The Development Of The Real-time Control Platform Based On ARM Embedded System

The embedded system has been widely used for the characteristics of its minute volume, good function, low power and high reliability, which provides new space for the development & improvement of various apparatus and meters. This project constructs the platform composed of the mic-processor AT91M55800A in ARM7 embedded system and the realtime operational system uC/OS-II. And on this basis an applied development is carried out and the design of paperless recorder is realized.The main task of this project is to set up a real-time control platform based on ARM7 chip, and to develop on this platform a meter which is commonly used in the process of industrial control—paperless recorder.(1)A brief introduction is given to the embedded system based on ARM7, and a detailed introduction is given to ARM systematic structure & the embedded operational system.(2)To set up a hardware platform of embedded real-time control based on ARM7 chip: the hardware takes ARM7 mic-processor AT91M55800A of ATMEL corporation as its chief chip; the parallel port bus of the chip is equipped with static memory, procedure FLASH, LCD interface, USB interface, and so forth; the bus of the serial interface is equipped with data flash, EEPROM & ferroelectric chip.(3)The software with the embedded real-time platform has made practical the transplant of the embedded operational system uC/OS-II onto the hardware platform thereby ensuring the real-time state of the platform. This thesis has elaborated the transplanting process of uC/OS-II on the platform, and has given the transplanting code related to the platform hardware.(4)Based on the established embedded platform, this thesis develops a meter which is commonly used in the process of industrial control—...
