In a lot of articles I read about Arduino and now netDuino, I see the use of an external reference voltage. In particular instance, the use of the external 3.3v reference voltage made some analog readings more accurate and stable. I’m experiencing a similar inconsistancy in reading resistance values from a simple resistive divider and was wondering if an external reference was supported on a FEZ Panda or if it’s even needed. I’ve search for AREF on this forum, but it yielded no results.
Anyone even know what I’m talking about or am I just that confused? ;D
