Programming-8Bit-PIC
Foreword Embedded microcontrollers are everywhere today. In the average household you will find them far beyond the obvious places like cell phones, calculators, and MP3 players. Hardly any new appliance arrives in the home without at least one controller and, most likely, there will be several—one microcontroller for the user interface (buttons and display), another to control the motor, and perhaps even an overall system manager. This applies whether the appliance in question is a washing machine, garage door opener, curling iron, or toothbrush. If the product uses a rechargeable battery, modern high density battery chemistries require intelligent chargers. A decade ago, there were significant barriers to learning how to use microcontrollers. The cheapest programmer was about a hundred dollars and application development required both erasable windowed parts—which cost about ten times the price of the one time programmable (OTP) version—and a UV Eraser to erase the windowed part. Debugging tools were the realm of professionals alone. Now most microcontrollers use Flash-based program memory that is electrically erasable. This means the device can be reprogrammed in the circuit—no UV eraser required and no special packages needed for development. The total cost to get started today is about twenty-five dollars which buys a PICkit™ 2 Starter Kit, providing programming and debugging for many Microchip Technology Inc. MCUs. Microchip Technology has always offered a free Integrated Development Environment (IDE) including an assembler and a simulator. It has never been less expensive to get started with embedded microcontrollers than it is today. While MPLAB® includes the assembler for free, assembly code is more cumbersome to write, in the first place, and also more difficult to maintain. -

The Myth of the Innovator Hero - Business - the Atlantic
The Myth of the Innovator Hero - Business - The Atlantic http://www.theatlantic.com/business/print/2011/11/the-myth-of-the-inno... Print | Close By Vaclav Smil Every successful modern e-gadget is a combination of components made by many makers. The story of how the transistor became the building block of modern machines explains why. WIKIPEDIA: Steve Jobs, Thomas Edison, Benjamin Franklin We like to think that invention comes as a flash of insight, the equivalent of that sudden Archimedean displacement of bath water that occasioned one of the most famous Greek interjections, εὕρηκα. Then the inventor gets to rapidly translating a stunning discovery into a new product. Its mass appeal soon transforms the world, proving once again the power of a single, simple idea. But this story is a myth. The popular heroic narrative has almost nothing to do with the way modern invention (conceptual creation of a new product or process, sometimes accompanied by a prototypical design) and innovation (large-scale diffusion of commercially viable inventions) work. A closer examination reveals that many award-winning inventions are re-inventions. Most scientific or engineering discoveries would never become successful products without contributions from other scientists or engineers. Every major invention is the child of far-flung parents who may never meet. These contributions may be just as important as the original insight, but they will 1 of 4 11/20/2011 8:48 PM The Myth of the Innovator Hero - Business - The Atlantic http://www.theatlantic.com/business/print/2011/11/the-myth-of-the-inno... not attract public adulation. -
IEEE Spectrum: 25 Microchip
IEEE Spectrum: 25 Microchips That Shook the World http://www.spectrum.ieee.org/print/8747 Sponsored By Select Font Size: A A A 25 Microchips That Shook the World By Brian R. Santo This is part of IEEE Spectrum 's Special Report: 25 Microchips That Shook the World . In microchip design, as in life, small things sometimes add up to big things. Dream up a clever microcircuit, get it sculpted in a sliver of silicon, and your little creation may unleash a technological revolution. It happened with the Intel 8088 microprocessor. And the Mostek MK4096 4-kilobit DRAM. And the Texas Instruments TMS32010 digital signal processor. Among the many great chips that have emerged from fabs during the half-century reign of the integrated circuit, a small group stands out. Their designs proved so cutting-edge, so out of the box, so ahead of their time, that we are left groping for more technology clichés to describe them. Suffice it to say that they gave us the technology that made our brief, otherwise tedious existence in this universe worth living. We’ve compiled here a list of 25 ICs that we think deserve the best spot on the mantelpiece of the house that Jack Kilby and Robert Noyce built. Some have become enduring objects of worship among the chiperati: the Signetics 555 timer, for example. Others, such as the Fairchild 741 operational amplifier, became textbook design examples. Some, like Microchip Technology’s PIC microcontrollers, have sold billions, and are still doing so. A precious few, like Toshiba’s flash memory, created whole new markets. -
An Introduction to Microcontrollers and Embedded Systems
AN INTRODUCTION TO MICROCONTROLLERS AND EMBEDDED SYSTEMS Tyler Ross Lambert MECH 4240/4250 Supplementary Information Last Revision: 6/7/2017 5:30 PM Summary Embedded systems in robotics are the framework that allows electro-mechanical systems to be implemented into modern machines. The key aspects of this framework are C programming in embedded controllers, circuits for interfacing microcontrollers with sensors and actuators, and proper filtering and control of those hardware components. This document will cover the basics of C/C++ programming, including the basics of the C language in hardware interfacing, communication, and algorithms for state machines and controllers. In order to interface these controllers with the world around us, this document will also cover electrical circuits required to operate controllers, sensors, and actuators accurately and effectively. Finally, some of the more commonly used hardware that is interfaced with microcontrollers is gone over. Table of Contents 1.
