為解決我國水位監測野外條件下長期無人看守的問題，研制開發了基于MSP430單片機的智能水位計。從其組成到各功能分別進行了詳細的介紹，該智能水位計不僅實現了水位數據的實時監測、記錄和定期采集等多種工作模式，而且提高了水位監測精度，實現了水位監測的智能化。
Abstract:
In order to solve the problems of long-term unmanned observation in the field water monitoring，an intelligence water-level meter based on MSP430 is developed composition and every function moduce of the water level meter was introduced in detail. It not only realizes water level data collection and storage， regularly gathering and so on， but also improves the water-level precision ， finally realizes the intelligence.
介紹一種以MSP430單片機為基礎的智能頻率測量系統，采用硬件邏輯與軟件指令相結合的方式控制閘門，實現0 MHz~10 MHz范圍內無檔切換的等精度測量。
Abstract:
An intelligent frequency measurement system based on MSP430 singlechip is introduced. The system uses a way that can combine hardware logic and software instructions to contronl the strobe ,and completes the functions of equal precision in the range of 0MHz~10MHz without shifting
