This book covers all aspects of embedded systems design using HCS08 microcontrollers and it was conceived to be not only a learning book, but also a complete reference guide to help design engineers in their projects. Every chapter was conceived to provide a solid knowledge with an increasing learning curve, from basic input/output experiments to more complex experiments using timers, serial communication and other peripherals. The last chapter presents some applications using the HCS08 microcontrollers such as: thermometer, analog bar graph, slave I2C device, RC servo controller, RC relay,...
