Initialization is to set a variable as ＂default value＂, including system initialization, software initialization and hardware initialization. However, these three types of initialization are classified in accordance with different layers. This is studied in this paper.展开更多

On the basis of transplant μ C/OS operating system, the system software architecture, application-layer multi- task and the priority has been designed, focuses on the use GPRS tasks, preparation methods GPS tasks. After experimental tests, the system is stable and reliable, the realization of real-time vehicle monitoring. System design methodology for embedded system application development has a certain rcfcrence value.展开更多
