| SOLVED: FT231X: CTS? |

I'm using a FT231X for the first time and having a bit of trouble ;) From the PC side connecting into the FT231X all is good and I can run FT-PROG etc. If I connect realterm I can send in characters and get one of the LEDs to flash (I think the labels are the wrong way around but that is not a big deal), however on the other side if I generate characters at the PIC side I do not get an LED flash and neither do characters appear at the terminal. I did not need hardware handshake so I left pins 19, 6, 18, 4, 5 & 2 disconnected. I'm starting to wonder if pin 19 or 6 should not have been left floating? |

The unused pins may be left floating. But this reset connection with C20 in series looks a bit strange to me. How is it connected to the uC? Are you sure the uC is working correctly, have you hooked up a scope or LA? |

I've dealt with this type of problem before. Lesson learned: Read the errata. :palm: Try configuring one CBUS pin as a #Keep_Awake through FT-PROG and short that pin to ground. |

Looks OK. There are things that I cannot see.. specifically under the QFN.... so I was doubting myself. |
