This application note introduces the user to the 1-Wire
®
communication protocol and describes how a 1-Wire
device can be interfaced to the PIC
®
microcontrollers.
1-Wire protocol is a registered trade mark of Maxim/
Dallas Semiconductor.
A software stack for the basic, standard speed, 1-Wire
master communication is provided with this application
note along with an example application. AN1199
1-Wire Communication with PIC Microcontroller
Author: Sashavalli Maniyar 1-Wire Protocol
Microchip Technology Inc. The protocol is called 1-Wire because it uses
1 wire to transfer data. 1-Wire architecture uses a
INTRODUCTION pull-up resistor to pull voltage off the data line at
the master side.
