The SysTick_Config() function is a CMSIS function which configure: - The SysTick Reload register with value passed as function parameter. - Configure the SysTick IRQ priority to the lowest value (0x0F). - Reset the SysTick Counter register. - Configure the SysTick Counter clock source to be Core Clock Source (HCLK). - Enable the SysTick Interrupt. - Start the SysTick Counter. 2. You can change the SysTick Clock source to be HCLK_Div8 by calling the SysTick_CLKSourceConfig(SysTick_CLKSource_HCLK_Div8) just after the SysTick_Config() function call. The SysTick_CLKSourceConfig() is defined inside the misc.c file. 3. You can change the SysTick IRQ priority by calling the NVIC_SetPriority(SysTick_IRQn,...) just after the SysTick_Config() function call. The NVIC_SetPriority() is defined inside the core_cm3.h file. 4. To adjust the SysTick time base, use the following formula: Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s) - Reload Value is the parameter to be passed for SysTick_Config() function - Reload Value should not exceed 0xFFFFFF */ if (SysTick_Config(SystemCoreClock / HzPreSecond)) { /* Capture error */ while (1); } } /**------------------------------------------------------- * @函数名 SysTickDelay * @功能 系统定时器实现的延时函数，可以在用户程序中调用 * 用户可以根据需要修改 * @参数 延迟周期数，延迟时间为nTime/HzPreSecond * 误差为 -1/HzPreSecond * @返回值 无 ***------------------------------------------------------*/ void SysTickDelay(__IO uint32_t nTime) { TimingDelay = nTime; while(TimingDelay != 0); } /**------------------------------------------------------- * @函数名 TimingDelay_Decrement * @功能 系统节拍定时器服务函数调用的子函数 * 将全局变量TimingD
