With the continuous development of science and technology and the changes of the times, electronic scales have become an indispensable measuring tool in our daily life. The electronic scale is composed of the design and development of weigh module, ADC chip, MCU main control chip, button module and display module. When the object is placed on the scale, the pressure sensor in the weigh module obtains the information of the weighing object, and the ADC chip converts the analog signal into a digital signal. The MCU main control chip controls the normal operation of the button module and the display module, so we have the range display we see on the LED screen of the electronic scale. The following is an introduction to the core component of the electronic scale solution - the MCU main control chip
