Interfacing the Spartan 3 Starter Board to the Atmel STK500/501 Starter Kit

This is going to be, hopefully, a very fun project. It is
going to involve writing a lot of verilog code to run on a Spartan 3
FPGA, as well as C code for running on an ATmega2561 microcontroller.
The goal is to interface the FPGA to a CS4385 8 channel DAC to
make a very nice 256 channel digital synthesizer. There are also
going to be interfaces to a VGA display to display status and debug
info. This should be a big help if I can get it to work. I
might also make a mouse interface.
I have little pieces of it partly complete. Nothing, so far, is done.
This board is used to interface between the Spartan 3 Starter Board to the Atmel SDK500/501 board set.
VGA Display IP
This is the verilog code for a VGA interface adaptor. This is almost ready to be tested.
Windows Font Editor Program
This is a program for creating character fonts. It will save files as either a binary file, coe file, or C/C++ data file.
This is the verilog code for an I2S interface and a digital synthesizer.
This is the verilog code for a MIDI port....well, why not.
This is the firmware for running in an AT mega for controlling all of this. Uses a Real Time OS to boot...
Windows Host Program
This is for testing and controlling the hardware.
