STMicroelectronics’ STM32 microcontroller (MCU) embedded-software design tools offers free and ready-to-use dedicated middleware stacks, such as touch-sense and USB libraries, along with drivers for STM32 peripherals through the hardware abstraction layer (HAL), to simplify porting of applications from one STM32 series to another. The STM32CubeF3 and STM32F0 embedded software bring the efficiency of the STM32Cube software platform plus STM32Nucleo development boards to projects targeting STM32 F3 mixed-signal and STM32 F0 entry-level devices. STM32Nucleo boards assist early application development, leveraging Arduino application shields as well as dedicated ST extension boards. The mbed-enabled boards can access all device I/Os and integrate an ST-Link debugger/programmer. When using the embedded software with the latest version of the STM32CubeMX PC-based tool, the MCU can be configured with graphical wizards—it requires just a click to generate initialization C-code that can be used in many third-party development tools.
