Example code not helpful - draws black on black

[herrmanthegerman]

I assume that the example code given on README.rst should be considered a "smoke test" or "hello world" program to enable the user to check that his/her display can be addressed and is basically working.

That said, with executing display.fill(0) it draws a black background on my black display. I didn't see any change at all.

I suggest to change this to display.fill(1) so it draws some other "color" than black on the display. At least this works for my SSD1306 OLED display.

Does that make sense?

sure, please submit a PR to revise it!

This should be fixed now, by mirroring the code in examples/ssd1306_simpletest.py.
