摘要
本文介绍了一种采用TMS320VC5509A自带的USB模块来实现USB数据传输的方案,对该DSP内部的USB模块的构造及其传输原理做了分析,详细的介绍了如何利用CCS内部集成的片级支持库(CSL)来实现USB设备固件程序的设计,并给出了相关的部分代码。该方案大大降低了系统硬件设计的复杂度和调试的难度,提高了系统的集成度和稳定性,适用于便携式设备中。
This article introduced a method to realize USB data transmission using the TMS320VC5509A＇s own USB module , analyzed the DSP＇s interior USB module＇s structure and its transmission principle, how to realize the USB firmware procedure design using chip support library which is integrated in CCS has been introduced in detail, and the related partial codes has been given. This method greatly reduced the complexity of the system＇s hardware design and the debugging difficulty, it enhanced the system integration rate and the stability, using in the portable equipment is suitable.
