如何查詢I2C位址

操作流程

STEP 1. 將欲查詢的模組連接至Arduino UNO（附圖為腳位參考，實際請比對商品標示接線）

STEP 2. 開啟Arduino IDE並新增檔案

STEP 3. 貼入教學下方的範例文件，並上傳到Arduino UNO，即會開始掃描I2C位址

STEP 4. 開啟序列埠監控視窗，即可取得I2C位址

I2C掃描範例程式

/ ---------------------------------------------------------------- /

// Arduino I2C Scanner

// Re-writed by Arbi Abdul Jabbaar

// Using Arduino IDE 1.8.7

// Using GY-87 module for the target

// Tested on 10 September 2019

// This sketch tests the standard 7-bit addresses

// Devices with higher bit address might not be seen properly.

/ ---------------------------------------------------------------- /

#include //include Wire.h library

void setup()

{

Wire.begin(); // Wire communication begin

Serial.begin(9600); // The baudrate of Serial monitor is set in 9600

while (!Serial); // Waiting for Serial Monitor

Serial.println("\nI2C Scanner");

}

void loop()

{

byte error, address; //variable for error and I2C address

int nDevices;

Serial.println("Scanning...");

nDevices = 0;

for (address = 1; address < 127; address++ )

{

// The i2c_scanner uses the return value of

// the Write.endTransmisstion to see if

// a device did acknowledge to the address.

Wire.beginTransmission(address);

error = Wire.endTransmission();

if (error == 0)

{

Serial.print("I2C device found at address 0x");

if (address < 16)

Serial.print("0");

Serial.print(address, HEX);

Serial.println(" !");

nDevices++;

}

else if (error == 4)

{

Serial.print("Unknown error at address 0x");

if (address < 16)

Serial.print("0");

Serial.println(address, HEX);

}

if (nDevices == 0)

Serial.println("No I2C devices found\n");

else

Serial.println("done\n");

delay(5000); // wait 5 seconds for the next I2C scan

}
