Erratic tick mechanism for hacked clock.
Original project by Bart Basile http://e2e.ti.com/group/microcontrollerprojects/m/msp430microcontrollerprojects/664670.aspx
Adapted by Tom Price February 2014:
- Target microcontroller MSP430G2231 (smaller and cheaper than MSP430G2553)
- Tick sequence length adjustable using single define
- Bit array used to store sequence to save memory
- Layout of H bridge adapted slightly
- Energise time adjusted for the particular clock that I happened to have
