Getting started with STM32CubeF2 firmware package
Introduction
The STMCube
reducing development efforts, time and cost. STM32Cube covers the STM32 portfolio.
STM32CubeVersion 1.x includes:
• The STM32CubeMX, a graphical software configuration tool that allows the generation of
C initialization code using graphical wizards.
• A comprehensive embedded software platform, delivered per series (such as
STM32CubeF2 for STM32F2 Series)
– The STM32Cube HAL, an STM32 abstraction-layer embedded software, ensuring
maximized portability across STM32 portfolio
– The Low Layer APIs (LL) offering a fast lightweight expert-oriented layer which is
closer to the hardware than the HAL. The LL APIs are available only for a set of
peripherals
– A consistent set of middleware components such as RTOS, USB, TCP/IP and
graphics
– All embedded software utilities, with a full set of examples.
