CaddieON electronic golf-play analyzer designed by CaddieON help golf players to automatically track and analyze their golf playing method and style. This wrist-watch like device uses RFID tags for identifying each club, the smartphone app, and a player portal in cloud service.
This device is designed using STMicroelectronic's STM32L1 microcontroller and MEMS sensor chips. It reads each club’s tag and automatically records the round stroke by stroke, and sends data to the app via Bluetooth. ST's RFID reader IC is used for identifying tagged clubs, a tiny single-chip accelerometer for accurate stroke detection, and an ultra-low-power microcontroller for system control.
“ST’s proven technologies, easy-to-use development tools, and competitive pricing helped us overcome tough budgetary and time-to-market constraints, and achieve a successful result,” said Tuomo Lalli, founder and CEO of CaddieON. “CaddieON will greatly enhance enjoyment of the game for golfing devotees worldwide. I should know, because I am one.”
“CaddieON is cutting-edge in so many ways, not only in technological terms but also in its use of crowd funding and incentives for customers to help map large numbers of popular golf courses around the world,” said Iain Currie, Vice President North Europe Sales, STMicroelectronics. “Our advanced low-power and sensing technologies are perfect for an innovative project like this.”
The CaddieON wrist device uses ST’s CR95HF integrated transceiver IC for reading the RFID tags attached to each of the player’s clubs. The CR95HF manages frame coding and decoding for standard contactless applications. It supports ISO/IEC 14443 Type A and B, ISO/IEC 15693 and ISO/IEC 18092 protocols, and also embeds an analog front end (AFE) to provide the 13.56MHz air interface. It can also detect, read and write NFC Forum Type 1, 2, 3 and 4 tags.
ST LIS3DSH ultra low-power high-performance three-axis linear accelerometer used in this device operates from a supply voltage as low as 1.71V, and has a dynamically selectable full scale of up to ±16g. It can be configured to generate interrupts according to user-defined movement patterns, and integrates a programmable state machine as well as a FIFO buffer that helps reduce host-processor intervention. It is housed in a tiny 3mm x 3mm x 1mm thin plastic land grid array package (LGA).
