What is SPIdev Raspberry Pi?

Serial Peripheral Interface (SPI) is a full-duplex serial protocol for communicating with high-speed peripherals. The SPI Controller on Raspberry Pi™ hardware can drive two SPI peripheral devices.

What is SPIdev?

The SPI bus (or Serial Peripheral Interface bus) is a synchronous serial data link originally created by motorola. There is a way of using the spi kernel driver to work as a device in the userspace. It’s called SPIdev.

What is Spidev in Python?

This project contains a python module for interfacing with SPI devices from user space via the spidev linux kernel driver. This is a modified version of the code originally found here. All code is GPLv2 licensed unless explicitly stated otherwise.

What is remote GPIO in Raspberry Pi?

One of the pin libraries supported, pigpio, provides the ability to control GPIO pins remotely over the network, which means you can use GPIO Zero to control devices connected to a Raspberry Pi on the network. You can do this from another Raspberry Pi, or even from a PC.

What does SPI xfer do?

The spi. xfer function does the transmission and receiving of the data, and then the next line does the conversion.

How do I enable SPI on Raspberry Pi?

Does Raspberry Pi have I2C?

Inter-Integrated Circuit (I2C) is a protocol for communicating with low-speed peripherals. Depending on the model and revision of your board, Raspberry Pi™ hardware has one or two I2C buses. Each bus has an I2C Central connected to two bidirectional lines, serial data line (SDA), and serial clock (SCL).
