The MDK-ARM-CM-FL-LC is a standard edition software development environment for ARM Cortex-M processor based devices with perpetual floating license type available in downloadable form. This microcontroller development kit is specifically designed for microcontroller applications and it is easy to learn and use, yet powerful enough for the most demanding embedded applications. It combines the ARM C/C++ compiler with the Keil RTX real time operating system and middleware libraries. All tools are integrated into µVision which includes project management, editor and debugger in a single easy to use environment. The fully integrated ARM C/C++ compiler offers significant code size and performance benefits to the embedded developer, however, MDK can also be used with the GNU GCC compiler.
