pyGPIO isn't based on RPI.GPIO. It's basically a pyA20 fork for multiple boards. So examples for pyA20 need some changes in naming (e.g. replace 'from pyA20.gpio import gpio' with 'from pyGPIO.gpio import gpio'). 

i have run your python skript with the blinking LED 

it works!

 

where can I get an overview of the commands that change with pyGPIO compared to RPI.GPIO.

As said, untested a short look through the used GPIO-banks didn't show something you should be concerned but you never know.. 

 

i have downloaded the new master GPIO from https://github.com/chwe17/pyGPIO

You need to add a proper mapping.h according to the schematics of your board to get a chance that it works.

 

Here's the template:

https://github.com/chwe17/pyGPIO/blob/master/pyGPIO/gpio/mapping/template40.h

 

and SUNXI_GPX(Z) must be filled in. Replace XZ with the pin which is wired out on this position (e.g. PA10, PG11 etc.). X is the letter, Z the number of this pin. I don't add new SoCs as long as I don't have the board and nobody tests it.. Cause supporting such boards is a nightmare...  So if you write a proper mapping.h, I may add your board to the supported ones, you then have to test if it works properly and if it does, your board gets support by pyGPIO.

 

Banana Pi has a 40-pin GPIO header that matches that of the Model B+ Raspberry Pi. Following is the Banana Pi GPIO Pinout:

https://bananapi.gitbooks.io/bpi-m2/content/en/bpi-m2_gpio_pin_define.html

 

here is my newly created mapping.h for Banana Pi M2

If still not working, maybe your out of luck ... (Better having a more supported board ...)

If you are using Raspbian, all you need to do to install the latest release is:
$ sudo apt-get update
$ sudo apt-get install python-rpi.gpio python3-rpi.gpio

------------

If you are not using Raspbian, it is recommended that you install this module using pip:
$  sudo pip install RPi.GPIO

------------

If you want to build your own version from this downloaded copy, make
sure that you have the Python development source installed first!

On Raspbian:
$ sudo apt-get install python-dev python3-dev

To install the module:

$ sudo python setup.py install
  or
$ sudo python3 setup.py install

that is the install text - I do not have a raspbian

sudo pip install RPi.GPIO is not working

what am I doing wrong?

[BPI M2 how gpio programming]

i used GPIO.setmode(GPIO.BCM)

 

I tried it with WiringPi installed also from lemaker banana pi (not pro)

helmut@bananapim2:/$ sudo gpio -g write 4 1
helmut@bananapim2:/$ sudo gpio -g read 4
0

or:

helmut@bananapim2:/$ sudo gpio write 7 1
helmut@bananapim2:/$ sudo gpio read 7
0
with      helmut@bananapim2:/$ sudo gpio readall    also all pins low 

 

LeMaker Banana Pi support platform with Allwinner A20.

bpi M2 has an platform with Allwinner A31s. can it be that?

or do I have to take the version with banana  pi pro?

 

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setup(22, GPIO.OUT)
GPIO.output(22, GPIO.HIGH)
#GPIO.cleanup()
it is the same  .. no gpio is set

Did you succeeded doing "sudo python" ?

Now I started Python with sudo in the terminal and entered the commands one by one.

now there is no error anymore

but the GPIO is still not set

No needs to uninstall, the Lemaker one will overwrite the previous ...

Now i have install RPI-GPIO from Lemarker 

i used the version bananapi (not bananapipro)

by import no answer

by GPIO.setup(23, GPIO.OUT) i become an errorcode

is my syntax right?

GPIO not set 

 

the GPIO is now properly installed?
or do I have a wrong syntax?

Is there a difference in syntax between GPIO.RPI and GPIO.RPI_BP?

where can i find a table with the syntax

 

how can i test this?

where is my mistake?

 

Thanks for your help

 

new attempt with the pythonshell

why do I have to do this as root?
can I change the rights to the path?

Where did you took this python library ?

If you took it from Raspberry sites, it won't work ...

Maybe this one will, but I'm not sure since I don't own BPI M2 :

http://wiki.lemaker.org/BananaPro/Pi:GPIO_library

 

It is true ... my libary is from Raspberry site and do not work

how uninstall this wrong libary?

than i will test the GPIO libary from Lemaker

hello, im use ARMbian on bpi m2 and will programming the gpio with python.

i have tested with this little script, but i become a runtimeerror.

i can not use the RPI.GPO. What can i used to programming GPO with Python under bpi m2?
