@ Raymond : Congratulations! Nice work. I find Thermal Imaging very interesting.
Could you save the raw data to SD Card at full rate on one Cog and automatically play it back from the SD card as NTSC on another COG at the same time by adding delays. (or is that what you were going to try? )
I would like to save to SD at full rate (actually can be full rate divided by 3, since every new frame repeats twice so that actual frame rate is 9 Hz instead of 27) and preview at the same time.
For preview, might to USB to PC, NTSC or display on a local LCD, not sure yet.
@ Rayman: I think I misspoke earlier when I said we want to use this to get temperature...
We already have thermocouple probes for that...
Why not use this? :
With the FLIR ONE SDKs, developers have access to absolute temperature data for all pixels and control the Lepton camera’s shutter mode, in both manual and automatic settings.
That might be interesting.
But, the problem with optical temperature measurement is that you have to know the emissivity of the target and that can vary a lot...
Needed 30' of cable between camera and Propeller, so I had to change a few things.
I added 10k resistors to ground on all the signal wires.
Also, I added some "NOP" delays into the driver to lower the data rate.
This version only captures 9 frames per second instead of 27. But, I think that's OK since the actual new frame update rate is 9 frames per second anyway.
Also, here's the lame windows app I'm using to preview the images.
Next, I need to add in saving 9fps video to uSD card and I'm done. Well, I may add in preview on LCD screen too...

I can see where my kids have been from the footprints and handprints they leave
Only issue there is that serial is to slow to show full 9 frames per second. Only getting ~1 frame per second.
Could use Prop to transmit NTSC and that would be full 9 frames per second. But, I really want to save the raw data....
So, I think I'll add a button to save to SD card and then retrieve from SD card later.

Saving to SD at 9 fps and streaming to NTCS would be a perfect combination for a drone....

Focus is fixed but there are two different version with different field of view options
