PCM2901: Device Driver for Vx Works

Charles Darvin

Part Number: PCM2901

Hi..all

I am using this USB AUDIO CODEC PCM2901 in a embedded system with VxWorks RTOS. I have to develop the device driver for that.

1. Any source code of Windows device driver is available?

2. How to start writing , if no base source code is available?

3. Any application notes are available? Information available in Data Sheets are not sufficient to start.

Thanks

Charles Darvin

    Hi Charles,

    All PCM29xx codec family and PCM270x DAC family are standard USB Audio Class devices. There are no drivers available as these devices are automatically recognized by the host OS.
    Perhaps you could take a look at the Audio Class interface on different OS.
