Hmmm. ... Can you set a "variable watch" that triggers on a memory value that should not change but IS getting changed? I don't remember if Studio has that. Another possibility is that you are getting a corrupted stack (ie, unmatched push/pops or something that writes into area u

I added a full vector table, and every entry for the unused ints sets "sanity_flag" to some unique value. There's a task that checks sanity flag for any non-zero value, and it's never triggering.

I notice that just before the crash you are setting the device pinb5 to an output pin, is the pull up enabled when set as an input ? Might be an idea to insert an intermediate state, might possibly be getting a vcc to 0v power short, (see section 12.2.3 int the datasheet) this co

Is there something unusual I should know with this device? I'm watching it step through a simple routine to light some LEDs, and after stepping through a single CBI instruction it's telling me that half of SRAM has been changed.. There are four alarm timers, and if any of them is

Without getting into the OS "war" I have a fuse question. AVR Studio uses GCC and of course it can also be used as a command line tool along with avrdude, etc. Is there any universal way to specify the fuse settings you want within the C source code and have it picked up by the p

Frankly, I just think that no one has ever gone through the bother of doing one. In the ARM world you are a woosie for not doing everything the hard way - Which is one of the reasons I haven't gotten very far in the ARM world I guess. Windows has some good tools, but nothing ever

But the GUI was written for Windows. I'm considering a GUI that is more universal, say JAVA or Python. Anything would help! Avrdude is a good tool, but as you say it is SO 20th century! DLC John Samperi wrote: > At 05:46 AM 26/03/2009, you wrote: >> avrdude which is a CLI tool. >
