The ESP32-P4 can now display interactive OpenStreetMap tiles right on its screen, with pan, zoom, and a PSRAM tile cache for smooth movement. Drop markers at any coordinates — colored dots, icons, or your own images — and draw tracks to show routes and paths. MAP_INIT creates the map, MAP_SOURCE points it at the tile server, and MAP_MARKER pins your points of interest. It's ideal for GPS trackers, fleet displays, and location dashboards on the P4's large screen.
