[Ovmsdev] PICkit changes parameters (EEPROM)

[Michael Balzer]

Tom,

that could be the case if it's only me, but this has been reported by 
other users as well.

This is my PICkit config:

       <PICkit2PlatformTool>
         <property key="pk2settings.3state" value="false"/>
         <property key="pk2settings.preserveee" value="true"/>
         <property key="pk2settings.setvddvoltage" value="5,00"/>
         <property key="pk2settings.userpgmexec" value="true"/>
         <property key="pk2settings.usetargetpower" value="false"/>
       </PICkit2PlatformTool>

The "5.00 V" setting is marked red with "!!" and "Unknown cause" by the 
MPLAB config UI -- I don't know what that means.

Regards,
Michael
