基于VK3366的DSP异步串行通信的设计

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 multiport 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.
