• RE: cf_axi_adc_core failing with -16

    Thanks Lars, that did the trick.  Looks like the answer was staring me in the face.  "mwipcore" was also being initialized to reg 43C00000. 

  • 16-bit Host Wierdness

    Ok, I am working in 16-bit mode, and trying to ge the point I am writing the firmware to the ADV212.  At the moment I have a simple loop that writes the values 0x0000 to 0x000f to the first 16 locations at address 0x00050000 in the ADV212, and then I read…

  • DMA in 16-bit area

    I would like to send data by using DMA SPORT0.
    I have no problem, if my data buffer is in the area of 32-bit variables. But when I move the buffer to area of 16-bit, DMA sends something else. Data in memory are properly arranged. I have checked it…

  • ADAU1452 and 16-bit I2S



    I am using 2 WM8804 spdif transceivers interfaced to the 1452's Serin2 and Serin3 ports and routed through the ASRCs. The input ASRCs are configured to get signal from their respective serdata input pins, and output to dsp core at Fs=48k. Once…

  • Details of the 16 bands for the ADF4351

    Hello all,

    I have a general question for the group. Does anybody have detailed information regarding the 16 overlapping bands of the 3 VCOs (sketched in figure 20 of the datasheet on page 12).  I have a system that sweeps through a range of frequencies…

  • KillThreadsInPurgatory() eats 16% of CPU


    I have 2 questions:

    1) After collecting info via Statistical Profiling for 1 hour i got strange arrangement:

    As you see, subject function got more than 16% of cycles.

    According to this thread  http://ez.analog.com/message/15851#15851,


  • iio_buffer error code -16

    Hello Team,

    We are using the iio buffer to get some samples from the FPGA. A custom IP in the FPGA pulls the valid flag on the ADC DMA for the duration of a few samples (our frame size which is 14 bytes wide) and this is read in the software using the…

  • 16-bit alternative for AD7193


    We are using AD7193 in our product for Load Cell measurement. Performance of it is quiet good. Now we are in need of a similar ADC with 16-bit resolution.

    16-bit, PGA, SPI, 50Hz rejection, decimate filters, filter word selection, offset correction…
