virtual int	get_port () const =0
	Returns the I2C port number.
Public Member Functions inherited from esphome::i2c::I2CBus
virtual	~I2CBus ()=default
virtual ErrorCode	write_readv (uint8_t address, const uint8_t *write_buffer, size_t write_count, uint8_t *read_buffer, size_t read_count)=0
	This virtual method writes bytes to an I2CBus from an array, then reads bytes into an array of ReadBuffer.
ErrorCode	read (uint8_t address, uint8_t *buffer, size_t len)
ErrorCode	write (uint8_t address, const uint8_t *buffer, size_t len, bool stop=true)
