1. What is the STM32CubeMP13 Package

STM32CubeMP13 Package, running on the Arm^® Cortex^®-A7 processor, consists of:

• The hardware abstraction layer (HAL), enabling portability between different STM32 devices via standardized API calls
• The low-layer API (LL), a light-weight, optimized, expert oriented set of APIs designed for runtime efficiency and so enhanced performance
• The board support package drivers (BSP), based on HAL drivers, an API set for the evaluation board and third-party components.
• A collection of middleware components (such as AzureRTOS)
• A collection of examples, running on an MPU board and allowing demonstration of a basic implementation of features from a set of IPs

2. Software architecture overview

3. STM32CubeMP13 Package structure

This chapter describes the structure of the STM32CubeMP13 Package (drivers, middleware components...).

STM32CubeMP13 Package offers a highly portable Hardware Abstraction Layer (HAL), built around a generic and modular architecture.
