| 摘 要： | TMS320DM642(DM642)作为一款高性能的多媒体DSP有着广泛的应用前景,作为C6000系列,它不具备通用异步串行收发接口(UART)。基于TDS642EVM介绍了通过板载TL16C752B实现UART数据通信的方法,论述了UART相关寄存器的初始化设置及串行通信函数在图像显示主程序中的调用等,实现了DSP与PC104机间的异步串行通信,完成了图像叠加显示功能。

| Abstract: | As a kind of high performance digital signal processor(DSP),TMS320DM642(DM642)was widely used in digital multimedia communication.As C6000 series,it was not provided with universal asynchronous receiver and transmitter(UART).Based on TDS642EVM,the serial communication equipped with TL16C752B was introduced,and initializing configuration of some relevant registers of TL16C752B and the function transfers of serial communication in main program were discussed in brief.The serial communication between DSP and P... |
