Code

The µVision® IDE combines project and run-time environment management, as well as build facilities with source code editing and program debugging in a single environment.

Finetuned over many years, this intuitive Windows®-based IDE brings a series of smart features to developers’ fingertips. This includes the µVision Pack Installer, which is an intelligent component manager that takes care of downloading, installing and keeping track of inter-dependencies for each component used in the code.

Build

Built to generate optimum code size and best-in-class performance, Keil MDK includes the leading Arm Compiler. This C/C++ compiler includes assembler, linker and highly optimized run-time libraries to ensure optimal performance.

Arm Compiler 6 is qualified for functional safety applications by TÜV SÜD.

Debug

Test, verify and optimize application code using the µVision debugger in a single environment.

In addition to responsive run-control debug, MDK enables the use of data trace and even non-intrusive instruction trace to facilitate debug and system optimization, supporting many third-party debug adapters. When paired with a debug probe from the ULINK family, superior features like streaming trace and power measurement are available.

Optimize

At a glance, developers can see how code is performing and where inefficiencies are.

  • Component Viewer, Event Recorder, and Event Statistics show execution status, event, timing, and power information about the application execution.
  • Data and Event Trace outputs details about interrupts and exceptions. It also communicates program events and enables printf-style debug messages.
  • Instruction Trace streams the complete program execution for recording and analysis.
