I need to interface my MC9S12XDP512 processor board with a peripheral device running a virtual com port via an FTDI FX230 USB peripheral chip. Any recommendations on the most expedient way to do this? I have looked at the FTDI Vinculum chip, but wanted to see if other solutions were available. The MC9S12 system will be used as a functional tester for a medium run board production (with the board under test containing the FTDI VCP USB peripheral). The USB transfer is just a few bites (send / receive) to validate USB functionality on the target boards.
