  • PIC Microcontrollers are present in almost every new electronic application that is released from garage door openers to the iPhone. With the proliferation of this product more and more engineers and engineers-to-be (students) need to understand how to design, develop, and build with them. Martin Bates, best-selling author, has provided a step-by-step guide to programming these microcontrollers (MCUs) with the C programming language.

  • In a time when digital electronics is becoming more complex and less accessible to students and low-end project and product developers, microcontrollers have become the tools of choice for learning about electronics and programming as well as providing the capabilities needed to create sophisticated applications cheaply and easily. If you were to look through any electronics magazine, you would discover that almost every example application uses a microcontroller (often abbreviated to just MCU) to provide a user interface, sequence operations, and respond to changing inputs.

  • The revisions required in the second edition of this book are mainly due to the rapid development of microcontroller technology. As the PIC family of devices has grown, more features have been incorporated at lower cost. So, while the focus of the first edition was the popular 16F84 chip, and this remains a valuable reference point for the beginner, the scope has been expanded so that a broader understanding of the range microcontroller types and applications can be gained.

  • Circumstances that we find ourselves in today in the field of microcontrollers had their beginnings in the development of technology of integrated circuits. This development has made it possible to store hundreds of thousands of transistors into one chip. That was a prerequisite for production of microprocessors , and the first computers were made by adding external peripherals such as memory, input-output lines, timers and other. Further increasing of the volume of the package resulted in creation of integrated circuits. These integrated circuits contained both processor and peripherals.

  • Functionally, the CHMOS devices (designated with “C” in the middle of the device name) me all fiuy compatible with the 8051, but being CMOS, draw less current than an HMOS counterpart. To further exploit the power savings available in CMOS circuitry, two re- duced power modes are added l Software-invoked Idle Mode, during which the CPU is turned off while the RAM and other on-chip peripherals continue operating. In this mode, cur- rent draw is reduced to about 15% of the current drawn when the device is fully active.
