STM32F407ZGT6的TIM9-14中断例程

STM32F407ZGT6的TIM9-14STM32F407ZGT6的TIM9-14中断例程应该怎么写？

寄存器版本下的中断配置MY_NVIC_Init和中断服务函数怎么写?

没有找到类似TIM9_IRQHandler和TIM9_IRQn的定义，只找到了TIM1_BRK_TIM9_IRQHandler和TIM1_BRK_TIM9_IRQn的定义。

难道TIM1 break和TIM9公用一个中断而在服务函数里同过对寄存器判断来区分是哪个中断？

综合实验不是我需要的参考。

通过实验验证了我的猜测。

发个比较强大的SetTimer吧，设定计时时间，次数，完成时的执行体，成功后返回id 缺点：计数器使用紧张时有可能短计时占用长时间计时器从而导致新的长时间计时申请不到计时器
