基于FDC2214的纸张计数显示装置的设计与实现

Design and Implementation of Paper Counting Display Device Based on FDC2214

本设计以STM32F407单片机为控制核心,通过电容传感器FDC2214实时检测两块电极板所组成的电容器的电容,与已录入单片机的电容值进行比对,达到测量出此时两极板内所夹的纸张数量的目的,同时将纸张数量测试结果显示在液晶屏上,具有准确度高,结构简单,制作成本低等特点。

This design takes STM32F407 as the control core, detects the capacitance of capacitors composed of two electrode boards in real time by capacitance sensor FDC2214, and compares the capacitance value with the capacitance value of the input single chip computer, so as to achieve the purpose of measuring the quantity of paper in the two electrode boards at this time. At the same time, the paper quantity test results show that On the LCD screen, it has the characteristics of high accuracy, simple structure and low production cost.
