Specifying the MPLAB® Harmony Framework Path
When you create a new MPLAB® Harmony project, you are required to specify the location of the Harmony Framework you want to use (e.g., C:/Microchip/harmony/v2_05_01). This lets the compiler know where all the framework source files are.
If you want to change the framework path for an existing Harmony project (possibly to move the project to an updated version), the MPLAB Harmony Configurator (MHC) can help you.
Click on the Harmony Framework Configuration icon at the top of the MHC window.
Click on the folder beside the text box, and browse to the new path you want to use.
