SUMMARY:
This is a color based encryption/decryption program that sends its data
over UART
INSTRUCTIONS:
Hardware:
Nexys 2 FPGA (2)
Serial Cable (1)
Serial Null Modem (1)
Computer (1)
ps2 Keyboard (1)
Vga monitor & cable (2)
Running:
Load rx onto one board, and plug in the ps2 keyboard.
Load tx onto the other board.
Connect the two boards with the null modem and the serial cable.
You can now send messages between the boards.
As long as background color is the same on the two screens, the
message will appear on both.
When the colors mismatch, gibberish will print.
Move the switches to select colors.
FUTURE WORK:
Remove the jitter on the tx. After hours of work, we can't get the
display quite right.
Load an image into the memory, and read it pixel by pixel using one
pixel for one character. This way both sides need an identical
picture to send and recieve. Use switch 8 to indicate this option.
Write it so each board does both rx and tx. Select by button?
PROJECT BUILD OPTIONS:
Normal synthsis
PROJECT SIZE:
RX:
188 Slices used (2%)
approx 3366 lines of code (some identical to tx)
TX:
373 Slices used (8%)
approx 4006 lines of code (some identical to rx)
This is larger because of the ps2 code for the keyboard.
