You know, it is really disconcerting to do a swap on a uint8 which reads 35 in the Locals view window and have it become 50, only to realize that it is displaying in bloody decimal!
Now, I have looked and looked and looked for a way to change the display format to hex or binary. Just by accident, I discovered that command-click brings up a contextual menu with the option for hex display.
Well, bugger the fact that it changes everything, not just the line you clicked. But, on top of that, there is no option for binary!
So, how can you view binary? Any hope for some lines decimal, some hex, and some binary? Or, will I have more success with a pint of the best local brew?

The brew, and I will join you, just as soon as I am allowed to do that again.  |

I've added an Improvement request into our internal bugtracker, AVRSV-3637 for further reference |

I thought you just right clicked and said "view as hex" on the context menu - certainly the case in the generic VS2010.
EDIT: yes it's there, see picture... |

You sure about that? I just tried it and switching it (actually quite annoyingly) switches the display of everything. I'd actually like it be able to set different interpretations per item myself.
(oh and it appears to be "sticky" from one debug session to the next). |

I would go look in the Visual Studio documentation (i.e. somewhere in MSDN from Microsoft). For items in the watch window you can (or at least you could) specify how the item should be displayed by adding a specifier to the item (e.g. the name of the variable was followed by a comma and a character specifying format and stuff). This works in the watch window, so you'd have to add to that window rather than looking in locals.
Not sure if it did binary, though...
I do not have the specific documentation on this handy right now, and I have other stuff in the pipe. Come back if you could not find it and I'll have a go at locating it tonight. (And, IIRC it has even been discussed here at 'freaks before).
And Jim, the hex to binary converter is right on the top of your shoulders.. |

This is in the watch window i presume? Jim talked about the locals/autos window |

OK, I had a look. And Atmel seems to have screwed this up..
1) The documentation on how to do this in Visual Studio is e.g. here: http://msdn.microsoft.com/en-us/library/75w45ekt
2) Trying out a uint8_t variable b in Atmel Studio 6 (1863), and trying to display it as "b,x" in Atmel Studio you get this info about what is being watched: "unsigned long" and the value displayed (always zero?) does not reflect the value of the variable. Specifying ",o" for octal seems to work though (almost as good as hex - just as easy to convert to binary in your carbon-based converter).
HTH! |

You are telling me the different windows that dio the same operate differently?
EDIT: no you are wrong. The locals window operates exactly the same was the watch window and what's more the same "Hexadecimal display" option applies to both and is sticky. |

No, they should do the same. When I change to hex display, all variables are shown in hex. As I read the question, Jim wanted to change this on a per-line basis |

Specifying ,b displays in binary, at least it does on my Win7 machine. |

Windows version sould not have anything to do with this. I tried a few different format specifiers and you can see the result below. I also attached a screen shot of what it looks like when you use the context menu to shift to hexadecimal.
Results:
- The hex format specifier does not work
- The binary format specifier does not work
- The octal format specifier works
- The "Hexadecimal display" alternative in the context menu affects all items but those that have working format specifiers (i.e. octal). |

Never having used "Visual Studio" (my visual desktop programming environment is RealBasic), this is totally new to me. So, thanks for the hints. I'll give it a try.

No need. I did get the same result as you with the code you provided. You are using "b" as a variable and it seems to be (pun intended) confusing the format specifier software. Try with a variable name that is not one of the format specifiers and you will see it works. Is this considered a BUG or a Feature? |

I don't have a Visual Studio (C/C++) installation handy ATM, so I can not check if the same problem occurs there. When I get to one I will check, and if this is specific for Atmel Studio then I will consider it an Atmel Studio bug or deficiency and report it in the tracker.
OT: On the fun side - I got tired of the spell checker marking "Atmel" so I decided to add it to the dictionary. On my way there I observed that the FF spell checker suggest changing "Atmel" to "Oatmeal".  |

 My doctor has recommended that for breakfast every day, with a sprinkle of ground flax seed. Oatmeal of course, not Atmel. |

Can't figure out how to add the format specifier to the name. I click, I right-click and command-click. All over the %^^&%(&* Locals window (including the variable name). I can edit value but nowhere to add the specifier.
Enlightenment is desired.
Ugggh, OK, I can add a watch, with the variable name and format specifier. Ugly but works.

| Use the watch window and enter the variable you want to watch, a comma, and the format specifier. The locals window is handled automatically by the debugger and cannot be changed as far as I know. |

Yes - that is what I said initially. It works in the watch window. Not in the locals window, the content of which is auto-generated and not possible to edit in detail by the user.
Ugly? Not IMO. For quick debugging I can rely on e.g. the Locals window, but for any prolonged debugging work I like to set up my own watch's so that I have and see exactly what I need.
Please note that you can add a watch quickly by right-clicking the variable name anywhere in the editor and select "Add watch".
(What really sucks is that you can not re-order what you have in a watch window. That's Microsoft...). |

No, but I can carve out the internal one if someone wants it. I've commented that it may be wise to give a hint in this thread with the resolution, but this at best a "should" (not all devs have the balls to talk to you freaks )
EDIT: If you want to make a bug in the external system, then to that by all means, and just PM me with the link and I'll link it up with our internal one |

As a matter of sane user interface, I would like to suggest that a click (right click or command click) in the heading of the value column produce a contextual menu that applies to the whole column. But, a click in any individual value produce a menu that includes a value change and format selection for that particular value.

No, because looking at Microsofts documentation that does not make sense. There it says that 'h' is a

long or short prefix for: d, i, u, o, x, X

Yes, but, then there is this:

I gave it a quick try in AS6 and this is what I get on a UC3 simulator project:
Code:
int main(void)
{
volatile int a=0;
volatile unsigned char b=0;
while(1)
{
a++;
b++;
}
}
Here's my watch view:
Code:
a 3 int{registers}@R08
a,x 0x00000003 int{registers}@R08
b 2 unsigned char@0x3ffb ([R13]+3)
b,x 0x02 unsigned char@0x3ffb ([R13]+3)
b,b 2 unsigned long
b,b1 0b00000010 unsigned char@0x3ffb ([R13]+3)
a,b 2 unsigned long
a,b1 0b00000011 int{registers}@R08
a,o 000000000003 int{registers}@R08
So the modifiers seem to work with the exception of "comma b", where I had to force a size (b1) to get it to work. Will check why now...

Mistery solved:
If the expression after comma is a symbol, it will be treated as a formatting string only if it doesn't evaluate as a variable. In the latter case, comma behaves as the regular C comma operator.
We should probably change this to avoid the current confusion when people have local variables named "o", "x" or "b".
