TSW1400EVM: Examples Matlab code for Read/Write_Registers

Part Number: TSW1400EVM

Hi,

I'm using a TSW1400EVM to capture data from an AFE5818EVM. I found HSDCPro_Matlab_Example and able to run "HSDCPro_Automation_DLL_ADC_Example_64bit" without error. However the ADC result is not correct.

I assumed that it is because there is no initialization to the AFE-registers done in this example, and I have to set the values for AFE-registers myself using "Read_Registers" and "Write_Registers" DLL functions. Unfortuantely I couldn't get them to work and also I didn't find any example for these "Read/Write_Registers" DLL function.

Is my assumption correct? and is there any Matlab example shows how to use DLL "Read/Write_Registers" (I found the HSDCPro DLL Automation documentation, but still can't run them properly) ?

Thanks,

Bien

    Bien,

    The automation for HSDC Pro is only used for controlling HSDC Pro.  The programming of the AFE still needs to be handled by the AFE GUI. 

    The Read/Write DLL functions you are referring to are only used to communicate to the connected EVM, in this case the TSW1400EVM.

    Hi Ken,

    Ok, I get it now. So the initialization of AFE module can only be done via either AFE-GUI or SPI right ?
    Is there DLL functions or Matlab-Script for controlling the AFE GUI ?

    Thanks,
    Bien

    Bien,

    There does exist a way to use matlab to connect to the USB chipset and perform a write and read to the SPI bus. However I will defer to this device apps team to support that function. I will make them aware of your need and let them respond.

    Hi Bien,

    We currently only support using the HMC-DAQ GUI to perform reads/writes to the device via SPI. Some of our customers do use external microcontrollers or FPGAs to communicate with the device on our EVM via SPI.

    Sincerely,

    Hi Ken, Olu
    Thanks for the information. Then we'll try to access the AFE registers via an external microtroller.

    Best regards,
    Bien
