Modifying the SPIS DMA example to do the same would also work for me.
Please navigate to the "Advanced" tab of SPI configuration window and enable interrupts according to your application.
If you require an interrupt to be generated when a transfer is complete, you could enable the following interrupts:
1. Interrupt on SPI done
2. Interrupt on Tx FIFO Empty
