【摘要】 从软件和硬件两个方面设计了一种简单、实用的DSP与串行AD/DA转换器的接口电路。该方法中AD/DA转换器与McBSP串行口直接相连 ,不需要占用并行数据总线 ,避免了总线冲突。此方法已成功应用于各种速率的数据采集与处理系统中更多还原

【Abstract】 This paper designs a simple and practical interface between serial AD/DA converter and DSP. In this design, the AD/DA converter is directly connected to the serial port McBSP, not occupying DSP’s parallel data bus and will avoid from bus interference. The technology derived in this paper has been successfully applied in data acquisition and processing systems with several rates.更多还原
