MC2999 is a Craftbook IC that cycles through three outputs, activating one output at a time whenever it receives an input trigger.

Details

• Second Line
  • [MC2999]
• Third Line
  • (StartingPin) optional; defaults to 1.
    • Specifies which output is activated first.
    • Accepts 1, 2 or 3.
• Fourth Line
  • (Mode) optional.
    • Supports the standard Reverse mode, which makes the IC cycle through its outputs in the opposite direction.
    • Only takes "Reverse" as a valid value.

Whenever the IC receives an input trigger, it first turns all outputs off, then activates the output corresponding to its current position. It subsequently advances to the next position.

The outputs are activated in the following order in the default mode:

1. Position 1
2. Position 2
3. Position 3
4. Position 1, repeating the cycle.

In Reverse mode, the order is reversed:

1. Position 1
2. Position 3
3. Position 2
4. Position 1, repeating the cycle.

The IC saves its current position to the third line when unloaded, allowing its cycle position to persist when the IC is reloaded.

Examples

Basic marquee

line1:
line2: [MC2999]
line3:
line4:

Starts at position 1 and advances through all three outputs each time the IC receives an input trigger.

Reverse marquee

line1:
line2: [MC2999]
line3: 2
line4: Reverse

Starts at position 2 and cycles backwards through the outputs.
