Hello everyone,

I would like to know how I can connect more LED arrays (buy from adafruit)
so join in a single screen.
I tried searching the internet and I found only this tutorial:
https://learn.adafruit.com/animating-multiple-led-backpacks/software

Can anyone give me some help or make available in your code?

Thanks in advance
Stefano

It would help if you supplied links to the products your talking about. You might be lucky and the I2C backpack will allow address changing or you may not and need to use other means.
Don't PM me for help as I will ignore it.

The other problem is the memory it takes to store the image before transferring it to the display. A UNO will not have much free SRAM so a mega or a due will be needed. Or an external SRAM chip.
