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
