The Iв¬ controller on the Raspberry Pi 3B, 3B+ and Zero W has its clock linked to the VPU core so as the VPU frequency changes depending on processor load so does the clock rate of the Iв¬ bus. Notes for the Raspberry Pi 3B, 3B+ and Zero W Save your changes, exit the nano editor and reboot Open the file with nano using the command:ДЄdd the following text to the bottom of the file The number is the frequency of the Iв¬ bus in hertz: You can set the bus speed by editing /boot/config.txt. The Iв¬ bus supports several bus speeds, typically 100KHz, 400KHz, 1MHz, 3.4MHz and 5.0MHz. I2cdetect will display a grid of numbers with the addresses of any Iв¬ devices shown within the grid. You can test if i2ctools is working by listing all of the Iв¬ devices connected to your Raspberry Pi.

Sudo apt-get install python3-smbus python3-dev i2c-tools With the Bullseye release of Raspberry Pi OS the Python 2.7 package has been removed so you will need to run the following commands.

Sudo apt-get install python-smbus python3-smbus python-dev python3-dev i2c-tools If you are using the Buster release or earlier you can use the following commands. If you are using the Lite version ofВ Raspberry Pi OS you may need to install the i2ctools package as well as several python libraries. Installing I2C Tools and Python Libraries

When your Raspberry Pi has rebooted you will now have Iв¬ and SMBus Python 2 or 3 support. Select 3 Interface Options and then P5 I2C.В A prompt will appear asking Would you like the ARM I2C interface to be enabled?, select Yes, exit the utility and reboot your Raspberry Pi. If you are using Raspberry Pi OS Linux 3.18 or later you need to go into the raspberry pi config utility and enable Iв¬. Step 1: Download the latest Raspberry Pi OS linux image and burn to your SD Card following the instructions on Click shutdown at the bottom of the menu and in the dialog box that appears click reboot. Click on the Enable button next to Iв¬ and then click the OK button.Д«efore you can use the Iв¬ bus you will need to reboot your Raspberry Pi so click again on the start menu icon. Click on the Interfaces tab and find the Iв¬ option. Click the preferences icon and select Raspberry Pi Configuration.ДЄfter a few seconds, the Raspberry Pi Configuration program will open. Once booted click on the start menu in the top left corner. Watch the video or follow the steps below to enable the Iв¬ port from within the Raspberry Pi OS Desktop environment.Д«egin by turning on your Raspberry Pi and allow Linux to boot to the desktop.

The Iв¬ port on the Raspberry Pi uses the pins GPIO2 (SDA) and GPIO3 (SCL) as shown below.Д®nabling Iв¬ using the Raspberry Pi OS Desktop
