秤是现在生活中必不可少的一个物件，可称体重，也可以用来衡量物体的价格。随着社会的进步，秤的种类繁多，像超市内的电子秤都要求带计价功能，对称的精准度都要求极高，因此传统的机械称逐渐被电子秤所取代，所以我们要以此为目的设计一款基于STM32单片机的电子秤系统。相比于计量不精确，费时费力的机械称，电子秤在采用方便快捷的同时，又保证了其准确性。设计中电子秤的处理器为STM32单片机来控制各个传感器和外设，显示器为LCD1602液晶屏来显示检测到的重量，压力传感器用于称重，通过检测物体对传感器造成的压力，通过公式计算得出物体的重量，并且通过16个按键组成矩阵键盘可以输入数字，并进行加减乘除操作，通过重量和单价计算出总价，然后语音播报。本设计优化了测量的精准度，用低功耗芯片降低了电路的损耗，同时增加了去皮和语音功能。

Scale is now an indispensable object in life, can weigh, can also be used to measure the price of objects. With the progress of society, there are many kinds of scales. For example, electronic scales in supermarkets are required to have pricing function, and the accuracy of symmetry is extremely high. Therefore, the traditional mechanical scales are gradually replaced by electronic scales, so we want to design an electronic scale system based on STM32 MCU for this purpose. Compared with the inaccurate measurement, time-consuming and laborious mechanical scale, the electronic scale is convenient and fast, while ensuring its accuracy. In the design, the processor of the electronic scale is STM32 single chip microcomputer to control each sensor and peripheral, the display is LCD1602 liquid crystal screen to display the detected weight, and the pressure sensor is used for weighing. By detecting the pressure caused by the object on the sensor, the weight of the object is calculated through the formula, and the matrix keyboard is composed of 16 keys to input numbers, The total price is calculated by weight and unit price, and then broadcast by voice. This design optimizes the accuracy of measurement, reduces the circuit loss with low-power chip, and increases the functions of peeling and voice.<br>
