What are the preferred Integrated Development Environments (IDEs) for STM32 microcontrollers?

Introduction

A typical question new STM32 users ask is what are the preferred IDEs for developing and debugging application code.  While there are a variety of IDEs available that support the STM32, the most used are ST’s STM32CubeIDE, IAR’s EWARM and Keil’s uVision (MDK). A quick overview of each of the IDEs follows:

1. STM32CubeIDE

This is STMicroelectronics’ IDE tool that and is free of charge and supports all the  STM32 products.
STM32CubeIDE is an all-in-one multi-OS (Windows, MacOS, Linux) development tool, which is part of the STM32Cube software ecosystem. STM32CubeIDE is an advanced C/C++ development platform with peripheral configuration, code generation, code compilation, and debug features for STM32 microcontrollers and microprocessors. It is based on the Eclipse®/CDT framework and GCC toolchain for the development, and GDB for the debugging.

2. IAR EWARM

This is an IDE from our partner IAR Systems available for Windows hosts only and embeds a programming tool.
STM32CubeMX can be used for the configuration phase of the project and allows generating the EWARM project files for a seamless adoption of this professional IDE.
This tool comes with free of charge evaluation versions according to the following conditions:

• Unlimited time but 16KB limited Cortex-M0/M0+ application size, fit for the STM32C0, STM32F0, STM32G0 and STM32L0 Series
• Unlimited time but 32KB limited Cortex-M application size, fit for any other STM32
• 30-day limited time per-host PC, unlimited application size

The full version requires a commercial license available in a range of product editions including Functional Safety pre-certified versions.
Several licensing models are also provided, such as Node locked, USB key locked and Network.
The IDE integrates with additional IAR Systems software tools such as:

• C-STAT for static C/C++ code analysis compliant with standards such as MISRA C/C++
• C-RUN for runtime error debugging
• C-TRUST for Security developments
• VisualState, for state machine modelling

The IDE is compatible with a wide variety of 3^rd party debug probes and IAR Systems provides its own Debug and Trace capable probes such as:

• I-Jet
• I-JetTrace

This IDE supports all the STM32 products and ST provides project examples in the STM32Cube Packages enabling immediate use of this IDE.

3. Keil uVision (MDK)

This is an IDE from our partner ARM Keil available for Windows hosts only and embeds a programming tool.
STM32CubeMX can be used for the configuration phase of the project and allows generating the MDK5 project files for a seamless adoption of any editions of this professional IDE.
The IDE is available in four main editions: MDK-Lite, MDK-Essential, MDK-Plus and MDK-Professional and a variety of licensing models combining:

• Time limits (1-year, perpetual)
• Topology (node locked, FlexLM)

Details are available at Compare MDK Editions (Keil.com).
MDK-Professional enables a Functional Safety pre-certified tool and Functional Safety pre-certified middleware modules.
This tool comes with free of charge evaluation versions according to the following conditions:

• MDK-Essential, special edition for STMicroelectronics
  • Unlimited application size for Cortex-M0/M0+, fit for the STM32C0, STM32F0, STM32G0 and STM32L0 Series
• MDK-Lite
  • Unlimited time but 32KB limited Cortex-M application size, fit for any other STM32
• MDK-Professional
  • 7-day limited time per-host PC, unlimited application size

The IDE integrates 3^rd party plug-in commercial tools such as Gimpel Software and Parasoft static code analyzers.
MDK5 is compatible with a wide variety of 3^rd party Debug probes and ARM Keil provides its own Debug and Trace capable probes such as:

• ULINKPlus
• ULINKPro

This IDE supports all the STM32 products and ST provides project examples in the STM32Cube Packages enabling immediate use of this IDE.
