## DESCRIPTION

### 1-Wire

*1-wire* is a wiring protocol and series of devices designed and manufactured by Dallas Semiconductor, Inc. The bus is a low-power low-speed low-connector scheme where the data line can also provide power.

Each device is uniquely and unalterably numbered during manufacture. There are a wide variety of devices, including memory, sensors (humidity, temperature, voltage, contact, current), switches, timers and data loggers. More complex devices (like thermocouple sensors) can be built with these basic devices. There are also 1-wire devices that have encryption included.

The 1-wire scheme uses a single  *bus master* and multiple *slaves* on the same wire. The bus master initiates all communication. The slaves can be  individually discovered and addressed using their unique ID.

Bus masters come in a variety of configurations including serial, parallel, i2c, network or USB adapters.

### OWFS design

*OWFS* is a suite of programs that designed to make the 1-wire bus and its devices easily accessible. The underlying principle is to create a virtual filesystem, with the unique ID being the directory, and the individual properties of the device are represented as simple files that can be read and written.

Details of the individual slave or master design are hidden behind a consistent interface. The goal is to  provide an easy set of tools for a software designer to create monitoring or control applications. There  are some performance enhancements in the implementation, including data caching, parallel access to bus  masters, and aggregation of device communication. Still the fundamental goal has been ease of use, flexibility and correctness rather than speed.

### EDS00XX Overview

The EDS00XX sensors are a family of devices from  *Embedded Data Systems.* Although provisional support for several types is included, only early *EDS0071* has been tested with *OWFS.*

The sensors all share the same  *7E* family code. They have the same first memory page layout with a text *tag* property that describes them, and a *sub-type* field giving the particular sensor. The data properties shown in a directory listing will be specific to the sensor *sub-type.*

### EDS0071

The **EDS0071 (3)** is a micro-processor based 1-wire slave made by EDS (Embedded Data Systams). Is uses a high accuracy and extended range RTD sensor to accurately measure temperatures.

### Memory

The *EDS00XX* sensors are read and controlled by accessing parts of their on-chip memory. Although the raw memory contents are exposed in the  *memory* and *pages* fields, all the available functionality is best accessed by the other fields. In fact, directly changing memory will confuse *OWFS.*

### Relay and LED

All the *EDS00XX* sensors have an LED and optional relay. Both can be controlled either directly, or when the sensors reaches an alarm state.

## ADDRESSING

All 1-wire devices are factory assigned a unique 64-bit address. This address is of the form:

- **Family Code**

  8 bits

- **Address**

  48 bits

- **CRC**

  8 bits

-

  Addressing under OWFS is in hexadecimal, of form:

-

  **01.123456789ABC**

where **01** is an example 8-bit family code, and **12345678ABC** is an example 48 bit address.

The dot is optional, and the CRC code can included. If included, it must be correct.
