GPDMA Queues & Nodes

Hello, 

 

Does someone have information, project, whatever that can help me understand how do the Queues and Nodes work and interact with each other? 

 

My STM32 has two ADCs, ADC1 & ADC4, and i want to trigger both of them to read values comming from multiple potentiomenters with a timer configured in output compare mode. 

 

The problem is that i have to configure a linkedlist with a Queue and a Node and if i configure two nodes the values of the ADCs seen through the live expression get stuck at 0.

 

Any help is welcomed ...

Hi @Marc3 ,

Just seeing your question now, so I think that the knowledge article How to configure the linked list mode in STM32CubeMX should answer your questions about GPDMA linked list on STM32U5.

My answer may be late for you, but it can be useful for others having similar question as yours.
