Project Status

Work Completed

• IR communication(Protocol, software, and hardware)

• RF communication(Software and Hardware)• Hardware(PCBs)– Pack– Tagger– Pylon– Central Computer

• Script interpreter

Work Completed (cont.)

• High level scripting language• Parser/compiler/linker• Remote procedural call• LCD interface• Communication between PC and devices• Ability to flash compiled script

Work Remaining

• System integration– IR and timer code

• Power circuit• Program Gametypes• Gui for admin and scripting front end

Problems Encountered

• BDM Programmer

• PCB Problems– Vdd and Vss– Foot prints– Power Circuit– Via sizes

Test and Evaluation

Difficulty Testing

• System testing– Incomplete hardware

• Module testing– Pack, Tagger…

• Component testing– ICs and passives

Demo Milestone

• Protoboard Demo– Tagger– Pack– Central Computer

Compiler Testing

• Test Bench
