How to acquire data from few channels with AD8285CP-EBZ and HSC-ADC-EVALCZ board?

Devices: ADC - AD8285CP-EBZ, Data capture - HSC-ADC-EVALCZ.

Hi! I'm trying to write MATALB program for data capture in our automotive radar project using HadBoardApi. I've found few examples for one-channel acqisition, but I can't scale that code for multiple chanels. Can you show me how to do that please?

Here is example of my code:

clear variables

MyHadBoardApi = NET.addAssembly('C:\Program Files (x86)\Analog Devices\VisualAnalog\HadBoardApi.dll');

HadBoardApi.HadBoard.FindBoards();

if (HadBoardApi.HadBoard.BoardCount)
disp('Board Found!')
else
disp('Board NOT Found!')
end

fpgaFilePath = 'C:\Program Files (x86)\Analog Devices\VisualAnalog\Hardware\HSC_ADC_EVALC\AD8283.bin';
HadBoardApi.HadBoard.Board.ConfigureFpga(fpgaFilePath);
disp('FPGA Programmed!')

%% Configure ADC/FPGA SPI Registers:
%[reg_addrs, reg_values]=AD9625_parseXML('C:\ProgramData\Analog Devices\SPIController\Cfgs\ad8283.cal');
HadBoardApi.HadBoard.Board.SpiInitInterface(1,HadBoardApi.HadSpiParameters(1,0,1));
%HadBoardApi.HadBoard.Board.SpiWrite(reg_addrs, reg_values);
%HadBoardApi.HadBoard.Board.SpiWrite(int16(hex2dec('00')), bin2dec('01111110'));
HadBoardApi.HadBoard.Board.SpiWrite(int16(hex2dec('05')), bin2dec('00001111'));
HadBoardApi.HadBoard.Board.SpiWrite(int16(hex2dec('0C')), bin2dec('00000010'));
%HadBoardApi.HadBoard.Board.SpiWrite(int16(hex2dec('0D')), bin2dec('01000001'));
%HadBoardApi.HadBoard.Board.SpiWrite(int16(hex2dec('0F')), bin2dec('01111100'));
HadBoardApi.HadBoard.Board.SpiWrite(int16(hex2dec('2C')), bin2dec('00000000'));
HadBoardApi.HadBoard.Board.SpiWrite(int16(hex2dec('FF')), bin2dec('00000001'));

HadBoardApi.HadBoard.Board.FpgaSpiWrite(uint16([288;289;292]),uint16([135;7;31]));
if (HadBoardApi.HadBoard.Board.SpiRead(int16(10)))
disp('PLL Locked');
else
disp('PLL NOT Locked');
end
if (HadBoardApi.HadBoard.Board.SpiRead(int16(20)))
disp('Twos Complement');
else
disp('offset binary')
end
%% Get Data From ADC:
DataLength = int32(2^10);
HadBoardApi.HadBoard.Board.FillFifos (DataLength, 30);
if (uint16(HadBoardApi.HadBoard.Board.FpgaSpiRead(uint16(330)))==16)
HadBoardApi.HadBoard.Board.FpgaSpiWrite(uint16(320),uint16(3));
else
ADC_Data1 = HadBoardApi.HadBoard.Board.CaptureFifoWords (DataLength, 0);
%ADC_Data2 = HadBoardApi.HadBoard.Board.CaptureFifoWords (DataLength, 1);
end
u1 = (double(uint16(ADC_Data1))-32768);
u2 = mod(u1,16);
%u1(2,:)=((double(uint16(ADC_Data2))-32767)./32767);
%u2 = u1 - mean(u1);
plot(u1);
%plot(abs(fft(u1)));

In this case I get same data for two channels, but there are two different signals from two generators on the ADC board.

This code is result of compilation of examples from this site. I feel lack of uderstanding how this code works because i can't find  any documentation for HadBoardApi, but i've seen several mentions of some .chm file. Can you give a link to this file or any other docs please?

Thanks a lot.
