I ask this question because I am already using all the i2c pins for my lcd screen and I need to write in EEPROM and it seems that I need to configure a I2C to use the hal function to write ...

i have a STM32L0VZ (UFBGA100) and I would like to know if I can ouput the RTC Calib on this PIN ?Thank you very much

To read the frequency I am using a timer to output frequency then I am reading the value using a frequence counter. I am using the stm32l083rz chip. I have a gate time of 32 seconds on my frequence counter.I am trying to compensate the drift due to t...

Yes I was willing to use the internal EEPROM, sorry if I wasn't precise enough ! Thank you @Community member and @Andrew Neil :D Have a great day !

Ok thank you for your answer, the answer to my issue is that with the hal function : HAL_FLASHEx_DATAEEPROM_Program() you can do what I wanted to do.

I saw that it was maybe possible to use a SPI pin, do you know if it is possible to write/read eeprom with SPI ?(thank you for your first answer btw)

Thank you JW that was it, indeed now I can see the effet of the calibration. I started to wonder If i was obligated to use the pin PC13 to have the result I wanted. But it seems that your way is working too. Thank you very much !Léo

I set the rtc to have an interuption every second and I am changing the value of a GPIO pin, that's the best way I found to read the RTC frequency.Here are my readings :x: time in minutesy: frequency in mHznb: for the 3 graphs on top I put the max va...

Have I to use an I2C pin to write into EEPROM ?

Can we output the RTC calib on pin PE3 on STM32L0 ?

RTC digital smooth calibration doesn't seems to work (stm32l083rz)
