Display GUI for TIVA

Dhanush Nair
Expert 1360 points

HI ,

I have my application ready for TIVA .As of now I am using LCD for displaying data.I wish to display data over VGA or HDMI .Is there any interface controller for that. Also then suggest me how to design GUI for the same.

First of all is it plausible with M4 ?? If yes , please suggest.

Regards,

Dhanush

    Hello Dhanush,

    TM4C129 supports LCD Interface and we have tested it on 800x480 Raster Display Panel. However the bandwidth is just sufficient for us to make graphics possible. So if you are expected high end rendering graphics, then it would not be a good choice.

    Also supported on TM4C129 is the LIDD Graphics Panel which is there on the DK-TM4C129 (320x240 resolution graphics display) and performs well due to low bandwidth requirements.

    For HDMI, I am not sure as the HDMI Controller we do not support. If there is a bridge IC from another manufactured for USB to HDMI, then it would need work.

    Regards

    Hello Dhanush,

    Please look at the grlib demo as part of the TIVAWare which uses the EK-TM4C129 evaluation kit.

    For the panel, do you have a VGA Panel? What type: raster or LIDD. To help ease out your development I would suggest using the evaluation kit. The resolution is not VGA but it is a started

     Hi Dhanush, Tiva has not more power to perform good on large screen nor enough ram are available and this is counterproductive than using an OMAP it can suit this use than adding a lot of external part.

     See Beagle Board Black just to compare cost and performance.

     About VGA, did you mean use an external analog connector to a commercial monitor or a vga panel 640x480?

     Again driving this panel is possible but still require external ram connected to EPI and ... Cost performance can be worst again.

     Forever missing too many detail  to help on first/successive too/ request ;)
