Lepton sensor diagnostic failed

[helmarw]

Do you know if the sensor is working at all? Did you test it e.g. on a raspberry first with standard code from flir?
just asking because my first Lepton i got from digikey was broken from the start. after some discussion with flir customer support and digikey i got a refund (not really a 5cent device, so it makes sense to give it some effort :) ).
second one i bought from mouser and everything work fine from the start ...
I dont think you can do much wrong with this DIY Thermocam, i built it myself and using it ever since ...

I tried to build the code for the raspberrypi_video (see here : LeptonModule/software/raspberrypi_video ) without success.

I am using a raspbian dist, and not able to install qt4-dev-tools (needed for qmake).

Anyway, I have ordered a new sensor to see if it can works just by switching them.

I have actually managed to get it compiled with qt5 and run the software.

It seems to works even if it's very slow and the refresh is not fast at all.

I have plugged all back to the DIY-Thermocam PCB, and still get the same issue during the boot

EDIT:

I tried to installed a previous firmware version. The V3.0 gives more info on the possible Lepton failure. It seems that the issue comes from the I2C as shown in #40. Using a multimeter I have checked all the connection from the lepton module to the teensy, all seems okay.

I bought a new sensor, solved the issue.

BTW, I have also designed an updated version of the 3D printed enclosure (thinner and more smooth). I will try to make another iteration to fix some issues and upload both STEP and STL if someone wants it.

IIC OK , SPI OK, but touch continue lcd show "lepton error , try to reset.." I don't know where is wrong , how to deal with it
