[Tinyos-help] Battery ground on the Telos Connector

[Shahin Farshchi]

Hi Joe,

 

I hope you had a great weekend.  I'm building a neural interface board for
the Telos.  In my first revision, I ties the circuit ground with analog
ground (pin 9 on the header).  Upon realizing that the mote was acquiring
garbage, I tied pin 9 to the battery ground (messy), which resulted in
everything working perfectly.  I now understand that analog ground is not
battery ground, which is what my circuit needs.  Is there a way to tie
analog ground to battery ground in software?  Even when attaching a signal
generator to the Telos, I've needed to tie the (-) terminal from the
generator to battery ground to get the mote to acquire the signal properly.

 

Many thanks!

Shahin
