| Embedded System Design p1ays an important ro1e in modem electric design. Miniaturization and/or intelligentice instrument carried out,and owned independence intelligence property.It takes more and more extensive application in each domain,i.e national defence, space navigation, commuicaion, traffic, industry, energy and also. In this project the writer try to introduce EASYARM2200,that is the hardware platform based on LPC2214,which is micro processor based on ARM,and it's deve1oping support platform ADS1.2. The hardware platform includes principle party of circuit i.e power suply, system reset, clock, externed memory, and communication control,such as UART0/1,system dedug(JTAG),RS232/RS485 protocol and interface.and then,make analysis of system startup, processor running mode, externed BUS interface,memory configuration and management. While the key of embedded system software is embeded Real Time Operation System(RTOS). This thesis will give you the relative information of Embedded System first, emphasized on ARM architecture and the Embedded OS μC/OS-II and the configuration of its parameters.Based on introduction before, the writer pretend to research and analysis how to turn the developping of RTOS on platform used LPC2214 as kernel into realization. Combining with realistic is the specifical characteristic of embeded system. The paper fully discussed how to biult special application of RTOS . At 1ast, this paper tries some practice on embedded system app1ication.build a Monitor system of electric power upon μC/OS-II attached with other function modules(such as ADC. UART). All of them construct a modu1arized, sca1ab1e hardware p1atform. |
