Is there any code for converting pictures or a gif to an LED matrix using just FastLED?
I always just bitmap my images with mathlab. I’ve been out of the fasted scene for over a year now but don’t ever recall seeing that tool. Thought it would be super useful. Anymore I just process the image on the fly and store the full image in memory of some sort I.e SD card or flash
@Larry1 I just recently started working with matlab, so it is pretty new to me. Could you possible expand on converting and having fastled read it.
Unless your working with very limited space it’s really extra work do pre-process the images. I can bitmap a bmp or jpg from flash with just a teensy and display a 1028 pixel RGB matrix. I have done it will far less like the 328 (mini pro)
You can message me on hangouts I’d never happy to help if you can catch me online
I wrote my own converter to process images for my POV project. I wrote it as an external program, so it’s not something done on the fly so to speak. I pre-process images into files that contain the RGB data that my Arduino program then reads in (from an SD card). And because I wrote it, I can read it most image formats and output what I need.
There are some other pieces to it, such as scaling it to the size of the POV unit, adjusting transparency, flattening the image, etc., etc.
@Larry1 my project is fairly large, 1500+ leds with the last visible being 1311. I have never used hangouts but if I see you on there I will start a conversation.
@Ashley_M_Kirchner_No I looked through your old posts and couldn’t find your project. I am only wanting to do one or two images, I have other color patterns that I will be using also.
That’s because I never posted the C++ code. It lives on my server at home.
