I am trying to run the LEDMatrix example 2. The one with the flags. Only line 0 of my matrix lights up.

Please provide more information! Is this a matrix you bought or made yourself? What’s the size? How is it wired, S or Z configuration?

And can you please share your code? Put it on http://gist.github.com and share the link.

Its a matrix I made and it works good on other fast led examples. I was wanting to see the flags. It is a built-in example. Ws2811 , 54x7, horizontal_zigzag_matrix, brightness 32, pin 7. Is there more than one version of LEDMatrix?

SOLVED. updated LEDMatrix from ver3 to ver4.
