Michael, I would love to appreciate your work; you have created a beautiful library. I'm working on a project where I will be loading frame by frame animations from a SD card and displaying on the LED matrix. Michael is there a way I can load layouts too from SD card, by creating a layout file which will specify the layout topology, with width and height as well. This will make things easier as I will only need to edit the layout text file in the SD card, instead of re-compiling and flashing esp8266 again to change the layout. Thank you. Hope to hear from you soon.
