SysTick

Hi guys, I am trying software timers without using interrupt

SysTick->CTRL = 0x5;

SysTick->LOAD = 0xFFFFFF;

SysTick->VAL = 0;

when start the program, what will happen with SysTick->VAL = 0;

it is value start with 0xFFFFFF or 0?

Can you not simply observe and see experimentally?

The SysTick is a 24-bit DOWN COUNT, it typically loads the value specified, and when it gets to zero it interrupts and reloads.

Better study the RTC then.

Try to use interrupts with timers.

Interrupts is something important to learn.
