Re: Detection of Tiny Blobs from QQVGA

Hi,

However, blobs of 1pixel wide X 1 pixel Height (single pixel Blobs) are not getting detected when I set: pixels_threshold= 1, area_threshold=1
Tried with setting "pixels_threshold= 0, area_threshold" too.
Any suggestion would be of great help, please.

Thanks,
Regards.

Detection of Tiny Blobs from QQVGA

Hi, I run the following code on my QQVGA Grayscale image: img.mean(1, threshold=True, offset=5, invert=False) blobs = img.find_blobs([(0,64)], pixels_threshold= 1) Unfortunately, only the blobs marked with " Red-Arrows " are detected. There are at least 35 tiny-blobs left undetected, in each image. ...

How to set "Reference Voltage" to raise an Interrupt from External Sensor

Hi, I want to connect an FSR sensor (Force Sensitive Resistor) to H7. Generally, FSR connects 3.3V, GND (through as Resistor) and any Input PIN (which receives changing voltages from FSR based on the pressure put on the FSR surface). Pins already in use on my H7: Pins P4 & P5: Already in use for UAR...

Re: OSError: failed to init WINC1500 module

Working !!
Again, my fault.
Soldering was not good on some PINs, perhaps.
After re-soldering all PINs, it's working.

I am extremely sorry for the inconvenience caused.
Thanks for the patience and immediate responses.

Re: OSError: failed to init WINC1500 module

All the three scripts have the following 2 lines:

wlan = network.WINC()
wlan.connect(SSID, key=KEY, security=wlan.WPA_PSK)

When run, the above lines executes fine.
And that's it. Print statements that are there in the remaining portion of the code don't show up in the Termina of IDE

Yes. It is connecting to my Router. Please see enclosed image. No problem there. Then, tried the following: "connect_1.py", "tcp_client_1.py" and "dns_1.py" But, the output of print(wlan.ifconfig()) is not showing up in the Serial terminal. It just displays the following and stays there: >>> Trying ...

Re: OSError: failed to init WINC1500 module

Now... there is a new problem.
The Serial Terminal output remains at:
>>> Trying to connect... (may take a while)...
Running in Station mode...

Tried with:
"connect_1.py", "tcp_client_1.py" and "dns_1.py"

What can be the reason?

Re: OSError: failed to init WINC1500 module

Solved !!! You are right. Thank you. In the absence of soldering, the pins don't ensure proper/slug contact. After soldering, now, at least one set is working (M7 + WiFi Sheild). Hopefully, the other WiFi Shield should also work and with H7 also. Now... there is a new problem. The Serial Terminal ou...
