Key Features
- 1-Wire® Protocol: Requires only a single data lead and a ground return.
- Unique 64-bit ROM Registration Number: Guarantees a unique node address in the 1-Wire network.
- Standard or Fast Data Transfer: Interfaces directly to I2C slaves at standard (100kHz max) or fast (400kHz max).
- Compact Size: The click board size is S (28.6 x 25.4 mm), making it highly portable and convenient.
Introducing the Revolutionary 1-Wire I2C Click!
Unleash the Power of DS28E17 1-Wire-to-I2C Master Bridge!
Are you looking to extend the length of your I2C lines effortlessly? Discover the groundbreaking 1-Wire I2C click, featuring the DS28E17 1-Wire-to-I2C master bridge from Analog Devices! This innovative device is your ticket to seamless communication with microcontrollers over the 1-Wire® protocol, using the mikroBUS™ line: AN, PWM, RST.
The 1-Wire I2C Click Board™ carries the DS28E17 1-Wire-to-I2C master bridge from Maxim Integrated. The click runs on a 3.3V power supply.
It communicates with the target microcontroller over 1-Wire® protocol, using the following pins on the mikroBUS™ line: AN, PWM, RST.
How Does The 1-Wire I2C Click Board™ Work?
There are two on-board screw terminals used for connecting SCL, SDA, Vcc and GND of the I2C slave. After that, you are able to communicate with that slave through the onboard DS28E17 MCU.
DS28E17 FEATURES
The DS28E17 is a 1-Wire slave to I2C master bridge device that interfaces directly to I2C slaves at standard (100kHz max) or fast (400kHz max). Data transfers serially through the 1-Wire® protocol, which requires only a single data lead and a ground return. Every DS28E17 is guaranteed to have a unique 64-bit ROM registration number that serves as a node address in the 1-Wire network.

CODE SNIPPET
The following code snippet shows 1-Wire I2C click communication with the Thermo 4 click. It uses skipRom, writeI2C, and readI2C commands to read the temperature data from the sensor, and displays it back via UART output.
01 void One_Wire_I2C_Task()
02 {
03 char uartText [20];
04 char IWireData [20];
05
06 IWireData [0] = 0x00; //Thermo 4 temperature register address
07
08 OWI2C_skipRom ();
09 OWI2C_writeI2C ( OWI2C_WRITE_NORMAL_NOSTOP, 0x48, 1, &IWireData); //0x48 is unshifted I2C address of Thermo 4 click
10 OWI2C_skipRom ();
11 OWI2C_readI2C ( 0x48, 2, &IWireData);
