Sharc Audio Module - USB Audio Example

This section will take you through a few examples to set up and run audio, including using the shell terminal program to interface with the application and stream audio over USB.

Hardware Setup

Follow the instructions below to set up your specific hardware variant.

ADZS-SC589-MINI

1. Power on your SAM board and plug in the 12V Power Supply to the 12V connector. If the board is properly powered, the green LED9/PWR will light up.
2. Plug the USB Micro Type B side to the SAM board USB connector and the USB Type A side to a USB connection on the PC. Note if using SAM v2.1 or greater, the USB Micro connection on the board is labeled USB OTG
3. Connect a Portable speaker or headphones to the LINE OUT connector on the SAM (ensure the speaker is turned on!).
4. Proceed to the software setup instructions (common for all hardware variants)	NA

ADZS-SC584-EZLITE

1. Power on your board and plug in the 12V Power Supply to the 12V connector. If the board is properly powered, the green PWR LED will light up.
2. Plug the USB Micro Type B side to the board USB OTG connector and the USB Type A side to a USB connection on the PC.
3. Connect the Portable speaker to the HEADPHONES connector on the board (ensure the speaker is turned on!).
4. Proceed to the software setup instructions (common for all hardware variants)	NA

Software Setup

Follow the instructions below to set up the software.

Serial Terminal Setup

This tutorial uses TeraTerm as the serial interface to your hardware.

Follow the instructions below to set up a connection to your hardware:

1. Open TeraTerm and connect to a new Serial Session, connecting to the Port labeled SC5xx Communications Port.
2. After connection, navigate to the Serial Port settings under Setup and change the Port settings to the following: Speed/Baud - 115200 Data Bits - 8-bit Stop Bits - 1 Parity - None Flow Control - None
3. With a successful connection, after reset, the terminal will display SAM Audio Starter with the version. Type help to list the available shell commands.

Audio Connection Setup

This setup will allow audio to pass from input to output through your hardware by using both an analog input source and an analog output source. This setup allows us to play audio via a USB audio source and output to a mini portable speaker.

1. In the shell terminal, type help route. The shell will display the usage for the route command.
2. In the shell terminal, type route. The shell will display the current audio routing table.
3. In the shell terminal, type route 0 usb 0 codec 0 2 20 to add to route table index 0 the audio routing of codec input to codec output with 2 channels and an attenuation of 20dB. Type route again to ensure that table was updated properly.
4. Enable audio on the USB audio source. On a Windows PC, the board will show up as “2- Audio v2.0 Device” under your Audio Devices (or something similarly named). When outputting to this device, your PC will be sending audio to the development board's OTG connector.
5. You should now be able to hear the audio from the input device coming out of the speaker connected to LINE OUT or HEADPHONES.	NA
