Seven Segment access

[rabagliati]

I have written some python code, which writes to the 7 segment displays.

I adapted the code from the Happy Birthday example.

It works - but only after I have run the demo - otherwise the LEDs remain off.

To repeat, if I run my code right after boot, the LEDs are blank.

If I run the Happy Birthday demo, the next time I run my code the LEDs display my numbers.

Here is my code - simplified

#! /usr/bin/python2

import datetime
from Adafruit_LED_Backpack import SevenSegment

segment = SevenSegment.SevenSegment(address=0x70)

now = datetime.datetime.now()
hour = now.hour
minute = now.minute
second = now.second

segment.clear()
segment.set_digit(0, int(hour / 10))    
segment.set_digit(1, hour % 10)         
segment.set_digit(2, int(minute / 10))  
segment.set_digit(3, minute % 10)        
segment.set_colon(2)
segment.write_display()

I needed this :-

segment.begin()

Closing.
