Introduction

Driver for the MLX90640 thermal camera

Dependencies

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

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])

# 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 = [0] * 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()
