This programme hangs after an hour or so (time to be determined).
It stops responding to button presses requiring removal of power to restore it.
Previously it ran all day until I added the pushbuttons.

This is an example for our Monochrome OLEDs based on SSD1306 drivers
Pick one up today in the adafruit shop!
------> http://www.adafruit.com/category/63_98
This example is for a 128x64 pixel display using I2C to communicate
3 pins are required to interface (two I2C and one reset).
