Eric, I'm not positive it isn't the hardware, but I am POSITIVE I have the voltage that should return around 0x0916 adc counts. I also have run this on two different motes (both invent) and noticed the same thing on adaptations that Urs Hunkeler did of the original tmote invent drivers.
It can be some hardware feature (capacitor transients, etc) but if it was, the ADC drivers should start it on the boot sequence, so the first readings would not be erroneous. I can solve this on my own, with a dummy reading just to clear that, but it wouldn't be a very elegant solution and this can be a problem to more people on the future. I did read some of the msp430 datasheet, but there is too much detail and complicated state machines, and the code of the msp adc modules are very complicated too. I can inspect more, but I think that maybe it should be clearer for people who had more hands-on contact with the adc. ~Dimas~ On Wed, Jun 18, 2008 at 1:55 PM, Eric Keller <[EMAIL PROTECTED]> wrote: > Are you positive it isn't hardware?
