Nobody has written firmware for this board. This is chrono'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. chrono on LILYGO T-Display-S3 (silhouette): degraded. The cost is stated: panel, 170x320 is under the 200x200 this app asks for, and above the 128x96 it scales to: the layout comes out of the panel, so it fits, smaller. 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.
