| Abstract: | With the fast, efficient, plug-and-play and multi-device class characteristics, Universal Serial Bus （USB） has become the most widely used computer peripheral bus. USB firmware development is the focus of the USB system design. It will directly affect the data transmission speed of the USB system. Take voice acquisition system based on TMS320C6747 for example, the target of firmware development and the hardware resources of the USB module in TMS320C6747 are introduced and the USB firmware programming process and related code in detail are described to realize the high speed data communication system between the voice acquisition system and PC. |
