This repository contains a simple Python module, which can control a seven segment display attached to a Raspberry Pi.

I used the following 7 segment display (datasheet here), and wired it up in the following way:

Raspberry Pi Pin	7 segment display pins
1	3,5,11,16, via a resistor (3.3V)
11 (GPIO 0)	1 (segment a)
12	14 (b)
13	12 (c)
15	10 (d)
16	4 (e)
18	2 (f)
22	13 (g)

Example usage:

% sudo python # so that you can access the GPIO pins
>>> from sevensegment import *
>>> import time
>>> s=sevensegment.SevenSegmentDisplay()
>>> s.set(1)
>>> for i in range(0, 10):
...     print("Displaying %d" % i)
...     s.set(i)
...     time.sleep(1)
... 
Displaying 0
Displaying 1
Displaying 2
Displaying 3
Displaying 4
Displaying 5
Displaying 6
Displaying 7
Displaying 8
Displaying 9
>>> s.off()
