在这个Arduino I2C 教程中,我们将使用两个 arduino 板之间的 I2C 通信,并使用电位器相互发送(0 到 127)值。值将显示在连接到每个 Arduino的16x2 LCD上。在这里,一个 Arduino 将充当 Master,另一个将充当 Slave。那么让我们从I2C通信的介绍开始。 什么是 I2C 通信协议? 术语IIC 代表“ Inter Inte
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(Master Reader/Slave Sender)。 Master Writer/Slave receiver:编程两个Arduino板之间通过I2C交流,另外一个设置为主写从收(Master Writer/Slave Receiver)。 SFR Ranger...

Begin a transmission to the I2C slave device with the given address. Subsequently, queue bytes for transmission with thewrite()function and transmit them by callingendTransmission(). Parameters address: the 7-bit address of the device to transmit to Returns None Wire.endTransmission()主机向从机传...
使用Arduino SoftI2C库进行IIC通信 #include"SoftI2C.h"myiic =SoftI2C(0,1);//定义iic对象,sda=0,scl=1myiic.begin();//初始化/***写数据***/myiic.beginTransmission(0x36);//1 向器件地址为0x36的从设备通信myiic.write(0x10);//2 向寄存器地址0x10写入数据myiic.write(0x3f);//3 写如数据0...
// Writes data to an I2C/TWI slave device // Refer to the "Wire Slave Receiver" example for use with this // Created 29 March 2006 // This example code is in the public domain. #include <Wire.h> void setup() { Wire.begin(); // join i2c bus (address optional for master) ...

wire.write()可以写成: wire.write(value)value:要作为单个字节发送的值。 wi 8、re.write(string):string:要作为一系列字节发送的字符串。 wire.write(data,length):data:要作为字节发送的数据数组length:要传输的字节数。4. wire.begintransmission(address):用途:该函数用于开始使用给定的从地址传输到i2c设备。
