Raspberry Pi 7 Segment Display Library

This is a simple library to use M 7 segment displays connected to N *595 Shift registers. All pin numbers are based on the GPIO.BCM numbering scheme. You will need the RPi.GPIO module available.

This module also requires my PiShiftPy library.

Basic Usage

###Defaults
595 Data: 18
595 Clock: 23
595 Latch: 24
No of 595's: 1
No of Displays on each 595: 1
Displays are Common Cathode: False

###Code

import Pi7SegPy as Pi7Seg

Pi7Seg.init()
while True:
    Pi7Seg.show([1]) # Display 1 on a single 7 segment display connected to 1 Shift register

Advanced Usage

import Pi7SegPy as Pi7Seg

Pi7Seg.init(17,27,22,2,4) # Initialize with Data:GPIO17, Clock:GPIO27, Latch:GPIO22, with 2 shift registers and 4 7 segment displays on each register

while True:
    Pi7Seg.show([1,2,3,4,5,6,7,8], [1,2,5]) # Display 12345678 on 8 displays connected to 2 registers with dots enabled on the 1st, 2nd and 5th Digit
