Unless I overlooked it they have little in the way of 8051 or C code that will determine part ID'S. They have everything you need there! http://www.maxim-ic.com/1-Wire.cfm All the App Notes & Tutorials are here: http://www.maxim-ic.com/an_prodli...rodline/21 The one you specifically require is: APPLICATION NOTE 187, 1-Wire Search Algorithm: Dallas Semiconductor's 1-Wire® devices each have a 64-bit unique registration number in read-only-memory (ROM) that is used to address them individually by a 1-Wire master in a 1-Wire network. If the ROM numbers of the slave devices on the 1-Wire network are not known, then using a search algorithm can discover them. This document explains the search algorithm in detail and provides an example implementation for rapid integration. This algorithm is valid for all current and future devices that feature a 1-Wire interface. http://pdfserv.maxim-ic.com/en/an/app187.pdf Peter Danneger on this forum has also published a simplified search algorithm - use this forum's 'Search' button. You should also red Guidelines for Reliable 1-Wire Networks http://www.maxim-ic.com/appnotes....number/148 APPLICATION NOTE 162 Interfacing the DS18X20/DS1822 1-Wire Temperature Sensor in a Microcontroller Environment contains the necessary 'C' source code http://pdfserv.maxim-ic.com/en/an/app162.pdf and so on... |
