Choosing the Right 1-Wire® Master for Embedded Applications
This application note presents four categories of 1-Wire master circuits for embedded applications and discusses their capabilities and requirements in relation to available (i.e., unused) system resources. The schematics shown here apply to short networks that do not extend beyond the radius of 1 meter and are populated with a small number of 1-Wire slaves. Instructions and a decision worksheet are included to identify the most cost-effective 1-Wire master for the application. The reader should be familiar with the basics of 1-Wire communication and microcontrollers.
