[Tinyos-help] gio0 problem on tmote sky

[André Miguel de Almeida Marrão Rodrigues]

Thanks Michael and Urs

Just a few comments to close the issue:

T2 has HPL, HAL and HIL interfaces. The selecIOFunc() was not in
GeneralIO (which I think is a HIL interface, and the one application 
developers should use) but in HplMsp430GeneralIO it exists.
So, to be on the safe side I use it...

After reading the specs again I recognize the "(and only then)", that 3 
words were
very helpfull. So, for sure there is no need , in my case, to use the gio0 
and add a resistor in R14, ADC3 (Port63) is just fine.

Thanks,

André Rodrigues
