I cant set up DMA

[demir]

Hi,

I am trying to replicate this example by ST to understand DMA but I come up with below issue when I click on Add. Could you please help me resolve it ?

Hi,

This is just the info/error : DMA impossible, because you didnt activate any peripherals to work with the DMA.

ie:

Select anything you want to work with DMA : SPI , ADC, I2S ... , set it to the mode you want, then you can add a DMA channel there.
