Square wave output using fmcdaq2

Dear EngineerZone community


Please support.

I am currently creating a communication system.
The concept is to generate an information signal with vc707 and output it as a Square wave from the DAC (ad 9144) of fmcdaq2. Then, the output Square wave is input to the modulator and communication is carried out.

Before that, I am trying to output a Square wave of 1 kHz (offset 0V) from DAC (AD9144) of fmcdaq2.
How can I do it?

Can you create a design as per the user guide and store a Square wave in the buffer?

I can use both Linux / no-OS.

  • Hi,

    I'm confused, ad9144 is a high speed dac (1GSPS), why do you want it to output a squarewave of 1KHz?
    The daq2 board has some filters on the output, you will have to change those to be able to transmit a sqare wave.

    Take a look at https://ez.analog.com/fpga/f/q-a/81027/daq2-kcu105-send-data-to-dac


    Are you familiar with our RF designs? If not, it may be of interest to you.

  • Thank you,Andrei

    I am sorry for confusing you.I wanted to generate a square wave of 1 kHz because the modulator used operates by inputting a square wave of about 1 kHz to 2 kHz.

    However, since the ADC/DAC I have is fmcdaq2, I would like to know haw to output a 1 kHz Square wave using fmcdaq2.

    I'm sorry. I looked at https://ez.analog.com/fpga/f/q-a/81027/daq2-kcu105-send-data-to-dac and I saw the URL and could understand changing the filter of fmcdaq2, but I could not understand which part to change specifically.

    Please tell me.

  • You have 2 options:
    Add code in hdl to generate a square wave, you can use, change directly the dds.

    Replace the sine_lut from no-Os with your own square wave.

  • Thanks for the reply, Andrei.

    Sorry for the late reply.

    I replaced sine_lut of no-Os with its own square wave as shown in attached dac_buffer.c.

    However, as a result of executing with SDK, Sin waveform was output.

  • Hi, Andrei

    After commenting out #define DMA_BUFFER 0 of L70 in fmcdaq2.c, I changed #if DMA_BUFFER in L640 to #define DMA_BUFFER and commented out from #else in L618 to #endif in L624.

    After that, I ran make with no-OS/fmcdaq2/vc 707, and as a result of running with SDK, it was displayed on the console as follows.

    How can I solve it? please teach me.

  • Hi,

    What other changes have you made to the code?

    I see:
    ../src/config.h:70:9: error: expected declaration specifiers or '...' before string constant
    printf("\nWARNING no vendor defined in config.h (for carrier)\n");
    https://github.com/analogdevicesinc/no-OS/blob/master/fmcdaq2/config.h#L69

    The in the make flow the XILINX, ZYNQ... are predefined https://github.com/analogdevicesinc/no-OS/blob/master/scripts/zynq.mk#L39

    There is something wrong with your build.

    See: https://wiki.analog.com/resources/fpga/quick_validation

    Andrei

  • Try not to use DEBUG, there will be conflicts with some xilinx files.

  • Hi,Andrei

    I changed sin_lut in dac_buffer.c and changed DMA_BUFFER in fmcdaq 2.c from 0 to 1.

    Other programs have not changed anything.

  • As mentioned above, after changing the program, I ran make again in the Linux environment.
    However, there is an error in the attached file.
    If you run make run in this state, noise will be output.
    How can I solve it?

  • Hi,

    Please post the UART messages here too.
    Some checkpoints:
    1. We have to make sure the JESD link is up. (UART messages).
    2 Use the default sine_lut table, what results do you get?
    3 Use your lut table, results?

    Andrei

  • Hi, Andrei

    I tried both of them. The results are shown below. The same error occurred in both cases.

    ⑴ default sine_lut table

    Available sampling rates:
    	1 - ADC 1000 MSPS; DAC 1000 MSPS
    	2 - ADC  500 MSPS; DAC 1000 MSPS

    	4 - ADC  600 MSPS; DAC  600 MSPS
    choose an option [default 1]:
    3 - ADC  500 MSPS; DAC  500 MSPS

    ⑵ my lut table (square)

    Available sampling rates:

  • Hi,

    Your problem starts here "xcvr_setup ERROR: XCVR initialization failed!"
    When you first started using the reference design, did it work for you?
    Have you made changes to the hardware or software regarding ad9523 or other changes that may affect the clocks in the system?
    Can you create another workspace to make sure you don't have any changes affecting the functionality?
    Is the board properly inserted in the FMC HPC1?

    Andrei

  • Hi, Andrei.

    Thank you for reply.

    As a result of debugging with SDK, referring to this question, it became as follows.

    Available sampling rates:
    	1 - ADC 1000 MSPS; DAC 1000 MSPS
    	2 - ADC  500 MSPS; DAC 1000 MSPS
    	3 - ADC  500 MSPS; DAC  500 MSPS
    	4 - ADC  600 MSPS; DAC  600 MSPS
    choose an option [default 1]:
    3 - ADC  500 MSPS; DAC  500 MSPS
    
    CPLL ENABLE
    
    CPLL ENABLE
    Tx link is enabled
    Measured Link Clock: 125 MHz
    Link status: DATA
    SYSREF captured: Yes
    Rx link is enabled
    Measured Link Clock: 125 MHz
    Link status: DATA
    SYSREF captured: Yes
    adc_setup adc core initialized (500 MHz).
    dac_setup dac core initialized (500 MHz).
    daq2: transmit data from memory
    daq2: RX capture done.
    
    

    I think that it is working properly.

    But, Looking at the output waveform it looked like the figure below.

    How can I correctly output a square wave? please tell me.

    my lut :

  • Also, is it possible to make the rectangular wave V_Low 0 V, V_High 500 mV possible?

  • What was the problem? You where using the master?

    As I mentioned in the first post, the output on the DAC goes through some filters.
    Ex looking at the board out 1 goes through T3... T12.
    Daq2 was designing for RF, high-speed data (sine waves).
    For your particular case, you have to make changes in the hardware.

  • Hi,

    I use hdl_2018_r1 for hdl and 2018_R1 for no-OS.

    I could output rectangular wave.

    However, I would like to output a rectangular wave between 1 kHz and 10 kHz.
    How can I implement it by changing fmcdaq2.c?

  • Hi,


    Again, why don't you simply use a GPIO not the daq2 for that?
    A few ideas:

    1. You can use the software to toggle a register or send/change a value at your desired frequency.
    2. Use the software to write values directly in an HDL register(that you add), in the register map, as an example see dac_data_select_s (0x4418 REG_CHAN_CNTRL_7),

    Feed it to the data select multiplexer https://github.com/analogdevicesinc/hdl/blob/hdl_2018_r1/library/axi_ad9144/axi_ad9144_channel.v#L269

    3. Write in HDL something like:

    input [31: 0] increment //from the regmap

    reg [15:0] square_wave = 0;


    always @(pesedge clk) begin
       sawtooth_wave <= sawtooth_wave + increment;

       square_wave <= {16{sawtooth_wave[31]}}
    end

    The frequency of your square wave is core _clock/(2^32 * increment)
    use the above to calculate the value for increment.

    https://en.wikipedia.org/wiki/Numerically_controlled_oscillator

    You get the idea, output that trough the multiplexer mentioned above.
