GPIO/iButton® Introduction Advantech-Innocore's DPX®-Series boards have a GPIO header that is a very flexible multi-purpose interface that can be used to connect a variety of simple one- or two-wire devices. The Dallas iButton® is one such device and iButton devices are available for a number of different functions. The GPIO interface supports any 1-wire® bus device and typical uses could include special purpose I/O, security, memory and data storage. Simple solution to add security or other device Standard iButton® and custom modules supported Supplied driver and SDK Feature Summary Easy to use and robust mounting for up to two devices per GPIO board iButton(s)® are securely attached to the header Header is mounted to the motherboard by simple bracket which picks up on one of the motherboard mounting points How Does The iButton® Work? Up to two iButtons ® can be fitted to a DPX ® mainboard using a secure carrier board. In general the following components are needed for any iButton® application: iButton® and Advantech-Innocore's GPIO iButton® carrier Advantech-Innocore's DPX®-series mainboard Software to interface the iButton® to the DPX® board. Advantech-Innocore provides both Linux and Windows® builds of the 1-Wire API. Advantech-Innocore also provides software samples as well as utilities to aid the software development process Key iButton® Features Rugged steel container allows for long term durability in harsh environments Extremely portable. Can be mounted in watches, rings, keychains etc. Self contained, requiring just one data and one ground connection to function Unique and unalterable address laser etched onto the chip inside the can Tamperproof. Chip erases itself if metal container is opened. Typical Application of the iButton® Store slot machine status information for easy retrieval by slot technicians Electronic ID can provide access control to hardware E-cash and player tracking system Unique ID’s and encryption to lock software against cloning RTC (Real – Time – Clock) to control time-restricted licensing in game titles 1-wire® bus security module
