rp2040 uart0 + uart 1

	//! # UART Example
	//!
	//! This application demonstrates how to use the UART Driver to talk to a serial
	//! connection.

	//! It may need to be adapted to your particular board layout and/or pin
	//! assignment.
	//!
	//! See the `Cargo.toml` file for Copyright and licence details.

9names / Notes.txt

Created December 24, 2021 05:50

Test code for review https://github.com/rp-rs/rp-hal/pull/210

	uart1_pins_split-join_flow-control.rs: configuring pins as TX/RX/CTS/RTS, split and join functions, UART HW flow control
	uart0_split_flow-control.rs: test UART HW flow control on UART0 but uses split TX/RX for all operations
	flow_control_debugging.rs: attempting to work out if we could unblock UART after errors (unsuccessfully)

	I also tested without the CTS/RTS pins enabled, and that worked fine (HW flow control is currently always enabled)
