Problems with ADC to perform two consecutive readings on IRIS Mote #40

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
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.
