Overview

A helper class that represents I2C addresses.

An address instance remembers whether it was constructed as a seven-bit or ten-bit address. This attribute can be used by Initiators to determine the i2c addressing style to transmit.

Note: Per the above, a ten-bit constructed instance may still have an an address of seven or fewer bits.

#include "pw_i2c/address.h"
 
constexpr pw::i2c::Address kAddress1 = pw::i2c::Address::SevenBit<0x42>();
uint8_t raw_address_1 = kAddress1.GetSevenBit();
 
const pw::i2c::Address kAddress2<0x200>();  // 10-bit
uint16_t raw_address_2 = kAddress2.GetAddress();
// Note: kAddress2.GetSevenBit() would fail an assertion here.
