This is an updated guide to get both visible and thermal camera image overlay working on a Raspberry Pi running the new Raspbian Jessie with Pixel OS using our custom pylepton library for the FLIR Lepton. Pixel greatly simplifies setup time over previous methods.
- 1x Raspberry Pi 3 (it will also work on the Pi 2)
- 1x MicroSD Card 8GB or larger. This is what we use here: SanDisk Ultra 32GB microSDHC Card
- 1x FLIR Lepton Thermal Imager
- 1x FLIR Lepton Breakout Board
- 8x Female to Female jumper wires
- 1x Keyboard and Mouse
- 1x Micro USB cable and wall adaptor
- 1x Monitor with HDMI port or HDMI to DVI converter
- 1x HDMI cable
- 1x Ethernet cable
- 1x Raspberry PI 5MP Camera Board Module v2
P1 —Download Required Software
1 — Follow this link and download "RASPBIAN JESSIE WITH PIXEL"
2 —Once downloaded insert your micro SD card into your computer, then follow one of the guides on this page to write the Raspbian Image to your micro SD card.
3 — When the image file has been written to the micro SD card, insert the card into your Raspberry Pi
P2 — Connect the Pure Breakout board to the Raspberry Pi
1 — Match your female to female jumpers wires to the images below (note: your jumper wires may differ in color). You can also use the list below.
- CS -> Pin 24, CE0
- MOSI -> Pin 19, MOSI
- MISO -> Pin 21, MISO
- CLK -> Pin 23, CLK
- GND -> Pin 6, GND
- VIN -> Pin 1, 3V3
- SDA -> Pin 3, SDA
- SCL -> Pin 5, SCL
2 — Once you have attached the breakout board, connect your monitor, keyboard, mouse, ethernet cable, and finally the micro USB cable to power the board.
P3 — Software Installation
Secret discount, use the code iReadPiKitBlog2016 (case doesn't matter) for 10% off the Raspberry Pi 3 FLIR Lepton Dev Kit
1 —Once you get to the Pixel desktop, open terminal
2 — Next install python-open cv: sudo apt-get install python-opencv
3 — Next download pylepton from github: git clone https://github.com/kekiefer/pylepton.git
4 — Then cd to the newly downloaded pylepton folder: cd pylepton
5 — Now install pylepton software: sudo python setup.py install
6 — Next it is time to change some of the raspberry pi settings, type the following to get to this menu: sudo raspi-config
7 — First enable the camera.
8 — Now go to Advanced Options.
9 — Then enable SPI.
10 — Return to the Advanced Options menu.
11 — Now enable i2c.
12 — Now we need to exit raspi-config and reboot.
13 — Once the raspberry pi has rebooted and returned to the desktop, open terminal again. Then type the following to test out the pylepton_overlay software: pylepton_overlay -a 155
14 — Congratulations, you should now see a thermal overlay image on the screen. To close this window press ctrl+c . Now it's up to you to use pyLepton to create your own interesting Lepton applications on Raspberry Pi. Definitely let us know what you make!
