hi, i want to read and write data on EEPROM . This  eeprom interface with stm32f0. for these i used I2C bus.

there are any library or tutorial that can give how to read and write and interface ?

thank you

hello, first of all, you should study about i2c how it works then read-write from EEPROM will be easy. Read reference manual.

For EEPROM I2C bus based, maybe this will help

It's based on I2C generated by GPIO and SW from this note:

Hope this helps and suggestions welcome.

Good luck!

Hello,

You can found a full set of running examples with an I2C EEPROM within the

http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-embedded-software/stm32cubef0.html

firmware package which provides running applications showing how to use the I2C:
