The AD7992 is a 12-bit, low power, successive approximation ADC with an I2C-compatible interface. The part operates from a single 2.7 V to 5.5 V power supply and features a 2 μs conver-sion time. The part contains a 2-channel multiplexer and track-and-hold amplifier

按键控制，检测独立按键，单片机读取状态口，控制相应的LED灯(Key control, testing the independent button, the microcontroller reads the status port and control the corresponding LED lights)

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.)
