Based On ARM Platform Portable Integrated Navigation Display Control Design And Implementation

With the rapid development of industrial control electronics, wireless terminals, the demand for embedded systems gradually increased, requiring higher and higher.In this thesis Devkit8500D hardware platform to support Linux2.6.32 system kernel with integrated 1GHz ARM Cortex-A8 core, integrated navigation system software based on embedded Linux system design and application problems. On the basis of the consolidated derivative display and control station needs analysis is proposed based on the Cortex-A8 Portable Comprehensive guide display and control console design.This paper analyzes the hardware platform to study the embedded ARM hardware initialization,boot the kernel and extract the memory, to establish the root file system,and operating system on ARM boot process. Secondly, this interface development tool Qt carried out a detailed study,which involves the study of human-computer interface design,serial communications, network communications, and small embedded database.Then, the system development environment to build in=depth study,based on the PC virtual machine and install the Linux operating system and installs the cross-compiler environment,Qt development environment, etc., and then transplant the corresponding Qt libraries, the development board of the target environment set the variable, the relationship between the signal and the groove,the event handling mechanism were analyzed. Finally, the application of the detailed design of the system is studied based on the Ethernet interface communication technology integrated navigation Cortex-A8-wire devices,serial communication technology,embedded database technology and complete the corresponding software design.In accordance with the general process of software design school, through the Comprehensive guide display system software from the analysis, design, implementation,complete exposition. Finally, most of the functions designed Cortex-A8-based integrated navigation display and control system is basically achieve integrated navigation system display and control system software users,including the serial interface module interfaces,networking interfaces, backstage SQLite database, people achieve machine interactive interface. Interactive interface which includes the main interface, operating mode, parameter binding, device management, navigation schemes. Capable of stable operation on the development board.
