Abstract:This paper discusses a method of designing sample temperature data system by complex programmable logic device.The core of the whole system have been divided into two parts:temperature collection, LED display. The temperature collection controller based on complex programmable logic device, this system is based on MAX6627 precise digital temperature sensors report the temperature of a remote sensor and EPM3128ATC144.It
is more accurate mobility and in common use than others.It can communicate with PC when use high speed data transmission interface,then analyze and deal with these dates.
