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.

Metrowerks Project

HW8 can be done in either codepad, or Metrowerks. If you use Metrowerks, then this project can be used.

HW10Moore.zip **to do**, old not for 2012

htm file with HW10 description and Metrowerks Project. See your professor for when/how HW10 is due.

There are three options for HW10. 1) Run in Codepad with printf (use the main.c file in sources directory). 2) Compile in Metrowerks and debug in TExaS (use the Metrowerks project and the TExaS files in the bin folder). 3) Compile in Metrowerks and debug on real board (use the Metrowerks project)
