Introduction
STMCube
reducing development efforts, time and cost. STM32Cube covers STM32 portfolio.
STM32Cube Version 1.x includes:
• The STM32CubeMX, a graphical software configuration tool that allows to generate C
initialization code using graphical wizards.
• A comprehensive embedded software platform, delivered per series (such as
STM32CubeF3 for STM32F3 series)
– The STM32CubeF3 HAL, an STM32 abstraction layer embedded software, ensuring
maximized portability across STM32 portfolio
– A consistent set of middleware components such as RTOS, USB, STMTouch and
FatFs
– All embedded software utilities coming with a full set of examples.
The STM32CubeF3 Nucleo Demonstration platform is built around the STM32Cube HAL,
BSP and FatFs middleware component and uses almost the whole STM32 capability to load
and display full color bitmaps from a microSD card.
