Parallella Community

Hi everyone again.

The LCD board+Android was tested together this week and yes, you guessed it, it works - see it smile as Parallella gets Android support!

As for the IPcore used I did write it before - it is our own IPcore which will be opensourced.
The LCD we used has I2C touchscreen signals in the pinout. We will share the LCD model we used with everything else.

We will proceed to cleanup the SW and board files we have now for publishing, since we know the whole stack works. Stay tuned!

Best regards,
Michael

Michael, That is awesome!! Well done!
Andreas

I would like to congratulate you Michael and your team for designing a ipcore gpu and lcd touchscreen daughterboard for parallella. I read that you will publish your work as it is planned to be open source. Where and when could I find the work on ipcore gpu and android port, that your team ported.

Thanks for great work.

Really nice work!

BTW, will this GPU IP core have some HW acceleration for Android graphics (OpenGL ES support)?

Hi everyone,

This is taking a tad longer than expected since we are quite swamped with projects, but we made an important milestone - all the files necessary to reproduce the board are now released on GitHub under GPL, so we can officially say the board is open hardware!

The files can be grabbed from here:

As for the GPU, this is work in progress, don't worry, it will be there when it is ready. I will unveil more details when I can.

Great evolutions since my last visit

Not being a hw aficionado. Are there limitations on the lcd this board + gpu would be able to steer ? If i'd want to build a tablet-ish 17" thing would it be doable ?

Hi everyone,

As promised we're posting more links to the rest of the stuff we did for the board (consider it a late Christmas present):

The ipcore + Xilinx PS project is realesed on the BSD 3-clause license; Linux stuff is of course GPL.

There is a Linux driver for the ipcore, LCD timings are configurable inside the devicetree.

As for the question above about 17", well the size does not really matter, what does is the resolution - if it is higher, everything will be slower.
Linux should work without a problem, but software OpenGL/EGL would be too much (note that this ipcore is not a 3D accelerator, but a simple framebuffer LCD driver).
