pip3 install adafruit-circuitpython-mlx90640

Usage Example

import time
import board
import busio
import adafruit_mlx90640

i2c = busio.I2C(board.SCL, board.SDA, frequency=800000)

mlx = adafruit_mlx90640.MLX90640(i2c)
print("MLX addr detected on I2C", [hex(i) for i in mlx.serial_number])

mlx.refresh_rate = adafruit_mlx90640.RefreshRate.REFRESH_2_HZ

frame = [0] * 768
while True:
    try:
        mlx.getFrame(frame)
    except ValueError:
