摘要
基于32位超低功耗ARM Cortex-M3微处理器,利用其运算速度高等优点应用于超声测距。对超声波测距进行理论研究和验证、软硬件设计、整机调试,达到了预定的设计目标,完成了对水位的精准测量,并可与其他设备或PC实现RS485通信。
Base on 32-bit ultro-low-power Microcontroller,by high speed the water level meter gets the distance from the probe to the water level.It accomplishes the research in theory,the design in hardware and software,the system debugging.It ac-complishes to precisely measure the water lever.It communicates by RS485 protocol with other device or PC.
