The Seeduino comes pre-programmed with the open-source Arduino sketch (download link in the files section) and with the wires connected. Just supply 5v to the Seeduino through a standard micro-USB cable and the display will power up.
Since the source Arduino sketch is included, you can easily understand the initialization code and the routines that are used to update the display.
