SPI Pins

Enabling The SPI Port

Via the desktop GUI

In the desktop GUI select the Start button > Preferences > Raspberry Pi Configuration

Select the interfaces tab and then select the relevant option.

Via the config file

Use the sudo raspi-config

config tool:

sudo raspi-config

Select ‘Interface Options’ and then select the relevant option.

Test the SPI Port

Test the SPI port is working by typing:


ls /dev/spidev*

You should see the following:


/dev/spidev0.0  /dev/spidev0.1

There are 2 spidev devices shown.  The first number refers to the SPI peripheral which in both cases is 0 (the RPi only has 1 SPI port), the second number represents the chip select pins CS0 and CS1 .

    What’s the reason for those services to be disabled? As far as I see I can still use the SPI-GPIO pins any way, or am I wrong?

      They are just standard IO pins until their SPI function is enabled.
