Адреса устройств на шине I2C
I2C (IIC) - последовательный интерфейс для связи интегральных схем, разработанная фирмой Philips.
I2C использует две двунаправленных линии, подтянутые к напряжению питания и управляемые через открытый коллектор (сток):
линия данных (SDA, англ. Serial DAta) и линия тактирования (SCL, англ. Serial CLock).
Классическая адресация включает 7-битное адресное пространство с 16 зарезервированными адресами. Это дает до 112 свободных адресов для подключения периферии на одну шину.
Все специализированные ИМС, поддерживающие работу в данном стандарте, имеют набор фиксированных адресов.
