Document performance analysis and implementation details for GC9A01, ST7789, and ST77961 (ST77916) display drivers. Includes:

  • Architecture overview with class hierarchy
  • Driver-specific initialization sequences and register commands
  • Performance bottleneck analysis (DMA, window caching, color conversion)
  • Platform-specific optimizations for ESP32 and RP2040
  • Best practices for high-performance drawing
  • Troubleshooting guide and compatibility matrix

This guide is designed to help LLMs and developers implement TFT displays professionally using the LovyanGFX library.

hi,

thanks for creating this guide 👍

please use the develop branch for any submission

some additional thoughts:

  • there's a '/doc' folder which seems a better place to leave markdown files
  • TFT_DISPLAY_IMPLEMENTATION_GUIDE.md should probably be renamed to something more specific e.g. TFT_DISPLAY_IMPLEMENTATION_GUIDE_GC9A01_ST77xx.md
