=== Conditions for getting a certificate (Übungsschein) ===

Participation in the exercises on a regular basis followed by an exam at the end of the semester. During the first half of the exercises, students will work with the ATMEL [[http://www.atmel.com/dyn/products/product_card.asp?part_id=2010|ATmega16]] AVR microcontroller (8bit RISC). In the second half, students will learn about PLCs (Programmable Logic Controllers).

== Microcontroller Part ==

  * The software we are using is Freeware. Since the Atmel Studio also offers a simulator (running in simulator mode as soon as no device is connected) you can experiment with it at home.
  * You need [[http://sourceforge.net/projects/winavr|WINAVR]] and the [[http://www.atmel.com/dyn/products/tools_card.asp?tool_id=2725|AVR studio 4]]. A local copy of the WIN AVR Studio used in the lab course can be found [[http://www-i11.informatik.rwth-aachen.de/fileadmin/user_upload/Redakteure/Vorlesungen/05winter/EinfEingSyst/WinAVR-20040720-install.exe|here]].
  * Slides with a detailed step by step description of the design flow using WINAVR along with the AVR Studio can be found [[http://www-i11.informatik.rwth-aachen.de/fileadmin/user_upload/Redakteure/Vorlesungen/05winter/EinfEingSyst/Design%20steps%20%28Slides%29.pdf|here]] (501kB).
  * A short overview can be found [[http://www-i11.informatik.rwth-aachen.de/fileadmin/user_upload/Redakteure/Vorlesungen/05winter/EinfEingSyst/Design_with_WINAVR.pdf|here]] (10kB).
  * More information can be found on [[http://www.atmel.com/|atmel.com]] and in the according sections of Falk Salewski's Link List.
