CMSIS Version 5

5.9.0

CMSIS is a set of tools, APIs, frameworks, and workflows designed to simplify software re-use, reduce the learning curve for microcontroller developers, and accelerate project build and debug processes. It was initiated as a vendor-independent hardware abstraction layer for Arm® Cortex®-M based processors and later expanded to support entry-level Arm Cortex-A based processors. CMSIS aims to provide a consistent approach to interface with peripherals, real-time operating systems, and middleware components.

Features

Simplifies software re-use and reduces the learning curve.
Speeds up project build, debug, and time to market for new applications.
Provides generic tool interfaces and consistent device support.
Enables the combination of software components from multiple vendors.
