NuttX I2C Struct

Implementations

impl I2c

New NuttX 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

Drop NuttX SPI Bus

fn drop(&mut self)

Close the SPI Bus

impl Read<u8> for I2c

NuttX I2C Read

type Error = ()

TODO: Error Type

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

TODO: Read buf from I2C Port

impl Write<u8> for I2c

NuttX I2C Write

type Error = ()

TODO: 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<u8> for I2c

NuttX I2C WriteRead

type Error = ()

TODO: 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
