Hello,
I've been woking on getting the LCD on my Spartan 3E Starter Kit board
to work without the use of PicoBlaze. I've managed to get an init
sequence, but I cannot get a write or read working. I get lots of
warnings.
the files are here in the second state machine is where the warnings
come up:
http://laserbeak43.webs.com/Verilog/init.v
http://laserbeak43.webs.com/Verilog/consts.ucf
here is the list of warnings:
=======================================================================
