Which MDMA channel use?

[rubenles]

Hello! 

I am trying to use MDMA with stm32h743zi, but when i set up it on cubeMX, i don't know which channel number to choose.

I looked up information about MDMA but nothing useful found... Any help here to know which number to choose?

As always, thank you so much!

Choose your favorite number, or least favorite one. It doesn't matter.

Don't get hung up on every decision, not everything has an optimal choice.

In case you need more DMA channels later on, at least with other DMAs in H7, the lower the channel number the higher the priority in case of equal priority setting.
