Simplicity SDK vs STM32CubeIDE

Simplicity SDK has no write-up on Specifiction yet; its figures are above.

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.
