    Hi. I could not. This is what my problem looks like: in the Master (Nucleo STM32F030R8 board), the program execution does not reach the line “HAL_I2C_Master_Sequential_Receive_IT…” because the HAL status is HAL_I2C_STATE_BUSY_TX (0x21U). The Slave (Nucleo STM32G071RB board) does not call the HAL_I2C_AddrCallback callback. The reason is not clear to me. Did you solve the problem?

    HAL_TIM_PeriodElapsedCallback runs at 244Hz. It is impossible to notice such a blinking frequency of the diode with the eye. I lowered the work frequency to 10 Hz and saw the diode blinking
