Protokoll

  • Hersteller-Id, Geräte-Id?
Intialisierung

noch unbekannt

Datenübertragung
  • USB Bulk
  • Frames werden in mehreren Paketen übertragen,
  • wenn ein Frame fertig ist, wird ein leerer bulk transfer durchgeführt.
  • LE (little endian), immer 2 Bytes
  • Farbtiefe ist 15 Bit → 5 Bit pro Farbe
  • Hardware hat Probleme mit durch 4 teilbaren Paketgrößen oder so, ggf. ein silicon bug oder ich mach was falsch :)
  • 2 Modes, unterschieden wird durch das höchstwertigste Bit (0x8000):
    • setze ein Pixel in Farbe (rgb) (höchstes Bit = 1)
      • r = in >> 10 & 0x1F;
        g = in >>  5 & 0x1F;
        b = in       & 0x1F;
    • wiederhole das letzte Pixel n mal (höchstes Bit = 0)
      • n = in & 0x7FFF;
  • Wir können nach erfolgreicher Initialisierung durch den Originaltreiber Frames injekten.
