Hello,

As reported in the picture attached, an error occurs while trying to edit the CSELR register of the DMA. It seems to lack of the definitions of several register...how can i solve it?

I am using NucleoSTM32L476RG and STM32IDE

Thanks

Channel selection is done in the CSELR register which is not a per-channel register. So DMA1_CSELR->CSELR. A bit awkward.
