Flir Lepton Thermal Imaging Sensor + Gameduino 2

I recently got my hands on a pair of thermal imaging sensors and have spent the last week bringing them online in my spare time. These are absolutely incredible devices that I believe will pave the way to consumer devices incorporating thermal imaging cameras. The footprint of the camera module (and optical assembly) is about the size of a dime. The resolution is 80x60 at 14bpp which is remarkable despite sounding low.

I have successfully implemented a driver for the Lepton module and displayed frames on an LCD. This is all running on an STM32F4 processor on a . Attached to it is a which incorporates the graphics processor. I have implemented my own colorization and min/max scaling before uploading the frames to the GPU.

Front System Overview
I have used some simple jumper wires to interface with this camera. This setup is running at 21MHz with no issues. I am using a provided by . You can pick up one from if you are interested. The Lepton module can be ripped out the for now.

Rear System Overview and Second Camera (future project ;])
I wrote my own driver for the Lepton core and the FT800 graphics processor. Continue reading for more details!
