Honored ContributorConnecting a Graphics LCD to Max10
I am looking to wire up a small 1/4 VGA LCD to my DECA board, I'd like to show some simple graphics (labels, maybe some text boxes, indicators, etc)...No animation or anything like that. I do not want to use any HDMI (such as a computer monitor), but an actual wired hookup. Ae there any straightforward guides or examples for such an endeavor?

Altera_ForumHi, fast solution is to hook up a cape for BB, then you assign pin and adapt university program or you can write your own display code.

Seen after reading again, quarter VGA seems as smaller LCD, this way different interfaces are present, LCD parallel or computer based both parallel or serial, which device you are thinking about?

Thanks, but the idea is to use the power of the MAX10 to run the LCD display. I am under the impression that it is powerful enough do so, especially for a 5 or 6 inch touch display...with the FPGA configured as a LCD display controller & graphics processor. The LCD would have about 20-24 RGB lines & of course various clock & sync signals.
Just want a few touch control buttons and maybe a few sliders to interact with some numeric text boxes...(no animations or any "smart phone" scrolling features)....to feed values into the FPGA and display processing results from the FPGA. Are there any tutorials/examples to take a look at, or to see what tools for graphics Altera has? I'd think setting up a small control panel would be pretty popular anywhere the max10 is used in an embedded situation--but I am having trouble finding any useful information, or even examples of this. - Altera_Forum
HI, if full Linux with HD support over HDMI can be run on this board, image processing merging images and videostream from camera why it cannot support it on a smaller TFT with reduced stream speed?
I use TFT on this board, I simply plugged on the 4D model I sent you the link, it work very fine with all my IP cores and NIOS. Can someone can port TFT Linux driver too but this is a time consuming task and I cannot do myself for now. About simple images check what you need and scale IP cores to fit your need. Nothing can be said, you can use a blitter to display block from a flash or compute someting from embedded processor then display dot by dot. Regards - Altera_Forum
documentation from Terasic
http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&no=944&partno=4 you can find some other examples on Arrow site. - Altera_Forum--- Quote Start --- documentation from Terasic http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&no=944&partno=4 you can find some other examples on Arrow site. --- Quote End --- I don't see anything on the Arrow site, other than to order parts---where are you looking (link)? Do you have an example of setting up a simple control panel? A few buttons and siders perhaps? The Terasic manual doesn't mention how to do this at all, or seem to create any kind of display graphics. Where does Altera keep its graphics control examples?

Is there a quick way to hook up a 4.3" display and show some simple messages, even without touch control..looking for some working examples

Hi, Browsing arrow site result empty, I was remembering file of workshop was there but time help forget details.
Here are general board reference: http://www.alterawiki.com/wiki/deca - Altera_Forum
From Rocketboard (Deca manufacturer or project involved) reference design
https://rocketboards.org/foswiki/view/projects/graphicsonalteramax10arrowterasicdecaboard - Altera_Forum
and there is reference design workshop I attended at Arrow.
http://www.alterawiki.com/wiki/deca Fastest way as I said is to hook up 4DSystems cape, I don't know if something ready exist for DECA. My design drive that display but sorry I canot publish due it is not free, I wrote in it's entirety after trying university program. I can post interface module with pin names and script to assign 4DSystem display cape. regards
