ELT 622 - Microcontrollers

Credits: 3
Lecture Hours: 3
Lab Hours: 0
Practicum Hours: 0
Work Experience: 0
Course Type: Voc/Tech
This course covers two major areas of microcomputers and microcontrollers. The first is an investigation of the specific architecture of microcontrollers and fundamental microcomputer hardware. The second area is software and studies-specific c language and assembly language instructions for common routines and program structures.
Corequisite: ELT 623
