Ultrasonic Distance Measurement With the MSP430

基于低功耗单片机MSP430的实现超神波测量距离的程序。-Based on low-power single-chip implementation of the MSP430 ultra-god-wave distance measuring procedures.

The devices used to transmit and receive the ultrasonic sound waves in this application are 40-kHz ceramic ultrasonic transducers. The MSP430 drives the transmitter transducer with a 12-cycle burst of 40-kHz square-wave signal derived from the cr
