Description: 基于149单片机的AT24C02(I2C协议)实验，CPU向IIC总线发送数据，之后再从IIC总线读取并显示在数码管上，实际上操作的是EEPROM.器件挂接在IIC总线上，写数据时，主机发送后得等到从机应答信号才能进行继续发数据，否则stop()；读数据时，主机接收到从机数据时，得主机完成IIC总线的应答才能继续读取数据-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! ! !
