• GEN2 displays.
• This library is maintained for customers who already own Gen2 displays and Evaluation Kits can continue using them with improved driving performance.
• Version 1.1.0 introduces an updated driving method.
• For modern Gen3 displays, use the GEN3 library:
  https://github.com/Ynvisible-Electronics/YNV-Driver-v5-Gen3-Arduino-Library

This library provides complete control of Ynvisible GEN2 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
