Hi folks!
Was just wondering if I could ask for some guidance. I'm completely new to this Raspberry Pi and programming stuff so bear with me if some of the things I ask come across a bit naive.
I've got as far as getting my DAC+ hat working and the samples being read from an SD card nicely. Haven't got as far as adding buttons yet, but the real question I have for you is in the display.
Rather than the typical 7-segment display, I want to use a 14-segment as I intend to display text corresponding to the name of the current sample folder.
I have the Adafruit HT16K33 backpack with 2 x 0.54" 14-seg displays. I've followed the Adafruit instructions regarding hooking the display up via the GPIO pins and downloading and installing the Blinka and HT16K33 libraries.
I'm assuming I can at least get the thing displaying some text, for example 'ABCD' by creating a file called "14seg.py" at /home/samplerbox containing the following code:
import board
from adafruit_ht16k33.segments import Seg14x4
i2c = board.I2C() display = Seg14x4(i2c)
display.print("ABCD")
Then, by using SSH, use the commend Python3 "14seg.py"
However, I get no life from the display, but instead the following errors:
pi@samplerbox(rw):/home/samplerbox$ python3 14seg.py
Traceback (most recent call last):

Any pointers on what to investigate on this would be hugely appreciated.
All the best.
