I'm really desperate to solve this after weeks of online searches and so would greatly appreciate some help good people! Thanks. Unsupported descriptor subtype VS_COLORFORMAT If you don’t know how to successfully set up a Lepton with Raspberry Pi, I encourage you to look at this tutorial. Step 3: Attach a Lepton to your Raspberry Pi’s breadboard. Running script: "/home/ubuntu/projects/flamesmart/src/uvc-radiometry.py" Make sure your Raspberry Pi is connected to the same router as the WeMo. I suspect it's something to do with the 'enumeration value matching master' but I'm at a total loss as to how to fix this.Ĭode output of running uvc-radiometry.py is as follows. However, even after using the uvc-radiometry.py version from this upstream branch, I still get the -2 error. This change corrects the enumeration value to match master.' This manifested as the "uvc_start_streaming failed: -2" error. 'Commit - added a value to the middle of the types enumeration, which broke our bindings. I've tried many posted solutions, the most relevant being this one įix UVC_FRAME_FORMAT_Y16 due to upstream change Microcontroller Arduino DUE, ESP32, LinkItOne (. However, after fw v-1.0.0, it seems that this Y16 should be on by default. Raspberry Pi, NanoPi, Beaglebone, Thinker Board, Snapdragon Board, Lemon Pi, LattePanda, Banana Pi, Orange Pi. From what I've read online, it seems that I need to update the pure thermal firmware with the right patch to turn Y16 format on and turn AGC off via dfu. When I switch to the UYVY frame format, the video feed displays but the min/max temperatures but they are completely wrong, I assume because it's not outputting raw temperature values. I've spent weeks debugging problems with the uvc-radiometry.py script but I'm still getting a uvc_start_streaming failed: -2 error. I'm trying to use the python uvc-radiometry.py script at to get the raw Y16 data image matrices from the Lepton 3.5 so that I can manipulate them to isolate temperature regions above 200 Deg C. Setup Flir Lepton 3.5 radiometric camera on a Pure Thermal 2 (PT2) board running fw:v1.3.0, connected by usb cable to a raspberry pi 4b running Ubuntu 20.04.5 LTS
