Asynchronous serial communication using UART/USART peripherals
Word length
By default, the UART/USART uses 8 data bits. The Serial, Rx, and Tx structs implement
the embedded-hal read and write traits with u8 as the word type.
You can also configure the hardware to use 9 data bits with the Config wordlength_9()
function. After creating a Serial with this option, use the with_u16_data() function to
convert the Serial<_, _, u8> object into a Serial<_, _, u16> that can send and receive
u16s.
In this mode, the Serial<_, _, u16>, Rx<_, u16>, and Tx<_, u16> structs instead implement
the embedded-hal read and write traits with u16 as the word type. You can use these
implementations for 9-bit words.
