The dot is almost a Mica2. Not 100%-it's more like a mini Mica2. Most Mica2 code will work on a dot. > Nadeem Jamal wrote: >> >> I am using the MICA2Dot nodes and the Crossbow mote works development >> platform. >> >> As I have understood rssi reading can be acquired using ADC0 on the >> mica2dot.

My understanding is the dot is something like a Mica2 with some sensors hardwired on and anything not directly needed deleted. Probably accessing the ADC directly for the strength reading is having side effects on other sensors sharing that pin, or confusing the radio. -- The difference between the right word and the almost right word is really a large matter- it's the difference between a lightning bug and the lightning. -Twain _______________________________________________ Tinyos-help mailing list [email protected] https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
