Hi all,
I am working towards a patch that will detect a fall. At the moment i hav a patch that gives a warning if the x value from the Shimmer goes below a certain value i.e. the subject is at a certain angle. code to create this block is:
double d = _pInInPin1->GetValue();
CSTR str = "WARNING THE USER HAS FALLEN";

if(d < 1800)
_pOutOutPin1->SetValue(str);
_pOutOutPin1->SetCreationTime(_clockPtr->GetTime());

I want to have a block that will constantly read in the value and maybe store it in an array or list of some kind and compare it to see when there was a sudden change.
The input seems to only be read once if i use double for input pin and i can work on that value but i want values to be constantly input in the block. i was trying using a MatrixDouble as the type for input pin but i am having trouble getting the values to the output pin.


Can anyone help with this?
i would be very grateful, Thanks, Aidan.

You can use DoubleMatrix or a TimeSeries as input (e.g., sampleddata).
Otherwise, you can store the data inside your block and generate the output only when the event your are detecting occurs.
