Definition:

#include <aGPM.tea>




int aGPM_GetMagHeadingFrac(

char addr);

Parameters:

addr

-

IIC address of the specified GPM.

Return Value:

An int with the fractional part of the magnetic heading value from the specified GPM.

Description:

This routine reads the fractional part of the magnetic heading value from a GPM.  A GPS provides a magnetic heading value based on current velocity and direction.  See the documentation for the GPS Module for more details regarding GPM registers and functions.

Example:

#include <aGPM.tea>

x=aGPM_GetMagHeadingFrac((unsigned char)0xD0);


This would set variable x to the fractional part of the magnetic heading value of the GPM.
