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,Karl
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 ？
