So glad I found this product! My son and I have been working on something very similar as an art project for my wife for Christmas. Unfortunately, we’re in over our heads. So I think we’ll just adjust our plans to be able to take advantages of some of the awesomeness here!
What I’ve got so far: I’ve already got a Teensy 3.6 and a slug of ws2812b lights, and we already build the matrix frame and dividers for a 20×20 grid.
Assuming I use the v2 code, a couple of questions:
1. Do I need to rebuild the grid to 16×16 to use your code, or can I just modify the bmp files to make them 20×20 and modify the settings in the code to reflect the 20×20 grid? (We’re not coders, just learning). I can rebuild the matrix if necessary.
2. If I buy your Wi-Fi adapter, will I be able to do the IFTTT stuff with the other hardware I have? I saw on another post something about you using a different LED in your v2 build – are the ws2812s a problem for me? Any other hardware I need?
Thanks again for this great resource and in advance for any help! I think I’m going to buy one of your frames for my office – It’s a much more elegant physical design than ours!November 28, 2016 at 7:49 pm #3343Jeremy WilliamsKeymaster
1) I haven’t tested anything other than 16×16, and at least one function is hard coded for that (getIndex). Actually, now that I think about it awhile back I did make a 32×32 version and I don’t think I changed more than getIndex… anyway, yes, it will require some small code changes.
2) As you know, V2 uses APA102 LEDs. These are not compatible with NeoPixels (WS2812). You can use the V2 source code but you’ll need to change the way the LEDs are initialized. It’s a simple change that others have done. However, this will mean the IR Remote control is not going to work and you’ll need to use physical buttons.
As for the Wi-Fi Adapter, I haven’t tried it with WS2812 but I imagine it would work with the same code change. The problem is the Photon development environment isn’t as straight forward as the Teensy/Arduino one. I’d stick with Teensy if I were you.November 29, 2016 at 8:28 pm #3353
Thanks Jeremy. I see what you mean about photon dev. I’ve been messing with it for an hour and I still haven’t been able to read the .bin – no matter what I select it just appears as gibberish. I worked through a few tutorials and programming seems relatively straightforward. I’d like to try to make photon work before I give up – is there an easy trick to editing the .bin that I’m missing?

Ahh, I realize already how stupid I am. All that’s in the file is the compiled code. If the Wi-Fi Adapter source code is not available that’s fine – was just hoping to play with it!
Thanks again, Jeremy.November 29, 2016 at 9:38 pm #3356Jeremy WilliamsKeymaster
Sorry, Photon source code is not available yet.
