UM2217 User Manual Description of STM32H7 HAL drivers Introduction STMCubeTM is an STMicroelectronics original initiative to make developers' lives easier by reducing development effort, time and cost. STM32Cube covers the whole STM32 portfolio. STM32Cube includes: • 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 STM32CubeH7 for STM32H7 Series) – The STM32Cube HAL, STM32 abstraction layer embedded software ensuring maximized portability across the STM32 portfolio – A consistent set of middleware components such as RTOS, USB, TCP/IP, Graphics – All embedded software utilities delivered with a full set of examples. The HAL driver layer provides a simple generic multi-instance set of APIs (application programming interfaces) to interact with the upper layer (application, libraries and stacks). It is composed of generic and extension APIs. It is directly built around a generic architecture and allows the built-upon layers, such as the middleware layer, to implement their functions without in-depth knowledge how to use the MCU. This structure improves the library code reusability and guarantees easy portability to other devices. The HAL drivers include a complete set of ready-to-use APIs which simplify the user application implementation. As an example, the communication peripherals contain APIs to initialize and configure the peripheral, to manage data transfers based on polling, to handle interrupts or DMA, and to ma
