This module defines an object type that allows SPI transactions on hosts running the Linux kernel. The host kernel must have SPI support and SPI device interface support. All of these can be either built-in to the kernel, or loaded from modules.

It used to be supported to define an SPI device using the “spidev” name. For example, as .modalias = “spidev” or compatible = “spidev”. But this is no longer supported by the Linux kernel and instead a real SPI device name as listed in one of the tables must be used.

You can unbind by removing the "spidev" driver module, which will affect all devices using this driver. You can also unbind by having kernel code remove the SPI device, probably by removing the driver for its SPI controller (so its spi_master vanishes).

Enable spidev by adding a compatible spidev. Add a reg property, required for the SPI framework but not meaningful in this case since chip select is not defined and loopback is used. Configure the bus speed for SPI communications by setting the spi-max-frequency property.

Jan 12, 2025 · What is spidev? spidev is a Python library that provides bindings for the Linux SPI device interface. It allows Python programs to communicate with SPI devices by providing methods to configure the SPI bus and transfer data.

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. Full …

In the linux kernel the SPI works only in master mode. There is a way of using the spi kernel driver to work as a device in the userspace. It's called SPIdev. In tools/spi (http://lxr.free-electrons.com/source/tools/spi/) you will find:
