Ethernet working…

Saturday, October 9th, 2010

No evenings trying to get things running, just connect a RJ45 with magnetics to the mBed, compile an ethernetexample from the cloud, and the mBed is running as a webserver. Used a Magjack 08B0-1X1T-06-F, downloaded the datasheet and connected RD+/-, TD+/- TCT and RCT and things are up and running.

Wiz200WebRadio

Wednesday, October 6th, 2010

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.

Got an email from Tomaz. He has seen the Arduino Mega 9DOF with Bluetooth and asked for the BTM-112 and BTM-220 library for Eagle. Well here they are.

Got my NXP box with the LPC1768. Looks like the big brother of the Arduino Nano 3.0.
