OrangePi Zero 3 wiringpi.wiringPiISR() is Fail #18

Open winitboonkliang opened 7 months ago

winitboonkliang commented 7 months ago

OrangePi Zero 3 2G RAM Model Linux orangepizero3 5.4.125 #1.0.0 SMP Fri Jun 30 11:59:12 CST 2023 aarch64 GNU/Linux

Step install wiringOP-Python with python3.9.2

git clone --recursive https://github.com/orangepi-xunlong/wiringOP-Python -b next cd wiringOP-Python git submodule update --init --remote

python3 generate-bindings.py > bindings.i sudo python3 setup.py install

code python3

import wiringpi PIN_TO_SENSE = 5 def gpio_callback(): print("GPIO_CALLBACK!")

wiringpi.wiringPiSetupGpio() # case 1

wiringpi.wiringPiSetup() # case 2 wiringpi.pinMode(PIN_TO_SENSE, wiringpi.GPIO.INPUT) wiringpi.pullUpDnControl(PIN_TO_SENSE, wiringpi.GPIO.PUD_UP)

wiringpi.wiringPiISR(PIN_TO_SENSE, wiringpi.GPIO.INT_EDGE_BOTH, gpio_callback)

while True: wiringpi.delay(2000)

Result

case 1 used wiringpi.wiringPiSetupGpio()
sudo python3 wiringOP-Python/examples/callback.py Pin mode failed!

case 2 used wiringpi.wiringPiSetup() wiringPiISR: unable to open /sys/class/gpio/gpio70/value: No such file or directory

Problem: gpio_callback does not working

Hi, it seems we both have the same issue. Did you somehow got it fixed?
