The first series of single W7100 have arrived. Building a spectacular application with it. Just wait and see…. It is a pity that we have to pay so much for just shipping and handling.

Got some servos running with Arduino. The ServoShield is from www.renbotics.com and the servos from www.seeedstudio.com
The way to connect these servos is:

Red = +5 volts

Brown = GND

Orange = Signal

Connect a external powersupply to the terminal.

Made by www.pa0kn.nl an Eagle library for the iMCU7100 from Wiznet.

If you want to use your Arduino Duemilanove with Bascom-AVR and program it from within Bascom, these are the steps you could follow:

Copy avrdude.conf to the root of your PC

Put your USB Serial port on COM3 (Control panel)

Choose within Bascom an external programmer and type at programmer the path to the avrdude.exe include avrdude.exe
And at the parameters type:
-v -F -Cc:\avrdude.conf -p m328p -P com3 -c STK500v1 -b 57600 -Uflash:w:{FILE}:a

Now you can compile your Bascom-AVR program and send it right away from within Bascom.

Well it works. The wiz_reset has to be added (PORTC.3 = 3 on Arduino) and to get the right xtal you have to change in the Arduino-0017/hardware/cores/arduino/Makefile

F_CPU = 8000000
Don’t forget to put it back to 16000000 afterwards.

Very easy to control a few LEDs over the Internet with the Arduino, Ethernet Shield and a Breadboard. Have used the same pins as on the Red Bokito so it also should work on this device. On the pictures: a hardcopy of the browser-screen, a picture of the full assembly and a picture of the breadboard.

Bought an Arduino Duemilanove and an W5100 Ethernet Shield a few days back. Very nice board and a very nice development environment. Lots of examples on the Internet. Compared the Red Bokito schematics to the Arduino in combination with the Ethernet Shield and found out that there was only one pin that needed extra attention, the reset of the Wiz810MJ. So with an

Int wiz_reset = 3;
pinMode(wiz_reset,OUTPUT);
digitalWrite(wiz_reset,HIGH);

I got the Arduino ethernet software running on the Red Bokito.

Small tutorial about the iMCU7100EVB on my homepage.

Webpage with three buttons working. Can blink the three LED’s on the iMCU7100EVB-board. LED0, LED1, LED2. And my suggestion about the XRAM option is working. Instead of filling a string with the complete HTML-page, I use the XRAM. Filling about 650 bytes with the HTML-code that is send while pushing on a button. In the first 10 characters the “POST /” can be found. And at the end of the packet the LED0=0, LED1=0 or LED2=0 can be found, meaning a button has been pressed.
