Can I Use a Single Pin as Both Rx and Tx on an ATtiny85 for Software Serial?
Related question: I'll likely use an ATtiny85 for this project, meaning limited IO pins (WIP schematic pictured). I'll mostly be listening for signals with a software serial Rx pin, but would be nice to be able to use Tx periodically.
Is is possible to refine a single pin to use it as both Rx and Tx (though not at the same time)? Per some previous Arduino code - https://github.com/JeremySCook/arduino-experiments/blob/main/MIDI/1-inch-MIDI/2-inch-midi.ino

- I was able to set the Rx as the reset pin, which doesn't really function the way I set things up, so maybe it's possible. OTOH, SoftwareSerial is defined there outside of the setup function there, so I'm not sure if you can change this dynamically.
