STMicroelectronics introduced a low-cost development environment for the STM32 microcontroller families built using the ARM Cortex-M3 processor core, which is optimized for embedded applications. The environment combines the Atollic TrueSTUDIO/STM32 development tool and ST’s ST-LINK debug probe to connect to the target via USB. The ST-LINK debug probe is available for $21. Atollic TrueSTUDIO/STM32 can be downloaded at a price of euro 995 for TrueSTUDIO/STM32 Pro. TrueSTUDIO/STM32 Lite is available for free.
Atollic TrueSTUDIO/STM32 uses the Eclipse Integrated Development Environment (IDE) framework, and features a GNU compiler/debugger for ARM processors. Pre-compiled runtime libraries are also included in the free-of-charge Lite version of the tool. Developers can access more extensive capabilities by purchasing Atollic TrueSTUDIO/STM32 Pro, a low-cost environment with extensive capabilities including C++ language support, PC-based build/debug tools allowing development before embedded hardware is available, graphical tools including UML diagram editors, and collaboration features such as version control and bug/task management.
