Main features
STM32CubeProgrammes offer a unified, cross-platform programming environment for all STM32 devices. It supports GUI, CLI, and C API interfaces for manual use, automation, and custom tool development.
- Erasing and Programming
- Memory and File Editing
- Option Bytes
- Security
- Registers
Smart and automatic programming
Erase, program, and verify internal and external flash memories from a single interface. Supports full or partial chip erase, with configurable manual and automated workflows.
Low-Level memory access
Directly read, edit, and extract STM32 memory for in-place testing and analysis without firmware rebuild.
STM32 option bytes configuration
Inspect and modify STM32 device settings, with dual views, clear descriptions, and one-click factory reset to the default state.
Device security made easy
A clear interface to manage security features through all device's states
Real-time access to chip registers
Real-time register monitoring, editing, and logging for IDE-less debugging and validation.
