possible to use two or more drivers together for this purpose? How? If not, what could be the alternative?
