-===== Description ===== 
- 
-This demo contains a Vivado IP Integrator project and Vitis projects that control the Zybo Z7's audio codec in order to record and play back audio  
- 
-The audio demo records a 5 second sample from microphone(J6) or line in (J7) and plays it back on headphone out (J5). Recording and playback are started by push buttons. Messages are printed to a connected serial terminal that provide information on the status of the application. 
- 
-Additional information on how this demo can be used can be found in appropriate READMEs, linked below. 
- 
----- 
-===== Inventory ===== 
- 
-  * Zybo Z7 with a MicroUSB Programming Cable 
-  * Vivado and Vitis installations compatible with the latest release of this demo (2020.1) 
-    * //See [[programmable-logic:guides:installation|Installing Vivado, Vitis, and Digilent Board Files]] for installation instructions.// 
-  * Serial Terminal application to receive messages printed by the demo 
-    * //See [[programmable-logic:guides:serial-terminals:start]] for more information.// 
-  * Headphones or Speakers 
-  * Audio Input Device - such as a microphone or computer with 3.5mm audio jack, etc

-===== Download and Usage Instructions ===== 
- 
-First and foremost, releases - consisting of a set of files for download - are only compatible with a specific version of the Xilinx tools, as specified in the name of the release (referred to as a //release tag//). In addition, releases are only compatible with the specified variant of the board. For example, a release tagged "20/DMA/2020.1" for the Zybo Z7 is only to be used with the -20 variant of the board and Xilinx tools (Vivado and Vitis) version 2020.1. 
- 
-The latest release version for this demo is highlighted in green. 
- 
-**Note:** //Releases for FPGA demos from before 2020.1 used a different git structure, and used a different release tag naming scheme.//

-Plug the Zybo Z7 into the computer via the microUSB programming cable. 
- 
-Plug in your microphone or aux input into the appropriate jack on your Zybo (MIC IN or LINE IN, respectively). Plug your speakers/headphones into the headphone jack (HPH OUT).

-At this point, the demo is now running on your board. Refer to the [[#description|Description]] section of this document for more information on what it does. 
----- 
-Additional steps beyond here present how you can use the other archive provided in the release, containing the hardware project, to rebuild the Vivado project, and use a newly exported XSA file to update the platform in Vitis.

-==== Controls ==== 
- 
-Audio playback and recording are controlled by push buttons as below. 
- 
-^  Button  ^  Function             ^ 
-^  BTN0    |  no effect            | 
-^  BTN1    |  record from mic in   | 
-^  BTN2    |  play on hph out      | 
-^  BTN3    |  record from line in  | 
- 
-=== Recording from an Input === 
- 
-To record from MIC IN, press **BTN1**. To record from LINE IN, press **BTN3**. Once the recording is activated, the message "Start Recording..." will be sent over UART and the demo will record 5 seconds of audio. If any buttons are pressed during the recording, the message "Still Recording..." will be sent over UART. 
----- 
-=== Playing to an Output === 
- 
-To play to HPH OUT, press **BTN2**. Once the playback is activated, the message "Start Playback..." will be sent over UART and the demo will play 5 seconds of audio. If any buttons are pressed during the playback, the message "Still Playing..." will be sent over UART. 
- 
----- 
-===== Additional Resources ===== 
- 
-All materials related to the use of the Zybo Z7 can be found on its [[..:start|Resource Center]]. 
- 
-For a walkthrough of the process of creating a simple baremetal software project in Vivado and Vitis, see [[programmable-logic:guides:getting-started-with-ipi]]. Information on important parts of the GUIs, and indirect discussion of the steps required to modify, rebuild, and run this demo in hardware can also be found here.
