Serial interface for the Propeller
The Propeller prototyping board described elsewhere in this issue needs a programming interface, just like the board available from Parallax. The manufacturer offers the Propeller Plug and the Propeller Clip for this purpose. They can be used to link the board to a PC via a USB port. These mini-boards are fitted with an FTDI FT232 IC, which has appeared quite regularly in the magazine. The difference between the Plug and the Clip is in how they connect to the processor board.
