Hwo to use DMA interrupt handler

[qoolink]

I have a master device using SPI interface , write data to nordic SPI salve and send data to cell pohone.

But ,the master device SPI wirte data is fast, the nordic will loss data to cell phone.

I will use the SPI interrupt handler to receive SPI data with DMA , then the DMA trigger a DMA interrupt handler to send data to cell phone.

how to use DMA to receive data , and how to create DMA interrupt handler ?

Could you provide the example code?

There is no DMA interrupt hander i believe, which handler are you talking about?
