Epaper driver usage for OHSummit badge

README.txt

The above code assumes that you have the driver code for the display and font built-in.

See pull request:
https://github.com/acamilo/micropython/pull/1

It also assumes that you have loaded the happy180.bmp onto the filesystem of the module.

The bitmap was taken from here:
https://github.com/ayoy/micropython-waveshare-epd/blob/master/epd/gfx/happy180.bmp

I loaded the file onto the badge using rshell.
