Big Adafruit GFX Demo for NeoMatrix #9

Closed marcmerlin closed 7 years ago

marcmerlin commented 7 years ago

I spent quite a bit of time writing an Adafruit GFX demo for Neomatrix, and was able to port it trivially to RGB-matrix-Panel. Please see this video of the demo https://www.youtube.com/watch?v=9yGZLtewmfI , jump to 3:25 to see the demo on the RGB-matrix-Panel

This page describes the demo in more details, with screenshots: http://marc.merlins.org/perso/arduino/post_2017-04-24_Adafruit-GFX-on-NeoMatrix-and-RGB-Matrix-Panel-Demo.html

The demo is able to adjust to the display size and do things relevant to each size: image

This was tested on:

This demo depends on https://github.com/adafruit/Adafruit-GFX-Library/pull/39 which is the only way to display multicolor pixmaps in a backend independent way.

By the way, I need to credit @ladyada for some of the code that originally came from Adafruit_LED_Backpack/examples/bicolor8x8 but was heavily modified/improved/supplemented over the years. I just felt it was a shame that your newer matrix libraries did not provide such a demo, so that's why I took it, heavily improved it, and I'm now contributing it back.

By the way, @ladyada while this wasn't the point of this PR, if you'd like to take my video/and or blog post to put on your G+ feed as a demo of what can be done with your library code and some of your hardware ( I made it work on your RGB panel too: https://github.com/adafruit/RGB-matrix-Panel/pull/32 ), feel free. Cheers.

Thanks @PaintYourDragon for your upstream merge in GFX lib. I've now updated this demo to work with its interface and re-tested it. Hopefully you'll like it as a more featureful example for this lib (and example for those new methods in GFX)

Howdy again, assuming you don't have time to review this, since it doesn't change any other code, do you mind integrating it as is?

marcmerlin commented 7 years ago

Hi @PaintYourDragon are you the person who can help with this standalone demo merge, or could you recommend someone else?

marcmerlin commented 7 years ago

@PaintYourDragon or @ladyada thanks for merging https://github.com/adafruit/RGB-matrix-Panel/pull/32 . This patch is exactly the same demo for neomatrix. Would you be able to merge it here too, especially since more people are probably using neomatrix nowadays?

@PaintYourDragon @ladyada howdy. Happy 4th! sorry to bug you again, I just had another person ask about this demo and I had to point them to the unmerged patch. I know you maintain way too many trees and have limited time to review patches, but given that this doesn't touch anything existing and adds a much better demo than anything included with the library, could you do a merge like you did on RGB-matrix-panel?

Thanks a mil!
