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.

Hello

can anybody suggest me how to do it with an example code...

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.
