import time
# Import all board pins.

# Import the HT16K33 LED segment module.
from adafruit_ht16k33 import segments # Create the I2C interface.
i2c = busio.I2C(board.SCL, board.SDA)
# Create the LED segment class.
# This creates a 7 segment 4 character display:
#display = segments.Seg7x4(i2c)
# Or this creates a 14 segment alphanumeric 4 character display:
display = segments.Seg14x4(i2c)
# Or this creates a big 7 segment 4 character display
# display = segments.BigSeg7x4(i2c)
# Finally you can optionally specify a custom I2C address of the HT16k33 like: # display = segments.Seg7x4(i2c, address=0x70)
# Clear the display.
display.fill(0)
# Can just print a number
display.print(42)
time.sleep(2)
# Or, can print a hexadecimal value
display.print_hex(0xFF23)
time.sleep(2)
# Or, print the time
display.print("12:30")
time.sleep(2)
display.colon = False
# Or, can set indivdual digits / characters 
# Set the first character to '1': 
display[0] = "1"
# Set the second character to '2': 
display[1] = "2"
# Set the third character to 'A':
display[2] = "A"
# Set the forth character to 'B':
display[3] = "B"
