编码器无法获取电机转子角度数据

Other Parts Discussed in Thread: BOOSTXL-POSMGR, C2000WARE

TI工程师,你好!我用TI编码器读取函数配合IDDK部分程序,位置在:\ti\c2000\C2000Ware_MotorControl_SDK_3_01_00_00\libraries\position_sensing\tformat\source。按理来说,我转动电机轴,应该能在仿真界面expression列表中看到转子位置变化才对,但是我发现这个数据始终为0。  另外:我用的实验器材有:电机(安装有多摩川t-format编码器).F280049C launch pad的板子。还有TI的BOOSTXL-POSMGR(这个是编码器接口板)
