该程序实现了利用滑动变阻器的改变，在LCD上跟随显示当前A/D转换器件的转换值、转换后的电压值，电压值要求精确到小数点后两位。转换值要求用16进制数显示出来。(The program implements the use of sliding rheostat changes follow on the LCD displays the current A/D conversion device of the conversion value, the converted voltage value, voltage value required precision to two decimal places. Conversion value required is displayed with a hexadecimal number.)

开机自检、去皮、计价、清零、中文液晶显示等； 从上述中可以看出，本设计的主要思路是利用压力传感器得到重量的变化并且将重量的变化经过电压放大电路经过，A/D转换器将模拟量变换为数字量，单片机可以顺利的读取，并且将得到的信息进行采集后计算。通过累加之后的方式将物品的重量和价值总额，通过显示电路显示出来(Self-check, peel, price, clear, Chinese liquid crystal display and so on; It can be seen from the above, the main idea of this design is the change of the pressure sensors are used to get the weight and the weight change after the voltage amplification circuit, A/D converter analog conversion into digital quantity, single chip can be read smoothly, and to get information from the acquisition after calculation. The weight and total value of the item are displayed by means of the display circuit.)
