[SOLVED] read and writing to EEPROM using I2C

[Raady Here]

Hi,

I written code for I2C protocol that read and write to an EEPROM 24LC256.

How it varies writing or reading to EEPROM driven by interrupt or polling method ?

Is there any advantage over the other ?

Is there links where I can read in detail about this ?


Regards,
Raady.

Which Compiler do you use? There is no need for interrupt. I2C is used. You read and write whenever you want. So, no need of interrupt. Ofcourse, you can use interrupt for reading and writing from/to eeprom.

you don't need to do any polling on i2c, clock is in your hand so just simply read and write. Interrupt can also be used (if your MCU supports I2C interrupt), but that is normally not needed for simple applications.
