\brief ADC12 Driver for the GoodWatch.
|
|
|
|
Mostly this uses the internal voltage reference in the ADC to
|
|
measure the battery voltage. For now, we aren't very interested in
|
|
the temperature or other analog inputs.
|
|

/* This part is a bit weird. Basically, we are importing the ADC10
|
|
module that exists in the CC430F6147 but not the CC430F6137. The
|
|
adc.c library will automatically route calls to either the ADC10 or
|
|
ADC12 unit as appropriate, even though our GCC flags say that we
|
|
are only building for the CC430F6137.
|
|
|
|
This way, we can generate one single firmware image that works on
|
|
either chip.
