摘要：

The system introduces the composition of the ultrasonic distance measuring system based on S3C2410 and gives the operation principle and procedure design method. The module of temperature compensation circuit has been added to hardware circuit to improve the precision. S3C2410 drive transducer sent a 40kHz square wave signal, opening the external interrupt and triggerring timer interrupt, The external interrupt receive echo signal immediately triggerring the timer to obtain ranging value. The ranging value is real-time displayed through the LCD. The structure of ultrasonic measuring module driver program is analyzed in embedded Linux system. The system can be used for the distance measurement parameters needed for a variety of application occasions.
