Thread: TX-only Hardware Serial1?

    TX-only Hardware Serial1?

    Hi all!


    I am constructing a pin-intensive project using a Teensy 3.2. Upgrading to a larger board is not feasible due to space constraints.

    I was wondering if it is possible to override the use of the RX pin of Serial1 (pin 0) for either digital OUTPUT or INPUT mode, while continuing to use the TX pin 1 for Serial1 transmission.


    Thanks in advance!

    Yes, this was asked recently IIRC and posted answer indicated changing pinMode() after the Serial1.begin() will divert the pin to that usage.

    To confirm that post might be found with a search.

    Thanks defragster! Sorry, I couldn't find this post before, I'll have another look!
