default = rt

The rt feature is set by default whenever embassy-nrf is added without default-features = false somewhere in the dependency tree.

rt default

Cortex-M runtime (enabled by default)

Enables rt of optional nrf51-pac, optional nrf52805-pac, optional nrf52810-pac, optional nrf52811-pac, optional nrf52820-pac, optional nrf52832-pac, optional nrf52833-pac, optional nrf52840-pac, optional nrf5340-app-pac, optional nrf5340-net-pac, optional nrf9120-pac, and optional nrf9160-pac

time

Enable features requiring embassy-time

Enables embassy-time

defmt

Enable defmt

Enables defmt, defmt of embassy-embedded-hal, embassy-hal-internal, embassy-sync, and embassy-usb-driver

unstable-pac

Reexport the PAC for the currently enabled chip at embassy_nrf::pac (unstable)

gpiote

This is unstable because semver-minor (non-breaking) releases of embassy-nrf may major-bump (breaking) the PAC version.
If this is an issue for you, you're encouraged to directly depend on a fixed version of the PAC.
There are no plans to make this stable.

Enable GPIO tasks and events

Affects embassy-nrf::gpiote, embassy-nrf::Config.gpiote_interrupt_priority…

time-driver-rtc1 = _time-driver

Use RTC1 as the time driver for embassy-time, with a tick rate of 32.768khz

nfc-pins-as-gpio

Allow using the NFC pins as regular GPIO pins (P0_09/P0_10 on nRF52, P0_02/P0_03 on nRF53)

reset-pin-as-gpio

Allow using the RST pin as a regular GPIO pin.
* nRF52805, nRF52810, nRF52811, nRF52832: P0_21
* nRF52820, nRF52833, nRF52840: P0_18
