水分测定仪的软件设计采用模块化的设计原则，以降低程序设计复杂度，便于编译的代码进行修改，使得代码的结构简单易读，利于后续的电路仿真。

水分测定仪系统上电后，MSP430对各个部分进行初始化操作，当无按键按下时，MSP430对采集到的数据进行数据预处理，并进行温度补偿和非线性校正等操作，而后在LCD界面显示称重的结果；当有复位的按键按下时，进入相应的子函数进行处理，处理完成后，要么返回，要么等待用户按键进行下级操作。即在按键按下时，对之前测得的质量数据进行清零，然后进行新一次的质量称量，并在LCD上进行所得数据的显示-Moisture determination instrument software design using modular design principles, in order to reduce the complexity of program design, easy to compile the code to be modified, the code structure is simple and easy to read, for subsequent circuit simulation.

Moisture measuring instrument system after power, MSP430 of each part of the initialization operation, when no button is pressed, MSP430 the collected data were data pre processing, and temperature compensation and nonlinear correction etc. operation and weighing results are displayed on the LCD interface　when a reset button is pressed into the corresponding function for processing, after completion of treatment, either return or wait for the user presses a key operation at a lower level. That is, when the button is pressed, the quality of the measured data were cleared, and then a new quality weighing, and the data on the LCD displa
