is a development environment for Arm Cortex-M series microcontrollers which contains everything for creating and testing applications in assembly, C or C++. MDK is split into and making new device support and middleware updates independent from the tools.
The MDK-Middleware software pack contains components for IPv4 and IPv6 networking, USB Host and Device communication, file system for data storage, and a graphical user interface. The real-time operating system Keil RTX5 is used by all middleware components for task scheduling.
This documentation describes:
Software components outside the scope of this documentation are:
