  • Gray Code Encoders (.pdf)
    Absolute encoders provide parallel absolute position information in a binary. format. Some absolute encoders use a special binary code known as gray code. The main characteristic of gray code is that only one bit differs from any adjacent. numbers. To understand the difference between gray code
  • Modifying PIC16C54A Code for the PIC16C58A
    Code written for a PIC16C54A device can be easily modified and used in a PIC16C58A. Therefore, a PIC16C58A may be used in place of a PIC16C54A. The PIC16C58A and the PIC16C54A are pin-compatible devices. Also, the PIC16C58A has more than enough memory (program and data) to support PIC16C54A code.
  • Save Time With Reusable Code
    Standardized programming for automation equipment is here to stay. At the forefront is IEC 61131-3-compatible software, which generates standardized code for use on any number of controls.
  • 2008 Code Digest
    Cooper Crouse-Hinds has revised its Code Digest for 2008 to meet the needs of design personnel for a ready reference to equipment and installation ideas in hazardous locations. Selected Articles from the National Electrical Code (R) have been explained with diagrams and photographs of electrical
  • The Ease Of Bar Code Technology
    In an ever-changing business world, the collecting, processing and interpreting of data, in a fast effective way, is essential. This document gives a brief summary of bar code technology, how and where to use and touches on the merits of the technology.
  • PIC16CR ROM Code Submission
    Microchip Technology is now offering a number of established Flash devices in a ROM version for high volume customers. This application note details some of the differences between the Flash and the ROM devices, and also outlines any requirements placed on the customer code. The ROM family
  • An Introduction to KEELOQ Code Hopping
    available but, because of their high cost and certain practical disadvantages, they are not widely used in commercial remote control devices. The popular unidirectional transmission systems currently have two very important security shortcomings: the codes they transmit are usually fixed and the number
  • Code development for the PIC16C52
    To develop code on a PIC16C52 device, a PIC16C54/JW part can be used. In order to use a PIC16C54/JW device, the following conditions should be followed: 1. A PIC16C54/JW has 512 words (0x1FF) of program memory, whereas a PIC16C52 has 384 bytes (0x17F) of program memory. The ?extra? locations should
  • What's Bar Code Verification?
    Bar codes are the most cost-effective way of entering data. Bar code verification ensures maximum reliability, thus improving quality, increasing productivity, eliminating unnecessary costs of goods and acquiring accurate quality-control information. * Increase efficiency and spur cost reduction
  • Cyclic Redundancy Code (CRC)
    obtained when M is divided by G. INTRODUCTION CRC is one of the most versatile error checking EQUATION 1: algorithm used in various digital communication M = G * Q + R systems. CRC stands for Cyclic Redundancy Code Check or simply Cyclic Redundancy Check. M + R = GQ = M - R Since addition
