A Solution Of Storage-Card Control Based On μC/OS_II

Opposed of current embed-system`s limitted savage, this paper gives a solution. The solution mainly base on arm micro-controller, it uses a real-time operating systerm to manage SD storage-card, and uses usb device interface to transfer data, finally develops the SD storage-card to be a Mass-storage device. In hareware parts, the micro-controller uses S3C2410A, which is produced by Samsung company; SD card uses an 256MB storage-card, which is produced by SanDisk company, it communicates with S3C2410A by SD insert port. USB device uses PDIUSBD12 USB interface chip, which is produced by Philips company. Software parts include the haredware`s initial, the driver of SD card and USB device; and an simple FAT16 pattern`s file systerm,which is used for manage the data in SD card; finally, useμC/OS-II real-time operation systerm to schedule and manage the whole system. In the end of this paper, it gives the application of this solution,analylizes the solution`s, and the debug tools, which is used during the whole designing process.
