struct | RI_CGPSLog |
Data structure for the Request "GPSLog". More... | |
Functions | |
LRESULT | RI_GPSLog_WriteData (LPARAM, RI_CGPSLog &) |
Write data to shared memory for "GPS Log". | |
Variables | |
const UINT | RI_MESSAGE_GPSLOG = RegisterWindowMessage(TEXT("RI_MESSAGE_GPSLOG")) |
const UINT RI_MESSAGE_GPSLOG = RegisterWindowMessage(TEXT("RI_MESSAGE_GPSLOG")) |
Message ID for the Request "transfer NMEA Data over RI":
RI_MESSAGE_GPSLOG
RI_GPSLog_WriteData(LPARAM id, RI_CGPSLog data );
RI_NOERROR = NMEA transfer succeeded
RI_NOTADDED = Data not added, because simulation is active
RI_NOTRUN = GPS transfer is stopped
Sends NMEA-Data over RI to the navigation software.
The data sentences "$GPGGA", "$GPRMC" and "$GPVTG" are mandatory.
Be sure that the date in the sentences is correct, because it's needed by some modules. The setences has to be complete, substrings are not supported. Also the NMEA strings must have a correct checksum, overwise they will be discarded.
Don't use this method together with a GPS-Device, the signals would be mixed!
