Re: LPC2106 interfacing with FT232BM USB chip questions

2004-09-29 by Gus

You can use TX and RX only but you want to watch out for UART speed 
as FT232 can run really fast. It would be a lot better if you use 
handshaking lines CTS and RTS, or at least CTS. If your application 
require real time then you would need to use RI (ring) as this pin 
will empty the FT232 buffer without waiting for timeout. DTR can be 
used as a digital output to control something like reset, boot 
loader...etc.

Good luck
