Summary of DS1820 TEMPERATURE SENSOR CIRCUIT PIC16F84 ASSEMBLY
This project uses a PIC16F84 microcontroller in assembly to read a single Dallas DS1820 temperature sensor and display raw and high-resolution temperature data on a 2x16 (or larger) LCD. The LCD shows sensor family code, serial number, CRC status, scratchpad bytes, and high-resolution temperature. Full assembly source code, schematic, and related files (including a .cod file) are provided and demonstrated step-by-step in MPLAB.Parts used in the DS1820 Temperature Sensor Circuit PIC16F84 Assembly:
- Dallas DS1820 temperature sensor

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
