[dependencies]
embassy-nrf = { version = "0.3.1", default-features = false, features = ["rt", "time", "defmt", "unstable-pac", "gpiote", "time-driver-rtc1", "nfc-pins-as-gpio", "reset-pin-as-gpio", "qspi-multiwrite-flash", "nrf51", "nrf52805", "nrf52810", "nrf52811", "nrf52820", "nrf52832", "nrf52833", "nrf52840", "nrf5340-app-s", "nrf5340-app-ns", "nrf5340-net", "nrf54l15-app-s", "nrf54l15-app-ns", "nrf9160-s", "nrf9160-ns", "nrf9120-s", "nrf9161-s", "nrf9120-ns", "nrf9161-ns", "log"] }

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 nrf-pac

time

Enable features requiring embassy-time

Enables embassy-time, time of embassy-embedded-hal

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.
