As long as the EEPROM receives an acknowledge, it will continue to increment the data word address and serially clock out sequential data words. When the memory address limit is reached, the data word address will “roll over” and the sequential read will continue. The sequential read ...

1.current read 2.sequential read 3.random read 其中1和2可以直接通过read系统调用实现 3.的话就需要通过ioctl(,I2C_RDWR,)来实现。 上述程序就是实现这个功能的,可以实现at24c02的random read。 random read ./rat24 0 256 表示从at24c02的word address为0的地址开始读取256个字节数据 ...
