• This library is only for Ynvisible Gen3 displays.
• For Gen1/Gen2 displays, use the legacy driver:
  https://github.com/Ynvisible-Electronics/YNV-Driver-v5-Arduino-Library
• Signage Kit support has been removed until the product is officially released.

This library enables full control of Ynvisible Gen3 electrochromic displays using the Driver v5 evaluation board.

It includes:

• Color and Bleach transitions
• Open‑circuit potential (OCP) sampling
• Automatic refresh engine
• Safe CE driving (DAC‑based virtual ground)
• Accurate LSB-based amplitude logic

• Ready-to-use control functions for:
  • 7‑segment (dot)
  • 15‑segment (negative & dot)
  • 3‑bars and 7‑bars displays

• LED animations
• Startup sequences
• Simple debug indicators
