STM32F030C6 定时器16没有工作起来，求助各位，谢谢！配置如下：
void TIME16_Init()
{
TIM_TimeBaseInitTypeDef  TIM_TimeBaseStructure;
NVIC_InitTypeDef NVIC_InitStructure;
/* TIM16 clock enable */
   RCC_APB2PeriphResetCmd(RCC_APB2Periph_TIM16, ENABLE);

TIM_DeInit(TIM16);
/* Time base configuration */
   TIM_TimeBaseStructure.TIM_Period = 1500;
   TIM_TimeBaseStructure.TIM_Prescaler = 480-1;  //48M/480=100000HZ
   TIM_TimeBaseStructure.TIM_ClockDivision = 0;
   TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseInit(TIM16, &TIM_TimeBaseStructure);

NVIC_InitStructure.NVIC_IRQChannel = TIM16_IRQn;
   NVIC_InitStructure.NVIC_IRQChannelPriority = 0;
   NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);

TIM_ClearFlag(TIM16, TIM_IT_Update);
   TIM_ITConfig(TIM16, TIM_IT_Update, ENABLE);

//TIM_ARRPreloadConfig(TIM16, ENABLE);
   /* TIM16 enable counter */
   TIM_Cmd(TIM16, ENABLE);
}

不了解F0系列，定时器编号居然排到16、17？
真要刮目相看了。

F767 才到TIM14 你这F0都到16、17了。。。真是汗颜。。。

有的，这是数据手册上介绍：
TIM15/16/17 introduction
The TIM15/16/17 timers consist of a 16-bit auto-reload counter driven by a programmable
prescaler.
They may be used for a variety of purposes, including measuring the pulse lengths of input
signals (input capture) or generating output waveforms (output compare, PWM,
complementary PWM with dead-time insertion).
Pulse lengths and waveform periods can be modulated from a few microseconds to several
milliseconds using the timer prescaler and the RCC clock controller prescalers.
The TIM15/16/17 timers are completely independent, and do not share any resources. The
TIM15 can be synchronized with other timers.
