pip3 install adafruit-circuitpython-mlx90640Usage 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:
# these happen, no biggie - retry
continue
