LLC resonant converter - C2000 piccolo - TMDSHVRESLLCKIT

Hello,

I am looking at the code for the TMDSHVRESLLCKIT.  There are four ADC signals that are sampled:

   ADC-A2 => I-SR1/V-SR1/COMP1

   ADC-A4 => I-SR2/V-SR2/COMP2

   ADC-A7 => Vo-fb

   ADC-B1 => Ipri-cs

These channels get set up in the following array:

   // ADC Channel Selection

   ChSel[0] = 9; // Dummy read for first sample bug
   ChSel[1] = 9; // B1 - Ipri

   ChSel[2] = 2; // A2 - V_SR1 / I_SR1
   ChSel[3] = 2; // A2 - V_SR1 / I_SR1

   ChSel[4] = 4; // A4 - V_SR2 / I_SR2
   ChSel[5] = 4; // A4 - V_SR2 / I_SR2

   ChSel[6] = 7; // A7 - Vout
   ChSel[7] = 7; // A7 - Vout

then are passed into the following function:

   ADC_SOC_CNF(ChSel, TrigSel, ACQPS, 17, 0); 

My question is in regard to some #defines that are used by the kit's GUI:

#define IpriR        AdcResult.ADCRESULT1 //Q12
#define V_SR1R AdcResult.ADCRESULT3 //Q12
#define V_SR2R AdcResult.ADCRESULT5 //Q12
#define I_SR1R  AdcResult.ADCRESULT3 //Q12
#define I_SR2R  AdcResult.ADCRESULT5 //Q12
#define VoutR    AdcResult.ADCRESULT7 //Q12

I can see how ADC-A7 maps to AdcResult.ADCRESULT7.

I am not sure how ADC-A2 maps to AdcResult.ADCRESULT3?

I am not sure how ADC-A4 maps to AdcResult.ADCRESULT5?

They are off by one??

I am not sure how ADC-B1 maps to AdcResult.ADCRESULT1?  I would think it would be AdcResult.ADCRESULT9?

Any clarification would be great.

Thanks,

Brent
