| 摘 要： | TMS320F28335 是TI 公司的一款数字信号处理芯片，具备丰富的外设接口，器件可靠性强，在机载
机电、接口、控制领域得到应用。面对嵌入式控制器多机通讯的需求，使用TMS320F28335 的McBSP 接口和
DMA 功能设计一种时分复用的多机多通道通讯方法，硬件接口直连，软件通过DMA 自动完成帧数据收发，
避免通讯对DSP 内核的占用，实现一种经济、可靠的多机通讯方案。

| Abstract: | TMS320F28335 is a digital signal processing chip from TI company, which has rich external interfaces with
high reliability.TMS320F28335 is applied widely in the field of airbone electrical, interface and control. A method with
McBSP interface and DMA function is designed for the demand of the multi-machine communication by embedded
controllers based on TMS320F28335.The hardware interfaces of multi-controllers are directly connected, and the software
automatically completes the data transfer through the DMA by this design, avoiding the occupation of the DSP
kernel by the communication. This design realizes an economical and reliable multi-machine communication solution. |
