How to set SPI_TX in DMA settings

[Ruvi2006]

Hi, I’m new to STM32. I wanted to set SPI_TX in DMA settings, but I think it has to be configured before using it, as you can see in the picture. I want to give an output for display... can anyone help to solve the problem?

Hello @Ruvi2006 and welcome to the community;

You can configure GPDMA with 2 possible selections in STM32CubeMx: the Standard Request Mode and the Linked List Mode.

I recommend you to look at these FAQs and get inspired to configure SPI in GPDMA:

-  How to configure the GPDMA 

- How to configure the linked list mode in STM32CubeMX

Also, I think the SPI_FullDuplex_ComDMA_Master.ioc file in SPI_FullDuplex_ComDMA_Master example can help you.

Thank you.

Hi @KDJEM.1 

I don’t know it’s my side issue or something. I tried different SPI pins, but it didn’t work also I tried some examples to check if the board has the issue that not using the SPI it worked perfectly.. Crying Face

Thank you
