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

Here is the screenshot of java versions available

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

here is the screnshot of the check starting mango

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 :

Best regards

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
