RockPI S gpio python libary

Hey there

Is there a python libary available for the RockPI S gpio´s ?

Greetings

Yes, libmraa python bindings.

Install:
https://wiki.radxa.com/RockpiS/dev/libmraa

API:
http://iotdk.intel.com/docs/master/mraa/python/

My RockPiS arrived this week .

I use the Armbian Distro and installed libmraa like the description :

  export DISTRO=buster-testing      # for Buster

echo “deb http://apt.radxa.com/$DISTRO/ ${DISTRO%-*} main” | sudo tee -a /etc/apt/sources.list.d/apt-radxa-com.list
Get the pub key
wget -O - apt.radxa.com/buster-testing/public.key | sudo apt-key add -
Install essential packages:
sudo apt-get update
sudo apt-get install -y rockchip-overlay rockpis-dtbo libmraa-rockpis

but “import mraa” does not work with Python

What i have do too else?

greetings

Hello I tired it again on:

import mraa
Traceback (most recent call last):

ModuleNotFoundError: No module named ‘mraa’

But stil the same "No module named ‘mraa’.

Why is this Module missing?

We updated kernel today. Try if its working now: apt update & apt upgrade

i tried with a fresh img:

apt update
apt install wget
export DISTRO=bionic-testing
echo “deb http://apt.radxa.com/$DISTRO/ ${DISTRO%-*} main” | sudo tee -a /etc/apt/sources.list.d/apt-radxa-com.list
wget -O - apt.radxa.com/buster-testing/public.key | sudo apt-key add -
apt-get update
apt-get install -y rockchip-overlay rockpis-dtbo libmraa-rockpis
apt upgrade -y
apt dist-upgrade -y

same result module not found

Can you provide armbianmonitor -u?

The librmaa-rockpis does not contain python bindings - it only contains examples.
That’s why the module cannot be found :frowning:

I’m so sorry, pumuckll.Due to our PIS compiling libmraa library, we did not choose to compile Python library. You can download our libmraa library and compile it yourself.
The steps to compile are:

1.Some dependency libraries need to be installed before Compilation,
sudo apt-get install git build-essential swig3.0 python-dev python3-dev nodejs-dev cmake libjson-c-dev

2.cd libmraa
Open cmakelists.txt file
Find the following content, modify the configuration to choose to compile the support of different libraries

option (BUILDDOC “Build all doc.” OFF)
option (BUILDSWIG “Build swig modules.” ON)
option (BUILDSWIGPYTHON “Build swig python modules.” ON)
option (BUILDSWIGNODE “Build swig node modules.” ON)
option (BUILDSWIGJAVA “Build Java API.” OFF)
option (USBPLAT “Detection USB platform.” OFF)
option (FIRMATA “Add Firmata support to mraa.” OFF)
option (ONEWIRE “Add Onewire support to mraa.” ON)
option (JSONPLAT “Add Platform loading via a json file.” ON)
option (IMRAA “Add Imraa support to mraa.” OFF)
option (FTDI4222 “Build with FTDI FT4222 subplatform support.” OFF)
option (ENABLEEXAMPLES “Disable building of examples” ON)
option (INSTALLTOOLS “Install all tools” ON)
option (BUILDTESTS “Override the addition of tests” ON)
option (USEPYTHON3TESTS “Force tests to run with python3” OFF)

3.mkdir build
cd build
cmake …
make
sudo make install

Or we can recompile the python support and give you a new version

thanks for the information

I will try to compile it,but I would recommend too include it in future.

Where could i download it?

We have compiled the new libmraa library and are preparing to upload it

cool many thanks

in that case i will wait for it
