This Bachelor lecture teaches the basics of programming in the C programming language. Despite its long history, C is still one of the most widespread and important programming languages today, especially for system-oriented programming. It is easy to learn but difficult to master, as it contains only a few keywords and concepts, but these can be used to emulate many modern programming techniques.

In detail, it covers: General concepts of programming languages, variables and types in C, operators and expressions, control structures and functions, the preprocessor, pointers, static and dynamic memory management, error handling, bit manipulation, modules and abstract data types, unit testing and test-driven development in C.

Please note that this is not a lecture on the basics of programming. The lecture builds on the courses "Grundlegende Programmiertechniken" and "Fortgeschrittene Programmiertechniken", i.e. basic programming knowledge (e.g. variables and types, loops, subroutines and recursion) and basic knowledge of data structures and algorithms are assumed.

This masters lecture will introduce the research area of the "Internet of Things" (IoT), where billions of embedded systems (actuator, sensors) make continously data in real time to about the real world available to the Internet. Topics, that will be covered are:

Hardware plattforms (e.g. SBCs, Sensor nodes), communication protocols (e.g. IEEE 802.15.4, 6LoWPAN, CoAP, MQTT), data modelling (e.g. linked data, RDF, SSN), data management and access (e.g. SPARQL, continous queries with CQELS, "Big Data"), system software and software plattforms (e.g. Eclipse Ponte, Xively, BASE, PCOM), future work ("programmable world"). An exercise will complement the theoretical knowledge with practical task of programming IoT-Systems, e.g. with Arduinos or Raspberry Pis.
