1-wire Slave Device Support

Last Updated: November 30, 2011

Can PSoC act as a 1-wire slave device while using the 1-wire user module?


Please note that PSoC can be used only as a One-wire master and cannot be used as a slave.  The One wire user module is a set of library routines that can read and write data as a master using the Maxim Integrated Products' 1-Wire protocol. Please refer our Application note

AN2163-Temperature Measurement with a 1-Wire Digital Sensor which implements the temperature measurement at 1degree Celcius resolution using a Dallas Semiconductor DS1821 digital temperature sensor with a 1-wire digital interface. It also shows how to implement a "1-Wire Bus Protocol" communication in 'C' programming language between slave and master devices using the one wire protocol.
