DS1820 sensor designed for use with assembly language PIC16F84 on a circuit board data is displayed via 2 x 16 LCD mplab working on the code you can see step by step. cod file, including all source code available
Temperature Sensor Schematic
DS1820 Reader This code reads a single dallas DS1820 temperature sensor and displays both the raw data, and the high resolution temperature on the LCD. (2 lines x 20 characters, or larger, character display) for example
The first line on the LCD is the family code (10) and serial number with a CRC byte + either a tick if the CRC is right or cross if the CRC is wrong. The second line on the LCD gives data bytes 0, 1, 6 & 7 of the scratch pad and either the high resolution temperature & tick to show the CRC is correct or only a cross to show the CRC is wrong
