EE319K Introduction to Embedded Systems EE319K will continue
the bottom-up educational approach, started in EE302 and EE306. The overall
educational objective is to allow students to discover how the computer interacts
with its environment. It will provide hands-on experiences of how an embedded
system could be used to solve EE problems. The focus will be understanding and
analysis rather than design. The analog to digital converter (ADC) and digital
to analog converter (DAC) are the chosen mechanism to bridge the CE and EE
worlds. EE concepts include Ohms Law, LED voltage/current, resistance
measurement, and stepper motor control. CE concepts include I/O device drivers,
debugging, stacks, FIFO queues, local variables and interrupts. You may
use, edit, run or distribute these files as long as the copyright notices
within the files remain. No specific warrantee exists concerning the accuracy
or reliability of these examples. I think they work, but history has shown,
sometimes I can be wrong.
