Title DESIGN OF DIGITAL THERMOMETER BASED ON MSP430F1612
Abstract
With the development of science and technology, temperature measurement in industrial production status is growing, and can perform temperature monitoring system has also been applied to all aspects of both cost savings and can therefore stable working system has been gaining popularity.Digital thermometer reads the temperature can be effectively applicable to all aspects of industrial production, but also has high reliability, good controllability, stable, low power consumption, and many other advantages, is one of the most cost-effective choice.MSP430F1612 is a 16-bit microcontroller, using a reduced instruction set (RISC) architecture, has a wealth of addressing modes, simple 27 core instruction and a large number of simulation instruction, a large number of registers and on-chip data memory can participate in multi-kinds of operation, as well as efficient processing instruction look-up table. It computing speed, processing capacity, the development of simple equipment, easy to program, easy to operate, suitable for a variety of designs.This design uses DS18B20 sensors and MSP430F1612 microcontroller development, applied to the mold digital circuit, microcontroller programming and measurement as well as other aspects of comprehensive knowledge, according to the design requirements, the completion of system design, complete digital temperature sensor temperature acquisition conversion, etc. , while the design of related systems RS232/RS485 serial communication circuit, complete the data remote control.
This design uses Protel99 for circuit design, use IAR430 debugging software, these two software performance, simple operation, in which each module can be developed and implemented.
