accVector (Function)

This function will retrieve the current acceleration vector measured by the accelerometer.

Returned values are in mg.

Input:

None

Output:

x : DINT

The acceleration force measured on the X-axis (in mg).

y : DINT

The acceleration force measured on the Y-axis (in mg).

z : DINT

The acceleration force measured on the Z-axis (in mg).

Returns: INT

Declaration:

FUNCTION accVector : INT;
VAR_INPUT
  X : ACCESS DINT;
  Y : ACCESS DINT;
  Z : ACCESS DINT;
END_VAR;

Example:

INCLUDE rtcu.inc
 
PROGRAM example;
VAR
  x,y,z : DINT;
END_VAR;
  accOpen();
BEGIN
  accVector(x := x, y := y, z := z);
  ...
END;
END_PROGRAM;
