用于超声波测距 程序是用于msp430的 放在msp430编译器建立工程项将本记事本 中的源码复制进去编译就可-Ultrasonic Ranging process is used for the msp430' s on the msp430 compiler works project will be to establish the source of this notebook can be copied into the build

基于msp430超声波测距程序-Msp430 ultrasonic ranging program

超声波测距程序，通过声波和高电平的时间来测量距离(Ultrasonic Ranging procedures, through the sound wave and high level of time to measure distance.It can be revised and perfected. MSP430F149 program.)
