Problems with ADC to perform two consecutive readings on IRIS Mote

Hi everyone,
I have an application that performs several readings consecuitves with different ports of the ADC. Specifically, first read the internal voltage of the microcontroller IRIS, and then performed a reading of a temperature sensor that I have connected. To make both readings the results are erroneous and meaningless. But however, if instead of making two readings modify the application and made only one of two different readings, the value is correct. I think the problem is on the internal components of TinyOS-2.1.1 Adc. Has anyone had the same problem?

If anyone wants I can send you the source code of components that perform the reading of the ADC, which I relied on to implement Tep.

Regards, Antonio Rosa.

If you could post this to tinyos-help, that would be great. Many possible things could be wrong here and that forum is the place to figure it out.
