单片机传感器模块开发实例-DS18B20温度传感器(C51、Arduino、KEIL、原理图、文档）

Arduino Library for Dallas Temperature ICs ========================================== Usage ----- This library supports the following devices : * DS18B20 * DS18S20 - Please note there appears to be an issue with this series. * DS1822 You will need a pull-up resistor of about 5 KOhm between the 1-Wire data line and your 5V power. If you are using the DS18B20, ground pins 1 and 3. The centre pin is the data line '1-wire'. We have included a "REQUIRESNEW" and "REQUIRESALARMS" definition. If you want to slim down the code feel free to use either of these by including #define REQUIRESNEW or #define REQUIRESALARMS at the top of DallasTemperature.h Credits ------- The OneWire code has been derived from http://www.arduino.cc/playground/Learning/OneWire. Miles Burton <miles@mnetcs.com> originally developed this library. Tim Newsome <nuisance@casualhacker.net> added support for multiple sensors on the same bus. Guil Barros [gfbarros@bappos.com] added getTempByAddress (v3.5) Rob Tillaart [rob.tillaart@gmail.com] added async modus (v3.7.0) Website ------- You can find the latest version of the library at http://milesburton.com/index.php?title=Dallas_Temperature_Control_Library License ------- This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version.
