I've searched through tinyos-2.x with find and have not found any comparator 
code.
I'm thinking of using the MSP430F1611 comparator instead of its DAC
since comparators are often on a processor chip.  Also, I need more drive than 
the 0.5 mA
the DAC can provide, also using the DAC stops using ADC6 ADC7 on the 
MSP430F1611.

Timer code in tinyos seems not to use the hardware timer inputs so far -- they 
are physically shared with
the voltage comparator on the MSP430F1611.

So, I wonder if anyone is planning such timer trigger inputs soon and how to 
deal with hardware conflicts
where using one port feature stops using another...

I'm doing the voltage comparators groundwork for calibrated soil moisture 
sensors that draw 10 mA each for
10ms before taking a reading, and require a solid 2.50 V for excitation to give 
accurate data.
