For a PIC16F887 project with 2KB of code, Free mode works fine. For a PIC18F47Q43 with 128KB and heavy math, Free mode might generate 15-20% larger code than Pro. However, for 90% of hobbyists and students, v2.05 Free is perfectly sufficient .
The is an optimizing C compiler for 8-bit PIC and AVR microcontrollers that can be downloaded and used for free as an unlicensed product. Version 2.05, released on December 20, 2018, was a significant update that introduced expanded optimization levels for free users and migrated the macOS version to a 64-bit application.

For embedded systems engineers and hobbyists working with Microchip’s 8-bit PIC microcontrollers, the is an indispensable tool. It translates your C code into machine language that PIC chips can execute. Among the various versions released, v2.05 holds a special place for many developers due to its stability, feature set, and compatibility with older projects. For a PIC16F887 project with 2KB of code,
: The MPASM assembler is included directly in the XC8 compiler installer rather than being a separate part of the MPLAB X IDE. The is an optimizing C compiler for 8-bit
Supports Windows, Linux, and macOS (though see compatibility notes below). Key Features in v2.05
: The compiler defaults to the C99 language standard for new projects, though it maintains legacy C90 support for older PIC projects. Microchip Technology Downloading and Installing the Free Version
