The Simple Sensor Application Kit provides sample applications based on 1-Wire devices to help users better understand and implement the 1-Wire communications bus using a prototyping board and a RabbitCore® module.
1-Wire provides a combination of memory, mixed signal and secure authentication functions via a single contact serial interface that delivers both power and communication on a single line (plus ground as a reference). 1-Wire offers a simple, low-cost solution for adding multiple system functions with a minimum number of interconnections. Sensors can send the data via 1-Wire to a microprocessor-based Rabbit module to initiate control functions, such as turning on heaters, air conditioners, fans or any other action.
The Simple Sensor Application Kit provides an ideal design reference to interface a Rabbit-based system to a Maxim-Dallas 1-Wire® bus. The kit provides sample applications based on four 1-Wire devices to help users better understand and implement a 1-Wire bus using a Prototyping Board and a RabbitCore® RCM4300 module. The Simple Sensor Kit is the ideal reference on how to interface any 1-Wire device to any Rabbit module or processor. The 1-Wire interface is still widely used and is best suited where ZigBee networks are not reliable due to environmental constraints or if the distance between two points is very short.

| OW_RWB.C | This sample program illustrates how to detect and manage 1-Wire devices via a Web interface using Dynamic RabbitWeb scripting and Yahoo! User Interface (YUI) libraries. |
| OW_RWB_LOG.C | This sample program is similar to OW_RWB.C, but also uses the miniSD Card on the RCM4300, and will create a 1-Wire folder on the miniSD Card with subfolders for each of the supported 1-Wire device types. |
Using the Dynamic C integrated development environment and RabbitWeb, you can create HTML forms for web pages that interface with C variables in embedded networked applications. The capability can reduce weeks or months of complex Common Gate Interface (CGI) programming down to hours and eliminate all of the C programming involved in parsing HTML form input and generating HTML pages based on program variables.
RabbitWeb is included in Dynamic C and is extremely useful for anyone planning or considering a web browser interface to monitor, control or configure their networked embedded application.
The kit provides seven application-level sample programs that demonstrate how to write applications that call and use the device function calls at the library level. These sample programs demonstrate common event loop processing for device I/O functions, and may be used as a basis to develop your own applications.
The DS2406 Dual Addressable Switch Plus Memory offers the ability to remotely control a pair of open drain transistors and to monitor the logic level at each transistor's output via the 1-Wire® bus for closed loop control.
DS18B20The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.
DS2450The DS2450 1-Wire® Quad A/D Converter is based on a successive-approximation analog-to-digital converter with a four to one analog multiplexer.
DS2480BThe DS2480B is a serial port to 1-Wire® interface chip that supports regular and overdrive speeds. It connects directly to UARTs and 5V RS232 systems
