[Tinyos-help] MSP430 ADC first reading

Hello all,

I've encountered a weird issue when using the msp430's adc on tmote invent.
The first reading I perform after bootup always gets a smaller value then I
should get. For example, I have a voltage which should return around 0x0916
adc counts, but instead I get around 0x00AE . This happens for the first
reading after boot on each channel, so I suspect the cause is software.

Has anyone else noticed this too?
