How to use nrf52840 SPIM3 EasyDMA

[Larkin]

Hi，

 now，I am using SPIM3 successfully，

Is EASYDMA also opened by default when I use SPIM3？ If not, how to open it?

Hello,

Yes, if configured correctly. Especially, you need to ensure that the buffers are located in the easyDMA RAM region.
You can see how a normal easyDMA configuration is done here.
You can read more about the SPIM easyDMA functionality here.

Best regards,

Hi，Karl，I have read the document you instructed, but I still don't understand how to operate it， Where can I find the demo code from the SDK ？
