基于TL16C550C实现TMS320C6711的异步串行通信

Realization of TMS320C6711's UART communication based on TL16C550C

为解决TMS320C6711在通信接口控制能力方面存在的缺陷,提出了一种基于TL16C550C实现TMS320C6711的异步串行通信的新方案。该方案采用一片可编程的自动流量控制专用车行异步接口芯片(TL16C550C)来扩展TMS320C6711的串行异步接口,结合简单的寄存器配置程序来实现TMS320C6711的高速异步串行通信。同时,给出应用电路实例及进一步改进的方法。

This paper introduces a new resolving plan of the realization of TMS320C6711's UART communication based on TL16C550C. The plan adopts a special chip of asynchronous communications element with auto flow control to expand the interface and simple program of configuration registers to realize high -speed TMS320C6711's UART communication. The hardware circuit is relatively complicated, but the interface is simple. The data are transmitted far away. A better effect is shown in the communication.
