MorfaLogic

Logic / Clock divider - based on Arduino Nano

A module based around a Arduino Nano.

See: https://janburp.github.io/MorphaLogic

With AND, OR, XOR logic functions, a Flip Flip (Q), a Clock Divider mode, and more.

Logic functions

• Basic logic funcions AND, OR, XOR (using the first inputs on the left side).
• Flip Flop (Q) (first input will SET, second input will RESET).
• NOT input, or MODE button, to inverse all logic outputs (NAND, NOR, NXOR, NQ)
• CLOCK input, when present, all Logic outputs only are HIGH when CLOCK is HIGH
• RESET button to reset Q and CLOCK

Trig button

When the TRIG button is pressed (and released):

• A LOW gate is send to the first (left) output. It will be HIGH when the button is not pressed.
• A short pulse is send to the second output on press & release of the button.
• If the module is in Clock Divider mode, the press & release time will set the Clock Tempe if no signal is present on the CLOCK input.

Modes:

Current mode is set in memory.

Normal mode (mode button is unlit):

• Inputs A & B determines logic outputs (AND, OR, XOR, Q). Where A is set and B is reset for the flipflop (Q).
• If the NOT input is HIGH, all logic outputs are inverted (NAND, NOR, NXOR,NQ)

Inverse mode (mode button is lit):

• Pressing the mode button will inverse all logic outputs (same as when NOT input is HIGH)

Clockdivider mode (mode button is flashing):

• A long press on the mode button will put the module in Clockdivider mode. The mode button will flash.
• The logic outputs will divide the clock (where Q = /2, XOR = /4, OR = /8, AND =/16)
• The clock source is:
  The CLK input
  If no clock is present on the CLK input, a standard 120 BPM clock is used.
  Or, if the trig buttons has been pressed and released, the timing between press and release is used to determine the clock time.

External Trig Mode (trig button flashes):

• A long press of the RESET button toggles between external trig options mode on/off. When on, the trig button flashes.
• When external trig mode is on, the first input can function as an external trig for the trig button.
