Development toolchain IAR EWARM (IAR Embedded Workbench ) Keil MDK-ARM GCC-based IDE (ARM Atollic TrueSTUDIO ,...) Demonstration software The demonstration software is preloaded in the board Flash memory. It uses the built-in I DD measurement and touch sensing feature of the STM32L-DISCOVERY or the 32L152CDISCOVERY to automatically measure and display on the LCD the microcontroller consumption in run and low-power modes.
