Flir released a SDK for the board more information is posted up on this. No clue- Sounds like you just changing values without understanding what they supposed to be doing. Some great news for those interested in the demo camera. This software you talk about and the arbitrary values. (They recommend 25Mhz) Did you provide that? How about a partnership between Insta360 and FLIR to produce a thermal camera module The future is promising Andy Zahn / Digital Trends Its truly exciting. I suspect they did not include a crystal in the LEPTON to keep the size down and embedded devices usually have access to some kind of constant clock any way.

Now we know Raspbian is not very great at generating consistent clock rates consistently so you may be experiencing problems with this - The same way may other FLIR'ers are experiencing.

Select Camera and press Enter to enable the camera. Go to Interfacing Options and press Enter.

I assume you got it hooked up to SPI correctly but one of the problems seems to be the Input Clock rate. Open a fresh terminal window, and type the following command: sudo raspi-config. So looking around really I noticed the protocol used on the Lepton is VoSPI (Video over SPI) Frankly never heard of that before but its plausible because the frame size is 80 x 60, which is not a crazy amount of data with some kind of AGC applied format which is selectable (Did you select the correct one?)
