Yes. You are right. May be someone wanted to auto-start their irrigation water-pump every day at 5am. It will auto-start even before they wake up from sleep. Whenever they wake up and feels enough watering, they can switch off by pressing the button. It will auto-start next day same time again and so on Thanks

@@NizarMohideen Can the MCU automically wake up at specific times in the day and go to sleep afterward to save power ?

HAL library is already included in STM32CubeIDE. We can simply use them. For example HAL_Delay(x); will delay by x milli seconds. Complete list of HAL Functions can be found below link www.st.com/resource/en/user_manual/dm00154093-description-of-stm32f1-hal-and-lowlayer-drivers-stmicroelectronics.pdf

Hi Nayan, Thanks for the comment. I don’t have an STM32L010 board with me at the moment. I am going to buy one soon. It will be few months by the time it arrive from overseas and I get familiar with the board.

You can set sate. You can get date RTC_DateTypeDef gDate; HAL_RTC_GetDate(&hrtc, &gDate, RTC_FORMAT_BIN);

@@NizarMohideen when I set the date it works, and when it starts without setup, why can't it? the result is day 0, month 1, date 1, year 0

@@NizarMohideen it keeps only time not date, can you help me? thanks

Do the similar things to date initialization as you done for the time code from second and subsequent uploads That is to comment out the date code except for the first upload
