Driver for the MLX90640 thermal camera
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
Installing from PyPI¶
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-mlx90640
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-mlx90640
To install in a virtual environment in your current project:
mkdir project-name && cd project-name python3 -m venv .venv source .venv/bin/activate pip3 install adafruit-circuitpython-mlx90640
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]) # if using higher refresh rates yields a 'too many retries' exception, # try decreasing this value to work with certain pi/camera combinations mlx.refresh_rate = adafruit_mlx90640.RefreshRate.REFRESH_2_HZ frame =  * 768 while True: try: mlx.getFrame(frame) except ValueError: # these happen, no biggie - retry continue for h in range(24): for w in range(32): t = frame[h*32 + w] print("%0.1f, " % t, end="") print() print()
