Thanks. I will go back to the soldering. But before I do that.
Would you mind looking at the following.

Although my code (that I post below) does not crash - I notice that I get some warning by my python builder.
I d like to verify with you if this might show that I am doing stuff wrong in the set up and software installation that I did in the beginning.

Code:

Code: Select all

import time

# Import all board pins.
import board
import busio

# Import the HT16K33 LED segment module.
#from adafruit_ht16k33 import segments
import segments
import ht16k33

# Create the I2C interface.
i2c = busio.I2C(board.SCL, board.SDA)
display = segments.BigSeg7x4(i2c)


# Clear the display.
display.fill(0)
time.sleep(2)
display.fill(1)
time.sleep(2)
# Can just print a number
display.fill(0)
time.sleep(2)

# Or, print the time
display.print(":")
time.sleep(2)

print("ready")

It's most likely hardware related. I tested here using fill(1) and it worked as expected - everything lit up. The argument is indeed a bool, not an int. So the messages and warnings are correct. But very much doubt it's related to what you're seeing. Passing in a 1 ends up behaving like true.

None of the warning look significant. And they're in the libraries, not your code.

Redo the soldering. See https://learn.adafruit.com/adafruit-gui ... -soldering and https://learn.adafruit.com/collins-lab-soldering for advice.

Thank you.

I am going to do the re-soldering this weekend.
I have also ordered a second display - and try if that new will act different.
(I need two in the end.)

Thanks - once again.

hello all,
thanks for you help.

this is how I went:
got new display and had trouble to get it working. (nothing happened at all)
after a few hour I limited the weakest link to the jumper wires. And it appeared that those were bad.
the previous one now also works.

I am not sure if that declares the "only dots" issue.
but at least - I am happy.
