Platform ``stm32``
==================

`The STM32 family of 32-bit Flash microcontrollers <http://www.st.com/web/en/catalog/mmc/FM141/SC1169?sc=stm32>`_ based on the ARM® Cortex®-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

The unparalleled and large range of STM32 devices, based on an industry-standard core and accompanied by a vast choice of tools and software, makes this family of products the ideal choice, both for small projects and for entire platform decisions.
