Lepton 3.1R - functional but no image on GetThermal

[mhparant]

Hello

I just received my Lepton 3.1R and I am unable to view the live image on GetThermal for Mac (screenshot attached).
I am able to see the streaming image on Zoom and MaxMSP.

I reinstalled GetThermal for Mac but it's the same sad result.

Someone can help me with this?

[mhparant]

Anybody here reading our questions? Seems like this app needs update for the new Lepton 3.1R.

At some point Apple changed the way permissions to get access to USB devices worked. It could be that you will have better luck running the program from the command line, with sudo. Also, this way there will be some logging output, in case there is something special that needs to happen to run the 3.1R.

Hello Kurt
Is "sudo GetThermal" the proper command line?
My terminal doesn't find that command
sudo: GetThermal: command not found

[metanav]

How did you install it?

[mhparant]

You mean the software?
I downloaded GetThermal-v0.1.3-MacOS.dmg and GetThermal-v0.1.4-MacOS.dmg
I tried both versions. Same result blank screen on GetThermal 1.3 and 1.4 for the Lepton 3.1R
But with Lepton 3.5, I can see the live image.

[griffin175]

You need to tell the command line to run the program. Refer to the mac OS terminal user guide

Try this: sudo open -a GetThermal.pro
Strike that, the .pro is part of the source code, not the executable. Find where you installed the program and run with sudo open -a from there.

You mean the software? I downloaded GetThermal-v0.1.3-MacOS.dmg and GetThermal-v0.1.4-MacOS.dmg I tried both versions. Same result blank screen on GetThermal 1.3 and 1.4 for the Lepton 3.1R But with Lepton 3.5, I can see the live image.

The binaries should be inside the /Applications/GetThermal.app/Contents/MacOS directory.

After sudo running the GetThermal appimage on Ubuntu 23.10 with a Lepton 3.1R I see the failure:
UVC_GetAttribute failed: -9.

The error happens in this function call in 'leptonvariation.cpp':

LEP_RESULT LeptonVariation::UVC_GetAttribute(LEP_COMMAND_ID commandID,
                            LEP_ATTRIBUTE_T_PTR attributePtr,
                            LEP_UINT16 attributeWordLength)
{
    int unit_id;
    int control_id;
    int result;

    unit_id = leptonCommandIdToUnitId(commandID);
    if (unit_id < 0)
        return (LEP_RESULT)unit_id;

    control_id = ((commandID & 0x00ff) >> 2) + 1;

    // Size in 16-bit words needs to be in bytes
    attributeWordLength *= 2;

    QMutexLocker lock(&m_mutex);
    result = uvc_get_ctrl(devh, unit_id, control_id, attributePtr, attributeWordLength, UVC_GET_CUR);
    if (result != attributeWordLength)
    {
        printf("UVC_GetAttribute failed: %d", result);
        return LEP_COMM_ERROR_READING_COMM;
    }

    return LEP_OK;
}

The 3.1R CCI Command ID is new 05-070850-. I think that's the main issue here. If FLIR has an update for the Lepton SDK, that should include support for the 3.1R.

Also, line 136 of leptonvariation.cpp needs || getOemFlirPartNumber().contains("500-0758-01") added to bool LeptonVariation::getSupportsRadiometry()

So here's a screenshot of what I tried today with your suggestion

Unfortunately It is still a blank screen for the Lepton 3.1R
I had previously plugged the camera before opening the app.

Note - If I change the parameters in GetThermal, even if I dont see the live image, and "PERFORM FFC", these settings are saved and visible in the live image in another software (like MaxMSP or Zoom). AGC is also available. It is really just the update of the live image that is missing it seems.

[mhparant]

I just tried with Lepton 3.5 and the same procedure shows the live image.

But the AGC is all grayed out and it can not be modified.

.

[mhparant]

At some point Apple changed the way permissions to get access to USB devices worked. It could be that you will have better luck running the program from the command line, with sudo. Also, this way there will be some logging output, in case there is something special that needs to happen to run the 3.1R.

For me the USB seems to work since I can read the live image of Lepton 3.5 but not the 3.1R.
The USB cable is connected to a powered USB HUB as well.

[griffin175]

Also, line 136 of leptonvariation.cpp needs || getOemFlirPartNumber().contains("500-0758-01") added to bool LeptonVariation::getSupportsRadiometry()

Turns out that addition was all that was needed. Just submitted a pull request, but you can try building my branch now: https://github.com/griffin175/GetThermal/tree/Lepton3.1R-support

Hello griffin175,
Not sure how to install the addition for GetThermal?!

[badgerhoneymoon]

Lepton 3.1R - trying to run on RPi OS - no cam feed. Adding "500-0758-03" doesn't help. Running via VLC on Mac - it works.
