odifying the Program

$1.$ The supplied program will load a new pattern if any of the pushbuttons are pressed. You are to modify the program so

that each pushbutton has its own function, as described below. For the sake of the following discussion, we shall label

the rightmost button as button $0($labelled Key $0$ on the circuit board$)$ and the leftmost button as button $3($Key $3).$

Modify the program so that the pattern no longer rotates automatically. Instead, the pattern should rotate to the right

only when button $0$ is pressed, and stop when it is released. Similarly, the pattern should rotate to the left only when

button $1$ is pressed, and stop when it is released. Pressing button $2$ should set the pattern from the switches $($as it did

initially$),$ while pressing button $3$ should reload the original startup pattern stored in memory.

$2.$ Using the getting$\_$started.s and$/$or simple$\_$program.s as reference, you are to write your own program to implement a

pattern matching system which operates as follows.

The system is to compare the $10-$bit value set on the switches to a pattern stored in memory. If the two values match,

then this should be indicated in some manner using the LEDs. $($You can decide how the LEDs indicate the match.$)$

The system should not be comparing continuously, but should only perform the comparison$/$check when

pushbutton $0$ is pressed. The LEDs should not indicate a match before pushbutton $0$ is pressed to check for a match. If

the switch value does not match the pattern stored in memory, nothing should happen.

$3.$ Modify the program in #$2$ above to permit the user to change the stored pattern once they have correctly matched the

current pattern correctly. The user should use one of the pushbuttons to indicate that a new pattern is to be captured

from the switches and used as the new target pattern. This pattern should be stored back into memory to replace the

value originally set in the code. Note that the main monitor tool window has a Memory tab at its bottom, which will

allow you to view the contents of the system memory. Use this to verify that the new pattern is stored correctly
