TMS320C6000系列DSP的McBSP功能扩展

The Function Extension for the McBSP of TMS320C6000 Series DSP

McBSP(多通道缓冲串口)是TMS320C6000系列DSP(数字信号处理器)的标准配置,是一种增强的串行接口。McBSP具有良好的扩展特性,可实现多种功能的接口扩展。分析了McBSP的基本工作原理,给出了将McBSP扩展用做GPIO(通用输入输出)接口、UART(通用异步收发器)和SPI(串行外围接口)的配置方法、工作模式和设计例程,具体应用表明这些扩展功能均能正常稳定工作。

McBSP（Multi-channel Buffered Serial Port） is a standard component of TMS320C6000 DSP, and is a kind of enhanced serial interface. McBSP has a good expansibility characters, and can be extend to various type of interface port, This paper analyzes the principle of McBSP, and presents the configuration method, operation mode and program routines for configuring the McBSP as the GPIO, UART and SPI. Every function of the McBSP is working well in the practical computer system.
