I'm using arduino-0018.

Anyone knows what should i do to let me program Atmega16 using Arduino(0018)?

Thanks.

Up to now,follow http://www.subtours.com/ralph/theory/atmega16witharduino.html this article,i'v modified pins_arduino.c in arduino-0018\hardware\arduino\cores\arduino\

Can't pass the compile...
Can anyone give me some advice on what i need to do?

Thank you very much.

Can't pass the compile

What error does it give?

[Reply #4 on:]

That's correct - the ATMega16 doesn't have either EICRA or EIMSK.

[Reply #5 on:]

so which file should i modify to make it work?
WInterrupts.c or there is another file made this happen?
Thanks.

[Reply #6 on:]

You may get away with just modifying "WInterrupts.c" where EICRA is defined as MCUCR and EIMSK as GICR for the ATmega8.

[Reply #7 on:]

I modify all the necessary files and pass the compile but I con not
down load the hex to the mcu

[Reply #8 on:]

I used the parallel programmer and it work fine


how can I attach files here ??

[Reply #9 on:]

I'm currently working on a Sure-Electronics ATMEGA16 based board and would like to run Arduino on it. Could you post the files you've changed onto this forum please? I'd be very grateful.

...ATmega16 is listed as working.
