one-wire-ds2482

This crate provides a driver for the DS2482, a I2C to 1-wire bridge. It is an implementation of the OneWire trait from the one-wire-hal crate.

Note

This project is a work in progress and might not yet ready for use. This crate is not yet published on crates.io.

The particular device used for implementation is the DS2482-100, but the driver should work with other devices in the DS2482 family.

Datasheet: DS2482-100

Usage

Setup the one-wire bus with the DS2482 and search for devices:

// setup one-wire bus
let mut ds2482 = OneWireDS2482::new(i2c, 0x18);
ds2482.ds2482_device_reset().unwrap();
ds2482.ds2482_write_config(0b0001).unwrap();
let mut one_wire = ds2482;

// search for devices
let mut devices = one_wire.devices(delay);

To Do

• Write tests for OneWireDS2482
• Publish the crate
• Add documentation
• Add working examples for popular devices like the DS18B20
• Update cortex-m dev dependency as soon as it is compatible with embedded-hal:1.0
• Add github actions for CI
