ATMega128L Maximum Crystal Speed Thanks for you input.
I did not let out any of the "magic smoke" from the chip yet. :-)
The chip still runs and I can still communicate with it via the JTAG. I'll try running it...

Breakpoints not working as expected. I'm gonna use Johan's idea (2) as my long term solution once I get a little more AVR ASSY under my belt. For the immediate I used idea (1) to turn off optimization, debugged my...

Breakpoints not working as expected. Thanks JohanEkdahl.
Regarding turning off compiler optimization...
The Win AVR Manual says that optimization is set like this:

AVR Studio Stimuli File Thanks clawson.
I was using the "AVR Simulator 2" and the Logging and Stimuli Options don't show up. Only when you have the "AVR Simulator" does the Logging and Stimuli options...

While Statement Not Working Correctly. I totally agree!

While Statement Not Working Correctly. WOW! Thanks clawson. That was it. I unchecked M103C fuse and now it works. I'll have to read up on what that fuse does.
This is my first project with an ATMega128. It would...

AT90CAN128 Sample Code Thanks ALJ1108,
Yes, I would like to see how you setup the CAN ports, poll for incoiming messages and send out messages. If you could post you code here that would be great....

Is it OK to use macros like this? Quote:
Another thing is that it is more optimal to say
Code:
PINA & (1<<5)
OK, this is good to know. Thanks.
