摘要
介绍了异步串口扩展芯片VK3366的性能特点,设计了基于数字信号处理器件TMS320C6713B并口与VK3366扩展多串口的硬件电路方案,且在CCS 3.0环境下完成了TMS320C6713B初始化VK3366的软件编程。电路设计实现了系统高效多串口通信扩展,增强了系统通信接口控制能力。
The characteristics of VK3366 used for asynchronous serial portable expansion are introduced. A hardware cir- cuit based on TMS320C6713B and VK3366 was designed for muhiport serial expansion. The software programming for the VK3366 initialization was realized in the CCS3.0 environment. The efficient multi serial-port communication expansion was im- plemented and the control capability of the system communication interface was improved by the design of the circuit.
