Posted at 2021-04-13 by @gfwilliams Great! It's good that you spotted that! I've actually had this with those panels before (albeit only 4 of them!) - when the LEDs are full intensity they draw a whole bunch of power. You could actually run the panels off of 5v I believe (but check just in case!) which should reduce the stress on the 3.3v regulator. I guess you spotted this as it seems this was your post previously, but for anyone else looking it should be possible to modify the code posted at http://forum.espruino.com/conversations/874/#15844271 to allow you to use a Graphics instance on these panels |

I connect 2 matrix led( 32 x 16 ) into one big (64 x 16).

It's rendering order :
and upload code below:
the first time I upload , it shows right.
when i do multiple times , it shows wrong.
I test it by:
it seem has some issues:
disp.displayTest(true);

disp.displayTest(false);

What's wrong with it ?
