Struct SerialPortUart

pub struct SerialPortUart { /* private fields */ }

Implementation of the Uart trait on top of a serial device, such as /dev/ttyUSB0.

Implementations

impl SerialPortUart

pub fn open(port_name: &str, baud: u32) -> Result<Self>

Open the given serial device, such as /dev/ttyUSB0.

pub fn open_pseudo(port_name: &str, baud: u32) -> Result<Self>

Open a pseudo port (e.g. a verilator pts device).

Trait Implementations

impl ConsoleDevice for SerialPortUart

fn write(&self, buf: &[u8]) -> Result<()>

Writes data from buf to the UART.

fn poll_read(&self, cx: &mut Context<'_>, buf: &mut [u8]) -> Poll<Result<usize>>

Reads received data into buf, returning the number of bytes read.

fn set_break(&self, enable: bool) -> Result<()>

impl Uart for SerialPortUart

fn get_baudrate(&self) -> Result<u32>

Returns the UART baudrate. May return zero for virtual UARTs.

fn set_baudrate(&self, baudrate: u32) -> Result<()>

Sets the UART baudrate. May do nothing for virtual UARTs.

fn clear_rx_buffer(&self) -> Result<()>

Clears the UART RX buffer.

fn get_device_path(&self) -> Result<String>

Returns "/dev/ttyUSBn" or similar OS device path usable by external programs for directly accessing the serial port.

fn set_parity(&self, parity: Parity) -> Result<()>

fn get_flow_control(&self) -> Result<FlowControl>

fn set_flow_control(&self, flow_control: bool) -> Result<()>

Enables software flow control for writes.

fn get_parity(&self) -> Result<Parity>
