Hello Everyone, Please is it possible to trigger an adc conversion in DMA mode using external interrupt from gpio pin . I am using stm32f303re.

Yes it is.

In CubeMX you can see what external triggers could the ADC have.

Im sure there is a better way to address your problem but you could trigger the ADC with a "Regular Conversion Launched by software" inside your EXTINT callback

Then you can just configure the DMA to take care of the ADC readings as they come

Thank you very much @Javier Muñoz​ . I will try this out
