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

// 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.

Serial.println("No I2C devices found\n");
else
Serial.println("done\n");
delay(5000); // wait 5 seconds for the next I2C scan
