Wire Library 允许通过两线接口总线连接的设备或传感器之间的通信,更多的信息参考the Reference for the Wire Library page。适用于所有的Arduino板,Arduino DUE除外。 Digital Potentiometer: 控制一个模拟设备AD5171数字电位器。 Master Reader/Slave Writer: 编程两个Arduino板之间通过I2C交流,另外一个设置为主读从写(...

Arduino 的封装库真的是非非非常的棒,I2C 就只有 10 个 API 函数。I2C 所用的库,称为:Wire Library。详细的描述可以看这个官方地址: https://www.arduino.cc/en/Reference/Wire 下面我会介绍部分的 API 函数。 ##begin begin 函数用于初始化 Wrie Library 并以 Master 或 Slave 的身份加入 I2C 总线上。beg...

Arduino Wirecompatible library, supporting I²C, I2C, IIC and/or (Two Wire Interface) TWI for Atmel ATTiny microprocessors utilizing the Universal Serial Interface (USI). This library proviedes Master and Slave functionality. Installation
The standard I2C library for the Arduino is the Wire library. While this library is sufficient most of the time, there are situations when it cannot be used: the I2C pins A4/A5 (or SDA/SCL) are in use already for other purposes same I2C addresses devices are used ...

在Arduino IDE 中点击「Sketch」—「Include Library」—「Manage Libraries」,查找「LiquidCrystal_I2C」,选择最新版本进行安装。 连接电路 IIC 转接板的 VCC、GND 分别连接开发板 5V、GND,转接板的 SDA、SCL 连接开发板 A4、A5。 编程 新建Sketch,拷贝如下代码替换自动生成的代码并进行保存。
本程序扫描从0-127的全部I2C地址,扫描数据从串口输出,扫描完成,13脚灯会闪动三次:#include "Wire.h" extern "C" { #include "utility/twi.h"// from Wire library, so we can do bus scanning } byte start_address = 1; byte end_address = 127; ...
Why another I2C library? The standard I2C library for the Arduino is theWire Library. While this library is sufficient most of the time when you want to communicate with devices, there are situations when it is not applicable: the I2C pins SDA/SCL are in use already for other purposes, ...
