If you followed the series, you are familiar with those Step 1: Enable SPI on the Raspberry Pi In your Pi’s terminal, run sudo raspi-config Go to Advanced Options > SPI Choose “Yes” for both questions then select Finish to exit raspi-config Either reboot your Pi or run this command to load the kernel module sudo modprobe spi-bcm2708 Step 2: Install spidev Spidev is a python module that allows us to interface with the Pi’s SPI bus. The I2C peripheral is not turned on by default. To enable it, do the following. 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 . All code is MIT licensed unless explicitly stated otherwise. Its 40 Pins support the protocols I2C, SPI, and UART. Jan 6, 2013 · While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI Nov 24, 2015 · Using Raspberry Pi SPI in Python Contents Intro Software setup Example Python program Intro We already learnt how to use Raspberry Pi with GPIB interface to communicate with lab instruments. Most SPI examples operate as master to communicate with a slave device. For running the python code in Raspberry Pi official link. By mixing hardware and software chip select handling, you can connect as many devices as you need. These peripheral devices may be either sensors or actuators. Sep 15, 2025 · Project description Python Spidev This project contains a python module for interfacing with SPI devices from user space via the spidev linux kernel driver. .
