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.
