Nobody has written firmware for this board. This is fluidbox'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. fluidbox on LILYGO T-Display-S3 (silhouette): refuse. Refused because sensors: this app needs a vector sensor (gravity direction, read every step, so tilting the device pours the liquid) and the device declares none at all. It runs at 42 particles against the reference 130 (how many particles the fluid is made of), bound by panel area (170x320 at one per 1268 px). 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.
