💡 Hint

Common Mistakes

Using 'apt-get' instead of 'raspi-config'.

Trying to edit files with 'nano' instead of opening the config tool.

💡 Hint

Common Mistakes

Selecting 'SSH' or 'VNC' which are for remote access.

Choosing 'I2C' which is a different communication protocol.

Selecting 'SPI' in the Interface Options enables the SPI interface on the Raspberry Pi.

Fix the command to reboot the Raspberry Pi after enabling SPI.

Raspberry Pi

sudo [1] reboot

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

Csystemctl

Dshutdown

💡 Hint

Common Mistakes

Using 'start' which is for starting services.

Using 'shutdown' without the correct options.

The command sudo systemctl reboot properly reboots the Raspberry Pi.

Fill both blanks to check if SPI modules are loaded.

Raspberry Pi

lsmod | grep [1] && lsmod | grep [2]

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

Aspi_bcm2835

Bi2c_bcm2835

Cspi_dev

Dusbcore

Attempts:

💡 Hint

Common Mistakes

Checking for I2C modules instead of SPI.

Checking for unrelated modules like 'usbcore'.

The SPI interface uses the spi_bcm2835 and spi_dev modules, so checking for both confirms SPI is enabled.

Fill all three blanks to add SPI to the boot configuration file.

Raspberry Pi

echo '[1]=on' | sudo tee -a /boot/config.txt && sudo [2] && sudo [3]

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

Adtparam=spi

Breboot

Csync

Dsystemctl

Attempts:

💡 Hint

Common Mistakes

Using 'systemctl' instead of 'sync' or 'reboot'.

Forgetting to reboot after changing config.txt.

Adding dtparam=spi=on enables SPI on boot. The sync command ensures changes are saved, and reboot restarts the Pi to apply changes.
