The nrf52 have 3x SPI master/slave with EasyDMA ,Can use the 3 SPI simultaneously to write data to ram with EeayDMA?https://devzone.nordicsemi.com/f/nordic-q-a/31130/the-nrf52-have-3x-spi-master-slave-with-easydma-can-use-the-3-spi-simultaneously-to-write-data-to-ram-with-eeaydmaHi:Nordic Because the nrf52832 can&#39;t read 8bit parallel data from GPIOs to RAM with EeayDMA . So I want to use 3 SPI simultaneously to write data to ram with EeayDMA, can do it ?thanks!en-USTelligent Community 13Mon, 05 Mar 2018 13:25:35 GMTRE: The nrf52 have 3x SPI master/slave with EasyDMA ,Can use the 3 SPI simultaneously to write data to ram with EeayDMA?https://devzone.nordicsemi.com/thread/122828?ContentTypeID=1Mon, 05 Mar 2018 13:25:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fbea27da-42a4-4921-8692-a4793412d931J&#248;rgen Holmefjord<p>Hi,</p> <p>Yes, this should be possible. As described in the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/ahbmultilayer.html?cp=2_1_0_8#ahbmultilayer">documentation</a>, all EasyDMA instaces will act as AHB bus masters, and a peripheral can also <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/easydma.html?cp=2_1_0_9#easydma">implement multiple EasyDMA instances</a>.</p> <p>The SPI instances will get prioritized access to the bus as described in the documentation.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
