  • 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:
    • Audio and voice processing
    • Connectivity
    • Cloud / IoT
    • eIQ® Machine Learning
    • Functional Safety
    • Graphics and HMI
    • Motor control
    • Security
    • Storage
    • And more
  • Software examples demonstrating the usage of peripheral drivers, RTOS wrapper drivers, middleware and RTOSes
  • Support for Partner middleware and software via Open-CMSIS-Packs
