spilite
A lite wrapper for spidev.
Overview
Spilite is a wrapper for spidev. It adds
- Entry and exit behaviour so that a SPI device can be treated as a file handle
- Additional types to support different software controlled chip select schemes
- single pin (active high or low)
- hardware address decoder (e.g. 74HC138)
For pin behaviour, gpiozero types are used. This approach assumes that the hardware control of the chip select is not used (i.e. not using the hardware flow control with the micro's own SPI controller).
Example
import spilite.spi as spi
from spilite.cs.pins import ChipSelectPin
# setup chip select pin
cs_pin = ChipSelectPin(21)
cs_pin.unselect()
# setup the SPI bus device (speed and cpol)
dev = spi.Port(cs=cs_pin, max_speed_hz=1000000, mode=0b11)
# ...
# send/receive two bytes
buffer = [0xff, 0xab]
with dev as bus:
bus.xfer2(buffer)
