Hello Phil,
It works now , connecting directly to the raspberry PI .
But the display between custom pages or settings pages takes about 3 to 5 seconds delay, and sometimes more.
Is-it due to the ram (only 1 gb with raspian ?)
With a computer core I5 8th generation 3,5 Ghz , 8 GB ram , W10 , the display between pages is less than a second.
Is it as fast for the MangoHTS ( 8GB RAM max ). (display between pages less than a second ?)
Best regards -

Hello Phil ,
The file /usr/bin/java is present , but when i try to execute it nothings happens.
ma-init.sh is containing already echo but i don’t know how to add one.
As I said I don’t know how to use linux, just very few commands.The situation has been improved but not at all.
I can start Mango , but it’s blocked with 5% starting
I was unable to have the good echo when usin oracle jre 1.8.0_221
So with the command sudo update-alternatives --config java , I choose an another version than oracle 1.8.0_221 :
Java-8-openjdk-armhf

Now I can have a good echo for java -version
I updated the etc/environment file with the following
JAVA_HOME= »/usr/lib/jvm/java-8-openjdk-armhf/jre/bin/java»Of course there’s a problem to launch the display , because I use VNC viewer but I can see the Mango software starting when typing localhost :8080 in the webbrowser bar.
But why Mango is blocked at 5% when starting ?
Is-it because it’s not a oracle version of java ?
Thanks for your help
Best regards

Hello Phil,
i have many difficulties how to use linux, and i followed your tutorial step by step.
But I encountered the problem with the path.
In your tutorial you said :Add the following to the file
JAVA_HOME=/usr/local/java/jdk1.8.0_131
If you have path settings add at the end of PATH following :/usr/local/java/jdk1.8.0_131/bin”
save /etc/environment (ctrl+x)But the syntax is not given by the tutorial.
So that’s why I’m lookink for help.
With your previous comment I know now that the path is not good . But i still don’t know how to write that path in etc/environment.
I tried to start mango with sudo ./ma.sh start command in the bin directory of mango , but mango doesn’t work
is_it because java JRE is not answering ?
because when I check java -version , I have no answer.When you install JDK, does it install in the same time JRE ?
best regards

Hello,
I followed your tutorial to install mango on raspberry PI.
I’m blocked whith the command prompt :
sudo update-alternatives --install java /usr/bin/java /usr/local/java/jdk1.8.0_221/bin/java
as you can see with the following screenshot :
i don’t know linux , and I found on the web a syntax to declare the path for
:/usr/local/java/jdk1.8.0_221/bin but i don’t know if it’s the good syntax.
Here it’s what I wrote on the /etc/environment file :Is-it correct for the path ?
If yes , have you got any idea of my problem ?
I can obtain JDK as you can see in the following screenshot, but not the java version :

Hello jared,
You said : The gist of it is that ma-selector should be set to a CSS selector,
But I don’t even know how to set the ma-selector to a CSS selector !!
Even with the links you gave me , i unable to understand how does it works with mango . (angular JS attributes)
Even with the examples given in mango software I unable to update the code to realise the simple rotating svg object I want.
Using scripts is possible for me , but only if it’s not complicated.
I suppose i have to learn many things to be able to do a page like that :
So, I prefer to stop my involvement in mango.
Thanks for your help.
Bye

Hello,
The following example is taken from a video of mango website showing how to make an image rotating on itself.
It’s possible for me to make an image rotating on its own position, but not for a svg object.The svg objet (called « rotor » in the script code below) is rotating with an offset of several hundreds of pixels.
I can of course use an image instead of a svg object , but the rotation wil not be exactly at the center of the object, it’s why i think it’s better to do with svg objects .
Have you got any idea why is there an offset when rotating ?
Where is it possible to find a documetation on the differents properties and method of ma-selector object ?
result of the display:
Best regards

Hello,
I wonder why is there a special syntax in the example below with the character ! in the sentence :<div ma-selector="#DAS-OFF rect" ng-style="{'fill': !dasStatus.value ? 'red' : 'white'}"></div>
And not in that sentence :
<div ma-selector="#DAS-ON rect" ng-style="{'fill': dasStatus.value ? 'green' : 'white'}"></div>
I tried to remove it but , the animation does’nt work properly.
Any idea ?
Best regards
