基于ti公司54x系列DSP的串口通讯程序，本程序可以实现dsp与PC的实时通讯，本人已经验证过，不过你的板子上要使用16C550串口通信模块，它占用DSP的一个端口，用来实现与PC的通信，程序的开始是对它的内部寄存器进行定义。-Series DSP chip serial communication procedures, The dsp procedures can be achieved with the PC real-time communication, I have tested, But the blame on you to use 16 C550 serial communication module, which occupied a DSP ports, used to achieve and PC communication, the start of the process and it is the internal registers to be defined.
