Some interaction now on the TuxGraphics-board. LED can be switched on and off through UDP and TCP (HTTP). Think the tutorial is finished now. Will be entering the Circuit Cellar contest with another ethernetcontroller, the WizNet W5100. Have done some work on the WizNet W3100 but the W5100 is new to me. Also busy with http://www.pa0kn.nl with a USB version of the DRM-receiver. Later more…
Took me some time but got the TCP and HTTP working on the TuxGraphics board. A small HTML-page with a picture from the outside world. Have to optimize the code, lots of repeated code that can be put in a subroutine. SRAM of the Atmega168 full, perhaps have to do some variables-optimize too. Now time to put some action on the HTML-page like a switch or a LED. Got some nice boards from a Maas coffee-machine with I2c like PCF8583 RTC, 2 x PCF8574, four relais and six opto-coupled inputs. And even a buzzer.
First real application working on the Tuxgraphics-board. UDP User Datagram Protocol. Used the EDTP Internet Test Panel for it. Every typed character is returned. Going to extend the UDP-routine so a LM76 temperature-sensor can be read over the Internet.
