Files Generated by MPLAB® Harmony v2 Configurator

Harmony Files Created After Clicking the Generate Code Button:

After using MPLAB® Harmony Configurator (MHC) to configure the Harmony Framework, click the Generate Code icon to generate the source files.


At this point, you will be asked if you want to save the current MHC configuration. If you save it, this file will be generated as <project config name>.mhc. This file captures all the selections you make in the MHC GUI.

The MHC configuration file can be shared or copied to duplicate a complete set of configuration selections.


MHC will then generate new source files based on your selections. You will be happy to know it doesn't blindly overwrite the existing source files (unless you tell it to). The Prompt Merge For All User Changes selection allows you to identify and keep any changes you may have made to source files modified by MHC. This is accomplished with the help of a merge window (diff utility) which is automatically opened for you.

Additional files may also be generated based on your Harmony Framework configuration selections.

Application and Main files:

  • app.c & app.h: Implements your application's logic
  • main.c: Contains the main() function and little else

System Configuration Files:

  • system_config.h: Defines all static build options.
  • system_definitions.h: System-wide prototypes and definitions.
  • system_init.c: Initializes all libraries, applications and processor config bits.
  • system_interrupt.c (optional): Implements all interrupt vector stubs and calls all Interrupt Service Routines (ISRs).
  • system_tasks.c: Calls all polled system logic and maintains system state.

System configuration framework files for a specific project configuration:

  • sys_clk_static.h & sys_clk_static.c: Initializes the system clocks per MHC settings.
