Ready for mbed OS5-A platform OS for IoT devices

  • ARMR mbed™ is a free, open-source embedded operating system designed specifically for the “things” in the Internet of Things.
    • Enables application and component libraries to work unchanged across MCUs, hence provides portability for developers and helps to deliver network effects for contributors
  • Consistent boot and C/C++ runtime across MCUs, including support across different toolchains, std library integrations
  • RTOS kernel
    • Built on the established, widely used, open source CMSIS-RTOS RTX
    • Very small kernel optimised for constrained memory devices
  • Common Driver APIs for all common peripherals, supported across all MCUs
  • Enhanced connectivity and security stack
