1-Wire Temperature Control
Original Web address: **broken link removed**
This free project was designed to measure and control temperature in the range of - 55°C to +125°C with 0.1°C accuracy. It is based on the popular PIC16F628A microcontroller of Microchip. The microcontroller uses the 1-Wire protocol ( sometimes known as a MicroLAN ) to communicate with a DS18B20 digital thermometer and a DS2405 addressable switch. The 1-Wire bus requires only one data line (and ground) for communication with a central microprocessor .The PIC16F628A chip implements several basic functions, such as an ON-OFF controller function, driving a LED display, reading and writing all 1-Wire devices. In addition, the controller can be fully configured and monitored from any Windows 9x , ME , NT , 2000 or XP PC via RS-232C serial port using an interface application. An overview of the main components is shown in figure 1.
