Using pins 30/31 after boot with FT232BL
I copied the schematic from the demo board, in which the FT232 takes its power from the USB cable. The FTDI will be unpowered IF unplugged right? Assuming this is the case and the Prop Rx will be sitting low with no FT232 keeping it high, what is a method to accommodate all the various scenearios of states?
1. FT232 powered, unpowered
2. Remote serial device on, off
An AND only works if the FT232 is always on, and the remote device is always ON, not a given
An OR only works if the FT232 is always off, and the remote serial device is ON, not a given
