Other Parts Discussed in Thread: TMS320F28335,
您好，我所使用的硬體是 TMDSHVMTRPFCKIT 和 TMS320F28335 來控制馬達。在執行 "C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.1\HVPM_Sensored\~Docs\Sensored FOC of PMSM" 文件中的 Level2，代碼如下:

rg1.Freq = rc1.SetpointValue;
RG_MACRO(rg1)
// ------------------------------------------------------------------------------
// Measure phase currents, subtract the offset and normalize from (-0.5,+0.5) to (-1,+1).
// Connect inputs of the CLARKE module and call the clarke transformation macro
// ------------------------------------------------------------------------------
#ifdef DSP2833x_DEVICE_H
clarke1.As=((AdcMirror.ADCRESULT1)*0.00024414-offsetA)*2*0.909; // Phase A curr.
clarke1.Bs=((AdcMirror.ADCRESULT2)*0.00024414-offsetB)*2*0.909; // Phase B curr.

PWMDAC_MACRO(6,pwmdac1) // PWMDAC 6A, 6B

DlogCh2 = (int16)_IQtoIQ15(rg1.Out);
DlogCh3 = (int16)_IQtoIQ15(clarke1.As);
DlogCh4 = (int16)_IQtoIQ15(clarke1.Bs);
#endif // (BUILDLEVEL==LEVEL2)
在進行電流採樣的 clarke1.As、clarke1.Bs 數值都維持在初始值，並沒有改變，想請問:
1. 是中斷點設定的問題嗎? (所設定的觀察點如下圖) 還是有其他原因導致未接收到電流值?
2. 其中 AdcMirror.ADCRESULT1 的數值是如何得到的呢?
