一种基于MSP430单片机的超声波测距系统的设计与实现OA
根据在空气中超声波传播速度固定的特点,通过记录单片机中计数器数值来计算超声波的传播时间,时间与速度相乘得到距离值为原理,设计了一种由MSP430F1101单片机控制的超声波测距系统,系统具有易实现、实时性、可靠性和适应性好等特点。
According to the air of ultrasonic velocity are fixed,through numerical MCUcounter records to calculate the propagation time of ultrasonic wave,time and speed?has been multiplied by distance value principle,designed a kind ofultrasonic ranging system controled by MSP430F1101 MCU,system has the features of easy realization,real-time,reliability and good adaptability etc.
