15x7 Charlieplex Featherwing matrix working on Uno Board

Hello all,

I am a complete Arduino beginner and maybe trying something a bit too difficult too fast, But perseverance will prevail.

I have bought an UNO along with a featherwing LED Matrix. The board has a demo that can be downloaded but I am having difficulty getting it to work. (See attachment)

I can only assume its the way these libraries work and i’ve not copied the folders across properly?

Any help on this would be greatly appreciated.

Regards,

and never ever post a screen shot of code. How can we replicate your code on our machines to find out what is wrong?

Featherwings operate at 3.3V but the Uno operates at 5V so these are not compatible. Use a Feather CPU board with the featherwing board.

And that effects compiling code how?
