MarshallSoft GPS Component for C/C++

The MarshallSoft GPS Component for C/C++ (MGC4C) allows any C/C++ program to receive and decode standard NMEA 183 sentences from a GPS receiver connected to the RS232 serial port. Requires a 32-bit or 64-bit Windows C/C++ compiler.

MGC4C includes the following:

• Uses the Windows Win32 API (Win64 API for 64-bit apps) for serial port input.
• Works with both real and virtual serial ports.
• Runs as a background thread unattended.
• The most current GPS data is always available on demand.
• Most commonly used NMEA sentence types automatically decoded.
• Does not depend on support DLLs.
• Several latitude/longitude calculation functions included.

Several example programs are provided, including examples for Microsoft Visual C/C++ (MSVC), Microsoft Foundation Class (MFC), Borland C/C++, Borland C++ Builder (BCB), Watcom C/C++, LCC-WIN32, and MinGW.

MGC4C can be used in the development of Win32 and Win64 applications running under Windows through Windows 10. The evaluation version of MGC4C is fully functional. Registration is $115 for email delivery and includes one year free updates.

MGC4C is also available with source code for $195.

Current version is 2.2 (June 8, 2011).
