摘要
介绍了AD公司的串行模数转换芯片AD974及TI公司的TMS320C6711芯片多通道缓冲串口(McBSP)的工作原理。采用McBSP的SPI(SeriesProtocolInterface)工作模式,可将McBSP与AD974直接相连,从而无须任何转换而实现高速串行数据传输,并给出了AD974芯片与McBSP的接口电路及软件设计。
The principle of serial analog-to-digital converter chip AD974 and the structure of TMS320C6711 muhichannel buffered serial port (McBSP) is introduced. Based on SPI (Series Protocol Interface) mode, A/D chip is connected to McBSP. In this mode, the data can be transfered directly without any convertion. The interface circuit and software design are shown finally
