+Gravity 3.7V锂电池电量计使用Gravity I2C接口，超低工作电流，通过Maxim专利算法，实时跟踪电池的相对充电状态(SOC，State-Of-Charge)，无需充放电学习过程，无积累误差，即插即用，准确地测量锂电池的当前电压和剩余电量。模块预留低电量报警中断引脚，当电池电量低于指定电量时，该引脚产生一个下跳脉冲，触发主控的外部中断。

+## 概述
+
+提供 Arduino 库，用于通过 I2C 读取和解释 MAX17043 数据。
+
+## 连接
+相同颜色的线连接在一起，我们只举例说明主板是如何连接到电量计的。接线时要注意管脚的对应关系，接线图如下：

+
+
+## 库安装
+
+这里有2种安装方法：
+1. 使用此库前，请首先下载库文件，将其粘贴到\Arduino\libraries目录中，然后打开examples文件夹并在该文件夹中运行演示。
+2. 直接在Arduino软件库管理中搜索下载 DFRobot_MAX17043 库
