Expand description

Advanced I2C transfer queues that support repeated START operations.

Required Methods§

Source

fn i2c_transfer_support( &mut self, ) -> Result<(ReadFlags, WriteFlags), Self::Error>

Specifies the flags that this implementation supports.

Source

fn i2c_transfer( &mut self, messages: &mut [Message<'_>], ) -> Result<(), Self::Error>
