Preface

Martin Bates

The PIC is one of the biggest selling small microcontrollers. When it first became available, it was not only technically innovative, but helped to make the teaching of microelectronics much more interesting. A small controller with flash memory meant that a great variety of student projects could be realised quickly and easily. It helped that the development toolkit was free as well.

It has always been a problem in electronics that you cannot see a circuit working in the same way that a mechanical engineer can see a steam engine pumping up and down. Sure, we can see the screen flickering on a television, or an electric motor spinning, but you cannot see electrons or volts directly. As a result, it has always been that ...
