Thanks Eric for your answer. In fact, in the telosb motive data sheet, http://moss.csc.ncsu.edu/~mueller/rt/rt11/readings/projects/g4/datasheet.pdf It is written on page 24 that *"If expansion pin 10 (ADC3) is used for digital I/O instead of analog inputs, R14 must be populated with a 0 ohm resistor to enable the pin for digital I/O (GIO0) on the microcontroller. R16 must be populated with a 0 ohm resistor to enable GIO1. R14 and R16 are located on the top side of Telos between the USB controller and the radio."*
So, what i want to do is that i want to use the expansion pin 10 (ADC3) and control the I/O signals through tinyos. More precisely, i want to attach an electronic switch, which enables or disable an external device (antenna) with the signal i provide it to this expansion pin 10 (ADC3). Do you have any idea how to achieve this?
