If you are using a C++ compiler make sure the vector table is correct, and the name of the IRQHandler is not mangled by the compiler. Check the .MAP file. Unfortunately the code you provided is incomplete, the following was tested for the interrupt functioning on a VL-Discovery board. //...

HAL_DMA_IRQHandler(&hdma_adc1); 所以实际上,我们没有进行中断的处理,在初始化函数中,调用 uint32_tADC_ConvertedValue[ADC_NUMOFCHANNEL];……HAL_ADC_Start_DMA(&hadc1,ADC_ConvertedValue,ADC_NUMOFCHANNEL); 这样,当ADC8个通道的值采集完成以后,自动会交给DMA,而DMA直接将数据保存到ADC_ConvertedValue中。
