17. 15 Jun 200617 Main tasks of AVR  receive commands from UI/Master and decode: –reprogram FPGA (Crosspoint Switch for DVI streams) –control DVI chips –redirect USB related commands to ARM board –handshake with Table Unit (at the moment not yet defined)

18. 15 Jun 200618 Code Development status May 8, 2006  Switch Unit and Table Unit handshaking (RS-232) not done (waits for spec. approval)  STUALIVE response not done (waits for spec. approval)  Video Command decoding might need minor adjusting for special cases (Beamer, Teacher, etc.)  Audio and Voting not done (branch structure is in place)  Unit programming should disregard a requirement to send Master signal every 200ms
