BMX160+BMP388 Address Problem

Hello,

thank you for your answer. I scanned it and this is the output (not welded):

Scanning...

I2C device found at address 0x68  !

I2C device found at address 0x76  !

done

If i weld it to change the address its:

Scanning...

I2C device found at address 0x69  !

I2C device found at address 0x76  !

done

So its changing but while initialising its only working for 0x68. I need to make it work with 0x69.

Much thanks

Hello,

Have you tried to use an I2C scanning program to check the changed I2C address? If you are using Arduino IDE, you can try the following code. 

#include <Wire.h> // Include the Wire library for I2C communication

// Setup function initializes the serial communication and I2C
void setup() {
 Serial.begin(9600); // Initialize serial communication with a baud rate of 9600
 Wire.begin(); // Initialize the I2C communication
 
 Serial.println("Start I2C address scan"); // Print a message to indicate the scan is starting
}

// Loop function continuously scans for I2C devices
void loop() {
 byte device_address; // Variable to store the I2C device address
 int nDevices; // Variable to store the number of devices found

 // Search for devices on the I2C bus
 nDevices = Wire.scan(); // Perform the scan and store the number of devices found

 // Print the number of devices found
 Serial.print("Number of devices found: ");
 Serial.println(nDevices);

 // Loop through all the devices found
 for (int i = 0; i < nDevices; i++) {
   // Get the address of the current device
   device_address = Wire.getDeviceList();

   // Print the device address
   Serial.print("Device address: ");
   Serial.print(device_address, HEX); // Print the address in hexadecimal format
   Serial.println(" (0x"); // Print a prefix to indicate hexadecimal format
 }

 // Wait for a few seconds before scanning again
 delay(5000);
}
