$ARGUMENTS

What This Expert Covers

Implementation & Design

  • LED Strip Control: WS2812, SK6812, APA106, and custom LED protocols
  • Encoder Architecture: Copy, Bytes, Simple Callback, and Custom Composite encoders
  • Multi-Channel Sync: Coordinated transmission across multiple outputs
  • IR Remote Control: NEC, RC5, and other infrared protocols

Migration & Modernization

  • RMT4 to RMT5 Migration: Convert legacy code to new encoder-based architecture
  • API Translation: Channel handles, symbol structures, clock configuration

Debugging & Troubleshooting

  • Common errors: encoding artifacts, clock source mismatch, timing inaccuracies
  • System crashes: Cache safety, IRAM placement, flash operation conflicts
  • Performance issues: DMA configuration, encoder optimization

Configuration & Optimization

  • Timing calculations, resolution selection, duration encoding
  • DMA setup, buffer sizing, alignment requirements
  • Hardware limits across ESP32 family (ESP32, S2, S3, C3, C6, H2)

What You'll Get

  • Complete code examples with detailed comments
  • Timing calculations showing duration/resolution conversions
  • State machine diagrams for custom encoders
  • Hardware compatibility analysis for your target chip
  • Testing strategies with edge cases and validation steps
