HW 9
This homework requires vivado and a keyboard
Task 1: Repeat Textbook.(10 points).
The code uses the functions press, extend, rls, and check to to send
the usb signal. These are needed so if a key is pressed and not
released the code for that key is sent continiously.
The board sits in the RDY state until ontil the start indicator
(ps2data) is pulled low. Then the state is set to recieve where
recieved is written as ps2data. Then the recieved is either written to
data which will displayed on the leds or returned to ready if the
transmission is done.

Task 2: ASCII (90 points).
Figure 2-1: Declarations for reused UART module
Figure 2-2: Case statment to get correct ASCII value
Video 2-1: Demo for serial moniter
There is a minor issue where the previous key is written instead of the current key. I could not figure this out.
Conclusion: Lots of small errors made this take a long time
