2. Evaluation Board Usage Instructions¶
Installing Windows Driver¶
Note
- Upon receiving the evaluation board, if this is your first time using it and you are on a Windows system, you need to install the Windows driver before conducting evaluation tests.
- Windows 10 build 1809 and later versions have native USB UAC 2.0 drivers. However, the native driver can only play audio at sampling rates up to 384Khz. To evaluate 768Khz sampling rates and DSD format, you need to install a third-party driver.
- Linux, Mac, and mobile devices do not require driver installation
-
Download evaluation version driver. After extracting, run XMOS_TUSBAudio_eval_v5.58.0_2023-06-29_setup.exe directly and follow the default installation process.
-
Connect the evaluation board to the Windows computer via USB cable. Click on the TUSB icon in the lower right corner. If the USB Audio Device displays as shown in the figure, the driver is running normally.
-
The evaluation board enumerates as USB 2.0 Audio Devices (UAC2.0) in Device Manager
-
In the playback tab, set USB 2.0 Audio Devices (UAC2.0) as the default device
Audio Evaluation¶
The evaluation board has 3 indicator lights: USB, OPT, COX, representing USB, optical, and coaxial modes respectively.
- Short press MODE button, USB indicator lights up, plays USB audio.
- Short press MODE button, OPT indicator lights up, plays OPT audio.
- Short press MODE button, COX indicator lights up, plays COX audio.
