nRF Connect SDK v1.9.1 - spi and i2c - easy DMA

Question

Hi, I am trying to implement spi or i2c communication with a sensor using dma in master mode. can anyone give me some sample code on how to get spi/i2c peripheral over easy DMA.
Or the existing drivers for SPI and I2C master are already using dma itself?? if yes how exactly they are implementing it?
thank you.

Hi, 
 Please have a look at this guide: TWI/I2C implementation with nRFx TWIS Driver . 
 Or the existing drivers for SPI and I2C master are already using dma itself? 
 Yes, the SPIM-driver and TWI M -driver are both using easyDMA. 
 
 Serial Peripheral Interface Master with EasyDMA (SPIM) driver. SPIM-driver documentation 
 Two Wire Interface Master with EasyDMA (TWIM) peripheral driver. TWIM-driver documentation . 
 
 how exactly they are implementing it? 
 Please have a brief look at the documentation. Which concepts would you like to learn more about?
