News

PMP V1.3.22.43 released - by PPA 2009.08.06 2:04 PM

This is a maintenance version. See download page for details - here.

Some very important information that is not yet in the documentation:

This is the first release that tries to be compatible with the new MPLAB linker generic scripts.
MPLAB V8.30 is the last version that has both old scripts and new scripts, so keep this version until you have tried all the debug options that you need, after you may try V8.33 if you really need it.

So what PMP handles in the new generic scripts?
There is a new checkbox option in the project's options linker tab to validate or not the use of new scripts. If not checked (default), old scripts are used.
The _DEBUG symbol is now defined for the linker if you compile with the "debug mode".
For most scripts, this is enough but not for scripts that need other linker conditionals.
So a new $DEFINE syntax has been defined to allow linker defines to be declared in your main source file: {$DEFINE <Symbol> <Expression>} where <Symbol> is a symbol starting with an underscore and <Expression> may be any expression that uses literals and other underscored linker symbols.
For example:
{$DEFINE _DEBUGCODESTART $3F00}
Only symbols starting with an underscore that have a value are sent to the linker.

Since I have not the necessary hardware to check all the possibilities, please feel free to report any trouble and unsupported special case.

GPUTILS support is also in progress but it will come later, there's still some work (I'm working to a new .xml based generic device file format that should replace both .inc and .dev files, but it will need to be maintained in parallel with MPLAB files, so the automatic compatibility is compromised... Well, I have to think about it.
