STM32L: working with ADC and DMA . Enter to stop mode when the system is not busy, every 1-2 seconds. When return from stop mode the ADC and DMA are not working. Now I initialize every time all the ADC channels and the DMA, I am looking for a better solution. 

Thanks for advice

Can't determine what you are doing by '' I initialize every time all the ADC channels''. On entering stop mode, disable the ADC then DMA. On return enable DMA then ADC.

If that doesn't work, post your code.
