This TSU-7000 PCF template is an update to my earlier TSU3000 system and follows the Tonks standard, with his graphics (and a few others) linked to the IR codes located under a hidden "CODES" tab.
I have a fairly simple setup - only 4 primary devices (Denon & Sammy) are unused in the background, with some macros used for the TV where discretes weren't available. Please note that I use the hard buttons for channel up/down, volume up/down, and mute - so these commands do NOT show up on the graphics screens. I have rearranged several of the layouts to get as much functionality on each primary screen as possible - some of the buttons are a little smaller than I'd like, but work well when controlled by a fingernail OR one of the small plastic styluses found with any of today's touch-screen PDAs (Palm, HP, etc).
There are a few less-than obvious connections - using the page markers - to get to some hidden pages I wanted access to, but not obvious for the kids (raw codes pages, and other debugging stuff). Have fun!
