| Abstract: | this thesis introduces the principle of serial analog-to - digital converter chip MAX186 and the structure ofTMS320C6711 multichannel buffered serial port (McBSP). Basedon SPI (Series Protocol Interface) mode, MAX186 ADC is con-nected to McBSP. In this mode, the achieving data can betransmissed into DSP directly without any convertion. The inter-face circuit and the code are shown. The circuit of interface andthe source code are give finally. |
