本文介绍了TMS320VC5402 DSP的多通道缓冲串行口McBSP的特点,针对用户经常面临的DSP系统与PC机实时交换数据时通信接口标准不兼容的问题,提出了一种新的串行通信设计方案,实现了DSP同步串口McBSP与PC机异步串口RS-232的全双工通信。
This paper introduces the characteristics of multichannel buffered serial port McBSP of TMS320VC5402 DSP. In view of the problem that users often face the incompatibility of communication interface standard when DSP system and PC exchange data in real time, a new design scheme of serial communication is proposed. Realizes the full-duplex communication between DSP synchronous serial port McBSP and PC asynchronous serial port RS-232.
