MCUXpresso Software Development Kit (SDK)

Overview

The MCUXpresso SDK is a comprehensive software enablement package designed to simplify and accelerate application development with Arm^® Cortex^®-M-based devices from NXP, including its general purpose, crossover and wireless-enabled MCUs. The MCUXpresso SDK includes production-grade software with integrated RTOS (optional), integrated enabling software technologies (stacks and middleware), reference software, and more.

In addition to working seamlessly with the MCUXpresso IDE, the MCUXpresso SDK also supports and provides example projects for IAR, KEIL, and GCC with Cmake.

Underscoring our commitment to high quality, the MCUXpresso SDK is MISRA compliant and checked with Coverity^® static analysis tools. SDK packages are available in custom downloads based on user selections of MCU, evaluation board, and optional software components.

Features

The MCUXpresso SDK consists of the following runtime software components:

Arm^® CMSIS-CORE startup and device header files and CMSIS-DSP standard libraries
Open-source peripheral drivers that provide stateless, high-performance, easy-to-use APIs
Drivers for communication peripherals also include high-level transactional APIs for high-performance data transfers and RTOS wrappers that leverage native RTOS services to better comply with the RTOS cases
High-quality software: all drivers and startup code are MISRA-C: 2004 compliant and checked with Coverity^® static analysis tools
Real-time operation systems (RTOS) kernels pre-integrated: Azure^® RTOS ThreadX and FreeRTOS^™
Enabling software technologies (stacks and middleware) from NXP and partners including:
- Graphics and HMI
- Audio and voice processing
- Cloud connectivity
- Motor control
- Security
- Storage
- eIQ^® Machine Learning
- Wireless and wired connectivity
- Functional safety
- And more
Software examples demonstrating the usage of peripheral drivers, RTOS wrapper drivers, middleware and RTOSes
Free to use Azure RTOS middleware on select platforms, including USBX, GUIX, FileX, LevelX and NetX Duo
Also available as CMSIS Device Family Pack
