Nobody has written firmware for this board. This is tinydraw's own C, compiled against that board's own device.json through packs/web and run at its panel size with its buttons, and it proves exactly that much: no driver, no timing, no memory pressure, no silicon. tinydraw on Waveshare ESP32-S3-Touch-LCD-2.8 (silhouette): go. Every dimension the app states is met by what the device declares. This target is unverified against silicon, so every number above came from a datasheet, not from a board. A verdict is a comparison of two documents, never a prediction that the port runs.
