1. For backup register you can write any value you want. Just make sure you check for the same value after reset.

2. Obviously you need an external battery, if you want to keep time when the controller is off. You can connect a 3V battery to Vbat pin.

3. The RTC in F103C8 have some issues with keeping date. I can't do anything about it.. it needs to be fixed from ST.

All your videos are so clear and understandable you are very good about this.

[sysHW]

Thank you man, God bless you. This video so useful .

do i just connect a 3.3v to v bat if i want to keep track of time when the controller is off ?
what is the code i need to achieve that ?

[muhamadfauzirochmatullo]

thank you for this video, can i make gTime in algorithm? i want to make every 12 PM to 17.00 PM there is variable that will be change.. how do we write in keil u vision?

Thank you. How to set multiple alarms?

Hello, how can I program an alarm for all days of the week?


Thank you for the video!!

Can i do this using a STM32F207VCT6 Uc? or do i need to change the clock configuration?

[dioadadosite]

How can I make the code to read the data from my bmp280 sensor on an lcd display like the one you used?... I can't find the code.

Hi, it works very well with my F407VET6 .

Hi, i am working on a NUCLEO Board with STM32L433. I use the LSE oscillator as clock for the RTC. I have connected a capacitor to the Board and removed SB61. The capacitor gets charged by the Board (i selected 1.5 kOhms resistor). The RTC works fine, but when i press the reset button, the RTC gets reset. Writing and Reading the BR works but after a system reset there is another value than 0x32F2 in the BR and i do not knwo why. Can you help me with this problem?
Thanks in advance
Max

The Alarm dont work for me :S i got the F401RE there are something different to do?

So helpful ! Thank you so much. I did succeeded to run RTC on STM32f103c8t6.

[my_google_arifkhan]

my code works fine but how can i make time to 00:00:00 and than increase or decrease the time and than set it to any value manualy and than escape

THX, could you show how to adapt arduino librarys for stm32.Thanks again.

Hi sir, I just write the code for alarm and am not using any LCD to display the string. I just toggled the LED to indicate the alarm. But unfortunately the LED is not toggled even the callback function is used. Could you please explain me why it is happening?

[wtlyxeu]

Thank you man, Please Make a Video on External Crystal RTC Calibration

[bayuyutub]

hello..
i'm using NucleoL412KB and it's code not work
always my rtc time is reset..
please help me..
i'm using stanby mode

[bautroiEM]

could you build perpetual calendar in STM32 please

[Bianchi]

How can I save the clock, everytime I turn it off it returns to the time on my init code ??
thanks
