Michael Köcher made some fine Bascom-AVR-software, turning a Wiz200WEB module into a webserver with 8 socks, 1 for UDP remote configuration, 1 for NTP. But made also a version with one sock acting as a WebRadio. In the pictures: a Webinterface for tuning to the right station, a overview of Wiz200Web with MP3 decoder (VS1053 - bought on eBay), and a 256 Mb SD-card containing the HTML and Javascript code. And I got a chance to test it all. Difficult to make a WebRadio on a 8 bit microcontroller. The buffering is hard to do. You can check http://www.bascom-forum.de for all details.
Total overview. Wiz200Web, MP3 decoder and SD-Card.
Detail: MP3 decoder (VS1053) and SD-Card sharing the same SPI-bus.
