With　the　development　of　servo　system,　the　data　acquisition　system　demands　higher　sampling　accuracy　and　higher　transmission　speed.　To　used　in　motor　servo　control　application,　a　data　acquisition　system　based　on　AD7367　and　TMS320F2812　is　developed　in　this　paper.　The　hardware　design　develops　the　hardware　platform　of　the　data　acquisition　system,　while　the　software　design　provides　inquiry　mode　and　interrupt　mode　two　methods　to　collect　the　conversion　result.　The　McBSP　of　TMS320F2812　is　compatible　with　SPI　when　configured　in　clock　stop　mode.　The　AD7367　whose　serial　interface　is　compatible　with　SPI　interface　is　fit　to　use　in　data　acquisition　of　motor　control.　The　experiment　results　show　that　the　data　acquisition　system　with　plain　hardware　structure　can　assure　the　sampling　accuracy　and　the　transmission　speed.　©　2010　IEEE.
