STMicroelectronics’ free, Eclipse-based environment that integrates peripheral configuration (CubeMX) with code editing.
Crucial to the ecosystem is the ST-Link debug probe. Unlike older microcontrollers that required "burning" code via a bootloader, the STM32 ecosystem supports Serial Wire Debug (SWD). This allows developers to pause the processor, step through code line The Stm32f103 Arm Microcontroller And Embedded Systems
