From the schematic it looks like PW5 controls the power to the Mag section of the micasb/MTS310. This pin seems to be toggled by the start() and stop() functions in sensorboards/micasb/MagM.nc. But I don't see those functions being called in the test app code... which was too convoluted for me to follow.
I would first check PW5, aka, PortC Pin5: pin 40 on the Atmega or pin 34 on the expansion connector, to see what it's doing. Then probably just junk the whole test program and write a simpler one using MagM directly, maybe based on apps/Sense. MS bahare nadery wrote: > Hi, > > I have a problem using MTS310 sensor boards.
