【摘要】 TMS32 0 VC5 40 2片上只有两个 Mc BSP口可以用于串行通信 ,而且编程很复杂。为了进一步简化 DSP的串行通信 ,本文首先对利用一片 TL16 C5 5 0来扩展 TMS32 0 V5 40 2的串口 ,以实现串行通信的方法进行了简要介绍 ,然后详细介绍了利用 TL16 C5 5 0实现 TMS32 0 VC5 40 2和 PC机之间的串行通信的具体实现方法。最后还给出了详细的电路图及相关程序。更多还原

【Abstract】 There are only two ports of McBSP on the TM320VC5402 that can be used as serial communication interface, and the programming is very complicated also. In order to simplifty the serial communications of DSP, this paper presents another way to realize the communication with TMS320VC5402 by extending the serial interface with TL16C550. A brief introduction of TL16C550 is given firstly, then the details of the serial communication realization are described. The correlative programs and circuit are also given in the article.更多还原
