This is an interrupt handler. The HAL libraries will manage the main interrupt service routine (ISR) when the timer interrupt occurs (feel free to examine it in stm32l4xx_it.c). At some point in that ISR, the code will call HAL_TIM_PeriodElapsedCallback(), which we ...

The correct choice is to use a Hardware Timer with Interrupt to call your function.These hardware timers, using interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using ...
