I’m hoping this is just a matter of something being set wrong. I have 1922 LEDs I am mapping on to a sphere. There are 41 rows and the widest rows have 72 LEDs. I used this site to create the LED map WLED-Ledmap.json-Generator This is the map file it created w…

its perfectly stable. did you install the version for WROVER? otherwise it will bootloop.

FYI: WROVER rev.1 needs special build with workaround for hardware bug when accessing PSRAM. PSRAM is no longer needed for large ledmaps in 0.16.

I installed it via the install.wled.me site. It doesn’t give me an option to choose specific hardware. Should I be installing from somewhere else?

Oh good! I’ll try on one of my WROOM boards. I had only been using WROVER boards because of the PSRAM.

in 0.16, WROOM now works quite well up to 3000 LEDs, probably a few more if they are virtual. but 64x64 is pushing the limits without PSRAM.

So it did install correctly on the WROOM, and there seems to be plenty of memory. Only 131kb of 983kb available. However, it’s not failing in a different way. It’s just not loading the LED map at all. I have tried 2 different builds of the LED map from 2 different map builders. Same result. …

With correct ledmap, you don’t need 2D set-up if you use “ledmap.json” file name. After uploading ledmap, you need to reboot. Additional ledmaps will ignore dimensions (will use dimensions from “ledmap.json”). Your file “ledmap (1).json” is not a “valid” JSON file as far as WLED goes. Line breaks…

Thank You! I will work on that today. Was “ledmap (2).json” in the correct format? 1 was made using WLED-Ledmap.json-Generator 2 was made using SRGB Component Builder

Wiped the board and installed the debug version. Used the ledmap (2).json file. Renaming it to just ledmap.json before uploading it. Did not do anything in the 2D matrix page. Rebooted after uploading. Still no map applied, just a 72x41 rectangle. Here is the debug dump https://drive.google.com/fil…
