Golf Scorecard Logger Introduction: PC To automate and ease the scorekeeping of golf players matches for calculation of individual handicap scores and statistical illustration, a hand-held electronic scorecard iButton e r logger unit is developed, with the Re ad n implementation of the 1-Wire bus and tto i Bu iButtons. The logged data is downloaded to a PC, where the handicap is calculated and statistical data saved to illustrate the players progress over a period of time. -This will open up new opportunities for golf players of storing and analyse Scorecard Logger the scores, where improvement can be tracked. Scorecard Student: Carsten Kristiansen Supervisor: Alan Edgar iButton Implementation The iButton with a size of a one pound coin is the players link between the Scorecard Logger and the PC. With the Dallas 1-Wire communication bus, an iButton is used to identify the player and store the scores of a match, and enable the user to bring this data anywhere. Features of the DS1996 iButton: iButton reader at the Scorecard Logger: 64kbit nonvolatile memory. 142kbit/sec communication. 64 bit unique ROM registration number 256 bit scratchpad. Over 10 years of data retention. The 64kbit SRAM in the iButton is partitioned in 256 bit pages, with a total of 256 pages. The 64-bit factory lasered ROM: The Scorecard Logger The electronic hand-held battery driven Golf Scorecard Logger is for the player to bring along when a match is played. It interacts with the user through an LCD display and a keyboard.

Software The software consists of two areas, the scorecard logger software and the PC software. A part of the menu structure for the scorecard logger is illustrated. Through a structured approach the program code is created, using development tools such as Keil uVision for the Dallas 8051 processing unit, and Borland C++ Builder for the PC software.
