This project is a proof-of-concept for a low-power e-paper clock, using the display of a Motorola F3 and the MSP430 Launchpad.

A few notes on the video:
* The timer was actually sped up by the factor of 10 for demonstration purposes, so 1 minute on the clock is actually 6 seconds in the video.

* Completely powering down the display also has its disadvantages. As you can see, the display needs to be initialized every time you power it up again (thus the flickering), which isn't needed when just disabling the 32KHz clock.

* The second row (showing 000000) is just a counter, counting the total hours the microcontroller ran, intended for a runtime test with a goldcap or CR2032 battery.
