So I picked up a TFT touch screen with SD card slot. After building a basic GUI, I’m back to figuring out interesting patterns to display. 7x32 is really tough to get good looking bitmaps going - and it doesn’t help that each LED strip has to be about 1/4" away from the next so I can look through them.
I have 2 animations that are basically scrolling bitmaps, so those will probably be offloaded to the SD card. Then I have a “fake” spectrum analyzer - it’s using the right math, but it’s reading an empty analog pin.
Finally, I had a plasma fractal. it looks nice, but it’s incredibly slow due to all the floating point math. I removed it because it was just too slow.
As you can see from the video, the scrolling text doesn’t work very well due to the gaps.
I’m currently trying to come up with a more “accurate” Matrix effect. I tried a game of life, but it just looked chaotic, and not good.
I figure since I have a Mega 2560 for this project now, I might as well load it to the gills with effects. Suggestions welcome! I still have to implement the SD card features, but that shouldn’t be too bad.
