Abstract:

This paper proposes a GMS90C32 singlechip GPS display system design method. These two aspects of the system design is presented based on GPS timing GMS90C32 MCU display from hardware and software, in the part of the hardware design of the system, firstly, every function module and related technical parameters, then for each function module is introduced in detail and the circuit connected to realize the function of the system; in the part of software design first, given the system software design of main program, and then analyzed the GPS module information and serial procedures, 12864 LCD driver. Finally, the system test shows that, this system can not only display the GPS module timing information, and can be sent to the outside timing information. The use of wireless module and the corresponding communication protocols, so that other devices can receive access to the system in the GPS timing information through the wireless module. So without integrated GPS module size in the equipment, so as to reduce the equipment volume and production cost.
