I would like to add USB functionality to one of my PIC projects and I thought the best way of doing that would be to 'borrow' the USB bits of the NG circuit diagram :
I do have a few questions..
1- Am I missing out anything in the following circuit diagram? I tried to seperate the FT232 from the rest of the circuit, did I forget anything?
2- Can I just connect RTS# and DTS# to +5v (with the resistors)? Previously they connected to the RESET bit on the avr. What are these for?
3- What exactly is X3 (magenta circle)? is it just a wire link between CTS#, DSR#, DCD#, and RI# ?
I would appreciate any tips/suggestions/corrections.
