TIM10 11 13 14不能 输出PWM波

RT  求问大神 什么原因  在线等啊  多谢！
代码配置如下

void bsp_PwmGpioInit(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    /* GPIOC clock enable */
    RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOF, ENABLE);

PWM我没有怎么用过，你参考下官方V1.3.0固件库里面的PWM输出例子。

另:你把这个开启下试试TIM_CtrlPWMOutputs(TIM10, ENABLE);

哎  固件库有就好办了 ，我都是照着例程写的

例外 那个函数只支持TIM1 TIM8 没什么用
