High Precision Electronic Scale Design Based on MCU

This paper introduces a design of the High Precision Electronic Scale Design Based on MCU, Hardware circuit reaches data processing by the control unit which based on MCU, and The MCU gathers data by weighting sensor, then the LM331 makes V/F transform, and the transformed data then transferred to MCU for display processing. At last, the LCD would show it out steadily without twinkling. The paper mainly puts forward the scheme and software design idea, hardware design.
