The Cortex Microcontroller Software Interface Standard is a software standard by ARM that defines a number of foundational interfaces for Cortex-M microcontrollers.

We use only use these parts of CMSIS:

  • The modm:cmsis:core module provides access to the ARM Cortex-M peripherals via CMSIS-CORE.
  • The modm:cmsis:device module provides access to the peripherals of the modm:target devices via the vendor's CMSIS implementation.
  • The modm:cmsis:dsp module provides a basic digital signal processing library via CMSIS-DSP.

This module is only available for rp, sam, stm32.
