Hi
I'm coming up against an issue on Shimmer2r when wiring in both the
magnetometer (kinematics board) and pressure sensor (GPS/Press board) into a
'BoilerPlate'-style app (i.e. a general do-it-all app). Upon adding the
pressure sensor hooks, and without calling it's init anywhere, the app will no
longer get to the Magnetometer.readDone event when sampling the magnetometer.
To demonstrate, i have gone and added the pressure sensor hooks (NB no call to
PSInit.init is present) to the BoilerPlate app in contrib. i.e.
adding this to BoilerPlateAppC.nc
components PressureSensorC; BoilerPlateC.PSInit ->
PressureSensorC.Init; BoilerPlateC.PSStdControl ->
PressureSensorC.StdControl; BoilerPlateC.PressureSensor ->
PressureSensorC.PressureSensor;
and this to BoilerPlate.nc
interface Init as PSInit; interface PressureSensor; interface
StdControl as PSStdControl;
event void PressureSensor.tempAvailable(int16_t * data){ }
event void PressureSensor.pressAvailable(int32_t * data){ }
The result is no streamed sample output to the ShimmerConnect host software,
since the app never gets to see the Magnetometer.readDone event (checked by
sticking an led toggle there).
I know i could just add a compile flag and some ifdef statements to get around
it, but then the app loses it's generality. Any ideas on this? Can the wiring
of the two sensors coexist without interfering with the other?
thanks
