Now that we can write characters to the GLCD screen, some interesting possibilities present themselves. The first one to consider is a simple character-based game application known as PONG. Pong was one of the first arcade video games featuring 2D graphics, originally marketed by ATARI Inc. (http://en.wikipedia.org/wiki/Pong). We'll develop the game in stages, as this is a good development strategy. We'll start by describing a simple recipe named Bounce with limited functionality. The idea of this recipe is just to animate a ball so that it appears to bounce around the screen. Provided we can redraw the ball more than 25 times a second (25 Hz), it will appear to move. The ball is represented by a character bitmap.

Overview of this book
Embedded microcontrollers are at the core of many everyday electronic devices. Electronic automotive systems rely on these devices for engine management, anti-lock brakes, in car entertainment, automatic transmission, active suspension, satellite navigation, etc. The so-called internet of things drives the market for such technology, so much so that embedded cores now represent 90% of all processor’s sold. The ARM Cortex-M4 is one of the most powerful microcontrollers on the market and includes a floating point unit (FPU) which enables it to address applications.
The ARM Cortex-M4 Microcontroller Cookbook provides a practical introduction to programming an embedded microcontroller architecture. This book attempts to address this through a series of recipes that develop embedded applications targeting the ARM-Cortex M4 device family. The recipes in this book have all been tested using the Keil MCBSTM32F400 board. This board includes a small graphic LCD touchscreen (320x240 pixels) that can be used to create a variety of 2D gaming applications. These motivate a younger audience and are used throughout the book to illustrate particular hardware peripherals and software concepts.
C language is used predominantly throughout but one chapter is devoted to recipes involving assembly language. Programs are mostly written using ARM’s free microcontroller development kit (MDK) but for those looking for open source development environments the book also shows how to configure the ARM-GNU toolchain. Some of the recipes described in the book are the basis for laboratories and assignments undertaken by undergraduates.
