各位大侠，我想用SysTick中断点个灯，但中断涵数好像根本没有，高手说下怎么写，中断0-31都不包含它哟

CMSIS Example
The following section shows a typical example for using the CMSIS layer in user applications. The example is based on a STM32F10x Device.

#include "stm32f10x.h"

volatile uint32_t msTicks;                      /* timeTicks counter */

void SysTick_Handler(void) {
  msTicks++;                                  /* increment timeTicks counter */
}

__INLINE static void Delay (uint32_t dlyTicks) {
  uint32_t curTicks = msTicks;

  while ((msTicks - curTicks) < dlyTicks);
}

__INLINE static void LED_Config(void) {
  ;                                           /* Configure the LEDs */
}

__INLINE static void LED_On (uint32_t led) {
  ;                                           /* Turn On  LED */
}

__INLINE static void LED_Off (uint32_t led) {
  ;                                           /* Turn Off LED */
}

int main (void) {
  if (SysTick_Config (SystemCoreClock / 1000)) { /* Setup SysTick for 1 msec interrupts */
;                                           /* Handle Error */
while (1);
  }

  LED_Config();                               /* configure the LEDs */

  while(1) {
LED_On (0x100);                            /* Turn  on the LED */
Delay (100);                               /* delay  100 Msec */
LED_Off (0x100);                            /* Turn off the LED */
Delay (100);                               /* delay  100 Msec */
  }
}
