  * Also read the application note 1456 which provides a general information about Lab 3 stationary project:
    * {{:an-1456_c_os-ii_dragon12_development_board_.pdf}}

==== Evaluation ====
Demonstrate the uploaded program to your T.A. Provide brief answers to the following questions:
  * What is the process of creating a new task in μC/OS-II? Provide a pseudo sample code by study “KeypadTask” code block used in the lab.
  * Explain how OSFlagPend function and how it prevents the “KeypadTask” from accessing the critical LCD resource?

==== Procedure ====
  * Open the lab stationary using CodeWarrior located in:
<code>LAB03/Micrium/Software/EvalBoards/Freescale/MC9S12DG256B/WytecDragon12/Metrowerks/Paged/
   OS-Probe-LCD/OS-Probe-LCD.mcp</code>
  * Recompile the project and transfer the binaries to Dragon12 board as explained in [[lab1|Lab 1]]. {{:icon3.jpg}}
