Struct I2c

pub struct I2c { /* private fields */ }

NuttX I2C Bus

Implementations

impl I2c

NuttX Implementation of I2C Bus

pub fn new(path: &str, frequency: u32) -> Result<Self, i32>

Create an I2C Bus from a Device Path (e.g. “/dev/i2c0”)

Trait Implementations

impl Drop for I2c

NuttX Implementation of I2C Bus

fn drop(&mut self)

Close the I2C Bus

impl Read for I2c

NuttX Implementation of I2C Read

type Error = i32

Error Type

fn read(&mut self, _addr: u8, _buf: &mut [u8]) -> Result<(), Self::Error>

TODO: Read buf from I2C Port

impl Write for I2c

NuttX Implementation of I2C Write

type Error = i32

Error Type

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

Write buf to I2C Port. We assume this is a Write I2C Register operation, with Register ID at buf[0]. TODO: Handle other kinds of I2C operations

impl WriteRead for I2c

NuttX Implementation of I2C WriteRead

type Error = i32

Error Type

fn write_read( &mut self, addr: u8, wbuf: &[u8], rbuf: &mut [u8], ) -> Result<(), Self::Error>

Write wbuf to I2C Port and read rbuf from I2C Port. We assume this is a Read I2C Register operation, with Register ID at wbuf[0]. TODO: Handle other kinds of I2C operations
