Title Multi-channel temperature acquisition system Hardware dedign based on MSP430 single chip microcomputer
Abstract
Temperature measurement,utilized everywhere,not only in the field of agriculture and industry, but also in civilian areas, military areas.This project will complete Multi-channel temperature acquisition system Hardware design based on MSP430, mainly to complete the hardware design part of this system.In the meantime, core chip software control program was wrote to complete the temperature acquisition,as well as the task of communication with computer.First of all, C language was used to write the software program through IARC430 compiler.And then, the feasibility of this program was verified by proteus hardware simulation.in the last , Schematics, Printed Circuit Board and 3DPCB were completed through Altium Designer 09.Finally, core chip control program was completed and verified by proteus,the task of PCB design also was completed.
Keywords: MSP430SCM temperature acquisition DS18B20 PCB
