LGPLv3 Cortex-M0/M3/M4 runtime library

The libopencm3 project aims to create an open-source firmware library for various ARM Cortex-M3 microcontrollers. Currently (at least partly) supported microcontrollers: - ST STM32F1 series - ST STM32F2 series - ST STM32F4 series - NXP LPC1311/13/42/43 The library is written completely from scratch based on the vendor datasheets, programming manuals, and application notes. The code is meant to be used with a GCC toolchain for ARM (arm-elf or arm-none-eabi), flashing of the code to a microcontroller can be done using the OpenOCD ARM JTAG software. This port depends on devel/gcc-arm-embedded toolchain.
