Linux sysfs gpio access
This library provides gpio access via the standard linux sysfs interface
It is intended to mimick RPIO as much as possible
for all features, while also supporting additional (and better named) functionality
to the same methods.
Supported Features
- get pin values with
read(pin)
or input(pin)
- set pin values with
write(pin, value)
, set(pin, value)
or output(pin, value)
- get the pin mode with
mode(pin)
- set the pin mode with
setup(pin, mode)
mode
can currently equal gpio.IN
or gpio.OUT
- create a
GPIOPin
class directly to write
and read
a pin
Examples
RPi.GPIO Drop-in
Good for up to 130KHz pin toggle on a Pi 400.
import time
import gpio as GPIO
GPIO.setup(14, GPIO.OUT)
while True:
GPIO.output(14, GPIO.HIGH)
time.sleep(1.0)
GPIO.output(14, GPIO.LOW)
time.sleep(1.0)
Use GPIOPin directly
Good for up to 160KHz pin toggle on a Pi 400.
This gives you a class instance you can manipulate directly, eliminating the lookup:
import gpio
pin = gpio.GPIOPin(14, gpio.OUT)
while True:
pin.write(14, GPIO.HIGH)
time.sleep(1.0)
pin.write(14, GPIO.LOW)
time.sleep(1.0)
