我用TIM3 ADC DMA 做了一个AD 采集，因为我TIM3 打算用做其他用途，所以准备把TIM3 换成TIM15 但是 一换成TIM15 DMA 中断就进不去了，我就查找原因，加了 TIM15 中断，但是 TIM15 中断确也进不去，请问哪位大侠知道是什么原因么

[看了你的代码，没发现明显异常。你确定是STM32F030K6吗？我试着CubeMX去配置，没发现TIM15啊。然后看数据手册，也没说它有TIM15. 手册有说别的芯片有。Available on STM32F030x8 and STM32F030xBdevices only.但它没有]*

是我自己搞晕了  STM32F030K6 根本没有TIM15
