Duke-Pad

[ric96]

Anyone brave enough to try this : https://wiki.openjdk.java.net/display/OpenJFX/DukePad

Funny, I've thinking to build a tablet with RPi since it has came out. I've bought the same LCD panel with HDMI adapter, and the same battery pack from Amazon they wrote in the part list. I also have camera module. So, except the case, MPU 9150 Gyro/Accel/Mag, and some small accessories, I have everything for it Last night I've started to build the software part of it, today I will finish it.
I've printed the case plan in A3 format, compared the LCD panel to it but the print is smaller So it can't be use without modification) I would order cutting the case from acrylic if I had the plan in proper format.

On your desktop, clone http://hg.openjdk.java.net/openjfx/8/graphics/rt

how am i supposed to do this???

On Ubuntu/debian/Mint

Code: Select all

sudo apt-get install mercurial
man hg

On Windows :

I am very interested in this.

Apologies if it's a basic question but - will the Duke-Pad run 'typical' Raspberry Pi things - in my case:

- Terminal and GNU/Debian tools (e.g. gcc, bash, apt);
- Web browser;
- Some kind of office software (e.g. LibreOffice)?

I don't care about X11 specifically - if the GUI is achieved by other means this is fine.

Thank you,

Daniel Barker

I guess fullscreen JavaFX and X11 are exclusive on the Pi : You can't have both at the same time , but you
should be able to shutdown the one to launch the other , without rebooting the OS (similiar to XBMC on Raspbian) .

a little bit help on

If you are using IntelliJ IDEA, locate under rt/apps/experimental the DukePad project. Open it and build. It should build, auto-downloading dependencies from maven central. Alternatively, you can try using the gradle build file. To do so, cd into rt/apps/experimental/DukePad. Execute:


me@my-computer:$ gradle artifacts

cant get this to work
using ubuntu 13.04

[ghans]

http://www.gradle.org/downloads

Gradle is in the repos for 12.04 LTS though.

This could help? : http://www.raspberrypi.org/archives/4920

or should i do this? : https://wiki.openjdk.java.net/display/O ... ng+OpenJFX

[ric96]

i think you can give it a try on the pi

have already tried , same problem

Has anyone tried this? : jdk-8-ea-b109-linux-arm-vfp-hflt-25_sep_2013.tar.gz

Has anyone tried this? : jdk-8-ea-b109-linux-arm-vfp-hflt-25_sep_2013.tar.gz

just another weekly build
will and probably does have the same result!

[sirkope]

And then? We should gave it up?

[Markamc]

I've managed to build in virtualbox - ubuntu13.04 using itellijidea 12.
After adding OSGI/maven plugins inside Intellijidea and changing project structure settings etc, I can build/run with no errors in Ubuntu but not yet Rpi, still working on it. Will post later with update.

Cheers,
mark

[sirkope]

Any news?

[idorel77]

Any news? heeeeellllp!

[Markamc]

Sorry, not had too much time and reached a standstill,. Can compile and run in windows/linux (virtualbox), but can't run released or on pi, so stumped for the moment.

that's y i mentioned BRAVE,, it needs a lot of debugging!
