Low level drivers, hardware abstraction layers, and middleware like RTOS, USB stacks, graphic stacks, are indispensable bricks for a fast and efficient application development.

For the STM32, ST proposes a large range of embedded software components including  

  • Audio (MP3, WMA, Voice, ...)
  • Connectivity (USB, TCP/IP, Bluetooth, Zigbee RF4CE, ...)
  • Graphical Interfaces
  • Cryptography (Free STM32 Library with public key, symetric and hash algorithms),
  • Motor Control and Safety (IEC 61508 SIL for industrial, 60335/60730 Class B for Home Appliance)

These components are either developed by ST or supplied, ST's partner network or stem from open source initiatives. 

With the STM32Cube ST follows a new route for embedded software by integrating low level and middleware software in one library and by supplying a configuration tool, capable of generating initialization code for the application. 

Initialization code generator and software libary

Software development for STM32 made easy with STM32Cube

STMCube™ is an STMicroelectronics original initiative to make developers’ lives easier by reducing development effort, time and cost. STM32Cube is the implementation of STMCube that covers the whole STM32 portfolio and provides:

STM32CubeMX, available under Windows®, Linux® and macOS® is a tool able to generate initialization C-code for STM32 MCUs based on a graphical user interface and one embedded software library (Cube Embedded Software package) per series of STM32 products. This embedded software library comprises the hardware abstraction layer (HAL) and Low-Layer (LL) APIs for the STM32 peripherals and a set of Middleware (RTOS, USB, TCP/IP, Graphics, …) based on components that are either ST developed or open source.

The initialization code, Middleware libraries, HAL and LL APIs, are all compatible with every STM32 compilers. The included example projects are set up for IAR, Keil, and the GCC-based AC6 SW4STM32.

STM32Cube comes with hundreds of application code examples and supports all the STM32 series.
