Including selection and easy transplantation of open source μC/OS-Ⅱ operating system, completed the transplant in the embedded module, the task to create work; Analyze the system software level and concrete structure from the hardware layer, driver layer, operating system layer and user layer; and analyzes the influence of the actual the power consumption of the system running in different modes and the read-write distance, the influence of moving speed of chip on read and write time.展开更多
文摘This paper mainly completed the design of hardware and software of RFID to read write system. Including selection and easy transplantation of open source μC/OS-Ⅱ operating system, completed the transplant in the embedded module, the task to create work; Analyze the system software level and concrete structure from the hardware layer, driver layer, operating system layer and user layer; and analyzes the influence of the actual the power consumption of the system running in different modes and the read-write distance, the influence of moving speed of chip on read and write time.
