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:

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.
