Dear Community, I have the following questions about TLE9879QAX40's sensorless FOC code: In code: /*AdcResult[2] => 1st ADC Meas.** **AdcResult[1] => Second ADC measurement. */ AdcResult0 = Emo_AdcResult[2u] & 0x0FFFu; AdcResult1 = Emo_AdcResult[1u] & 0x0FFFu; Emo_AdcResult[3u] = AdcResult0 + AdcResult1; /*Result 0 minus CSA offset*/ R0mioffs = AdcResult0 - Emo_ Svm.CsaOffsetAdw; /*CSA offset - result 1*/ OffsmiR1 = Emo_Svm.CsaOffsetAdw - AdcResult1; /*Result1 - Result0*/ R1miR0 = AdcResult1 - AdcResult0; /* Calculate the current according to the sector number */ Sector = Emo_Svm.StoredSector1; switch (sector) { { Case 0: { Emo_Svm.PhaseCurr.A = R0mioffs; Emo_Svm.PhaseCurr.B = R1miR0;

1. Is this Emo_Svm.PhaseCurr.A the corresponding three-phase A-phase current?

2. How do I convert the actual collected value to the current?

Follow the formula: (0.4*5+I*R*G)/Vref *1023. The converted current values do not match.

I would be grateful if you could answer my question, thank you, thank you!

Dear Team,

Thank you for your kind support,

is there any way to do wake up MCU after VS is goes down to 3V , without POR (Hardware reset)?

Thank you in advanced!!

Is there a downloadable link for this, please?

请教一下

硬件：TLE9879 evb 

软件：LIN_MASTER_EXAMPLE_TLE987X

1.是否可以通过串口转usb在pc 串口工具上看lin数据

2.有什么电脑端pc 工具做lin主给板子做通信呢
