How To Connect Multiple I2c Devices Raspberry Pi Raspberry
This guide goes more in depth on working with multiple copies of the same I2C device, which most likely have the same I2C address.Getting this general configuration working seems to be a common source of confusion. As mentioned in the guide linked above, every I2C device on the I2C bus needs to have a unique address.If you've only used a single I2C device, you may not even have realized this.

4 EDIT: Other people I've talked to and one poster here (since deleted) have said that they have the same issue while going through the Instructables tutorial to set up multiple I2C busses. There are also multiple comments on the Instructables describing the same issue. So something is wrong with the tutorial.

sudo apt-get install i2c-tools. And then to run a scan, use i2cdetect with the following command line parameters: Download File. Copy Code. i2cdetect -y 1. On modern Raspberry Pi OS releases, you do not need to run the command with sudo. The -y disables interactive mode, so it just goes ahead and scans. The 1 specifies the I2C bus.

Step 1: Some Shell Comands Connect one of your i2c devices while your raspberry pi is of, start your raspberry pi and run sudo i2cdetect -y 1 You will see a table like in the attach figure. I have attach a BMP280 temp and barometric pressure sensor. The i2c address is 0x76 according to the table. Note this address. Do this for all your i2c devices.

Setting Up I2C Serial Communication on Raspberry Pi
To get around multiple I2C devices same address problem, there are two general methods (a) hardware multiplexer, (b) multiple I2C buses. I have tried (a) and found it OK. For (b) it is NOT stable for Rpi3B+, though many guys claim it works, but NO ONE gave any details, not even raspbian version and date. I wasted perhaps 20 hours and finally.

GPIO boot mode is only available on the Raspberry Pi 3A+, 3B, 3B+, Compute Module 3 and 3+. The Raspberry Pi can be configured to allow the boot mode to be selected at power on using hardware attached to the GPIO connector: this is GPIO boot mode. This is done by setting bits in the OTP memory of the SoC.
