Posted on May 17, 2011 at 14:02I ran into the same (lack of a SysTick disable mechanism) so I wrote my own.
FYI this function stops the SysTick counter (SysTick_CTRL_ENABLE_Msk)
and interrupts (SysTick_CTRL_TICKINT_Msk).You could just stop the interrupt if you want to leave the counter going.

void stm32_systick_disable(void)
{
SysTick->CTRL &= ~(SysTick_CTRL_ENABLE_Msk | SysTick_CTRL_TICKINT_Msk);
}
