Take a look at UMPS, and load DS1820 example for 16C84, there is a small program (non optimized) to compute a 8-bit DOW CRC. UMPS demo is downloadable from: http://www.sistudio.com/umps You will find more information browsing the Application note 27 from DALLAS Semiconductor available from their web site: http://www.dalsemi.com Regards, Philippe. +--------------------------------------------------------+ | Virtual Micro Design | | Technopole Izarbel, | | 64210 BIDART | | FRANCE | | | | Phone: ++33 559.438.458 Fax: ++33 559.438.401 | | | | E-Mail: p.techer@idls.izarbel.tm.fr | | URL: http://www.sistudio.com/umps | +--------------------------------------------------------+
