OneCable

onecable implements (parts of) the 1-Wire protocol, with a specific focus on the DS18B20 temperature sensor.

onecable is no-std, enabling it to run on any hardware for which the embedded_hal traits are implemented.

1-Wire

For further information on the 1-Wire protocol, look at the Book of iButton® Standards. For additional information on the DS18B20 sensor, have a look at its datasheet.

OneCable

onecable is an implementation of the 1-Wire protocol, and is currently focussed of supporting the DS18B20 temperature sensor.

How to use?

First, create a OneWire instance with OneWire::new, then you can discover the ROM codes of the connected devices with e.g. OneWire::search_rom_iter. If you have only one device connected to the OneWire bus, you can also use OneWire::read_rom to read the ROM code of that device.

Once you have a valid ROM code, you can convert it to a DS18B20 sensor instance with ds18b20::DS18B20::try_from.
