Lernziele

• This training focuses on the hardware-near C-programming of 8, 16 or 32 bit microcontroller architectures.
• You learn how to program a HW abstraction layer according to an architecture model. OS mechanisms and services are explained by programming a scheduler.
• You get an overview of the entire lifecycle of a product - from the idea to project planning, SW development process, test planning, quality planning, acceptance, commissioning, operation and decommissioning.
• You are able to efficiently develop programs for an embedded system in C according to the guidelines of modernsoftware engineering.
• You are familiar with using pointers, function pointers and structures.
• Based on your knowledge of programming/coding guidelines and software quality features, functional and non-functional requirements as well as internal quality and generate software that is reusable, extendable and easily tested.
• In addition, you know all stages of a software development process, from the idea to system acceptance.

Zielgruppe

• Software developers, software architects

Voraussetzungen

• A good understanding of ANSI-C and microcontroller architectures.
