OneWire

This group of functions allows connections of Maxim 1-Wire devices to the RTCU device.

1-Wire is a simple and very easy to implement serial bus. It consists of only two wires (Signal and GND) and makes it very easy to implement remote sensing in various applications.

Currently, direct support for iButton and temperature sensors is implemented, and support for additional devices can be added by using the generic OneWire functions.

	•iButton	Functions for working with iButton.
	•Temperature	Functions for working with temperature sensors.

Generic OneWire functions:

Generic one-wire has support for working with all devices on the bus and for only working with alerted devices:

	•Alarm	Functions for working with alerted devices:
	•Generic OneWire	Functions for working with all devices.

The implementation of OneWire has the following limitations:

•It is only possible to read/write to the last iButton discovered with owiButtonGetID.
