MiSTer marquee on an ESP32 round display or Cheap Yellow Display

MiSTer is an FPGA retro gaming system, and tty2oled is the add-on that shows the logo of the core you're running on a small screen. Erico Mendonca's mister-tty2oled-esp32 re-implements that display side for cheap ESP32 colour screens, and it speaks the same protocol, so the unmodified tty2oled.sh on the MiSTer drives it over USB and the existing grayscale logo library works as is, optionally tinted with a fixed colour, gradient or random colours. It adds full-colour art with wipe, iris and fade transitions, made and previewed in a browser web app. Over WiFi, one MiSTer can drive up to three displays at once through a Go daemon on the MiSTer, and the display can send MQTT notifications. Four boards are supported: an ESP32-C3 Super Mini (with or without its 0.42in status OLED) wired to a separate 1.28in GC9A01 round display; the Sunton ESP32-2424S012C, an ESP32-C3 with the round GC9A01 already on it and nothing to wire; and the 2.8in ESP32-2432S028 Cheap Yellow Display, which shows the same 240×240 art centred on its wider screen and adds touch-to-wake, an automatic brightness option using its light sensor, and an RGB transfer LED. Flash from the browser (Chrome, Edge or Opera on a desktop); your WiFi settings survive updates. On first boot the display opens its own setup network and shows a QR code. A free pack of 77 colour logos from public-domain sources installs through the MiSTer Downloader, and there are 3D-printable cases. You need a MiSTer to drive it. GPL-3.0-or-later; the art packs and some included reference material are under their own terms.
