Hello

I've run led.py test and ended up with:

Traceback (most recent call last):
  File "./led.py", line 2, in <module>
    import RPi.GPIO as GPIO
  File "/usr/local/lib/python3.5/dist-packages/RPi/GPIO/__init__.py", line 23, in <module>
    from RPi._GPIO import *
RuntimeError: This module can only be run on a Raspberry Pi!

I guess that I should not install rpi.gpi via pip3 but I'm trying to switch my working project from rPi to NanoPi and I did it out of habit. When I removed rpi.gpio via pip3 i got that the rpi.gpio module was not found.

Code: Select all

Traceback (most recent call last):
  File "./led.py", line 2, in <module>
    import RPi.GPIO as GPIO
ImportError: No module named 'RPi'

I'm using latest legacy ubuntu image so according to friendlyelec wiki it should include this lib on factory state. So the question is .... how to bring it back? I would like to avoid starting from the scratch as I already spend few hours to replicate databases configure user env - tweaked a lot of stuff and I got stuck with driving gpio pins. Obviously this should be easiest thing to do with this machines .... but it looks like it is not.
Any help would be appreciated.

Anybody using rPi.gpio library?
At the moment I switched to system("gpio write 7 1")
But it is going to make me a lot of problem as my project improve. It is not flexible at all i have chosen FriendlyElec as it was stated that basic support to gpio is compatible with rPi.

It looks you are using the official RPi.GPIO. On NanoPi, you must fallback to RPi.GPIO_NP (_NP for NanoPi). It should be installed on friendlyelec images.

Ads: due to limitations of RPi.GPIO_NP provided as binary form by friendlyelec, we did a reimplementation at https://github.com/auto3000/RPi.GPIO_NP
It can be rebuild for python 2 or python 3 installation.

Could anyone explain me what is pin order in BCM and Board mode? How to compare it to

Code: Select all

gpio readall

results?

Posted: **Tue Jan 16, 2018 8:35 am**

Maybe a reboot was necessary but this is surprising... anyway, I'm not expert in Python runtime. Thanks for your feedback.

I only use BOARD mode. BCM is a "BroadCoM" definition of pins for raspberry pi, this is for backward compatibility between raspberry 1/2/3. Even on raspberry platform, I did not use BCM definition because I found this misleading.

Ok, I set up board and want to light up led on pin GPIO.1

No matter what number I use it won't light up:

Code: Select all

#!/usr/bin/python3
import RPi.GPIO as GPIO
import time

led = 1

GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.setup(led,GPIO.OUT)
print("LED on")
GPIO.output(led,GPIO.HIGH)
time.sleep(1)
print("LED off")
GPIO.output(led,GPIO.LOW)

I tried 12, 1, 6.

when use:

Code: Select all

buzzer_pin      = 1
print("Setting up buzzer pin")
os.system('gpio mode '+str(buzzer_pin)+' out')
os.system('gpio write '+str(buzzer_pin)+' 1')
sleep(0.5)
os.system('gpio write '+str(buzzer_pin)+' 0')

It works like a charm.

Your table extract from wiringpi is helpful.

From the given table, GPIO.1 looks to be the physical pin 12. Could you give a try with BOARD and 12 ?

Code: Select all

#!/usr/bin/python3
import RPi.GPIO as GPIO
import time

led = 12

GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)
GPIO.setup(led,GPIO.OUT)
print("LED on")
GPIO.output(led,GPIO.HIGH)
time.sleep(1)
print("LED off")
GPIO.output(led,GPIO.LOW)

Thank you very much. I really appreciate your help. Like you noticed there were a mistake in my code. I used BCM instead of BOARD. Now the code works ok! I can make progress with my project!

I think that you should include this informations in readme.md inside git repository.

Posted: **Wed Jan 17, 2018 5:48 am**

Do you have any idea how to make this code work without sudo?

Do you have any idea how to make this code work without sudo?

You may have to verify my claim, but I remember RPi.GPIO(_NP) relies on /dev/mem. You may want to put this device file in a group or make it 666 for full read/write access.

This approach is dirty (/dev/mem allow access to any machine resources) and I remember that alternate Raspberry linux kernel introduce a /dev/gpio_mem or something like that. This is exactly the same as /dev/mem but reduce the accessible memory range. There is no such /dev/gpio_mem for AllWinner H3 linux kernel.

I think it would be great if you contribute to the Readme.md with an Howto or Install section or both with your experience. You can cut-paste some messages of this discussion and describe what you did to install on your specific ubuntu/armbian, then create a pull request in GitHub for integration ! The "sudo" limitation is also an important thing.

Posted: **Wed Jan 17, 2018 10:51 am**

I will try tu update readme.md.

Permission to /dev/mem looks like:

Code: Select all

crw-r----- 1 root kmem 1, 1 Jan 11 09:17 /dev/mem

so I allowed kmem to write into device:

Code: Select all

chmod g+w /dev/mem

I moved myself into kmem group with

Code: Select all

sudo usermod -a -G kmem szymon

loged out and logged in again. Id says I'm in kmem group

Code: Select all

15(kmem)

But still I get no permission to access /dev/mem

I also tried:

Code: Select all

 sudo chown root.gpio /dev/mem && sudo chmod g+rw /dev/mem

while default user is in gpio group already
but still no luck.

Code: Select all

Traceback (most recent call last):
  File "./led_board.py", line 9, in <module>
    GPIO.setup(led,GPIO.OUT)
RuntimeError: No access to /dev/mem.  Try running as root!

There have to be some security restriction that prevents writting into memory by anyone.

Anyway after reboot when /dev/mem is recreated permission are reset to default.

Posted: **Wed Jan 17, 2018 12:22 pm**

Right, you did correct. The next investigation is to call the program with "strace" (strace python3 yourprogram.py) and check with call between mmap and open is failing and why (refering to https://github.com/auto3000/RPi.GPIO_NP ... pio.c#L162 code).

Oh I remember the library also access to files in /sys/class/gpio/... you may have a look too these.

I'm in the rush at the moment so I will try to inestigate further this evening or during weekend.

OK your logs are confirming open is returning EPERM (error permission denied).

Code: Select all

open("/dev/gpiomem", O_RDWR|O_SYNC)     = -1 ENOENT (No such file or directory)
open("/dev/mem", O_RDWR|O_SYNC)         = -1 EPERM (Operation not permitted)

After googling this problem, it looks your linux kernel configuration may include CONFIG_STRICT_DEVMEM option. Basically, only root user can access to /dev/mem with this kernel option. The possible "clean" solution are related to kernel modification:
1) disable CONFIG_STRICT_DEVMEM
2) write a driver /dev/gpiomem for AllWinner H3...

Compiling own kernel is not a big problem but it is not worth to shoot with a canon to the bird. Writing a driver is beyond my capabilities.

So I have to play with suid bit.

I've update install.txt please review and merge if you find it usefull. Readme.md is a little confusing it says about Raspberry Pi release.

Posted: **Sun Jan 21, 2018 12:45 pm**

Thanks for the new install.txt, it is clean and this procedure will help many users. Your branch has been merged.

Posted: **Sun Jan 21, 2018 2:42 pm**

In the evening (GMT+2) I will update readme.md to make it clearer about pin mapping. This information are essential for new users.

Any help is appreciated. Thanks for this second contribution.

Posted: **Sun Jan 21, 2018 9:16 pm**

I'm still learnign github.

You don't need to know more things on GitHub, you already know what is necessary when know how to do a branch and create a pull request.

You may want to google git rebase -i, squash commits in git, git push -f but this is really optional.
