Definition:

#include <aGPM.tea>




int aGPM_GetHDOP(

char addr);

Parameters:

addr

-

IIC address of the specified GPM.

Return Value:

An int with the units of HDOP (times 100) from the specified GPM.

Description:

This routine reads the units of HDOP (times 100) from a GPM.  HDOP is a "horizontal dilution of precision" value.  A discussion of this value is beyond the scope of this document.  See a GPS reference for more details.  See the documentation for the GPS Module for more details regarding GPM registers and functions.

Example:

#include <aGPM.tea>

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


This would set variable x to units of HDOP of the GPM.
