Hi,

does someone know links to FPGA/CPLD related sites about
VHDL design of VGA controller, hsync, vsync, composite sync in general ?

I would appreciate your help.

Kind regards

Take a look at the projects of the Queensland University
http://www.itee.uq.edu.au/~peters/xsvboard/

There's a lot of information out there: google "vhdl vga controller".

The xilinx spartan 3 starter kit documentation has quite a bit of info on vga
signals and there is a vhdl file you can download here that has a vga character
mapped controller (the microblaze package):

try http://www.fpga.nl/index.html?lancelot.html which is a working VGA
implementation for an Altera Cyclone, have seen it working

look up the datasheet of the video ADC/DAC in question. that should
have more information than you need. it should be easy to write up
state machines that do i2c programming and video sync
generation/reception for the devices u use.
a good place to look for is the eecs150 berkeley class
http://www-inst.eecs.berkeley.edu/~cs150/sp04/

look into the docs section to get the datasheets...you might even find
some verilog code...but i would encourage u to write ur own.

The fpga4fun site also has a couple of PC ish vga,mouse projects too
for the downloading.
