Additional ADC1 interrupts

In terms of number of interrupts, the STM32F302 has what appears to be one interrupt for Analog conversions, the �ADC1_IRQn�.  Can that be changed? I was thinking that optimally I would like one interrupt for starting the ADC conversions and then one more for the completion of the interrupts.  Do I have to use the ADC1_IRQn interrupt and follow the entire ADC conversion from start to the finishing point where it writes the data to the struct we have created from the JSQR1-4 registers?

Thanks! #nucleo #stm32f302

If you are sampling multiple channels, then use the DMA TC interrupt to indicate once they are all completed. Don't use the ADC EOC interrupt.
