[Tinyos-help] ADC characteristics in MICA2 board

[Rafael Aguilar Velez]

Thank you for answering Michael. Having control in the digitalization band tends to increase the resolution of the readings of the accelerometer. If I reduce the range of the band of digitalization I can have more "points" and so I can get more resolution.  
For example if I read from +-2g I will have less resolution than reading between +-0.1g.
 
Do you know how can I do this?
 
Regards,
 
Rafael

The ATMEGA128 has 10 bit ADCs, see the controller manual for
all the detail you could ever hope for.

I don't know what you mean by "digitalization band"...
