Based on 149 SCM AT24C02 (I2C protocol) experiments, CPU sends data to the IIC bus, followed by another from the IIC bus to read and display digital pipe actually operate the EEPROM. Device is attached to the IIC bus, , the write data, the host sends to wait until after the response from the machine in order to continue to issue the data signal, otherwise stop () read data, the host receives data from the machine, may complete the IIC bus, the host response in order to continue to read Data! ! !
