gpsPowerLP (Function)

Similar to the gpsPower() function this function controls the power to the GPS receiver.

This function operates the GPS module at a lower communication speed than gpsPower(). When using gpsPowerLP the satellites in view will not be retrieved and gpsUpdateFreq() is only supported with 1 position per. second.

Input:

power : BOOL

Returns: INT

Declaration:

FUNCTION gpsPowerLP : INT;
VAR_INPUT
  power : BOOL;
END_VAR;

Example:

INCLUDE rtcu.inc
 
PROGRAM test;
 
// Turn on power to the GPS module
gpsPowerLP(power := TRUE);
 
BEGIN
  ...
END;
 
END_PROGRAM;
