Project description
An MLX90640 is a 32×24 far-infrared array. It does not hand you temperatures — it hands you raw ADC readings plus a calibration EEPROM, and something has to run the conversion. This project makes a deliberate split: the RP2350 only reads the sensor and puts bytes on the wire, and the host PC does the floating-point conversion in numpy. The reason is stated plainly in the README. The MLX90640 temperature formula involves heavy floating-point work, and doing it on the MCU eats enough time to disturb the rhythm of reading the sensor. Keeping the device dumb also means the host retains the full…
