hi ppl!

anybody noe how to display character on VGA monitor when i type a character in the hyperterminal of another pc which link to the FPGA Spartan 3 board?

thz thz! =)
 

Hyperterminal controlled character generator on VGA monitor

Here's a simple very basic VGA text display that I created for the Xilinx/Digilent Spartan-3 Starter Kit. It uses a PS/2 keyboard input module that I found on OpenCores. Maybe you could replace the PS/2 module with an RS-232 UART module.

thz!

but do u hve any c code for it?
 

No C code needed. Maybe I misunderstood your project description?

My small example design (written in Verilog) runs in the FPGA on the Spartan-3 board. You plug a keyboard and VGA monitor into the board. The FPGA receives keypresses from the keyboard, and displays the characters on the monitor.
 
i've attached the flow of my project. hopefully it can help u understand better. =)
 
Ok, your project diagram matches my original understanding, except how does a VGA monitor connect to two places at once?

I don't see any place for using C code.

You would of course need to replace the PS/2 keyboard module in my example project with a UART module, as I mentioned earlier.
 

Cause one monitor is to open the hyperterminal and another is to display the keyboard character. The monitor that use to display the character is connected to the vga port of the spartan-3 board.

Im using C code for this project because im using MicroBlaze.
 

No MicroBlaze in my example project. Is it a requirement for your project?
 

yep. coz my project is to look more into MicroBlaze and discover how effective is it.
 

does anyone noe how to check and delcare the vga timing for the code then?coz i need a time input to know when to display a pixel on the VGA screen.
