In their own words
e² studio
e² studio is an Eclipse-based integrated development environment for Renesas microcontrollers, supporting work from sample-code access through debugging. Its project wizard creates MCU projects with basic sample code, while Smart Configurator sets clocks, pins, and interrupts and generates code for those settings. The Eclipse CDT editor provides completion, syntax coloring, navigation, folding, automated code constructs, preprocessor checking, and refactoring. Developers can choose Renesas or partner-vendor compilers, but must install them separately; compiler packages are not included in the IDE download. Debugging uses Eclipse CDT's GDB and includes register and memory views, breakpoints, real-time memory display, tracing, and peripheral-register display. Listed hardware includes Renesas E2, E2 Lite, and E20 emulators and SEGGER J-Link. Supported MCU families include RA, RZ, RL78, RX, RH850, and RISC-V. The Linux host version does not support the RE family or Renesas Synergy. e² studio runs on Windows, Linux, and macOS and costs nothing, with no paid version. Separate compiler packages may have their own license terms or evaluation limits.
STM32CubeIDE
STM32CubeIDE is a C/C++ environment for editing, compiling, and debugging code for STM32 devices. ST offers an Eclipse-based IDE and a Visual Studio Code variant, and identifies the VS Code version as its primary IDE focus. The Eclipse version supports all STM32 microcontrollers and microprocessors; the VS Code version supports all STM32 microcontrollers. Both are listed for 64-bit Windows, Linux, and macOS.
The IDE includes a C/C++ editor and supports GCC and Clang toolchains. Debugging features include breakpoints, CPU core registers, memory and live-data views, SFR registers, RTOS debugging, and fault analysis. Supported probes include ST-LINK and SEGGER J-Link. ST says the IDE is commonly used with STM32CubeMX and is compatible with TouchGFX Designer, STM32Cube AI Studio, and motor control workbench. The VS Code variant uses CMake and Ninja. Telemetry is optional and can be disabled in Visual Studio Code settings. It is free to download and use, though the ST application is proprietary.
