There's code in tinyos-2.x-contrib/ecosensory/apps/ReadMoistureSensors/
that uses the MSP430 adc's in multichannel mode, where you get data from several
channels as fast as possible. I have not done a tutorial write up of it, but plan to.
It depends on a sensorboard that is a mux to get more effective channels, but you can
still use it as a guide for ADC0, ADC1, ADC2, ADC3 reading. It's a mostly compete app
that sends readings in a struct as messages over the radio every second. In the near future,
I will add low power mode of operating to it, and some received message controls for
asking for a single reading of all now, changing the reading time and period, etc.
