Stack Overflow Asked by Zachary Kennedy on February 10, 2021
I have two serial devices that I’m trying connect to my Raspberry Pi 3. The only issue is that hardware wise, the Raspberry Pi 3 is only built for one serial connection. That being said, I’m trying to use two of the unused GPIO pins on the Pi and bit-bang them, so I can use them for a second serial device.
I’m completely lost on how to do this? Can anyone help? Thanks!
