Module uarte

Expand description

Universal Asynchronous Receiver Transmitter (UART) driver.

The UART driver is provided in two flavors - this one and also crate::buffered_uarte::BufferedUarte. The Uarte here is useful for those use-cases where reading the UARTE peripheral is exclusively awaited on. If the Uarte is required to be awaited on with some other future, for example when using futures_util::future::select, then you should consider crate::buffered_uarte::BufferedUarte so that reads may continue while processing these other futures. If you do not then you may lose data between reads.

An advantage of the Uarte has over crate::buffered_uarte::BufferedUarte is that less memory may be used given that buffers are passed in directly to its read and write methods.
