• MicroConsult Plus:
  • All participants have the following options to further use their exercises and the solutions developed by MicroConsult from this workshop:
  • You take the files with you on a free USB stick provided by MicroConsult, or
  • You e-mail the files to your account, or
  • You get access to file download on request.
  • You get all examples for C and C++ in electronic format and can easily adjust them to your development environment.
  • You moreover get a tool and software component overview for developing embedded software.
  • You get helpful notation overviews for UML (Unified Modeling Language) and SysML (Systems Modeling Language).

Lernziele

• The EC++ workshop shows you how an object-oriented approach helps you develop higher-quality software in an embedded environment in a shorter time.
• You get a compact overview of the entire development process of embedded real-time systems - software analysis, software design, software implementation and unit test - as a basis for you to implement projects with EC++.
• You know how to design of software systems by using UML and implementation in the programming language C++.
• You thus have the required knowledge base for meeting specific software quality requirements for embedded systems, e.g. regarding runtime and code efficiency.
• Programming guidelines, such as the MISRA-C++ standard, moreover help you avoid programming errors at an early stage.
• You can use state of the art object-oriented techniques to develop high-quality, complex software systems and, at the same time, save time and money.

Zielgruppe

• The EC++ training addresses programmers, software developers, software designers and software architects who use C++ for embedded software applications based on object-oriented concepts.

Voraussetzungen

• A very good knowledge of C-programming is required; basic microcontroller knowledge of advantage.
