Anyone have suggestions on how to map this? There will be two of these connected together to form a crown. Leds on the purple dots. 37 on each section. I’ll probably just end up doing sparkle stuff anyway, but was looking for the best way.
I am also interested in this. Im starting up a few new projects and am curious how others here are mapping their complex pieces. I have not worked with large amounts of pixels yet so this has not been much of an issue yet.
I’d go with an irregular XY map. There’s some techniques discussed in the comments here: https://plus.google.com/+JasonCoon1/posts/PsFjSyFbf2e
nice work! thank you for the link. One of my new projects is going to be a sign. I will be back lighting the letters with a bunch of pixels so it will be a great opportunity to work on understanding and implementing the XY map. Do you happen to have any other resources?
If you chain the leds in a zig-zag line the easy mapping i showed here should work fine: https://plus.google.com/115124694226931502095/posts/eS1Wv3Vycx9
Thanks for the link and example code Stefan. I will play around with that later this weekend.
ooooo I just found the xy matrix example code
