Generate Shapes using Verilog

[hubakboy]

Is its possible to display shapes (specifically a square or a rectangle) on a LCD screen connected through a FPGA board by using Verilog HDL??

 

[TrickyDicky]

Yes. It is possible.

 

[hubakboy]

Can you show me some source codes or references in generating these shapes?? I would really appreciate it.

hubakboy,



What you are requesting refers to a specific implementation of a code program using some amount of libraries.
Better you start with a simplest design requirement ( e.g. "How to interface graphic LCD with Verilog" ) and gradually develop desired routine. Taking a look on forum previous questions related to this subject, could find this one which apparently could answer your need.

A Verilog code to display a simple rectangle through the LCD screen. Still too vague?

In a sense it is still vague, as it largely depends of the specific type of LCD to which you refer.

Are you referring to a monochrome GLCD, TFT LCD, etc.

In either case as Andre has pointed out, the first step would be to define the specific LCD and develop an interface to drive that device.

Once this task has been accomplished, developing methods of generating rudimentary shapes can be undertaken.

Thank you for your replies! But I think I made an error in typing.. What I meant is that I aim to display the square or rectangle to a LCD monitor connected through the FPGA, not the LCD screen that lies within the board. Will I still go with interfacing LCD with Verilog as what andre_teprom suggested or will this require another way to implement this? Appreciate the help once again.

Sounds like you want to design a graphic display controller. You should decide for a display interface, e.g. VGA, DVI and an image resolution.

Example designs can be found on the internet.
