  • Header: Always 0xAA
  • Command: Command byte (see table below)
  • ID: Display ID (0x00 for direct connection, 0xFE for broadcast)
  • Data Length: Number of data bytes (0-16)
  • Data: Command-specific data bytes
  • Checksum: (Command + ID + Data Length + Sum(Data)) & 0xFF

Response Format

Standard ACK/NAK response format:

[Header] [0xFF] [ID] [Data Length] [ACK/NAK] [Original Command] [Response Data...] [Checksum]
  • ACK: 0x41 ('A')
  • NAK: 0x4E ('N')
