About:
Gputils is a collection of tools for the Microchip (formerly PICmicro) PIC microcontrollers. It includes the GNU PIC assembler (gpasm), linker (gplink), and object file utilities (gpdasm). The suite provides a free and open-source alternative to the proprietary MPLAB tools for developing software on 8-bit PIC architectures.

Key Features:

GNU PIC assembler (gpasm) compatible with MPASM syntax
Linker and librarian (gplink) for managing object files and archives
Object file disassembler (gpdasm) for reverse engineering and analysis
Support for various PIC12, PIC14, and PIC16 instruction sets

Use Cases:

Compiling assembly language programs for PIC microcontrollers
Linking object files into executable hex files for device programming
Analyzing existing compiled PIC firmware

Alternatives:

MPLAB X IDE – Microchip's official, proprietary IDE which includes an assembler and simulator but is significantly heavier and closed-source.
SDCC – Small Device C Compiler, which is a better choice if you prefer writing code in C rather than assembly.
