AIUI your script relies on the "raw" thermal data from radiometric jpegs saved with the flir app, is that correct?
That raw data is already preprocessed in some way that does alter the geometry of the image, as far as i can tell; which is likely the reason for the 320x240 resolution.

yes, its a workflow for the Flir radiometric jpgs

The true sensor raw is useless signal for you.

The microbolometer generates some noise and drifts, which are filtered with the flat-field correction (FFC):
Pixel Noise
Row Noise
Column Noise
Uniformity

The next step is the bad pixel mapping.

After then the Flir firmware converts (in radiometry mode) this post processed signal to a value which is linear to radiance [W / m^2 (per nm)].
This computational result is the so-called 14 Bit Raw signal (like ThermalLinearFlux14BitImage)

GitHub repository:

Flir One Drivers: https://github.com/da-nie/FlirOneDrivers
Flir One Control: https://github.com/da-nie/FlirOneControl
Flir One Raw Analizer: https://github.com/da-nie/FlirOneRAWAnalizer

This looks rather interesting as there are Windows 7 drivers. Maybe they will work with Windows 10? How are they installed?

No! Windows 7 Drivers can not be installed! These drivers are compiled for Windows 7, but they can not be installed. Only XP...

Flir One Gen 2 and STM32F4Discovery. :)

https://github.com/da-nie/nightvision

Display 320x240 with HX8347D controller.
Connect:
D0-D7 - PE4-PE11
CS - PE12
RD - PE13
RW - PE14
RS - PE15
RST - PE2

Project from Keil 5 with Cube MX. If 3 second not image then microcontroller is restart.

STM32F4 and Flir One Gen 2

Please i need desperately your expert help.
As i didn't manage to work my F1G2 android device, i decided to teardown and check some things.
When i connect the device with micro usb-to usb and then to old WIN XP PC, founds a new hardware.
I tried to install the xp drivers made by Da-Nie but it doesn't work. The device remains with yellow exclamation mark.
Then i supposed that the medium black chip might need re flowing. I did that but no luck again.
I 'm ready to re-flow the big Atmel chip also. But before doing this, i ask you help and advice from experts.
The device power on and after some orange red light, the green light flashes but my samsung A5 android cannot recognize it.
The shutter on off and on again.
Any help will be appreciated.
TIA

Dear Da-Nie

thank you for reply.
Please let me explain with photo's:
The chip i did reflow is the big square one

Win XP founds only ONE UKNOWN device.
This is the Atmel chip side.

This is the Lepton module from device.

I don't know what chip envolves with the Lepton module though.
TIA

Yes, this is lepton camera module. I was wondering how this module involves with the other chips like the Atmel. In the worst case, i will take this module and try to do another interface with it.
Or i can buy a lepton breakout board and use it. My question is how to test if this module is ok or not? Is it a good idea try to reflow the Atmel chip or it has no interference with the camera module?
TIA

I have yet to see a LEPTON failure through natural means rather than abuse.

Take care if considering a reflow on the micro. It is supported with epoxy and this prevents the IC free floating on the liquid solder balls. Cracked solder balls could actually separate leaving a gap between the IC and PCB pads. You really should remove the securing epoxy and the IC, before re-balling and re-fitting. You could try a simpler approach though.

Yes i noticed that. I put hot air at 180 degrees and melt carefully the epoxy. My question though is:
If i manage to reflow the Atmel with no harm, will it be the cause of the fault? What does it doing?

Today i just finished the reballing of the chip and tomorrow i will try to put it in his place.
I also did write down the test points connections with the chip and i will post them for reference here.

Hi, I haven't tried this on earlier versions of Raspbian based on debian jessie, but the latest version based on debian stretch is really simple to install working v4l2loopback:

sudo apt install raspberrypi-kernel-headers libusb-1.0-0-dev dkms v4l2loopback-utils v4l2loopback-dkms
sudo modprobe v4l2loopback video_nr=0,1,2,3

If it's OK, as per previous replies a way back, I'll create a git repo with the contents of flir8p1-gpl.tar (unless someone has already done it that I missed?)

Hey. Did you manage to solder the chip? I have Flir One with the same problem. To begin with, I warmed up the atmel a little. The thermal imager worked a week. And again it does not work.

Is there any way of keeping the flir one awake, or waking it up through usb?  It has a very short timeout where it goes to sleep and then you have to physically press the button.  This is no good if it's mounted somewhere (outside of a house, drone, etc)

Question about the color palettes (*.raw files): How do you create a specific color palette? Is rainbow.raw a standardized file format? Where can I download more color palettes or how can I create more? Is a source code available?

Unfortunately the device is still in coma!
I 'll wait for new equipment and i will try one last time to "revive" it and the i 'll post the results here.
C ya!

I had the same trouble. Atmel chip reballing does not solve the problem.
In my case, the nand flash chip reballing helped. After this device works good.
