Embassy

Embassy is a project to make async/await a first-class option for embedded development.

The embassy crate defines some traits.

embassy::io: Traits for byte-stream IO, essentially no_std compatible versions of futures::io.
embassy::flash: Trait for an async flash device.
More traits for SPI, I2C, UART async HAL coming soon.

The embassy-nrf crate contains implementations for nRF 52 series SoCs.

uarte: UARTE driver implementing AsyncBufRead and AsyncWrite.
qspi: QSPI driver implementing Flash.

Currently Embassy requires a recent nightly, mainly for generic_associated_types (for trait funcs returning futures) and type_alias_impl_trait (for returning futures implemented with async{} blocks). Stable support is a non-goal.

Why the name?

EMBedded ASYnc.
