I have an DLP-USB232M evaluation board, for the FTDI serial to USB IC. I am attempting to build a small PCB board and connect this IC to a microcontrollers serial output. So far, things seem straightfoward, however, the DLP-USB232M has two pins I am not clear about.
PIN 21 CTS#(IN) Clear to send Control INput/ Handshake Signal
PIN 22 RTS#(OUT) Request to send Control Output/ Handshake signal.
As far as I understand, I will need to write to PIN 21 when I can receive input and read pin 22 when I want to send input, so I can just hook these two pins up to some unused port pins on my MEGA8 and worry about the particulars when I get to the software.
Does that sound correct?
Thanks and much appreciated,
