6.1.1 Project Format Supporting Packs
The project format in MPLAB X IDE v5.xx and greater supports packs which contain versioned device and tool information. Packs can be found under <MPLAB X IDE install directory>\vx.xx\packs where vx.xx is version 5.xx or greater.
Managing Projects
Projects created in or updated to v5.00 or greater are not backward compatible to v4.xx.
When you open a project created prior to v5.00, a message displays, announcing that it will upgrade the project to the current project version.
- If you choose Yes, the project will be upgraded to the current version and the project can no longer be opened with the earlier version of the IDE.
- If you choose No, you cannot save any modifications to the project in v5.00 or greater. You must make any changes in v4.xx.
If you upgraded a project to v5.xx but need to revert a project back to v4.xx, install the plugin in MPLAB X IDE found under . Once that plugin is installed, you can save your project in the older version by selecting .
Packs Implementation
Previously (v4.20 and earlier versions), supported device information was built into each MPLAB X IDE version. You could not update the devices supported in this version; you had to wait until the next MPLAB X IDE version for device support.
Now (v5.00 and latest versions), this information for each device is grouped into versioned packs, so you can obtain new device support without updating your MPLAB X IDE version.
