Step 1: Enable the SPI port of your Raspberry Pi (If you have enabled it, skip this; if you do not know whether you have done that or not, please continue).

sudo raspi-config

5 Interfacing options

P4 SPI

<YES>

<OK>

<Finish>

Step 2: Check that the i2c modules are loaded and active.

ls /dev/sp*

Then the following codes will appear (the number may be different).

/dev/spidev0.0  /dev/spidev0.1

Step 3: Install Python module SPI-Py.

git clone https://github.com/lthiery/SPI-Py.git

cd SPI-Py

sudo python3 setup.py install

Note: This step is for python users, if you use C language, please skip.
