New Software from STMicroelectronics Makes Designing with STM32
Microcontrollers Even Easier, Faster, and More Accessible

  Powerful new STM32Cube(TM) software platform comprising tools, middleware,
    and Hardware Abstraction Layer allows customers to focus on innovation

GENEVA, Feb. 20, 2014 (GLOBE NEWSWIRE) -- STMicroelectronics (NYSE:STM), a
global semiconductor leader serving customers across the spectrum of
electronics applications, and a leader in ARM^® Cortex^®-M-core based
microcontrollers, is introducing STM32Cube^TM, a powerful new free design tool
and software for its STM32 microcontroller portfolio. This new development
platform, which simplifies and accelerates customers' projects, is set to
further enhance the position of STM32 as the go-to microcontroller family for
innovative electronic designers.

The new STM32Cube(TM) development platform comprises the STM32CubeMX graphical
configurator and initialization C-code generator that provides step-by-step
guidance for users and a set of rich embedded-software components that save
integrating software from multiple sources. The software includes a new
Hardware Abstraction Layer (HAL) that simplifies porting from one STM32 device
to another. By gathering all the generic software components needed for
developing applications on STM32 microcontrollers into one single package,
this platform eliminates the complex task of assessing dependencies between
individual software components. STM32Cube provides hundreds of usage examples
and an update mechanism for fast and efficient access to the latest versions
of the software.

"STM32Cube allows engineers to take maximum advantage of our large STM32
portfolio, which now extends to over 360 microcontrollers, offering extensive
hardware and software compatibility spanning a wide range of performance,
power, and features," said Michel Buffa, General Manager, Microcontroller
Division, STMicroelectronics. "Today we are announcing the graphical
configuration tool, with the middleware and HAL supporting high-performance
STM32 F4 devices. Further releases will roll out during 2014, extending
support to all STM32 devices."

Further Technical Information:

The STM32CubeMX graphical configuration tool simplifies and automates
configuration and generation of STM32 initialization C code ready to be used
with several development environments. STM32CubeMX is also available as an
Eclipse plug-in, allowing use within Eclipse-based development environments.
The tool provides an easy-to-use filter for selecting the desired STM32 device
and graphical wizards to simplify configuration: the pin-out wizard assists
pin assignment to avoid conflicts, embedding a powerful constraints solver;
the clock-tree wizard assigns clocks and performs dynamic validation; the
peripherals-and-middleware wizard aids configuration to avoid unusable
settings; and the power-consumption wizard checks that the application meets
the available power budget.

The new HAL, part of the STM32CubeF4 embedded software, offers a high
abstraction level, hence simplifying the porting of an application from one
STM32 microcontroller to another. Features include support for re-entrant APIs
allowing use with an RTOS, extra function calls allowing developers to target
specific peripheral features and thereby leverage the rich functionality of
STM32 microcontrollers, and support for polling, interrupt, and DMA (Direct
Memory Access) programming models. The HAL uses the industry-standard
CodeSonar^® static-analysis tool, which helps ensure safe and predictable
behavior of customer applications, and is distributed under a non-restrictive
BSD (Berkeley Software Distribution) open-source license.

The STM32CubeF4 middleware, part of STM32CubeF4 embedded software, also
announced today for STM32 F4 series microcontrollers includes a TCP/IP stack,
a full USB Host and Device stack supporting multiple classes, the STemWin
professional graphics stack developed by ST with SEGGER, the FatFS open-source
file system, and the FreeRTOS open-source real-time operating system, coming
with optional CMSIS-RTOS programming interface. The middleware components have
user-friendly license terms, either as open-source software or software
delivered and supported by ST.

The STM32CubeMX tool and STM32CubeF4 embedded software are available
immediately, free of charge, directly from A
large number of application-level demonstrations are available, illustrating
how to use components of the HAL and middleware, targeting IAR(TM), Keil(TM)
and GCC compilers. These can be run directly on the wide variety of STM32 F4
prototyping boards available from ST, which include ST evaluation boards,
Discovery boards, and the new extendable Nucleo boards, which are
mbed(TM)^1-enabled, feature Arduino connectivity, and are currently rolling
out to support the entire STM32 family.
