WebJan 30, 2024 · A for-loop for a delay is a crude and generally non-deterministic solution, with a period that will change between compilers, with different compiler options and on different targets or with different clock speeds. STM32 is a Cortex-M device and given that you should use the SYSTICK counter for this. For example, as a minimum something like: WebSep 18, 2024 · Set Alarms later. printf ("RTC backup available\n"); return; } /* USER CODE END Check_RTC_BKUP */ /** Initialize RTC and set the Time and Date */ //I didn't copy the rest of this function to make is shorter. } This is it. I use a backup register to remember that I have time, and check it. I DO NOT save time in any 0-19 register manually.
