tungsteno74 / npi.gpio Goto Github PK

You are the only person I have found that took the time to make this work with Python3.
Unfortunatly, the NanoPi Duo2 was not included.
If you don't have the time to add it, that is ok, but would you be able to tell me then what files I would need to change and what to add to make that happen.

Sorry to bother you, but thank you for the time.

Hi there,
I have a NanoPi M2, I installed OS is DietPi. I cannot install "NPi.GPIO". I read that "NPi.GPIO" can only be installed on armbian? Is there a way to install it anyway?

pi@NanoPi-Duo2:~$ sudo python3 npi_gpio_1.py Traceback (most recent call last):
File "npi_gpio.py", line 1, in
import NPi.GPIO as GPIO
File "/usr/local/lib/python3.5/dist-packages/NPi.GPIO-0.5.8.6-py3.5-linux-armv7l.egg/NPi/GPIO/init.py", line 1, in
from NPi._GPIO import *
RuntimeError: Is not NanoPi based board.

how to fix?

• change cpuinfo implementation and remove deprecated revision attribute.

This works, but the workaround is kinda sketchy.

The workaround i am using is dropping the /etc/armbian-release file from armbian onto DietPi.
I think this is not really a good solution.

The resource footprint of DietPi is way less than armbian.

Hi there,

If I simply read the input, it returns correct pin status. If I implement add_event_detect, GPIO.input always return the same value no matter in the event callback or other place in the code. Meanwhile, I also check /sys/class/gpio/ and found that the gpio value is correct. My system is NanoPi Neo Core with official ROM released at 2021/04/25. I test my test code on Raspberry Pi 3B. There is no problem at all.
`
def btnPrint(pin):
time.sleep(0.1)
print("Press1:",GPIO.input(pin))
time.sleep(0.1)
print("Press2:",GPIO.input(pin))

GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)
GPIO.setup(62, GPIO.IN)
GPIO.add_event_detect(62, GPIO.RISING, callback=btnPrint, bouncetime=1000)

while 1:
print("main status 1:",GPIO.input(62))
time.sleep(5)
print("main status 2:",GPIO.input(62))
time.sleep(5)
`

Why there's exlicity no NanoPi NEO Core support?

It presumably is the same as NanoPi NEO & AIR, simply with bare headers

In the NEO Core variant, the ethernet and USB A connectors are replaced with unpopulated headers.

And from FriendlyARM own description:

It has the same form factor as the NanoPi NEO and same pin descriptions.

Thanks!

sudo python setup.py install
is working but without sudo I get missing permissions.
Running it with sudo will work on regular desktop but when I do the same inside snap that I am creating (.py file use NPI.GPIO as GPIO) I get an error
Traceback (most recent call last): File "/snap/mainb/x24/on.py", line 3, in <module> import NPi.GPIO as GPIO ImportError: No module named 'NPi'

And the same when using implementing RPi.GPIO as GPIO
(Can't recreate error, my snapcraft crashing now lol)

I managed to recreate this in RPi.GPIO.NP just with the sudo python setup.py install and not bouth python setup.py install and sudo python setup.py install as they asked.

Please be attention that you need use both python and sudo python to make the RPi.GPIO_NP work well.

In the Installation part
cd /NPi.GPI
need to be changed to
cd NPi.GPI

• add version attribute string to __init__.py as semi-standard way.
• add alternative to access gpio memory by /dev/gpiomem instead of /dev/mem. (but armbian seem to not have gpiomem file)
• move log error showed at wrong time when try to open boards information file (/sys/class/sunxi_info/sys_info /etc/friendlyelec-release /etc/armbian-release).
• add link to NPi.GPIO PYPi module in the readme file.
