💡 Hint

Common Mistakes

Using 'remove' instead of 'install' will uninstall the package.

Using 'update' or 'upgrade' does not install new packages.

The command sudo apt-get install i2c-tools installs the I2C tools package needed to work with I2C devices.

💡 Hint

Common Mistakes

Using '--enable-i2c' directly is not a valid raspi-config option.

Using 'interactive' is the default mode, not a command option.

The raspi-config nonint option allows non-interactive configuration, useful for scripting.

💡 Hint

Common Mistakes

Using 'disable' will turn off the I2C interface.

Using 'set' or 'get' are not valid for this command.

The correct command to enable I2C is sudo raspi-config enable i2c.

4fill in blank

hard

Fill both blanks to add I2C modules to the Raspberry Pi boot configuration.

Raspberry Pi

echo '[1]' | sudo tee -a /etc/modules
sudo modprobe [2]

Drag options to blanks, or click blank then click option'

Ai2c-dev

Bspi-dev

Di2c

Attempts:

💡 Hint

Common Mistakes

Using 'spi-dev' instead of 'i2c-dev' is wrong for I2C.

Using 'i2c' alone is not a valid module name.

The i2c-dev module is added to /etc/modules to load at boot, and i2c-bcm2708 is loaded immediately with modprobe.

Fill all three blanks to check connected I2C devices on Raspberry Pi.

Raspberry Pi

sudo [1] -y [2]

Drag options to blanks, or click blank then click option'

Ai2cdetect

C0

Di2cdump

💡 Hint

Common Mistakes

Using 'i2cdump' instead of 'i2cdetect' will not scan devices.

Using bus 0 instead of 1 may not detect devices on newer models.

The command sudo i2cdetect -y 1 scans the I2C bus 1 for connected devices. Bus 0 is older and less common.
