N6 Ribbon Cable?

OpenMV Boards

Hello,

On earlier threads it’s been mentioned that a new ribbon cable design compatible with the PAG7936 camera is in the works. Is there any timeline for when we could expect this to be available?

Thanks.

I just got samples this week from SingTown. I need to check them and approve production.

This code is confirmed to fix the PAG7936 with the 80mm cable:

import csi
import time

csi0 = csi.CSI()
csi0.sleep(True)
time.sleep(0.01)
csi0.reset()  # Reset and initialize the sensor.
csi0.pixformat(csi.RGB565)  # Set pixel format to RGB565 (or GRAYSCALE)
csi0.framesize(csi.HD)  # Set frame size to QVGA (320x240)

#csi0.snapshot(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 = csi0.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.

The issue is that the noise from the MIPI transceivers corrupts long streams of i2c writes over long cables unless it’s silenced before initing the sensor.
