====== Access AT24C EEPROM via I2C ======
<WRAP noprint><WRAP left box 60%>
//__About this Article__//... orial, an approach for accessing AT24C EEPROM via I2C bus on is presented. Cubieboard1 or Cubieboard2 expand out groups of I2C pins which could be connected to peripheral I2C slave devices, like RTC dev... sible to connect serval slave devices on a single I2C interface, because I2C has the ability to communi
