Revisions:
Applicable SLCD revision: 3.3
Applicable Commands Reference: 1.0

Functionality:
This release includes all the functionality of the previous release and also includes
a bug fix. Bit #4 in the status message was being set even after the proximity sensor timeout had expired.
A fix was added to prevent interrupt servicing of the proximity sensor following the timeout expiration. Also,
the proximity sensor timeout was erroneously set to 60 seconds. This has now been changed to 30 seconds in 
version 0.6.

Bugs: none known.

RELEASE:
08/16/07: EX 0.7

Revisions:
Applicable SLCD revision: 3.3
Applicable Commands Reference: 1.0

Functionality:
This release includes all the functionality of the previous release and also includes
a workaround. The proximity sensor ISR now adjusts for occasional noise on the interrupt
line that was causing "false" interrupts. A 1.5 V falling edge can be noted on occasion 
when the pin puller is retracted. The ISR now waits at least 200 msec before assuming that
the interrupt is valid. Interrupt servicing prior to firing remains the same. 

Bugs: none known.
