Your blog was really helpful. I was doing a similar work on MTS board. and this sampling thing really helped me. Thanks a lot. ok, thanks. Your blog was really helpful.

Instead, I wired the SplitControl interface in each sensor's configuration so that the sensor itself provides SplitControl, allowing your program to turn on and off the sensors as desired.

But I don't see where is this module SplitControlPowerManagerC. How have you changed it? It is not in the provided zip file. Can you please identify the location of this file and the changes that need to be made. You said that you modified the SplitControlPowerManagerC to disable this auto power on and off.

Only turn one sensor on at a time, or the reading at ADC1 will be corrupted and meaningless." This is also reflected in the sensorboard code, so either only light or only temperature can be used at any given time. The currently active light or temperature sensor has to be turned off and the other turned on.

Mon, 20 Jul 2009 00:28:48 +0000 http://www.keally.org/?p=680#comment-255 Have you tried to read light/photo sensor and the temp sensor at one shot? After PhotoC.SplitControl.start() and TempC().SplitControl.start() the signal TempC.Read.ReadDone() never fires. Is it possible to use light/photo sensor and temp sensor at the same time, or have you to stop light sensor before you can read the temp sensor?

To get significant readings from it, I got best results using magnets. I did get the magnetometer to work, but I never bothered to set the gain.
