Inappropriate ioctl for device about pylepton HOT 7 CLOSED

pylepton is just for the breakout board. You should look at https://github.com/groupgets/purethermal1-uvc-capture

from pylepton.

Try something like this:

def capture(device="/dev/spidev0.1"):
    with Lepton(device) as l:
        return (data, _ = l.capture())

from pylepton.

What was the problem here? Can we close this issue?

Hi, I'm getting a similar error and can't resolve by substituting the device to device="/dev/spidev0.1. was this ever resolved? I don't really understand what my error means as well...

I ran the example usage code (saved the file on my machine as "test_pylepton.py") and tried to run it using python3 and got this error:

Traceback (most recent call last):
File "test_pylepton.py", line 5, in
with Lepton() as l:
File "/Users/.../GetThermal/pylepton/pylepton/Lepton.py", line 82, in enter
self.__handle = open(self.__spi_dev, "wb+", buffering=0)
PermissionError: [Errno 1] Operation not permitted: '/dev/spidev0.0'

Could you please advise what I'm doing wrong here?
My camera and setup work fine with GetThermal or other apps.

Any help would be very much appreciated
Thanks!

GetThermal? Do you have a breakout board or a PureThermal board?

Thanks for your reply @kekiefer. I have a PureThermal Mini connected to my mac over USB.

I meant that I was able to follow the installation of the GetThermal app:
https://github.com/groupgets/GetThermal

And it works well with my camera, as well as just using it as a "normal" webcam with OBS. I'm interested in using the PureThremal mini with OpenCV+python to do some analysis and get temperature readings for each pixel. I was hoping to use pylepton to do so.
Thank you for your help!

Check your cable setup. An incorrect setup will throw this error when using pylepton 3.0.

This guide from FLIR shows the correct GPIO setup: https://lepton.flir.com/forums/topic/pylepton-overlay-guide-2-0-for-raspbian-pixel/
