Although I have a specific application for the 40 way version of the controller, I was going to make the 8 Way Mains triac driver boards, universal for other projects, and have proper PCB's made for them. On reading Charle's much appreciated reply, I think just having I2C inputs to the boards (and 1 zero crossing output) is too limiting. I think I may crank up the project a little and use CNCMachineGuys suggestion of using a PIC instead to do the driving, with I2C, & Serial inputs to the board. At this time I might also have a go at cutting my teeth on USB interfacing, and add a USB input by using a PIC18F2458.

I dont have PBP3 (yet), does EasyHID work with version PBP 2.5 and Micro Code Studio Plus V2.2.1.1?
