  1. I am currently trying to setup the ssm2603 audio codex on the zybo board to output audio, with a purely rtl design. I am having issues setting up the audio codex via i2c. I am wondering about how you should send the address information to the audio codex to initialize the setup registers. Below is an RTL state machine of how I am trying to write the register values to the codex. Can someone verify that this is the correct way to address the registers? I am unable to get anything out from the audio codex currently, and I don't think my initialization is working. always @(*) be

    Zybo DMA example

    I downloaded the ZYBO-master from the github, and ran the tcl script from the following directory: C:\Zynq_Book\ZYBO-master\ZYBO-master\Projects\dma\proj. Could the tcl files have been mixed up or misplaced? Has anyone fIgured out how to fix this? this is the error that I get: ERROR: [IP_Flow 19-3461] Value 'hdmi_in_ddc' is out of the range for parameter 'IIC Board Interface(IIC_BOARD_INTERFACE)' for BD Cell 'axi_iic_0' . Valid values are - Custom INFO: [IP_Flow 19-3438] Customization errors found on 'axi_iic_0'. Restoring to previous valid configuration. INFO: [Co

    zybo audio

    I have the same problem. I downloaded the ZYBO-master from the github as well, and ran the tcl script from the following directory: C:\Zynq_Book\ZYBO-master\ZYBO-master\Projects\dma\proj.

  4. UPDATE: So far I have still not been able to figure out how to get the PMOD MIC3 to output throught the Audio Codec. Background: for a little more background on this Project, I am trying to do a basic version of Acoustic Beamforming. To do this I will create a custom verilog design that will take audio samples from multiple MIC3s and store them in a large buffer array. Then I am planning on applying some digital filters on the samples in the ARM processor, and ultimately output a single audio stream through the I2S Audio Codec. I have included the code for the multiple Mic audio interfac
  5. Awesome thanks! I will let you know how it goes.
  6. I recently purchased the Zybo, zynq development board, along with a MIC3 so that I could hopefully take in audio from the PMOD port and then process it in Arm processor, and finally output it through the audio output port. I'm having trouble getting the audio routed with the IP in vivado. I'm fairly new to the vivado IP integrator but I have some experience creating verilog projects. Has anyone used the MIC3 with the zybo, or know how to get the audio from a MIC3 in one of the PMOD ports, into the ARM for proccessing? Any help would be greatly appreciated.
