Lecture 3: Introduction to AVR I/O Ports and I/O Instructions 

This video in the series created by Teaching Assistant Ph.D. student specifically for CEEN-1060 (Microcontroller Applications), shows these students about the AVR's I/O ports. Topics include the concept behind the physical ports, the programmer's model and three registers (DDRx, PORTx, and PINx), configuring and maniupulating them via IN/OUT instructions as well as manipulating at the bit-level using the CBI/SBI instructions. Conditional I/O bit-test instructions such as SBIS and SBIC are also discussed. Concepts are then illustrated using Atmel Studio 7 simulator.
While the video might be useful in some respects to the general public, please note the video provides information that is specific to this course.
