You call EEPROM_Write() from the UART RX interrupt/callback. As an example, the code was used on an STM32F429 using the I2C3 peripheral (PA8 for SCL, PC9 for SDA) with a 24LC01B chip. License: Attribution. Ignoring the delay needed for the EEPROM to actually store the data, just the I2C transactions to send the data to the EEPROM take more time than you should spend in an interrupt function; And then you call HAL_Delay() from EEPROM_Write(), which is called from the UART interrupt/callback.
