Description: 数字音频总线I2S总线规范，I2S spec，三线制-Many digital audio systems are being introduced into the consumer
audio market, including compact disc, digital audio tape, digital
sound processors, and digital TV-sound. The digital audio signals in
these systems are being processed by a number of (V)LSI ICs,
such as:
• A/D and D/A converters
• digital signal processors
• error correction for compact disc and digital recording
• digital filters
• digital input/output interfaces.
Standardized communication structures are vital for both the
equipment and the IC manufacturer, because they increase system
flexibility. To this end, we have developed the inter-IC sound (I2S)
bus – a serial link especially for digital audio.

Most of important information for running of module is available in this original document: AW_readme.txt. I describe only shortly how I made firmware upgrade under Linux:
I downloaded modified dfu-programmer from this page: https://code.google.com/p/sdr-widget/downloads/list
I installed package avr-binutils or binutils-avr according to Linux distribution.
I created this script according to manual: program-widget.
In /etc/udev/rules.d/ I created file 99-avrtools.rules according to manual. In my case was important this section:)
