Think I'm finally going to switch to FT231x for my P2 board.
Smaller and 1/2 the price although it does need two 27 ohm resistors that FT232R doesn't need.
But, looking at the P2-ES circuit diagram, looks like one needs to use FT_PROG utility to make the CBUS pins work as desired.
Does Parallax do this for every board they make?
Or, do they buy them preprogrammed?
BTW: I spent a lot of time seeing if FT93x could be used instead. Sadly, I don't think it is possible to make DTR work the same way.
It does have 4 com port interfaces though and one could be used to signal reset, but that's just a pain.
The other issue I found is that you can't make the UART automatically have the same baud as the virtual com port.
Would have been a lot of potential if not for these issues...
