Unable to Read and Write to I2C AT24C256[EEPROM] & STM32L412KBU6

[Kai_Satone]

Hello I am working with AT24C256[EEPROM] & STM32L412KBU6. But I am not able to write sequentially to the EEPROM, or read.

This is the code files
I tryet to chang the code but still unable to Read and Write

Why not? What happens when you try to do so?

Is the EEPROM responding to a HAL_I2C_IsDeviceReady call?

Are read/write functions returning HAL_OK or do they indicate an error?
