Can't get sample script to run? HT16K33 import?

No where in your example do you illustrate imports? A git clone of the project how do you leverage your solution?

#!/bin/env python

Create letters "a", "b", "c", & "d" across all for digits displays

?????

Enable device

digit = FourDigit().setUp()

Create characters

a = digit.TOP_BAR | digit.MIDDLE_BAR |
digit.BOTTOM_BAR | digit.RIGHT_TOP_BAR |
digit.RIGHT_BOTTOM_BAR | digit.LEFT_BOTTOM_BAR
b = digit.MIDDLE_BAR | digit.BOTTOM_BAR |
digit.LEFT_TOP_BAR | digit.LEFT_BOTTOM_BAR |
digit.RIGHT_BOTTOM_BAR
c = digit.MIDDLE_BAR | digit.BOTTOM_BAR | digit.LEFT_BOTTOM_BAR
d = digit.MIDDLE_BAR | digit.BOTTOM_BAR |
digit.RIGHT_TOP_BAR | digit.RIGHT_BOTTOM_BAR |
digit.LEFT_BOTTOM_BAR

Assign custom built characters to device

digit.setDigit(0,a)
digit.setDigit(1,b)
digit.setDigit(2,c)
digit.setDigit(3,d)
