STMicroelectronics supports engineers in application devlopment with a wide range of development tools as well as all the embedded software components needed to take full benefit from the added value peripherals of the STM32 MCUs.
Several sophisticated toolchains are available from ST's partners, free of charge versions permit a hassle-free evaluation of the different options. Standardized embedded software components ease the kick start of the application development.
The embedded software libraries work with IAR, Keil and GCC based IDEs
Software development for STM32 made easy with STM32Cube™
STM32Cube™ is an entirely free tool, providing
STM32CubeMX , a generator of initialization C-code for STM32 MCUs, based on a graphical user interface, and one embedded software library per series of STM32 products, containing the hardware abstraction layer (HAL) 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 and HAL and Middleware library work with all STM32 compilers, the included project examples are set up for IAR, Keil, and the GCC based Atollic IDE.
STM32Cube comes with hundreds of application code examples and supports the STM32 F4, STM32 F3, STM32 F2, STM32 F0 and STM32 L0 series.
