Synopsis

This book assumes no previous knowledge of either microcontrollers or C. We will use a particular microcontroller, the Freescale MC9S12DG256, on a popular, low-cost development board, the miniDRAGON-Plus2TM from Wytec, Inc. The miniDRAGON-Plus2 is low cost, has a small footprint that makes it suitable for embedded projects, offers convenient female headers for connecting to your circuits on the built-in protoboard, and has built-in connectors for an LCD display and keypad. There is also an on-board speaker, a built-in H-bridge for driving motors, convenient headers for connecting servos and an accelerometer board available from Wytec. You will quickly be able to do lots of fun stuff with this board. This extensive list of features makes the programming of these microcontrollers, particularly using assembly language, a daunting task. Other books and datasheets spend a great deal of time explaining how to program the many I/O registers to perform the wide variety of different I/O tasks. However, it is usually something fairly simple that you are trying to do; e.g. turn on a light, read a switch, turn on a motor at some speed, read the value of an A/D converter, or measure some time interval. If you just want to learn how to do these simple things without getting bogged down in the minutia of the microcontrollers I/O and internal operation, then this book is for you. In this book you will learn to write programs in C and compile them using CodeWarriorTM, an industry-strength integrated development environment for microcontrollers. CodeWarrior itself can be daunting, but we will make it easy for you to learn what you need to quickly get your microcontroller to work. We do this by providing you with an LBE_miniDRAGON_Plus2 Stationery project from which you can easily build your own particular application. This project will contain an assembly language file that we have written to do all the low-level interaction with the I/O registers
