Openmv 2.0.0 Firmware 3.0.0 no framebuffer display

[MLCMichaelLamber]

hello,
I have made today an update to openmv 2.0.0 and firmware 3.0.0 (cam m7).
It is not possible to see the frame buffer in the display.
On all other IDE I get the frame buffer.

Thanks

Michael

Hi, is the frame buffer disabled?

[MLCMichaelLamber]

Do you mean in the IDE?
In the IDE tehe frame buffer is enabled.
Is there an other way to enable the frame buffer?

Thanks

Michael

Okay, can you give some more information for me to reproduce?

We haven't seen this error before. As far as I know the current IDE works fine.

Screen shots?

Hello,

how can I attached the screenshot?
When I will add files (pdf, jpg, bmp). I get the info "invalid file extension"
Info:
OpenMV IDE 2.0.0 (german)
Firmware 3.0.0 cam m7
OS Windows 10 Professional 64 bit

When I connect the cam serial monitor works.
In the framebuffer I see the message "kein Bild" (no picture)
All text is in german.
I change the language from german to english.
The framebuffer did not function.

Thanks

Michael

Program:

Code: Select all

# Hello World Example
#
# Welcome to the OpenMV IDE! Click on the green run arrow button below to run the script!

import sensor, image, time

sensor.reset()                      # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA)   # Set frame size to QVGA (320x240)
sensor.skip_frames(time = 2000)     # Wait for settings take effect.
clock = time.clock()                # Create a clock object to track the FPS.

while(True):
    clock.tick()                    # Update the FPS clock.
    img = sensor.snapshot()         # Take a picture and return the image.
    print(clock.fps())              # Note: OpenMV Cam runs about half as fast when connected
                                    # to the IDE. The FPS should increase once disconnected.

Question, do you get text output on the serial terminal when you run the program and does the Green arrow switch to a red stop button?

[MLCMichaelLamber]

Yes I get data in Serial output Windows.
Frame Buffer is enabled.
THANKS
MICHAEL

[MLCMichaelLamber]

Yes The Greenpeace Button Switched To Red one

Mmm, I don't know what the problem is. Um... Is there any physical damage to the camera lens system? Can you check that the lens cap is not on, the lens is mounted well, there's no tape on the camera see sensor, etc? The IDE will generate errors if it's unable to pull images from the camera... So, the input image data has to be broken.

Using color bars mode should help narrow down the issue:

Code: Select all

sensor.set_colorbar(True)
