Creating GUI

Hello

Thanks for your reply.

The main problem is with my board. I am using DE1 board.

Please suggest how to change my SOPC so that i can display my GUI on the monitor.

Whatever the link u have send is for Stratix board.

You can have a look at the following demo.

http://www.altera.com/support/refdesigns/sys-sol/computing/ref-niosii-vga.html

though, its for different board i suppose. But the software will give you idea about the simple graphics libraries.

I think, you will have to combine the understanding of reference design for DE1 board and the one in above mentioned link.

Regards

Hi,

If you want to display just GUI on the VGA monitor, you will need a frame buffer allocated for VGA frame in memory. Use Nios to write your GUI in that allocated buffer memory.

You will need SGDMA to transfer the frame from memory to the VGA controller. Run this SGDMA in continuous transfer mode.

hope this would help.
