https://test-devzone.nordicsemi.com/f/nordic-q-a/88316/nrf-connect-sdk-v1-9-1---spi-and-i2c---easy-dmaHi, 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 itselfen-USTelligent Community 13 Non-ProductionFri, 27 May 2022 13:51:29 GMThttps://test-devzone.nordicsemi.com/thread/369806?ContentTypeID=1Fri, 27 May 2022 13:51:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b76c4a40-e2e8-4d40-8843-39e855de811euser90815<p>Hi,</p> <p>Please have a look at this guide: <a href="https://test-devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/peripherals/posts/twi-ic2-implementation-with-nrfx-twis-driver">TWI/I2C implementation with nRFx TWIS Driver</a>.</p> [quote user=""]Or the existing drivers for SPI and I2C master are already using dma itself?[/quote] <p>Yes, the SPIM-driver and TWI<span style="text-decoration:underline;">M</span>-driver are both using easyDMA.</p> <ul> <li>Serial Peripheral Interface Master with EasyDMA (SPIM) driver. <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/nrfx/drivers/spim/index.html?highlight=spim">SPIM-driver documentation</a></li> <li>Two Wire Interface Master with EasyDMA (TWIM) peripheral driver. <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/nrfx/drivers/twim/index.html?highlight=twim">TWIM-driver documentation</a>.</li> </ul> [quote user=""]how exactly they are implementing it?[/quote] <p>Please have a brief look at the documentation.
