Hi Francesco, As far as I know the 51-pin connector is hardwired and cannot be disabled. I had a look at the drivers for the mts300 board, and it seems that most sensors on the module are activated or deactivated with dedicated pins on the connector. From my quick glance I get the impression that the sensors are only deactivated when explicitly done so, which only happens if the sensors are actually used (and even then I am not sure it would happen for all the sensors). For some reason, the pins of the microcontroller are by default set to logical one (I think the microcontroller uses less power that way), which in turn has as an effect that the sensors would be activated (and thus draw power). Now I really only had a very quick look and so don't know whether all sensor would be activated, or only some of them.
To turn the sensors off, you could wire to the MicaBusC component and explicitly turn off the corresponding pins. MicaBusC provides access to some of the microcontroller's pins through the GeneralIO interface. The pins I found are: - Photo (light): Int1 - Temperature: Int2 - Sounder: PW2 - Microphone: PW3 - Accelerometer: PW4 - Magnetometer: PW5 If you wire, e.g., the microphone power pin to MicPower, you can disable the microphone in the Boot.booted event with "MicPower.clr(); MicPower.makeInput();". Let us know whether this helps. Cheers, Urs On 10/25/2010 03:28 PM, Francesco Ficarola wrote: > Hi everybody. > > How can I disable the 51-Pin Connector?
