Calculation of RTC in certain months(Months with 31)

[baris.akpinar]

Hello everyone,
In my sample project I have created, RTC does not perceive certain months as 31 days. Although it is 31 days in July, October, December, I took the same result in my essays with a code sample with an RTC code.I don't have problems in January, March, and August.
What are your ideas?

July 30 -> 01 august (Problem)

Func:

HAL_RTC_SetTime(&hrtc,&updateTime,RTC_FORMAT_BIN);

HAL_RTC_SetDate(&hrtc,&updateDate,RTC_FORMAT_BIN);

Card I used: F407VG 168mhz

Sure you're not setting the month off by 1? What is your code to set the date to july 30th?

I set up RTC for the time I wanted and then read it.

updateTime.Seconds=SECONDS; // 45

updateTime.Minutes=MINUTES; // 59

updateTime.Hours =HOUR; //23

updateDate.Date = DAY; // 30

updateDate.Month = MONTH; // 06

updateDate.Year = YEAR;

HAL_RTC_SetTime(&hrtc,&updateTime,RTC_FORMAT_BIN);

HAL_RTC_SetDate(&hrtc,&updateDate,RTC_FORMAT_BIN);

July is 7, not 6.

My problem is still going on.

Did you fix your code?

Not sure what you're looking for here. The off-by-one error was clearly the issue.

July = 6(Including zero)

My problem was solved, it was wrong to start the months, including zero.Thanks. I'm sorry for my bad english.
