Can Any GPIO pin be used for UART communication.

[Tom Hill]

Currently by default I use the XBEE_DOUT, XBEE_DIN pins for serial communication. Is it possible to switch to a different GPIO pins for serial communication at run time, based on certain conditions?

Thanks,
Yogesh

Yogesh,

You’d need to emulate a UART in software. We don’t have any software support for that.

I did find this repo in mbed

https://developer.mbed.org/users/Sissors/code/SoftSerial/

Sissors is pretty active in the mbed ecosystem and puts out a lot of good code. You could give that repo a try.

Cheers,

Mike
