> all you need is an EDK tools chain

I guess I should have bought my development board from xilinx instead
of digilent.  I've been trying to find a trial version of the EDK from
xilinx but I'm not having any luck.  From the posts I've read here, it
doesn't sound like its available.

Are there any xilinx employees in here who could put the trial up for
download?  I'm just doing this for a hobby and can't begin to justify a
$500 program unless I know that it is what I want.  :(  I don't
understand why the same product from digilent doesn't come with any
software...

If you want to simplify your video, take a look at the projects on
fpgaarcade or c-one that use a scan-doubler to convert composite output
to vga. If you connect your resistor dac to gpio on the board rather
than the vga port, you can output both simultaneously.

If you google around you'll find a few samples of ntsc/pal out there.
Most of what I've seen relate to games on FPGA...

if you want telnet, you need an IP stack, so you need an OS... then try
uClinux and you are done !

see http://muranaka.info for the reference design (or xilinx
xapp730.pdf) and follow guidelines. runs perfectly out of the box
see also http://petalogix.com (same design)

all you need is an EDK tools chain

enjoy

I just bought the S3EBOARD from Digilent
(http://www.digilentinc.com/Products/Detail.cfm?Prod=S3EBOARD&Nav1=Products&Nav2=Programmable)
to be my first FPGA board.

For my first project I want to make an ADM3 serial terminal emulator
with telnet over ethernet ability.  It will just be a character based
display with PS/2 keyboard for input and VGA for output, and the serial
port for the terminal in/output.  My plan is to use one of the slide
switches to select VGA or NTSC.  NTSC video would be provided using a
little PCB connected to the VGA connector (just black and white video
from 2 wires).  The switch would just tell the FPGA what timing and
video method to use.

That part is simple.  The other thing I would like to do is use the
ethernet interface to allow external clients to telnet to the serial
terminal.

I have read about using the MicroBlaze core and lwip, so I am reading
about those to try and see if they will help me any.

Any suggestions or hints that would help me with this project?  Any
sample code on 1 bit NTSC (B/W) using two wires and a few resistors?

I think the hard part will be the telnet function.  Hopefully this
board comes with PS/2 and VGA code examples!  Does anyone have this
board know what kind of examples it comes with?
