Hi Miguel,
Good to hear!
Yeah, GPIO is the only way I've ever implemented this and I think a
simple SW implementation is the way to go here.

Hi Kevin,
I actually do have some code for 1-wire I implemented a few days ago.
AFAIK most MCUs we support don't have 1-wire specific hardware, so why
not have a general implementation(using hal_timer) instead of one
implementation per MCU?
Thanks,
Miguel

Is there any interest is discussing how to add Dallas 1-Wire support to
the HAL? https://en.wikipedia.org/wiki/1-Wire
It's a bit of a niche item, but an interesting protocol (you can power
some devices from the single GPIO line) and there are some very common
and cheap waterproof temp sensors and a few other common items that are
only available in 1 wire.
I'm happy to put one or two test drivers together for common items like
the DS18B20 (https://www.adafruit.com/product/381) ... but the HAL
implementation is something that should probably be discussed with the
wider community first.
