Microprocessor
Course – AVR - ATmega1284P
Course Instructor:
Prof. Costas Foudas, F3.303, x8750
Laboratory
Instructor:
Course hours: To be
agreed in Autumn 2021
This is part of a new course at the Physics
Department of the University of Ioannina on programmable devices and it has
been designed as crash course on micro-controllers. Experience with digital
electronics is helpful but not necessary. The course language is English due to
the fact that all documentation about Microcontrollers is in English and freely
available in the internet.
The course goals are:
·
To teach the architecture of an AVR micro-controller.
·
To demonstrate that a micro-controller can be programmed and be useful
in everyday life applications.
·
To give the students useful professional skills.
·
To teach the basics of electronics-design by constructing various
interfaces of the micro-controller with other devices.
The basic processor is the ATMEL ATmega1284P
micro-controller.
