"Perform FFC" button in raspberrypi_video No longer works

[ghost]

The previous iteration of the repo on my Pi worked fine, so I know I have the correct settings to communicate with my lepton via I2C.

However FFC doesn't work now ever since the github went from github.com/PureEngineering/LeptonModule to github.com/groupgets/LeptonModule.

Also, I did run the executable with sudo.

It probably wasn't the move but rather subsequent changes made around then (e.g. pull request #14 or #16). Can you verify if this is the case? Maybe try running the code at version a9905796

I'm not aware of any changes I made in #14 or #16 that would have caused FFC not to work (I've been using it without any new issues (the fact that manually triggering FFC sometimes locks up the camera is nothing new)). Which subprogram are you using (e.g., raspberrypi_qt, raspberrypi_video, raspberrypi_capture)?

[MartyMacGyver]

Narrowing down, you must be using raspberrypi_video. I just re-downloaded the repo and rebuilt raspberrypi_video (qmake && make) and ran it - commanded FFC (by clicking "Perform FFC") works - I can hear and see the shutter closing and opening.

Did you download the current release to a clean area and rebuild it? Did you make any customizations previously (different I2C port, etc.)? Are you seeing video?

[PureEngineering]

did you enable the i2c module in the config.

Yes, I am using raspberrypi_video.

Yes, I do have the I2C module enabled.

No, I didn't make any customizations.

I'll try the build at a990579 to comfirm.

Thank you all for the tips.

[MartyMacGyver]

Let us know what exactly isn't working currently - just the FFC button? Something else as well (e.g., no video)?

Turns out I was using such an old Lepton that the FFC function wasn't featured yet. Sorry for the confusion guys. haha

No problem - thanks for the update!
