⚙️ CASE 15 Overview
- Triggered when B1–B4 = 1111 (
🔴🔴🔴🔴) - The frame must include at least 5 bytes total
- Bytes 1–4: Fixed structure (bank, timing, brightness, etc.)
- Byte 5 (L command byte): Determines the specific CASE 15 behavior
- Additional bytes may be used depending on the command
🧠 What makes it different?
- CASE 15 uses additional bytes in the frame to define dynamic behavior
- It’s essentially a mini-program embedded in your animation
- This enables advanced logic such as:
- Looping a range of frames (mini-loops)
- Switching memory slots mid-sequence
- Overriding brightness, speed, and fade temporarily
- Triggering timed or reactive lighting effects
⚠️ Important Notes:
- CASE 15 is powerful but risky if misused
- If the data bytes are missing, invalid, or misaligned, you may experience:
- – Skipped frames
- – Frozen LEDs
- – Unstable or broken playback
- No app safeguards are currently in place, so test carefully
📘 CASE 15 Command Table
| Command Name | Bits | What It Does |
|---|---|---|
| MiniLoop Start | L17–L24 | Defines the start frame for a mini-loop. Must be ≥2 and less than total frames. |
| MiniLoop Count | L25–L32 | How many times to repeat the mini-loop. Range: 1–255 |
| Memory Slot | L13–L16 | Switches to a new memory bank or sequence slot (1–15) |
| Set Brightness | L1–L4 | Temporarily overrides brightness level. Range: 1–15 |
| Set Speed | L5–L8 | Temporarily overrides playback speed. Range: 1–15 |
| Fade In | L9–L10 | Sets fade-in style: 0 = instant, 3 = very slow |
| Fade Out | L11–L12 | Sets fade-out style: 0 = instant, 3 = very slow |
🧩 Example:
You might use CASE 15 to loop frames 2–6 three times, or to temporarily dim all LEDs during a strobe effect.
