HSC-ADC-EVALCZ + AD9272 trigger sync


Hi

I am following the steps that is on the document that I attached.

But the SPI Conteroller does not wirte the value to the board. (Every bits are 0 when I read even for the ChipID)

I activated the error massage, it shows the SPITransfer() error "The transfer bit did not get reset, Check encode". (I attached the screenshot)

Could you tell me what is the problem of write/read register function?

I am using "Octal_High_Speed_20151104_1315.bin" file for FPGA.

  • Hi Ashraf,

    The error message is gone after I changed to Synchronous mode.

    However, the register is always read as 0 value, I cannot change any vlaue of the registers. I attached the screenshot

    I tried 0~15 register addresses, all the values are read as 0. The values of all the registers are always 0 regardless I try to write any values on them.

    I tried with and without ENABLES checked, and also tried to modify the AD9272 cfg checkboxs before opening ADFPGA file, but the symptoms are same.

    I checked that SPIController is working fine with AD9272 cfg files since I could observe the filter or LNA values are reflected accordingly to the output waveform. However, ADFPGAspiR03.cfg does not write the register values.

    The attached ociloscope image is SMA1 and SMA2. (yellow, purple respectively)  I tried to change the register value both before and during running VisualAnalog.  It is not syncronizing for any cases.
