the master has to refer to each slave using a different address. When addressed only the slave with that particular address will reply back with the information while the others keep quit. This way we can use the same bus to communicate with multiple...
打开"文件"->"示例"-> "Wire"-> "slave_sender"。然后点击 "项目"->"上传",编译并上传示例到 Arduino Uno。设置BW21-CBV-Kit 为 I2C 主机接下来,打开 Arduino IDE 的另一个窗口,确保在 IDE 中选择 BW21-CBV-Kit 开发板:"工具"->"开发板"。打开"文件"->"示例"->"AmebaWire"->"MasterReceiveData"...
When the I2C slave receives a string sent from I2C master, it prints the received string. Setting up Arduino Uno to be I2C Slave First, select Arduino in the Arduino IDE in “Tools” -> “Board” -> “Arduino Uno” Open the “Slave Receiver” example in “Examples” -> “Wire” ->...
总结:Arduino作为I2C slave与树莓派交谈是一种常见的硬件通信方式,可以用于传感器数据采集、执行器控制和外设扩展等应用场景。通过I2C协议,Arduino可以与树莓派进行可靠的数据交换。

begin 函数用于初始化 Wrie Library 并以 Master 或 Slave 的身份加入 I2C 总线上。begin 函数没有返回值。调用 begin 函数有两种形式: begin():无输入参数,表示以 Master 形式加入总线。 begin( address ):有输入参数,表示以从机形式加入总线,设备地址为address(7-bit) ...
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 Reader: 通过I2C读取超声波测距仪接口。
// Reads data from an I2C/TWI slave device // Refer to the "Wire Slave Sender" 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) ...
