Dagu Magician Arduino Compatible Controller Board

As long as I'm waiting for the delivery of my Arduino UNO board, I have a "Dagu Magician Arduino Compatible Controller Board" bought low.
The instructions can be found here ... DAGU Board Manual
But I do not know on what kind of board I should put the Arduino IDE.
The board operates one ATMega8.

Has anyone ever used this board and programmed? I would appreciate help.

AhhHa! Atmega8l-8pu

Hello! I recently got a new Atmega8l-8pu chip and I have the Mr. General robot. Will the Atmega8l-8pu chip substitute in place of the Atmega8A chip? I looked up the Datatsheet and the pinouts are the same. Before I tried it I thought that I would inqure first.

Thanks! Low Battery

Arduino "Tone" command and the ATmega8 - it just won't work

Recently Frits pointed out that sound was used much with robots on this site. I agree and am trying to add sound to a miniature bi-ped robot I am designing. I am now using an ATmega8A processor set up as an Arduino and recently tried using the tone command with strange results. I only get a few frequencies. The digital oscilloscope shows that I am only getting 5 frequencies  which I guess change when the timers prescaler is changed. These frequencies are:

61Hz, 244Hz, 976Hz, 3.9KHz and 31.2KHz

Cheap and small swarmbots

So. I'm finally building swarmbots. My goal is to have bot that is small (should be 25mm x 25mm, will be ~30mmx30mm) and cheap (less than 50$ per one. even when building only one).

 

 

interface with atmega8 with parallel port

Does anybody of LMR knows how to for example turn port D0 on the atmega8 with the pc linked to the atmega8?

For example when I start this program the atmega8 turns on port D0 and when I turn an other program on port D1 turns on.

Which program do I need and what circuit do I need?

Can somebody give me an example program?

Please

 

 

Thanks

servo.h library file for Atmega8?

I bought MicroCamp Mega8 robot kit. Currently I am trying to add a servo motor on this MicroCamp Mega8 Controller Board. But I have a problem that I don't know how to write program to control the servo motor. Can anyone help me?

In fact I need a header file called servo.h for the MicroCamp Mega8 board. It uses 'C' programming language and Atmel Atmega8 microcontroller.
