Snazzier "Memory Usage Report" output

Because space is at a premium I am always experimenting with different ways of coding things to see which turns out smallest. The option to output the size information ("Memory Usage Report") at the end of the compile is nice but what would be even cooler would be to have a panel in visual studio which shows this information a little nicer like this for example:


This shows the output of `avr-objdump.exe -t (outputfile)` in a treeview so you can see how much space individual functions and data items are taking. The gray color indicates that the value is in BSS instead of initialized data, and of course this could look a little more polished. This is just a few minutes of throwing together an idea.

Quick and dirty source code PasteBin. Copyright "No rights reserved, free to use"

EDIT: Uses the TreeView with Columns control

That's excellent I can use that. maybe I should add it to the "Micro Explorer" as an option that you can run at any time after first compile.   

The std VS output windows are text only and I don't think you want it after every compile so moving it to the micro explorer is better?

I compared your Process code to mine and I had a .WaitForExit and was also attempting to RedirectStandardError. Dis-assembly works instantly now so will apply the same to other functions that use a Process as soon as I have time to test the changes.

Thanks very much for this.

The Tree View Columns project is also cool!

While you are looking at the Micro Explorer, how about adding a refresh function to it. If   you install new libraries, the ME does not pick it up.

@Marius thanks for reminding me I knew that and forgot.

Can anyone tell me the difference between avr-size.exe and avr-objdump.exe? I'm using avr-size on the HEX at the moment to get the memory info. CapnBry is using avr-objdump

CapnBry, should i change it over?

The difference is that avr-objdump only reports named symbols in the elf, you'll notice there's a discrepency between the text size reported in my demo and what what avr-size reports. For some reason avr-objdump also doesn't report the size of things which are just labels, e.g. the 100 byte vector table, or the static constructor area, bss and data initialization functions. The avr-size accurately represents what is going to be uploaded to the microcontroller because it just looks at where things end. My code also should include the size of data segment data in the progmem count, on account of them also residing in the program memory flash area.

How can I add this view this on VS2012?

- specifically the function and variable size breakdown ( the disassembly view is too large to go through to find memory size culprits )

I create new project for this utility on the github.
You may download binaries and source here:
