| Abstract: | Based on the intrinsic hardware features of C8051F020,presented a new method of measuring and controlling system environment temperature,which is realized through making use of software and hardware.By appropriately analysing digital signals and realizing values conversion in the method,it can result in a satisfying measurement and control.Adopted the ADC programming window detector based on hardware for alarming irregular values,and consequently the system real-time performance was improved.Moreover,apply various control modes of cooling fan,and therefore take further step to raise the practical value of the C8051F020 chip on temperature measurement and control. |
