Pylepton Overlay Guide 2.0 for Raspbian Pixel

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.

Required Parts

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

Raspberry Pi Micro SD Card

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.

1 —Once you get to the Pixel desktop, open terminal

Terminal Icon

Terminal Window


2 — Next install python-open cv: sudo apt-get install python-opencv

OpenCV

Yes to OpenCV


3 — Next download pylepton from github: git clone https://github.com/kekiefer/pylepton.git

Pylepton Git


4 — Then cd to the newly downloaded pylepton folder: cd pylepton

cd pylepton


5 — Now install pylepton software: sudo python setup.py install

pylepton 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

raspi-config


7 — First enable the camera.

Camera

Camera Yes


8 — Now go to Advanced Options.

Advanced


9 — Then enable SPI.

SPI

SPI Enable


10 — Return to the Advanced Options menu.

Advanced


11 — Now enable i2c.

i2C

i2C Enable


12 — Now we need to exit raspi-config and reboot.

Finish

Reboot Yes


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

pylepton_overlay


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!
