Description:
python3spi 0.3.1
python3-spi
Python 3.x interface for SPI communications using Linux spidev
This is a fork of https://github.com/tomstokes/python-spi which seems to be abandoned with the python 3 compatibility patch proposed by Tom Egan applied.
Features
Pure Python implementation. No C module to compile.
Supports half-duplex reads and writes as well as full-duplex transfers.
Exposes all available spidev interface options as properties.
Requirements
spidev enabled in the kernel and (if necessary) the device tree.
Write permissions to the /dev/spidevN.N device.
Some distributions have an 'spi' group for this purpose. If available, add this group to the user account and ensure the spidev device is group-writeable.
If no 'spi' group exists, a udev rule can be created to set the permissions of the spidev device.
As a last resort, running the python script as root should allow access to the spidev. Note This is not recommended. Use the 'spi' group or udev rules whenever possible.
Example
import spi
spi = SPI("/dev/spidev1.0")
spi.mode = SPI.MODE_0
spi.bits_per_word = 8
spi.speed = 500000
received = spi.transfer([0x11, 0x22, 0xFF])
spi.write([0x12, 0x34, 0xAB, 0xCD])
received = spi.read(10)
