  • parameters
    • edge : interrupt edge (Gpio.NONE, Gpio.RISING, Gpio.FALLING, Gpio.BOTH)

• Gpio.input()

  • returns
    • input value

• Gpio.output(value)

  • parameters
    • value : output value

• Gpio.setisr(isr)

  • parameters
    • isr : interrupt service routines's callback function

example

input interrupt

from time import sleep
from g4l import Gpio

print('g4l example')
gpio = Gpio(100)
gpio.direction(Gpio.IN)
gpio.edge(Gpio.RISING)
gpio.setisr(lambda:print('gpio isr'))
    
print('loop start - toggle gpio')
cnt = 0
while True:
    print(f'loop {cnt}')
    cnt += 1
    sleep(5)
