Logic

This program implements six digital logic operations, with each operation's result sent to a different output jack.

ain: the first boolean input; any signal above 0.8V is treated as ON, anything below that is OFF. (Note: this is the same voltage threshold used on the digital input.)
din: the second boolean input
cv1: ain AND din
cv2: ain OR din
cv3: ain XOR din
cv4: ain NAND din
cv5: ain NOR din
cv6: ain XNOR din

The outputs are as follows:

Output No.	Operation
Out 1	AND
Out 2	OR
Out 3	XOR
Out 4	NAND
Out 5	NOR
Out 6	XNOR

The following table shows the value for each operation for every input combination:

Din	Ain	AND	OR	XOR	NAND	NOR	XNOR
0	0	0	0	0	1	1	1
0	1	0	1	1	1	0	0
1	0	0	1	1	1	0	0
1	1	1	1	0	0	0	1

The screen will go to sleep after 20 minutes of inactivity. Pressing either button will wake the screen up.

The knobs are not used in this program.
