The data is displayed on a multi-page LCD display for immediate viewing as well as being sent via RS232 at 19200 baud for recording. Data is time-stamped with an optional on-board 1-Wire real time clock.</p> <p><a href="http://www.uelectronics.info/multitherm" target="_blank">read more</a></p> ARM 1-Wire ATMega168 DS1820 Thermometer Tue, 16 Sep 2008 17:04:15 +0000 admin 346 at http://www.uelectronics.info http://www.uelectronics.info/thermometer-ds1820-attiny15 <p>This is my very first construction with the cheap Atmel's <span class="contextlinks contextlinks-external"><span class="contextlinks-text"><a href="http://www.atmel.com/dyn/products/product_card.asp?part_id=2033" rel="CONTEXTLINKS_NEW_WINDOW">ATtiny15</a></span> <a href="http://www.atmel.com/dyn/products/product_card.asp?part_id=2033" rel="CONTEXTLINKS_NEW_WINDOW"><img src="/modules/contextlinks/images/external.gif" alt="external" /></a></span> and the <span class="contextlinks contextlinks-external"><span class="contextlinks-text"><a href="http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2815" rel="CONTEXTLINKS_NEW_WINDOW">DS1820</a></span> <a href="http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2815" rel="CONTEXTLINKS_NEW_WINDOW"><img src="/modules/contextlinks/images/external.gif" alt="external" /></a></span> thermometer. The main goal was the BIG display from the 7-segment LED modules.
