7-bit, 0x08 to 0x77. Detect passes the address it found; the last one used here is
remembered. Applies on the next connect.
Measurement
Applied in the browser, so changes take effect on the next frame. Leave Reflected at
roughly Ta − 8 °C unless a specific background temperature is known.

Every frame carries all 192 pixels — the two subpages differ in which offset set applies, not in which pixels are present — so no accumulation is needed. The EEPROM is Hamming-encoded and is decoded before use; skipping that step yields calibration that looks plausible and is wrong. Maths ported from the Melexis MLX90641 driver library (Apache-2.0).
