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.
