Trait knurling_traits::i2c_master::I2cMaster

pub trait I2cMaster {
    fn read_bytes(
        &mut self, 
        address: u8, 
        output: &mut [u8]
    ) -> Result<usize, ()>;
    fn write_bytes(&mut self, address: u8, bytes: &[u8]) -> Result<usize, ()>;
}

A trait to define an I2C Master port behavior

Blocking vs. Non-blocking behavior is not defined for this trait.

Required Methods

fn read_bytes(&mut self, address: u8, output: &mut [u8]) -> Result<usize, ()>

Attempt to read up to output.len() bytes. Number of bytes read is returned. If an error is returned, no bytes are assumed to be read.

fn write_bytes(&mut self, address: u8, bytes: &[u8]) -> Result<usize, ()>

Attempt to write all given bytes. Number of bytes written is returned. If an error is returned, no bytes are assumed to be written If a NAK is encountered, writing will be stopped.
