I am going to implement the FTDI IC on the Propeller demo board but i want to make sure that the FTDI IC circuit is complete as shown in the book. It seems that the circuit is missing something but perhaps not? Just want someone to confirm that the 12 pins used are the only ones needed out of the 28 pins.

    I made a my own copy of the Prop plug using the prop demo board schematic. I copied it exactly leaving the unused pins and it works fine. Most of the other pins from what I could figure out from the spec sheet is for more complex circuits or to custom program it's firmware(?), or are programmable I/O pins for misc. You can make it a security dongle, etc.

    So if you are referring to something similar, it should work. Mine works great, except for the one smt led I burned a little with soldering iron. :(
