| 摘 要： | 为了实现DSP芯片与串行A／D芯片的多信号通信，设计了TMS320F28335的多通道缓冲串口（McBSP）与串行A／D转换器ADS7863的硬件与软件接口。该设计中A／D转换器与McBSP串口直接相连，不需要占用并行数据总线，避免了总线冲突。通过在CCS环境下编程、调试，得到了满意的实验结果，验证了该接口设计的正确性。

| Abstract: | The hardware and software interface between TMS320F28335 McBSP and ADS7863 was designed for the realization of multi-signal communication between DSP and serial A/D converter. In this design, the A/D converter is directly connected to the serial port McBSP without occupying DSP＇s parallel data bus. The solution avoids the bus impact. By programruing and debugging under CCS environment, the satisfied experimental result is achieved, and the correctness of the interface design is verified. |
