摘　　要：重点介绍了利用DSPs的多通道缓冲串口McBSP实现与A/D、D/A串行接口的设计。TI公司TMS320C67x系列DSPs的McBSP有两种配置方式,一种是配置成串口的模式,一种是配置成通用I/O的模式,本文分别用这两种模式进行了A/D和D/A接口的设计,其硬件及软件的实现方法简单、方便,可节省程序代码空间和CPU运行时间。This paper presents the interface design between McBS Pand A/D, D/A. There are two McBS Pconfiguration ：one is configured as serial model ;The other is configured as common I1/O model. In this paper, these two models were used to carry out the A/D and D/A interface design. Its hardware circuit and software programming are simple, so it can economize program code space and CPU running time.
