As the above figure shows, the counter increases/decreases its value by one (depends on the counter mode) at each clock tick. Once the counter overflow (reach zero or ... If you mess with the core clock, for example slowing it down to save power then the SysTick frequency must be manually adjusted as well. You could use HAL_GetTick(): this function gets current SysTick counter value (incremented in SysTick interrupt) used by peripherals drivers to handle timeouts. I would suggest to do it with timer.Arduino Sketch: Blinking onboard LED every second using Timer1 Interrupt. Open your Arduino IDE and go to File > New to open a new file.
