Trait i2c::BlockTransfer

pub trait BlockTransfer: Master {
    fn i2c_read_block_data(
        &mut self, 
        command: u8, 
        value: &mut [u8]
    ) -> Result<usize, Self::Error>;
    fn i2c_write_block_data(
        &mut self, 
        command: u8, 
        value: &[u8]
    ) -> Result<(), Self::Error>;
}

Basic I2C transfer without including length prefixes associated with SMBus.

Required Methods

fn i2c_read_block_data(
    &mut self,
    command: u8,
    value: &mut [u8]
) -> Result<usize, Self::Error>

Reads a block of bytes from the designated device register.

Unlike smbus_read_block_data this does not receive a data length.

fn i2c_write_block_data(
    &mut self,
    command: u8,
    value: &[u8]
) -> Result<(), Self::Error>

Writes a block of bytes to the designated device register.

Unlike smbus_write_block_data this does not transfer the data length.
