Embedded Programming with AVR Microcontrollers

Microprocessor is the brain behind every computer and every embedded device. It is important and essential for every electronics student to understand how a microprocessor works. All microprocessors from powerful multicore processors to tiny microcontrollers works more or less in the same manner. So understanding any small microprocessor very well, gives tremendous boost in understanding how a computer works.

Atmel AVR controller is the wonderful processor with its RISC like features. It is very simple and easy processor to understand and use. To make your understanding perfect we will start designing our own processor, that makes understanding even more simple. We offer AVR kits, which you can program from the same Linux live CD.

This course should be taken after completing the C Programming on Linux. So second year second semester is the right time to do this course.
