I2C总线上的每个设备都有自己的独立地址,主机发起通讯时,通过SDA信号线发送设备地址(SLAVE_ADDRESS)来查找从机。 I2C协议规定设备地址可以是7位或10位,实际中7位的地址应用比较广泛。紧跟设备地址的一个数据位用来表示数据传输方向,它是数据方向位(R/),第8位或第11位。数据方向位为“1”时表示主机由从机读数据...

最后,强调一下,EEPROM 支持的页写入只是一种加速的I2C 的传输时序,实际上并不要求每次都以页为单位进行读写,EEPROM 是支持随机访问的(直接读写任意一个地址),如前面的单个字节写入。在某些存储器,如NAND FLASH,它是必须按照Block 写入的,例如每个Block 为512 或4096 字节,数据写入的最小单位是Block,写入前都需要...
