The nRF GPIO output pins support a "high drive" mode for low and high push-pull outputs individually. A high-drive output can source more current, and thus has a faster transition than "standard drive". I needed this for experimenting with the MicroBit v2 speaker output pin.
Right now, this crate supports only "standard drive" push-pull outputs. This non-breaking pull request add an
.into_push_pull_output_drive()
method to pins, with an extra configuration argumentDriveConfig
. This is kind of gross, but was chosen to avoid changing.into_push_pull_output()
.I would be happy to add tests, but would need some tutoring to understand exactly how. Bikeshedding is also quite welcome.
