摘要
为了解决TMS320C6713与GPRS模块间的接口问题,提出了一种基于多通道缓冲串口(McBSP)与专用异步收发器(MAX3111)的扩展方式。简要介绍了TMS320C6713的MCBSP接口和MAX3111芯片,并结合McBSP和MAX3111各自的特点,提供一种基于SPI通信方式的异步串行通信方案。该方案软、硬件设计简单,易于实现。
In order to solve the capacity for interface between the TMS320C6713 and GPRS module, a new scheme is presented for expanding the UART interface by using multi channel buffered serial ports and dedicated chips of the asynchronous communications transceiver （ MAX3111 ）. McBSP and MAX3111 are introduced briefly. According to the characteristics of the McBSP and MAX3111, a scheme based on the communication of SPI of the UART communication is presented. The scheme is simple and easy to realize.
