Software and System Design
 
  1.  Glossary and Terms - This gives brief descriptions of terms frequently encountered.
  2.  Stack Model for the HCS12 - Discusses the basics of the stack for the HC12 and HCS12.
  3.  String and Array Addressing - A simple conceptual example that shows how to use a pointer to move along a string or an array.
  4.  Using D-Bug12 - Simple tutorial which introduces the DBug12 monitor and the basics of how to
  5. use it.
  6.   D-Bug12 Program Demo - Procedure to load and run a simple program using the D-Bug12  "load" command.
  7.  Switch Debouncing - Description of switch debouncing phenomenon, along with software solutions to switch debouncing.
  8.  Input, Output and Subroutines - A short tutorial illustrating the basics of inpout/output on the Dragon12, as well as the basics of how to use subroutines. The program will flash all the LEDs when first run, and will then flash particular LEDs for a fixed length of time in response to pushing a given switch. A subroutine is used to generate the timing requirements for the program.
  9.  Interrupts - Brief overview of the key concepts involved with interrupts on the HCS12.
  10.  Linux and DBug12 - The basics of how to use a Dragon12 board and DBug12 under linux.
