Turning four panels into one 128x128 display, then fixing the WLED docs
I connected four 64x64 panels to my WLED matrix to make one 128x128 display. Getting WLED to drive it as a single square took some figuring out, since the docs hadn't caught up with the grid feature yet. Here's the actual setup, why the 180 degree flip of the bottom row needs no software setting, and the docs update I sent back.
