Re: [avr-gcc-list] eeprom usage - Measuring duration of function calls

Hi,

 

 

>An easy way to measure the duration/length of a function call is to use AVR Studio.  Set the clock speed correctly and then, using the View->Processor window combined with appropriately placed breakpoints, you can use the Stopwatch and cycle counter to measure length.

>There are a few limitations with the implementation of some eeprom and SPM type delays etc but unless you're doing significant eeprom work, this usually gives a reliable indication of runtimes.

I like AVR Studio but since my projects have been over 1000 lines or so I have got errors when trying to load the coff files into AVR Studio:

"unable to open sourcefile"  "error in coff file"

 

I haven't figured out the difference between a working coff and a non-working one yet!  Anyone else have this error?

 

cheers,
