找了很久,詳細的看了一些資料,才找到問題....
 原來是ADPCFG 沒設定為DIGITAL-MODE. 不過說也奇怪ICD2-DEBUG模式可以RUN, PROGRAM後RUN卻不行.  我覺得dsPIC30F2010的DATASHEET寫的很亂, 不像以前PIC16和PIC18的DATASHEET寫的有條理明確. Microchip應該要改善一下.不過很高興能找到問題.

QEI功能在icd2-debug模式RUN ,poscnt都可正常讀取值,但是在燒入後run,poscnt的值一直都是0,無變化.請問設定上是否有哪些錯誤或有需注意的地方...
void Initial_QEI(void) //ENCODER輸入設定*4倍 { ConfigIntQEI(QEI_INT_DISABLE); OpenQEI(QEI_INT_CLK & QEI_INDEX_RESET_DISABLE & QEI_CLK_PRESCALE_256 & QEI_GATED_ACC_DISABLE & QEI_INPUTS_SWAP & QEI_MODE_x4_PULSE & QEI_DIR_SEL_QEB & QEI_IDLE_STOP , QEI_QE_OUT_ENABLE ); }
