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. ƒ Simple solution to add security or other device ƒ Standard iButton® and custom modules supported ƒ 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: ƒ iButton® and Advantech-Innocore's GPIO iButton® carrier ƒ Advantech-Innocore's DPX®-series mainboard ƒ 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 ƒ Rugged steel container allows for long term durability in harsh environments ƒ Extremely portable. Can be mounted in watches, rings, keychains etc. ƒ Self contained, requiring just one data and one ground connection to function ƒ Unique and unalterable address laser etched onto the chip inside the can ƒ Tamperproof. Chip erases itself if metal container is opened. Typical Application of the iButton® ƒ Store slot machine status information for easy retrieval by slot technicians ƒ Electronic ID can provide access control to hardware ƒ E-cash and player tracking system ƒ Unique ID’s and encryption to lock software against cloning ƒ RTC (Real – Time – Clock) to control time-restricted licensing in game titles 1-wire® bus security module
