Program gets stuck on garbage frame detection. #5

Closed SalahAssana closed 5 years ago

SalahAssana commented 8 years ago

When I tried running the program it gets stuck on line 156 of Lepton.py and I'm not sure why. It was working a minute ago, but now it just keeps detecting all readings as garbage frames.

I have the same issue.

junkert commented 7 years ago

This happens when the SPI device is not responding. Maybe a better error message could be used here.

SalahAssana commented 7 years ago

There is no error message. The only way I even detected this was by putting a bunch of print statement in my code and finding where the code got stuck.

larryfkm commented 7 years ago

Is there any way to reset and recover from this situation instead of getting stuck forever here?

ghost commented 7 years ago

I have this issue also--any fix yet?

kekiefer commented 7 years ago

There was some advice on google groups on how to get LEP_RunOemReboot working through python (due to the lack of a python i2c/cci command processor in this project). https://groups.google.com/forum/#!msg/flir-lepton/aUU_F_iswlE/xSil-2XdBAAJ

It would be great to incorporate something like this into pylepton if it could be built easily.

I am getting this same issue. Has anyone tried putting VIN on a Raspberry Pi 3.3V GPIO and toggled the GPIO to reset the Lepton when this condition occurs?

david-ra commented 6 years ago

The same issue Here. Im using RPI3 with pylepton v3. This is the output of the console:

$ pylepton_capture out.png Garbage frame number resetting... Garbage frame number resetting... Garbage frame number resetting... Garbage frame number resetting... Garbage frame number resetting...

I attach a image of the breackboard scorpio v7 ( without mosi pin, i dont know why ): 20180228_105759

Problem solved. Just a cable problem in the GPIO :P

To wich GPIO pin did you connect CS?

rmnd0 commented 5 years ago

Hardware:

Rpi zero w. FLIR Lepton breakout board. FLIR Radiometric Lepton 3.5.

Software:

Raspbian Stretch.

GPIO pinout: CS -> Pin 24, CE0 MOSI -> Pin 19, MOSI MISO -> Pin 21, MISO CLK -> Pin 23, CLK GND -> Pin 6, GND VIN -> Pin 1, 3V3 SDA -> Pin 3, SDA SCL -> Pin 5, SCL

It doesn't matter if using lepton3 or lepton3-dev, the output of pylepton_capture is always "Garbage frame number resetting...".

I'm running out of ideas before I declare the thermal core broken.

Any thoughts?

Thank you.

rmnd0 commented 5 years ago

I might try that, thanks ;)

Hi,

As i have seen people posting here about black images and garbage frame detection.

When i run pylepton_overlay -a 255 example, I get black images. I am using Lepton 3 and breakout out board v2. I have not found the cause of these black images. Any help would be highly appreciated if anyone has fixed the issue so far.

Thanks, Akshay

Hi all, Any solutions for "Program gets stuck on garbage frame detection" and/or the camera just not sending frames after a certain amount of time?

Thanks
