摘要
针对目前大多数数字信号处理器(DSP)只有同步串口情况,给出了一种利用DSP的多通道缓冲串行口(McBSP)实现与PC机进行异步串行通信的简单硬件接口电路,并以TMS320C5402为例,编写了实现两端口通信的软件程序。
At present,most of the DSPs only have synchronous serial ports.Therefore,the article provides the simple interface circuit to realize the serial communication with PC by using DSP's McBSP,and taking TMS320C5402 as an example,gives the software program for their communication.
