Hello, I tried to run the RTC DS1307 first using libraries available on the internet. It was not successful. Later I tried to run the communication "manually" but it doesn't work either. Please help. The module with DS1307 works on Arduino. Through t...

@KnarfB @Andrew Neil @Pavel A. Thank you all for your answers. It helped me to solve my problem.I know that an Oscilloscope or Logic Analyzer are helpful. As I mentioned - I ordered the device but don't get it yet - that's why I try with SQW outp...

Oh, for bats's snacks, it was the pull-up resistors. It cost me a few days :-(. One thing to note - Arduino works well with the module, STM does not :-(.R2 was missing.

Thank You for your answer.I tried this one: /* USER CODE BEGIN 2 */ const uint8_t DS1307_adress = 0x68; const uint8_t DS1307_config = 0x00; HAL_I2C_Mem_Write(&hi2c1, (uint16_t)(DS1307_adress<<1), 0x07, 1, &DS1307_config, 1, 1000); /* USER CODE END ...

I2C problem. I can't get the communication to work on STM32F0 Discovery in STM32CubeIDE. Where is the error in reasoning?
