請問33FJ256MC710的QEI功能
如何正確設定? 我參考技術資料以及曾老師的書 卻無法正成使用QEI 以下為我的QEI code -------------------------- AD1PCFGL |=0x0030; // Disable the A/D pins 4 and 5 AD2PCFGL |=0x0030; // Disable the A/D pins 4 and 5 TRISBbits.TRISB4 = 1; //set RB4&RB5 as input TRISBbits.TRISB5 = 1; ConfigIntQEI(QEI_INT_DISABLE&QEI_INT_PRI_0) ; OpenQEI( QEI_MODE_x4_MATCH & QEI_IDLE_CON &QEI_INPUTS_NOSWAP & QEI_NORMAL_IO & QEI_INDEX_RESET_DISABLE &QEI_DIR_SEL_CNTRL , QEI_QE_CLK_DIVIDE_1_4&QEI_QE_OUT_DISABLE ) ; // 設定為4倍模式，閒置時繼續操作 // 保持預設腳位，正常輸出入 // 關閉指標重置功能，方向選擇控制設定 QEI_New = ReadQEI( ) ; //read position -------------------------- 是否有腳位設定錯誤?或其他錯誤?  感謝大家幫忙..
