DataPix: a programmable LED matrix ticker

Field notes

DataPix separates display design from firmware coding: its interface lets users map JSON fields onto a 64×32 grid, then combine those values with text, sprites, effects, and animations. The page lists up to 30 rotating views, eight custom API sources, six elements per view, and imports for images and GIFs. Its browser demo uses simulated data, while the described physical unit runs the interface over a local network on an ESP32-S3 with 16 MB of flash and 8 MB of PSRAM.
