Release Notes for STM32F7xx HAL Drivers

Copyright 2017 STMicroelectronics

 The hardware abstraction layer (HAL) provides low level drivers and the hardware interfacing methods to interact with upper layer (application, libraries and stacks).  It includes a complete set of ready-to-use APIs, that are feature-oriented instead of IP-Oriented to simplify user application development.
