Struct CdcAcmHost 

pub struct CdcAcmHost<D: UsbHostDriver> { /* private fields */ }

CDC ACM host driver.

Provides read/write access to a CDC ACM (virtual serial port) USB device.

Implementations

impl<D: UsbHostDriver> CdcAcmHost<D>

pub fn new( driver: &D, config_desc: &[u8], device_address: u8, max_packet_size_0: u16, ) -> Result<Self, CdcAcmError>

Create a new CDC ACM host driver.

Parses the config descriptor to find CDC ACM endpoints and allocates channels.

pub async fn set_line_coding( &mut self, coding: &LineCoding, ) -> Result<(), CdcAcmError>

Set the line coding (baud rate, data bits, parity, stop bits).

pub async fn set_control_line_state( &mut self, dtr: bool, rts: bool, ) -> Result<(), CdcAcmError>

Set the control line state (DTR, RTS).

pub async fn read(&mut self, buf: &mut [u8]) -> Result<usize, CdcAcmError>

Read data from the CDC ACM device.

pub async fn write(&mut self, data: &[u8]) -> Result<usize, CdcAcmError>

Write data to the CDC ACM device.

Trait Implementations

impl<D: UsbHostDriver> ErrorType for CdcAcmHost<D>

type Error = CdcAcmError

Error type of all the IO operations on this type.

impl<D: UsbHostDriver> Read for CdcAcmHost<D>

async fn read(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>

Read some bytes from this source into the specified buffer, returning how many bytes were read.

async fn read_exact( &mut self, buf: &mut [u8], ) -> Result<(), ReadExactError<Self::Error>>

Read the exact number of bytes required to fill buf.

impl<D: UsbHostDriver> Write for CdcAcmHost<D>

async fn write(&mut self, buf: &[u8]) -> Result<usize, Self::Error>

Write a buffer into this writer, returning how many bytes were written.

async fn flush(&mut self) -> Result<(), Self::Error>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

async fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write an entire buffer into this writer.
