Resolved! STM32L152 - random EEPROM deletion at low voltage?

Dear,we use EEPROM in our project with STM32L152. It seems like in some MCUs is erased random part of the Eeprom. It happens very rarely, and probably most likely when VCC is disconnected from PCB (MCU). Any solution, any similar experience?Best rega...

EEPROM emulation error when using TIM timebase

I am using the example project from the xcube eeprom v3.0.0 as a reference to add EEPROM emulation to my project using the STM32G431RB. The example project works fine, but my project uses FREERTOS so I have changed my timebase source to a timer. This...

How to fix the I2C slave issue with STM32G070? HAL_I2C_ListenCpltCallback, HAL_I2C_AddrCallback, HAL_I2C_SlaveRxCpltCallback, HAL_I2C_SlaveTxCpltCallback

Hi, I'm trying to setup a stm32g070kb (32pin) MCU as I2C slave by using CubeIDE.I would like to create a code which will work same as I2C Eeprom, but when I ask the stm32 (with another MCU) to return me a register or registers value, the returned reg...
