1. Golf Scorecard Logger Supervisor: Alan Edgar Napier University Introduction: To automate and ease the scorekeeping of golf players matches for calculation of individual handicap scores and statistical illustration, a hand-held electronic scorecard logger unit is developed, with the implementation of the 1-Wire bus and 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 the scores, where improvement can be tracked.

2. iButton Implementation Features of the DS1996 iButton:  64kbit nonvolatile memory.  142kbit/sec communication.  64 bit unique ROM registration number  256 bit scratchpad.  Over 10 years of data retention. 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. The 64kbit SRAM in the iButton is partitioned in 256 bit pages, with a total of 256 pages. The 64-bit factory lasered ROM: iButton reader at the Scorecard Logger:

3. 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. Hardware Block Diagram: For the hardware a PCB is designed using Surface Mount Technology (SMT) to make it compact enough to fit in the chosen enclosure and optimize the power consumption. The circuit is created with the desire of a high quality and upgradeable result, regarding the software and future work. The Golf Scorecard Logger:

4. Software More info: www.ck-electronic.dk/gsl 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.
