Peux tu faire une sortie des variables d'environnement
As tu lu ca http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1183303612

C'est pas mal de boulot de porter le code de l'arduino sur un autre microprocesseur...(c'est faisable mais pas très intéressant).
Tu as déja dépassé les capacités du 168 en flash ou en ram ?
Une bonne solution peut etre de réécrire le code ou de s'interfacer avec de la ram externe (meme si j'ai pas trouvé grand monde ayant déja fait ca).

Tout va en RAM si tu ne précises pas explicitement que ça doit etre stocké autre part.
Si tu parles US essaye ca : http://www.arduino.cc/en/Reference/PROGMEM

je pense que tu compares des pointeurs la, pas les valeurs

essaye ca :

#include <string.h>

if(strcmp(serInString,"SYNTAX ERROR")==0)

Hi,

There was a bug in the dapa defintion for the atmega168 (extended fuse not supported => disable bootloader) in uisp.
I send a patch on the uisp forum http://savannah.nongnu.org/file/uisp-20050207-m168-stk500-extendedFuseSupport.patch?file_id=11573

So you will have to recompile (or I can send you a compiled version for windows).

Anyway, try to burn a "hello world" sketch (blink led) with the dapa and the buggy uisp version you have, this will work (because you do not use the bootloader this way).

did you put Vcc (+5 V) on the top right pin of the texas instrument chip (bottom chip)

VCC on ti chip ?

glad we're pretty much getting to the same result.
4 questions:
- i saw you set a 115.2 Kbaud rate on the uart, is that causing a problem with a 16Mhz crystal (according to p162 of m8 datasheet, that's a 3.5% error)?
- did you manage to flash the bootloader on m168 with the 16MHz crystal and avr studio?
- i saw in test.ccommand that you're using uisp to flash with stk500v2, did you manage to flash the m168 with uisp and stk500v2 on the 16Mhz crystal?
- are you planning to work on the bit bang (as it is better just to do it one time  smiley-wink ) ?
 
Regards

3. Could i use the Arduino to burn my programm on an empty atmel or do i need another programmer for the task?

Buy a programmer.

You can try this http://www.uchobby.com/index.php/2007/11/04/arduino-avr-in-system-programmer-isp/
in order to turn your arduino into a programmer (I did not try it)

There is something like this for Linux http://www.intra2net.com/de/produkte/opensource/ftdi/index.php
I tried it with my Ubuntu FF box and I can read the serial number.
I did not try the flash command but it might work.
Don't know if it works under OS-X

I think that's a good place to start from http://www.arduino.cc/en/Main/StandaloneAssembly
Removing serial and power parts is clear.

an ftdi-to-midi driver would be far more useful to me
kuk

As a digging Linux user I never find something like this. So I'm not sure this will happen in the next few months.
I hope I'm wrong.

The baud rate aliasing I was referring to allow you to use the arduino
serial monitor to display 31250 bps (choosing the bps you decided to
customise let say 38400 for example because it is rarely used).

I do not have a Mac box but I wonder if it is possible to use ftdi sio
linux driver under mac

Depends of your box.
I can see 31250bps datas coming from my arduino with my linux box (thank U open world  smiley ).
If you are linux aware have a look at http://ftdi-usb-sio.sourceforge.net/ (Non standard baudrates)

I did it with a 4N35.

I spent a lot of time trying to get it work 'til I understand that the midi connector was reversed.
Try to wire it rear and face view as Kuk explained
