基于C8051F020的USB OTG通信系統(tǒng)的設(shè)計與實現(xiàn)
[Abstract]:In order to meet the market demand of portable devices from the point-to-point USB interconnection of PC, it is proposed that -USB OTG technology be born in good time only for USB devices with full speed, high speed and super high speed. The technology has become an indispensable interface and function for mobile devices because of its convenience. Aiming at this development trend, based on the design idea of MCU USB, this paper implements a set of USBOTG communication system with C8051F020 of SiliconLaboratory Company as processor and ISP1362 of Philips Company as USB processing chip, and investigates and analyzes the mainstream demand of the market. Provides the ability to support interoperation of internal file data between OTG devices without PC. The development process of USB OTG interface equipment from hardware design to software implementation is discussed in detail. In the aspect of hardware design, the schematic diagram of control module USB module, system storage module and other auxiliary modules is given. The design and implementation of USB OTG functional equipment system software are analyzed emphatically. According to the idea of modularization and hierarchy, the structure of the system software is given, including the system application module, the main machine function module and the peripheral function module. At the same time, the program design idea of each function module is introduced, the running result of the system is analyzed, some debugging data are given, and the functions of the system are verified by the actual debugging and testing work. Based on the development platform of C8051F020 and ISP1362, this paper studies the USBOTG protocol and FAT32 file system protocol. At the end of this paper, the idea of designing USBOTG general protocol stack is put forward. The protocol stack has good cross-platform porting function and powerful task mount interface, which can easily serve other project requirements.
