ELT 253 Microprocessor Systems

Lecture Hours: 3
Lab Hours: 3
Credits: 4

Explores hardware and software concepts used with microcomputers. Stresses theory and laboratory application of interfacing criteria, hardware and software troubleshooting techniques, writing machine language programs, and using written programs for testing hardware and system interface. Promotes and supports sustainable and green technologies.

Prerequisite: ELT 244 and ELT 252, each with a grade of C or better; or consent of instructor.
Student Learning Outcomes:
