robert-hh	b33f204529	samd/machine_uart: Add the machine.UART class. All board pins that have UART's assigned can be used. Baud rate range is 75 Baud to ~2 MBaud. No flow control yet, and only RX is buffered. TX buffer and flow control may be added later for SAMD51 with its larger RAM and Flash.	2022-10-06 22:48:12 +11:00

samd/machine_uart: Add the machine.UART class.

All board pins that have UART's assigned can be used.  Baud rate range is
75 Baud to ~2 MBaud.

No flow control yet, and only RX is buffered.  TX buffer and flow control
may be added later for SAMD51 with its larger RAM and Flash.
