You wont need a level translator with the FTDI chip. It will directly interface to the PIC, and the FTDI directly interfaces to the USB port with the right support components which are just a handful of passives. The trick is whether or not the FTDI will be powered by the USB port or by the PIC circuit. cheers Tony On Tue, Nov 14, 2017 at 11:56 PM, Richard Pope wro= te: > Clint, > I'll do that this evening after I get up.
